use-package can be installed using Emacs' package manager or manually from
its development repository.

@node Installing from GNU ELPA
@section Installing from GNU ELPA
use-package is available from GNU ELPA. If you haven't used
Emacs' package manager before, then it is high time you familiarize yourself
with it by reading the documentation in the Emacs manual, see
@ref{Packages,,,emacs,}. Then add one of the archives to @code{package-archives}:
First, you need to update the local package list using:
@example
M-x package-refresh-contents RET
@end example
Once you have done that, you can install use-package and its
dependencies using:
@example
M-x package-install RET use-package RET
@end example
Now see @ref{Post-Installation Tasks}.
@node Installing from the Git Repository
@section Installing from the Git Repository
First, use Git to clone the use-package repository:
@example
$ git clone https://github.com/jwiegley/use-package.git ~/.emacs.d/site-lisp/use-package
$ cd ~/.emacs.d/site-lisp/use-package
@end example
Then compile the libraries and generate the info manuals:
@example
$ make
@end example
You may need to create @code{/path/to/use-package/config.mk} with the following
content before running @code{make}:
@example
LOAD_PATH = -L /path/to/use-package
@end example
Finally add this to your init file:
@lisp
(add-to-list 'load-path "~/.emacs.d/site-lisp/use-package")
(require 'use-package)
(with-eval-after-load 'info
(info-initialize)
(add-to-list 'Info-directory-list
"~/.emacs.d/site-lisp/use-package/"))
@end lisp
Note that elements of @code{load-path} should not end with a slash, while those of
@code{Info-directory-list} should.
Instead of running use-package directly from the repository by adding it to
the @code{load-path}, you might want to instead install it in some other directory
using @code{sudo make install} and setting @code{load-path} accordingly.
To update use-package use:
@example
$ git pull
$ make
@end example
At times it might be necessary to run @code{make clean all} instead.
To view all available targets use @code{make help}.
Now see @ref{Post-Installation Tasks}.
@node Post-Installation Tasks
@section Post-Installation Tasks
After installing use-package you should verify that you are indeed using the
use-package release you think you are using. It's best to restart Emacs before
doing so, to make sure you are not using an outdated value for @code{load-path}.
@example
C-h v use-package-version RET
@end example
should display something like
@example
use-package-versions value is "2.4.3"
@end example
If you are completely new to use-package then see @ref{Getting Started}.
If you run into problems, then please see the @ref{Debugging Tools}.
@node Getting Started
@chapter Getting Started
TODO@. For now, see @code{README.md}.
@node Basic Concepts
@chapter Basic Concepts
@code{use-package} was created for few basic reasons, each of which drove the
design in various ways. Understanding these reasons may help make some of
those decisions clearer:
@itemize
@item
To gather all configuration details of a package into one place,
making it easier to copy, disable, or move it elsewhere in the init
file.
@item
To reduce duplication and boilerplate, capturing several common
practices as mere keywords both easy and intuitive to use.
@item
To make startup time of Emacs as quick as possible, without
sacrificing the quantity of add-on packages used.
@item
To make it so errors encountered during startup disable only the
package raising the error, and as little else as possible, leaving a
close to a functional Emacs as possible.
@item
To allow byte-compilation of one's init file so that any warnings or
errors seen are meaningful. In this way, even if byte-compilation is not
used for speed (reason 3), it can still be used as a sanity check.

@node @code{after}
@section @code{:after}
Sometimes it only makes sense to configure a package after another has been
loaded, because certain variables or functions are not in scope until that
time. This can achieved using an @code{:after} keyword that allows a fairly rich
description of the exact conditions when loading should occur. Here is an
example:
@lisp
(use-package hydra
:load-path "site-lisp/hydra")
(use-package ivy
:load-path "site-lisp/swiper")
(use-package ivy-hydra
:after (ivy hydra))
@end lisp
In this case, because all of these packages are demand-loaded in the order
they occur, the use of @code{:after} is not strictly necessary. By using it,
however, the above code becomes order-independent, without an implicit
depedence on the nature of your init file.
By default, @code{:after (foo bar)} is the same as @code{:after (:all foo bar)}, meaning
that loading of the given package will not happen until both @code{foo} and @code{bar}
have been loaded. Here are some of the other possibilities:
@lisp
:after (foo bar)
:after (:all foo bar)
:after (:any foo bar)
:after (:all (:any foo bar) (:any baz quux))
:after (:any (:all foo bar) (:all baz quux))
@end lisp
When you nest selectors, such as @code{(:any (:all foo bar) (:all baz quux))}, it
means that the package will be loaded when either both @code{foo} and @code{bar} have
been loaded, or both @code{baz} and @code{quux} have been loaded.
