|
|
GNU Guix comes with a visual user interface for GNU@tie{}Emacs, known
|
|
as ``guix.el''. It can be used for routine package management tasks,
|
|
pretty much like the @command{guix package} command (@pxref{Invoking
|
|
guix package}). Specifically, ``guix.el'' makes it easy to:
|
|
|
|
@itemize
|
|
@item browse and display packages and generations;
|
|
@item search, install, upgrade and remove packages;
|
|
@item display packages from previous generations;
|
|
@item do some other useful things.
|
|
@end itemize
|
|
|
|
@menu
|
|
* Initial Setup: emacs Initial Setup. Preparing @file{~/.emacs}.
|
|
* Usage: emacs Usage. Using the interface.
|
|
* Configuration: emacs Configuration. Configuring the interface.
|
|
@end menu
|
|
|
|
@node emacs Initial Setup
|
|
@subsection Initial Setup
|
|
|
|
To be able to use ``guix.el'', you need to install the following
|
|
packages:
|
|
|
|
@itemize
|
|
@item
|
|
@uref{http://www.gnu.org/software/emacs/, GNU Emacs}, version 24.3 or
|
|
later;
|
|
|
|
@item
|
|
@uref{http://nongnu.org/geiser/, Geiser}, version 0.3 or later: it is
|
|
used for interacting with the Guile process.
|
|
|
|
@end itemize
|
|
|
|
When it is done, add the following into your init file (@pxref{Init
|
|
File,,, emacs, The Emacs Editor}):
|
|
|
|
@example
|
|
(require 'guix-init nil t)
|
|
@end example
|
|
|
|
However there is a chance that @code{load-path} of your Emacs does not
|
|
contain a directory with ``guix.el'' (usually it is
|
|
@file{/usr/share/emacs/site-lisp/}). In that case you need to add it
|
|
before requiring (@pxref{Lisp Libraries,,, emacs, The Emacs Editor}):
|
|
|
|
@example
|
|
(add-to-list 'load-path "/path/to/directory-with-guix.el")
|
|
(require 'guix-init)
|
|
@end example
|
|
|
|
Do not worry about the efficiency of that @code{require} thing. It will
|
|
not load the whole ``guix.el'' package, it will just autoload the main
|
|
interactive commands (@pxref{Autoload,,, elisp, Emacs Lisp}).
|
|
|
|
|
|
@node emacs Usage
|
|
@subsection Usage
|
|
|
|
Once ``guix.el'' has been successfully configured, you should be able to
|
|
use commands for displaying packages and generations. This information
|
|
can be displayed in a ``list'' or ``info'' buffer.
|
|
|
|
@menu
|
|
* Commands: emacs Commands. @kbd{M-x guix-@dots{}}
|
|
* General information: emacs General info. Common for both interfaces.
|
|
* ``List'' buffer: emacs List buffer. List-like interface.
|
|
* ``Info'' buffer: emacs Info buffer. Help-like interface.
|
|
@end menu
|
|
|
|
@node emacs Commands
|
|
@subsubsection Commands
|
|
|
|
You may use the following commands to display packages and generations:
|
|
|
|
@table @kbd
|
|
@item M-x guix-all-available-packages
|
|
@itemx M-x guix-newest-available-packages
|
|
Display all/newest available packages.
|
|
|
|
@item M-x guix-installed-packages
|
|
Display all packages installed in the current profile.
|
|
|
|
@item M-x guix-obsolete-packages
|
|
Display obsolete packages (the packages that are installed in the
|
|
current profile but cannot be found among available packages).
|
|
|
|
@item M-x guix-search-by-name
|
|
Display package(s) with the specified name.
|
|
|
|
@item M-x guix-search-by-regexp
|
|
Search for packages by a specified regexp. By default ``name'',
|
|
``synopsis'' and ``description'' of the packages will be searched. This
|
|
can be changed by modifying @code{guix-search-params} variable.
|
|
|
|
@item M-x guix-generations
|
|
List generations for the current profile. With numeric prefix, show so
|
|
many last generations.
|
|
|
|
@end table
|
|
|
|
By default commands for displaying packages display each output on a
|
|
separate line. If you prefer to see a list of packages---i.e., a list
|
|
with a package per line, use the following setting:
|
|
|
|
@example
|
|
(setq guix-package-list-type 'package)
|
|
@end example
|
|
|
|
It is possible to change the currently used profile with
|
|
@kbd{M-x@tie{}guix-set-current-profile}. This has the same effect as
|
|
specifying @code{--profile} option for @command{guix package}
|
|
(@pxref{Invoking guix package}).
|
|
|
|
@node emacs General info
|
|
@subsubsection General information
|
|
|
|
The following keys are available for both ``list'' and ``info'' types of
|
|
buffers:
|
|
|
|
