If you are a regular contributor, you can request push access to + the repository by creating an account on [[https://savannah.gnu.org/account/register.php][savannah.gnu.org]] and by + [[https://savannah.gnu.org/git/?group=emacs][joining the Emacs group]]. + + After you have been added as a user with push privileges, you can + clone the repository like this: + + : git clone USERNAME@git.savannah.gnu.org:/srv/git/emacs/org-mode.git + + Replace =USERNAME= with your Savannah username. + +4. By requesting push access, you acknowledge that you have read and + agreed with the following rules: + + - Org mode is part of GNU Emacs. Therefore, we need to be very + conscious about changes moving into the Org mode core. These can + originate only from people who have signed the appropriate papers + with the Free Software Foundation. The files to which this + applies are: + + - all *.el files in the lisp directory of the repository + - orgcard.tex and all *.org files in the doc/ directory + + - Before making any significant changes, please explain and discuss + them on the mailing list [[mailto:emacs-orgmode@gnu.org][emacs-orgmode@gnu.org]]. + + This does obviously not apply to people who are maintaining their + own contributions to Org mode. Please just use the new mechanism + to make sure all changes end up in the right place. + + We value a nice tone in our discussions: please check and respect + the [[https://www.gnu.org/philosophy/kind-communication.en.html][GNU Kind Communications Guidelines]]. + + - Org mode no longer uses ChangeLog entries to document changes. + Instead, special commit messages are used, as described in the + `CONTRIBUTE' file in the main Emacs repository. + + - Among other things, Org mode is widely appreciated because of its + simplicity, cleanness and consistency. We should try to preserve + them and ask everyone to keep this in mind when posting changes. + +See [[https://orgmode.org/worg/org-contribute.html][worg/org-contribute]] for guidance on how to contribute effectively. + +* The =contrib/= directory + +The git repository used to contain a =contrib/= directory.

Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs.

To +that end significant effort has been made and continues to be made by +the Org community to ensure that high quality, user focused, +documentation is readily available to everyone. + +Org itself contains a comprehensive guide to using all aspects of the +system, how to extend it yourself, and highlights some of the many +burgeoning number of add-on packages that others are contributing. +This guide, [[info:org:Top][The Org Manual]], concentrates on the facts of working with +the system. Supplementing this, the [[Org web pages]] contain pointers to +many tutorials and how-to's which capture much of spirit and +imagination people show when using Org as a basis for building broader +organizational systems that help them help themselves. + +I use Org, but it is a big system, and so I happen to think that +improving the consistency, clarity and accuracy of Org documents helps +both me and all other users of the system. In support of this and by +way of justification and clarification, this short note attempts to +capture some of the existing guidelines and standards that have been +used in the patches I am submitting and, which I hope, may be adopted +by others when making their own contributions. + +* Referencing systems, packages, modes and much else + +Originally Org was a single mode and there was no ambiguity about what +Org mode could refer to. Things have changed rapidly though and it +seems that Carsten now thinks of Org as the system encompassing the +major mode, some minor modes, and an increasing number of additional +packages and plug-ins that build on the core Org functionality. It is +really hard to find a consistent way to refer to all these things, but +what I am trying to do is follow these guidelines (which are not +perfect, merely a start): + +- In general write "Org" as much as possible and, in particular, when + discussing concepts, features and functions that are generally + applicable to Org as a whole. + +- Be more specific and write, for example, "the Orgtbl minor mode" + when referring to something unique to that feature. It may be, for + example, a command is only available when you are actually editing a + file using just that mode, add-on package or plug-in. + +- Prefer "Org mode" to "Org-mode" or "org-mode". This is simply + because it reflects an existing convention in [[info:emacs:Top][The Emacs Manual]] which + consistently documents mode names in this form - "Text mode", + "Outline mode", "Mail mode", etc. + +- Likewise refer, if at all possible, to "Org file or "Org buffer" + meaning with, great generality, any file or buffer which requires + use of some part of Org to edit it properly. + +- Org uses "org-..." to ring fence a name space for itself in the + Emacs code base. This is obviously retained in code snippets. + +* Other Org specific conventions + +Unless there is a good reason to do otherwise, then try and adopt the +following conventions. (I think all can be justified by reference to +Carsten or precedent in other significant Emacs documentation, unless +I have made them up of course). + +- Org has *lots* of commands and a /lot/ of them take prefix arguments of + one sort or another. Write in full "prefix argument", "numeric + prefix argument" or, maybe, "a numeric prefix argument N" when you + want to refer to the argument again. + +- Org lives in various states of harmony and discord with other Emacs + packages. Try and write the names of those packages as their + authors and maintainers write them. So it should be (I think) BBDB, + MH-E, Rmail, VM, Gnus, CDLaTeX etc. + +- TODO keywords, whether Org or user defined, are written in capitals. + +- Built-in tags with a special meaning (e.g. ARCHIVE) are written in + uppercase. User defined tags (e.g. boss, home) are written in + lowercase. + +- Built-in properties (e.g. PRIORITY) are written in uppercase. User + defined properties (e.g. Release) are written in lowercase. + +- Entries in the concept index are normally all lower case unless some + other rule dictates otherwise. + +* org-manual.org specific conventions + +Org git repository comes with an .org version of the manual in the +=doc/= directory. Here are indications that are specific to this +version of the manual. + +- Five of the standard Texinfo indexes are used in the Org manual: + + + #+cindex: :: concept index, for general concepts + + #+findex: :: function index, for function and function-like names + + #+kindex: :: keystroke index, for keyboard commands + + #+pindex: :: program index, for names of programs + + #+vindex: :: variable index, for variable names + +- Use fixed-width area for one-line examples. + +- Use example blocks for Org syntax instead of "begin_src org". + +- Internal links to headlines always start with a star. + +- Tags, node properties, are not shown with the surrounding colons. + +- When to use = ... = or ~ ... ~ markup: + + + files or extensions use = ... =, + + anything that is meant to be written in the Org buffer uses = ... =, + + any meaningful token in a programming language uses ~ ... ~. + +* Miscellaneous + + - Only two of the standard Texinfo indexes are used; those for + concepts and keys. This has some implications: + + + The preference is to document commands by key rather than by name + + + Texinfo commands such as @var and @defoption are not used. The + preference for this type of thing is that the user browses the + customize groups. If you want or need to refer to, say, a + variable then document it as "the variable + @code{org-startup-folded}" + + + Entries in the concept index are normally all lower case unless + some other rule dictates otherwise. + + - Org documentation is written in American English, which is somewhat + foreign as far as I am concerned, but live with it anyway. + + - Org uses a number of compound words, words that I wouldn't + necessarily run together. Instead of worrying about whether these + should be separate, hyphenated or compound I have simply gone with + the majority case as originally written and then tried to make sure + the spell checker knows what this chosen standard should be so that + I do not worry about it anymore. + + - I have run a spell checker periodically. Aspell works well and has + a useful Texinfo filter (although, annoyingly, I cannot make this + work with ispell.el and so I run it from the command line). I have + an Org specific Aspell configuration file (which sets an American + dictionary, rules for compound words etc) and which, along with the + associated word and replacement files, captures some of the more + detailed and somewhat arbitrary rules I have used. + + - Org has really low entry barriers. Requirements seem simply to be: + + + You can use Text mode or, pretty much, any derivative of it + + You have some motivation to become slightly better organized. + + Therefore, try and write the documentation so that it is relevant + to, and can be read by such a diverse audience. + +# Local variables: +# mode: org +# ispell-local-dictionary: "en_US-w_accents" +# ispell-local-pdict: "./.aspell.org.pws" +# End: diff --git a/elpa/org-9.5.2/doc/Makefile b/elpa/org-9.5.2/doc/Makefile new file mode 100644 index 0000000..cb6d72b --- /dev/null +++ b/elpa/org-9.5.2/doc/Makefile @@ -0,0 +1,102 @@ +.SUFFIXES: # we don't need default suffix rules +ifeq ($(MAKELEVEL), 0) + $(error This make needs to be started as a sub-make from the toplevel directory.) +endif +.PHONY: all info html pdf card manual guide install \ + clean cleanall clean-install + +all: $(ORG_MAKE_DOC) + +info: org orgguide + +html: org.html orgguide.html + +pdf: org.pdf orgguide.pdf + +card: orgcard.pdf orgcard_letter.pdf orgguide.pdf + +ifneq ($(SERVERMK),) +manual guide:: + -$(RMR) $@ + $(MKDIR) $@ +manual:: org.texi org-version.inc + $(TEXI2HTML) -o $@ $< + ../mk/mansplit.pl $@/* +guide:: orgguide.texi org-version.inc + $(TEXI2HTML) -o $@ $< + ../mk/guidesplit.pl $@/* +endif + +org.texi: org-manual.org + $(BATCH) \ + --eval '(add-to-list `load-path "../lisp")' \ + --eval '(load "../mk/org-fixup.el")' \ + --eval '(org-make-manual)' + +orgguide.texi: org-guide.org + $(BATCH) \ + --eval '(add-to-list `load-path "../lisp")' \ + --eval '(load "../mk/org-fixup.el")' \ + --eval '(org-make-guide)' + +org-version.inc: org.texi + @echo "org-version: $(ORGVERSION) ($(GITVERSION))" + @echo "@c automatically generated, do not edit" > org-version.inc + @echo "@set VERSION $(ORGVERSION) ($(GITVERSION))" >> org-version.inc + @echo "@set DATE $(DATE)" >> org-version.inc + +org-version.tex: orgcard.tex + @printf "org-version: $(ORGVERSION) ($(GITVERSION))\n" + @printf "%% automatically generated, do not edit\n" > org-version.tex + @printf "\def\orgversionnumber{$(ORGVERSION)}\n" >> org-version.tex + @printf "\def\\\\versionyear{$(YEAR)}\n" >> org-version.tex + @printf "\def\year{$(YEAR)}\n" >> org-version.tex + +install: org orgguide + if [ ! -d $(DESTDIR)$(infodir) ]; then $(MKDIR) $(DESTDIR)$(infodir); else true; fi ; + $(CP) org.info $(DESTDIR)$(infodir) + $(CP) orgguide.info $(DESTDIR)$(infodir) + $(INSTALL_INFO) --infodir=$(DESTDIR)$(infodir) org.info + $(INSTALL_INFO) --infodir=$(DESTDIR)$(infodir) orgguide.info + +clean: + $(RM) *.pdf *.html *.info *_letter.tex org-version.inc org-version.tex \ + *.aux *.cp *.cps *.dvi *.fn *.fns *.ky *.kys *.pg *.pgs *.toc \ + *.tp *.tps *.vr *.vrs *.log *.ps +cleanall: clean + $(RM) org.texi orgguide.texi + $(RMR) guide manual + +clean-install: + $(RM) $(DESTDIR)$(infodir)/org* + $(INSTALL_INFO) --infodir=$(DESTDIR)$(infodir) --remove org + $(INSTALL_INFO) --infodir=$(DESTDIR)$(infodir) --remove orgguide + +.SUFFIXES: .texi .tex .txt _letter.tex + +%: %.texi org-version.inc + $(MAKEINFO) --no-split $< -o $@.info + +# the following two lines work around a bug in some versions of texi2dvi +%.pdf: LC_ALL=C +%.pdf: LANG=C +%.pdf: %.texi org-version.inc + $(TEXI2PDF) $< +%.pdf: %.tex org-version.tex + PDFLATEX=$(PDFTEX) $(TEXI2PDF) $< + +%.html: %.texi org-version.inc + $(TEXI2HTML) --no-split -o $@ $< +ifneq ($(SERVERMK),) + ../mk/manfull.pl $@ + +%.txt: %.tex + perl ../mk/orgcard2txt.pl $< > $@ +endif + +%_letter.tex: %.tex + $(BATCH) \ + --eval '(add-to-list `load-path "../lisp")' \ + --eval '(load "org-compat.el")' \ + --eval '(load "../mk/org-fixup.el")' \ + --eval '(org-make-letterformat "$(" visits the Emacs manual, etc. + + In Emacs, you can click mouse button 2 on a menu item or cross reference + to select it. + +* Menu: + +Emacs +* Org Mode: (org).

The relationship could be a matter of + historical connection with the subject or with related matters, or + of legal, commercial, philosophical, ethical or political position + regarding them. + + The "Invariant Sections" are certain Secondary Sections whose + titles are designated, as being those of Invariant Sections, in the + notice that says that the Document is released under this License. + If a section does not fit the above definition of Secondary then it + is not allowed to be designated as Invariant. The Document may + contain zero Invariant Sections. If the Document does not identify + any Invariant Sections then there are none. + + The "Cover Texts" are certain short passages of text that are + listed, as Front-Cover Texts or Back-Cover Texts, in the notice + that says that the Document is released under this License. + A Front-Cover Text may be at most 5 words, and a Back-Cover Text + may be at most 25 words. + + A "Transparent" copy of the Document means a machine-readable copy, + represented in a format whose specification is available to the + general public, that is suitable for revising the document + straightforwardly with generic text editors or (for images composed + of pixels) generic paint programs or (for drawings) some widely + available drawing editor, and that is suitable for input to text + formatters or for automatic translation to a variety of formats + suitable for input to text formatters. A copy made in an otherwise + Transparent file format whose markup, or absence of markup, has + been arranged to thwart or discourage subsequent modification by + readers is not Transparent. An image format is not Transparent if + used for any substantial amount of text. A copy that is not + "Transparent" is called "Opaque". + + Examples of suitable formats for Transparent copies include plain + ASCII without markup, Texinfo input format, LaTeX input format, + SGML or XML using a publicly available DTD, and standard-conforming + simple HTML, PostScript or PDF designed for human modification. + Examples of transparent image formats include PNG, XCF and JPG. + Opaque formats include proprietary formats that can be read and + edited only by proprietary word processors, SGML or XML for which + the DTD and/or processing tools are not generally available, and + the machine-generated HTML, PostScript or PDF produced by some word + processors for output purposes only. + + The "Title Page" means, for a printed book, the title page itself, + plus such following pages as are needed to hold, legibly, the + material this License requires to appear in the title page. For + works in formats which do not have any title page as such, "Title + Page" means the text near the most prominent appearance of the + work's title, preceding the beginning of the body of the text. + + The "publisher" means any person or entity that distributes copies + of the Document to the public. + + A section "Entitled XYZ" means a named subunit of the Document + whose title either is precisely XYZ or contains XYZ in parentheses + following text that translates XYZ in another language. (Here XYZ + stands for a specific section name mentioned below, such as + "Acknowledgements", "Dedications", "Endorsements", or "History".) + To "Preserve the Title" of such a section when you modify the + Document means that it remains a section "Entitled XYZ" according + to this definition. + + The Document may include Warranty Disclaimers next to the notice + which states that this License applies to the Document. These + Warranty Disclaimers are considered to be included by reference in + this License, but only as regards disclaiming warranties: any other + implication that these Warranty Disclaimers may have is void and + has no effect on the meaning of this License. + +2. VERBATIM COPYING + + You may copy and distribute the Document in any medium, either + commercially or noncommercially, provided that this License, the + copyright notices, and the license notice saying this License + applies to the Document are reproduced in all copies, and that you + add no other conditions whatsoever to those of this License. You + may not use technical measures to obstruct or control the reading + or further copying of the copies you make or distribute. However, + you may accept compensation in exchange for copies. If you + distribute a large enough number of copies you must also follow the + conditions in section 3. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + +3. COPYING IN QUANTITY + + If you publish printed copies (or copies in media that commonly + have printed covers) of the Document, numbering more than 100, and + the Document's license notice requires Cover Texts, you must + enclose the copies in covers that carry, clearly and legibly, all + these Cover Texts: Front-Cover Texts on the front cover, and + Back-Cover Texts on the back cover. Both covers must also clearly + and legibly identify you as the publisher of these copies. The + front cover must present the full title with all words of the title + equally prominent and visible. You may add other material on the + covers in addition. Copying with changes limited to the covers, as + long as they preserve the title of the Document and satisfy these + conditions, can be treated as verbatim copying in other respects. + + If the required texts for either cover are too voluminous to fit + legibly, you should put the first ones listed (as many as fit + reasonably) on the actual cover, and continue the rest onto + adjacent pages. + + If you publish or distribute Opaque copies of the Document + numbering more than 100, you must either include a machine-readable + Transparent copy along with each Opaque copy, or state in or with + each Opaque copy a computer-network location from which the general + network-using public has access to download using public-standard + network protocols a complete Transparent copy of the Document, free + of added material. If you use the latter option, you must take + reasonably prudent steps, when you begin distribution of Opaque + copies in quantity, to ensure that this Transparent copy will + remain thus accessible at the stated location until at least one + year after the last time you distribute an Opaque copy (directly or + through your agents or retailers) of that edition to the public. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of copies, + to give them a chance to provide you with an updated version of the + Document. + +4. MODIFICATIONS + + You may copy and distribute a Modified Version of the Document + under the conditions of sections 2 and 3 above, provided that you + release the Modified Version under precisely this License, with the + Modified Version filling the role of the Document, thus licensing + distribution and modification of the Modified Version to whoever + possesses a copy of it. In addition, you must do these things in + the Modified Version: + + #+attr_texinfo: :enum A + 1. Use in the Title Page (and on the covers, if any) a title + distinct from that of the Document, and from those of previous + versions (which should, if there were any, be listed in the + History section of the Document). You may use the same title as + a previous version if the original publisher of that version + gives permission. + + 2. List on the Title Page, as authors, one or more persons or + entities responsible for authorship of the modifications in the + Modified Version, together with at least five of the principal + authors of the Document (all of its principal authors, if it has + fewer than five), unless they release you from this requirement. + + 3. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + + 4. Preserve all the copyright notices of the Document. + + 5. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + + 6. Include, immediately after the copyright notices, a license + notice giving the public permission to use the Modified Version + under the terms of this License, in the form shown in the + Addendum below. + + 7. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document's + license notice. + + 8. Include an unaltered copy of this License. + + 9. Preserve the section Entitled "History", Preserve its Title, and + add to it an item stating at least the title, year, new authors, + and publisher of the Modified Version as given on the Title + Page. If there is no section Entitled "History" in the Document, + create one stating the title, year, authors, and publisher of + the Document as given on its Title Page, then add an item + describing the Modified Version as stated in the previous + sentence. + + 10. Preserve the network location, if any, given in the Document + for public access to a Transparent copy of the Document, and + likewise the network locations given in the Document for + previous versions it was based on. These may be placed in the + "History" section. You may omit a network location for a work + that was published at least four years before the Document + itself, or if the original publisher of the version it refers + to gives permission. + + 11. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the section + all the substance and tone of each of the contributor + acknowledgements and/or dedications given therein. + + 12. Preserve all the Invariant Sections of the Document, unaltered + in their text and in their titles. Section numbers or the + equivalent are not considered part of the section titles. + + 13. Delete any section Entitled "Endorsements". Such a section may + not be included in the Modified Version. + + 14. Do not retitle any existing section to be Entitled + "Endorsements" or to conflict in title with any Invariant + Section. + + 15. Preserve any Warranty Disclaimers. + + If the Modified Version includes new front-matter sections or + appendices that qualify as Secondary Sections and contain no material + copied from the Document, you may at your option designate some or all + of these sections as invariant. To do this, add their titles to the + list of Invariant Sections in the Modified Version's license notice. + These titles must be distinct from any other section titles. + + You may add a section Entitled "Endorsements", provided it contains + nothing but endorsements of your Modified Version by various + parties---for example, statements of peer review or that the text has + been approved by an organization as the authoritative definition of a + standard. + + You may add a passage of up to five words as a Front-Cover Text, and a + passage of up to 25 words as a Back-Cover Text, to the end of the list + of Cover Texts in the Modified Version. Only one passage of + Front-Cover Text and one of Back-Cover Text may be added by (or + through arrangements made by) any one entity. If the Document already + includes a cover text for the same cover, previously added by you or + by arrangement made by the same entity you are acting on behalf of, + you may not add another; but you may replace the old one, on explicit + permission from the previous publisher that added the old one. + + The author(s) and publisher(s) of the Document do not by this License + give permission to use their names for publicity for or to assert or + imply endorsement of any Modified Version. + +5. COMBINING DOCUMENTS + + You may combine the Document with other documents released under + this License, under the terms defined in section 4 above for + modified versions, provided that you include in the combination all + of the Invariant Sections of all of the original documents, + unmodified, and list them all as Invariant Sections of your + combined work in its license notice, and that you preserve all + their Warranty Disclaimers. + + The combined work need only contain one copy of this License, and + multiple identical Invariant Sections may be replaced with a single + copy. If there are multiple Invariant Sections with the same name + but different contents, make the title of each such section unique + by adding at the end of it, in parentheses, the name of the + original author or publisher of that section if known, or else + a unique number. Make the same adjustment to the section titles in + the list of Invariant Sections in the license notice of the + combined work. + + In the combination, you must combine any sections Entitled + "History" in the various original documents, forming one section + Entitled "History"; likewise combine any sections Entitled + "Acknowledgements", and any sections Entitled "Dedications". You + must delete all sections Entitled "Endorsements." + +6. COLLECTIONS OF DOCUMENTS + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the documents + in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert + a copy of this License into the extracted document, and follow this + License in all other respects regarding verbatim copying of that + document. + +7. AGGREGATION WITH INDEPENDENT WORKS + + A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of + a storage or distribution medium, is called an "aggregate" if the + copyright resulting from the compilation is not used to limit the + legal rights of the compilation's users beyond what the individual + works permit. When the Document is included in an aggregate, this + License does not apply to the other works in the aggregate which + are not themselves derivative works of the Document. + + If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one half + of the entire aggregate, the Document's Cover Texts may be placed + on covers that bracket the Document within the aggregate, or the + electronic equivalent of covers if the Document is in electronic + form. Otherwise they must appear on printed covers that bracket + the whole aggregate. + +8. TRANSLATION + + Translation is considered a kind of modification, so you may + distribute translations of the Document under the terms of + section 4. Replacing Invariant Sections with translations requires + special permission from their copyright holders, but you may + include translations of some or all Invariant Sections in addition + to the original versions of these Invariant Sections. You may + include a translation of this License, and all the license notices + in the Document, and any Warranty Disclaimers, provided that you + also include the original English version of this License and the + original versions of those notices and disclaimers. In case of + a disagreement between the translation and the original version of + this License or a notice or disclaimer, the original version will + prevail. + + If a section in the Document is Entitled "Acknowledgements", + "Dedications", or "History", the requirement (section 4) to + Preserve its Title (section 1) will typically require changing the + actual title. + +9. TERMINATION + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided under this License. Any attempt + otherwise to copy, modify, sublicense, or distribute it is void, + and will automatically terminate your rights under this License. + + However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly and + finally terminates your license, and (b) permanently, if the + copyright holder fails to notify you of the violation by some + reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from + that copyright holder, and you cure the violation prior to 30 days + after your receipt of the notice. + + Termination of your rights under this section does not terminate + the licenses of parties who have received copies or rights from you + under this License. If your rights have been terminated and not + permanently reinstated, receipt of a copy of some or all of the + same material does not give you any rights to use it. + +10. FUTURE REVISIONS OF THIS LICENSE + + The Free Software Foundation may publish new, revised versions of + the GNU Free Documentation License from time to time. Such new + versions will be similar in spirit to the present version, but may + differ in detail to address new problems or concerns. See + https://www.gnu.org/copyleft/. + + Each version of the License is given a distinguishing version + number. If the Document specifies that a particular numbered + version of this License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that specified version or of any later version that has been + published (not as a draft) by the Free Software Foundation. If + the Document does not specify a version number of this License, + you may choose any version ever published (not as a draft) by the + Free Software Foundation. If the Document specifies that a proxy + can decide which future versions of this License can be used, that + proxy's public statement of acceptance of a version permanently + authorizes you to choose that version for the Document. + +11. RELICENSING + + "Massive Multiauthor Collaboration Site" (or "MMC Site") means any + World Wide Web server that publishes copyrightable works and also + provides prominent facilities for anybody to edit those works. + A public wiki that anybody can edit is an example of such + a server. A "Massive Multiauthor Collaboration" (or "MMC") + contained in the site means any set of copyrightable works thus + published on the MMC site. + + "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 + license published by Creative Commons Corporation, + a not-for-profit corporation with a principal place of business in + San Francisco, California, as well as future copyleft versions of + that license published by that same organization. + + "Incorporate" means to publish or republish a Document, in whole + or in part, as part of another Document. + + An MMC is "eligible for relicensing" if it is licensed under this + License, and if all works that were first published under this + License somewhere other than this MMC, and subsequently + incorporated in whole or in part into the MMC, (1) had no cover + texts or invariant sections, and (2) were thus incorporated prior + to November 1, 2008. + + The operator of an MMC Site may republish an MMC contained in the + site under CC-BY-SA on the same site at any time before August 1, + 2009, provided the MMC is eligible for relicensing. + +#+texinfo: @page + +* ADDENDUM: How to use this License for your documents +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and +license notices just after the title page: + +#+begin_example + Copyright (C) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.3 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts.

For information on how to submit bug +reports, see the main manual. + +* Document Structure +:PROPERTIES: +:DESCRIPTION: A tree works like your brain. +:END: + +Org is an outliner. Outlines allow a document to be organized in +a hierarchical structure, which, least for me, is the best +representation of notes and thoughts. An overview of this structure +is achieved by folding, i.e., hiding large parts of the document to +show only the general document structure and the parts currently being +worked on. Org greatly simplifies the use of outlines by compressing +the entire show and hide functionalities into a single command, +~org-cycle~, which is bound to the {{{kbd(TAB)}}} key. + +** Headlines +:PROPERTIES: +:DESCRIPTION: How to typeset Org tree nodes. +:END: + +Headlines define the structure of an outline tree. The headlines in +Org start on the left margin[fn:1] with one or more stars followed by +a space. For example: + +#+begin_example +,* Top level headline +,** Second level +,*** Third level + some text +,*** Third level + more text +,* Another top level headline +#+end_example + +Note that a headline named after ~org-footnote-section~, which +defaults to =Footnotes=, is considered as special. A subtree with +this headline will be silently ignored by exporting functions. + +Some people find the many stars too noisy and would prefer an outline +that has whitespace followed by a single star as headline starters. +See [[*Miscellaneous]] for a setup to realize this. + +** Visibility Cycling +:PROPERTIES: +:DESCRIPTION: Show and hide, much simplified. +:END: + +Outlines make it possible to hide parts of the text in the buffer. +Org uses just two commands, bound to {{{kbd(TAB)}}} and +{{{kbd{S-TAB)}}} to change the visibility in the buffer. + +#+attr_texinfo: :sep , +- {{{kbd(TAB)}}} :: + + /Subtree cycling/: Rotate current subtree among the states + + : ,-> FOLDED -> CHILDREN -> SUBTREE --. + : '-----------------------------------' + + When called with a prefix argument ({{{kbd(C-u TAB)}}}), or with the + Shift key, global cycling is invoked. + +- {{{kbd(S-TAB)}}}, {{{kbd(C-u TAB)}}} :: + + /Global cycling/: Rotate the entire buffer among the states + + : ,-> OVERVIEW -> CONTENTS -> SHOW ALL --. + : '--------------------------------------' + +- {{{kbd(C-u C-u C-u TAB)}}} :: + + Show all, including drawers. + +When Emacs first visits an Org file, the global state is set to +OVERVIEW, i.e., only the top level headlines are visible. This can be +configured through the variable ~org-startup-folded~, or on a per-file +basis by adding a =STARTUP= keyword to =overview=, =content=, +=showall=, =showeverything= or =showlevels= (n = 2..5) like this: + +: #+STARTUP: content + +** Motion +:PROPERTIES: +:DESCRIPTION: Jumping to other headlines. +:END: + +The following commands jump to other headlines in the buffer. + +- {{{kbd(C-c C-n)}}} :: Next heading. + +- {{{kbd(C-c C-p)}}} :: Previous heading. + +- {{{kbd(C-c C-f)}}} :: Next heading same level. + +- {{{kbd(C-c C-b)}}} :: Previous heading same level. + +- {{{kbd(C-c C-u)}}} :: Backward to higher level heading. + +** Structure Editing +:PROPERTIES: +:DESCRIPTION: Changing sequence and level of headlines. +:END: + +#+attr_texinfo: :sep , +- {{{kbd(M-RET)}}} :: + + Insert new heading with same level as current.

See [[*Refile and + Copy]]. + +- {{{kbd(C-x n s)}}}, {{{kbd(C-x n w)}}} :: + + Narrow buffer to current subtree and widen it again. + +When there is an active region (Transient Mark mode), promotion and +demotion work on all headlines in the region. + +** Sparse Trees +:PROPERTIES: +:DESCRIPTION: Matches embedded in context. +:END: + +An important feature of Org mode is the ability to construct /sparse +trees/ for selected information in an outline tree, so that the entire +document is folded as much as possible, but the selected information +is made visible along with the headline structure above it[fn:3]. +Just try it out and you will see immediately how it works. + +Org mode contains several commands creating such trees, all these +commands can be accessed through a dispatcher: + +- {{{kbd(C-c /)}}} :: + + This prompts for an extra key to select a sparse-tree creating + command. + +- {{{kbd(C-c / r)}}} :: + + Occur. Prompts for a regexp and shows a sparse tree with all + matches. Each match is also highlighted; the highlights disappear + by pressing {{{kbd(C-c C-c)}}}. + + The other sparse tree commands select headings based on TODO + keywords, tags, or properties and will be discussed later in this + manual. + +** Plain Lists +:PROPERTIES: +:DESCRIPTION: Additional structure within an entry. +:END: + +Within an entry of the outline tree, hand-formatted lists can provide +additional structure. They also provide a way to create lists of +checkboxes (see [[*Checkboxes]]). Org supports editing such lists, and +every exporter (see [[*Exporting]]) can parse and format them. + +Org knows ordered lists, unordered lists, and description lists. + +#+attr_texinfo: :indic @bullet +- /Unordered/ list items start with =-=, =+=, or =*= as bullets. + +- /Ordered/ list items start with =1.=, or =1)=. + +- /Description/ list use =::= to separate the /term/ from the + description. + +Items belonging to the same list must have the same indentation on the +first line. An item ends before the next line that is indented like +its bullet/number, or less. A list ends when all items are closed, or +before two blank lines. An example: + +#+begin_example +,* Lord of the Rings + My favorite scenes are (in this order) + 1. The attack of the Rohirrim + 2. Eowyn's fight with the witch king + + this was already my favorite scene in the book + + I really like Miranda Otto. + Important actors in this film are: + - Elijah Wood :: He plays Frodo + - Sean Astin :: He plays Sam, Frodo's friend. +#+end_example + +The following commands act on items when point is in the first line of +an item (the line with the bullet or number). + +#+attr_texinfo: :sep , +- {{{kbd(TAB)}}} :: + + Items can be folded just like headline levels. + +- {{{kbd(M-RET)}}} :: + + Insert new item at current level.

Also verify bullets and indentation + consistency in the whole list. + +- {{{kbd(C-c -)}}} :: + + Cycle the entire list level through the different itemize/enumerate + bullets (=-=, =+=, =*=, =1.=, =1)=). + +* Tables +:PROPERTIES: +:DESCRIPTION: Pure magic for quick formatting. +:END: + +Org comes with a fast and intuitive table editor. Spreadsheet-like +calculations are supported in connection with the Emacs Calc package +(see [[info:calc][GNU Emacs Calculator Manual]]). + +Org makes it easy to format tables in plain ASCII. Any line with =|= +as the first non-whitespace character is considered part of a table. +=|= is also the column separator. A table might look like this: + +#+begin_example +| Name | Phone | Age | +|-------+-------+-----| +| Peter | 1234 | 17 | +| Anna | 4321 | 25 | +#+end_example + +A table is re-aligned automatically each time you press {{{kbd(TAB)}}} +or {{{kbd(RET)}}} or {{{kbd(C-c C-c)}}} inside the table. +{{{kbd(TAB)}}} also moves to the next field ({{{kbd(RET)}}} to the +next row) and creates new table rows at the end of the table or before +horizontal lines. The indentation of the table is set by the first +line. Any line starting with =|-= is considered as a horizontal +separator line and will be expanded on the next re-align to span the +whole table width. So, to create the above table, you would only type + +: |Name|Phone|Age| +: |- + +#+texinfo: @noindent +and then press {{{kbd(TAB)}}} to align the table and start filling in +fields. Even faster would be to type =|Name|Phone|Age= followed by +{{{kbd(C-c RET)}}}. + +When typing text into a field, Org treats {{{kbd(DEL)}}}, +{{{kbd(Backspace)}}}, and all character keys in a special way, so that +inserting and deleting avoids shifting other fields. Also, when +typing /immediately after point was moved into a new field with +{{{kbd(TAB)}}}, {{{kbd(S-TAB)}}} or {{{kbd(RET)}}}/, the field is +automatically made blank. + +** Creation and conversion +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +- {{{kbd(C-c |)}}} :: + + Convert the active region to table. If every line contains at least + one {{{kbd(TAB)}}} character, the function assumes that the material + is tab separated. If every line contains a comma, comma-separated + values (CSV) are assumed. If not, lines are split at whitespace + into fields. + + If there is no active region, this command creates an empty Org + table. But it is easier just to start typing, like {{{kbd(| + N a m e | P h o n e | A g e RET | - TAB)}}}. + +** Re-aligning and field motion +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +#+attr_texinfo: :sep , +- {{{kbd(C-c C-c)}}} :: + + Re-align the table without moving point. + +- {{{kbd(TAB)}}} :: + + Re-align the table, move to the next field.

The position of point indicates + the column to be used for sorting, and the range of lines is the + range between the nearest horizontal separator lines, or the entire + table. + +* Hyperlinks +:PROPERTIES: +:DESCRIPTION: Notes in context. +:END: + +Like HTML, Org provides links inside a file, external links to other +files, Usenet articles, emails, and much more. + +Org recognizes plain URIs, possibly wrapped within angle brackets, and +activate them as clickable links. The general link format, however, +looks like this: + +: [[LINK][DESCRIPTION]] + +#+texinfo: @noindent +or alternatively + +: [[LINK]] + +Once a link in the buffer is complete, with all brackets present, Org +changes the display so that =DESCRIPTION= is displayed instead of +=[[LINK][DESCRIPTION]]= and =LINK= is displayed instead of =[[LINK]]=. +To edit the invisible {{{var(LINK)}}} part, use {{{kbd(C-c C-l)}}} +with the point on the link. + +** Internal links +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +If the link does not look like a URL, it is considered to be internal +in the current file. The most important case is a link like +=[[#my-custom-id]]= which links to the entry with the =CUSTOM_ID= property +=my-custom-id=. + +Links such as =[[My Target]]= or =[[My Target][Find my target]]= lead +to a text search in the current file for the corresponding target, +which looks like =<>=. + +** External Links +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +Org supports links to files, websites, Usenet and email messages, BBDB +database entries and links to both IRC conversations and their logs. +External links are URL-like locators.

Because of its importance, we suggest to bind it +to a widely available key (see [[*Activation]]). It stores a link to the +current location. The link is stored for later insertion into an Org +buffer---see below. + +From an Org buffer, the following commands create, navigate or, more +generally, act on links. + +#+attr_texinfo: :sep , +- {{{kbd(C-c C-l)}}} :: + + Insert a link. This prompts for a link to be inserted into the + buffer. You can just type a link, or use history keys {{{kbd(UP)}}} + and {{{kbd(DOWN)}}} to access stored links. You will be prompted + for the description part of the link. + + When called with a {{{kbd(C-u)}}} prefix argument, file name + completion is used to link to a file. + +- {{{kbd(C-c C-l)}}} (with point on existing link) :: + + When point is on an existing link, {{{kbd(C-c C-l)}}} allows you to + edit the link and description parts of the link. + +- {{{kbd(C-c C-o)}}} :: + + Open link at point. + +- {{{kbd(C-c &)}}} :: + + Jump back to a recorded position.

Using + this command several times in direct succession moves through a ring + of previously recorded positions. + +* TODO Items +:PROPERTIES: +:DESCRIPTION: Every tree branch can be a TODO item. +:END: + +Org mode does not require TODO lists to live in separate documents. +Instead, TODO items are part of a notes file, because TODO items +usually come up while taking notes! With Org mode, simply mark any +entry in a tree as being a TODO item. In this way, information is not +duplicated, and TODO items remain in the context from which they +emerged. + +Org mode provides methods to give you an overview of all the things +that you have to do, collected from many files. + +** Basic TODO Functionality +:PROPERTIES: +:DESCRIPTION: Marking and displaying TODO entries. +:ALT_TITLE: TODO Basics +:END: + +Any headline becomes a TODO item when it starts with the word =TODO=, +for example: + +: *** TODO Write letter to Sam Fortune + +The most important commands to work with TODO entries are: + +#+attr_texinfo: :sep , +- {{{kbd(C-c C-t)}}} :: + + Rotate the TODO state of the current item among + + : ,-> (unmarked) -> TODO -> DONE --. + : '--------------------------------' + + The same rotation can also be done "remotely" from the agenda buffer + with the {{{kbd(t)}}} command key (see [[*Commands in the Agenda + Buffer]]). + +- {{{kbd(S-RIGHT)}}}, {{{kbd(S-LEFT)}}} :: + + Select the following/preceding TODO state, similar to cycling. + +- {{{kbd(C-c / t)}}} :: + + View TODO items in a /sparse tree/ (see [[*Sparse Trees]]).