@strong{NOTE}: Pay attention if you set @code{use-package-always-defer} to t, and also use
the @code{:after} keyword, as you will need to specify how the declared package is
to be loaded: e.g., by some @code{:bind}. If you're not using one of the mechanisms
that registers autoloads, such as @code{:bind} or @code{:hook}, and your package manager
does not provide autoloads, it's possible that without adding @code{:demand t} to
those declarations, your package will never be loaded.
@node @code{bind-keymap} @code{bind-keymap*}
@section @code{:bind-keymap}, @code{:bind-keymap*}
Normally @code{:bind} expects that commands are functions that will be autoloaded
from the given package. However, this does not work if one of those commands
is actually a keymap, since keymaps are not functions, and cannot be
autoloaded using Emacs' @code{autoload} mechanism.
To handle this case, @code{use-package} offers a special, limited variant of
@code{:bind} called @code{:bind-keymap}. The only difference is that the "commands"
bound to by @code{:bind-keymap} must be keymaps defined in the package, rather than
command functions. This is handled behind the scenes by generating custom code
that loads the package containing the keymap, and then re-executes your
keypress after the first load, to reinterpret that keypress as a prefix key.
For example:
@lisp
(use-package projectile
:bind-keymap
("C-c p" . projectile-command-map)
@end lisp
@node @code{bind} @code{bind*}
@section @code{:bind}, @code{:bind*}
Another common thing to do when loading a module is to bind a key to primary
commands within that module:
@lisp
(use-package ace-jump-mode
:bind ("C-." . ace-jump-mode))
@end lisp
This does two things: first, it creates an autoload for the @code{ace-jump-mode}
command and defers loading of @code{ace-jump-mode} until you actually use it.
Second, it binds the key @code{C-.} to that command. After loading, you can use
@code{M-x describe-personal-keybindings} to see all such keybindings you've set
throughout your @code{.emacs} file.
A more literal way to do the exact same thing is:
@lisp
(use-package ace-jump-mode
:commands ace-jump-mode
:init
(bind-key "C-." 'ace-jump-mode))
@end lisp
When you use the @code{:commands} keyword, it creates autoloads for those commands
and defers loading of the module until they are used. Since the @code{:init} form
is always run---even if @code{ace-jump-mode} might not be on your system---remember
to restrict @code{:init} code to only what would succeed either way.
The @code{:bind} keyword takes either a cons or a list of conses:
@lisp
(use-package hi-lock
:bind (("M-o l" . highlight-lines-matching-regexp)
("M-o r" . highlight-regexp)
("M-o w" . highlight-phrase)))
@end lisp
The @code{:commands} keyword likewise takes either a symbol or a list of symbols.
NOTE: Special keys like @code{tab} or @code{F1}-@code{Fn} can be written in square brackets,
i.e. @code{[tab]} instead of @code{"tab"}. The syntax for the keybindings is similar to
the "kbd" syntax: see @uref{https://www.gnu.org/software/emacs/manual/html_node/emacs/Init-Rebinding.html, the Emacs Manual} for more information.
Examples:
@lisp
(use-package helm
:bind (("M-x" . helm-M-x)
("M-<f5>" . helm-find-files)
([f10] . helm-buffers-list)
([S-f10] . helm-recentf)))
@end lisp
@menu
* Binding to local keymaps::
@end menu
@node Binding to local keymaps
@subsection Binding to local keymaps
Slightly different from binding a key to a keymap, is binding a key @strong{within} a
local keymap that only exists after the package is loaded. @code{use-package}
supports this with a @code{:map} modifier, taking the local keymap to bind to:
@lisp
(use-package helm
:bind (:map helm-command-map
("C-c h" . helm-execute-persistent-action)))
@end lisp
The effect of this statement is to wait until @code{helm} has loaded, and then to
bind the key @code{C-c h} to @code{helm-execute-persistent-action} within Helm's local
keymap, @code{helm-mode-map}.
