A duration +;; can have multiple formats: +;; +;; - 3:12 +;; - 1:23:45 +;; - 1y 3d 3h 4min +;; - 1d3h5min +;; - 3d 13:35 +;; - 2.35h +;; +;; More accurately, it consists of numbers and units, as defined in +;; variable `org-duration-units', possibly separated with white +;; spaces, and an optional "H:MM" or "H:MM:SS" part, which always +;; comes last. White spaces are tolerated between the number and its +;; relative unit. Variable `org-duration-format' controls durations +;; default representation. +;; +;; The library provides functions allowing to convert a duration to, +;; and from, a number of minutes: `org-duration-to-minutes' and +;; `org-duration-from-minutes'. It also provides two lesser tools: +;; `org-duration-p', and `org-duration-h:mm-only-p'. +;; +;; Users can set the number of minutes per unit, or define new units, +;; in `org-duration-units'. The library also supports canonical +;; duration, i.e., a duration that doesn't depend on user's settings, +;; through optional arguments. + +;;; Code: + +(require 'cl-lib) +(require 'org-macs) + + +;;; Public variables + +(defconst org-duration-canonical-units + `(("min" . 1) + ("h" . 60) + ("d" . ,(* 60 24))) + "Canonical time duration units. +See `org-duration-units' for details.") + +(defcustom org-duration-units + `(("min" . 1) + ("h" . 60) + ("d" . ,(* 60 24)) + ("w" . ,(* 60 24 7)) + ("m" . ,(* 60 24 30)) + ("y" . ,(* 60 24 365.25))) + "Conversion factor to minutes for a duration. + +Each entry has the form (UNIT .