See [[*The Global TODO List]], for more information. + +- {{{kbd(S-M-RET)}}} :: + + Insert a new TODO entry below the current one. + +Changing a TODO state can also trigger tag changes. See the docstring +of the option ~org-todo-state-tags-triggers~ for details. + +** Multi-state Workflow +:PROPERTIES: +:DESCRIPTION: More than just on/off. +:END: + +You can use TODO keywords to indicate @emph{sequential} working progress +states: + +#+begin_src emacs-lisp +(setq org-todo-keywords + '((sequence "TODO" "FEEDBACK" "VERIFY" "|" "DONE" "DELEGATED"))) +#+end_src + +#+texinfo: @noindent +The vertical bar separates the =TODO= keywords (states that /need +action/) from the =DONE= states (which need /no further action/). If +you do not provide the separator bar, the last state is used as the +=DONE= state. With this setup, the command {{{kbd(C-c C-t)}}} cycles +an entry from =TODO= to =FEEDBACK=, then to =VERIFY=, and finally to +=DONE= and =DELEGATED=. + +Sometimes you may want to use different sets of TODO keywords in +parallel. For example, you may want to have the basic =TODO=/=DONE=, +but also a workflow for bug fixing. Your setup would then look like +this: + +#+begin_src emacs-lisp +(setq org-todo-keywords + '((sequence "TODO(t)" "|" "DONE(d)") + (sequence "REPORT(r)" "BUG(b)" "KNOWNCAUSE(k)" "|" "FIXED(f)"))) +#+end_src + +#+texinfo: @noindent +The keywords should all be different, this helps Org mode to keep +track of which subsequence should be used for a given entry. The +example also shows how to define keys for fast access of a particular +state, by adding a letter in parenthesis after each keyword---you will +be prompted for the key after {{{kbd(C-c C-t)}}}. + +To define TODO keywords that are valid only in a single file, use the +following text anywhere in the file. + +#+begin_example +,#+TODO: TODO(t) | DONE(d) +,#+TODO: REPORT(r) BUG(b) KNOWNCAUSE(k) | FIXED(f) +,#+TODO: | CANCELED(c) +#+end_example + +After changing one of these lines, use {{{kbd(C-c C-c)}}} with the +cursor still in the line to make the changes known to Org mode. + +** Progress Logging +:PROPERTIES: +:DESCRIPTION: Dates and notes for progress. +:END: + +To record a timestamp and a note when changing a TODO state, call the +command ~org-todo~ with a prefix argument. + +#+attr_texinfo: :sep , +- {{{kbd(C-u C-c C-t)}}} :: + Prompt for a note and record a the time of the TODO state change. + +Org mode can also automatically record a timestamp and optionally a +note when you mark a TODO item as DONE, or even each time you change +the state of a TODO item. This system is highly configurable, +settings can be on a per-keyword basis and can be localized to a file +or even a subtree. For information on how to clock working time for a +task, see [[*Clocking Work Time]]. + +*** Closing items +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +The most basic logging is to keep track of /when/ a certain TODO item +was marked as done. This can be achieved with[fn:4] + +#+begin_src emacs-lisp +(setq org-log-done 'time) +#+end_src + +#+texinfo: @noindent +Then each time you turn an entry from a TODO (not-done) state into any +of the DONE states, a line =CLOSED: [timestamp]= is inserted just +after the headline. + +If you want to record a note along with the timestamp, use[fn:5] + +#+begin_src emacs-lisp +(setq org-log-done 'note) +#+end_src + +#+texinfo: @noindent +You are then be prompted for a note, and that note is stored below the +entry with a =Closing Note= heading. + +*** Tracking TODO state changes +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +You might want to keep track of TODO state changes. You can either +record just a timestamp, or a time-stamped note for a change. These +records are inserted after the headline as an itemized list. When +taking a lot of notes, you might want to get the notes out of the way +into a drawer. Customize the variable ~org-log-into-drawer~ to get +this behavior. + +For state logging, Org mode expects configuration on a per-keyword +basis. This is achieved by adding special markers =!= (for +a timestamp) and =@= (for a note) in parentheses after each keyword. +For example: + +: #+TODO: TODO(t) WAIT(w@/!) | DONE(d!) CANCELED(c@) + +#+texinfo: @noindent +defines TODO keywords and fast access keys, and also request that +a time is recorded when the entry is set to =DONE=, and that a note is +recorded when switching to =WAIT= or =CANCELED=. The same syntax +works also when setting ~org-todo-keywords~. + +** Priorities +:PROPERTIES: +:DESCRIPTION: Some things are more important than others. +:END: + +If you use Org mode extensively, you may end up with enough TODO items +that it starts to make sense to prioritize them. Prioritizing can be +done by placing a /priority cookie/ into the headline of a TODO item, +like this + +: *** TODO [#A] Write letter to Sam Fortune + +Org mode supports three priorities: =A=, =B=, and =C=. =A= is the +highest, =B= the default if none is given. Priorities make +a difference only in the agenda. + +#+attr_texinfo: :sep ; +- {{{kbd(C-c \,)}}} :: + + Set the priority of the current headline. Press {{{kbd(A)}}}, + {{{kbd(B)}}} or {{{kbd(C)}}} to select a priority, or {{{kbd(SPC)}}} + to remove the cookie. + +- {{{kbd(S-UP)}}} (~org-priority-up~); {{{kbd(S-DOWN)}}} (~org-priority-down~) :: + + Increase/decrease the priority of the current headline. + +** Breaking Tasks Down into Subtasks +:PROPERTIES: +:DESCRIPTION: Splitting a task into manageable pieces. +:ALT_TITLE: Breaking Down Tasks +:END: + +It is often advisable to break down large tasks into smaller, +manageable subtasks. You can do this by creating an outline tree +below a TODO item, with detailed subtasks on the tree. To keep an +overview of the fraction of subtasks that have already been marked +as done, insert either =[/]= or =[%]= anywhere in the headline. These +cookies are updated each time the TODO status of a child changes, or +when pressing {{{kbd(C-c C-c)}}} on the cookie. For example: + +#+begin_example +,* Organize Party [33%] +,** TODO Call people [1/2] +,*** TODO Peter +,*** DONE Sarah +,** TODO Buy food +,** DONE Talk to neighbor +#+end_example + +** Checkboxes +:PROPERTIES: +:DESCRIPTION: Tick-off lists. +:END: + +Every item in a plain list (see [[*Plain Lists]]) can be made into +a checkbox by starting it with the string =[ ]=. Checkboxes are not +included into the global TODO list, so they are often great to split +a task into a number of simple steps. + +Here is an example of a checkbox list. + +#+begin_example +,* TODO Organize party [2/4] + - [-] call people [1/2] + - [ ] Peter + - [X] Sarah + - [X] order food +#+end_example + +Checkboxes work hierarchically, so if a checkbox item has children +that are checkboxes, toggling one of the children checkboxes makes the +parent checkbox reflect if none, some, or all of the children are +checked. + +The following commands work with checkboxes: + +- {{{kbd(C-c C-c)}}} :: + + Toggle checkbox status or---with prefix argument---checkbox presence + at point. + +- {{{kbd(M-S-RET)}}} :: + + Insert a new item with a checkbox. This works only if point is + already in a plain list item (see [[*Plain Lists]]). + +* Tags +:PROPERTIES: +:DESCRIPTION: Tagging headlines and matching sets of tags. +:END: + +An excellent way to implement labels and contexts for +cross-correlating information is to assign /tags/ to headlines. Org +mode has extensive support for tags. + +Every headline can contain a list of tags; they occur at the end of +the headline. Tags are normal words containing letters, numbers, =_=, +and =@=. Tags must be preceded and followed by a single colon, e.g., +=:work:=. Several tags can be specified, as in =:work:urgent:=. Tags +by default are in bold face with the same color as the headline. + +** Tag inheritance +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +Tags make use of the hierarchical structure of outline trees. If +a heading has a certain tag, all subheadings inherit the tag as well. +For example, in the list + +#+begin_example +,* Meeting with the French group :work: +,** Summary by Frank :boss:notes: +,*** TODO Prepare slides for him :action: +#+end_example + +#+texinfo: @noindent +the final heading has the tags =work=, =boss=, =notes=, and =action= +even though the final heading is not explicitly marked with those +tags. + +You can also set tags that all entries in a file should inherit just +as if these tags were defined in a hypothetical level zero that +surrounds the entire file. Use a line like this[fn:6]: + +: #+FILETAGS: :Peter:Boss:Secret: + +** Setting tags +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +Tags can simply be typed into the buffer at the end of a headline. +After a colon, {{{kbd(M-TAB)}}} offers completion on tags. There is +also a special command for inserting tags: + +- {{{kbd(C-c C-q)}}} :: + + Enter new tags for the current headline. Org mode either offers + completion or a special single-key interface for setting tags, see + below. + +- {{{kbd(C-c C-c)}}} :: + + When point is in a headline, this does the same as {{{kbd(C-c + C-q)}}}. + +Org supports tag insertion based on a /list of tags/. By default this +list is constructed dynamically, containing all tags currently used in +the buffer. You may also globally specify a hard list of tags with +the variable ~org-tag-alist~. Finally you can set the default tags +for a given file using the =TAGS= keyword, like + +: #+TAGS: @work @home @tennisclub +: #+TAGS: laptop car pc sailboat + +By default Org mode uses the standard minibuffer completion facilities +for entering tags. However, it also implements another, quicker, tag +selection method called /fast tag selection/. This allows you to +select and deselect tags with just a single key press. For this to +work well you should assign unique letters to most of your commonly +used tags. You can do this globally by configuring the variable +~org-tag-alist~ in your Emacs init file. For example, you may find +the need to tag many items in different files with =@home=. In this +case you can set something like: + +#+begin_src emacs-lisp +(setq org-tag-alist '(("@work" . ?w) ("@home" . ?h) ("laptop" . ?l))) +#+end_src + +If the tag is only relevant to the file you are working on, then you +can instead set the =TAGS= keyword as: + +: #+TAGS: @work(w) @home(h) @tennisclub(t) laptop(l) pc(p) + +** Tag groups +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +A tag can be defined as a /group tag/ for a set of other tags. The +group tag can be seen as the "broader term" for its set of tags. + +You can set group tags by using brackets and inserting a colon between +the group tag and its related tags: + +: #+TAGS: [ GTD : Control Persp ] + +#+texinfo: @noindent +or, if tags in the group should be mutually exclusive: + +: #+TAGS: { Context : @Home @Work } + +When you search for a group tag, it return matches for all members in +the group and its subgroups. In an agenda view, filtering by a group +tag displays or hide headlines tagged with at least one of the members +of the group or any of its subgroups. + +If you want to ignore group tags temporarily, toggle group tags +support with ~org-toggle-tags-groups~, bound to {{{kbd(C-c C-x q)}}}. + +** Tag searches +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +- {{{kbd(C-c / m)}}} or {{{kbd(C-c \)}}} :: + + Create a sparse tree with all headlines matching a tags search. + With a {{{kbd(C-u)}}} prefix argument, ignore headlines that are not + a TODO line. + +- {{{kbd(M-x org-agenda m)}}} :: + + Create a global list of tag matches from all agenda files.

The full syntax of +the search string is rich and allows also matching against TODO +keywords, entry levels and properties. For a more detailed description +with many examples, see [[*Matching Tags and Properties]]. + +* Properties +:PROPERTIES: +:DESCRIPTION: Storing information about an entry. +:END: + +Properties are key-value pairs associated with an entry. They live in +a special drawer with the name =PROPERTIES=.

This special property is /inherited/, +so if you set it in a level 1 entry, it applies to the entire tree. +When allowed values are defined, setting the corresponding property +becomes easier and is less prone to typing errors. For the example +with the CD collection, we can pre-define publishers and the number of +disks in a box like this: + +#+begin_example +,* CD collection + :PROPERTIES: + :NDisks_ALL: 1 2 3 4 + :Publisher_ALL: "Deutsche Grammophon" Philips EMI + :END: +#+end_example + +If you want to set properties that can be inherited by any entry in +a file, use a line like: + +: #+PROPERTY: NDisks_ALL 1 2 3 4 + +The following commands help to work with properties: + +- {{{kbd(C-c C-x p)}}} :: + + Set a property.

The syntax for the search string is described in [[*Matching +Tags and Properties]]. + +* Dates and Times +:PROPERTIES: +:DESCRIPTION: Making items useful for planning. +:END: + +To assist project planning, TODO items can be labeled with a date +and/or a time. The specially formatted string carrying the date and +time information is called a /timestamp/ in Org mode. + +** Timestamps +:PROPERTIES: +:DESCRIPTION: Assigning a time to a tree entry. +:END: + +A timestamp is a specification of a date---possibly with a time or +a range of times---in a special format, either =<2003-09-16 Tue>= or +=<2003-09-16 Tue 09:39>= or =<2003-09-16 Tue 12:00-12:30>=. +A timestamp can appear anywhere in the headline or body of an Org tree +entry.

It +also is an authoring system with unique support for literate +programming and reproducible research. + +Org is implemented on top of Outline mode, which makes it possible to +keep the content of large files well structured. Visibility cycling +and structure editing help to work with the tree. Tables are easily +created with a built-in table editor. Plain text URL-like links +connect to websites, emails, Usenet messages, BBDB entries, and any +files related to the projects. + +Org develops organizational tasks around notes files that contain +lists or information about projects as plain text. Project planning +and task management make use of metadata which is part of an outline +node. Based on this data, specific entries can be extracted in +queries and create dynamic /agenda views/ that also integrate the +Emacs calendar and diary. Org can be used to implement many different +project planning schemes, such as David Allen's GTD system. + +Org files can serve as a single source authoring system with export to +many different formats such as HTML, LaTeX, Open Document, and +Markdown. New export backends can be derived from existing ones, or +defined from scratch. + +Org files can include source code blocks, which makes Org uniquely +suited for authoring technical documents with code examples. Org +source code blocks are fully functional; they can be evaluated in +place and their results can be captured in the file. This makes it +possible to create a single file reproducible research compendium. + +Org keeps simple things simple. When first fired up, it should feel +like a straightforward, easy to use outliner. Complexity is not +imposed, but a large amount of functionality is available when needed. +Org is a toolbox. Many users actually run only a---very +personal---fraction of Org's capabilities, and know that there is more +whenever they need it. + +All of this is achieved with strictly plain text files, the most +portable and future-proof file format. Org runs in Emacs.

Here is how to produce a useful backtrace: + +1. Reload uncompiled versions of all Org mode Lisp files. The + backtrace contains much more information if it is produced with + uncompiled code. To do this, use + + : C-u M-x org-reload + + #+texinfo: @noindent + or, from the menu: Org \rarr Refresh/Reload \rarr Reload Org uncompiled. + +2. Then, activate the debugger: + + : M-x toggle-debug-on-error + + #+texinfo: @noindent + or, from the menu: Options \rarr Enter Debugger on Error. + +3. Do whatever you have to do to hit the error. Do not forget to + document the steps you take. + +4. When you hit the error, a =*Backtrace*= buffer appears on the + screen.

Like +in any other spreadsheet, you may reference fields with +a letter/number combination like =B3=, meaning the second field in the +third row. However, Org prefers to use another, more general +representation that looks like this:[fn:18] + +: @ROW$COLUMN + +Column specifications can be absolute like =$1=, =$2=, ..., =$N=, or +relative to the current column, i.e., the column of the field which is +being computed, like =$+1= or =$-2=. =$<= and =$>= are immutable +references to the first and last column, respectively, and you can use +=$>>>= to indicate the third column from the right. + +The row specification only counts data lines and ignores horizontal +separator lines, or "hlines". Like with columns, you can use absolute +row numbers =@1=, =@2=, ..., =@N=, and row numbers relative to the +current row like =@+3= or =@-1=. =@<= and =@>= are immutable +references the first and last row in the table, respectively. You may +also specify the row relative to one of the hlines: =@I= refers to the +first hline, =@II= to the second, etc. =@-I= refers to the first such +line above the current line, =@+I= to the first such line below the +current line. You can also write =@III+2= which is the second data +line after the third hline in the table. + +=@0= and =$0= refer to the current row and column, respectively, i.e., +to the row/column for the field being computed. Also, if you omit +either the column or the row part of the reference, the current +row/column is implied. + +Org's references with /unsigned/ numbers are fixed references in the +sense that if you use the same reference in the formula for two +different fields, the same field is referenced each time. Org's +references with /signed/ numbers are floating references because the +same reference operator can reference different fields depending on +the field being calculated by the formula. + +Here are a few examples: + +#+attr_texinfo: :columns 0.2 0.8 +| =@2$3= | 2nd row, 3rd column (same as =C2=) | +| =$5= | column 5 in the current row (same as =E&=) | +| =@2= | current column, row 2 | +| =@-1$-3= | field one row up, three columns to the left | +| =@-I$2= | field just under hline above current row, column 2 | +| =@>$5= | field in the last row, in column 5 | + +**** Range references +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +#+cindex: range references +#+cindex: references, to ranges +You may reference a rectangular range of fields by specifying two +field references connected by two dots =..=.

In addition or alternatively, depending on the value of + ~org-id-link-to-org-use-id~, create and/or use a globally unique + =ID= property for the link[fn:29]. So using this command in Org + buffers potentially creates two links: a human-readable link from + the custom ID, and one that is globally unique and works even if the + entry is moved from file to file. The =ID= property can be either a + UUID (default) or a timestamp, depending on ~org-id-method~.

You may also use a numeric prefix argument to quickly +select a specific state. For example {{{kbd(C-3 C-c C-t)}}} changes +the state immediately to =VERIFY=. Or you can use {{{kbd(S-RIGHT)}}} +and {{{kbd(S-LEFT)}}} to go forward and backward through the states. +If you define many keywords, you can use in-buffer completion (see +[[*Completion]]) or a special one-key selection scheme (see [[*Fast +access to TODO states]]) to insert these words into the buffer. +Changing a TODO state can be logged with a timestamp, see [[*Tracking +TODO state changes]], for more information. + +*** TODO keywords as types +:PROPERTIES: +:DESCRIPTION: I do this, Fred does the rest. +:ALT_TITLE: TODO types +:END: +#+cindex: TODO types +#+cindex: names as TODO keywords +#+cindex: types as TODO keywords + +The second possibility is to use TODO keywords to indicate different +/types/ of action items. For example, you might want to indicate that +items are for "work" or "home". Or, when you work with several people +on a single project, you might want to assign action items directly to +persons, by using their names as TODO keywords. This type of +functionality is actually much better served by using tags (see +[[*Tags]]), so the TODO implementation is kept just for backward +compatibility. + +Using TODO types, it would be set up like this: + +#+begin_src emacs-lisp +(setq org-todo-keywords '((type "Fred" "Sara" "Lucy" "|" "DONE"))) +#+end_src + +In this case, different keywords do not indicate states, but +rather different types. So the normal work flow would be to assign +a task to a person, and later to mark it DONE. Org mode supports this +style by adapting the workings of the command {{{kbd(C-c +C-t)}}}[fn:37]. When used several times in succession, it still +cycles through all names, in order to first select the right type for +a task. But when you return to the item after some time and execute +{{{kbd(C-c C-t)}}} again, it will switch from any name directly to +=DONE=. Use prefix arguments or completion to quickly select +a specific name. You can also review the items of a specific TODO +type in a sparse tree by using a numeric prefix to {{{kbd(C-c / t)}}}. +For example, to see all things Lucy has to do, you would use +{{{kbd(C-3 C-c / t)}}}. To collect Lucy's items from all agenda files +into a single buffer, you would use the numeric prefix argument as +well when creating the global TODO list: {{{kbd(C-3 M-x org-agenda +t)}}}. + +*** Multiple keyword sets in one file +:PROPERTIES: +:DESCRIPTION: Mixing it all, still finding your way. +:ALT_TITLE: Multiple sets in one file +:END: +#+cindex: TODO keyword sets + +Sometimes you may want to use different sets of TODO keywords in +parallel. For example, you may want to have the basic TODO/DONE, but +also a workflow for bug fixing, and a separate state indicating that +an item has been canceled---so it is not DONE, but also does not +require action. Your setup would then look like this: + +#+begin_src emacs-lisp +(setq org-todo-keywords + '((sequence "TODO" "|" "DONE") + (sequence "REPORT" "BUG" "KNOWNCAUSE" "|" "FIXED") + (sequence "|" "CANCELED"))) +#+end_src + +The keywords should all be different, this helps Org mode keep track +of which subsequence should be used for a given entry. In this setup, +{{{kbd(C-c C-t)}}} only operates within a sub-sequence, so it switches +from =DONE= to (nothing) to =TODO=, and from =FIXED= to (nothing) to +=REPORT=. Therefore you need a mechanism to initially select the +correct sequence. In addition to typing a keyword or using completion +(see [[*Completion]]), you may also apply the following commands: + +#+attr_texinfo: :sep , +- {{{kbd(C-u C-u C-c C-t)}}}, {{{kbd(C-S-RIGHT)}}}, {{{kbd(C-S-LEFT)}}} :: + + #+kindex: C-S-RIGHT + #+kindex: C-S-LEFT + #+kindex: C-u C-u C-c C-t + These keys jump from one TODO sub-sequence to the next. In the + above example, {{{kbd(C-u C-u C-c C-t)}}} or {{{kbd(C-S-RIGHT)}}} + would jump from =TODO= or =DONE= to =REPORT=, and any of the words + in the second row to =CANCELED=. Note that the {{{kbd(C-S-)}}} key + binding conflict with shift-selection (see [[*Packages that conflict + with Org mode]]). + +- {{{kbd(S-RIGHT)}}}, {{{kbd(S-LEFT)}}} :: + + #+kindex: S-RIGHT + #+kindex: S-LEFT + {{{kbd(S-LEFT)}}} and {{{kbd(S-RIGHT)}}} walk through /all/ keywords + from all sub-sequences, so for example {{{kbd(S-RIGHT)}}} would + switch from =DONE= to =REPORT= in the example above.

If you customize the variable +~org-enforce-todo-dependencies~, Org blocks entries from changing +state to DONE while they have TODO children that are not DONE. +Furthermore, if an entry has a property =ORDERED=, each of its TODO +children is blocked until all earlier siblings are marked as done. +Here is an example: + +#+begin_example +,* TODO Blocked until (two) is done +,** DONE one +,** TODO two + +,* Parent +:PROPERTIES: +:ORDERED: t +:END: +,** TODO a +,** TODO b, needs to wait for (a) +,** TODO c, needs to wait for (a) and (b) +#+end_example + +#+cindex: TODO dependencies, @samp{NOBLOCKING} +#+cindex: @samp{NOBLOCKING}, property +You can ensure an entry is never blocked by using the =NOBLOCKING= +property (see [[*Properties and Columns]]): + +#+begin_example +,* This entry is never blocked +:PROPERTIES: +:NOBLOCKING: t +:END: +#+end_example + +- {{{kbd(C-c C-x o)}}} (~org-toggle-ordered-property~) :: + + #+kindex: C-c C-x o + #+findex: org-toggle-ordered-property + #+vindex: org-track-ordered-property-with-tag + Toggle the =ORDERED= property of the current entry.

Customize the variable +~org-log-into-drawer~ to get this behavior---the recommended drawer +for this is called =LOGBOOK=[fn:44]. You can also overrule the +setting of this variable for a subtree by setting a =LOG_INTO_DRAWER= +property. + +Since it is normally too much to record a note for every state, Org +mode expects configuration on a per-keyword basis for this.

For +example, with the setting + +#+begin_src emacs-lisp +(setq org-todo-keywords + '((sequence "TODO(t)" "WAIT(w@/!)" "|" "DONE(d!)" "CANCELED(c@)"))) +#+end_src + +#+vindex: org-log-done +You not only define global TODO keywords and fast access keys, but +also request that a time is recorded when the entry is set to =DONE=, +and that a note is recorded when switching to =WAIT= or +=CANCELED=[fn:45]. The setting for =WAIT= is even more special: the +=!= after the slash means that in addition to the note taken when +entering the state, a timestamp should be recorded when /leaving/ the +=WAIT= state, if and only if the /target/ state does not configure +logging for entering it. So it has no effect when switching from +=WAIT= to =DONE=, because =DONE= is configured to record a timestamp +only. But when switching from =WAIT= back to =TODO=, the =/!= in the +=WAIT= setting now triggers a timestamp even though =TODO= has no +logging configured. + +You can use the exact same syntax for setting logging preferences local +to a buffer: + +: #+TODO: TODO(t) WAIT(w@/!) | DONE(d!)

To use habits, you have to enable the ~habits~ +module by customizing the variable ~org-modules~. + +A habit has the following properties: + +1. The habit is a TODO item, with a TODO keyword representing an open + state. + +2. The property =STYLE= is set to the value =habit= (see [[*Properties + and Columns]]). + +3. The TODO has a scheduled date, usually with a =.+= style repeat + interval. A =++= style may be appropriate for habits with time + constraints, e.g., must be done on weekends, or a =+= style for an + unusual habit that can have a backlog, e.g., weekly reports. + +4. The TODO may also have minimum and maximum ranges specified by + using the syntax =.+2d/3d=, which says that you want to do the task + at least every three days, but at most every two days. + +5. State logging for the DONE state is enabled (see [[*Tracking TODO + state changes]]), in order for historical data to be represented in + the consistency graph.

If today is the 15th, then the habit first appears in the +agenda (see [[*Agenda Views]]) on Oct 17, after the minimum of 2 days has +elapsed, and will appear overdue on Oct 19, after four days have +elapsed. + +What's really useful about habits is that they are displayed along +with a consistency graph, to show how consistent you've been at +getting that task done in the past.

In this +case you can set something like: + +#+begin_src emacs-lisp +(setq org-tag-alist '(("@work" . ?w) ("@home" . ?h) ("laptop" . ?l))) +#+end_src + +If the tag is only relevant to the file you are working on, then you +can instead set the =TAGS= keyword as: + +: #+TAGS: @work(w) @home(h) @tennisclub(t) laptop(l) pc(p) + +The tags interface shows the available tags in a splash window.

Multiple such groups are allowed. + +Do not forget to press {{{kbd(C-c C-c)}}} with point in one of these +lines to activate any changes. + +To set these mutually exclusive groups in the variable +~org-tags-alist~, you must use the dummy tags ~:startgroup~ and +~:endgroup~ instead of the braces. Similarly, you can use ~:newline~ +to indicate a line break. The previous example would be set globally +by the following configuration: + +#+begin_src emacs-lisp +(setq org-tag-alist '((:startgroup . nil) + ("@work" . ?w) ("@home" . ?h) + ("@tennisclub" . ?t) + (:endgroup . nil) + ("laptop" . ?l) ("pc" . ?p))) +#+end_src + +If at least one tag has a selection key then pressing {{{kbd(C-c +C-c)}}} automatically presents you with a special interface, listing +inherited tags, the tags of the current headline, and a list of all +valid tags with corresponding keys[fn:54]. + +Pressing keys assigned to tags adds or removes them from the list of +tags in the current line.

Switching from =@home= to =@work= +would be done with {{{kbd(C-c C-c w RET)}}} or alternatively with +{{{kbd(C-c C-c C-c w)}}}. Adding the non-predefined tag =sarah= could +be done with {{{kbd(C-c C-c TAB s a r a h RET)}}}. + +#+vindex: org-fast-tag-selection-single-key +If you find that most of the time you need only a single key press to +modify your list of tags, set the variable +~org-fast-tag-selection-single-key~.

Properties +can be set so they are associated with a single entry, with every +entry in a tree, or with the whole buffer. + +There are two main applications for properties in Org mode. First, +properties are like tags, but with a value. Imagine maintaining +a file where you document bugs and plan releases for a piece of +software. Instead of using tags like =release_1=, =release_2=, you +can use a property, say =Release=, that in different subtrees has +different values, such as =1.0= or =2.0=. Second, you can use +properties to implement (very basic) database capabilities in an Org +buffer. Imagine keeping track of your music CDs, where properties +could be things such as the album, artist, date of release, number of +tracks, and so on. + +Properties can be conveniently edited and viewed in column view (see +[[*Column View]]). + +** Property Syntax +:PROPERTIES: +:DESCRIPTION: How properties are spelled out. +:END: +#+cindex: property syntax +#+cindex: drawer, for properties + +Properties are key--value pairs.

Each property is specified on +a single line, with the key---surrounded by colons---first, and the +value after it. Keys are case-insensitive. Here is an example: + +#+begin_example +,* CD collection +,** Classic +,*** Goldberg Variations + :PROPERTIES: + :Title: Goldberg Variations + :Composer: J.S.

This special property is /inherited/, +so if you set it in a level 1 entry, it applies to the entire tree. +When allowed values are defined, setting the corresponding property +becomes easier and is less prone to typing errors.

Org mode helps to +organize such tasks using a so-called repeater in a =DEADLINE=, +=SCHEDULED=, or plain timestamps[fn:69]. In the following example: + +#+begin_example +,** TODO Pay the rent + DEADLINE: <2005-10-01 Sat +1m> +#+end_example + +#+texinfo: @noindent +the =+1m= is a repeater; the intended interpretation is that the task +has a deadline on =<2005-10-01>= and repeats itself every (one) month +starting from that time. You can use yearly, monthly, weekly, daily +and hourly repeat cookies by using the =y=, =m=, =w=, =d= and =h= +letters. If you need both a repeater and a special warning period in +a deadline entry, the repeater should come first and the warning +period last + +: DEADLINE: <2005-10-01 Sat +1m -3d> + +#+vindex: org-todo-repeat-to-state +Deadlines and scheduled items produce entries in the agenda when they +are over-due, so it is important to be able to mark such an entry as +done once you have done so. When you mark a =DEADLINE= or +a =SCHEDULED= with the TODO keyword =DONE=, it no longer produces +entries in the agenda. The problem with this is, however, is that +then also the /next/ instance of the repeated entry will not be +active. Org mode deals with this in the following way: when you try +to mark such an entry as done, using {{{kbd(C-c C-t)}}}, it shifts the +base date of the repeating timestamp by the repeater interval, and +immediately sets the entry state back to TODO[fn:70]. In the example +above, setting the state to =DONE= would actually switch the date like +this: + +#+begin_example +,** TODO Pay the rent + DEADLINE: <2005-11-01 Tue +1m> +#+end_example + +To mark a task with a repeater as DONE, use {{{kbd(C-- 1 C-c C-t)}}}, +i.e., ~org-todo~ with a numeric prefix argument of =-1=. + +#+vindex: org-log-repeat +A timestamp[fn:71] is added under the deadline, to keep a record that +you actually acted on the previous instance of this deadline. + +As a consequence of shifting the base date, this entry is no longer +visible in the agenda when checking past dates, but all future +instances will be visible. + +With the =+1m= cookie, the date shift is always exactly one month. So +if you have not paid the rent for three months, marking this entry +DONE still keeps it as an overdue deadline. Depending on the task, +this may not be the best way to handle it. For example, if you forgot +to call your father for 3 weeks, it does not make sense to call him +3 times in a single day to make up for it. Finally, there are tasks, +like changing batteries, which should always repeat a certain time +/after/ the last time you did it. For these tasks, Org mode has +special repeaters =++= and =.+=. For example: + +#+begin_example +,** TODO Call Father + DEADLINE: <2008-02-10 Sun ++1w> + Marking this DONE shifts the date by at least one week, but also + by as many weeks as it takes to get this date into the future. + However, it stays on a Sunday, even if you called and marked it + done on Saturday. + +,** TODO Empty kitchen trash + DEADLINE: <2008-02-08 Fri 20:00 ++1d> + Marking this DONE shifts the date by at least one day, and also + by as many days as it takes to get the timestamp into the future. + Since there is a time in the timestamp, the next deadline in the + future will be on today's date if you complete the task before + 20:00. + +,** TODO Check the batteries in the smoke detectors + DEADLINE: <2005-11-01 Tue .+1m> + Marking this DONE shifts the date to one month after today. + +,** TODO Wash my hands + DEADLINE: <2019-04-05 08:00 Sun .+1h> + Marking this DONE shifts the date to exactly one hour from now. +#+end_example + +#+vindex: org-agenda-skip-scheduled-if-deadline-is-shown +You may have both scheduling and deadline information for a specific +task. If the repeater is set for the scheduling information only, you +probably want the repeater to be ignored after the deadline. If so, +set the variable ~org-agenda-skip-scheduled-if-deadline-is-shown~ to +~repeated-after-deadline~. However, any scheduling information +without a repeater is no longer relevant once the task is done, and +thus, removed upon repeating the task. If you want both scheduling +and deadline information to repeat after the same interval, set the +same repeater for both timestamps. + +An alternative to using a repeater is to create a number of copies of +a task subtree, with dates shifted in each copy.

For a specific buffer you can use: + +#+begin_example +,#+PROPERTY: Effort_ALL 0 0:10 0:30 1:00 2:00 3:00 4:00 5:00 6:00 7:00 +,#+COLUMNS: %40ITEM(Task) %17Effort(Estimated Effort){:} %CLOCKSUM +#+end_example + +#+texinfo: @noindent +#+vindex: org-global-properties +#+vindex: org-columns-default-format +or, even better, you can set up these values globally by customizing +the variables ~org-global-properties~ and +~org-columns-default-format~.

The values you enter are immediately summed up in +the hierarchy. In the column next to it, any clocked time is +displayed. + +#+vindex: org-agenda-columns-add-appointments-to-effort-sum +If you switch to column view in the daily/weekly agenda, the effort +column summarizes the estimated work effort for each day[fn:82], and +you can use this to find space in your schedule.

The properties may be real properties, or +special properties that represent other metadata (see [[*Special +Properties]]). For example, the property =TODO= represents the TODO +keyword of the entry. Or, the property =LEVEL= represents the level +of an entry. So searching =+LEVEL=3+boss-TODO​="DONE"= lists all level +three headlines that have the tag =boss= and are /not/ marked with the +TODO keyword =DONE=. In buffers with ~org-odd-levels-only~ set, +=LEVEL= does not count the number of stars, but =LEVEL=2= corresponds +to 3 stars etc. + +Here are more examples: + +- =work+TODO​="WAITING"= :: + + Select =work=-tagged TODO lines with the specific TODO keyword + =WAITING=. + +- =work+TODO​="WAITING"|home+TODO​="WAITING"= :: + + Waiting tasks both at work and at home. + +When matching properties, a number of different operators can be used +to test the value of a property. Here is a complex example: + +#+begin_example ++work-boss+PRIORITY="A"+Coffee="unlimited"+Effort<2 + +With={Sarah\|Denny}+SCHEDULED>="<2008-10-11>" +#+end_example + +#+texinfo: @noindent +The type of comparison depends on how the comparison value is written: + +- If the comparison value is a plain number, a numerical comparison is + done, and the allowed operators are =<=, ===, =>=, =<==, =>==, and + =<>=. + +- If the comparison value is enclosed in double-quotes, a string + comparison is done, and the same operators are allowed. + +- If the comparison value is enclosed in double-quotes /and/ angular + brackets (like =DEADLINE<​="<2008-12-24 18:30>"=), both values are + assumed to be date/time specifications in the standard Org way, and + the comparison is done accordingly. Valid values also include + =""= for now (including time), =""=, and =""= + for these days at 0:00 hours, i.e., without a time specification. + You can also use strings like ="<+5d>"= or ="<-2m>"= with units =d=, + =w=, =m=, and =y= for day, week, month, and year, respectively. + +- If the comparison value is enclosed in curly braces, a regexp match + is performed, with === meaning that the regexp matches the property + value, and =<>= meaning that it does not match. + +So the search string in the example finds entries tagged =work= but +not =boss=, which also have a priority value =A=, a =Coffee= property +with the value =unlimited=, an =EFFORT= property that is numerically +smaller than 2, a =With= property that is matched by the regular +expression =Sarah\|Denny=, and that are scheduled on or after October +11, 2008. + +You can configure Org mode to use property inheritance during +a search, but beware that this can slow down searches considerably. +See [[*Property Inheritance]], for details. + +For backward compatibility, and also for typing speed, there is also +a different way to test TODO states in a search. For this, terminate +the tags/property part of the search string (which may include several +terms connected with =|=) with a =/= and then specify a Boolean +expression just for TODO keywords. The syntax is then similar to that +for tags, but should be applied with care: for example, a positive +selection on several TODO keywords cannot meaningfully be combined +with boolean AND. However, /negative selection/ combined with AND can +be meaningful. To make sure that only lines are checked that actually +have any TODO keyword (resulting in a speed-up), use {{{kbd(M-x +org-agenda M)}}}, or equivalently start the TODO part after the slash +with =!=. Using {{{kbd(M-x org-agenda M)}}} or =/!= does not match +TODO keywords in a DONE state.

In these cases, the summation in the agenda + leads to incorrect results because some values count double. + +3. When the column view in the agenda shows the =CLOCKSUM= property, + that is always the entire clocked time for this item.

Set this to the symbol ~any~ if you want to + get all files in ~:base-directory~, even without extension. + +- ~:exclude~ :: + + Regular expression to match file names that should not be published, + even though they have been selected on the basis of their extension. + +- ~:include~ :: + + List of files to be included regardless of ~:base-extension~ and + ~:exclude~. + +- ~:recursive~ :: + + Non-~nil~ means, check base-directory recursively for files to + publish. + +*** Publishing action +:PROPERTIES: +:DESCRIPTION: Setting the function doing the publishing. +:END: +#+cindex: action, for publishing + +Publishing means that a file is copied to the destination directory +and possibly transformed in the process. The default transformation +is to export Org files as HTML files, and this is done by the function +~org-html-publish-to-html~ which calls the HTML exporter (see [[*HTML +Export]]). But you can also publish your content as PDF files using +~org-latex-publish-to-pdf~, or as ASCII, Texinfo, etc., using the +corresponding functions. + +If you want to publish the Org file as an =.org= file but with +/archived/, /commented/, and /tag-excluded/ trees removed, use +~org-org-publish-to-org~. This produces =file.org= and puts it in the +publishing directory. If you want a htmlized version of this file, +set the parameter ~:htmlized-source~ to ~t~. It produces +=file.org.html= in the publishing directory[fn:141]. + +Other files like images only need to be copied to the publishing +destination; for this you can use ~org-publish-attachment~. For +non-Org files, you always need to specify the publishing function: + +- ~:publishing-function~ :: + + Function executing the publication of a file. This may also be + a list of functions, which are all called in turn. + +- ~:htmlized-source~ :: + + Non-~nil~ means, publish htmlized source. + +The function must accept three arguments: a property list containing +at least a ~:publishing-directory~ property, the name of the file to +be published, and the path to the publishing directory of the output +file. It should take the specified file, make the necessary +transformation, if any, and place the result into the destination +folder. + +*** Options for the exporters +:PROPERTIES: +:DESCRIPTION: Tweaking HTML/@LaTeX{} export. +:ALT_TITLE: Publishing options +:END: +#+cindex: options, for publishing +#+cindex: publishing options + +The property list can be used to set many export options for the HTML +and LaTeX exporters.

Tramp, +while very useful and powerful, tends not to be so efficient for +multiple file transfer and has been known to cause problems under +heavy usage. + +Specialized synchronization utilities offer several advantages. In +addition to timestamp comparison, they also do content and +permissions/attribute checks. For this reason you might prefer to +publish your web to a local directory---possibly even /in place/ with +your Org files---and then use Unison or Rsync to do the +synchronization with the remote host. + +Since Unison, for example, can be configured as to which files to +transfer to a certain remote destination, it can greatly simplify the +project publishing definition. Simply keep all files in the correct +location, process your Org files with ~org-publish~ and let the +synchronization tool do the rest. You do not need, in this scenario, +to include attachments such as JPG, CSS or PNG files in the project +definition since the third-party tool syncs them. + +Publishing to a local directory is also much faster than to a remote +one, so that you can afford more easily to republish entire projects. +If you set ~org-publish-use-timestamps-flag~ to ~nil~, you gain the +main benefit of re-including any changed external files such as source +example files you might include with =INCLUDE= keyword.

Org can manage source code in an Org document +when the source code is identified with begin and end markers. +Working with source code begins with identifying source code blocks. +A source code block can be placed almost anywhere in an Org document; +it is not restricted to the preamble or the end of the document. +However, Org cannot manage a source code block if it is placed inside +an Org comment or within a fixed width section. + +Here is an example source code block in the Emacs Lisp language: + +#+begin_example +,#+BEGIN_SRC emacs-lisp + (defun org-xor (a b) + "Exclusive or." + (if a (not b) b)) +,#+END_SRC +#+end_example + +Source code blocks are one of many Org block types, which also include +"center", "comment", "dynamic", "example", "export", "quote", +"special", and "verse". This section pertains to blocks between +=#+BEGIN_SRC= and =#+END_SRC=. + +Details of Org's facilities for working with source code are described +in the following sections. + +** Features Overview +:PROPERTIES: +:DESCRIPTION: Enjoy the versatility of source blocks. +:END: + +Org can manage the source code in the block delimited by =#+BEGIN_SRC= +... =#+END_SRC= in several ways that can simplify housekeeping tasks +essential to modern source code maintenance. Org can edit, format, +extract, export, and publish source code blocks. Org can also compile +and execute a source code block, then capture the results. The Org +mode literature sometimes refers to source code blocks as /live code/ +blocks because they can alter the content of the Org document or the +material that it exports. Users can control the "liveliness" of each +source code block by tweaking the header arguments (see [[*Using Header +Arguments]]) for compiling, execution, extraction, and exporting. + +For editing and formatting a source code block, Org uses an +appropriate Emacs major mode that includes features specifically +designed for source code in that language. + +Org can extract one or more source code blocks and write them to one +or more source files---a process known as /tangling/ in literate +programming terminology. + +For exporting and publishing, Org's back-ends can format a source code +block appropriately, often with native syntax highlighting. + +For executing and compiling a source code block, the user can +configure Org to select the appropriate compiler. Org provides +facilities to collect the result of the execution or compiler output, +insert it into the Org document, and/or export it. In addition to +text results, Org can insert links to other data types, including +audio, video, and graphics. Org can also link a compiler error +message to the appropriate line in the source code block. + +An important feature of Org's management of source code blocks is the +ability to pass variables, functions, and results to one another using +a common syntax for source code blocks in any language. Although most +literate programming facilities are restricted to one language or +another, Org's language-agnostic approach lets the literate programmer +match each programming task with the appropriate computer language and +to mix them all together in a single Org document. This +interoperability among languages explains why Org's source code +management facility was named /Org Babel/ by its originators, Eric +Schulte and Dan Davison. + +Org mode fulfills the promise of easy verification and maintenance of +publishing reproducible research by keeping text, data, code, +configuration settings of the execution environment, the results of +the execution, and associated narratives, claims, references, and +internal and external links in a single Org document. + +** Structure of Code Blocks +:PROPERTIES: +:DESCRIPTION: Code block syntax described. +:END: +#+cindex: code block, structure +#+cindex: source code, block structure +#+cindex: @samp{NAME} keyword, in source blocks +#+cindex: @samp{BEGIN_SRC} + +Org offers two ways to structure source code in Org documents: in +a source code block, and directly inline.