Multiple uses of @code{:map} may be specified. Any binding occurring before the
first use of @code{:map} are applied to the global keymap:
@lisp
(use-package term
:bind (("C-c t" . term)
:map term-mode-map
("M-p" . term-send-up)
("M-n" . term-send-down)
:map term-raw-map
("M-o" . other-window)
("M-p" . term-send-up)
("M-n" . term-send-down)))
@end lisp
@node @code{commands}
@section @code{:commands}
@node @code{preface} @code{init} @code{config}
@section @code{:preface}, @code{:init}, @code{:config}
Here is the simplest @code{use-package} declaration:
@lisp
;; This is only needed once, near the top of the file
(eval-when-compile
;; Following line is not needed if use-package.el is in ~/.emacs.d
(add-to-list 'load-path "<path where use-package is installed>")
(require 'use-package))
(use-package foo)
@end lisp
This loads in the package @code{foo}, but only if @code{foo} is available on your
system. If not, a warning is logged to the @code{*Messages*} buffer. If it
succeeds, a message about @code{"Loading foo"} is logged, along with the time it
took to load, if it took over 0.1 seconds.
Use the @code{:init} keyword to execute code before a package is loaded. It
accepts one or more forms, up until the next keyword:
@lisp
(use-package foo
:init
(setq foo-variable t))
@end lisp
Similarly, @code{:config} can be used to execute code after a package is loaded.
In cases where loading is done lazily (see more about autoloading below), this
execution is deferred until after the autoload occurs:
@lisp
(use-package foo
:init
(setq foo-variable t)
:config
(foo-mode 1))
@end lisp
As you might expect, you can use @code{:init} and @code{:config} together:
@lisp
(use-package color-moccur
:commands (isearch-moccur isearch-all)
:bind (("M-s O" . moccur)
:map isearch-mode-map
("M-o" . isearch-moccur)
("M-O" . isearch-moccur-all))
:init
(setq isearch-lazy-highlight t)
:config
(use-package moccur-edit))
@end lisp
In this case, I want to autoload the commands @code{isearch-moccur} and
@code{isearch-all} from @code{color-moccur.el}, and bind keys both at the global level
and within the @code{isearch-mode-map} (see next section). When the package is
actually loaded (by using one of these commands), @code{moccur-edit} is also
loaded, to allow editing of the @code{moccur} buffer.
@node @code{custom}
@section @code{:custom}
The @code{:custom} keyword allows customization of package custom variables.
@lisp
(use-package comint
:custom
(comint-buffer-maximum-size 20000 "Increase comint buffer size.")
(comint-prompt-read-only t "Make the prompt read only."))
@end lisp
The documentation string is not mandatory.
@node @code{custom-face}
@section @code{:custom-face}
The @code{:custom-face} keyword allows customization of package custom faces.
@lisp
(use-package eruby-mode
:custom-face
(eruby-standard-face ((t (:slant italic)))))
@end lisp
@node @code{defer} @code{demand}
@section @code{:defer}, @code{:demand}
In almost all cases you don't need to manually specify @code{:defer t}. This is
implied whenever @code{:bind} or @code{:mode} or @code{:interpreter} is used. Typically, you
only need to specify @code{:defer} if you know for a fact that some other package
will do something to cause your package to load at the appropriate time, and
thus you would like to defer loading even though use-package isn't creating
any autoloads for you.
You can override package deferral with the @code{:demand} keyword. Thus, even if
you use @code{:bind}, using @code{:demand} will force loading to occur immediately and
not establish an autoload for the bound key.
@node @code{defines} @code{functions}
@section @code{:defines}, @code{:functions}
Another feature of @code{use-package} is that it always loads every file that it
can when @code{.emacs} is being byte-compiled. This helps to silence spurious
warnings about unknown variables and functions.
However, there are times when this is just not enough. For those times, use
the @code{:defines} and @code{:functions} keywords to introduce dummy variable and
function declarations solely for the sake of the byte-compiler:
@lisp
(use-package texinfo
:defines texinfo-section-list
:commands texinfo-mode
:init
(add-to-list 'auto-mode-alist '("\\.texi$" . texinfo-mode)))
@end lisp
If you need to silence a missing function warning, you can use @code{:functions}:
@lisp
(use-package ruby-mode
:mode "\\.rb\\'"
:interpreter "ruby"
:functions inf-ruby-keys
:config
(defun my-ruby-mode-hook ()
(require 'inf-ruby)
(inf-ruby-keys))
(add-hook 'ruby-mode-hook 'my-ruby-mode-hook))
@end lisp
@node @code{diminish} @code{delight}
@section @code{:diminish}, @code{:delight}
@code{use-package} also provides built-in support for the diminish and delight
utilities---if you have them installed. Their purpose is to remove or change
minor mode strings in your mode-line.
