This in turn enables `evil-local-mode' in +;; every buffer, which sets up the buffer's state. +;; +;; Each state has its own keymaps, and these keymaps have status as +;; "emulation keymaps" with priority over regular keymaps. Emacs +;; maintains the following keymap hierarchy (highest priority first): +;; +;; * Overriding keymaps/overlay keymaps... +;; * Emulation mode keymaps... +;; - Evil keymaps... +;; * Minor mode keymaps... +;; * Local keymap (`local-set-key') +;; * Global keymap (`global-set-key') +;; +;; Within this hierarchy, Evil arranges the keymaps for the current +;; state as shown below: +;; +;; * Intercept keymaps... +;; * Local state keymap +;; * Minor-mode keymaps... +;; * Auxiliary keymaps... +;; * Overriding keymaps... +;; * Global state keymap +;; * Keymaps for other states... +;; +;; These keymaps are listed in `evil-mode-map-alist', which is listed +;; in `emulation-mode-map-alist'. +;; +;; Most of the key bindings for a state are stored in its global +;; keymap, which has a name such as `evil-normal-state-map'. (See the +;; file evil-maps.el, which contains all the default key bindings.) A +;; state also has a local keymap (`evil-normal-state-local-map'), +;; which may contain user customizations for the current buffer. +;; Furthermore, any Emacs mode may be assigned state bindings of its +;; own by passing the mode's keymap to the function `evil-define-key' +;; or `evil-define-minor-mode-key'. The former uses a specific map to +;; define the key in while the latter associates the key with a +;; particular mode. These mode-specific bindings are ultimately stored +;; in so-called auxiliary and minor-mode keymaps respectively, which +;; are sandwiched between the local keymap and the global keymap. +;; Finally, the state may also activate the keymaps of other states +;; (e.g., Normal state inherits bindings from Motion state). +;; +;; For integration purposes, a regular Emacs keymap may be "elevated" +;; to emulation status by passing it to `evil-make-intercept-map' or +;; `evil-make-overriding-map'. An "intercept" keymap has priority over +;; all other Evil keymaps. (Evil uses this facility when debugging and +;; for handling the "ESC" key in the terminal.) More common is the +;; "overriding" keymap, which only has priority over the global state +;; keymap. (This is useful for adapting key-heavy modes such as Dired, +;; where all but a few keys should be left as-is and should not be +;; shadowed by Evil's default bindings.) +;; +;; States are defined with the macro `evil-define-state', which +;; creates a command for switching to the state. This command, +;; for example `evil-normal-state' for Normal state, performs +;; the following tasks: +;; +;; * Setting `evil-state' to the new state. +;; * Refreshing the keymaps in `evil-mode-map-alist'. +;; * Updating the mode line. +;; - Normal state depends on `evil-normal-state-tag'. +;; * Adjusting the cursor's appearance. +;; - Normal state depends on `evil-normal-state-cursor'. +;; * Displaying a message in the echo area. +;; - Normal state depends on `evil-normal-state-message'. +;; * Running hooks. +;; - Normal state runs `evil-normal-state-entry-hook' when +;; entering, and `evil-normal-state-exit-hook' when exiting. +;; +;; The various properties of a state can be accessed through their +;; respective variables, or by passing a keyword and the state's name +;; to the `evil-state-property' function.