I was trying to organize my notes and +projects, and using Emacs seemed to be the natural way to go. +However, having to remember eleven different commands with two or +three keys per command, only to hide and show parts of the outline +tree, that seemed entirely unacceptable to me. Also, when using +outlines to take notes, I constantly wanted to restructure the tree, +organizing it parallel to my thoughts and plans. /Visibility cycling/ +and /structure editing/ were originally implemented in the package +=outline-magic.el=, but quickly moved to the more general =org.el=. +As this environment became comfortable for project planning, the next +step was adding /TODO entries/, basic /timestamps/, and /table +support/. These areas highlighted the two main goals that Org still +has today: to be a new, outline-based, plain text mode with innovative +and intuitive editing features, and to incorporate project planning +functionality directly into a notes file. + +Since the first release, literally thousands of emails to me or to the +[[mailto:emacs-orgmode@gnu.org][mailing list]] have provided a constant stream of bug reports, feedback, +new ideas, and sometimes patches and add-on code. Many thanks to +everyone who has helped to improve this package. I am trying to keep +here a list of the people who had significant influence in shaping one +or more aspects of Org. The list may not be complete, if I have +forgotten someone, please accept my apologies and let me know. + +Before I get to this list, a few special mentions are in order: + +- Bastien Guerry :: + + Bastien has written a large number of extensions to Org (most of + them integrated into the core by now), including the LaTeX exporter + and the plain list parser. His support during the early days was + central to the success of this project. Bastien also invented Worg, + helped establishing the Web presence of Org, and sponsored hosting + costs for the orgmode.org website. Bastien stepped in as maintainer + of Org between 2011 and 2013, at a time when I desperately needed + a break. + +- Eric Schulte and Dan Davison :: + + Eric and Dan are jointly responsible for the Org Babel system, which + turns Org into a multi-language environment for evaluating code and + doing literate programming and reproducible research. This has + become one of Org's killer features that define what Org is today. + +- John Wiegley :: + + John has contributed a number of great ideas and patches directly to + Org, including the attachment system (=org-attach.el=), integration + with Apple Mail (=org-mac-message.el=), hierarchical dependencies of + TODO items, habit tracking (=org-habits.el=), and encryption + (=org-crypt.el=). Also, the capture system is really an extended + copy of his great =remember.el=. + +- Sebastian Rose :: + + Without Sebastian, the HTML/XHTML publishing of Org would be the + pitiful work of an ignorant amateur. Sebastian has pushed this part + of Org onto a much higher level. He also wrote =org-info.js=, + a JavaScript program for displaying webpages derived from Org using + an Info-like or a folding interface with single-key navigation. + +See below for the full list of contributions!

His unremitting support is what really helped +me getting more confident over time, with both the community and the +code. + +When I took over maintainership, I knew I would have to make Org more +collaborative than ever, as I would have to rely on people that are +more knowledgeable than I am on many parts of the code. Here is +a list of the persons I could rely on, they should really be +considered co-maintainers, either of the code or the community: + +- Eric Schulte :: + + Eric is maintaining the Babel parts of Org. His reactivity here + kept me away from worrying about possible bugs here and let me focus + on other parts. + +- Nicolas Goaziou :: + + Nicolas is maintaining the consistency of the deepest parts of Org. + His work on =org-element.el= and =ox.el= has been outstanding, and + it opened the doors for many new ideas and features. He rewrote + many of the old exporters to use the new export engine, and helped + with documenting this major change. More importantly (if that's + possible), he has been more than reliable during all the work done + for Org 8.0, and always very reactive on the mailing list. + +- Achim Gratz :: + + Achim rewrote the building process of Org, turning some /ad hoc/ + tools into a flexible and conceptually clean process. He patiently + coped with the many hiccups that such a change can create for users. + +- Nick Dokos :: + + The Org mode mailing list would not be such a nice place without + Nick, who patiently helped users so many times. It is impossible to + overestimate such a great help, and the list would not be so active + without him. + +I received support from so many users that it is clearly impossible to +be fair when shortlisting a few of them, but Org's history would not +be complete if the ones above were not mentioned in this manual. + +** List of Contributions +:PROPERTIES: +:UNNUMBERED: notoc +:END: + +- Russell Adams came up with the idea for drawers. + +- Thomas Baumann wrote =ol-bbdb.el= and =ol-mhe.el=. + +- Christophe Bataillon created the great unicorn logo that we use on + the Org mode website. + +- Alex Bochannek provided a patch for rounding timestamps. + +- Jan Böcker wrote =ol-docview.el=. + +- Brad Bozarth showed how to pull RSS feed data into Org files. + +- Tom Breton wrote =org-choose.el=. + +- Charles Cave's suggestion sparked the implementation of templates + for Remember, which are now templates for capture. + +- Timothy E Chapman worked on a complete overhaul of the orgmode.org + website in 2020 and helped fixing various bugs. + +- Pavel Chalmoviansky influenced the agenda treatment of items with + specified time. + +- Gregory Chernov patched support for Lisp forms into table + calculations and improved XEmacs compatibility, in particular by + porting =nouline.el= to XEmacs. + +- Sacha Chua suggested copying some linking code from Planner. + +- Baoqiu Cui contributed the DocBook exporter. + +- Eddward DeVilla proposed and tested checkbox statistics. He also + came up with the idea of properties, and that there should be an API + for them. + +- Nick Dokos tracked down several nasty bugs. + +- Kees Dullemond used to edit projects lists directly in HTML and so + inspired some of the early development, including HTML export.

Note +also that clocking only works with headings indented less than 30 +stars. + +[fn:4] See, however, the option ~org-cycle-emulate-tab~. + +[fn:5] The indirect buffer contains the entire buffer, but is narrowed +to the current tree. Editing the indirect buffer also changes the +original buffer, but without affecting visibility in that buffer. For +more information about indirect buffers, see [[info:emacs#Indirect Buffers][GNU Emacs Manual]]. + +[fn:6] When ~org-agenda-inhibit-startup~ is non-~nil~, Org does not +honor the default visibility state when first opening a file for the +agenda (see [[*Speeding Up Your Agendas]]). + +[fn:7] See also the variable ~org-show-context-detail~ to decide how +much context is shown around each match. + +[fn:8] This depends on the option ~org-remove-highlights-with-change~. + +[fn:9] When using =*= as a bullet, lines must be indented so that they +are not interpreted as headlines. Also, when you are hiding leading +stars to get a clean outline view, plain list items starting with +a star may be hard to distinguish from true headlines. In short: even +though =*= is supported, it may be better to not use it for plain list +items. + +[fn:10] You can filter out any of them by configuring +~org-plain-list-ordered-item-terminator~. + +[fn:11] You can also get =a.=, =A.=, =a)= and =A)= by configuring +~org-list-allow-alphabetical~. To minimize confusion with normal +text, those are limited to one character only. Beyond that limit, +bullets automatically become numbers. + +[fn:12] If there's a checkbox in the item, the cookie must be put +/before/ the checkbox. If you have activated alphabetical lists, you +can also use counters like =[@b]=. + +[fn:13] If you do not want the item to be split, customize the +variable ~org-M-RET-may-split-line~. + +[fn:14] If you want to cycle around items that way, you may customize +~org-list-use-circular-motion~. + +[fn:15] See ~org-list-use-circular-motion~ for a cyclic behavior. + +[fn:16] Many desktops intercept {{{kbd(M-TAB)}}} to switch windows. +Use {{{kbd(C-M-i)}}} or {{{kbd(ESC TAB)}}} instead. + +[fn:17] To insert a vertical bar into a table field, use =\vert= or, +inside a word =abc\vert{}def=. + +[fn:18] Org understands references typed by the user as =B4=, but it +does not use this syntax when offering a formula for editing. You can +customize this behavior using the variable +~org-table-use-standard-references~. + +[fn:19] The computation time scales as O(N^2) because table +{{{var(FOO)}}} is parsed for each field to be copied. + +[fn:20] The file =constants.el= can supply the values of constants in +two different unit systems, =SI= and =cgs=. Which one is used depends +on the value of the variable ~constants-unit-system~. You can use the +=STARTUP= options =constSI= and =constcgs= to set this value for the +current buffer. + +[fn:21] The printf reformatting is limited in precision because the +value passed to it is converted into an "integer" or "double". The +"integer" is limited in size by truncating the signed value to 32 +bits. The "double" is limited in precision to 64 bits overall which +leaves approximately 16 significant decimal digits. + +[fn:22] Such names must start with an alphabetic character and use +only alphanumeric/underscore characters. + +[fn:23] Plain URIs are recognized only for a well-defined set of +schemes. See [[*External Links]]. Unlike URI syntax, they cannot contain +parenthesis or white spaces, either. URIs within angle brackets have +no such limitation. + +[fn:24] More accurately, the precise behavior depends on how point +arrived there---see [[info:elisp#Invisible Text][Invisible Text]]. + +[fn:25] To insert a link targeting a headline, in-buffer completion +can be used. Just type a star followed by a few optional letters into +the buffer and press {{{kbd(M-TAB)}}}. All headlines in the current +buffer are offered as completions. + +[fn:26] When targeting a =NAME= keyword, the =CAPTION= keyword is +mandatory in order to get proper numbering (see [[*Captions]]). + +[fn:27] The actual behavior of the search depends on the value of the +variable ~org-link-search-must-match-exact-headline~. If its value is +~nil~, then a fuzzy text search is done. If it is ~t~, then only the +exact headline is matched, ignoring spaces and statistic cookies. If +the value is ~query-to-create~, then an exact headline is searched; if +it is not found, then the user is queried to create it. + +[fn:28] If the headline contains a timestamp, it is removed from the +link, which results in a wrong link---you should avoid putting +a timestamp in the headline. + +[fn:29] The Org Id library must first be loaded, either through +~org-customize~, by enabling ~id~ in ~org-modules~, or by adding +=(require 'org-id)= in your Emacs init file. + +[fn:30] Note that you do not have to use this command to insert +a link. Links in Org are plain text, and you can type or paste them +straight into the buffer. By using this command, the links are +automatically enclosed in double brackets, and you will be asked for +the optional descriptive text. + +[fn:31] After insertion of a stored link, the link will be removed +from the list of stored links. To keep it in the list for later use, +use a triple {{{kbd(C-u)}}} prefix argument to {{{kbd(C-c C-l)}}}, or +configure the option ~org-link-keep-stored-after-insertion~. + +[fn:32] This works if a function has been defined in the ~:complete~ +property of a link in ~org-link-parameters~. + +[fn:33] See the variable ~org-link-use-indirect-buffer-for-internals~. + +[fn:34] For backward compatibility, line numbers can also follow a +single colon. + +[fn:35] Of course, you can make a document that contains only long +lists of TODO items, but this is not required. + +[fn:36] Changing the variable ~org-todo-keywords~ only becomes +effective after restarting Org mode in a buffer. + +[fn:37] This is also true for the {{{kbd(t)}}} command in the agenda +buffer. + +[fn:38] All characters are allowed except =@=, =^= and =!=, which have +a special meaning here. + +[fn:39] Check also the variable ~org-fast-tag-selection-include-todo~, +it allows you to change the TODO state through the tags interface (see +[[*Setting Tags]]), in case you like to mingle the two concepts. Note +that this means you need to come up with unique keys across both sets +of keywords. + +[fn:40] Org mode parses these lines only when Org mode is activated +after visiting a file. {{{kbd(C-c C-c)}}} with point in a line +starting with =#+= is simply restarting Org mode for the current +buffer. + +[fn:41] The corresponding in-buffer setting is: =#+STARTUP: logdone=. + +[fn:42] The corresponding in-buffer setting is: =#+STARTUP: +lognotedone=. + +[fn:43] See the variable ~org-log-states-order-reversed~. + +[fn:44] Note that the =LOGBOOK= drawer is unfolded when pressing +{{{kbd(SPC)}}} in the agenda to show an entry---use {{{kbd(C-u +SPC)}}} to keep it folded here. + +[fn:45] It is possible that Org mode records two timestamps when you +are using both ~org-log-done~ and state change logging. However, it +never prompts for two notes: if you have configured both, the state +change recording note takes precedence and cancel the closing note. + +[fn:46] See also the option ~org-priority-start-cycle-with-default~. + +[fn:47] To keep subtasks out of the global TODO list, see the option +~org-agenda-todo-list-sublevels~. + +[fn:48] With the exception of description lists. But you can allow it +by modifying ~org-list-automatic-rules~ accordingly. + +[fn:49] Set the variable ~org-hierarchical-checkbox-statistics~ if you +want such cookies to count all checkboxes below the cookie, not just +those belonging to direct children. + +[fn:50] {{{kbd(C-u C-c C-c)}}} on the /first/ item of a list with no +checkbox adds checkboxes to the rest of the list. + +[fn:51] As with all these in-buffer settings, pressing {{{kbd(C-c +C-c)}}} activates any changes in the line. + +[fn:52] This is only true if the search does not involve more complex +tests including properties (see [[*Property Searches]]). + +[fn:53] To extend this default list to all tags used in all agenda +files (see [[*Agenda Views]]), customize the variable +~org-complete-tags-always-offer-all-agenda-tags~. + +[fn:54] Keys are automatically assigned to tags that have no +configured keys. + +[fn:55] If more than one summary type applies to the same property, +the parent values are computed according to the first of them. + +[fn:56] An age can be defined as a duration, using units defined in +~org-duration-units~, e.g., =3d 1h=. If any value in the column is as +such, the summary is also expressed as a duration. + +[fn:57] Please note that the =COLUMNS= definition must be on a single +line; it is wrapped here only because of formatting constraints. + +[fn:58] Contributed packages are not part of Emacs, but are +distributed with the main distribution of Org---visit +[[https://orgmode.org]]. + +[fn:59] The Org date format is inspired by the standard ISO 8601 +date/time format. To use an alternative format, see [[*Custom time +format]]. The day name is optional when you type the date yourself. +However, any date inserted or modified by Org adds that day name, for +reading convenience. + +[fn:60] When working with the standard diary expression functions, you +need to be very careful with the order of the arguments. That order +depends evilly on the variable ~calendar-date-style~. For example, to +specify a date December 12, 2005, the call might look like +=(diary-date 12 1 2005)= or =(diary-date 1 12 2005)= or =(diary-date +2005 12 1)=, depending on the settings. This has been the source of +much confusion. Org mode users can resort to special versions of +these functions like ~org-date~ or ~org-anniversary~. These work just +like the corresponding ~diary-~ functions, but with stable ISO order +of arguments (year, month, day) wherever applicable, independent of +the value of ~calendar-date-style~. + +[fn:61] See the variable ~org-read-date-prefer-future~. You may set +that variable to the symbol ~time~ to even make a time before now +shift the date to tomorrow. + +[fn:62] If you do not need/want the calendar, configure the variable +~org-popup-calendar-for-date-prompt~. + +[fn:63] You can also use the calendar command {{{kbd(.)}}} to jump to +today's date, but if you are inserting an hour specification for your +timestamp, {{{kbd(.)}}} will then insert a dot after the hour. By contrast, +{{{kbd(C-.)}}} will always jump to today's date. + +[fn:64] If you find this distracting, turn off the display with +~org-read-date-display-live~. + +[fn:65] It will still be listed on that date after it has been marked +as done. If you do not like this, set the variable +~org-agenda-skip-scheduled-if-done~. + +[fn:66] The =SCHEDULED= and =DEADLINE= dates are inserted on the line +right below the headline. Do not put any text between this line and +the headline. + +[fn:67] Note the corresponding =STARTUP= options =logredeadline=, +=lognoteredeadline=, and =nologredeadline=. + +[fn:68] Note the corresponding =STARTUP= options =logreschedule=, +=lognotereschedule=, and =nologreschedule=. + +[fn:69] Org does not repeat inactive timestamps, however. See +[[*Timestamps]]. + +[fn:70] In fact, the target state is taken from, in this sequence, the +=REPEAT_TO_STATE= property, the variable ~org-todo-repeat-to-state~ if +it is a string, the previous TODO state if ~org-todo-repeat-to-state~ +is ~t~, or the first state of the TODO state sequence. + +[fn:71] You can change this using the option ~org-log-repeat~, or the +=STARTUP= options =logrepeat=, =lognoterepeat=, and =nologrepeat=. +With =lognoterepeat=, you will also be prompted for a note. + +[fn:72] Clocking only works if all headings are indented with less +than 30 stars. This is a hard-coded limitation of ~lmax~ in +~org-clock-sum~. + +[fn:73] To resume the clock under the assumption that you have worked +on this task while outside Emacs, use =(setq org-clock-persist t)=. + +[fn:74] To add an effort estimate "on the fly", hook a function doing +this to ~org-clock-in-prepare-hook~. + +[fn:75] The last reset of the task is recorded by the =LAST_REPEAT= +property. + +[fn:76] See also the variable ~org-clock-mode-line-total~. + +[fn:77] The corresponding in-buffer setting is: =#+STARTUP: +lognoteclock-out=. + +[fn:78] When using ~:step~, ~untilnow~ starts from the beginning of +2003, not the beginning of time. + +[fn:79] Language terms can be set through the variable +~org-clock-clocktable-language-setup~. + +[fn:80] Note that all parameters must be specified in a single +line---the line is broken here only to fit it into the manual. + +[fn:81] On computers using macOS, idleness is based on actual user +idleness, not just Emacs' idle time. For X11, you can install a +utility program =x11idle.c=, available in the =org-contrib/= +repository, or install the xprintidle package and set it to the +variable ~org-clock-x11idle-program-name~ if you are running Debian, +to get the same general treatment of idleness. On other systems, idle +time refers to Emacs idle time only. + +[fn:82] Please note the pitfalls of summing hierarchical data in +a flat list (see [[*Using Column View in the Agenda]]). + +[fn:83] Note the corresponding =STARTUP= options =logrefile=, +=lognoterefile=, and =nologrefile=. + +[fn:84] Org used to offer four different targets for date/week tree +capture. Now, Org automatically translates these to use +~file+olp+datetree~, applying the ~:time-prompt~ and ~:tree-type~ +properties. Please rewrite your date/week-tree targets using +~file+olp+datetree~ since the older targets are now deprecated. + +[fn:85] A date tree is an outline structure with years on the highest +level, months or ISO weeks as sublevels and then dates on the lowest +level. Tags are allowed in the tree structure. + +[fn:86] When the file name is not absolute, Org assumes it is relative +to ~org-directory~. + +[fn:87] If you need one of these sequences literally, escape the =%= +with a backslash. + +[fn:88] If you define your own link types (see [[*Adding Hyperlink +Types]]), any property you store with ~org-store-link-props~ can be +accessed in capture templates in a similar way. + +[fn:89] This is always the other, not the user. See the variable +~org-link-from-user-regexp~. + +[fn:90] If you move entries or Org files from one directory to +another, you may want to configure ~org-attach-id-dir~ to contain +an absolute path. + +[fn:91] If the value of that variable is not a list, but a single file +name, then the list of agenda files in maintained in that external +file. + +[fn:92] When using the dispatcher, pressing {{{kbd(<)}}} before +selecting a command actually limits the command to the current file, +and ignores ~org-agenda-files~ until the next dispatcher command. + +[fn:93] For backward compatibility, you can also press {{{kbd(1)}}} to +restrict to the current buffer. + +[fn:94] For backward compatibility, you can also press {{{kbd(0)}}} to +restrict to the current region/subtree. + +[fn:95] For backward compatibility, the universal prefix argument +{{{kbd(C-u)}}} causes all TODO entries to be listed before the agenda. +This feature is deprecated, use the dedicated TODO list, or a block +agenda instead (see [[*Block agenda]]). + +[fn:96] The variable ~org-anniversary~ used in the example is just +like ~diary-anniversary~, but the argument order is always according +to ISO and therefore independent of the value of +~calendar-date-style~. + +[fn:97] You can, however, disable this by setting +~org-agenda-search-headline-for-time~ variable to a ~nil~ value. + +[fn:98] Custom agenda commands can preset a filter by binding one of +the variables ~org-agenda-tag-filter-preset~, +~org-agenda-category-filter-preset~, ~org-agenda-effort-filter-preset~ +or ~org-agenda-regexp-filter-preset~ as an option. This filter is +then applied to the view and persists as a basic filter through +refreshes and more secondary filtering. The filter is a global +property of the entire agenda view---in a block agenda, you should +only set this in the global options section, not in the section of an +individual block. + +[fn:99] Only tags filtering is respected here, effort filtering is +ignored. + +[fn:100] You can also create persistent custom functions through +~org-agenda-bulk-custom-functions~. + +[fn:101] This file is parsed for the agenda when +~org-agenda-include-diary~ is set. + +[fn:102] You can provide a description for a prefix key by inserting +a cons cell with the prefix and the description. + +[fn:103] /Planned/ means here that these entries have some planning +information attached to them, like a time-stamp, a scheduled or +a deadline string. See ~org-agenda-entry-types~ on how to set what +planning information is taken into account. + +[fn:104] For HTML you need to install Hrvoje Nikšić's =htmlize.el= +as an Emacs package from MELPA or from [[https://github.com/hniksic/emacs-htmlize][Hrvoje Nikšić's repository]]. + +[fn:105] To create PDF output, the Ghostscript ps2pdf utility must be +installed on the system. Selecting a PDF file also creates the +postscript file. + +[fn:106] If you want to store standard views like the weekly agenda or +the global TODO list as well, you need to define custom commands for +them in order to be able to specify file names. + +[fn:107] Quoting depends on the system you use, please check the FAQ +for examples. + +[fn:108] You can turn this on by default by setting the variable +~org-pretty-entities~, or on a per-file base with the =STARTUP= option +=entitiespretty=. + +[fn:109] This behavior can be disabled with =-= export setting (see +[[*Export Settings]]). + +[fn:110] LaTeX is a macro system based on Donald\nbsp{}E.\nbsp{}Knuth's TeX +system. Many of the features described here as "LaTeX" are really +from TeX, but for simplicity I am blurring this distinction. + +[fn:111] When MathJax is used, only the environments recognized by +MathJax are processed. When dvipng, dvisvgm, or ImageMagick suite is +used to create images, any LaTeX environment is handled. + +[fn:112] These are respectively available at +[[http://sourceforge.net/projects/dvipng/]], [[http://dvisvgm.bplaced.net/]] +and from the ImageMagick suite. Choose the converter by setting the +variable ~org-preview-latex-default-process~ accordingly. + +[fn:113] Org mode has a method to test if point is inside such +a fragment, see the documentation of the function +~org-inside-LaTeX-fragment-p~. + +[fn:114] This works automatically for the HTML backend (it requires +version 1.34 of the =htmlize.el= package, which you need to install). +Fontified code chunks in LaTeX can be achieved using either the +[[https://www.ctan.org/pkg/listings][listings]] package or the [[https://www.ctan.org/pkg/minted][minted]] package. Refer to +~org-latex-listings~ for details. + +[fn:115] Source code in code blocks may also be evaluated either +interactively or on export. See [[*Working with Source Code]] for more +information on evaluating code blocks. + +[fn:116] Adding =-k= to =-n -r= /keeps/ the labels in the source code +while using line numbers for the links, which might be useful to +explain those in an Org mode example code. + +[fn:117] You may select a different mode with the variable +~org-edit-fixed-width-region-mode~. + +[fn:118] What Emacs considers to be an image depends on +~image-file-name-extensions~ and ~image-file-name-regexps~. + +[fn:119] The variable ~org-startup-with-inline-images~ can be set +within a buffer with the =STARTUP= options =inlineimages= and +=noinlineimages=. + +[fn:120] The corresponding in-buffer setting is: =#+STARTUP: fninline= +or =#+STARTUP: nofninline=. + +[fn:121] The corresponding in-buffer options are =#+STARTUP: fnadjust= +and =#+STARTUP: nofnadjust=. + +[fn:122] The variable ~org-export-date-timestamp-format~ defines how +this timestamp are exported. + +[fn:123] For export to LaTeX format---or LaTeX-related formats such as +Beamer---, the =org-latex-package-alist= variable needs further +configuration. See [[LaTeX specific export settings]]. + +[fn:124] At the moment, some export back-ends do not obey this +specification. For example, LaTeX export excludes every unnumbered +headline from the table of contents. + +[fn:125] Note that ~org-link-search-must-match-exact-headline~ is +locally bound to non-~nil~. Therefore, ~org-link-search~ only matches +headlines and named elements. + +[fn:126] Since commas separate the arguments, commas within arguments +have to be escaped with the backslash character. So only those +backslash characters before a comma need escaping with another +backslash character. + +[fn:127] For a less drastic behavior, consider using a select tag (see +[[*Export Settings]]) instead. + +[fn:128] If =BEAMER_ENV= is set, Org export adds =B_environment= tag +to make it visible. The tag serves as a visual aid and has no +semantic relevance. + +[fn:129] By default Org loads MathJax from [[https://cdnjs.com][cdnjs.com]] as recommended by +[[https://www.mathjax.org][MathJax]]. + +[fn:130] Please note that exported formulas are part of an HTML +document, and that signs such as =<=, =>=, or =&= have special +meanings. See [[http://docs.mathjax.org/en/latest/tex.html#tex-and-latex-in-html-documents][MathJax TeX and LaTeX support]]. + +[fn:131] See [[http://docs.mathjax.org/en/latest/tex.html#tex-extensions][TeX and LaTeX extensions]] in the [[http://docs.mathjax.org][MathJax manual]] to learn +about extensions. + +[fn:132] If the classes on TODO keywords and tags lead to conflicts, +use the variables ~org-html-todo-kwd-class-prefix~ and +~org-html-tag-class-prefix~ to make them unique. + +[fn:133] This does not allow setting different bibliography compilers +for different files. However, "smart" LaTeX compilation systems, such +as latexmk, can select the correct bibliography compiler. + +[fn:134] Minted uses an external Python package for code highlighting, +which requires the flag =-shell-escape= to be added to +~org-latex-pdf-process~. + +[fn:135] See [[http://docs.oasis-open.org/office/v1.2/OpenDocument-v1.2.html][Open Document Format for Office Applications +(OpenDocument) Version 1.2]]. + +[fn:136] See [[http://www.mathtoweb.com/cgi-bin/mathtoweb_home.pl][MathToWeb]]. + +[fn:137] See [[http://dlmf.nist.gov/LaTeXML/]]. + +[fn:138] [[http://docs.oasis-open.org/office/v1.2/OpenDocument-v1.2.html][OpenDocument-v1.2 Specification]] + +[fn:139] See the == element of the +OpenDocument-v1.2 specification. + +[fn:140] See the attributes =table:template-name=, +=table:use-first-row-styles=, =table:use-last-row-styles=, +=table:use-first-column-styles=, =table:use-last-column-styles=, +=table:use-banding-rows-styles=, and =table:use-banding-column-styles= +of the == element in the OpenDocument-v1.2 specification. + +[fn:141] If the publishing directory is the same as the source +directory, =file.org= is exported as =file.org.org=, so you probably +do not want to do this. + +[fn:142] The option ~org-babel-no-eval-on-ctrl-c-ctrl-c~ can be used +to remove code evaluation from the {{{kbd(C-c C-c)}}} key binding. + +[fn:143] Actually, the constructs =call_()= and =src_{}= +are not evaluated when they appear in a keyword (see [[*Summary of +In-Buffer Settings]]). + +[fn:144] For noweb literate programming details, see +http://www.cs.tufts.edu/~nr/noweb/. + +[fn:145] For more information, please refer to the commentary section +in =org-tempo.el=. + +[fn:146] Org Indent mode also sets ~wrap-prefix~ correctly for +indenting and wrapping long lines of headlines or text. This minor +mode also handles Visual Line mode and directly applied settings +through ~word-wrap~. + +[fn:147] This works, but requires extra effort. Org Indent mode is +more convenient for most applications. + +[fn:148] ~org-adapt-indentation~ can also be set to ='headline-data=, +in which case only data lines below the headline will be indented. + +[fn:149] Note that Org Indent mode also sets the ~wrap-prefix~ +property, such that Visual Line mode (or purely setting ~word-wrap~) +wraps long lines, including headlines, correctly indented. + +[fn:150] For a server to host files, consider using a WebDAV server, +such as [[https://nextcloud.com][Nextcloud]]. Additional help is at this [[https://orgmode.org/worg/org-faq.html#mobileorg_webdav][FAQ entry]]. + +[fn:151] If Emacs is configured for safe storing of passwords, then +configure the variable ~org-mobile-encryption-password~; please read +the docstring of that variable. + +[fn:152] Symbolic links in ~org-directory~ need to have the same name +as their targets. + +[fn:153] While creating the agendas, Org mode forces =ID= properties +on all referenced entries, so that these entries can be uniquely +identified if Org Mobile flags them for further action. To avoid +setting properties configure the variable +~org-mobile-force-id-on-agenda-items~ to ~nil~. Org mode then relies +on outline paths, assuming they are unique. + +[fn:154] Checksums are stored automatically in the file +=checksums.dat=. + +[fn:155] The file will be empty after this operation. + +[fn:156] https://www.ctan.org/pkg/comment + +[fn:157] By default this works only for LaTeX, HTML, and Texinfo. +Configure the variable ~orgtbl-radio-table-templates~ to install +templates for other modes. + +[fn:158] If the =TBLFM= keyword contains an odd number of dollar +characters, this may cause problems with Font Lock in LaTeX mode. As +shown in the example you can fix this by adding an extra line inside +the =comment= environment that is used to balance the dollar +expressions. If you are using AUCTeX with the font-latex library, +a much better solution is to add the =comment= environment to the +variable ~LaTeX-verbatim-environments~. + +[fn:159] The ~agenda*~ view is the same as ~agenda~ except that it +only considers /appointments/, i.e., scheduled and deadline items that +have a time specification =[h]h:mm= in their time-stamps. + +[fn:160] Note that, for ~org-odd-levels-only~, a level number +corresponds to order in the hierarchy, not to the number of stars. diff --git a/elpa/org-9.5.2/doc/org-version.inc b/elpa/org-9.5.2/doc/org-version.inc new file mode 100644 index 0000000..22fb34e --- /dev/null +++ b/elpa/org-9.5.2/doc/org-version.inc @@ -0,0 +1,3 @@ +@c automatically generated, do not edit +@set VERSION 9.5.2 (9.5.2-gfbff08) +@set DATE 2021-12-24 diff --git a/elpa/org-9.5.2/doc/org.texi b/elpa/org-9.5.2/doc/org.texi new file mode 100644 index 0000000..a196989 --- /dev/null +++ b/elpa/org-9.5.2/doc/org.texi @@ -0,0 +1,23491 @@ +\input texinfo @c -*- texinfo -*- +@c %**start of header +@setfilename org.info +@settitle The Org Manual +@documentencoding UTF-8 +@documentlanguage en +@set txicodequoteundirected +@set txicodequotebacktick +@set MAINTAINERSITE @uref{https://orgmode.org,maintainers webpage} +@set MAINTAINER Bastien Guerry +@set MAINTAINEREMAIL @email{bzg@gnu.org} +@set MAINTAINERCONTACT @uref{mailto:bzg@gnu.org,contact the maintainer} +@c %**end of header + +@copying +This manual is for Org version 9.5. + +Copyright @copyright{} 2004--2021 Free Software Foundation, Inc. + +@quotation +Permission is granted to copy, distribute and/or modify this document +under the terms of the GNU Free Documentation License, Version 1.3 or +any later version published by the Free Software Foundation; with no +Invariant Sections, with the Front-Cover Texts being ``A GNU Manual,'' +and with the Back-Cover Texts as in (a) below.

maintaining TODO lists, and project +planning with a fast and effective plain-text markup language. It +also is an authoring system with unique support for literate +programming and reproducible research. + +Org is implemented on top of Outline mode, which makes it possible to +keep the content of large files well structured. Visibility cycling +and structure editing help to work with the tree. Tables are easily +created with a built-in table editor. Plain text URL-like links +connect to websites, emails, Usenet messages, BBDB entries, and any +files related to the projects. + +Org develops organizational tasks around notes files that contain +lists or information about projects as plain text. Project planning +and task management make use of metadata which is part of an outline +node. Based on this data, specific entries can be extracted in +queries and create dynamic @emph{agenda views} that also integrate the +Emacs calendar and diary. Org can be used to implement many different +project planning schemes, such as David Allen's GTD system. + +Org files can serve as a single source authoring system with export to +many different formats such as HTML, @LaTeX{}, Open Document, and +Markdown. New export backends can be derived from existing ones, or +defined from scratch. + +Org files can include source code blocks, which makes Org uniquely +suited for authoring technical documents with code examples. Org +source code blocks are fully functional; they can be evaluated in +place and their results can be captured in the file. This makes it +possible to create a single file reproducible research compendium. + +Org keeps simple things simple. When first fired up, it should feel +like a straightforward, easy to use outliner. Complexity is not +imposed, but a large amount of functionality is available when needed. +Org is a toolbox. Many users actually run only a---very +personal---fraction of Org's capabilities, and know that there is more +whenever they need it. + +All of this is achieved with strictly plain text files, the most +portable and future-proof file format. Org runs in Emacs. Emacs is +one of the most widely ported programs, so that Org mode is available +on every major platform. + +@cindex FAQ +There is a website for Org which provides links to the newest version +of Org, as well as additional information, frequently asked questions +(FAQ), links to tutorials, etc. This page is located at +@uref{https://orgmode.org}. + +@cindex print edition +An earlier version (7.3) of this manual is available as a @uref{http://www.network-theory.co.uk/org/manual/, paperback +book from Network Theory Ltd.}. + +@node Installation +@section Installation + +@cindex installation + +Org is included in all recent distributions of GNU Emacs, so you +probably do not need to install it. Most users will simply activate +Org and begin exploring its many features. + +If, for one reason or another, you want to install Org on top of this +pre-packaged version, you can use the Emacs package system or clone +Org's git repository. + +We @strong{strongly recommend} sticking to a single installation method. + +@anchor{Using Emacs packaging system} +@subheading Using Emacs packaging system + +Recent Emacs distributions include a packaging system which lets you +install Elisp libraries.

If you are not sending the Email +from within Emacs, please copy and paste the content into your Email +program. + +Sometimes you might face a problem due to an error in your Emacs or +Org mode setup. Before reporting a bug, it is very helpful to start +Emacs with minimal customizations and reproduce the problem. Doing so +often helps you determine if the problem is with your customization or +with Org mode itself. You can start a typical minimal session with +a command like the example below. + +@example +$ emacs -Q -l /path/to/minimal-org.el +@end example + + +However if you are using Org mode as distributed with Emacs, a minimal +setup is not necessary.

The best way to report this is by +providing, in addition to what was mentioned above, a backtrace. This +is information from the built-in debugger about where and how the +error occurred. Here is how to produce a useful backtrace: + +@enumerate +@item +Reload uncompiled versions of all Org mode Lisp files. The +backtrace contains much more information if it is produced with +uncompiled code. To do this, use + +@example +C-u M-x org-reload +@end example + + +@noindent +or, from the menu: Org @arrow{} Refresh/Reload @arrow{} Reload Org uncompiled. + +@item +Then, activate the debugger: + +@example +M-x toggle-debug-on-error +@end example + + +@noindent +or, from the menu: Options @arrow{} Enter Debugger on Error. + +@item +Do whatever you have to do to hit the error. Do not forget to +document the steps you take. + +@item +When you hit the error, a @samp{*Backtrace*} buffer appears on the +screen. Save this buffer to a file---for example using @kbd{C-x C-w}---and attach it to your bug report. +@end enumerate + +@node Conventions +@section Typesetting Conventions Used in this Manual + + + +@anchor{TODO keywords tags properties etc} +@subheading TODO keywords, tags, properties, etc. + +Org uses various syntactical elements: TODO keywords, tags, property +names, keywords, blocks, etc. In this manual we use the following +conventions: + +@table @asis +@item @samp{TODO} +@itemx @samp{WAITING} +TODO keywords are written with all capitals, even if they are +user-defined. + +@item @samp{boss} +@itemx @samp{ARCHIVE} +Tags are case-sensitive.

Org mode often uses the same key for +different functions, depending on context. The command that is bound +to such keys has a generic name, like @code{org-metaright}. In the manual +we will, wherever possible, give the function that is internally +called by the generic command. For example, in the chapter on +document structure, @kbd{M-@key{RIGHT}} will be listed to call +@code{org-do-demote}, while in the chapter on tables, it will be listed to +call @code{org-table-move-column-right}. + +@node Document Structure +@chapter Document Structure + +@cindex document structure +@cindex structure of document +Org is an outliner. Outlines allow a document to be organized in +a hierarchical structure, which, least for me, is the best +representation of notes and thoughts. An overview of this structure +is achieved by folding, i.e., hiding large parts of the document to +show only the general document structure and the parts currently being +worked on.

To minimize confusion with normal +text, those are limited to one character only.

If you have activated alphabetical lists, you +can also use counters like @samp{[@@b]}.}. Those +constructs can be used in any item of the list in order to enforce +a particular numbering. + +@item +@emph{Description} list items are unordered list items, and contain the +separator @samp{::} to distinguish the description @emph{term} from the +description. +@end itemize + +Items belonging to the same list must have the same indentation on the +first line. In particular, if an ordered list reaches number @samp{10.}, +then the 2-digit numbers must be written left-aligned with the other +numbers in the list. An item ends before the next line that is less +or equally indented than its bullet/number. + +A list ends whenever every item has ended, which means before any line +less or equally indented than items at top level. It also ends before +two blank lines. In that case, all items are closed. Here is an +example: + +@example +* Lord of the Rings +My favorite scenes are (in this order) +1.

You can +customize this behavior using the variable +@code{org-table-use-standard-references}.} + +@example +@@ROW$COLUMN +@end example + + +Column specifications can be absolute like @samp{$1}, @samp{$2}, @dots{}, @samp{$N}, or +relative to the current column, i.e., the column of the field which is +being computed, like @samp{$+1} or @samp{$-2}. @samp{$<} and @samp{$>} are immutable +references to the first and last column, respectively, and you can use +@samp{$>>>} to indicate the third column from the right. + +The row specification only counts data lines and ignores horizontal +separator lines, or ``hlines''. Like with columns, you can use absolute +row numbers @samp{@@1}, @samp{@@2}, @dots{}, @samp{@@N}, and row numbers relative to the +current row like @samp{@@+3} or @samp{@@-1}. @samp{@@<} and @samp{@@>} are immutable +references the first and last row in the table, respectively. You may +also specify the row relative to one of the hlines: @samp{@@I} refers to the +first hline, @samp{@@II} to the second, etc. @samp{@@-I} refers to the first such +line above the current line, @samp{@@+I} to the first such line below the +current line. You can also write @samp{@@III+2} which is the second data +line after the third hline in the table. + +@samp{@@0} and @samp{$0} refer to the current row and column, respectively, i.e., +to the row/column for the field being computed. Also, if you omit +either the column or the row part of the reference, the current +row/column is implied. + +Org's references with @emph{unsigned} numbers are fixed references in the +sense that if you use the same reference in the formula for two +different fields, the same field is referenced each time.