@uref{https://github.com/myrjola/diminish.el, diminish} is invoked with the @code{:diminish} keyword, which is passed either a
minor mode symbol, a cons of the symbol and its replacement string, or just a
replacement string, in which case the minor mode symbol is guessed to be the
package name with "-mode" appended at the end:
@lisp
(use-package abbrev
:diminish abbrev-mode
:config
(if (file-exists-p abbrev-file-name)
(quietly-read-abbrev-file)))
@end lisp
@uref{https://elpa.gnu.org/packages/delight.html, delight} is invoked with the @code{:delight} keyword, which is passed a minor mode
symbol, a replacement string or quoted @uref{https://www.gnu.org/software/emacs/manual/html_node/elisp/Mode-Line-Data.html, mode-line data} (in which case the minor
mode symbol is guessed to be the package name with "-mode" appended at the
end), both of these, or several lists of both. If no arguments are provided,
the default mode name is hidden completely.
@lisp
;; Don't show anything for rainbow-mode.
(use-package rainbow-mode
:delight)
;; Don't show anything for auto-revert-mode, which doesn't match
;; its package name.
(use-package autorevert
:delight auto-revert-mode)
;; Remove the mode name for projectile-mode, but show the project name.
(use-package projectile
:delight '(:eval (concat " " (projectile-project-name))))
;; Completely hide visual-line-mode and change auto-fill-mode to " AF".
(use-package emacs
:delight
(auto-fill-function " AF")
(visual-line-mode))
@end lisp
@node @code{disabled}
@section @code{:disabled}
The @code{:disabled} keyword can turn off a module you're having difficulties with,
or stop loading something you're not using at the present time:
@lisp
(use-package ess-site
:disabled
:commands R)
@end lisp
When byte-compiling your @code{.emacs} file, disabled declarations are omitted
from the output entirely, to accelerate startup times.
@node @code{ensure} @code{pin}
@section @code{:ensure}, @code{:pin}
You can use @code{use-package} to load packages from ELPA with @code{package.el}. This
is particularly useful if you share your @code{.emacs} among several machines; the
relevant packages are downloaded automatically once declared in your @code{.emacs}.
The @code{:ensure} keyword causes the package(s) to be installed automatically if
not already present on your system (set @code{(setq use-package-always-ensure t)}
if you wish this behavior to be global for all packages):
@lisp
(use-package magit
:ensure t)
@end lisp
If you need to install a different package from the one named by
@code{use-package}, you can specify it like this:
@lisp
(use-package tex
:ensure auctex)
@end lisp
Lastly, when running on Emacs 24.4 or later, use-package can pin a package to
a specific archive, allowing you to mix and match packages from different
archives. The primary use-case for this is preferring packages from the
@code{melpa-stable} and @code{gnu} archives, but using specific packages from @code{melpa}
when you need to track newer versions than what is available in the @code{stable}
archives is also a valid use-case.
By default @code{package.el} prefers @code{melpa} over @code{melpa-stable} due to the
versioning @code{(> evil-20141208.623 evil-1.0.9)}, so even if you are tracking
only a single package from @code{melpa}, you will need to tag all the non-@code{melpa}
packages with the appropriate archive. If this really annoys you, then you can
set @code{use-package-always-pin} to set a default.
If you want to manually keep a package updated and ignore upstream updates,
you can pin it to @code{manual}, which as long as there is no repository by that
name, will Just Work(tm).
@code{use-package} throws an error if you try to pin a package to an archive that
has not been configured using @code{package-archives} (apart from the magic
@code{manual} archive mentioned above):
@example
Archive 'foo' requested for package 'bar' is not available.
@end example
Example:
@lisp
(use-package company
:ensure t
:pin melpa-stable)
(use-package evil
:ensure t)
;; no :pin needed, as package.el will choose the version in melpa
(use-package adaptive-wrap
:ensure t
;; as this package is available only in the gnu archive, this is
;; technically not needed, but it helps to highlight where it
;; comes from
:pin gnu)
(use-package org
:ensure t
;; ignore org-mode from upstream and use a manually installed version
:pin manual)
@end lisp
@strong{NOTE}: the @code{:pin} argument has no effect on emacs versions < 24.4.
