;;; Commentary:
|
|
|
|
;; The `use-package' declaration macro allows you to isolate package
|
|
;; configuration in your ".emacs" in a way that is performance-oriented and,
|
|
;; well, just tidy. I created it because I have over 80 packages that I use
|
|
;; in Emacs, and things were getting difficult to manage. Yet with this
|
|
;; utility my total load time is just under 1 second, with no loss of
|
|
;; functionality!
|
|

|
|
;; Please see README.md from the same repository for documentation.

:byte-compile - package installed during byte-compilation

:ensure - package installed normally by :ensure

"Declare an Emacs package by specifying a group of configuration options.
|
|
|
|
For full documentation, please see the README file that came with
|
|
this file. Usage:
|
|
|
|
(use-package package-name
|
|
[:keyword [option]]...)
|
|
|
|
:init Code to run before PACKAGE-NAME has been loaded.
|
|
:config Code to run after PACKAGE-NAME has been loaded. Note that
|
|
if loading is deferred for any reason, this code does not
|
|
execute until the lazy load has occurred.
|
|
:preface Code to be run before everything except `:disabled'; this
|
|
can be used to define functions for use in `:if', or that
|
|
should be seen by the byte-compiler.
|
|
|
|
:mode Form to be added to `auto-mode-alist'.
|
|
:magic Form to be added to `magic-mode-alist'.
|
|
:magic-fallback Form to be added to `magic-fallback-mode-alist'.
|
|
:interpreter Form to be added to `interpreter-mode-alist'.
|
|
|
|
:commands Define autoloads for commands that will be defined by the
|
|
package. This is useful if the package is being lazily
|
|
loaded, and you wish to conditionally call functions in your
|
|
`:init' block that are defined in the package.
|
|
|
|
:bind Bind keys, and define autoloads for the bound commands.
|
|
:bind* Bind keys, and define autoloads for the bound commands,
|
|
*overriding all minor mode bindings*.
|
|
:bind-keymap Bind a key prefix to an auto-loaded keymap defined in the
|
|
package. This is like `:bind', but for keymaps.
|
|
:bind-keymap* Like `:bind-keymap', but overrides all minor mode bindings
|
|
|
|
:defer Defer loading of a package -- this is implied when using
|
|
`:commands', `:bind', `:bind*', `:mode', `:magic',
|
|
`:magic-fallback', or `:interpreter'. This can be an integer,
|
|
to force loading after N seconds of idle time, if the package
|
|
has not already been loaded.
|
|
|
|
:after Defer loading of a package until after any of the named
|
|
features are loaded.
|
|
|
|
:demand Prevent deferred loading in all cases.
|
|
|
|
:if EXPR Initialize and load only if EXPR evaluates to a non-nil value.
|
|
:disabled The package is ignored completely if this keyword is present.
|
|
:defines Declare certain variables to silence the byte-compiler.
|
|
:functions Declare certain functions to silence the byte-compiler.
|
|
:load-path Add to the `load-path' before attempting to load the package.
|
|
:diminish Support for diminish.el (if installed).
|
|
:delight Support for delight.el (if installed).
|
|
:custom Call `customize-set-variable' with each variable definition.
|
|
:custom-face Call `customize-set-faces' with each face definition.
|
|
:ensure Loads the package using package.el if necessary.
|
|
:pin Pin the package to an archive."