For +example: + +@example +'(substring "$1" $2 $3);L +@end example + + +@noindent +extracts the part of the string in column 1 between the character +positions specified in the integers in column 2 and 3 and it is easier +to read than the equivalent: + +@example +'(substring $1 (string-to-number $2) (string-to-number $3)) +@end example + +@node Durations and time values +@subsection Durations and time values + +@cindex duration, computing +@cindex time, computing +@vindex org-table-duration-custom-format + +If you want to compute time values use the @samp{T}, @samp{t}, or @samp{U} flag, +either in Calc formulas or Elisp formulas: + +@example +| Task 1 | Task 2 | Total | +|---------+----------+----------| +| 2:12 | 1:47 | 03:59:00 | +| 2:12 | 1:47 | 03:59 | +| 3:02:20 | -2:07:00 | 0.92 | +#+TBLFM: @@2$3=$1+$2;T::@@3$3=$1+$2;U::@@4$3=$1+$2;t +@end example + +Input duration values must be of the form @samp{HH:MM[:SS]}, where seconds +are optional. With the @samp{T} flag, computed durations are displayed as +@samp{HH:MM:SS} (see the first formula above). With the @samp{U} flag, seconds +are omitted so that the result is only @samp{HH:MM} (see second formula +above). Zero-padding of the hours field depends upon the value of the +variable @code{org-table-duration-hour-zero-padding}. + +With the @samp{t} flag, computed durations are displayed according to the +value of the option @code{org-table-duration-custom-format}, which defaults +to @code{hours} and displays the result as a fraction of hours (see the +third formula in the example above). + +Negative duration values can be manipulated as well, and integers are +considered as seconds in addition and subtraction. + +@node Field and range formulas +@subsection Field and range formulas + +@cindex field formula +@cindex range formula +@cindex formula, for individual table field +@cindex formula, for range of fields + +To assign a formula to a particular field, type it directly into the +field, preceded by @samp{:=}, for example @samp{vsum(@@II..III)}. When you press +@kbd{@key{TAB}} or @kbd{@key{RET}} or @kbd{C-c C-c} with point +still in the field, the formula is stored as the formula for this +field, evaluated, and the current field is replaced with the result. + +@cindex @samp{TBLFM}, keyword +Formulas are stored in a special @samp{TBLFM} keyword located directly +below the table. If you type the equation in the fourth field of the +third data line in the table, the formula looks like @samp{@@3$4=$1+$2}. +When inserting/deleting/swapping column and rows with the appropriate +commands, @emph{absolute references} (but not relative ones) in stored +formulas are modified in order to still reference the same field. To +avoid this from happening, in particular in range references, anchor +ranges at the table borders (using @samp{@@<}, @samp{@@>}, @samp{$<}, @samp{$>}), or at +hlines using the @samp{@@I} notation. Automatic adaptation of field +references does not happen if you edit the table structure with normal +editing commands---you must fix the formulas yourself. + +Instead of typing an equation into the field, you may also use the +following command + +@table @asis +@item @kbd{C-u C-c =} (@code{org-table-eval-formula}) +@kindex C-u C-c = +@findex org-table-eval-formula +Install a new formula for the current field. The command prompts +for a formula with default taken from the @samp{TBLFM} keyword, +applies it to the current field, and stores it. +@end table + +The left-hand side of a formula can also be a special expression in +order to assign the formula to a number of different fields. There is +no keyboard shortcut to enter such range formulas. To add them, use +the formula editor (see @ref{Editing and debugging formulas}) or edit +the @samp{TBLFM} keyword directly. + +@table @asis +@item @samp{$2=} +Column formula, valid for the entire column.

Therefore a header is mandatory when you +use column formulas and want to add hlines to group rows, like for +example to separate a total row at the bottom from the summand rows +above. (ii) Fields that already get a value from a field/range +formula are left alone by column formulas. These conditions make +column formulas very easy to use. + +To assign a formula to a column, type it directly into any field in +the column, preceded by an equal sign, like @samp{=$1+$2}. When you press +@kbd{@key{TAB}} or @kbd{@key{RET}} or @kbd{C-c C-c} with point +still in the field, the formula is stored as the formula for the +current column, evaluated and the current field replaced with the +result. If the field contains only @samp{=}, the previously stored formula +for this column is used. For each column, Org only remembers the most +recently used formula. In the @samp{TBLFM} keyword, column formulas look +like @samp{$4=$1+$2}. The left-hand side of a column formula can not be +the name of column, it must be the numeric column reference or @samp{$>}. + +Instead of typing an equation into the field, you may also use the +following command: + +@table @asis +@item @kbd{C-c =} (@code{org-table-eval-formula}) +@kindex C-c = +@findex org-table-eval-formula +Install a new formula for the current column and replace current +field with the result of the formula. The command prompts for +a formula, with default taken from the @samp{TBLFM} keyword, applies it +to the current field and stores it. With a numeric prefix argument, +e.g., @kbd{C-5 C-c =}, the command applies it to that many +consecutive fields in the current column. +@end table + +@node Lookup functions +@subsection Lookup functions + +@cindex lookup functions in tables +@cindex table lookup functions + +Org has three predefined Emacs Lisp functions for lookups in tables. + +@table @asis +@item @samp{(org-lookup-first VAL S-LIST R-LIST &optional PREDICATE)} +@findex org-lookup-first +Searches for the first element @var{S} in list +@var{S-LIST} for which +@lisp +(PREDICATE VAL S) +@end lisp +is non-@code{nil}; returns the value from the corresponding position in +list @var{R-LIST}.

However, powerful +lookups can be built when this function is combined with other Emacs +Lisp functions. +@end table + +If the ranges used in these functions contain empty fields, the @samp{E} +mode for the formula should usually be specified: otherwise empty +fields are not included in @var{S-LIST} and/or @var{R-LIST} +which can, for example, result in an incorrect mapping from an element +of @var{S-LIST} to the corresponding element of +@var{R-LIST}. + +These three functions can be used to implement associative arrays, +count matching cells, rank results, group data, etc. For practical +examples see @uref{https://orgmode.org/worg/org-tutorials/org-lookups.html, this tutorial on Worg}. + +@node Editing and debugging formulas +@subsection Editing and debugging formulas + +@cindex formula editing +@cindex editing, of table formulas + +@vindex org-table-use-standard-references +You can edit individual formulas in the minibuffer or directly in the +field.

You only need to bother about the rules above +when inserting directly, or yanking, a URI within square brackets. +When in doubt, you may use the function @code{org-link-escape}, which turns +a link string into its escaped form. + +Once a link in the buffer is complete, with all brackets present, Org +changes the display so that @samp{DESCRIPTION} is displayed instead of +@samp{[[LINK][DESCRIPTION]]} and @samp{LINK} is displayed instead of @samp{[[LINK]]}. +Links are highlighted in the @code{org-link} face, which, by default, is an +underlined face. + +You can directly edit the visible part of a link. This can be either +the @var{LINK} part, if there is no description, or the +@var{DESCRIPTION} part otherwise. To also edit the invisible +@var{LINK} part, use @kbd{C-c C-l} with point on the link +(see @ref{Handling Links}). + +If you place point at the beginning or just behind the end of the +displayed text and press @kbd{@key{BS}}, you remove +the---invisible---bracket at that location@footnote{More accurately, the precise behavior depends on how point +arrived there---see @ref{Invisible Text,Invisible Text,,elisp,}.}. This makes the link +incomplete and the internals are again displayed as plain text. +Inserting the missing bracket hides the link internals again.

Most notably, a construct like @samp{[[#my-custom-id]]} +specifically targets the entry with the @samp{CUSTOM_ID} property set to +@samp{my-custom-id}. Also, an internal link looking like @samp{[[*Some +section]]} points to a headline with the name @samp{Some section}@footnote{To insert a link targeting a headline, in-buffer completion +can be used.

Org provides a linter to assist +you in the process, if needed. See @ref{Org Syntax}. + +During export, internal links are used to mark objects and assign them +a number. Marked objects are then referenced by links pointing to +them. In particular, links without a description appear as the number +assigned to the marked object@footnote{When targeting a @samp{NAME} keyword, the @samp{CAPTION} keyword is +mandatory in order to get proper numbering (see @ref{Captions}).}. In the following excerpt from +an Org buffer + +@example +1. one item +2. <>another item +Here we refer to item [[target]]. +@end example + +@noindent +The last sentence will appear as @samp{Here we refer to item 2} when +exported. + +In non-Org files, the search looks for the words in the link text.

Because of its importance, we suggest to bind it +to a widely available key (see @ref{Activation}). It stores a link to the +current location. The link is stored for later insertion into an Org +buffer---see below. The kind of link that is created depends on the +current buffer: + +@table @asis +@item @emph{Org mode buffers} +For Org files, if there is a @samp{<>} at point, the link points +to the target. Otherwise it points to the current headline, which +is also the description@footnote{If the headline contains a timestamp, it is removed from the +link, which results in a wrong link---you should avoid putting +a timestamp in the headline.}. + +@vindex org-id-link-to-org-use-id +@cindex @samp{CUSTOM_ID}, property +@cindex @samp{ID}, property +If the headline has a @samp{CUSTOM_ID} property, store a link to this +custom ID@. In addition or alternatively, depending on the value of +@code{org-id-link-to-org-use-id}, create and/or use a globally unique +@samp{ID} property for the link@footnote{The Org Id library must first be loaded, either through +@code{org-customize}, by enabling @code{id} in @code{org-modules}, or by adding +@samp{(require 'org-id)} in your Emacs init file.}. So using this command in Org +buffers potentially creates two links: a human-readable link from +the custom ID, and one that is globally unique and works even if the +entry is moved from file to file. The @samp{ID} property can be either a +UUID (default) or a timestamp, depending on @code{org-id-method}. Later, +when inserting the link, you need to decide which one to use. + +@item @emph{Email/News clients: VM, Rmail, Wanderlust, MH-E, Gnus} +@vindex org-link-email-description-format +Pretty much all Emacs mail clients are supported. The link points +to the current article, or, in some Gnus buffers, to the group. The +description is constructed according to the variable +@code{org-link-email-description-format}. By default, it refers to the +addressee and the subject. + +@item @emph{Web browsers: W3, W3M and EWW} +Here the link is the current URL, with the page title as the +description. + +@item @emph{Contacts: BBDB} +Links created in a BBDB buffer point to the current entry. + +@item @emph{Chat: IRC} +@vindex org-irc-links-to-logs +For IRC links, if the variable @code{org-irc-link-to-logs} is non-@code{nil}, +create a @samp{file} style link to the relevant point in the logs for the +current conversation. Otherwise store an @samp{irc} style link to the +user/channel/server under the point. + +@item @emph{Other files} +For any other file, the link points to the file, with a search +string (see @ref{Search Options}) pointing to the contents +of the current line. If there is an active region, the selected +words form the basis of the search string. You can write custom Lisp +functions to select the search string and perform the search for +particular file types (see @ref{Custom Searches}). + +You can also define dedicated links to other files. See @ref{Adding Hyperlink Types}. + +@item @emph{Agenda view} +When point is in an agenda view, the created link points to the +entry referenced by the current line. +@end table + +From an Org buffer, the following commands create, navigate or, more +generally, act on links. + +@table @asis +@item @kbd{C-c C-l} (@code{org-insert-link}) +@kindex C-c C-l +@findex org-insert-link +@cindex link completion +@cindex completion, of links +@cindex inserting links +@vindex org-link-keep-stored-after-insertion +Insert a link@footnote{Note that you do not have to use this command to insert +a link.

You can just type a link, using text for an internal +link, or one of the link type prefixes mentioned in the examples +above. The link is inserted into the buffer, along with +a descriptive text@footnote{After insertion of a stored link, the link will be removed +from the list of stored links.

You may also use a numeric prefix argument to quickly +select a specific state. For example @kbd{C-3 C-c C-t} changes +the state immediately to @samp{VERIFY}. Or you can use @kbd{S-@key{RIGHT}} +and @kbd{S-@key{LEFT}} to go forward and backward through the states. +If you define many keywords, you can use in-buffer completion (see +@ref{Completion}) or a special one-key selection scheme (see @ref{Fast access to TODO states}) to insert these words into the buffer. +Changing a TODO state can be logged with a timestamp, see @ref{Tracking TODO state changes}, for more information. + +@node TODO types +@subsection TODO keywords as types + +@cindex TODO types +@cindex names as TODO keywords +@cindex types as TODO keywords + +The second possibility is to use TODO keywords to indicate different +@emph{types} of action items. For example, you might want to indicate that +items are for ``work'' or ``home''. Or, when you work with several people +on a single project, you might want to assign action items directly to +persons, by using their names as TODO keywords. This type of +functionality is actually much better served by using tags (see +@ref{Tags}), so the TODO implementation is kept just for backward +compatibility. + +Using TODO types, it would be set up like this: + +@lisp +(setq org-todo-keywords '((type "Fred" "Sara" "Lucy" "|" "DONE"))) +@end lisp + +In this case, different keywords do not indicate states, but +rather different types. So the normal work flow would be to assign +a task to a person, and later to mark it DONE@. Org mode supports this +style by adapting the workings of the command @kbd{C-c C-t}@footnote{This is also true for the @kbd{t} command in the agenda +buffer.}. When used several times in succession, it still +cycles through all names, in order to first select the right type for +a task. But when you return to the item after some time and execute +@kbd{C-c C-t} again, it will switch from any name directly to +@samp{DONE}. Use prefix arguments or completion to quickly select +a specific name. You can also review the items of a specific TODO +type in a sparse tree by using a numeric prefix to @kbd{C-c / t}. +For example, to see all things Lucy has to do, you would use +@kbd{C-3 C-c / t}. To collect Lucy's items from all agenda files +into a single buffer, you would use the numeric prefix argument as +well when creating the global TODO list: @kbd{C-3 M-x org-agenda t}. + +@node Multiple sets in one file +@subsection Multiple keyword sets in one file + +@cindex TODO keyword sets + +Sometimes you may want to use different sets of TODO keywords in +parallel. For example, you may want to have the basic TODO/DONE, but +also a workflow for bug fixing, and a separate state indicating that +an item has been canceled---so it is not DONE, but also does not +require action. Your setup would then look like this: + +@lisp +(setq org-todo-keywords + '((sequence "TODO" "|" "DONE") + (sequence "REPORT" "BUG" "KNOWNCAUSE" "|" "FIXED") + (sequence "|" "CANCELED"))) +@end lisp + +The keywords should all be different, this helps Org mode keep track +of which subsequence should be used for a given entry. In this setup, +@kbd{C-c C-t} only operates within a sub-sequence, so it switches +from @samp{DONE} to (nothing) to @samp{TODO}, and from @samp{FIXED} to (nothing) to +@samp{REPORT}. Therefore you need a mechanism to initially select the +correct sequence. In addition to typing a keyword or using completion +(see @ref{Completion}), you may also apply the following commands: + +@table @asis +@item @kbd{C-u C-u C-c C-t} +@itemx @kbd{C-S-@key{RIGHT}} +@itemx @kbd{C-S-@key{LEFT}} +@kindex C-S-RIGHT +@kindex C-S-LEFT +@kindex C-u C-u C-c C-t +These keys jump from one TODO sub-sequence to the next. In the +above example, @kbd{C-u C-u C-c C-t} or @kbd{C-S-@key{RIGHT}} +would jump from @samp{TODO} or @samp{DONE} to @samp{REPORT}, and any of the words +in the second row to @samp{CANCELED}. Note that the @kbd{C-S-} key +binding conflict with shift-selection (see @ref{Conflicts}). + +@item @kbd{S-@key{RIGHT}} +@itemx @kbd{S-@key{LEFT}} +@kindex S-RIGHT +@kindex S-LEFT +@kbd{S-@key{LEFT}} and @kbd{S-@key{RIGHT}} walk through @emph{all} keywords +from all sub-sequences, so for example @kbd{S-@key{RIGHT}} would +switch from @samp{DONE} to @samp{REPORT} in the example above. For +a discussion of the interaction with shift-selection, see @ref{Conflicts}. +@end table + +@node Fast access to TODO states +@subsection Fast access to TODO states + +If you would like to quickly change an entry to an arbitrary TODO +state instead of cycling through the states, you can set up keys for +single-letter access to the states.

If it is not enabled it is not an error, +but the consistency graphs are largely meaningless. +@end enumerate + +To give you an idea of what the above rules look like in action, here's an +actual habit with some history: + +@example +** TODO Shave + SCHEDULED: <2009-10-17 Sat .+2d/4d> + :PROPERTIES: + :STYLE: habit + :LAST_REPEAT: [2009-10-19 Mon 00:36] + :END: + - State "DONE" from "TODO" [2009-10-15 Thu] + - State "DONE" from "TODO" [2009-10-12 Mon] + - State "DONE" from "TODO" [2009-10-10 Sat] + - State "DONE" from "TODO" [2009-10-04 Sun] + - State "DONE" from "TODO" [2009-10-02 Fri] + - State "DONE" from "TODO" [2009-09-29 Tue] + - State "DONE" from "TODO" [2009-09-25 Fri] + - State "DONE" from "TODO" [2009-09-19 Sat] + - State "DONE" from "TODO" [2009-09-16 Wed] + - State "DONE" from "TODO" [2009-09-12 Sat] +@end example + +What this habit says is: I want to shave at most every 2 days---given +by the @samp{SCHEDULED} date and repeat interval---and at least every +4 days. If today is the 15th, then the habit first appears in the +agenda (see @ref{Agenda Views}) on Oct 17, after the minimum of 2 days has +elapsed, and will appear overdue on Oct 19, after four days have +elapsed. + +What's really useful about habits is that they are displayed along +with a consistency graph, to show how consistent you've been at +getting that task done in the past. This graph shows every day that +the task was done over the past three weeks, with colors for each day. +The colors used are: + +@table @asis +@item Blue +If the task was not to be done yet on that day. +@item Green +If the task could have been done on that day. +@item Yellow +If the task was going to be overdue the next day. +@item Red +If the task was overdue on that day. +@end table + +In addition to coloring each day, the day is also marked with an +asterisk if the task was actually done that day, and an exclamation +mark to show where the current day falls in the graph. + +There are several configuration variables that can be used to change +the way habits are displayed in the agenda. + +@table @asis +@item @code{org-habit-graph-column} +@vindex org-habit-graph-column +The buffer column at which the consistency graph should be drawn. +This overwrites any text in that column, so it is a good idea to +keep your habits' titles brief and to the point. + +@item @code{org-habit-preceding-days} +@vindex org-habit-preceding-days +The amount of history, in days before today, to appear in +consistency graphs. + +@item @code{org-habit-following-days} +@vindex org-habit-following-days +The number of days after today that appear in consistency graphs. + +@item @code{org-habit-show-habits-only-for-today} +@vindex org-habit-show-habits-only-for-today +If non-@code{nil}, only show habits in today's agenda view.

They are also subject to tag filtering, if +you have habits which should only be done in certain contexts, for +example. + +@node Priorities +@section Priorities + +@cindex priorities +@cindex priority cookie + +If you use Org mode extensively, you may end up with enough TODO items +that it starts to make sense to prioritize them. Prioritizing can be +done by placing a @emph{priority cookie} into the headline of a TODO item +right after the TODO keyword, like this: + +@example +*** TODO [#A] Write letter to Sam Fortune +@end example + + +@vindex org-priority-faces +By default, Org mode supports three priorities: @samp{A}, @samp{B}, and @samp{C}. +@samp{A} is the highest priority.

Outside the +agenda, they have no inherent meaning to Org mode. The cookies are +displayed with the face defined by the variable @code{org-priority-faces}, +which can be customized. + +You can also use numeric values for priorities, such as + +@example +*** TODO [#1] Write letter to Sam Fortune +@end example + + +When using numeric priorities, you need to set @code{org-priority-highest}, +@code{org-priority-lowest} and @code{org-priority-default} to integers, which +must all be strictly inferior to 65. + +Priorities can be attached to any outline node; they do not need to be +TODO items. + +@table @asis +@item @kbd{C-c ,} (@code{org-priority}) +@kindex C-c , +@findex org-priority +Set the priority of the current headline.

You can do this by creating an outline tree +below a TODO item, with detailed subtasks on the tree@footnote{To keep subtasks out of the global TODO list, see the option +@code{org-agenda-todo-list-sublevels}.}. To keep +an overview of the fraction of subtasks that have already been marked +as done, insert either @samp{[/]} or @samp{[%]} anywhere in the headline. These +cookies are updated each time the TODO status of a child changes, or +when pressing @kbd{C-c C-c} on the cookie. For example: + +@example +* Organize Party [33%] +** TODO Call people [1/2] +*** TODO Peter +*** DONE Sarah +** TODO Buy food +** DONE Talk to neighbor +@end example + +@cindex @samp{COOKIE_DATA}, property +If a heading has both checkboxes and TODO children below it, the +meaning of the statistics cookie become ambiguous.

This feature is +similar to TODO items (see @ref{TODO Items}), but is more lightweight. +Checkboxes are not included into the global TODO list, so they are +often great to split a task into a number of simple steps. Or you can +use them in a shopping list. + +Here is an example of a checkbox list. + +@example +* TODO Organize party [2/4] + - [-] call people [1/3] + - [ ] Peter + - [X] Sarah + - [ ] Sam + - [X] order food + - [ ] think about what music to play + - [X] talk to the neighbors +@end example + +Checkboxes work hierarchically, so if a checkbox item has children +that are checkboxes, toggling one of the children checkboxes makes the +parent checkbox reflect if none, some, or all of the children are +checked. + +@cindex statistics, for checkboxes +@cindex checkbox statistics +@cindex @samp{COOKIE_DATA}, property +@vindex org-hierarchical-checkbox-statistics +The @samp{[2/4]} and @samp{[1/3]} in the first and second line are cookies +indicating how many checkboxes present in this entry have been checked +off, and the total number of checkboxes present. This can give you an +idea on how many checkboxes remain, even without opening a folded +entry. The cookies can be placed into a headline or into (the first +line of) a plain list item. Each cookie covers checkboxes of direct +children structurally below the headline/item on which the cookie +appears@footnote{Set the variable @code{org-hierarchical-checkbox-statistics} if you +want such cookies to count all checkboxes below the cookie, not just +those belonging to direct children.}. You have to insert the cookie yourself by typing +either @samp{[/]} or @samp{[%]}. With @samp{[/]} you get an @samp{n out of m} result, as +in the examples above. With @samp{[%]} you get information about the +percentage of checkboxes checked (in the above example, this would be +@samp{[50%]} and @samp{[33%]}, respectively). In a headline, a cookie can count +either checkboxes below the heading or TODO states of children, and it +displays whatever was changed last.

For a complete description +with many examples, see @ref{Matching tags and properties}. + +@node Properties and Columns +@chapter Properties and Columns + +@cindex properties + +A property is a key-value pair associated with an entry. Properties +can be set so they are associated with a single entry, with every +entry in a tree, or with the whole buffer. + +There are two main applications for properties in Org mode. First, +properties are like tags, but with a value. Imagine maintaining +a file where you document bugs and plan releases for a piece of +software. Instead of using tags like @samp{release_1}, @samp{release_2}, you +can use a property, say @samp{Release}, that in different subtrees has +different values, such as @samp{1.0} or @samp{2.0}. Second, you can use +properties to implement (very basic) database capabilities in an Org +buffer. Imagine keeping track of your music CDs, where properties +could be things such as the album, artist, date of release, number of +tracks, and so on. + +Properties can be conveniently edited and viewed in column view (see +@ref{Column View}). + +@menu +* Property Syntax:: How properties are spelled out. +* Special Properties:: Access to other Org mode features. +* Property Searches:: Matching property values. +* Property Inheritance:: Passing values down a tree. +* Column View:: Tabular viewing and editing. +@end menu + +@node Property Syntax +@section Property Syntax + +@cindex property syntax +@cindex drawer, for properties + +Properties are key--value pairs. When they are associated with +a single entry or with a tree they need to be inserted into a special +drawer (see @ref{Drawers}) with the name @samp{PROPERTIES}, which has to be +located right below a headline, and its planning line (see @ref{Deadlines and Scheduling}) when applicable. Each property is specified on +a single line, with the key---surrounded by colons---first, and the +value after it. Keys are case-insensitive. Here is an example: + +@example +* CD collection +** Classic +*** Goldberg Variations + :PROPERTIES: + :Title: Goldberg Variations + :Composer: J.S. Bach + :Artist: Glenn Gould + :Publisher: Deutsche Grammophon + :NDisks: 1 + :END: +@end example + +Depending on the value of @code{org-use-property-inheritance}, a property +set this way is associated either with a single entry, or with the +sub-tree defined by the entry, see @ref{Property Inheritance}. + +You may define the allowed values for a particular property @samp{Xyz} by +setting a property @samp{Xyz_ALL}. This special property is @emph{inherited}, +so if you set it in a level 1 entry, it applies to the entire tree. +When allowed values are defined, setting the corresponding property +becomes easier and is less prone to typing errors. For the example +with the CD collection, we can pre-define publishers and the number of +disks in a box like this: + +@example +* CD collection + :PROPERTIES: + :NDisks_ALL: 1 2 3 4 + :Publisher_ALL: "Deutsche Grammophon" Philips EMI + :END: +@end example + +Properties can be inserted on buffer level. That means they apply +before the first headline and can be inherited by all entries in a +file. Property blocks defined before first headline needs to be +located at the top of the buffer, allowing only comments above. + +Properties can also be defined using lines like: + +@cindex @samp{_ALL} suffix, in properties +@cindex @samp{PROPERTY}, keyword +@example +#+PROPERTY: NDisks_ALL 1 2 3 4 +@end example + + +@cindex @samp{+} suffix, in properties +If you want to add to the value of an existing property, append a @samp{+} +to the property name. The following results in the property @samp{var} +having the value @samp{foo=1 bar=2}. + +@example +#+PROPERTY: var foo=1 +#+PROPERTY: var+ bar=2 +@end example + +It is also possible to add to the values of inherited properties. The +following results in the @samp{Genres} property having the value @samp{Classic +Baroque} under the @samp{Goldberg Variations} subtree. + +@example +* CD collection +** Classic + :PROPERTIES: + :Genres: Classic + :END: +*** Goldberg Variations + :PROPERTIES: + :Title: Goldberg Variations + :Composer: J.S.

However, if you find +inheritance useful, you can turn it on by setting the variable +@code{org-use-property-inheritance}. It may be set to @code{t} to make all +properties inherited from the parent, to a list of properties that +should be inherited, or to a regular expression that matches inherited +properties. If a property has the value @code{nil}, this is interpreted as +an explicit un-define of the property, so that inheritance search +stops at this value and returns @code{nil}. + +Org mode has a few properties for which inheritance is hard-coded, at +least for the special applications for which they are used: + +@table @asis +@item @code{COLUMNS} +@cindex @samp{COLUMNS}, property +The @samp{COLUMNS} property defines the format of column view (see +@ref{Column View}).

In column view, each outline node is turned into a table row. +Columns in this table provide access to properties of the entries. +Org mode implements columns by overlaying a tabular structure over the +headline of each item. While the headlines have been turned into +a table row, you can still change the visibility of the outline tree. +For example, you get a compact table by switching to ``contents'' +view---@kbd{S-@key{TAB}} @kbd{S-@key{TAB}}, or simply @kbd{c} +while column view is active---but you can still open, read, and edit +the entry below each headline. Or, you can switch to column view +after executing a sparse tree command and in this way get a table only +for the selected items.

The general +definition looks like this: + +@example +%[WIDTH]PROPERTY[(TITLE)][@{SUMMARY-TYPE@}] +@end example + + +@noindent +Except for the percent sign and the property name, all items are +optional.

For example, +instead of estimating a particular task will take 5 days, you might +estimate it as 5--6 days if you're fairly confident you know how much +work is required, or 1--10 days if you do not really know what needs +to be done. Both ranges average at 5.5 days, but the first represents +a more predictable delivery. + +When combining a set of such estimates, simply adding the lows and +highs produces an unrealistically wide result. Instead, @samp{est+} adds +the statistical mean and variance of the subtasks, generating a final +estimate from the sum. For example, suppose you had ten tasks, each +of which was estimated at 0.5 to 2 days of work. Straight addition +produces an estimate of 5 to 20 days, representing what to expect if +everything goes either extremely well or extremely poorly. In +contrast, @samp{est+} estimates the full job more realistically, at 10--15 +days. + +Here is an example for a complete columns definition, along with +allowed values@footnote{Please note that the @samp{COLUMNS} definition must be on a single +line; it is wrapped here only because of formatting constraints.}. + +@example +:COLUMNS: %25ITEM %9Approved(Approved?)@{X@} %Owner %11Status \ + %10Time_Estimate@{:@} %CLOCKSUM %CLOCKSUM_T +:Owner_ALL: Tammy Mark Karl Lisa Don +:Status_ALL: "In progress" "Not started yet" "Finished" "" +:Approved_ALL: "[ ]" "[X]" +@end example + +@noindent +The first column, @samp{%25ITEM}, means the first 25 characters of the item +itself, i.e., of the headline.

When no width is given after the @samp{%} character, the +column is exactly as wide as it needs to be in order to fully display +all values. The @samp{Approved} column does have a modified title +(@samp{Approved?}, with a question mark). Summaries are created for the +@samp{Time_Estimate} column by adding time duration expressions like HH:MM, +and for the @samp{Approved} column, by providing an @samp{[X]} status if all +children have been checked.

In the following example: + +@example +** TODO Pay the rent + DEADLINE: <2005-10-01 Sat +1m> +@end example + +@noindent +the @samp{+1m} is a repeater; the intended interpretation is that the task +has a deadline on @samp{<2005-10-01>} and repeats itself every (one) month +starting from that time. You can use yearly, monthly, weekly, daily +and hourly repeat cookies by using the @samp{y}, @samp{m}, @samp{w}, @samp{d} and @samp{h} +letters. If you need both a repeater and a special warning period in +a deadline entry, the repeater should come first and the warning +period last + +@example +DEADLINE: <2005-10-01 Sat +1m -3d> +@end example + + +@vindex org-todo-repeat-to-state +Deadlines and scheduled items produce entries in the agenda when they +are over-due, so it is important to be able to mark such an entry as +done once you have done so. When you mark a @samp{DEADLINE} or +a @samp{SCHEDULED} with the TODO keyword @samp{DONE}, it no longer produces +entries in the agenda. The problem with this is, however, is that +then also the @emph{next} instance of the repeated entry will not be +active. Org mode deals with this in the following way: when you try +to mark such an entry as done, using @kbd{C-c C-t}, it shifts the +base date of the repeating timestamp by the repeater interval, and +immediately sets the entry state back to TODO@footnote{In fact, the target state is taken from, in this sequence, the +@samp{REPEAT_TO_STATE} property, the variable @code{org-todo-repeat-to-state} if +it is a string, the previous TODO state if @code{org-todo-repeat-to-state} +is @code{t}, or the first state of the TODO state sequence.}. In the example +above, setting the state to @samp{DONE} would actually switch the date like +this: + +@example +** TODO Pay the rent + DEADLINE: <2005-11-01 Tue +1m> +@end example + +To mark a task with a repeater as DONE, use @kbd{C-- 1 C-c C-t}, +i.e., @code{org-todo} with a numeric prefix argument of @samp{-1}. + +@vindex org-log-repeat +A timestamp@footnote{You can change this using the option @code{org-log-repeat}, or the +@samp{STARTUP} options @samp{logrepeat}, @samp{lognoterepeat}, and @samp{nologrepeat}. +With @samp{lognoterepeat}, you will also be prompted for a note.} is added under the deadline, to keep a record that +you actually acted on the previous instance of this deadline. + +As a consequence of shifting the base date, this entry is no longer +visible in the agenda when checking past dates, but all future +instances will be visible. + +With the @samp{+1m} cookie, the date shift is always exactly one month. So +if you have not paid the rent for three months, marking this entry +DONE still keeps it as an overdue deadline. Depending on the task, +this may not be the best way to handle it. For example, if you forgot +to call your father for 3 weeks, it does not make sense to call him +3 times in a single day to make up for it. Finally, there are tasks, +like changing batteries, which should always repeat a certain time +@emph{after} the last time you did it. For these tasks, Org mode has +special repeaters @samp{++} and @samp{.+}. For example: + +@example +** TODO Call Father + DEADLINE: <2008-02-10 Sun ++1w> + Marking this DONE shifts the date by at least one week, but also + by as many weeks as it takes to get this date into the future. + However, it stays on a Sunday, even if you called and marked it + done on Saturday. + +** TODO Empty kitchen trash + DEADLINE: <2008-02-08 Fri 20:00 ++1d> + Marking this DONE shifts the date by at least one day, and also + by as many days as it takes to get the timestamp into the future. + Since there is a time in the timestamp, the next deadline in the + future will be on today's date if you complete the task before + 20:00. + +** TODO Check the batteries in the smoke detectors + DEADLINE: <2005-11-01 Tue .+1m> + Marking this DONE shifts the date to one month after today. + +** TODO Wash my hands + DEADLINE: <2019-04-05 08:00 Sun .+1h> + Marking this DONE shifts the date to exactly one hour from now. +@end example + +@vindex org-agenda-skip-scheduled-if-deadline-is-shown +You may have both scheduling and deadline information for a specific +task. If the repeater is set for the scheduling information only, you +probably want the repeater to be ignored after the deadline. If so, +set the variable @code{org-agenda-skip-scheduled-if-deadline-is-shown} to +@code{repeated-after-deadline}. However, any scheduling information +without a repeater is no longer relevant once the task is done, and +thus, removed upon repeating the task. If you want both scheduling +and deadline information to repeat after the same interval, set the +same repeater for both timestamps. + +An alternative to using a repeater is to create a number of copies of +a task subtree, with dates shifted in each copy. The command +@kbd{C-c C-x c} was created for this purpose; it is described in +@ref{Structure Editing}. + +@node Clocking Work Time +@section Clocking Work Time + +@cindex clocking time +@cindex time clocking + +Org mode allows you to clock the time you spend on specific tasks in +a project. When you start working on an item, you can start the +clock. When you stop working on that task, or when you mark the task +done, the clock is stopped and the corresponding time interval is +recorded.

For a specific buffer you can use: + +@example +#+PROPERTY: Effort_ALL 0 0:10 0:30 1:00 2:00 3:00 4:00 5:00 6:00 7:00 +#+COLUMNS: %40ITEM(Task) %17Effort(Estimated Effort)@{:@} %CLOCKSUM +@end example + +@noindent +@vindex org-global-properties +@vindex org-columns-default-format +or, even better, you can set up these values globally by customizing +the variables @code{org-global-properties} and +@code{org-columns-default-format}. In particular if you want to use this +setup also in the agenda, a global setup may be advised. + +The way to assign estimates to individual items is then to switch to +column mode, and to use @kbd{S-@key{RIGHT}} and @kbd{S-@key{LEFT}} to +change the value. The values you enter are immediately summed up in +the hierarchy. In the column next to it, any clocked time is +displayed. + +@vindex org-agenda-columns-add-appointments-to-effort-sum +If you switch to column view in the daily/weekly agenda, the effort +column summarizes the estimated work effort for each day@footnote{Please note the pitfalls of summing hierarchical data in +a flat list (see @ref{Agenda Column View}).}, and +you can use this to find space in your schedule. To get an overview +of the entire part of the day that is committed, you can set the +option @code{org-agenda-columns-add-appointments-to-effort-sum}. The +appointments on a day that take place over a specified time interval +are then also added to the load estimate of the day. + +Effort estimates can be used in secondary agenda filtering that is +triggered with the @kbd{/} key in the agenda (see @ref{Agenda Commands}).

Parentheses are currently not +implemented. Each element in the search is either a tag, a regular +expression matching tags, or an expression like @samp{PROPERTY OPERATOR +VALUE} with a comparison operator, accessing a property value. Each +element may be preceded by @samp{-} to select against it, and @samp{+} is +syntactic sugar for positive selection. The AND operator @samp{&} is +optional when @samp{+} or @samp{-} is present. Here are some examples, using +only tags. + +@table @asis +@item @samp{+work-boss} +Select headlines tagged @samp{work}, but discard those also tagged +@samp{boss}. + +@item @samp{work|laptop} +Selects lines tagged @samp{work} or @samp{laptop}. + +@item @samp{work|laptop+night} +Like before, but require the @samp{laptop} lines to be tagged also +@samp{night}. +@end table + +@cindex regular expressions, with tags search +Instead of a tag, you may also specify a regular expression enclosed +in curly braces (see @ref{Regular Expressions}). For example, +@samp{work+@{^boss.*@}} matches headlines that contain the tag @samp{:work:} and +any tag @emph{starting} with @samp{boss}. + +@cindex group tags, as regular expressions +Group tags (see @ref{Tag Hierarchy}) are expanded as regular expressions. +E.g., if @samp{work} is a group tag for the group @samp{:work:lab:conf:}, then +searching for @samp{work} also searches for @samp{@{\(?:work\|lab\|conf\)@}} and +searching for @samp{-work} searches for all headlines but those with one of +the tags in the group (i.e., @samp{-@{\(?:work\|lab\|conf\)@}}). + +@cindex TODO keyword matching, with tags search +@cindex level, for tags/property match +@cindex category, for tags/property match +@vindex org-odd-levels-only +You may also test for properties (see @ref{Properties and Columns}) at the +same time as matching tags. The properties may be real properties, or +special properties that represent other metadata (see @ref{Special Properties}). For example, the property @samp{TODO} represents the TODO +keyword of the entry. Or, the property @samp{LEVEL} represents the level +of an entry. So searching @samp{+LEVEL=3+boss-TODO​="DONE"} lists all level +three headlines that have the tag @samp{boss} and are @emph{not} marked with the +TODO keyword @samp{DONE}. In buffers with @code{org-odd-levels-only} set, +@samp{LEVEL} does not count the number of stars, but @samp{LEVEL=2} corresponds +to 3 stars etc. + +Here are more examples: + +@table @asis +@item @samp{work+TODO​="WAITING"} +Select @samp{work}-tagged TODO lines with the specific TODO keyword +@samp{WAITING}. + +@item @samp{work+TODO​="WAITING"|home+TODO​="WAITING"} +Waiting tasks both at work and at home. +@end table + +When matching properties, a number of different operators can be used +to test the value of a property. Here is a complex example: + +@example ++work-boss+PRIORITY="A"+Coffee="unlimited"+Effort<2 + +With=@{Sarah\|Denny@}+SCHEDULED>="<2008-10-11>" +@end example + +@noindent +The type of comparison depends on how the comparison value is written: + +@itemize +@item +If the comparison value is a plain number, a numerical comparison is +done, and the allowed operators are @samp{<}, @samp{=}, @samp{>}, @samp{<=}, @samp{>=}, and +@samp{<>}. + +@item +If the comparison value is enclosed in double-quotes, a string +comparison is done, and the same operators are allowed. + +@item +If the comparison value is enclosed in double-quotes @emph{and} angular +brackets (like @samp{DEADLINE<​="<2008-12-24 18:30>"}), both values are +assumed to be date/time specifications in the standard Org way, and +the comparison is done accordingly. Valid values also include +@samp{""} for now (including time), @samp{""}, and @samp{""} +for these days at 0:00 hours, i.e., without a time specification. +You can also use strings like @samp{"<+5d>"} or @samp{"<-2m>"} with units @samp{d}, +@samp{w}, @samp{m}, and @samp{y} for day, week, month, and year, respectively. + +@item +If the comparison value is enclosed in curly braces, a regexp match +is performed, with @samp{=} meaning that the regexp matches the property +value, and @samp{<>} meaning that it does not match. +@end itemize + +So the search string in the example finds entries tagged @samp{work} but +not @samp{boss}, which also have a priority value @samp{A}, a @samp{Coffee} property +with the value @samp{unlimited}, an @samp{EFFORT} property that is numerically +smaller than 2, a @samp{With} property that is matched by the regular +expression @samp{Sarah\|Denny}, and that are scheduled on or after October +11, 2008. + +You can configure Org mode to use property inheritance during +a search, but beware that this can slow down searches considerably. +See @ref{Property Inheritance}, for details. + +For backward compatibility, and also for typing speed, there is also +a different way to test TODO states in a search. For this, terminate +the tags/property part of the search string (which may include several +terms connected with @samp{|}) with a @samp{/} and then specify a Boolean +expression just for TODO keywords. The syntax is then similar to that +for tags, but should be applied with care: for example, a positive +selection on several TODO keywords cannot meaningfully be combined +with boolean AND@. However, @emph{negative selection} combined with AND can +be meaningful. To make sure that only lines are checked that actually +have any TODO keyword (resulting in a speed-up), use @kbd{M-x org-agenda M}, or equivalently start the TODO part after the slash +with @samp{!}. Using @kbd{M-x org-agenda M} or @samp{/!} does not match +TODO keywords in a DONE state. Examples: + +@table @asis +@item @samp{work/WAITING} +Same as @samp{work+TODO​="WAITING"}. + +@item @samp{work/!-WAITING-NEXT} +Select @samp{work}-tagged TODO lines that are neither @samp{WAITING} nor +@samp{NEXT}. + +@item @samp{work/!+WAITING|+NEXT} +Select @samp{work}-tagged TODO lines that are either @samp{WAITING} or @samp{NEXT}. +@end table + +@node Search view +@subsection Search view + +@cindex search view +@cindex text search +@cindex searching, for text + +This agenda view is a general text search facility for Org mode +entries.