@node @code{hook}
@section @code{:hook}
The @code{:hook} keyword allows adding functions onto hooks, here only the basename
of the hook is required. Thus, all of the following are equivalent:
@lisp
(use-package ace-jump-mode
:hook prog-mode)
(use-package ace-jump-mode
:hook (prog-mode . ace-jump-mode))
(use-package ace-jump-mode
:commands ace-jump-mode
:init
(add-hook 'prog-mode-hook #'ace-jump-mode))
@end lisp
And likewise, when multiple hooks should be applied, the following are also
equivalent:
@lisp
(use-package ace-jump-mode
:hook (prog-mode text-mode))
(use-package ace-jump-mode
:hook ((prog-mode text-mode) . ace-jump-mode))
(use-package ace-jump-mode
:hook ((prog-mode . ace-jump-mode)
(text-mode . ace-jump-mode)))
(use-package ace-jump-mode
:commands ace-jump-mode
:init
(add-hook 'prog-mode-hook #'ace-jump-mode)
(add-hook 'text-mode-hook #'ace-jump-mode))
@end lisp
The use of @code{:hook}, as with @code{:bind}, @code{:mode}, @code{:interpreter}, etc., causes the
functions being hooked to implicitly be read as @code{:commands} (meaning they will
establish interactive @code{autoload} definitions for that module, if not already
defined as functions), and so @code{:defer t} is also implied by @code{:hook}.
@node @code{if} @code{when} @code{unless}
@section @code{:if}, @code{:when}, @code{:unless}
You can use the @code{:if} keyword to predicate the loading and initialization of
modules.
For example, I only want @code{edit-server} running for my main, graphical Emacs,
not for other Emacsen I may start at the command line:
@lisp
(use-package edit-server
:if window-system
:init
(add-hook 'after-init-hook 'server-start t)
(add-hook 'after-init-hook 'edit-server-start t))
@end lisp
In another example, we can load things conditional on the operating system:
@lisp
(use-package exec-path-from-shell
:if (memq window-system '(mac ns))
:ensure t
:config
(exec-path-from-shell-initialize))
@end lisp
Note that @code{:when} is provided as an alias for @code{:if}, and @code{:unless foo} means
the same thing as @code{:if (not foo)}.
@node @code{load-path}
@section @code{:load-path}
If your package needs a directory added to the @code{load-path} in order to load,
use @code{:load-path}. This takes a symbol, a function, a string or a list of
strings. If the path is relative, it is expanded within
@code{user-emacs-directory}:
@lisp
(use-package ess-site
:load-path "site-lisp/ess/lisp/"
:commands R)
@end lisp
Note that when using a symbol or a function to provide a dynamically generated
list of paths, you must inform the byte-compiler of this definition so the
value is available at byte-compilation time. This is done by using the special
form @code{eval-and-compile} (as opposed to @code{eval-when-compile}). Further, this
value is fixed at whatever was determined during compilation, to avoid looking
up the same information again on each startup:
@lisp
(eval-and-compile
(defun ess-site-load-path ()
(shell-command "find ~ -path ess/lisp")))
(use-package ess-site
:load-path (lambda () (list (ess-site-load-path)))
:commands R)
@end lisp
@node @code{mode} @code{interpreter}
@section @code{:mode}, @code{:interpreter}
Similar to @code{:bind}, you can use @code{:mode} and @code{:interpreter} to establish a
deferred binding within the @code{auto-mode-alist} and @code{interpreter-mode-alist}
variables. The specifier to either keyword can be a cons cell, a list of cons
cells, or a string or regexp:
@lisp
(use-package ruby-mode
:mode "\\.rb\\'"
:interpreter "ruby")
;; The package is "python" but the mode is "python-mode":
(use-package python
:mode ("\\.py\\'" . python-mode)
:interpreter ("python" . python-mode))
@end lisp
If you aren't using @code{:commands}, @code{:bind}, @code{:bind*}, @code{:bind-keymap},
@code{:bind-keymap*}, @code{:mode}, or @code{:interpreter} (all of which imply @code{:defer}; see
the docstring for @code{use-package} for a brief description of each), you can
still defer loading with the @code{:defer} keyword:
@lisp
(use-package ace-jump-mode
:defer t
:init
(autoload 'ace-jump-mode "ace-jump-mode" nil t)
(bind-key "C-." 'ace-jump-mode))
@end lisp
This does exactly the same thing as the following:
@lisp
(use-package ace-jump-mode
:bind ("C-." . ace-jump-mode))
@end lisp
@node @code{magic} @code{magic-fallback}
@section @code{:magic}, @code{:magic-fallback}
Similar to @code{:mode} and @code{:interpreter}, you can also use @code{:magic} and
@code{:magic-fallback} to cause certain function to be run if the beginning of a
file matches a given regular expression. The difference between the two is
that @code{:magic-fallback} has a lower priority than @code{:mode}. For example:
@lisp
(use-package pdf-tools
:load-path "site-lisp/pdf-tools/lisp"
:magic ("%PDF" . pdf-view-mode)
:config
(pdf-tools-install))
@end lisp
This registers an autoloaded command for @code{pdf-view-mode}, defers loading of
@code{pdf-tools}, and runs @code{pdf-view-mode} if the beginning of a buffer matches the
string @code{"%PDF"}.