A double prefix +adds the new filter condition to the one(s) already in place, so +filter elements are accumulated. + +@table @asis +@item @kbd{\} (@code{org-agenda-filter-by-tag}) +@findex org-agenda-filter-by-tag +Filter the agenda view with respect to a tag. You are prompted for +a tag selection letter; @kbd{@key{SPC}} means any tag at all. +Pressing @kbd{@key{TAB}} at that prompt offers completion to select a +tag, including any tags that do not have a selection character. The +command then hides all entries that do not contain or inherit this +tag. Pressing @kbd{+} or @kbd{-} at the prompt switches +between filtering for and against the next tag. To clear the +filter, press @kbd{\} twice (once to call the command again, +and once at the prompt). + +@item @kbd{<} (@code{org-agenda-filter-by-category}) +@findex org-agenda-filter-by-category +Filter by category of the line at point, and show only entries with +this category. When called with a prefix argument, hide all entries +with the category at point. To clear the filter, call this command +again by pressing @kbd{<}. + +@item @kbd{=} (@code{org-agenda-filter-by-regexp}) +@findex org-agenda-filter-by-regexp +Filter the agenda view by a regular expression: only show agenda +entries matching the regular expression the user entered. To clear +the filter, call the command again by pressing @kbd{=}. + +@item @kbd{_} (@code{org-agenda-filter-by-effort}) +@findex org-agenda-filter-by-effort +Filter the agenda view with respect to effort estimates, so select +tasks that take the right amount of time. You first need to set up +a list of efforts globally, for example + +@lisp +(setq org-global-properties + '(("Effort_ALL". "0 0:10 0:30 1:00 2:00 3:00 4:00"))) +@end lisp + +@vindex org-sort-agenda-noeffort-is-high +You can then filter for an effort by first typing an operator, one +of @kbd{<}, @kbd{>} and @kbd{=}, and then the +one-digit index of an effort estimate in your array of allowed +values, where @kbd{0} means the 10th value. The filter then +restricts to entries with effort smaller-or-equal, equal, or +larger-or-equal than the selected value. For application of the +operator, entries without a defined effort are treated according to +the value of @code{org-sort-agenda-noeffort-is-high}. To clear the +filter, press @kbd{_} twice (once to call the command again, +and once at the first prompt). + +@item @kbd{^} (@code{org-agenda-filter-by-top-headline}) +@findex org-agenda-filter-by-top-headline +Filter the current agenda view and only display items that fall +under the same top-level headline as the current entry. To clear +the filter, call this command again by pressing @kbd{^}. + +@item @kbd{/} (@code{org-agenda-filter}) +@findex org-agenda-filter +This is the unified interface to four of the five filter methods +described above. At the prompt, specify different filter elements +in a single string, with full completion support. For example, + +@example ++work-John+<0:10-/plot/ +@end example + + +selects entries with category @samp{work} and effort estimates below 10 +minutes, and deselects entries with tag @samp{John} or matching the +regexp @samp{plot} (see @ref{Regular Expressions}). You can leave @samp{+} out if +that does not lead to ambiguities. The sequence of elements is +arbitrary. The filter syntax assumes that there is no overlap +between categories and tags. Otherwise, tags take priority. If you +reply to the prompt with the empty string, all filtering is removed. +If a filter is specified, it replaces all current filters. But if +you call the command with a double prefix argument, or if you add an +additional @samp{+} (e.g., @samp{++work}) to the front of the string, the new +filter elements are added to the active ones. A single prefix +argument applies the entire filter in a negative sense. + +@item @kbd{|} (@code{org-agenda-filter-remove-all}) +Remove all filters in the current agenda view. +@end table + +@anchor{Computed tag filtering} +@subsubheading Computed tag filtering + +@vindex org-agenda-auto-exclude-function +If the variable @code{org-agenda-auto-exclude-function} is set to +a user-defined function, that function can select tags that should be +used as a tag filter when requested. The function will be called with +lower-case versions of all tags represented in the current view. The +function should return @samp{"-tag"} if the filter should remove +entries with that tag, @samp{"+tag"} if only entries with this tag should +be kept, or @samp{nil} if that tag is irrelevant. For example, let's say +you use a @samp{Net} tag to identify tasks which need network access, an +@samp{Errand} tag for errands in town, and a @samp{Call} tag for making phone +calls. You could auto-exclude these tags based on the availability of +the Internet, and outside of business hours, with something like this: + +@lisp +(defun my-auto-exclude-fn (tag) + (when (cond ((string= tag "net") + (/= 0 (call-process "/sbin/ping" nil nil nil + "-c1" "-q" "-t1" "mail.gnu.org"))) + ((member tag '("errand" "call")) + (let ((hr (nth 2 (decode-time)))) + (or (< hr 8) (> hr 21))))) + (concat "-" tag))) + +(setq org-agenda-auto-exclude-function #'my-auto-exclude-fn) +@end lisp + +You can apply this self-adapting filter by using a triple prefix +argument to @code{org-agenda-filter}, i.e.@tie{}press @kbd{C-u C-u C-u /}, +or by pressing @kbd{@key{RET}} in @code{org-agenda-filter-by-tag}. + +@anchor{Setting limits for the agenda} +@subsubheading Setting limits for the agenda + +@cindex limits, in agenda + +Here is a list of options that you can set, either globally, or +locally in your custom agenda views (see @ref{Custom Agenda Views}). + +@table @asis +@item @code{org-agenda-max-entries} +@vindex org-agenda-max-entries +Limit the number of entries. + +@item @code{org-agenda-max-effort} +@vindex org-agenda-max-effort +Limit the duration of accumulated efforts (as minutes). + +@item @code{org-agenda-max-todos} +@vindex org-agenda-max-todos +Limit the number of entries with TODO keywords. + +@item @code{org-agenda-max-tags} +@vindex org-agenda-max-tags +Limit the number of tagged entries. +@end table + +When set to a positive integer, each option excludes entries from +other categories: for example, @samp{(setq org-agenda-max-effort 100)} +limits the agenda to 100 minutes of effort and exclude any entry that +has no effort property. If you want to include entries with no effort +property, use a negative value for @code{org-agenda-max-effort}. One +useful setup is to use @code{org-agenda-max-entries} locally in a custom +command. For example, this custom command displays the next five +entries with a @samp{NEXT} TODO keyword. + +@lisp +(setq org-agenda-custom-commands + '(("n" todo "NEXT" + ((org-agenda-max-entries 5))))) +@end lisp + +Once you mark one of these five entry as DONE, rebuilding the agenda +will again the next five entries again, including the first entry that +was excluded so far. + +You can also dynamically set temporary limits, which are lost when +rebuilding the agenda: + +@table @asis +@item @kbd{~} (@code{org-agenda-limit-interactively}) +@findex org-agenda-limit-interactively +This prompts for the type of limit to apply and its value. +@end table + +@node Agenda Commands +@section Commands in the Agenda Buffer + +@cindex commands, in agenda buffer + +Entries in the agenda buffer are linked back to the Org file or diary +file where they originate.

The global variables define the behavior for all agenda +commands, including the custom commands.

For example: + +@lisp +(setq org-agenda-custom-commands + '(("w" todo "WAITING" + ((org-agenda-sorting-strategy '(priority-down)) + (org-agenda-prefix-format " Mixed: "))) + ("U" tags-tree "+boss-urgent" + ((org-show-context-detail 'minimal))) + ("N" search "" + ((org-agenda-files '("~org/notes.org")) + (org-agenda-text-search-extra-files nil))))) +@end lisp + +@noindent +Now the @kbd{w} command sorts the collected entries only by +priority, and the prefix format is modified to just say @samp{Mixed:} +instead of giving the category of the entry. The sparse tags tree of +@kbd{U} now turns out ultra-compact, because neither the headline +hierarchy above the match, nor the headline following the match are +shown. The command @kbd{N} does a text search limited to only +a single file. + +For command sets creating a block agenda, @code{org-agenda-custom-commands} +has two separate spots for setting options. You can add options that +should be valid for just a single command in the set, and options that +should be valid for all commands in the set. The former are just +added to the command entry; the latter must come after the list of +command entries. Going back to the block agenda example (see @ref{Block agenda}), let's change the sorting strategy for the @kbd{h} +commands to @code{priority-down}, but let's sort the results for @samp{garden} +tags query in the opposite order, @code{priority-up}. This would look like +this: + +@lisp +(setq org-agenda-custom-commands + '(("h" "Agenda and Home-related tasks" + ((agenda) + (tags-todo "home") + (tags "garden" + ((org-agenda-sorting-strategy '(priority-up))))) + ((org-agenda-sorting-strategy '(priority-down)))) + ("o" "Agenda and Office-related tasks" + ((agenda) + (tags-todo "work") + (tags "office"))))) +@end lisp + +As you see, the values and parentheses setting is a little complex. +When in doubt, use the customize interface to set this variable---it +fully supports its structure. Just one caveat: when setting options +in this interface, the @emph{values} are just Lisp expressions. So if the +value is a string, you need to add the double-quotes around the value +yourself. + +@vindex org-agenda-custom-commands-contexts +To control whether an agenda command should be accessible from +a specific context, you can customize +@code{org-agenda-custom-commands-contexts}. Let's say for example that you +have an agenda command @kbd{o} displaying a view that you only +need when reading emails. Then you would configure this option like +this: + +@lisp +(setq org-agenda-custom-commands-contexts + '(("o" (in-mode . "message-mode")))) +@end lisp + +You can also tell that the command key @kbd{o} should refer to +another command key @kbd{r}. In that case, add this command key +like this: + +@lisp +(setq org-agenda-custom-commands-contexts + '(("o" "r" (in-mode .

You should set this variable only in the +@emph{local settings section} of a custom agenda command (see @ref{Custom Agenda Views}) to make it valid for that specific agenda view. If +no such binding exists, it checks, in sequence, +@code{org-columns-default-format-for-agenda}, the format associated with +the first item in the agenda (through a property or a @samp{#+COLUMNS} +setting in that buffer) and finally @code{org-columns-default-format}. + +@item +@cindex @samp{CLOCKSUM}, special property +If any of the columns has a summary type defined (see @ref{Column attributes}), turning on column view in the agenda visits all +relevant agenda files and make sure that the computations of this +property are up to date. This is also true for the special +@samp{CLOCKSUM} property. Org then sums the values displayed in the +agenda. In the daily/weekly agenda, the sums cover a single day; +in all other views they cover the entire block. + +It is important to realize that the agenda may show the same entry +@emph{twice}---for example as scheduled and as a deadline---and it may +show two entries from the same hierarchy (for example a @emph{parent} +and its @emph{child}). In these cases, the summation in the agenda +leads to incorrect results because some values count double. + +@item +When the column view in the agenda shows the @samp{CLOCKSUM} property, +that is always the entire clocked time for this item.

The back-end uses the deadlines and scheduling dates in Org +TODO items for setting the start and due dates for the iCalendar TODO +entry.

Time zones +should be specified as per the IANA time zone database format, e.g., +@samp{Asia/Almaty}. Alternately, the property value can be @samp{UTC}, to force +UTC time for this entry only. + +The @samp{CLASS} property can be used to specify a per-entry visibility +class or access restrictions, and is applied to any entry with class +information. The iCalendar standard defines three visibility classes: +@table @asis +@item @samp{PUBLIC} +The entry is publicly visible (this is the default). +@item @samp{CONFIDENTIAL} +Only a limited group of clients get access to the +event. +@item @samp{PRIVATE} +The entry can be retrieved only by its owner. +@end table +The server should treat unknown class properties the same as +@samp{PRIVATE}. + +Exporting to iCalendar format depends in large part on the +capabilities of the destination application. Some are more lenient +than others. Consult the Org mode FAQ for advice on specific +applications. + +@node Other Built-in Back-ends +@section Other Built-in Back-ends + +Other export back-ends included with Org are: + +@itemize +@item +@samp{ox-man.el}: Export to a man page. +@end itemize + +To activate such back-ends, either customize @code{org-export-backends} or +load directly with @samp{(require 'ox-man)}.

Here is an example with +two filters; one removes brackets from time stamps, and the other +removes strike-through text. The filter functions are defined in +a code block in the same Org file, which is a handy location for +debugging. + +@example +#+BIND: org-export-filter-timestamp-functions (tmp-f-timestamp) +#+BIND: org-export-filter-strike-through-functions (tmp-f-strike-through) +#+BEGIN_SRC emacs-lisp :exports results :results none + (defun tmp-f-timestamp (s backend info) + (replace-regexp-in-string "&[lg]t;\\|[][]" "" s)) + (defun tmp-f-strike-through (s backend info) "") +#+END_SRC +@end example + +@anchor{Extending an existing back-end} +@subheading Extending an existing back-end + +Some parts of the conversion process can be extended for certain +elements so as to introduce a new or revised translation. That is how +the HTML export back-end was extended to handle Markdown format. The +extensions work seamlessly so any aspect of filtering not done by the +extended back-end is handled by the original back-end. Of all the +export customization in Org, extending is very powerful as it operates +at the parser level. + +For this example, make the @emph{ascii} back-end display the language used +in a source code block. Also make it display only when some attribute +is non-@code{nil}, like the following: + +@example +#+ATTR_ASCII: :language t +@end example + + +Then extend ASCII back-end with a custom ``my-ascii'' back-end. + +@lisp +(defun my-ascii-src-block (src-block contents info) + "Transcode a SRC-BLOCK element from Org to ASCII. +CONTENTS is nil.

If not true, hands over to @emph{ascii} back-end. If +true, which it is in this example, it creates a box around the code +and leaves room for the inserting a string for language. The last +form creates the new back-end that springs to action only when +translating @code{src-block} type elements. + +To use the newly defined back-end, evaluate the following from an Org +buffer: + +@lisp +(org-export-to-buffer 'my-ascii "*Org MY-ASCII Export*") +@end lisp + +Further steps to consider would be an interactive function, +self-installing an item in the export dispatcher menu, and other +user-friendly improvements. + +@node Export in Foreign Buffers +@section Export in Foreign Buffers + +The export back-ends in Org often include commands to convert selected +regions.

Tramp, +while very useful and powerful, tends not to be so efficient for +multiple file transfer and has been known to cause problems under +heavy usage. + +Specialized synchronization utilities offer several advantages. In +addition to timestamp comparison, they also do content and +permissions/attribute checks. For this reason you might prefer to +publish your web to a local directory---possibly even @emph{in place} with +your Org files---and then use Unison or Rsync to do the +synchronization with the remote host. + +Since Unison, for example, can be configured as to which files to +transfer to a certain remote destination, it can greatly simplify the +project publishing definition. Simply keep all files in the correct +location, process your Org files with @code{org-publish} and let the +synchronization tool do the rest. You do not need, in this scenario, +to include attachments such as JPG, CSS or PNG files in the project +definition since the third-party tool syncs them. + +Publishing to a local directory is also much faster than to a remote +one, so that you can afford more easily to republish entire projects. +If you set @code{org-publish-use-timestamps-flag} to @code{nil}, you gain the +main benefit of re-including any changed external files such as source +example files you might include with @samp{INCLUDE} keyword.

Org can manage source code in an Org document +when the source code is identified with begin and end markers. +Working with source code begins with identifying source code blocks. +A source code block can be placed almost anywhere in an Org document; +it is not restricted to the preamble or the end of the document. +However, Org cannot manage a source code block if it is placed inside +an Org comment or within a fixed width section. + +Here is an example source code block in the Emacs Lisp language: + +@example +#+BEGIN_SRC emacs-lisp + (defun org-xor (a b) + "Exclusive or." + (if a (not b) b)) +#+END_SRC +@end example + +Source code blocks are one of many Org block types, which also include +``center'', ``comment'', ``dynamic'', ``example'', ``export'', ``quote'', +``special'', and ``verse''. This section pertains to blocks between +@samp{#+BEGIN_SRC} and @samp{#+END_SRC}. + +Details of Org's facilities for working with source code are described +in the following sections. + +@menu +* Features Overview:: Enjoy the versatility of source blocks. +* Structure of Code Blocks:: Code block syntax described. +* Using Header Arguments:: Different ways to set header arguments. +* Environment of a Code Block:: Arguments, sessions, working directory... +* Evaluating Code Blocks:: Place results of evaluation in the Org buffer. +* Results of Evaluation:: Choosing a results type, post-processing... +* Exporting Code Blocks:: Export contents and/or results. +* Extracting Source Code:: Create pure source code files. +* Languages:: List of supported code block languages. +* Editing Source Code:: Language major-mode editing. +* Noweb Reference Syntax:: Literate programming in Org mode. +* Library of Babel:: Use and contribute to a library of useful code blocks. +* Key bindings and Useful Functions:: Work quickly with code blocks. +* Batch Execution:: Call functions from the command line. +@end menu + +@node Features Overview +@section Features Overview + +Org can manage the source code in the block delimited by @samp{#+BEGIN_SRC} +@dots{} @samp{#+END_SRC} in several ways that can simplify housekeeping tasks +essential to modern source code maintenance. Org can edit, format, +extract, export, and publish source code blocks. Org can also compile +and execute a source code block, then capture the results. The Org +mode literature sometimes refers to source code blocks as @emph{live code} +blocks because they can alter the content of the Org document or the +material that it exports. Users can control the ``liveliness'' of each +source code block by tweaking the header arguments (see @ref{Using Header Arguments}) for compiling, execution, extraction, and exporting. + +For editing and formatting a source code block, Org uses an +appropriate Emacs major mode that includes features specifically +designed for source code in that language. + +Org can extract one or more source code blocks and write them to one +or more source files---a process known as @emph{tangling} in literate +programming terminology. + +For exporting and publishing, Org's back-ends can format a source code +block appropriately, often with native syntax highlighting. + +For executing and compiling a source code block, the user can +configure Org to select the appropriate compiler. Org provides +facilities to collect the result of the execution or compiler output, +insert it into the Org document, and/or export it. In addition to +text results, Org can insert links to other data types, including +audio, video, and graphics. Org can also link a compiler error +message to the appropriate line in the source code block. + +An important feature of Org's management of source code blocks is the +ability to pass variables, functions, and results to one another using +a common syntax for source code blocks in any language. Although most +literate programming facilities are restricted to one language or +another, Org's language-agnostic approach lets the literate programmer +match each programming task with the appropriate computer language and +to mix them all together in a single Org document. This +interoperability among languages explains why Org's source code +management facility was named @emph{Org Babel} by its originators, Eric +Schulte and Dan Davison. + +Org mode fulfills the promise of easy verification and maintenance of +publishing reproducible research by keeping text, data, code, +configuration settings of the execution environment, the results of +the execution, and associated narratives, claims, references, and +internal and external links in a single Org document. + +@node Structure of Code Blocks +@section Structure of Code Blocks + +@cindex code block, structure +@cindex source code, block structure +@cindex @samp{NAME} keyword, in source blocks +@cindex @samp{BEGIN_SRC} + +Org offers two ways to structure source code in Org documents: in +a source code block, and directly inline. Both specifications are +shown below. + +A source code block conforms to this structure: + +@example +#+NAME: +#+BEGIN_SRC
+ +#+END_SRC +@end example + +Do not be put-off by having to remember the source block syntax. Org +mode offers a command for wrapping existing text in a block (see +@ref{Structure Templates}). Org also works with other completion systems +in Emacs, some of which predate Org and have custom domain-specific +languages for defining templates. Regular use of templates reduces +errors, increases accuracy, and maintains consistency. + +@cindex source code, inline +An inline code block conforms to this structure: + +@example +src_@{@} +@end example + + +@noindent +or + +@example +src_[
]@{@} +@end example + + +@table @asis +@item @samp{#+NAME: } +Optional. Names the source block so it can be called, like +a function, from other source blocks or inline code to evaluate or +to capture the results. Code from other blocks, other files, and +from table formulas (see @ref{The Spreadsheet}) can use the name to +reference a source block. This naming serves the same purpose as +naming Org tables. Org mode requires unique names. For duplicate +names, Org mode's behavior is undefined. + +@item @samp{#+BEGIN_SRC} @dots{} @samp{#+END_SRC} +Mandatory. They mark the start and end of a block that Org +requires. The @samp{#+BEGIN_SRC} line takes additional arguments, as +described next. + +@item @samp{} +@cindex language, in code blocks +Mandatory. It is the identifier of the source code language in the +block. See @ref{Languages}, for identifiers of supported languages. + +@item @samp{} +@cindex switches, in code blocks +Optional. Switches provide finer control of the code execution, +export, and format (see the discussion of switches in @ref{Literal Examples}). + +@item @samp{
} +@cindex header arguments, in code blocks +Optional. Heading arguments control many aspects of evaluation, +export and tangling of code blocks (see @ref{Using Header Arguments}). +Using Org's properties feature, header arguments can be selectively +applied to the entire buffer or specific sub-trees of the Org +document. + +@item @samp{} +Source code in the dialect of the specified language identifier. +@end table + +@node Using Header Arguments +@section Using Header Arguments + +Org comes with many header arguments common to all languages. New +header arguments are added for specific languages as they become +available for use in source code blocks. A header argument is +specified with an initial colon followed by the argument's name in +lowercase. + +Since header arguments can be set in several ways, Org prioritizes +them in case of overlaps or conflicts by giving local settings +a higher priority. Header values in function calls, for example, +override header values from global defaults. + +@anchor{System-wide header arguments} +@subheading System-wide header arguments + +@vindex org-babel-default-header-args + +@vindex org-babel-default-header-args +System-wide values of header arguments can be specified by customizing +the @code{org-babel-default-header-args} variable, which defaults to the +following values: + +@example +:session => "none" +:results => "replace" +:exports => "code" +:cache => "no" +:noweb => "no" +@end example + +The example below sets @samp{:noweb} header arguments to @samp{yes}, which makes +Org expand @samp{:noweb} references by default. + +@lisp +(setq org-babel-default-header-args + (cons '(:noweb .

For details, see the +language-specific online documentation at +@uref{https://orgmode.org/worg/org-contrib/babel/}. + +@anchor{Header arguments in Org mode properties} +@subheading Header arguments in Org mode properties + +For header arguments applicable to the buffer, use @samp{PROPERTY} keyword +anywhere in the Org file (see @ref{Property Syntax}). + +The following example makes all the R code blocks execute in the same +session. Setting @samp{:results} to @samp{silent} ignores the results of +executions for all blocks, not just R code blocks; no results inserted +for any block. + +@example +#+PROPERTY: header-args:R :session *R* +#+PROPERTY: header-args :results silent +@end example + +@vindex org-use-property-inheritance +Header arguments set through Org's property drawers (see @ref{Property Syntax}) apply at the sub-tree level on down. Since these property +drawers can appear anywhere in the file hierarchy, Org uses outermost +call or source block to resolve the values. Org ignores +@code{org-use-property-inheritance} setting. + +In this example, @samp{:cache} defaults to @samp{yes} for all code blocks in the +sub-tree. + +@example +* sample header + :PROPERTIES: + :header-args: :cache yes + :END: +@end example + +@kindex C-c C-x p +@findex org-set-property +Properties defined through @code{org-set-property} function, bound to +@kbd{C-c C-x p}, apply to all active languages.

Blocks in +@samp{Subheading} inherit settings from @samp{Heading}. + +@anchor{Code block specific header arguments} +@subheading Code block specific header arguments + +Header arguments are most commonly set at the source code block level, +on the @samp{#+BEGIN_SRC} line. Arguments set at this level take +precedence over those set in the @code{org-babel-default-header-args} +variable, and also those set as header properties. + +In the following example, setting @samp{:results} to @samp{silent} makes it +ignore results of the code execution. Setting @samp{:exports} to @samp{code} +exports only the body of the code block to HTML or @LaTeX{}. + +@example +#+NAME: factorial +#+BEGIN_SRC haskell :results silent :exports code :var n=0 + fac 0 = 1 + fac n = n * fac (n-1) +#+END_SRC +@end example + +The same header arguments in an inline code block: + +@example +src_haskell[:exports both]@{fac 5@} +@end example + + +@cindex @samp{HEADER}, keyword +Code block header arguments can span multiple lines using @samp{#+HEADER:} +on each line.

The specifics +of variables in code blocks vary by the source language and are +covered in the language-specific documentation. The syntax for @samp{var}, +however, is the same for all languages. This includes declaring +a variable, and assigning a default value. + +The following syntax is used to pass arguments to code blocks using +the @samp{var} header argument. + +@example +:var NAME=ASSIGN +@end example + + +@noindent +@var{NAME} is the name of the variable bound in the code block +body. @var{ASSIGN} is a literal value, such as a string, +a number, a reference to a table, a list, a literal example, another +code block---with or without arguments---or the results of evaluating +a code block. @var{ASSIGN} may specify a filename for references +to elements in a different file, using a @samp{:} to separate the filename +from the reference. + +@example +:var NAME=FILE:REFERENCE +@end example + + +Here are examples of passing values by reference: + +@table @asis +@item table +A table named with a @samp{NAME} keyword. + +@example +#+NAME: example-table +| 1 | +| 2 | +| 3 | +| 4 | + +#+NAME: table-length +#+BEGIN_SRC emacs-lisp :var table=example-table + (length table) +#+END_SRC + +#+RESULTS: table-length +: 4 +@end example + +When passing a table, you can treat specially the row, or the +column, containing labels for the columns, or the rows, in the +table. + +@cindex @samp{colnames}, header argument +The @samp{colnames} header argument accepts @samp{yes}, @samp{no}, or @samp{nil} values. +The default value is @samp{nil}: if an input table has column +names---because the second row is a horizontal rule---then Org +removes the column names, processes the table, puts back the column +names, and then writes the table to the results block. Using @samp{yes}, +Org does the same to the first row, even if the initial table does +not contain any horizontal rule. When set to @samp{no}, Org does not +pre-process column names at all. + +@example +#+NAME: less-cols +| a | +|---| +| b | +| c | + +#+BEGIN_SRC python :var tab=less-cols :colnames nil + return [[val + '*' for val in row] for row in tab] +#+END_SRC + +#+RESULTS: +| a | +|----| +| b* | +| c* | +@end example + +@cindex @samp{rownames}, header argument +Similarly, the @samp{rownames} header argument can take two values: @samp{yes} +or @samp{no}. When set to @samp{yes}, Org removes the first column, processes +the table, puts back the first column, and then writes the table to +the results block. The default is @samp{no}, which means Org does not +pre-process the first column. Note that Emacs Lisp code blocks +ignore @samp{rownames} header argument because of the ease of +table-handling in Emacs. + +@example +#+NAME: with-rownames +| one | 1 | 2 | 3 | 4 | 5 | +| two | 6 | 7 | 8 | 9 | 10 | + +#+BEGIN_SRC python :var tab=with-rownames :rownames yes + return [[val + 10 for val in row] for row in tab] +#+END_SRC + +#+RESULTS: +| one | 11 | 12 | 13 | 14 | 15 | +| two | 16 | 17 | 18 | 19 | 20 | +@end example +@end table + +To refer to a table in another file, join the filename and table name with +a colon, for example: @samp{:var table=other-file.org:example-table}. + +@table @asis +@item list +A simple named list. + +@example +#+NAME: example-list +- simple + - not + - nested +- list + +#+BEGIN_SRC emacs-lisp :var x=example-list + (print x) +#+END_SRC + +#+RESULTS: +| simple | list | +@end example + +Note that only the top level list items are passed along.

Note that this indexing occurs +@emph{before} other table-related header arguments are applied, such as +@samp{hlines}, @samp{colnames} and @samp{rownames}. The following example assigns +the last cell of the first row the table @samp{example-table} to the +variable @samp{data}: + +@example +#+NAME: example-table +| 1 | a | +| 2 | b | +| 3 | c | +| 4 | d | + +#+BEGIN_SRC emacs-lisp :var data=example-table[0,-1] + data +#+END_SRC + +#+RESULTS: +: a +@end example + +Two integers separated by a colon reference a range of variable +values.

You need to take them into account, even when @samp{colnames} or +@samp{rownames} header arguments remove them. + +Emacs lisp code can also set the values for variables. To +differentiate a value from Lisp code, Org interprets any value +starting with @samp{(}, @samp{[}, @samp{'} or @samp{`} as Emacs Lisp code. The result of +evaluating that code is then assigned to the value of that variable. +The following example shows how to reliably query and pass the file +name of the Org mode buffer to a code block using headers. We need +reliability here because the file's name could change once the code in +the block starts executing. + +@example +#+BEGIN_SRC sh :var filename=(buffer-file-name) :exports both + wc -w $filename +#+END_SRC +@end example + +Note that values read from tables and lists are not mistakenly +evaluated as Emacs Lisp code, as illustrated in the following example. + +@example +#+NAME: table +| (a b c) | + +#+HEADER: :var data=table[0,0] +#+BEGIN_SRC perl + $data +#+END_SRC + +#+RESULTS: +: (a b c) +@end example + +@anchor{Using sessions} +@subheading Using sessions + +@cindex using sessions in code blocks +@cindex @samp{session}, header argument +Two code blocks can share the same environment. The @samp{session} header +argument is for running multiple source code blocks under one session. +Org runs code blocks with the same session name in the same +interpreter process. + +@table @asis +@item @samp{none} +Default. Each code block gets a new interpreter process to execute. +The process terminates once the block is evaluated. + +@item @var{STRING} +Any string besides @samp{none} turns that string into the name of that +session. For example, @samp{:session STRING} names it @samp{STRING}. If +@samp{session} has no value, then the session name is derived from the +source language identifier. Subsequent blocks with the same source +code language use the same session. Depending on the language, +state variables, code from other blocks, and the overall interpreted +environment may be shared. Some interpreted languages support +concurrent sessions when subsequent source code language blocks +change session names. +@end table + +Only languages that provide interactive evaluation can have session +support. Not all languages provide this support, such as C and ditaa. +Even languages, such as Python and Haskell, that do support +interactive evaluation impose limitations on allowable language +constructs that can run interactively.

Under the surface, @samp{dir} simply sets the value of the Emacs +variable @code{default-directory}.

Org may use a specific escape +character in some situations, i.e., a backslash in macros (see @ref{Macro Replacement}) and links (see @ref{Link Format}), or a comma in source and +example blocks (see @ref{Literal Examples}). In the general case, however, +we suggest to use the zero width space.

Each source code +block, in terms of risk, is equivalent to an executable file. Org +therefore puts a few confirmation prompts by default. This is to +alert the casual user from accidentally running untrusted code. + +For users who do not run code blocks or write code regularly, Org's +default settings should suffice. However, some users may want to +tweak the prompts for fewer interruptions. To weigh the risks of +automatic execution of code blocks, here are some details about code +evaluation. + +Org evaluates code in the following circumstances: + +@table @asis +@item @emph{Source code blocks} +Org evaluates source code blocks in an Org file during export. Org +also evaluates a source code block with the @kbd{C-c C-c} key +chord. Users exporting or running code blocks must load files only +from trusted sources. Be wary of customizing variables that remove +or alter default security measures. + +@defopt org-confirm-babel-evaluate +When @code{t}, Org prompts the user for confirmation before executing +each code block. When @code{nil}, Org executes code blocks without +prompting the user for confirmation. When this option is set to +a custom function, Org invokes the function with these two +arguments: the source code language and the body of the code block. +The custom function must return either a @code{t} or @code{nil}, which +determines if the user is prompted. Each source code language can +be handled separately through this function argument. +@end defopt + +For example, here is how to execute ditaa code blocks without +prompting: + +@lisp +(defun my-org-confirm-babel-evaluate (lang body) + (not (string= lang "ditaa"))) ;don't ask for ditaa +(setq org-confirm-babel-evaluate #'my-org-confirm-babel-evaluate) +@end lisp + +@item @emph{Following @samp{shell} and @samp{elisp} links} +Org has two link types that can directly evaluate code (see +@ref{External Links}).

This would be hard to do in a general way without +complicated customization nightmares. Moreover, that would take Org +away from its simplicity roots that Orgtbl has proven. There is, +however, an alternate approach to accomplishing the same. + +This approach involves implementing a custom @emph{translate} function that +operates on a native Org @emph{source table} to produce a table in another +format. This strategy would keep the excellently working Orgtbl +simple and isolate complications, if any, confined to the translate +function. To add more alien table formats, we just add more translate +functions. Also the burden of developing custom translate functions +for new table formats is in the hands of those who know those formats +best. + +@menu +* Radio tables:: Sending and receiving radio tables. +* A @LaTeX{} example:: Step by step, almost a tutorial. +* Translator functions:: Copy and modify. +@end menu + +@node Radio tables +@appendixsubsec Radio tables + +@cindex radio tables + +Radio tables are target locations for translated tables that are not near +their source. Org finds the target location and inserts the translated +table. + +The key to finding the target location is the magic words @samp{BEGIN/END +RECEIVE ORGTBL}. They have to appear as comments in the current mode. +If the mode is C, then: + +@example +/* BEGIN RECEIVE ORGTBL table_name */ +/* END RECEIVE ORGTBL table_name */ +@end example + +At the location of source, Org needs a special line to direct Orgtbl +to translate and to find the target for inserting the translated +table. For example: + +@cindex @samp{ORGTBL}, keyword +@example +#+ORGTBL: SEND table_name translation_function arguments ... +@end example + + +@noindent +@samp{table_name} is the table's reference name, which is also used in the +receiver lines, and the @samp{translation_function} is the Lisp function +that translates. This line, in addition, may also contain alternating +key and value arguments at the end. The translation function gets +these values as a property list. A few standard parameters are +already recognized and acted upon before the translation function is +called: + +@table @asis +@item @samp{:skip N} +Skip the first N lines of the table. Hlines do count; include them +if they are to be skipped. + +@item @samp{:skipcols (n1 n2 ...)} +List of columns to be skipped. First Org automatically discards +columns with calculation marks and then sends the table to the +translator function, which then skips columns as specified in +@samp{skipcols}. +@end table + +To keep the source table intact in the buffer without being disturbed +when the source file is compiled or otherwise being worked on, use one +of these strategies: + +@itemize +@item +Place the table in a block comment. For example, in C mode you +could wrap the table between @samp{/*} and @samp{*/} lines. + +@item +Put the table after an ``end'' statement. For example @code{\bye} in @TeX{} +and @code{\end@{document@}} in @LaTeX{}. + +@item +Comment and un-comment each line of the table during edits.

Orgtbl mode inserts +a radio table skeleton@footnote{By default this works only for @LaTeX{}, HTML, and Texinfo. +Configure the variable @code{orgtbl-radio-table-templates} to install +templates for other modes.} with the command @kbd{M-x orgtbl-insert-radio-table}, which prompts for a table name.

I was trying to organize my notes and +projects, and using Emacs seemed to be the natural way to go. +However, having to remember eleven different commands with two or +three keys per command, only to hide and show parts of the outline +tree, that seemed entirely unacceptable to me. Also, when using +outlines to take notes, I constantly wanted to restructure the tree, +organizing it parallel to my thoughts and plans. @emph{Visibility cycling} +and @emph{structure editing} were originally implemented in the package +@samp{outline-magic.el}, but quickly moved to the more general @samp{org.el}. +As this environment became comfortable for project planning, the next +step was adding @emph{TODO entries}, basic @emph{timestamps}, and @emph{table +support}. These areas highlighted the two main goals that Org still +has today: to be a new, outline-based, plain text mode with innovative +and intuitive editing features, and to incorporate project planning +functionality directly into a notes file. + +Since the first release, literally thousands of emails to me or to the +@email{emacs-orgmode@@gnu.org, mailing list} have provided a constant stream of bug reports, feedback, +new ideas, and sometimes patches and add-on code. Many thanks to +everyone who has helped to improve this package. I am trying to keep +here a list of the people who had significant influence in shaping one +or more aspects of Org. The list may not be complete, if I have +forgotten someone, please accept my apologies and let me know. + +Before I get to this list, a few special mentions are in order: + +@table @asis +@item Bastien Guerry +Bastien has written a large number of extensions to Org (most of +them integrated into the core by now), including the @LaTeX{} exporter +and the plain list parser. His support during the early days was +central to the success of this project. Bastien also invented Worg, +helped establishing the Web presence of Org, and sponsored hosting +costs for the orgmode.org website. Bastien stepped in as maintainer +of Org between 2011 and 2013, at a time when I desperately needed +a break. + +@item Eric Schulte and Dan Davison +Eric and Dan are jointly responsible for the Org Babel system, which +turns Org into a multi-language environment for evaluating code and +doing literate programming and reproducible research. This has +become one of Org's killer features that define what Org is today. + +@item John Wiegley +John has contributed a number of great ideas and patches directly to +Org, including the attachment system (@samp{org-attach.el}), integration +with Apple Mail (@samp{org-mac-message.el}), hierarchical dependencies of +TODO items, habit tracking (@samp{org-habits.el}), and encryption +(@samp{org-crypt.el}). Also, the capture system is really an extended +copy of his great @samp{remember.el}. + +@item Sebastian Rose +Without Sebastian, the HTML/XHTML publishing of Org would be the +pitiful work of an ignorant amateur. Sebastian has pushed this part +of Org onto a much higher level. He also wrote @samp{org-info.js}, +a JavaScript program for displaying webpages derived from Org using +an Info-like or a folding interface with single-key navigation. +@end table + +See below for the full list of contributions! Again, please let me +know what I am missing here! + +@anchor{From Bastien} +@appendixsec From Bastien + +I (Bastien) have been maintaining Org between 2011 and 2013. This +appendix would not be complete without adding a few more +acknowledgments and thanks. + +I am first grateful to Carsten for his trust while handing me over the +maintainership of Org. His unremitting support is what really helped +me getting more confident over time, with both the community and the +code. + +When I took over maintainership, I knew I would have to make Org more +collaborative than ever, as I would have to rely on people that are +more knowledgeable than I am on many parts of the code. Here is +a list of the persons I could rely on, they should really be +considered co-maintainers, either of the code or the community: + +@table @asis +@item Eric Schulte +Eric is maintaining the Babel parts of Org. His reactivity here +kept me away from worrying about possible bugs here and let me focus +on other parts. + +@item Nicolas Goaziou +Nicolas is maintaining the consistency of the deepest parts of Org. +His work on @samp{org-element.el} and @samp{ox.el} has been outstanding, and +it opened the doors for many new ideas and features. He rewrote +many of the old exporters to use the new export engine, and helped +with documenting this major change. More importantly (if that's +possible), he has been more than reliable during all the work done +for Org 8.0, and always very reactive on the mailing list. + +@item Achim Gratz +Achim rewrote the building process of Org, turning some @emph{ad hoc} +tools into a flexible and conceptually clean process. He patiently +coped with the many hiccups that such a change can create for users. + +@item Nick Dokos +The Org mode mailing list would not be such a nice place without +Nick, who patiently helped users so many times. It is impossible to +overestimate such a great help, and the list would not be so active +without him. +@end table + +I received support from so many users that it is clearly impossible to +be fair when shortlisting a few of them, but Org's history would not +be complete if the ones above were not mentioned in this manual. + +@anchor{List of Contributions} +@appendixsec List of Contributions + +@itemize +@item +Russell Adams came up with the idea for drawers. + +@item +Thomas Baumann wrote @samp{ol-bbdb.el} and @samp{ol-mhe.el}. + +@item +Christophe Bataillon created the great unicorn logo that we use on +the Org mode website. + +@item +Alex Bochannek provided a patch for rounding timestamps. + +@item +Jan Böcker wrote @samp{ol-docview.el}. + +@item +Brad Bozarth showed how to pull RSS feed data into Org files. + +@item +Tom Breton wrote @samp{org-choose.el}. + +@item +Charles Cave's suggestion sparked the implementation of templates +for Remember, which are now templates for capture. + +@item +Timothy E Chapman worked on a complete overhaul of the orgmode.org +website in 2020 and helped fixing various bugs. + +@item +Pavel Chalmoviansky influenced the agenda treatment of items with +specified time. + +@item +Gregory Chernov patched support for Lisp forms into table +calculations and improved XEmacs compatibility, in particular by +porting @samp{nouline.el} to XEmacs. + +@item +Sacha Chua suggested copying some linking code from Planner. + +@item +Baoqiu Cui contributed the DocBook exporter. + +@item +Eddward DeVilla proposed and tested checkbox statistics.

But this License is not limited to +software manuals; it can be used for any textual work, regardless +of subject matter or whether it is published as a printed book. We +recommend this License principally for works whose purpose is +instruction or reference. + +@item +APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, +that contains a notice placed by the copyright holder saying it can +be distributed under the terms of this License. Such a notice +grants a world-wide, royalty-free license, unlimited in duration, +to use that work under the conditions stated herein. The +``Document'', below, refers to any such manual or work. Any member +of the public is a licensee, and is addressed as ``you''. You accept +the license if you copy, modify or distribute the work in a way +requiring permission under copyright law. + +A ``Modified Version'' of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A ``Secondary Section'' is a named appendix or a front-matter section +of the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall +subject (or to related matters) and contains nothing that could +fall directly within that overall subject. (Thus, if the Document +is in part a textbook of mathematics, a Secondary Section may not +explain any mathematics.) The relationship could be a matter of +historical connection with the subject or with related matters, or +of legal, commercial, philosophical, ethical or political position +regarding them. + +The ``Invariant Sections'' are certain Secondary Sections whose +titles are designated, as being those of Invariant Sections, in the +notice that says that the Document is released under this License. +If a section does not fit the above definition of Secondary then it +is not allowed to be designated as Invariant. The Document may +contain zero Invariant Sections. If the Document does not identify +any Invariant Sections then there are none. + +The ``Cover Texts'' are certain short passages of text that are +listed, as Front-Cover Texts or Back-Cover Texts, in the notice +that says that the Document is released under this License. +A Front-Cover Text may be at most 5 words, and a Back-Cover Text +may be at most 25 words. + +A ``Transparent'' copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed +of pixels) generic paint programs or (for drawings) some widely +available drawing editor, and that is suitable for input to text +formatters or for automatic translation to a variety of formats +suitable for input to text formatters. A copy made in an otherwise +Transparent file format whose markup, or absence of markup, has +been arranged to thwart or discourage subsequent modification by +readers is not Transparent. An image format is not Transparent if +used for any substantial amount of text. A copy that is not +``Transparent'' is called ``Opaque''. + +Examples of suitable formats for Transparent copies include plain +ASCII without markup, Texinfo input format, @LaTeX{} input format, +SGML or XML using a publicly available DTD, and standard-conforming +simple HTML, PostScript or PDF designed for human modification. +Examples of transparent image formats include PNG, XCF and JPG@. +Opaque formats include proprietary formats that can be read and +edited only by proprietary word processors, SGML or XML for which +the DTD and/or processing tools are not generally available, and +the machine-generated HTML, PostScript or PDF produced by some word +processors for output purposes only. + +The ``Title Page'' means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the +material this License requires to appear in the title page. For +works in formats which do not have any title page as such, ``Title +Page'' means the text near the most prominent appearance of the +work's title, preceding the beginning of the body of the text. + +The ``publisher'' means any person or entity that distributes copies +of the Document to the public. + +A section ``Entitled XYZ'' means a named subunit of the Document +whose title either is precisely XYZ or contains XYZ in parentheses +following text that translates XYZ in another language. (Here XYZ +stands for a specific section name mentioned below, such as +``Acknowledgements'', ``Dedications'', ``Endorsements'', or ``History''.) +To ``Preserve the Title'' of such a section when you modify the +Document means that it remains a section ``Entitled XYZ'' according +to this definition. + +The Document may include Warranty Disclaimers next to the notice +which states that this License applies to the Document. These +Warranty Disclaimers are considered to be included by reference in +this License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and +has no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License +applies to the Document are reproduced in all copies, and that you +add no other conditions whatsoever to those of this License. You +may not use technical measures to obstruct or control the reading +or further copying of the copies you make or distribute. However, +you may accept compensation in exchange for copies. If you +distribute a large enough number of copies you must also follow the +conditions in section 3. + +You may also lend copies, under the same conditions stated above, +and you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly +have printed covers) of the Document, numbering more than 100, and +the Document's license notice requires Cover Texts, you must +enclose the copies in covers that carry, clearly and legibly, all +these Cover Texts: Front-Cover Texts on the front cover, and +Back-Cover Texts on the back cover. Both covers must also clearly +and legibly identify you as the publisher of these copies. The +front cover must present the full title with all words of the title +equally prominent and visible. You may add other material on the +covers in addition. Copying with changes limited to the covers, as +long as they preserve the title of the Document and satisfy these +conditions, can be treated as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto +adjacent pages. + +If you publish or distribute Opaque copies of the Document +numbering more than 100, you must either include a machine-readable +Transparent copy along with each Opaque copy, or state in or with +each Opaque copy a computer-network location from which the general +network-using public has access to download using public-standard +network protocols a complete Transparent copy of the Document, free +of added material. If you use the latter option, you must take +reasonably prudent steps, when you begin distribution of Opaque +copies in quantity, to ensure that this Transparent copy will +remain thus accessible at the stated location until at least one +year after the last time you distribute an Opaque copy (directly or +through your agents or retailers) of that edition to the public. + +It is requested, but not required, that you contact the authors of +the Document well before redistributing any large number of copies, +to give them a chance to provide you with an updated version of the +Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document +under the conditions of sections 2 and 3 above, provided that you +release the Modified Version under precisely this License, with the +Modified Version filling the role of the Document, thus licensing +distribution and modification of the Modified Version to whoever +possesses a copy of it. In addition, you must do these things in +the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title +distinct from that of the Document, and from those of previous +versions (which should, if there were any, be listed in the +History section of the Document). You may use the same title as +a previous version if the original publisher of that version +gives permission. + +@item +List on the Title Page, as authors, one or more persons or +entities responsible for authorship of the modifications in the +Modified Version, together with at least five of the principal +authors of the Document (all of its principal authors, if it has +fewer than five), unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license +notice giving the public permission to use the Modified Version +under the terms of this License, in the form shown in the +Addendum below. + +@item +Preserve in that license notice the full lists of Invariant +Sections and required Cover Texts given in the Document's +license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and +add to it an item stating at least the title, year, new authors, +and publisher of the Modified Version as given on the Title +Page. If there is no section Entitled ``History'' in the Document, +create one stating the title, year, authors, and publisher of +the Document as given on its Title Page, then add an item +describing the Modified Version as stated in the previous +sentence. + +@item +Preserve the network location, if any, given in the Document +for public access to a Transparent copy of the Document, and +likewise the network locations given in the Document for +previous versions it was based on. These may be placed in the +``History'' section. You may omit a network location for a work +that was published at least four years before the Document +itself, or if the original publisher of the version it refers +to gives permission. + +@item +For any section Entitled ``Acknowledgements'' or ``Dedications'', +Preserve the Title of the section, and preserve in the section +all the substance and tone of each of the contributor +acknowledgements and/or dedications given therein. + +@item +Preserve all the Invariant Sections of the Document, unaltered +in their text and in their titles. Section numbers or the +equivalent are not considered part of the section titles. + +@item +Delete any section Entitled ``Endorsements''. Such a section may +not be included in the Modified Version. + +@item +Do not retitle any existing section to be Entitled +``Endorsements'' or to conflict in title with any Invariant +Section. + +@item +Preserve any Warranty Disclaimers. +@end enumerate + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled ``Endorsements'', provided it contains +nothing but endorsements of your Modified Version by various +parties---for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + +@item +COMBINING DOCUMENTS + +You may combine the Document with other documents released under +this License, under the terms defined in section 4 above for +modified versions, provided that you include in the combination all +of the Invariant Sections of all of the original documents, +unmodified, and list them all as Invariant Sections of your +combined work in its license notice, and that you preserve all +their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name +but different contents, make the title of each such section unique +by adding at the end of it, in parentheses, the name of the +original author or publisher of that section if known, or else +a unique number. Make the same adjustment to the section titles in +the list of Invariant Sections in the license notice of the +combined work. + +In the combination, you must combine any sections Entitled +``History'' in the various original documents, forming one section +Entitled ``History''; likewise combine any sections Entitled +``Acknowledgements'', and any sections Entitled ``Dedications''. You +must delete all sections Entitled ``Endorsements.'' + +@item +COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other +documents released under this License, and replace the individual +copies of this License in the various documents with a single copy +that is included in the collection, provided that you follow the +rules of this License for verbatim copying of each of the documents +in all other respects. + +You may extract a single document from such a collection, and +distribute it individually under this License, provided you insert +a copy of this License into the extracted document, and follow this +License in all other respects regarding verbatim copying of that +document. + +@item +AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other +separate and independent documents or works, in or on a volume of +a storage or distribution medium, is called an ``aggregate'' if the +copyright resulting from the compilation is not used to limit the +legal rights of the compilation's users beyond what the individual +works permit. When the Document is included in an aggregate, this +License does not apply to the other works in the aggregate which +are not themselves derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half +of the entire aggregate, the Document's Cover Texts may be placed +on covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic +form. Otherwise they must appear on printed covers that bracket +the whole aggregate. + +@item +TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of +section 4. Replacing Invariant Sections with translations requires +special permission from their copyright holders, but you may +include translations of some or all Invariant Sections in addition +to the original versions of these Invariant Sections.

It contains all basic features and commands, along with +important hints for customization. It is intended for beginners who +would shy back from a 200 pages manual because of sheer size. + +@anchor{Installation} +@heading Installation + +@quotation Important +If you are using a version of Org that is part of the Emacs +distribution, please skip this section and go directly to @ref{Activation}. + +@end quotation + +If you have downloaded Org from the web, either as a distribution +@samp{.zip} or @samp{.tar} file, or as a Git archive, it is best to run it +directly from the distribution directory. You need to add the @samp{lisp/} +subdirectories to the Emacs load path. To do this, add the following +line to your Emacs init file: + +@example +(add-to-list 'load-path "~/path/to/orgdir/lisp") +@end example + + +@noindent +If you have been using git or a tar ball to get Org, you need to run +the following command to generate autoload information. + +@example +make autoloads +@end example + +@anchor{Activation} +@heading Activation + +Add the following lines to your Emacs init file to define @emph{global} +keys for three commands that are useful in any Emacs buffer, not just +Org buffers. Please choose suitable keys yourself. + +@lisp +(global-set-key (kbd "C-c l") #'org-store-link) +(global-set-key (kbd "C-c a") #'org-agenda) +(global-set-key (kbd "C-c c") #'org-capture) +@end lisp + +Files with extension @samp{.org} will be put into Org mode automatically. + +@anchor{Feedback} +@heading Feedback + +If you find problems with Org, or if you have questions, remarks, or +ideas about it, please mail to the Org mailing list +@email{emacs-orgmode@@gnu.org}. For information on how to submit bug +reports, see the main manual. + +@node Document Structure +@chapter Document Structure + +Org is an outliner. Outlines allow a document to be organized in +a hierarchical structure, which, least for me, is the best +representation of notes and thoughts. An overview of this structure +is achieved by folding, i.e., hiding large parts of the document to +show only the general document structure and the parts currently being +worked on. Org greatly simplifies the use of outlines by compressing +the entire show and hide functionalities into a single command, +@code{org-cycle}, which is bound to the @kbd{@key{TAB}} key. + +@menu +* Headlines:: How to typeset Org tree nodes. +* Visibility Cycling:: Show and hide, much simplified. +* Motion:: Jumping to other headlines. +* Structure Editing:: Changing sequence and level of headlines. +* Sparse Trees:: Matches embedded in context. +* Plain Lists:: Additional structure within an entry. +@end menu + +@node Headlines +@section Headlines + +Headlines define the structure of an outline tree. The headlines in +Org start on the left margin@footnote{See the variable @code{org-special-ctrl-a/e} to configure special +behavior of @kbd{C-a} and @kbd{C-e} in headlines.} with one or more stars followed by +a space. For example: + +@example +* Top level headline +** Second level +*** Third level + some text +*** Third level + more text +* Another top level headline +@end example + +Note that a headline named after @code{org-footnote-section}, which +defaults to @samp{Footnotes}, is considered as special. A subtree with +this headline will be silently ignored by exporting functions. + +Some people find the many stars too noisy and would prefer an outline +that has whitespace followed by a single star as headline starters. +See @ref{Miscellaneous} for a setup to realize this. + +@node Visibility Cycling +@section Visibility Cycling + +Outlines make it possible to hide parts of the text in the buffer. +Org uses just two commands, bound to @kbd{@key{TAB}} and +@{@{@{kbd@{S-TAB)@}@}@} to change the visibility in the buffer. + +@table @asis +@item @kbd{@key{TAB}} +@emph{Subtree cycling}: Rotate current subtree among the states + +@example +,-> FOLDED -> CHILDREN -> SUBTREE --. +'-----------------------------------' +@end example + + +When called with a prefix argument (@kbd{C-u @key{TAB}}), or with the +Shift key, global cycling is invoked. + +@item @kbd{S-@key{TAB}} +@itemx @kbd{C-u @key{TAB}} +@emph{Global cycling}: Rotate the entire buffer among the states + +@example +,-> OVERVIEW -> CONTENTS -> SHOW ALL --. +'--------------------------------------' +@end example + +@item @kbd{C-u C-u C-u @key{TAB}} +Show all, including drawers. +@end table + +When Emacs first visits an Org file, the global state is set to +OVERVIEW, i.e., only the top level headlines are visible. This can be +configured through the variable @code{org-startup-folded}, or on a per-file +basis by adding a @samp{STARTUP} keyword to @samp{overview}, @samp{content}, +@samp{showall}, @samp{showeverything} or @samp{showlevels} (n = 2..5) like this: + +@example +#+STARTUP: content +@end example + +@node Motion +@section Motion + +The following commands jump to other headlines in the buffer. + +@table @asis +@item @kbd{C-c C-n} +Next heading. + +@item @kbd{C-c C-p} +Previous heading. + +@item @kbd{C-c C-f} +Next heading same level. + +@item @kbd{C-c C-b} +Previous heading same level. + +@item @kbd{C-c C-u} +Backward to higher level heading. +@end table + +@node Structure Editing +@section Structure Editing + +@table @asis +@item @kbd{M-@key{RET}} +Insert new heading with same level as current. If point is in +a plain list item, a new item is created (see @ref{Plain Lists}). When +this command is used in the middle of a line, the line is split and +the rest of the line becomes the new headline@footnote{If you do not want the line to be split, customize the variable +@code{org-M-RET-may-split-line}.}. + +@item @kbd{M-S-@key{RET}} +Insert new TODO entry with same level as current heading. + +@item @kbd{@key{TAB}} in new +@itemx empty entry +In a new entry with no text yet, @kbd{@key{TAB}} cycles through +reasonable levels. + +@item @kbd{M-@key{LEFT}} +@itemx @kbd{M-@key{RIGHT}} +Promote or demote current heading by one level. + +@item @kbd{M-@key{UP}} +@itemx @kbd{M-@key{DOWN}} +Move subtree up or down, i.e., swap with previous or next subtree of +same level. + +@item @kbd{C-c C-w} +Refile entry or region to a different location. See @ref{Refile and Copy}. + +@item @kbd{C-x n s} +@itemx @kbd{C-x n w} +Narrow buffer to current subtree and widen it again. +@end table + +When there is an active region (Transient Mark mode), promotion and +demotion work on all headlines in the region. + +@node Sparse Trees +@section Sparse Trees + +An important feature of Org mode is the ability to construct @emph{sparse +trees} for selected information in an outline tree, so that the entire +document is folded as much as possible, but the selected information +is made visible along with the headline structure above it@footnote{See also the variable @code{org-show-context-detail} to decide how +much context is shown around each match.}. +Just try it out and you will see immediately how it works. + +Org mode contains several commands creating such trees, all these +commands can be accessed through a dispatcher: + +@table @asis +@item @kbd{C-c /} +This prompts for an extra key to select a sparse-tree creating +command. + +@item @kbd{C-c / r} +Occur. Prompts for a regexp and shows a sparse tree with all +matches. Each match is also highlighted; the highlights disappear +by pressing @kbd{C-c C-c}. + +The other sparse tree commands select headings based on TODO +keywords, tags, or properties and will be discussed later in this +manual. +@end table + +@node Plain Lists +@section Plain Lists + +Within an entry of the outline tree, hand-formatted lists can provide +additional structure. They also provide a way to create lists of +checkboxes (see @ref{Checkboxes}). Org supports editing such lists, and +every exporter (see @ref{Exporting}) can parse and format them. + +Org knows ordered lists, unordered lists, and description lists. + +@itemize +@item +@emph{Unordered} list items start with @samp{-}, @samp{+}, or @samp{*} as bullets. + +@item +@emph{Ordered} list items start with @samp{1.}, or @samp{1)}. + +@item +@emph{Description} list use @samp{::} to separate the @emph{term} from the +description. +@end itemize + +Items belonging to the same list must have the same indentation on the +first line. An item ends before the next line that is indented like +its bullet/number, or less. A list ends when all items are closed, or +before two blank lines. An example: + +@example +* Lord of the Rings + My favorite scenes are (in this order) + 1. The attack of the Rohirrim + 2. Eowyn's fight with the witch king + + this was already my favorite scene in the book + + I really like Miranda Otto. + Important actors in this film are: + - Elijah Wood :: He plays Frodo + - Sean Astin :: He plays Sam, Frodo's friend. +@end example + +The following commands act on items when point is in the first line of +an item (the line with the bullet or number). + +@table @asis +@item @kbd{@key{TAB}} +Items can be folded just like headline levels. + +@item @kbd{M-@key{RET}} +Insert new item at current level. With a prefix argument, force +a new heading (see @ref{Structure Editing}). + +@item @kbd{M-S-@key{RET}} +Insert a new item with a checkbox (see @ref{Checkboxes}). + +@item @kbd{M-S-@key{UP}} +@itemx @kbd{M-S-@key{DOWN}} +Move the item including subitems up/down (swap with previous/next +item of same indentation). If the list is ordered, renumbering is +automatic. + +@item @kbd{M-@key{LEFT}} +@itemx @kbd{M-@key{RIGHT}} +Decrease/increase the indentation of an item, leaving children +alone. + +@item @kbd{M-S-@key{LEFT}} +@itemx @kbd{M-S-@key{RIGHT}} +Decrease/increase the indentation of the item, including subitems. + +@item @kbd{C-c C-c} +If there is a checkbox (see @ref{Checkboxes}) in the item line, toggle +the state of the checkbox. Also verify bullets and indentation +consistency in the whole list. + +@item @kbd{C-c -} +Cycle the entire list level through the different itemize/enumerate +bullets (@samp{-}, @samp{+}, @samp{*}, @samp{1.}, @samp{1)}). +@end table + +@node Tables +@chapter Tables + +Org comes with a fast and intuitive table editor. Spreadsheet-like +calculations are supported in connection with the Emacs Calc package +(see @ref{Top,GNU Emacs Calculator Manual,,calc,}). + +Org makes it easy to format tables in plain ASCII@. Any line with @samp{|} +as the first non-whitespace character is considered part of a table. +@samp{|} is also the column separator. A table might look like this: + +@example +| Name | Phone | Age | +|-------+-------+-----| +| Peter | 1234 | 17 | +| Anna | 4321 | 25 | +@end example + +A table is re-aligned automatically each time you press @kbd{@key{TAB}} +or @kbd{@key{RET}} or @kbd{C-c C-c} inside the table. +@kbd{@key{TAB}} also moves to the next field (@kbd{@key{RET}} to the +next row) and creates new table rows at the end of the table or before +horizontal lines. The indentation of the table is set by the first +line. Any line starting with @samp{|-} is considered as a horizontal +separator line and will be expanded on the next re-align to span the +whole table width. So, to create the above table, you would only type + +@example +|Name|Phone|Age| +|- +@end example + + +@noindent +and then press @kbd{@key{TAB}} to align the table and start filling in +fields. Even faster would be to type @samp{|Name|Phone|Age} followed by +@kbd{C-c @key{RET}}. + +When typing text into a field, Org treats @kbd{DEL}, +@kbd{Backspace}, and all character keys in a special way, so that +inserting and deleting avoids shifting other fields. Also, when +typing @emph{immediately after point was moved into a new field with +@kbd{@key{TAB}}, @kbd{S-@key{TAB}} or @kbd{@key{RET}}}, the field is +automatically made blank. + +@anchor{Creation and conversion} +@heading Creation and conversion + +@table @asis +@item @kbd{C-c |} +Convert the active region to table. If every line contains at least +one @kbd{@key{TAB}} character, the function assumes that the material +is tab separated. If every line contains a comma, comma-separated +values (CSV) are assumed. If not, lines are split at whitespace +into fields. + +If there is no active region, this command creates an empty Org +table. But it is easier just to start typing, like @kbd{| N a m e | P h o n e | A g e @key{RET} | - @key{TAB}}. +@end table + +@anchor{Re-aligning and field motion} +@heading Re-aligning and field motion + +@table @asis +@item @kbd{C-c C-c} +Re-align the table without moving point. + +@item @kbd{@key{TAB}} +Re-align the table, move to the next field.

With a prefix argument, the +line is created below the current one. + +@item @kbd{C-c -} +Insert a horizontal line below current row. With a prefix argument, +the line is created above the current line. + +@item @kbd{C-c @key{RET}} +Insert a horizontal line below current row, and move the point into +the row below that line. + +@item @kbd{C-c ^} +Sort the table lines in the region. The position of point indicates +the column to be used for sorting, and the range of lines is the +range between the nearest horizontal separator lines, or the entire +table. +@end table + +@node Hyperlinks +@chapter Hyperlinks + +Like HTML, Org provides links inside a file, external links to other +files, Usenet articles, emails, and much more. + +Org recognizes plain URIs, possibly wrapped within angle brackets, and +activate them as clickable links. The general link format, however, +looks like this: + +@example +[[LINK][DESCRIPTION]] +@end example + + +@noindent +or alternatively + +@example +[[LINK]] +@end example + + +Once a link in the buffer is complete, with all brackets present, Org +changes the display so that @samp{DESCRIPTION} is displayed instead of +@samp{[[LINK][DESCRIPTION]]} and @samp{LINK} is displayed instead of @samp{[[LINK]]}. +To edit the invisible @var{LINK} part, use @kbd{C-c C-l} +with the point on the link. + +@anchor{Internal links} +@heading Internal links + +If the link does not look like a URL, it is considered to be internal +in the current file. The most important case is a link like +@samp{[[#my-custom-id]]} which links to the entry with the @samp{CUSTOM_ID} property +@samp{my-custom-id}. + +Links such as @samp{[[My Target]]} or @samp{[[My Target][Find my target]]} lead +to a text search in the current file for the corresponding target, +which looks like @samp{<>}. + +@anchor{External Links} +@heading External Links + +Org supports links to files, websites, Usenet and email messages, BBDB +database entries and links to both IRC conversations and their logs. +External links are URL-like locators. They start with a short +identifying string followed by a colon. There can be no space after +the colon. Here are some examples: + +@multitable {aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa} {aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa} +@item @samp{http://www.astro.uva.nl/=dominik} +@tab on the web +@item @samp{file:/home/dominik/images/jupiter.jpg} +@tab file, absolute path +@item @samp{/home/dominik/images/jupiter.jpg} +@tab same as above +@item @samp{file:papers/last.pdf} +@tab file, relative path +@item @samp{./papers/last.pdf} +@tab same as above +@item @samp{file:projects.org} +@tab another Org file +@item @samp{docview:papers/last.pdf::NNN} +@tab open in DocView mode at page @var{NNN} +@item @samp{id:B7423F4D-2E8A-471B-8810-C40F074717E9} +@tab link to heading by ID +@item @samp{news:comp.emacs} +@tab Usenet link +@item @samp{mailto:adent@@galaxy.net} +@tab mail link +@item @samp{mhe:folder#id} +@tab MH-E message link +@item @samp{rmail:folder#id} +@tab Rmail message link +@item @samp{gnus:group#id} +@tab Gnus article link +@item @samp{bbdb:R.*Stallman} +@tab BBDB link (with regexp) +@item @samp{irc:/irc.com/#emacs/bob} +@tab IRC link +@item @samp{info:org#Hyperlinks} +@tab Info node link +@end multitable + +File links can contain additional information to make Emacs jump to +a particular location in the file when following a link.

Because of its importance, we suggest to bind it +to a widely available key (see @ref{Activation}). It stores a link to the +current location. The link is stored for later insertion into an Org +buffer---see below. + +From an Org buffer, the following commands create, navigate or, more +generally, act on links. + +@table @asis +@item @kbd{C-c C-l} +Insert a link. This prompts for a link to be inserted into the +buffer. You can just type a link, or use history keys @kbd{@key{UP}} +and @kbd{@key{DOWN}} to access stored links. You will be prompted +for the description part of the link. + +When called with a @kbd{C-u} prefix argument, file name +completion is used to link to a file. + +@item @kbd{C-c C-l} (with point on existing link) +When point is on an existing link, @kbd{C-c C-l} allows you to +edit the link and description parts of the link. + +@item @kbd{C-c C-o} +Open link at point. + +@item @kbd{C-c &} +Jump back to a recorded position.

With Org mode, simply mark any +entry in a tree as being a TODO item.

See the docstring +of the option @code{org-todo-state-tags-triggers} for details. + +@node Multi-state Workflow +@section Multi-state Workflow + +You can use TODO keywords to indicate @@emph@{sequential@} working progress +states: + +@lisp +(setq org-todo-keywords + '((sequence "TODO" "FEEDBACK" "VERIFY" "|" "DONE" "DELEGATED"))) +@end lisp + +@noindent +The vertical bar separates the @samp{TODO} keywords (states that @emph{need +action}) from the @samp{DONE} states (which need @emph{no further action}). If +you do not provide the separator bar, the last state is used as the +@samp{DONE} state. With this setup, the command @kbd{C-c C-t} cycles +an entry from @samp{TODO} to @samp{FEEDBACK}, then to @samp{VERIFY}, and finally to +@samp{DONE} and @samp{DELEGATED}. + +Sometimes you may want to use different sets of TODO keywords in +parallel. For example, you may want to have the basic @samp{TODO=/=DONE}, +but also a workflow for bug fixing. Your setup would then look like +this: + +@lisp +(setq org-todo-keywords + '((sequence "TODO(t)" "|" "DONE(d)") + (sequence "REPORT(r)" "BUG(b)" "KNOWNCAUSE(k)" "|" "FIXED(f)"))) +@end lisp + +@noindent +The keywords should all be different, this helps Org mode to keep +track of which subsequence should be used for a given entry. The +example also shows how to define keys for fast access of a particular +state, by adding a letter in parenthesis after each keyword---you will +be prompted for the key after @kbd{C-c C-t}. + +To define TODO keywords that are valid only in a single file, use the +following text anywhere in the file. + +@example +#+TODO: TODO(t) | DONE(d) +#+TODO: REPORT(r) BUG(b) KNOWNCAUSE(k) | FIXED(f) +#+TODO: | CANCELED(c) +@end example + +After changing one of these lines, use @kbd{C-c C-c} with the +cursor still in the line to make the changes known to Org mode. + +@node Progress Logging +@section Progress Logging + +To record a timestamp and a note when changing a TODO state, call the +command @code{org-todo} with a prefix argument. + +@table @asis +@item @kbd{C-u C-c C-t} +Prompt for a note and record a the time of the TODO state change. +@end table + +Org mode can also automatically record a timestamp and optionally a +note when you mark a TODO item as DONE, or even each time you change +the state of a TODO item. This system is highly configurable, +settings can be on a per-keyword basis and can be localized to a file +or even a subtree. For information on how to clock working time for a +task, see @ref{Clocking Work Time}. + +@anchor{Closing items} +@subheading Closing items + +The most basic logging is to keep track of @emph{when} a certain TODO item +was marked as done. This can be achieved with@footnote{The corresponding in-buffer setting is @samp{#+STARTUP: logdone}.} + +@lisp +(setq org-log-done 'time) +@end lisp + +@noindent +Then each time you turn an entry from a TODO (not-done) state into any +of the DONE states, a line @samp{CLOSED: [timestamp]} is inserted just +after the headline. + +If you want to record a note along with the timestamp, use@footnote{The corresponding in-buffer setting is @samp{#+STARTUP: +logenotedone}.} + +@lisp +(setq org-log-done 'note) +@end lisp + +@noindent +You are then be prompted for a note, and that note is stored below the +entry with a @samp{Closing Note} heading. + +@anchor{Tracking TODO state changes} +@subheading Tracking TODO state changes + +You might want to keep track of TODO state changes. You can either +record just a timestamp, or a time-stamped note for a change. These +records are inserted after the headline as an itemized list. When +taking a lot of notes, you might want to get the notes out of the way +into a drawer. Customize the variable @code{org-log-into-drawer} to get +this behavior. + +For state logging, Org mode expects configuration on a per-keyword +basis. This is achieved by adding special markers @samp{!} (for +a timestamp) and @samp{@@} (for a note) in parentheses after each keyword. +For example: + +@example +#+TODO: TODO(t) WAIT(w@@/!) | DONE(d!) CANCELED(c@@) +@end example + + +@noindent +defines TODO keywords and fast access keys, and also request that +a time is recorded when the entry is set to @samp{DONE}, and that a note is +recorded when switching to @samp{WAIT} or @samp{CANCELED}. The same syntax +works also when setting @code{org-todo-keywords}. + +@node Priorities +@section Priorities + +If you use Org mode extensively, you may end up with enough TODO items +that it starts to make sense to prioritize them. Prioritizing can be +done by placing a @emph{priority cookie} into the headline of a TODO item, +like this + +@example +*** TODO [#A] Write letter to Sam Fortune +@end example + + +Org mode supports three priorities: @samp{A}, @samp{B}, and @samp{C}. @samp{A} is the +highest, @samp{B} the default if none is given. Priorities make +a difference only in the agenda. + +@table @asis +@item @kbd{C-c ,} +Set the priority of the current headline. Press @kbd{A}, +@kbd{B} or @kbd{C} to select a priority, or @kbd{@key{SPC}} +to remove the cookie. + +@item @kbd{S-@key{UP}} (@code{org-priority-up}) +@itemx @kbd{S-@key{DOWN}} (@code{org-priority-down}) +Increase/decrease the priority of the current headline. +@end table + +@node Breaking Down Tasks +@section Breaking Tasks Down into Subtasks + +It is often advisable to break down large tasks into smaller, +manageable subtasks. You can do this by creating an outline tree +below a TODO item, with detailed subtasks on the tree. To keep an +overview of the fraction of subtasks that have already been marked +as done, insert either @samp{[/]} or @samp{[%]} anywhere in the headline. These +cookies are updated each time the TODO status of a child changes, or +when pressing @kbd{C-c C-c} on the cookie. For example: + +@example +* Organize Party [33%] +** TODO Call people [1/2] +*** TODO Peter +*** DONE Sarah +** TODO Buy food +** DONE Talk to neighbor +@end example + +@node Checkboxes +@section Checkboxes + +Every item in a plain list (see @ref{Plain Lists}) can be made into +a checkbox by starting it with the string @samp{[ ]}. Checkboxes are not +included into the global TODO list, so they are often great to split +a task into a number of simple steps. + +Here is an example of a checkbox list. + +@example +* TODO Organize party [2/4] + - [-] call people [1/2] + - [ ] Peter + - [X] Sarah + - [X] order food +@end example + +Checkboxes work hierarchically, so if a checkbox item has children +that are checkboxes, toggling one of the children checkboxes makes the +parent checkbox reflect if none, some, or all of the children are +checked. + +The following commands work with checkboxes: + +@table @asis +@item @kbd{C-c C-c} +Toggle checkbox status or---with prefix argument---checkbox presence +at point. + +@item @kbd{M-S-@key{RET}} +Insert a new item with a checkbox. This works only if point is +already in a plain list item (see @ref{Plain Lists}). +@end table + +@node Tags +@chapter Tags + +An excellent way to implement labels and contexts for +cross-correlating information is to assign @emph{tags} to headlines. Org +mode has extensive support for tags. + +Every headline can contain a list of tags; they occur at the end of +the headline. Tags are normal words containing letters, numbers, @samp{_}, +and @samp{@@}. Tags must be preceded and followed by a single colon, e.g., +@samp{:work:}. Several tags can be specified, as in @samp{:work:urgent:}. Tags +by default are in bold face with the same color as the headline. + +@anchor{Tag inheritance} +@heading Tag inheritance + +Tags make use of the hierarchical structure of outline trees. If +a heading has a certain tag, all subheadings inherit the tag as well. +For example, in the list + +@example +* Meeting with the French group :work: +** Summary by Frank :boss:notes: +*** TODO Prepare slides for him :action: +@end example + +@noindent +the final heading has the tags @samp{work}, @samp{boss}, @samp{notes}, and @samp{action} +even though the final heading is not explicitly marked with those +tags. + +You can also set tags that all entries in a file should inherit just +as if these tags were defined in a hypothetical level zero that +surrounds the entire file. Use a line like this@footnote{As with all these in-buffer settings, pressing @kbd{C-c C-c} activates any changes in the line.}: + +@example +#+FILETAGS: :Peter:Boss:Secret: +@end example + +@anchor{Setting tags} +@heading Setting tags + +Tags can simply be typed into the buffer at the end of a headline. +After a colon, @kbd{M-@key{TAB}} offers completion on tags. There is +also a special command for inserting tags: + +@table @asis +@item @kbd{C-c C-q} +Enter new tags for the current headline. Org mode either offers +completion or a special single-key interface for setting tags, see +below. + +@item @kbd{C-c C-c} +When point is in a headline, this does the same as @kbd{C-c C-q}. +@end table + +Org supports tag insertion based on a @emph{list of tags}. By default this +list is constructed dynamically, containing all tags currently used in +the buffer. You may also globally specify a hard list of tags with +the variable @code{org-tag-alist}. Finally you can set the default tags +for a given file using the @samp{TAGS} keyword, like + +@example +#+TAGS: @@work @@home @@tennisclub +#+TAGS: laptop car pc sailboat +@end example + + +By default Org mode uses the standard minibuffer completion facilities +for entering tags. However, it also implements another, quicker, tag +selection method called @emph{fast tag selection}. This allows you to +select and deselect tags with just a single key press. For this to +work well you should assign unique letters to most of your commonly +used tags. You can do this globally by configuring the variable +@code{org-tag-alist} in your Emacs init file. For example, you may find +the need to tag many items in different files with @samp{@@home}. In this +case you can set something like: + +@lisp +(setq org-tag-alist '(("@@work" . ?w) ("@@home" . ?h) ("laptop" . ?l))) +@end lisp + +If the tag is only relevant to the file you are working on, then you +can instead set the @samp{TAGS} keyword as: + +@example +#+TAGS: @@work(w) @@home(h) @@tennisclub(t) laptop(l) pc(p) +@end example + +@anchor{Tag groups} +@heading Tag groups + +A tag can be defined as a @emph{group tag} for a set of other tags. The +group tag can be seen as the ``broader term'' for its set of tags. + +You can set group tags by using brackets and inserting a colon between +the group tag and its related tags: + +@example +#+TAGS: [ GTD : Control Persp ] +@end example + + +@noindent +or, if tags in the group should be mutually exclusive: + +@example +#+TAGS: @{ Context : @@Home @@Work @} +@end example + + +When you search for a group tag, it return matches for all members in +the group and its subgroups. In an agenda view, filtering by a group +tag displays or hide headlines tagged with at least one of the members +of the group or any of its subgroups. + +If you want to ignore group tags temporarily, toggle group tags +support with @code{org-toggle-tags-groups}, bound to @kbd{C-c C-x q}. + +@anchor{Tag searches} +@heading Tag searches + +@table @asis +@item @kbd{C-c / m} or @kbd{C-c \} +Create a sparse tree with all headlines matching a tags search. +With a @kbd{C-u} prefix argument, ignore headlines that are not +a TODO line. + +@item @kbd{M-x org-agenda m} +Create a global list of tag matches from all agenda files.

The full syntax of +the search string is rich and allows also matching against TODO +keywords, entry levels and properties. For a more detailed description +with many examples, see @ref{Matching Tags and Properties}. + +@node Properties +@chapter Properties + +Properties are key-value pairs associated with an entry. They live in +a special drawer with the name @samp{PROPERTIES}. Each property is +specified on a single line, with the key (surrounded by colons) first, +and the value after it: + +@example +* CD collection +** Classic +*** Goldberg Variations + :PROPERTIES: + :Title: Goldberg Variations + :Composer: J.S. Bach + :Publisher: Deutsche Grammophon + :NDisks: 1 + :END: +@end example + +You may define the allowed values for a particular property @samp{Xyz} by +setting a property @samp{Xyz_ALL}. This special property is @emph{inherited}, +so if you set it in a level 1 entry, it applies to the entire tree. +When allowed values are defined, setting the corresponding property +becomes easier and is less prone to typing errors. For the example +with the CD collection, we can pre-define publishers and the number of +disks in a box like this: + +@example +* CD collection + :PROPERTIES: + :NDisks_ALL: 1 2 3 4 + :Publisher_ALL: "Deutsche Grammophon" Philips EMI + :END: +@end example + +If you want to set properties that can be inherited by any entry in +a file, use a line like: + +@example +#+PROPERTY: NDisks_ALL 1 2 3 4 +@end example + + +The following commands help to work with properties: + +@table @asis +@item @kbd{C-c C-x p} +Set a property. This prompts for a property name and a value. + +@item @kbd{C-c C-c d} +Remove a property from the current entry. +@end table + +To create sparse trees and special lists with selection based on +properties, the same commands are used as for tag searches (see +@ref{Tags}). The syntax for the search string is described in @ref{Matching Tags and Properties}. + +@node Dates and Times +@chapter Dates and Times + +To assist project planning, TODO items can be labeled with a date +and/or a time. The specially formatted string carrying the date and +time information is called a @emph{timestamp} in Org mode. + +@menu +* Timestamps:: Assigning a time to a tree entry. +* Creating Timestamps:: Commands that insert timestamps. +* Deadlines and Scheduling:: Planning your work. +* Clocking Work Time:: Tracking how long you spent on a task. +@end menu + +@node Timestamps +@section Timestamps + +A timestamp is a specification of a date---possibly with a time or +a range of times---in a special format, either @samp{<2003-09-16 Tue>} or +@samp{<2003-09-16 Tue 09:39>} or @samp{<2003-09-16 Tue 12:00-12:30>}. +A timestamp can appear anywhere in the headline or body of an Org tree +entry.