@node @code{no-require}
@section @code{:no-require}
Normally, @code{use-package} will load each package at compile time before
compiling the configuration, to ensure that any necessary symbols are in scope
to satisfy the byte-compiler. At times this can cause problems, since a
package may have special loading requirements, and all that you want to use
@code{use-package} for is to add a configuration to the @code{eval-after-load} hook. In
such cases, use the @code{:no-require} keyword:
@lisp
(use-package foo
:no-require t
:config
(message "This is evaluated when `foo' is loaded"))
@end lisp
@node @code{requires}
@section @code{:requires}
While the @code{:after} keyword delays loading until the dependencies are loaded,
the somewhat simpler @code{:requires} keyword simply never loads the package if the
dependencies are not available at the time the @code{use-package} declaration is
encountered. By "available" in this context it means that @code{foo} is available
of @code{(featurep 'foo)} evaluates to a non-nil value. For example:
@lisp
(use-package abbrev
:requires foo)
@end lisp
This is the same as:
@lisp
(use-package abbrev
:if (featurep 'foo))
@end lisp
As a convenience, a list of such packages may be specified:
@lisp
(use-package abbrev
:requires (foo bar baz))
@end lisp
For more complex logic, such as that supported by @code{:after}, simply use @code{:if}
and the appropriate Lisp expression.

# Changes
## 2.4.4
This release prepares for inclusion to GNU ELPA and includes no other changes
## 2.4.1
This is mostly a bug-fix release:
- Update the documentation for :custom as per #850
- Fix broken test due to #850
- better tests
- add test for #845
- Support keymap symbol in bind-key. Fix #845
- use-package-core.el: use the Emacs set-default function to avoid saving :custom vars twice
- Fix Travis
- typo, should be a vector, not a bytecode object
Solves https://github.com/jwiegley/use-package/issues/842
- Add special value back again, in case needed for backwards compat
I don't know why this special value exists, but perhaps old client code uses it.
The additional `t' in the macro expansion is accidental but not harmful I guess.
- Even when there's no :config, run any pre/post config hooks
i.e., following the existing docs for use-package-inject-hooks, these hooks are
run:
use-package--foo--pre-config-hook
use-package--foo--post-config-hook
This should make config customisations more predictable (for example, spacemacs
uses these hooks extensively to allow 'layers' to be customised).
I got rid of the "special" default value for :config, because it doesn't seem to
be treated any differently than nil.
Fixes #785
- Clarify the documentation for :after
- add table of contents to README
- Fix typos
Typos found with codespell.
- Fix typos
- Attempt to explain omit "-hook" better
- Update tests
- Switch from `require' to `load' + `featurep'
- Use `require', not `load', when byte-compiling
- Make custom-face evaluate elisp.
Fix #696.
- Add a line of documentation for (use-pacakage ... :hook).
- Fix typo in README
- Fix documentation for defer
- Add no-query option for pdf-tools-install
- Fix typo in README
- Fix all notes in README
- Mention use-package-ensure in README
Without requiring `use-package-ensure`, setting `use-package-always-ensure`
did not actually work for me.
## 2.4
### Breaking changes
- `use-package` no longer requires `diminish` as a dependency, allowing people
to decide whether they want to use diminish or delight. This means that if
you do use diminish, you'll now need to pull it into your configuration
before any use of the `:diminish` kewyord. For example:
``` elisp
(use-package diminish :ensure t)
```
- Emacs 24.3 or higher is now a requirement.
- The `:defer-install` keyword has been removed. It may reappear as an add-on
module for use-package in a future release. See issue #442 for more details.
- There is no longer a `use-package-debug` option, since `use-package-verbose`
already has the possible value of `debug`.
- The ordering of several elements of `use-package-keywords` have changed; if
you had previously customized this (or were an extension author adding to
this list), you may need to rework your changes.
- For extension authors, `:commands` should no longer be propagated down for
autoloading. See more below.