All commands listed below produce timestamps in the correct +format. + +@table @asis +@item @kbd{C-c .} +Prompt for a date and insert a corresponding timestamp. When point +is at an existing timestamp in the buffer, the command is used to +modify this timestamp instead of inserting a new one. When this +command is used twice in succession, a time range is inserted. With +a prefix argument, it also adds the current time. + +@item @kbd{C-c !} +Like @kbd{C-c .}, but insert an inactive timestamp that does +not cause an agenda entry. + +@item @kbd{S-@key{LEFT}} +@itemx @kbd{S-@key{RIGHT}} +Change date at point by one day. + +@item @kbd{S-@key{UP}} +@itemx @kbd{S-@key{DOWN}} +On the beginning or enclosing bracket of a timestamp, change its +type. Within a timestamp, change the item under point. Point can +be on a year, month, day, hour or minute. When the timestamp +contains a time range like @samp{15:30-16:30}, modifying the first time +also shifts the second, shifting the time block with constant +length. To change the length, modify the second time. +@end table + + +When Org mode prompts for a date/time, it accepts any string +containing some date and/or time information, and intelligently +interprets the string, deriving defaults for unspecified information +from the current date and time. You can also select a date in the +pop-up calendar. See the manual for more information on how exactly +the date/time prompt works. + +@node Deadlines and Scheduling +@section Deadlines and Scheduling + +A timestamp may be preceded by special keywords to facilitate +planning: + +@table @asis +@item @kbd{C-c C-d} +Insert @samp{DEADLINE} keyword along with a time stamp, in the line +following the headline. + +Meaning: the task---most likely a TODO item, though not +necessarily---is supposed to be finished on that date. + +On the deadline date, the task is listed in the agenda. In +addition, the agenda for @emph{today} carries a warning about the +approaching or missed deadline, starting @code{org-deadline-warning-days} +before the due date, and continuing until the entry is marked as +done. An example: + +@example +*** TODO write article about the Earth for the Guide + DEADLINE: <2004-02-29 Sun> + The editor in charge is [[bbdb:Ford Prefect]] +@end example + +@item @kbd{C-c C-s} +Insert @samp{SCHEDULED} keyword along with a stamp, in the line following +the headline. + +Meaning: you are planning to start working on that task on the given +date@footnote{This is quite different from what is normally understood by +@emph{scheduling a meeting}, which is done in Org by just inserting a time +stamp without keyword.}. + +The headline is listed under the given date@footnote{It will still be listed on that date after it has been marked +as done. If you do not like this, set the variable +@code{org-agenda-skip-scheduled-if-done}.}. In addition, +a reminder that the scheduled date has passed is present in the +compilation for @emph{today}, until the entry is marked as done, i.e., +the task is automatically forwarded until completed. + +@example +*** TODO Call Trillian for a date on New Years Eve. + SCHEDULED: <2004-12-25 Sat> +@end example +@end table + +Some tasks need to be repeated again and again.

Use @kbd{C-c '} again to close the buffer +and return to the Org buffer. + +@anchor{Using header arguments} +@heading Using header arguments + +A header argument is specified with an initial colon followed by the +argument's name in lowercase. + +Header arguments can be set in several ways; Org prioritizes them in +case of overlaps or conflicts by giving local settings a higher +priority. + +@table @asis +@item System-wide header arguments +Those are specified by customizing @code{org-babel-default-header-args} +variable, or, for a specific language @var{LANG} +@code{org-babel-default-header-args:LANG}. + +@item Header arguments in properties +You can set them using @samp{header-args} property (see @ref{Properties})---or +@samp{header-args:LANG} for language @var{LANG}. Header arguments +set through properties drawers apply at the sub-tree level on down. + +@item Header arguments in code blocks +Header arguments are most commonly set at the source code block +level, on the @samp{BEGIN_SRC} line: + +@example +#+NAME: factorial +#+BEGIN_SRC haskell :results silent :exports code :var n=0 + fac 0 = 1 + fac n = n * fac (n-1) +#+END_SRC +@end example + +Code block header arguments can span multiple lines using @samp{HEADER} +keyword on each line. +@end table + +@anchor{Evaluating code blocks} +@heading Evaluating code blocks + +Use @kbd{C-c C-c} to evaluate the current code block and insert +its results in the Org document. By default, evaluation is only +turned on for @samp{emacs-lisp} code blocks, however support exists for +evaluating blocks in many languages. For a complete list of supported +languages see the manual. The following shows a code block and its +results. + +@example +#+BEGIN_SRC emacs-lisp + (+ 1 2 3 4) +#+END_SRC + +#+RESULTS: +: 10 +@end example + +The following syntax is used to pass arguments to code blocks using +the @samp{var} header argument. + +@example +:var NAME=ASSIGN +@end example + + +@noindent +@var{NAME} is the name of the variable bound in the code block +body. @var{ASSIGN} is a literal value, such as a string, +a number, a reference to a table, a list, a literal example, another +code block---with or without arguments---or the results of evaluating +a code block. + +@anchor{Results of evaluation} +@heading Results of evaluation + +How Org handles results of a code block execution depends on many +header arguments working together. The primary determinant, however, +is the @samp{results} header argument. It controls the @emph{collection}, +@emph{type}, @emph{format}, and @emph{handling} of code block results. + +@table @asis +@item Collection +How the results should be collected from the code block. You may +choose either @samp{output} or @samp{value} (the default). + +@item Type +What result types to expect from the execution of the code block. +You may choose among @samp{table}, @samp{list}, @samp{scalar}, and @samp{file}. Org +tries to guess it if you do not provide it. + +@item Format +How Org processes results. Some possible values are @samp{code}, +@samp{drawer}, @samp{html}, @samp{latex}, @samp{link}, and @samp{raw}. + +@item Handling +How to insert the results once properly formatted. Allowed values +are @samp{silent}, @samp{replace} (the default), @samp{append}, or @samp{prepend}. +@end table + +Code blocks which output results to files---e.g.: graphs, diagrams and +figures---can accept a @samp{:file FILENAME} header argument, in which case +the results are saved to the named file, and a link to the file is +inserted into the buffer. + +@anchor{Exporting code blocks} +@heading Exporting code blocks + +It is possible to export the @emph{code} of code blocks, the @emph{results} of +code block evaluation, @emph{both} the code and the results of code block +evaluation, or @emph{none}. Org defaults to exporting @emph{code} for most +languages. + +The @samp{exports} header argument is to specify if that part of the Org +file is exported to, say, HTML or @LaTeX{} formats. It can be set to +either @samp{code}, @samp{results}, @samp{both} or @samp{none}. + +@anchor{Extracting source code} +@heading Extracting source code + +Use @kbd{C-c C-v t} to create pure source code files by +extracting code from source blocks in the current buffer. This is +referred to as ``tangling''---a term adopted from the literate +programming community. During tangling of code blocks their bodies +are expanded using @code{org-babel-expand-src-block}, which can expand both +variable and ``Noweb'' style references. In order to tangle a code +block it must have a @samp{tangle} header argument, see the manual for +details. + +@node Miscellaneous +@chapter Miscellaneous + + + +@anchor{Completion} +@heading Completion + +Org has in-buffer completions with @kbd{M-@key{TAB}}. No minibuffer is +involved. Type one or more letters and invoke the hot key to complete +the text in-place. + +For example, this command will complete @TeX{} symbols after @samp{\}, TODO +keywords at the beginning of a headline, and tags after @samp{:} in +a headline. + +@anchor{Structure Templates} +@heading Structure Templates + +To quickly insert empty structural blocks, such as @samp{#+BEGIN_SRC} +@dots{} @samp{#+END_SRC}, or to wrap existing text in such a block, use + +@table @asis +@item @kbd{C-c C-,} +Prompt for a type of block structure, and insert the block at point. +If the region is active, it is wrapped in the block. +@end table + +@anchor{Clean view} +@heading Clean view + +Org's default outline with stars and no indents can become too +cluttered for short documents. For @emph{book-like} long documents, the +effect is not as noticeable. Org provides an alternate stars and +indentation scheme, as shown on the right in the following table. It +uses only one star and indents text to line with the heading: + +@example +* Top level headline | * Top level headline +** Second level | * Second level +*** Third level | * Third level + some text | some text +*** Third level | * Third level + more text | more text +* Another top level headline | * Another top level headline +@end example + +This kind of view can be achieved dynamically at display time using +Org Indent mode (@kbd{M-x org-indent-mode @key{RET}}), which prepends +intangible space to each line. You can turn on Org Indent mode for +all files by customizing the variable @code{org-startup-indented}, or you +can turn it on for individual files using + +@example +#+STARTUP: indent +@end example + + +If you want the indentation to be hard space characters so that the +plain text file looks as similar as possible to the Emacs display, Org +supports you by helping to indent (with @kbd{@key{TAB}}) text below +each headline, by hiding leading stars, and by only using levels 1, 3, +etc to get two characters indentation for each level. To get this +support in a file, use + +@example +#+STARTUP: hidestars odd +@end example + +@bye \ No newline at end of file diff --git a/elpa/org-9.5.2/doc/pdflayout.sty b/elpa/org-9.5.2/doc/pdflayout.sty new file mode 100644 index 0000000..7fb6afd --- /dev/null +++ b/elpa/org-9.5.2/doc/pdflayout.sty @@ -0,0 +1,44 @@ +% Copyright (C) 2007-2013 Free Software Foundation, Inc. + +% This file is part of GNU Emacs. + +% GNU Emacs is free software: you can redistribute it and/or modify +% it under the terms of the GNU General Public License as published by +% the Free Software Foundation, either version 3 of the License, or +% (at your option) any later version. + +% GNU Emacs is distributed in the hope that it will be useful, +% but WITHOUT ANY WARRANTY; without even the implied warranty of +% MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The Org mode LaTeX exporter is now able to process and +export arbitrary float types. The user is responsible for ensuring +that Org mode configures LaTeX to process any new float type. + +*** Support verse and quote blocks in LaTeX export + +The LaTeX export back-end accepts four attributes for verse blocks: +=:lines=, =:center=, =:versewidth= and =:latexcode=. The three first +require the external LaTeX package =verse.sty=, which is an extension +of the standard LaTeX environment. + +The LaTeX export back-end accepts two attributes for quote blocks: +=:environment=, for an arbitrary quoting environment (the default +value is that of =org-latex-default-quote-environment=: ="quote"=) and +=:options=. + +*** =org-set-tags-command= selects tags from ~org-global-tags-completion-table~ + +Let ~org-set-tags-command~ TAB fast tag completion interface complete +tags including from both buffer local and user defined persistent +global list (~org-tag-alist~ and ~org-tag-persistent-alist~). Now +option ~org-complete-tags-always-offer-all-agenda-tags~ is honored. + +*** Clocktable option =:formula %= now shows the per-file time percentages + +This change only has an effect when multiple files are contributing to +a given clocktable (such as when =:scope agenda= has been specified). +The existing behavior is that such tables have an extra 'File' column, +and each individual file that contributes has its own summary line +with the headline value '*File time*'. Those summary rows also +produce a rollup time value for the file in the 'Time' column. + +Prior to this change, the built-in =%= formula did not produce a +calculation for those per-file times in the '%' column (the relevant +cells in the '%' column were blank). With this change, the percentage +contribution of each individual file time to the total time is shown. + +The more agenda files you have, the more useful this behavior becomes. + +*** =ob-python.el= improvements to =:return= header argument + +The =:return= header argument in =ob-python= now works for session +blocks as well as non-session blocks. Also, it now works with the +=:epilogue= header argument -- previously, setting the =:return= +header would cause the =:epilogue= to be ignored. + +This change allows more easily moving boilerplate out of the main code +block and into the header. For example, for plotting, we need to add +boilerplate to save the figure to a file and return the +filename. Instead of doing this within the code block, we can now +handle it through the header arguments as follows: + +#+BEGIN_SRC org +,#+header: :var fname="/home/jack/tmp/plot.svg" +,#+header: :epilogue plt.savefig(fname) +,#+header: :return fname +,#+begin_src python :results value file + import matplotlib, numpy + import matplotlib.pyplot as plt + fig=plt.figure(figsize=(4,2)) + x=numpy.linspace(-15,15) + plt.plot(numpy.sin(x)/x) + fig.tight_layout() +,#+end_src + +,#+RESULTS: +[[file:/home/jack/tmp/plot.svg]] +#+END_SRC + +As another example, we can use =:return= with the external [[https://pypi.org/project/tabulate/][tabulate]] +package, to convert pandas Dataframes into orgmode tables: + +#+begin_src org +,#+header: :prologue from tabulate import tabulate +,#+header: :return tabulate(table, headers=table.columns, tablefmt="orgtbl") +,#+begin_src python :results value raw :session + import pandas as pd + table = pd.DataFrame({ + "a": [1,2,3], + "b": [4,5,6] + }) +,#+end_src + +,#+RESULTS: +| | a | b | +|---+---+---| +| 0 | 1 | 4 | +| 1 | 2 | 5 | +| 2 | 3 | 6 | +#+end_src + +*** Display images with width proportional to the buffer text width + +Previously, if you used a =:width= attribute like =#+attr_html: :width 70%= or +=#+attr_latex: :width 0.7\linewidth= this would be interpreted as a 70px wide and +0.7px wide width specification respectively. + +Now, percentages are transformed into floats (i.e. 70% becomes 0.7), +and float width specifications between 0.0 and 2.0 are now interpreted +as that portion of the text width in the buffer. For instance, the +above examples of =70%= and =0.7\linewidth= will result in an image +with width equal to the pixel-width of the buffer text multiplied by 0.7. + +This functionality is implemented in a new function, +~org-display-inline-image--width~ which contains the width +determination logic previously in ~org-display-inline-images~ and the +new behaviour. + +** New options +*** Option ~org-hidden-keywords~ now also applies to #+SUBTITLE: + +The option ~org-hidden-keywords~ previously applied +to #+TITLE:, #+AUTHOR:, #+DATE:, and #+EMAIL:. Now it can also be +used to hide the #+SUBTITLE: keyword. + +*** New formatting directive ~%L~ for org-capture + +The new ~%L~ formatting directive contains the bare link target, and +may be used to create links with programmatically generated +descriptions. + +*** New option ~org-id-ts-format~ + +Earlier, IDs generated using =ts= method had a hard-coded format (i.e. =20200923T160237.891616=). +The new option allows user to customise the format. +Defaults are unchanged. + +*** New argument for ~file-desc~ babel header + +It is now possible to provide the =file-desc= header argument for a +babel source block but omit the description by passing an empty vector +as an argument (i.e., :file-desc []). This can be useful because +providing =file-desc= without an argument results in the result of +=file= being used in the description. Previously, the only way to +omit a file description was to omit the header argument entirely, +which made it difficult/impossible to provide a default value for +=file-desc=. + +*** New option to set ~org-link-file-path-type~ to a function + +~org-link-file-path-type~ can now be set to a function that takes the +full filename as an argument and returns the path to link to. + +For example, if you use ~project.el~, you can set this function to use +relative links within a project as follows: + +#+begin_src emacs-lisp +(setq (org-link-file-path-type + (lambda (path) + (let* ((proj (project-current)) + (root (if proj (project-root proj) default-directory))) + (if (string-prefix-p (expand-file-name root) path) + (file-relative-name path) + (abbreviate-file-name path)))))) +#+end_src + +*** New options and new behavior for babel LaTeX SVG image files + +Org babel now uses a two-stage process for converting latex source +blocks to SVG image files (when the extension of the output file is +~.svg~). The first stage in the process converts the latex block into +a PDF file, which is then converted into an SVG file in the second +stage. The TeX->PDF part uses the existing infrastructure for +~org-babel-latex-tex-to-pdf~. The PDF->SVG part uses a command +specified in a new customization, +~org-babel-latex-pdf-svg-process~. By default, this uses inkscape for +conversion, but since it is fully customizable, any other command can +be used in its place. For instance, dvisvgm might be used here. This +two-part processing replaces the previous use of htlatex to process +LaTeX directly to SVG (htlatex is still used for HTML conversion). + +Conversion to SVG exposes a number of additional customizations that +give the user full control over the contents of the latex source +block. ~org-babel-latex-preamble~, ~org-babel-latex-begin-env~ and +~org-babel-latex-end-env~ are new customization options added to allow +the user to specify the preamble and code that preceedes and proceeds +the contents of the source block. + +*** New option ~org-html-meta-tags~ allows for HTML meta tags customization + +New variable ~org-html-meta-tags~ makes it possible to customize the +== tags used in an HTML export. Accepts either a static list of +values, or a function that generates such a list (see +~org-html-meta-tags-default~ as an example of the latter). + +*** Option ~org-agenda-bulk-custom-functions~ now supports collecting bulk arguments + +When specifying a custom agenda bulk option, you can now also specify +a function which collects the arguments to be used with each call to +the custom function. + +*** New faces to improve the contextuality of Org agenda views + +Four new faces improve certain styles and offer more flexibility for +some Org agenda views: ~org-agenda-date-weekend-today~, +~org-imminent-deadline~, ~org-agenda-structure-secondary~, +~org-agenda-structure-filter~. They inherit from existing faces in +order to remain backward-compatible. + +Quoting from [[https://list.orgmode.org/87lf7q7gpq.fsf@protesilaos.com/][this thread]]: + +#+begin_quote ++ The 'org-imminent-deadline' is useful to disambiguate generic + warnings from deadlines. For example, a warning could be rendered + in a yellow colored text and have a bold weight, whereas a deadline + might be red and styled with italics. + ++ The 'org-agenda-structure-filter' applies to all tag/term filters + in agenda views that search for keywords or patterns. It is + designed to inherit from 'org-agenda-structure' in addition to the + 'org-warning' face that was present before (and removes the + generic 'warning' face from one place). This offers the benefit + of consistency, as, say, an increase in font height or a change in + font family in 'org-agenda-structure' will propagate to the filter + as well. The whole header line thus looks part of a singular + design. + ++ The 'org-agenda-structure-secondary' complements the above for those + same views where a description follows the header. For instance, the + tags view provides information to "Press N r" to filter by a + numbered tag. Themes/users may prefer to disambiguate this line + from the header above it, such as by using a less intense color or by + reducing its height relative to the 'org-agenda-structure'. + ++ The 'org-agenda-date-weekend-today' provides the option to + differentiate the current date on a weekend from the current date on + weekdays. +#+end_quote + +*** New option ~org-clock-ask-before-exiting~ + +By default, a function is now added to ~kill-emacs-query-functions~ +that asks whether to clock out and save when there's a running clock. +Customize ~org-clock-ask-before-exiting~~ to nil to disable this new +behavior. + +*** Option ~org-html-inline-image-rules~ now includes .webp + +By default ox-html now inlines webp images. + +*** ~org-html-head-include-scripts~ is now =nil= by default + +See [[msg:498dbe2e-0cd2-c81e-7960-4a26c566a1f7@memebeam.org][this thread]]. + +*** New option ~org-html-content-class~ + +This is the CSS class name to use for the top level content wrapper. + +*** New option ~org-babel-plantuml-svg-text-to-path~ + +This option, nil by default, allows to add a SVG-specific post-export +step that runs inkscape text-to-path replacement over the output file. + +*** You can now configure ~org-html-scripts~ and ~org-html-style-default~ + +~org-html-scripts~ and ~org-html-style-default~ used to be constants, +you can now configure them. + +*** New option ~org-attach-git-dir~ + +~org-attach-git-dir~ will decide whether to use ~org-attach-git-dir~ +(the default) or use the attachment directory of the current node, if +it is correctly configured as a Git repository. + +*** Some faces now use fixed-pitch + +See [[msg:875z8njaol.fsf@protesilaos.com][this thread]]. + +*** New option ~org-attach-sync-delete-empty-dir~ + +~org-attach-sync-delete-empty-dir~ controls the deletion of an empty +attachment directory at calls of ~org-attach-sync~.

Previously, only direct strings were +supported. These closures are evaluated when point is at the source +block, which allows them to make use of contextual information at the +relevant source block. One example that illustrates the usefulness of +this addition (also given in the documentation for +~org-babel-default-header-args~) is: + +#+begin_src elisp +(defun org-src-sha () + (let ((elem (org-element-at-point))) + (concat (sha1 (org-element-property :value elem)) \".svg\"))) + +(setq org-babel-default-header-args:latex + `((:results . \"file link replace\") + (:file . (lambda () (org-src-sha))))) +#+end_src + +This will set the ~:file~ header argument to the sha1 checksum of the +contents of the current latex source block. + +Finally, the closures are only evaluated if they're not overridden for +a source block. This improves efficiency in cases where the result of +a compute-expensive closure would otherwise be discarded. + +** Miscellaneous +*** =org-bibtex= includes =doi= and =url= entries when exporting to BiBTeX +=doi= and =url= entries have been made optional for some publication +types and will be exported if present for those types. +*** Missing or empty placeholders in "eval" macros are now =nil= +They used to be the empty string. +*** =org-goto-first-child= now works before first heading + +When point is before first heading =org-goto-first-child= will move +point to the first child heading, or return nil if no heading exist +in buffer.

Since +every other backend was already using xcolor to set fg and bg, the CLI +alternative was removed and there is no more a :use-xcolor options +since now it's implicitly always true. + +*** Org-Attach Git commit + +[[*Org-Attach has been refactored and extended][Refactoring of Org-Attach]] affected the Git commit functionality.

Instead + one need to require the =org-attach-git= module in the startup. + +** New features +*** New option to wrap source code lines in HTML export + +When new option ~html-wrap-src-lines~ (with variable +~org-html-wrap-src-lines~) is non-nil, HTML export wraps source code +lines in HTML ~code~ elements. + +*** New option to handle schedules and deadlines in iCalendar export + +Export ignore done tasks with a deadline when +~org-icalendar-use-deadline~ contains ~event-if-todo-not-done~. +Likewise, scheduled done tasks are also ignored when +~org-icalendar-use-scheduled~ contains the same symbol. + +*** Add ~split-window-right~ option for src block edit window placement + +Given the increasing popularity of wide screen monitors, splitting +horizontally may make more sense than splitting vertically. An +option, ~split-window-right~, to request horizontal splitting has been +added to ~org-src-window-setup~. + +*** Org-Attach has been refactored and extended + +Org attach has been refactored and the functionality extended. It +should now be easier to understand how it works. A few improvements +and extra options have been added as well. + +From the initial comment in org-attach source-code: + +- Attachments are managed either by using a custom property DIR or by + using property ID from org-id. When DIR is defined, a location in + the filesystem is directly attached to the outline node. When + org-id is used, attachments are stored in a folder named after the + ID, in a location defined by ~org-attach-id-dir~. DIR has + precedence over ID when both parameters are defined for the current + outline node (also when inherited parameters are taken into + account). + +From now on inheritance requires no extra property and will adhere to +~org-attach-use-inheritance~ by default. Inheritance can be +customized to always be activated or never be activated in +~org-attach-use-inheritance~. + +The ATTACH_DIR property is deprecated in favor of the shorter +property DIR. Links to folders inside the DIR property can now be +declared as relative links. This is not enabled by default, but can +be set in ~org-attach-dir-relative~. + +When adding new attachment to the outline node the preferred way of +doing so can be customized. Take a look at +~org-attach-preferred-new-method~. It defaults to using ID since that +was the behavior before this change. + +If both DIR and ID properties are set on the same node, DIR has +precedence and will be used. + +One can now also choose to build attachment-directory-paths in a +customized way. This is an advanced topic, but in some case it makes +sense to parse an ID in a different way than the default one. Create +your own function and add it to the beginning of +~org-attach-id-to-path-function~list~ if you want to customize the ID +based folder structure. + +If you've used ATTACH_DIR properties to manage attachments, use the +following code to rename that property to DIR which supports the same +functionality. ATTACH_DIR_INHERIT is no longer supported and is +removed. + +#+begin_src emacs-lisp + (defun org-update-attach-properties () + "Change properties for Org-Attach." + (interactive) + (org-with-point-at 1 + (while (outline-next-heading) + (let ((DIR (org--property-local-values "ATTACH_DIR" nil))) + (when DIR + (org-set-property "DIR" (car DIR)) + (org-delete-property "ATTACH_DIR")))) + (org-delete-property-globally "ATTACH_DIR_INHERIT"))) +#+end_src + +For those who hate breaking changes, even though the changes are made +to clean things up; fear not. ATTACH_DIR will still continue to work. +It's just not documented any longer. When you get the chance, run the +code above to clean things up anyway! + +**** New hooks +Two hooks are added to org-attach: +- org-attach-after-change-hook +- org-attach-open-hook + +They are added mostly for internal restructuring purposes, but can +ofc. be used for other things as well. + +*** New link-type: Attachment + +Attachment-links are now first-class citizens. They mimic file-links +in everything they do but use the existing attachment-folder as a base +when expanding the links. Both =DIR= and =ID= properties are used to +try to resolve the links, in exactly the same way as Org-Attach uses +those properties. + +*** Handle overlay specification for notes in Beamer export + +This aligns Beamer notes with slide overlays. + +*** Add support for lettered lists in Texinfo + +Using =:enum A= or =:enum a= Texinfo attribute switches an otherwise +numbered list to a lettered list. + +*** Add a dispatcher command to insert dynamic blocks + +You can add new dynamic blocks with function +~org-dynamic-block-define~. All such dynamic blocks can be used by +~org-dynamic-block-insert-dblock~ command. + +*** Babel + +**** ob-emacs-lisp sets ~lexical-binding~ in Org edit buffers + +When editing an Elisp src block, the editing buffer's +~lexical-binding~ is set according to the src block's =:lexical= +parameter. + +**** Add LaTeX output support in PlantUML + +*** New minor mode to display headline numbering + +Use == to get a visual indication of the numbering +in the outline. The numbering is also automatically updated upon +changes in the buffer. + +*** New property =HTML_HEADLINE_CLASS= in HTML export + +The new property =HTML_HEADLINE_CLASS= assigns a class attribute to +a headline. + +*** Allow LaTeX attributes and captions for "table.el" tables + +Supported LaTeX attributes are ~:float~, ~:center~, ~:font~ and +~:caption~. + +*** Attach buffer contents to headline + +With == key from attachment dispatcher (==), it is now +possible to write the contents of a buffer to a file in the headline +attachment directory. + +*** iCalendar export respects a =CLASS= property + +Set the =CLASS= property on an entry to specify a visibility class for +that entry only during iCalendar export. The property can be set to +anything the calendar server supports. The iCalendar standard defines +the values =PUBLIC=, =CONFIDENTIAL=, =PRIVATE=, which can be +interpreted as publicly visible, accessible to a specific group, and +private respectively. + +This property can be inherited during iCalendar export, depending on +the value of ~org-use-property-inheritance~. + +*** New parameter for =INCLUDE= keyword + +Add =:coding CODING-SYSTEM= to include files using a different coding +system than the main Org document. For example: + +#+begin_example +,#+INCLUDE: "myfile.cmd" src cmd :coding cp850-dos +#+end_example + +*** New values in clock tables' step: =month= and =year= +*** ODT export handles numbers cookies in lists +*** New cell movement functions in tables + +~S-~, ~S-~, ~S-~, and ~S-~ now move cells in +the corresponding direction by swapping with the adjacent cell. + +*** New option to natively fontify LaTeX snippets and environments + +A 'native option was added to org-highlight-latex-and-related. It +matches the same structures than 'latex but it calls +org-src-font-lock-fontify-block instead, thus bringing about full +LaTeX font locking. + +*** ~org-clone-subtree-with-time-shift~ learned to shift backward in time + +== (~org-clone-subtree-with-time-shift~) now takes a +negative value as a valid repeater to shift time stamps in backward +in cloned subtrees. You can give, for example, ‘-3d’ to shift three +days in the past. + +*** Toggle display of all vs. undone scheduled habits conveniently + +== (~org-habit-toggle-display-in-agenda~) in an agenda toggles +the display of all habits to those which are undone and scheduled. +This is a function for convenience. + +*** New parameter for SQL Babel blocks: ~:dbconnection~ + +The new parameter ~:dbconnection~ allows to specify a connection name +in a SQL block header: this name is used to look up connection +parameters in ~sql-connection-alist~. + +*** New =:scale= attribute supported by LaTeX exporters + +The builtin "latex" exporters now accept and use a =:scale= attribute, +which scales an image by a given factor. + +This attribute is wrapped around the =scale= parameter of LaTeX's +=\includegraphics= (bitmap images) or a TiKZ's =\scalebox=. +Therefore, its value should be some string palatable to LaTeX as +a positive float Its default value is an empty string (i.e. disabled). + +This attribute overrides the =:width= and =:height= attributes. + +#+begin_example +,#+name: Beastie +,#+caption: I think I saw this curious horse already, but where ? +,#+LATEX_ATTR: :scale 2 +[[https://orgmode.org/img/org-mode-unicorn-logo.png]] +#+end_example + +*** Allow specifying the target for a table of contents + +The =+TOC= keyword now accepts a =:target:= attribute that specifies +the headline to use for making the table of contents. + +#+begin_example +,* Target + :PROPERTIES: + :CUSTOM_ID: TargetSection + :END: +,** Heading A +,** Heading B +,* Another section +,#+TOC: headlines 1 :target "#TargetSection" +#+end_example +** New functions +*** ~org-dynamic-block-insert-dblock~ + +Use default keybinding == to run command +~org-dynamic-block-insert-dblock~.

By +default, the CSS styling of class ~org-svg~ specifies an image width of +90\thinsp{}% of the container the image. + +**** Markdown footnote export customization + +Variables ~org-md-footnotes-section~ and ~org-md-footnote-format~ +introduced for =ox-md.el=. Both new variables define template strings +which can be used to customize the format of the exported footnotes +section and individual footnotes, respectively. + +*** Babel + +**** Blocks with coderefs labels can now be evaluated + +The labels are removed prior to evaluating the block. + +**** Support for Lua language +**** Support for SLY in Lisp blocks + +See ~org-babel-lisp-eval-fn~ to activate it. + +**** Support for Stan language + +New ob-stan.el library. + +Evaluating a Stan block can produce two different results. + +1. Dump the source code contents to a file. + + This file can then be used as a variable in other blocks, which + allows interfaces like RStan to use the model. + +2. Compile the contents to a model file. + + This provides access to the CmdStan interface.

Thus, they can be used to generate to be published +Org files. + +*** Function ~org-remove-indentation~ changes. + +The new algorithm doesn't remove TAB characters not used for +indentation. + +*** Secure placeholders in capture templates + +Placeholders in capture templates are no longer expanded recursively. +However, ~%(...)~ constructs are expanded very late, so you can fill +the contents of the S-exp with the replacement text of non-interactive +placeholders. As before, interactive ones are still expanded as the +very last step, so the previous statement doesn't apply to them. + +Note that only ~%(...)~ placeholders initially present in the +template, or introduced using a file placeholder, i.e., ~%[...]~ are +expanded. This prevents evaluating potentially malicious code when +another placeholder, e.g., ~%i~ expands to a S-exp. + +*** Links stored by ~org-gnus-store-link~ in nnir groups + +Since gnus nnir groups are temporary, ~org-gnus-store-link~ now refers +to the article's original group. + +*** ~org-babel-check-confirm-evaluate~ is now a function instead of a macro + +The calling convention has changed. + +*** HTML export table row customization changes + +Variable ~org-html-table-row-tags~ has been split into +~org-html-table-row-open-tag~ and ~org-html-table-row-close-tag~. +Both new variables can be either a string or a function which will be +called with 6 parameters. + +*** =ITEM= special property returns headline without stars +*** Rename ~org-insert-columns-dblock~ into ~org-columns-insert-dblock~ + +The previous name is, for the time being, kept as an obsolete alias. + +*** ~org-trim~ can preserve leading indentation. + +When setting a new optional argument to a non-nil value, ~org-trim~ +preserves leading indentation while removing blank lines at the +beginning of the string. The behavior is identical for white space at +the end of the string. + +*** Function ~org-info-export~ changes. + +HTML links created from certain info links now point to =gnu.org= URL's rather +than just to local files. For example info links such as =info:emacs#List +Buffers= used to be converted to HTML links like this: + +: emacs#List Buffers + +where local file =emacs.html= is referenced. +For most folks this file does not exist. +Thus the new behavior is to generate this HTML link instead: + +: emacs#List Buffers + +All emacs related info links are similarly translated plus few other +=gnu.org= manuals. + +*** Repeaters with a ~++~ interval and a time can be shifted to later today + +Previously, if a recurring task had a timestamp of +~<2016-01-01 Fri 20:00 ++1d>~ and was completed on =2016-01-02= at +=08:00=, the task would skip =2016-01-02= and would be rescheduled for +=2016-01-03=.

That term is now changed to "Tag hierarchy". + +The following in-buffer definition: + +#+BEGIN_SRC org + ,#+TAGS: [ Group : SubOne SubTwo ] + ,#+TAGS: [ SubOne : SubOne1 SubOne2 ] + ,#+TAGS: [ SubTwo : SubTwo1 SubTwo2 ] +#+END_SRC + +Should be seen as the following tree of tags: + +- Group + - SubOne + - SubOne1 + - SubOne2 + - SubTwo + - SubTwo1 + - SubTwo2 + +Searching for "Group" should return all tags defined above.

This syntax is +already used for exclusive tags and Grouptags need their own, +non-exclusive syntax. This behavior is achieved with [ ]. Note: { } +can still be used also for Grouptags but then only one of the given +tags can be used on the headline at the same time. Example: + +[ group : sub1 sub2 ] + +#+BEGIN_SRC org +,* Test :sub1:sub2: +#+END_SRC + +This is a more general case than the already existing syntax for +grouptags; { }. + +*** Define regular expression patterns as tags + +Tags can be defined as grouptags with regular expressions as +"sub-tags". + +The regular expressions in the group must be marked up within { }. +Example use: + +: #+TAGS: [ Project : {P@.+} ] + +Searching for the tag Project will now list all tags also including +regular expression matches for P@.+. This is good for example for +projects tagged with a common identifier, i.e. P@2014_OrgTags. + +*** Filtering in the agenda on grouptags (Tag hierarchies) + +Filtering in the agenda on grouptags filters all of the related tags. +Except if a filter is applied with a (double) prefix-argument. + +Filtering in the agenda on subcategories does not filter the "above" +levels anymore. + +If a grouptag contains a regular expression the regular expression +is also used as a filter. + +*** Minor refactoring of ~org-agenda-filter-by-tag~ + +Now uses the argument ARG and optional argument exclude instead of +strip and narrow. ARG because the argument has multiple purposes and +makes more sense than strip now. The term "narrowing" is changed to +exclude. + +The main purpose is for the function to make more logical sense when +filtering on tags now when tags can be structured in hierarchies. + +*** Babel: support for sed scripts + +Thanks to Bjarte Johansen for this feature. + +*** Babel: support for Processing language + +New ob-processing.el library. + +This library implements necessary functions for implementing editing +of Processing code blocks, viewing the resulting sketches in an +external viewer, and HTML export of the sketches. + +Check the documentation for more details. + +Thanks to Jarmo Hurri for this feature. + +*** New behavior for ~org-toggle-latex-fragment~ + +The new behavior is the following: + +- With a double prefix argument or with a single prefix argument when + point is before the first headline, toggle overlays in the whole + buffer; + +- With a single prefix argument, toggle overlays in the current + subtree; + +- On latex code, toggle overlay at point; + +- Otherwise, toggle overlays in the current section. + +*** Additional markup with =#+INCLUDE= keyword + +The content of the included file can now be optionally marked up, for +instance as HTML. See the documentation for details. + +*** File links with =#+INCLUDE= keyword + +Objects can be extracted via =#+INCLUDE= using file links. It is +possible to include only the contents of the object. See manual for +more information. + +*** Drawers do not need anymore to be referenced in =#+DRAWERS= + +One can use a drawer without listing it in the =#+DRAWERS= keyword, +which is now obsolete. As a consequence, this change also deprecates +~org-drawers~ variable. + +*** ~org-edit-special~ can edit export blocks + +Using C-c ' on an export block now opens a sub-editing buffer. Major +mode in that buffer is determined by export backend name (e.g., +"latex" \to "latex-mode"). You can define exceptions to this rule by +configuring ~org-src-lang-modes~, which see. + +*** Additional =:hline= processing to ob-shell + +If the argument =:hlines yes= is present in a babel call, an optional +argument =:hlines-string= can be used to define a string to use as a +representation for the lisp symbol ='hline= in the shell program. The +default is =hline=. + +*** Markdown export supports switches in source blocks + +For example, it is now possible to number lines using the =-n= switch in +a source block. + +*** New option in ASCII export + +Plain lists can have an extra margin by setting ~org-ascii-list-margin~ +variable to an appropriate integer. + +*** New blocks in ASCII export + +ASCII export now supports =#+BEGIN_JUSTIFYRIGHT= and =#+BEGIN_JUSTIFYLEFT= +blocks.

It also provides +more features. See docstring for details. + +*** New function: ~org-element-copy~ + +*** New filter: ~org-export-filter-body-functions~ + +Functions in this filter are applied on the body of the exported +document, before wrapping it within the template. + +*** New :environment parameter when exporting example blocks to LaTeX + +: #+ATTR_LATEX: :environment myverbatim +: #+BEGIN_EXAMPLE +: This sentence is false. +: #+END_EXAMPLE + +will be exported using =@samp(myverbatim)= instead of =@samp(verbatim)=. + +*** Various improvements on radio tables + +Radio tables feature now relies on Org's export framework ("ox.el"). +~:no-escape~ parameter no longer exists, but additional global +parameters are now supported: ~:raw~, ~:backend~. Moreover, there are new +parameters specific to some pre-defined translators, e.g., +~:environment~ and ~:booktabs~ for ~orgtbl-to-latex~. See translators +docstrings (including ~orgtbl-to-generic~) for details. + +*** Non-floating minted listings in Latex export + +It is not possible to specify =#+attr_latex: :float nil= in conjunction +with source blocks exported by the minted package. + +*** Field formulas can now create columns as needed + +Previously, evaluating formulas that referenced out-of-bounds columns +would throw an error. A new variable ~org-table-formula-create-columns~ +was added to adjust this behavior. It is now possible to silently add +new columns, to do so with a warning or to explicitly ask the user +each time. + +*** ASCII plot + +Ability to plot values in a column through ASCII-art bars. See manual +for details. + +*** New hook: ~org-archive-hook~ + +This hook is called after successfully archiving a subtree, with point +on the original subtree, not yet deleted. + +*** New option: ~org-attach-archive-delete~ + +When non-nil, attachments from archived subtrees are removed. + +*** New option: ~org-latex-caption-above~ + +This variable generalizes ~org-latex-table-caption-above~, which is now +deprecated. In addition to tables, it applies to source blocks, +special blocks and images. See docstring for more information. + +*** New option: ~org-latex-prefer-user-labels~ + +See the docstring for more information. + +*** Export unnumbered headlines + +Headlines, for which the property ~UNNUMBERED~ is non-nil, are now +exported without section numbers irrespective of their levels. The +property is inherited by children. + +*** Tables can be sorted with an arbitrary function + +It is now possible to specify a function, both programmatically, +through a new optional argument, and interactively with ~f~ or ~F~ keys, +to sort a table. + +*** Table of contents can be local to a section + +The ~TOC~ keywords now accepts an optional ~local~ parameter. See manual +for details. + +*** Countdown timers can now be paused + +~org-timer-pause-time~ now pauses and restarts both relative and +countdown timers. + +*** New option ~only-window~ for ~org-agenda-window-setup~ + +When ~org-agenda-window-setup~ is set to ~only-window~, the agenda is +displayed as the sole window of the current frame. + +*** ~{{{date}}}~ macro supports optional formatting argument + +It is now possible to supply and optional formatting argument to +~{{{date}}}~.

See +manual for details. + +*** New option ~org-export-with-title~ + +It is possible to suppress the title insertion with ~#+OPTIONS: +title:nil~ or globally using the variable ~org-export-with-title~. + +*** New entities family: "\_ " + +"\_ " are used to insert up to 20 contiguous spaces in various +back-ends. In particular, this family can be used to introduce +leading spaces within table cells. + +*** New MathJax configuration options + +Org uses the MathJax CDN by default. See the manual and the docstring +of ~org-html-mathjax-options~ for details. + +*** New behavior in `org-export-options-alist' + +When defining a back-end, it is now possible to specify to give +`parse' behavior on a keyword. It is equivalent to call +`org-element-parse-secondary-string' on the value. + +However, parsed =KEYWORD= is automatically associated to an +=:EXPORT_KEYWORD:= property, which can be used to override the keyword +value during a subtree export. Moreover, macros are expanded in such +keywords and properties. + +*** Viewport support in html export + +Viewport for mobile-optimized website is now automatically inserted +when exporting to html.