### Other changes
- Upgrade license to GPL 3.
- If `use-package-verbose` is set to the symbol `debug`, any evaluation errors
during package configuration will cause a complete report to be written to a
`*use-package*` buffer, including: the text of the error, the `use-package`
declaration that caused the error, the post-normalized form of this
declaration, and the macro-expanded version (without verbosity-related
code). Note that this still does not help if there are parsing errors, which
cause Emacs to register a Lisp error at startup time.
- New customization variable `use-package-deferring-keywords`, mainly intended
for use by extension packages, indicates keywords that, if used without
`:demand`, cause deferred loading (as if `:defer t` had been specified).
- The `:ensure` keyword now accepts a specific pinning sub-keyword. For
example:
``` elisp
(use-package foo
:pin "elpa")
```
This ensure the package `foo` is installed from `"elpa"`.
``` elisp
(use-package foo
:ensure bar
:ensure (quux :pin "melpa"))
```
This says that `foo` ensures that `bar` is installed, as well as `quux` from
`"melpa"`. It does *not* ensure that `foo` is installed, because explicit
`:ensure` keywords were given.
- New `:hook` keyword.
- New `:catch` keyword. If `t` or `nil`, it enables (the default, see
`use-package-defaults`) or disables catching errors at load time in
use-package expansions. It can also be a function taking two arguments: the
keyword being processed at the time the error was encountered, and the error
object (as generated by `condition-case`).
- New keywords `:custom (foo1 bar1) (foo2 bar2)` etc., and `:custom-face`.
NOTE: These are only for people who wish to keep customizations with their
accompanying use-package declarations. Functionally, the only benefit over
using `setq` in a `:config` block is that customizations might execute code
when values are assigned. If you currently use `M-x customize-option` and
save to a settings file, you do not want to use this option.
- New `:magic` and `:magic-fallback` keywords.
- New `:defer-install` keyword.
- New customization variable `use-package-enable-imenu-support`.
- New customization variable `use-package-hook-name-suffix`. Any symbols named
in `:hook`, or in the CAR of cons cells passed to `:hook`, have this text
appended to them as a convenience. If you find yourself using this keyword
to add to hooks of different names, or just don't want such appending done,
you can change the text to an empty string.
- New customization variable `use-package-compute-statistics`, and an
accompanying command `M-x use-package-report`. See the README for more
details.
- Allow `:diminish` to take no arguments.
- Support multiple symbols passed to `:after`, and a mini-DSL using `:all` and
`:any`.
- `:mode` and `:interpreter` can now accept `(rx ...)` forms.
- Using `:load-path` without also using `:ensure` now implies `:ensure nil`.
- `:bind (:map foo-map ...)` now defers binding in the map until the package
has been loaded.
- Print key bindings for keymaps in `describe-personal-keybindings`.
- When `use-package-inject-hooks` is non-nil, always fire `:init` and
`:config` hooks.
- Documentation added for the `:after`, `:defer-install`, `:delight`,
`:requires`, `:when` and `:unless` keywords.
- `:requires SYM` is subtly different from `:if (featurep SYM)`, in that it
happens before the `:preface`. This means that using `:requires` will cause
definitions in the `:preface` to not be visible to the byte-compiler,
leading to possible warnings about unknown functions, or functions that may
not be available at run-time (which can generally be ignored, since
`:requires` is intended as a check for basic system functionality; `:after`
should be used to check for the presence of other modules).
- New undocumented (and currently experimental) keyword `:load` may be used to
change the name of the actual package loaded, rather than the package name,
and may even add other names. For example: `(use-package auctex :load
tex-site)`. This keyword is used internally to generate the `require` for a
package, so that deferral is simply a matter of not generating this keyword.
- The source code is now broken into several files, so that certain optional
features (diminish, delight, ensure) may be maintained separately from the
core functionality.
- When using the `:after` keyword, now even autoloadeds keybinding are
deferred until after that other package has loaded, in order to allow
convenient `:bind` to maps only present in that other package. Consider the
following:
``` elisp
(use-package helm-descbinds
:load-path "site-lisp/helm-descbinds"
:after helm
:bind ("C-h b" . helm-descbinds)
:init
(fset 'describe-bindings 'helm-descbinds))
```
The binding of `C-h b` here will not occur until helm is loaded; and after
it is loaded, `helm-descbinds` itself is not loaded until the user presses
`C-h b`.