This +export engine relies on ~org-element.el~ (Org's syntax parser), which was +already in Org's core. This new export engine triggered the rewriting of +/all/ export back-ends. + +The most visible change is the export dispatcher, accessible through the +keybinding =C-c C-e=. By default, this menu only shows some of the +built-in export formats, but you can add more formats by loading them +directly (e.g., =(require 'ox-texinfo)= or by configuring the option +[[doc:org-export-backends][org-export-backends]]. + +More contributed back-ends are available from the =contrib/= directory, the +corresponding files start with the =ox-= prefix. + +If you customized an export back-end (like HTML or LaTeX), you will need to +rename some options so that your customization is not lost. Typically, an +option starting with =org-export-html-= is now named =org-html-=. See the +manual for details and check [[https://orgmode.org/worg/org-8.0.html][this Worg page]] for directions. + +**** New syntax for #+ATTR_HTML/LaTeX/... options + + : #+ATTR_HTML width="200px" + + should now be written + + : #+ATTR_HTML :width 200px + + Keywords like =#+ATTR_HTML= and =#+ATTR_LaTeX= are defined in their + respective back-ends, and the list of supported parameters depends on + each backend. See Org's manual for details. + +**** ~org-remember.el~ has been removed + + You cannot use =remember.el= anymore to capture notes. + + Support for remember templates has been obsoleted since long, it is + now fully removed. + + Use =M-x org-capture-import-remember-templates RET= to import your + remember templates into capture templates. + +**** ~org-jsinfo.el~ has been merged into ~ox-html.el~ + + If you were requiring ~ox-jsinfo.el~ in your ~.emacs.el~ file, you + will have to remove this requirement from your initialization file. + +**** Note for third-party developers + + The name of the files for export back-end have changed: we now use the + prefix =ox-= for those files (like we use the =ob-= prefix for Babel + files.) For example ~org-html.el~ is now ~ox-html.el~. + + If your code relies on these files, please update the names in your + code. + +**** Packages moved from core to contrib + + Since packages in Org's core are meant to be part of GNU Emacs, we try + to be minimalist when it comes to adding files into core. For 8.0, we + moved some contributions into the =contrib/= directory. + + The rationale for deciding that these files should live in =contrib/= + is either because they rely on third-party software that is not + included in Emacs, or because they are not targeting a significant + user-base. + + - org-colview-xemacs.el + - org-mac-message.el + - org-mew.el + - org-wl.el + - ox-freedmind.el + - ox-taskjuggler.el + + Note that ~ox-freedmind.el~ has been rewritten by Jambunathan, + ~org-mew.el~ has been enhanced by Tokuya Kameshima and + ~ox-taskjuggler.el~ by Nicolas Goaziou and others. + + Also, the Taskjuggler exporter now uses TJ3 by default.

It has been updated and includes new options. + +Among the new/updated export options, three are of particular importance: + +- [[doc:org-export-allow-bind-keywords][org-export-allow-bind-keywords]] :: This option replaces the old option + =org-export-allow-BIND= and the default value is =nil=, not =confirm=. + You will need to explicitly set this to =t= in your initialization + file if you want to allow =#+BIND= keywords. + +- [[doc:org-export-with-planning][org-export-with-planning]] :: This new option controls the export of + =SCHEDULED:, DEADLINE:, CLOSED:= lines, and planning information is + now skipped by default during export. This use to be the job of + [[doc:org-export-with-timestamps][org-export-with-timestamps]], but this latter option has been given a + new role: it controls the export of /standalone time-stamps/. When + set to =nil=, Org will not export active and inactive time-stamps + standing on a line by themselves or within a paragraph that only + contains time-stamps. + +To check if an option has been introduced or its default value changed in +Org 8.0, do =C-h v [option] RET= and check if the documentation says that +the variable has been introduced (or changed) in version 24.4 of Emacs. + +**** Enhanced default stylesheet for the HTML exporter + +See the new default value of [[doc:org-html-style-default][org-html-style-default]]. + +**** New tags, classes and ids for the HTML exporter + +See the new default value of [[doc:org-html-divs][org-html-divs]]. + +**** Support for tikz pictures in LaTeX export +**** ~org-man.el~: New export function for "man" links +**** ~org-docview.el~: New export function for docview links +*** Structure editing + +**** =C-u C-u M-RET= inserts a heading at the end of the parent subtree +**** Cycling to the =CONTENTS= view keeps inline tasks folded + +[[doc:org-cycle-hook][org-cycle-hook]] as a new function [[doc:org-cycle-hide-inline-tasks][org-cycle-hide-inline-tasks]] which +prevents the display of inline tasks when showing the content of a subtree. + +**** =C-c -= in a region makes a list item for each line + +This is the opposite of the previous behavior, where =C-c -= on a region +would create one item for the whole region, and where =C-u C-c -= would +create an item for each line. Now =C-c -= on the selected region creates +an item per line, and =C-u C-c -= creates a single item for the whole +region. + +**** When transposing words, markup characters are now part of the words + +In Emacs, you can transpose words with =M-t=. Transposing =*these* +_words__= will preserve markup. + +**** New command [[doc:org-set-property-and-value][org-set-property-and-value]] bound to =C-c C-x P= + +This command allows you to quickly add both the property and its value. It +is useful in buffers where there are many properties and where =C-c C-x p= +can slow down the flow of editing too much. + +**** New commands [[doc:org-next-block][org-next-block]] and [[doc:org-previous-block][org-previous-block]] + +These commands allow you to go to the previous block (=C-c M-b= or the +speedy key =B=) or to the next block (=C-c M-f= or the speedy key =F=.) + +**** New commands [[doc:org-drag-line-forward][org-drag-line-forward]] and [[doc:org-drag-line-backward][org-drag-line-backward]] + +These commands emulate the old behavior of =M-= and =M-= but are +now bound to =S-M-= and =S-M-= respectively, since =M-= and +=M-= now drag the whole element at point (a paragraph, a table, etc.) +forward and backward. + +**** When a list item has a checkbox, inserting a new item uses a checkbox too +**** When sorting entries/items, only the description of links is considered + +Now Org will sort this list + +: - [[https://abc.org][B]] +: - [[https://def.org][A]] + +like this: + +: - [[https://def.org][A]] +: - [[https://abc.org][B]] + +by comparing the descriptions, not the links. +Same when sorting headlines instead of list items. +**** New option =orgstruct-heading-prefix-regexp= + +For example, setting this option to "^;;; " in Emacs lisp files and using +=orgstruct-mode= in those files will allow you to cycle through visibility +states as if lines starting with ";;; *..." where headlines. + +In general, you want to set =orgstruct-heading-prefix-regexp= as a file +local variable. + +**** New behavior of [[doc:org-clone-subtree-with-time-shift][org-clone-subtree-with-time-shift]] + +The default is now to ask for a time-shift only when there is a time-stamp. +When called with a universal prefix argument =C-u=, it will not ask for a +time-shift even if there is a time-stamp. + +**** New option [[doc:org-agenda-restriction-lock-highlight-subtree][org-agenda-restriction-lock-highlight-subtree]] + +This defaults to =t= so that the whole subtree is highlighted when you +restrict the agenda view to it with =C-c C-x <= (or the speed command =<=). +The default setting helps ensuring that you are not adding tasks after the +restricted region. If you find this highlighting too intrusive, set this +option to =nil=. +**** New option [[doc:org-closed-keep-when-no-todo][org-closed-keep-when-no-todo]] + +When switching back from a =DONE= keyword to a =TODO= keyword, Org now +removes the =CLOSED= planning information, if any.

The +task is still scheduled on the 25th but will appear in your agenda starting +from two days later (i.e. from March 27th.) + +Imagine for example that your co-workers are not done in due time and tell +you "we need two more days". In that case, you may want to delay the +display of the task in your agenda by two days, but you still want the task +to appear as scheduled on March 25th. + +In case the task contains a repeater, the delay is considered to affect all +occurrences; if you want the delay to only affect the first scheduled +occurrence of the task, use =--2d= instead.

This is useful when you +want to build a list of appointments. + +You can also set [[doc:org-agenda-entry-types][org-agenda-entry-types]] either globally or locally in +each agenda custom command and use =:timestamp*= and/or =:deadline*= there. + +Another place where this is useful is your =.diary= file: + +: %%(org-diary :scheduled*) ~/org/rdv.org + +This will list only entries from =~/org/rdv.org= that are scheduled with a +time value (i.e. appointments). + +**** New agenda sorting strategies + +[[doc:org-agenda-sorting-strategy][org-agenda-sorting-strategy]] allows these new sorting strategies: + +| Strategy | Explanations | +|----------------+------------------------------------------| +| timestamp-up | Sort by any timestamp, early first | +| timestamp-down | Sort by any timestamp, late first | +| scheduled-up | Sort by scheduled timestamp, early first | +| scheduled-down | Sort by scheduled timestamp, late first | +| deadline-up | Sort by deadline timestamp, early first | +| deadline-down | Sort by deadline timestamp, late first | +| ts-up | Sort by active timestamp, early first | +| ts-down | Sort by active timestamp, late first | +| tsia-up | Sort by inactive timestamp, early first | +| tsia-down | Sort by inactive timestamp, late first | + +**** New options to limit the number of agenda entries + +You can now limit the number of entries in an agenda view. This is +different from filters: filters only /hide/ the entries in the agenda, +while limits are set while generating the list of agenda entries. + +These new options are available: + +- [[doc:org-agenda-max-entries][org-agenda-max-entries]] :: limit by number of entries. +- [[doc:org-agenda-max-todos][org-agenda-max-todos]] :: limit by number of TODOs. +- [[doc:org-agenda-max-tags][org-agenda-max-tags]] :: limit by number of tagged entries. +- [[doc:org-agenda-max-effort][org-agenda-max-effort]] :: limit by effort (minutes). + +For example, if you locally set [[doc:org-agenda-max-todos][org-agenda-max-todos]] to 3 in an agenda +view, the agenda will be limited to the first three todos. Other entries +without a TODO keyword or beyond the third TODO headline will be ignored. + +When setting a limit (e.g. about an effort's sum), the default behavior is +to exclude entries that cannot be checked against (e.g. entries that have +no effort property.) To include other entries too, you can set the limit +to a negative number. For example =(setq org-agenda-max-tags -3)= will not +show the fourth tagged headline (and beyond), but it will also show +non-tagged headlines. + +**** =~= in agenda view sets temporary limits + +You can hit =~= in the agenda to temporarily set limits: this will +regenerate the agenda as if the limits were set. This is useful for +example when you want to only see a list of =N= tasks, or a list of tasks +that take only =N= minutes. + +**** "=" in agenda view filters by regular expressions + +You can now filter agenda entries by regular expressions using ~=~. =C-u +== will filter entries out.

It copies the +headlines and their content (but not subheadings) into the new file. + +This is useful when you want to quickly share an agenda containing the full +list of notes. + +**** New commands to drag an agenda line forward (=M-=) or backward (=M-=) + +It sometimes handy to move agenda lines around, just to quickly reorganize +your tasks, or maybe before saving the agenda to a file. Now you can use +=M-= and =M-= to move the line forward or backward. + +This does not persist after a refresh of the agenda, and this does not +change the =.org= files who contribute to the agenda. + +**** Use =%b= for displaying "breadcrumbs" in the agenda view + +[[doc:org-agenda-prefix-format][org-agenda-prefix-format]] now allows to use a =%b= formatter to tell Org +to display "breadcrumbs" in the agenda view. + +This is useful when you want to display the task hierarchy in your agenda. + +**** Use =%l= for displaying the headline's level in the agenda view + +[[doc:org-agenda-prefix-format][org-agenda-prefix-format]] allows to use a =%l= formatter to tell Org to +display entries with additional spaces corresponding to their level in the +outline tree. + +**** [[doc:org-agenda-write][org-agenda-write]] will ask before overwriting an existing file + +=M-x org-agenda-write RET= (or =C-c C-w= from an agenda buffer) used to +overwrite preexisting file with the same name without confirmation.

Etc. + + Note that if point is at the beginning of a list, it will mark + the whole list. + + To mark a subtree, you can either use =M-h= on the headline + (since there is no ambiguity about the element you're at) or + [[doc::org-mark-subtree][org-mark-subtree]] (=C-c @=) anywhere in the subtree. + + Invoking [[doc::org-mark-element][org-mark-element]] repeatedly will try to mark the next + element on top of the previous one(s). E.g. hitting =M-h= twice + on a headline will mark the current subtree and the next one on + the same level. + +*** Org Agenda + +**** New option [[doc::org-agenda-sticky][org-agenda-sticky]] + + There is a new option =org-agenda-sticky= which enables "sticky" + agendas. Sticky agendas remain opened in the background so that + you don't need to regenerate them each time you hit the + corresponding keystroke. This is a big time saver. + + When [[doc::org-agenda-sticky][org-agenda-sticky]] is =non-nil=, the agenda buffer will be + named using the agenda key and its description. In sticky + agendas, the =q= key will just bury the agenda buffers and + further agenda commands will show existing buffer instead of + generating new ones. + + If [[doc::org-agenda-sticky][org-agenda-sticky]] is set to =nil=, =q= will kill the single + agenda buffer. + +**** New option [[doc::org-agenda-custom-commands-contexts][org-agenda-custom-commands-contexts]] + + Setting this option allows you to define specific context where + agenda commands should be available from.

If you are on an entry with a timestamp, you + will be prompted for a date to reschedule your marked entries to, + using the timestamp at point as the default prompt. + + You can now use =k= to capture the marked entry and use the date + at point as an overriding date for the capture template. + + To bind this behavior to =M-x org-capture RET= (or its + keybinding), set the new option [[doc::org-capture-use-agenda-date][org-capture-use-agenda-date]] to + =t=. + +**** =N= and =P= in the agenda will move to the next/previous item + +**** New command [[doc::org-agenda-bulk-mark-all][org-agenda-bulk-mark-all]] to mark all items + + This new command is bound to =*= in agenda mode. + + There is also a new option [[doc::org-agenda-bulk-mark-char][org-agenda-bulk-mark-char]] to set the + character to use as a mark for bulk actions. + +**** New option [[doc::org-agenda-persistent-marks][org-agenda-persistent-marks]] + + When set to =non-nil=, marks will remain visible after a bulk + action.

Pressing "<" will + filter by the category of the item on the current line, and + pressing "<" again will remove the filter. You can combine tag + filters and category filters. + + You can use =org-agenda-category-filter= in your custom agenda + views and =org-agenda-category-filter-preset= in your main + configuration. + + See also the new command [[doc::org-agenda-filter-by-top-category][org-agenda-filter-by-top-category]]: + hitting =^= will filter by "Top" category: only show entries that + are of the same category than the Top category of the entry at + point. + +*** Org Links + +**** Inserting links + + When inserting links through [[doc::org-insert-link][org-insert-link]], the description is + now displayed first, followed by the literal link, as the + description is often more useful when you look for the link you + want to insert. + + Completion now complete both literal links and description. If + you complete a description, the literal link and its description + will be inserted directly, whereas when you complete the literal + link, you will be prompted for a description (as with Org 7.8.) + + In the completion buffer, links to the current buffer are now + highlighted. + +**** New templates =%h= and =%(sexp)= for abbreviated links + + On top of =%s= template, which is replaced by the link tag in + abbreviated links, you can now use =%h= (which does the same than =%s= + but does not hexify the tag) and =%(sexp)= (which can run a function + that takes the tag as its own argument.) + +**** New link type =help= + + You can now create links from =help= buffers. + + For example, if you request help for the command [[doc::org-agenda][org-agenda]] with + =C-h f org-agenda RET=, creating a link from this buffer will let + you go back to the same buffer. + +**** New command [[doc::org-insert-all-links][org-insert-all-links]] + + This will insert all links as list items.

This setup makes it difficult to + maintain the list of packages that Org itself would like to call, + for example for the special symbol support it needs. + + First of all, you can *opt out of this change* in the following + way: You can say: /I want to have full control over headers, and I + will take responsibility to include the packages Org needs/. If + that is what you want, add this to your configuration and skip the + rest of this section (except maybe for the description of the + =[EXTRA]= place holder): + + #+begin_src emacs-lisp + (setq org-export-latex-default-packages-alist nil + org-export-latex-packages-alist nil) + #+end_src + + /Continue to read here if you want to go along with the modified + setup./ + + There are now two variables that should be used to list the LaTeX + packages that need to be included in all classes. The header + definition in =org-export-latex-classes= should then not contain + the corresponding =\usepackage= calls (see below). + + The two new variables are: + + 1. =org-export-latex-default-packages-alist= :: This is the + variable where Org-mode itself puts the packages it needs. + Normally you should not change this variable. The only + reason to change it anyway is when one of these packages + causes a conflict with another package you want to use. Then + you can remove that packages and hope that you are not using + Org-mode functionality that needs it. + + 2. =org-export-latex-packages-alist= :: This is the variable where + you can put the packages that you'd like to use across all + classes. + + The sequence how these customizations will show up in the LaTeX + document are: + + 1. Header from =org-export-latex-classes= + 2. =org-export-latex-default-packages-alist= + 3. =org-export-latex-packages-alist= + 4. Buffer-specific things set with =#+LaTeX_HEADER:= + + If you want more control about which segment is placed where, or + if you want, for a specific class, have full control over the + header and exclude some of the automatic building blocks, you can + put the following macro-like place holders into the header: + + #+begin_example + [DEFAULT-PACKAGES] \usepackage statements for default packages + [NO-DEFAULT-PACKAGES] do not include any of the default packages + [PACKAGES] \usepackage statements for packages + [NO-PACKAGES] do not include the packages + [EXTRA] the stuff from #+LaTeX_HEADER + [NO-EXTRA] do not include #+LaTeX_HEADER stuff + #+end_example + + If you have currently customized =org-export-latex-classes=, you + should revise that customization and remove any package calls that + are covered by =org-export-latex-default-packages-alist=.

But then you risk that + some of the advertised export features of Org will not work + properly. + + You can also consider moving packages that you use in all classes + to =org-export-latex-packages-alist=. If necessary, put the place + holders so that the packages get loaded in the right sequence. As + said above, for backward compatibility, if you omit the place + holders, all the variables will dump their content at the end of + the header. + +*** The constant =org-html-entities= is obsolete + + Its content is now part of the new constant =org-entities=, which + is defined in the file org-entities.el. =org-html-entities= was + an internal variable, but it is possible that some users did write + code using it. + +*** =org-bbdb-anniversary-format-alist= has changed + + Please check the docstring and update your settings accordingly. + +*** Deleted =org-mode-p= + + This function has been deleted: please update your code. + +** Important new features + +*** New Org to ODT exporter + + Jambunathan's Org to ODT exporter is now part of Org. + + To use it, it `C-c C-e o' in an Org file.

See + [[msg:C46F10DC-DE51-43D4-AFFE-F71E440D1E1F@gmail.com][Carsten's announcement]] for more details. + + To switch over to the new system: + + 1. Run + + : M-x org-capture-import-remember-templates RET + + to get a translated version of your remember templates into the + new variable =org-capture-templates=. This will "mostly" work, + but maybe not for all cases. At least it will give you a good + place to modify your templates. After running this command, + enter the customize buffer for this variable with + + : M-x customize-variable RET org-capture-templates RET + + and convince yourself that everything is OK. Then save the + customization. + + 2. Bind the command =org-capture= to a key, similar to what you did + with org-remember: + + : (define-key global-map "\C-cc" 'org-capture) + + If your fingers prefer =C-c r=, you can also use this key once + you have decided to move over completely to the new + implementation.

This package generalizes them (at least for the + LaTeX and html exporters). When a #+begin_foo token is + encountered by the LaTeX exporter, it is expanded + into \begin{foo}. The text inside the environment is not + protected, as text inside environments generally is. + When #+begin_foo is encountered by the html exporter, a div with + class foo is inserted into the HTML file. It is up to the user + to add this class to his or her stylesheet if this div is to mean + anything. + +**** org-taskjuggler.el (Christian Egli) + + Christian Egli's /org-taskjuggler.el/ module is now part of Org. + He also wrote a [[https://orgmode.org/worg/org-tutorials/org-taskjuggler.php][tutorial]] for it. + +**** org-ctags.el (Paul Sexton) + + Targets like =<>= can now be found by Emacs' etag + functionality, and Org-mode links can be used to to link to + etags, also in non-Org-mode files. For details, see the file + /org-ctags.el/. + + This feature uses a new hook =org-open-link-functions= which will + call function to do something special with text links. + + Thanks to Paul Sexton for this contribution. + +**** org-docview.el (Jan Böcker) + + This new module allows links to various file types using docview, where + Emacs displays images of document pages. Docview link types can point + to a specific page in a document, for example to page 131 of the + Org-mode manual: + + : [[docview:~/.elisp/org/doc/org.pdf::131][Org-Mode Manual]] + + Thanks to Jan Böcker for this contribution. + +*** New Babel libraries + +- ob-picolisp.el (Thorsten Jolitz) +- ob-fortran.el (Sergey Litvinov) +- ob-shen.el (Eric Schulte) +- ob-maxima.el (Eric S Fraga) +- ob-java.el (Eric Schulte) +- ob-lilypond.el (Martyn Jago) +- ob-awk.el (Eric Schulte) + +** Other new features and various enhancements + +*** Hyperlinks + +**** Org-Bibtex -- major improvements + + Provides support for managing bibtex bibliographical references + data in headline properties. Each headline corresponds to a + single reference and the relevant bibliographic meta-data is + stored in headline properties, leaving the body of the headline + free to hold notes and comments. Org-bibtex is aware of all + standard bibtex reference types and fields. + + The key new functions are + + - org-bibtex-check :: queries the user to flesh out all required + (and with prefix argument optional) bibtex fields available + for the specific reference =type= of the current headline. + + - org-bibtex-create :: Create a new entry at the given level, + using org-bibtex-check to flesh out the relevant fields. + + - org-bibtex-yank :: Yank a bibtex entry on the kill ring as a + formatted Org-mode headline into the current buffer + + - org-bibtex-export-to-kill-ring :: Export the current headline + to the kill ring as a formatted bibtex entry. + +**** org-gnus.el now allows link creation from messages + + You can now create links from messages. This is particularly + useful when the user wants to stored messages that he sends, for + later check. Thanks to Ulf Stegemann for the patch. + +**** Modified link escaping + + David Maus worked on `org-link-escape'. See [[msg:87k4gysacq.wl%dmaus@ictsoc.de][his message]]: + + : Percent escaping is used in Org mode to escape certain characters + : in links that would either break the parser (e.g. square brackets + : in link target or description) or are not allowed to appear in + : a particular link type (e.g. non-ascii characters in a http: + : link). + : + : With this change in place Org will apply percent escaping and + : unescaping more consistently especially for non-ascii characters. + : Additionally some of the outstanding bugs or glitches concerning + : percent escaped links are solved. + + Thanks a lot to David for this work. + +**** Make =org-store-link= point to directory in a dired buffer + + When, in a dired buffer, the cursor is not in a line listing a + file, `org-store-link' will store a link to the directory. + + Patch by Stephen Eglen. + +**** Allow regexps in =org-file-apps= to capture link parameters + + The way extension regexps in =org-file-apps= are handled has + changed. Instead of matching against the file name, the regexps + are now matched against the whole link, and you can use grouping + to extract link parameters which you can then use in a command + string to be executed. + + For example, to allow linking to PDF files using the syntax + =file:/doc.pdf::=, you can add the following entry + to org-file-apps: + + #+begin_example + Extension: \.pdf::\([0-9]+\)\' + Command: evince "%s" -p %1 + #+end_example + + Thanks to Jan Böcker for a patch to this effect. + +*** Dates and time + +**** Allow relative time when scheduling/adding a deadline + + You can now use relative duration strings like "-2d" or "++3w" + when calling =org-schedule= or =org-deadline=: it will schedule + (or set the deadline for) the item respectively two days before + today and three weeks after the current timestamp, if any. + + You can use this programmatically: =(org-schedule nil "+2d")= + will work on the current entry. + + You can also use this while (bulk-)rescheduling and + (bulk-)resetting the deadline of (several) items from the agenda. + + Thanks to Memnon Anon for a heads up about this! + +**** American-style dates are now understood by =org-read-date= + + So when you are prompted for a date, you can now answer like this + + #+begin_example + 2/5/3 --> 2003-02-05 + 2/5 --> -02-05 + #+end_example + +*** Agenda + +**** =org-agenda-custom-commands= has a default value + + This option used to be `nil' by default. This now has a default + value, displaying an agenda and all TODOs. See the docstring for + details. Thanks to Carsten for this. + +**** Improved filtering through =org-agenda-to-appt= + + The new function allows the user to refine the scope of entries + to pass to =org-agenda-get-day-entries= and allows to filter out + entries using a function. + + Thanks to Peter Münster for raising a related issue and to + Tassilo Horn for this idea. Also thanks to Peter Münster for + [[git:68ffb7a7][fixing a small bug]] in the final implementation. + +**** Allow ap/pm times in agenda time grid + + Times in the agenda can now be displayed in am/pm format. See + the new variable =org-agenda-timegrid-use-ampm=. Thanks to + C. A. Webber for a patch to this effect. + +**** Agenda: Added a bulk "scattering" command + + =B S= in the agenda buffer will cause tasks to be rescheduled a + random number of days into the future, with 7 as the default. + This is useful if you've got a ton of tasks scheduled for today, + you realize you'll never deal with them all, and you just want + them to be distributed across the next N days. When called with + a prefix arg, rescheduling will avoid weekend days. + + Thanks to John Wiegley for this. + +*** Exporting + +**** Simplification of org-export-html-preamble/postamble + + When set to `t', export the preamble/postamble as usual, honoring + the =org-export-email/author/creator-info= variables. + + When set to a formatting string, insert this string. See the + docstring of these variable for details about available + %-sequences. + + You can set =:html-preamble= in publishing project in the same + way: `t' means to honor =:email/creator/author-info=, and a + formatting string will insert a string. + +**** New exporters to Latin-1 and UTF-8 + + While Ulf Stegemann was going through the entities list to + improve the LaTeX export, he had the great idea to provide + representations for many of the entities in Latin-1, and for all + of them in UTF-8. This means that we can now export files rich + in special symbols to Latin-1 and to UTF-8 files. These new + exporters can be reached with the commands =C-c C-e n= and =C-c + C-e u=, respectively. + + When there is no representation for a given symbol in the + targeted coding system, you can choose to keep the TeX-macro-like + representation, or to get an "explanatory" representation. For + example, =\simeq= could be represented as "[approx. equal to]". + Please use the variable =org-entities-ascii-explanatory= to state + your preference. + +**** HTML export: Add class to outline containers using property + + The =HTML_CONTAINER_CLASS= property can now be used to add a + class name to the outline container of a node in HTML export. + +**** Throw an error when creating an image from a LaTeX snippet fails + + This behavior can be configured with the new option variable + =org-format-latex-signal-error=. + +**** Support for creating BEAMER presentations from Org-mode documents + + Org-mode documents or subtrees can now be converted directly in + to BEAMER presentation. Turning a tree into a simple + presentations is straight forward, and there is also quite some + support to make richer presentations as well. See the [[https://orgmode.org/manual/Beamer-class-export.html#Beamer-class-export][BEAMER + section]] in the manual for more details. + + Thanks to everyone who has contributed to the discussion about + BEAMER support and how it should work. This was a great example + for how this community can achieve a much better result than any + individual could. + +*** Refiling + +**** Refile targets can now be cached + + You can turn on caching of refile targets by setting the variable + =org-refile-use-cache=. This should speed up refiling if you + have many eligible targets in many files. If you need to update + the cache because Org misses a newly created entry or still + offers a deleted one, press =C-0 C-c C-w=. + +**** New logging support for refiling + + Whenever you refile an item, a time stamp and even a note can be + added to this entry. For details, see the new option + =org-log-refile=. + + Thanks to Charles Cave for this idea. + +*** Completion + +**** In-buffer completion is now done using John Wiegley's pcomplete.el + + Thanks to John Wiegley for much of this code. + +*** Tables + +**** New command =org-table-transpose-table-at-point= + + See the docstring. This hack from Juan Pechiar is now part of + Org's core. Thanks to Juan! + +**** Display field's coordinates when editing it with =C-c `= + + When editing a field with =C-c `=, the field's coordinate will + the displayed in the buffer. + + Thanks to Michael Brand for a patch to this effect. + +**** Spreadsheet computation of durations and time values + + If you want to compute time values use the =T= flag, either in + Calc formulas or Elisp formulas: + + | Task 1 | Task 2 | Total | + |--------+--------+---------| + | 35:00 | 35:00 | 1:10:00 | + #+TBLFM: @2$3=$1+$2;T + + Values must be of the form =[HH:]MM:SS=, where hours are + optional. + + Thanks to Martin Halder, Eric Schulte and Carsten for code and + feedback on this. + +**** Implement formulas applying to field ranges + + Carsten implemented this field-ranges formulas. + + : A frequently requested feature for tables has been to be able to define + : row formulas in a way similar to column formulas. The patch below allows + : things like + : + : @3= + : @2$2..@5$7= + : @I$2..@II$4= + : + : as the left hand side for table formulas in order to write a formula that + : is valid for an entire column or for a rectangular section in a + : table. + + Thanks a lot to Carsten for this. + +**** Sending radio tables from org buffers is now allowed + + Org radio tables can no also be sent inside Org buffers. Also, + there is a new hook which get called after a table has been sent. + + Thanks to Seweryn Kokot. + +*** Lists + +**** Improved handling of lists + + Nicolas Goaziou extended and improved the way Org handles lists. + + 1. Indentation of text determines again end of items in + lists. So, some text less indented than the previous item + doesn't close the whole list anymore, only all items more + indented than it. + + 2. Alphabetical bullets are implemented, through the use of the + variable `org-alphabetical-lists'. This also adds alphabetical + counters like [@c] or [@W]. + + 3. Lists can now safely contain drawers, inline tasks, or various + blocks, themselves containing lists. Two variables are + controlling this: `org-list-forbidden-blocks', and + `org-list-export-context'. + + 4. Improve `newline-and-indent' (C-j): used in an item, it will + keep text from moving at column 0. This allows to split text + and make paragraphs and still not break the list. + + 5. Improve `org-toggle-item' (C-c -): used on a region with + standard text, it will change the region into one item. With a + prefix argument, it will fallback to the previous behavior and + make every line in region an item. It permits to easily + integrate paragraphs inside a list. + + 6. `fill-paragraph' (M-q) now understands lists. It can freely be + used inside items, or on text just after a list, even with no + blank line around, without breaking list structure. + + Thanks a lot to Nicolas for all this! + +*** Inline display of linked images + + Images can now be displayed inline. The key C-c C-x C-v does + toggle the display of such images. Note that only image links + that have no description part will be inlined. + +*** Implement offsets for ordered lists + + If you want to start an ordered plain list with a number different + from 1, you can now do it like this: + + : 1. [@start:12] will star a lit a number 12 + +*** Babel: code block body expansion for table and preview + + In org-babel, code is "expanded" prior to evaluation. I.e. the + code that is actually evaluated comprises the code block contents, + augmented with the extra code which assigns the referenced data to + variables. It is now possible to preview expanded contents, and + also to expand code during during tangling. This expansion takes + into account all header arguments, and variables. + + A new keybinding `C-c M-b p' bound to `org-babel-expand-src-block' + can be used from inside of a source code block to preview its + expanded contents (which can be very useful for debugging). + tangling + + The expanded body can now be tangled, this includes variable + values which may be the results of other source-code blocks, or + stored in headline properties or tables. One possible use for this + is to allow those using org-babel for their emacs initialization + to store values (e.g. usernames, passwords, etc...) in headline + properties or in tables. + + Org-babel now supports three new header arguments, and new default + behavior for handling horizontal lines in tables (hlines), column + names, and rownames across all languages. + +*** Editing Convenience and Appearance + +**** New command =org-copy-visible= (=C-c C-x v=) + + This command will copy the visible text in the region into the + kill ring. Thanks to Florian Beck for this function and to + Carsten for adding it to org.el and documenting it! + +**** Make it possible to protect hidden subtrees from being killed by =C-k= + + See the new variable =org-ctrl-k-protect-subtree=. This was a + request by Scott Otterson. + +**** Implement pretty display of entities, sub-, and superscripts. + + The command =C-c C-x \= toggles the display of Org's special + entities like =\alpha= as pretty unicode characters. Also, sub + and superscripts are displayed in a pretty way (raised/lower + display, in a smaller font). If you want to exclude sub- and + superscripts, see the variable + =org-pretty-entities-include-sub-superscripts=. + + Thanks to Eric Schulte and Ulf Stegeman for making this possible. + +**** New faces for title, date, author and email address lines + + The keywords in these lines are now dimmed out, and the title is + displayed in a larger font, and a special font is also used for + author, date, and email information. This is implemented by the + following new faces: + + =org-document-title= + =org-document-info= + =org-document-info-keyword= + + In addition, the variable =org-hidden-keywords= can be used to + make the corresponding keywords disappear. + + Thanks to Dan Davison for this feature. + +**** Simpler way to specify faces for tags and todo keywords + + The variables =org-todo-keyword-faces=, =org-tag-faces=, and + =org-priority-faces= now accept simple color names as + specifications. The colors will be used as either foreground or + background color for the corresponding keyword. See also the + variable =org-faces-easy-properties=, which governs which face + property is affected by this setting. + + This is really a great simplification for setting keyword faces. + The change is based on an idea and patch by Ryan Thompson. + +**** in tables now means fixed width, not maximum width + + Requested by Michael Brand. + +**** Better level cycling function + + =TAB= in an empty headline cycles the level of that headline + through likely states. Ryan Thompson implemented an improved + version of this function, which does not depend upon when exactly + this command is used. Thanks to Ryan for this improvement. + +**** Adaptive filling + + For paragraph text, =org-adaptive-fill-function= did not handle + the base case of regular text which needed to be filled. This is + now fixed. Among other things, it allows email-style ">" + comments to be filled correctly. + + Thanks to Dan Hackney for this patch. + +**** `org-reveal' (=C-c C-r=) also decrypts encrypted entries (org-crypt.el) + + Thanks to Richard Riley for triggering this change. + +**** Better automatic letter selection for TODO keywords + + When all first letters of keywords have been used, Org now + assigns more meaningful characters based on the keywords. + + Thanks to Mikael Fornius for this patch. + +*** Clocking + +**** Clock: Allow synchronous update of timestamps in CLOCK log + + Using =S-M-= on CLOCK log timestamps will + increase/decrease the two timestamps on this line so that + duration will keep the same. Note that duration can still be + slightly modified in case a timestamp needs some rounding. + + Thanks to Rainer Stengele for this idea. + +**** Localized clock tables + + Clock tables now support a new new =:lang= parameter, allowing + the user to customize the localization of the table headers. See + the variable =org-clock-clocktable-language-setup= which controls + available translated strings. + +**** Show clock overruns in mode line + + When clocking an item with a planned effort, overrunning the + planned time is now made visible in the mode line, for example + using the new face =org-mode-line-clock-overrun=, or by adding an + extra string given by =org-task-overrun-text=. + + Thanks to Richard Riley for a patch to this effect. + +**** Clock reports can now include the running, incomplete clock + + If you have a clock running, and the entry being clocked falls + into the scope when creating a clock table, the time so far spent + can be added to the total. This behavior depends on the setting + of =org-clock-report-include-clocking-task=. The default is + =nil=. + + Thanks to Bernt Hansen for this useful addition. + +*** Misc + +**** Improvements with inline tasks and indentation + + There is now a configurable way on how to export inline tasks. + See the new variable =org-inlinetask-export-templates=. + + Thanks to Nicolas Goaziou for coding these changes. + +**** A property value of =nil= now means to unset a property + + This can be useful in particular with property inheritance, if + some upper level has the property, and some grandchild of it + would like to have the default settings (i.e. not overruled by a + property) back. + + Thanks to Robert Goldman and Bernt Hansen for suggesting this + change. + +**** New helper functions in org-table.el + + There are new functions to access and write to a specific table field. + This is for hackers, and maybe for the org-babel people. + + #+begin_example + org-table-get + org-table-put + org-table-current-line + org-table-goto-line + #+end_example + +**** Archiving: Allow to reverse order in target node + + The new option =org-archive-reversed-order= allows to have + archived entries inserted in a last-on-top fashion in the target + node. + + This was requested by Tom. + +**** Org-reveal: Double prefix arg shows the entire subtree of the parent + + This can help to get out of an inconsistent state produced for + example by viewing from the agenda. + + This was a request by Matt Lundin. + +* License + + This file is part of GNU Emacs. + + GNU Emacs is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + GNU Emacs is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

LaTeX line +;; breaks are not necessary for TO_ADDRESS, FROM_ADDRESS and LOCATION. +;; If both a headline and a keyword specify a to or from address the +;; value is determined in accordance with +;; `org-koma-letter-prefer-special-headings'. +;; +;; A number of OPTIONS settings can be set to change which contents is +;; exported. +;; - backaddress (see `org-koma-letter-use-backaddress') +;; - foldmarks (see `org-koma-letter-use-foldmarks') +;; - phone (see `org-koma-letter-use-phone') +;; - url (see `org-koma-letter-use-url') +;; - from-logo (see `org-koma-letter-use-from-logo') +;; - email (see `org-koma-letter-use-email') +;; - place (see `org-koma-letter-use-place') +;; - location (see `org-koma-letter-use-location') +;; - subject, a list of format options +;; (see `org-koma-letter-subject-format') +;; - after-closing-order, a list of the ordering of headings with +;; special tags after closing (see +;; `org-koma-letter-special-tags-after-closing') +;; - after-letter-order, as above, but after the end of the letter +;; (see `org-koma-letter-special-tags-after-letter'). +;; +;; The following variables works differently from the main LaTeX class +;; - AUTHOR: Default to user-full-name but may be disabled. +;; (See also `org-koma-letter-author'.) +;; - EMAIL: Same as AUTHOR. (See also `org-koma-letter-email'.) +;; +;; FROM_LOGO uses LaTeX markup. FROM_LOGO provides the +;; "includegraphics" command to tell LaTeX where to find the logo. +;; This command needs to know the logo's directory and file name. The +;; directory can either be relative or absolute, just as you would +;; expect. LaTeX can use three file types for the logo: PDF, JPEG, or +;; PNG. The logo can either include or exclude its extension, which +;; might surprise you. When you exclude its extension, LaTeX will +;; search the directory for the "best" quality graphics format. For +;; example if it finds both logo.pdf and logo.png then it will +;; identify the PDF as "better", and include "logo.pdf". This can be +;; useful, for example, when you are mocking up a logo in the PNG +;; raster format and then switch over to the higher quality PDF vector +;; format. When you include the file extension then LaTeX will +;; include it without searching for higher quality file types. +;; Whatever file type you choose, it will probably require a few +;; design iterations to get the best looking logo size for your +;; letter. Finally, the directory and file name are specified +;; *without* quotes. Here are some examples with commentary, in the +;; location of your letter, with a logo named "logo", to get you +;; started: +;; +;; Logo in the same directory: \includegraphics{logo} +;; or a sub-directory: \includegraphics{logos/production/logo} +;; +;; Logos specified using absolute paths on Linux or Windows: +;; +;; \includegraphics{~/correspondence/logo} +;; \includegraphics{~/correspondence/logos/production/logo} +;; \includegraphics{c:/you/correspondence/logo} +;; \includegraphics{c:/you/correspondence/logos/production/logo} +;; +;; Logos in the same directory where the "better" quality PDF will +;; be chosen over the JPG: +;; +;; \includegraphics{logo.pdf} +;; \includegraphics{logo.png} +;; +;; Headlines are in general ignored. However, headlines with special +;; tags can be used for specified contents like postscript (ps), +;; carbon copy (cc), enclosures (encl) and code to be inserted after +;; \end{letter} (after_letter). Specials tags are defined in +;; `org-koma-letter-special-tags-after-closing' and +;; `org-koma-letter-special-tags-after-letter'. Currently members of +;; `org-koma-letter-special-tags-after-closing' used as macros and the +;; content of the headline is the argument. +;; +;; Headlines with to and from may also be used rather than the keyword +;; approach described above. If both a keyword and a headline with +;; information is present precedence is determined by +;; `org-koma-letter-prefer-special-headings'. +;; +;; You need an appropriate association in `org-latex-classes' in order +;; to use the KOMA Scrlttr2 class.