- For extension authors, if you add a keyword to `use-package-keywords` whose
presence should indicate deferred loading, please also add it to
`use-package-deferring-keywords`. Note that this is a bit of a sledgehammer,
in that the mere presence of these keywords implies deferred loading. For a
more subtle approach, see the new `use-package-autoloads/<KEYWORD>` support
mentioned in the next bullet.
- For extension authors, if you wish deferred loading to possibly occur,
create functions named `use-package-autoloads/<KEYWORD>` for each keyword
that you define, returning an alist of the form `(SYMBOL . TYPE)` of symbols
to be autoloaded. `SYMBOL` should be an interactive function, and `TYPE` the
smybol `command`, but this functionality may be extended in future. These
autoloads are established if deferred loading is to happen.
- If you specify a lambda form rather than a function symbol in any of the
constructs that *might* introduce autoloads: `:bind`, `:bind*`,
`:interpreter`, `:mode`, `:magic`, `:magic-fallback`, and `:hook`: then
deferred loading will no longer be implied, since there's nothing to
associate an autoload with that could later load the module. In these cases,
it will be as if you'd specified `:demand t`, in order to ensure the lambda
form is able to execute in the context of the loaded package.
- For extension authors, there is a new customization variable
`use-package-merge-key-alist` that specifies how values passed to multiple
occurrences of the same key should be merged into a single value, during
normalization of the `use-package` declaration into a proper plist. The
default behavior is to simply append the values together (since they are
always normalized to lists).
### Bug fixes
- Repeating a bind no longer causes duplicates in personal-keybindings.
- When byte-compiling, correctly output declare-function directives.
- Append to *use-package* when debugging, don't clear it.
- Don't allow :commands, :bind, etc., to be given an empty list.
- Explicit :defer t should override use-package-always-demand.

;;; Commentary:
;; If you have lots of keybindings set in your .emacs file, it can be hard to
;; know which ones you haven't set yet, and which may now be overriding some
;; new default in a new Emacs version. This module aims to solve that
;; problem.
;;
;; Bind keys as follows in your .emacs:
;;
;; (require 'bind-key)
;;
;; (bind-key "C-c x" 'my-ctrl-c-x-command)
;;
;; If the keybinding argument is a vector, it is passed straight to
;; `define-key', so remapping a key with `[remap COMMAND]' works as
;; expected:
;;
;; (bind-key [remap original-ctrl-c-x-command] 'my-ctrl-c-x-command)
;;
;; If you want the keybinding to override all minor modes that may also bind
;; the same key, use the `bind-key*' form:
;;
;; (bind-key* "<C-return>" 'other-window)
;;
;; If you want to rebind a key only in a particular keymap, use:
;;
;; (bind-key "C-c x" 'my-ctrl-c-x-command some-other-mode-map)
;;
;; To unbind a key within a keymap (for example, to stop your favorite major
;; mode from changing a binding that you don't want to override everywhere),
;; use `unbind-key':
;;
;; (unbind-key "C-c x" some-other-mode-map)
;;
;; To bind multiple keys at once, or set up a prefix map, a `bind-keys' macro
;; is provided. It accepts keyword arguments, please see its documentation
;; for a detailed description.
;;
;; To add keys into a specific map, use :map argument
;;
;; (bind-keys :map dired-mode-map
;; ("o" . dired-omit-mode)
;; ("a" . some-custom-dired-function))
;;
;; To set up a prefix map, use `:prefix-map' and `:prefix' arguments (both are
;; required)
;;
;; (bind-keys :prefix-map my-customize-prefix-map
;; :prefix "C-c c"
;; ("f" . customize-face)
;; ("v" . customize-variable))
;;
;; You can combine all the keywords together. Additionally,
;; `:prefix-docstring' can be specified to set documentation of created
;; `:prefix-map' variable.
;;
;; To bind multiple keys in a `bind-key*' way (to be sure that your bindings
;; will not be overridden by other modes), you may use `bind-keys*' macro:
;;
;; (bind-keys*
;; ("C-o" . other-window)
;; ("C-M-n" . forward-page)
;; ("C-M-p" . backward-page))
;;
;; After Emacs loads, you can see a summary of all your personal keybindings
;; currently in effect with this command:
;;
;; M-x describe-personal-keybindings
;;
;; This display will tell you if you've overridden a default keybinding, and
;; what the default was. Also, it will tell you if the key was rebound after
;; your binding it with `bind-key', and what it was rebound it to.

;; The `use-package' declaration macro allows you to isolate package

;; functionality!