@table @kbd
|
|
@item l
|
|
@itemx r
|
|
Go backward/forward by the history of the displayed results (this
|
|
history is similar to the history of the Emacs @code{help-mode} or
|
|
@code{Info-mode}).
|
|
|
|
@item g
|
|
Revert current buffer: update information about the displayed
|
|
packages/generations and redisplay it.
|
|
|
|
@item R
|
|
Redisplay current buffer (without updating information).
|
|
|
|
@item C-c C-z
|
|
Go to the Guix REPL (@pxref{The REPL,,, geiser, Geiser User Manual}).
|
|
|
|
@item h
|
|
@itemx ?
|
|
Describe current mode to see all available bindings.
|
|
|
|
@end table
|
|
|
|
@emph{Hint:} If you need several ``list'' or ``info'' buffers, you can
|
|
simlpy @kbd{M-x clone-buffer} them, and each buffer will have its own
|
|
history.
|
|
|
|
@emph{Warning:} Name/version pairs cannot be used to identify packages
|
|
(because a name is not necessarily unique), so ``guix.el'' uses special
|
|
identifiers that live only during a guile session, so if the Guix REPL
|
|
was restarted, you may want to revert ``list'' buffer (by pressing
|
|
@kbd{g}).
|
|
|
|
@node emacs List buffer
|
|
@subsubsection ``List'' buffer
|
|
|
|
An interface of a ``list'' buffer is similar to the interface provided
|
|
by ``package.el'' (@pxref{Package Menu,,, emacs, The Emacs Editor}).
|
|
|
|
Default key bindings available for both ``package-list'' and
|
|
``generation-list'' buffers:
|
|
|
|
@table @kbd
|
|
@item m
|
|
Mark the current entry.
|
|
@item M
|
|
Mark all entries.
|
|
@item u
|
|
Unmark the current entry (with prefix, unmark all entries).
|
|
@item @key{DEL}
|
|
Unmark backward.
|
|
@item S
|
|
Sort entries by a specified column.
|
|
@end table
|
|
|
|
A ``package-list'' buffer additionally provides the following bindings:
|
|
|
|
@table @kbd
|
|
@item @key{RET}
|
|
Describe marked packages (display available information in a
|
|
``package-info'' buffer).
|
|
@item i
|
|
Mark the current package for installation.
|
|
@item d
|
|
Mark the current package for deletion.
|
|
@item U
|
|
Mark the current package for upgrading.
|
|
@item ^
|
|
Mark all obsolete packages for upgrading.
|
|
@item x
|
|
Execute actions on the marked packages.
|
|
@end table
|
|
|
|
A ``generation-list'' buffer additionally provides the following
|
|
bindings:
|
|
|
|
@table @kbd
|
|
@item @key{RET}
|
|
List packages installed in the current generation.
|
|
@item i
|
|
Describe marked generations (display available information in a
|
|
``generation-info'' buffer).
|
|
@item d
|
|
Mark the current generation for deletion (with prefix, mark all
|
|
generations).
|
|
@item x
|
|
Execute actions on the marked generations---i.e., delete generations.
|
|
@end table
|
|
|
|
@node emacs Info buffer
|
|
@subsubsection ``Info'' buffer
|
|
|
|
The interface of an ``info'' buffer is similar to the interface of
|
|
@code{help-mode} (@pxref{Help Mode,,, emacs, The Emacs Editor}).
|
|
|
|
``Info'' buffer contains some buttons (as usual you may use @key{TAB} /
|
|
@kbd{S-@key{TAB}} to move between buttons---@pxref{Mouse References,,,
|
|
emacs, The Emacs Editor}) which can be used to:
|
|
|
|
@itemize @bullet
|
|
@item (in a ``package-info'' buffer)
|
|
|
|
@itemize @minus
|
|
@item install/remove a package;
|
|
@item jump to a package location;
|
|
@item browse home page of a package;
|
|
@item describe packages from ``Inputs'' fields.
|
|
@end itemize
|
|
|
|
@item (in a ``generation-info'' buffer)
|
|
|
|
@itemize @minus
|
|
@item remove a generation;
|
|
@item list packages installed in a generation;
|
|
@item jump to a generation directory.
|
|
@end itemize
|
|
|
|
@end itemize
|
|

@node emacs Configuration
|
|
@subsection Configuration
|
|
|
|
There are many variables you can modify to change the appearance or
|
|
behavior of Emacs user interface. Some of these variables are described
|
|
in this section. Also you can use Custom Interface (@pxref{Easy
|
|
Customization,,, emacs, The Emacs Editor}) to explore/set variables (not
|
|
all) and faces.

If you have some special needs for starting a Guile process, you may set
|
|
this variable, for example:
|
|
|
|
@example
|
|
(setq guix-guile-program '("/bin/guile" "--no-auto-compile"))
|
|
@end example
|
|
|

@node emacs Buffer Names
|
|
@subsubsection Buffer Names
|
|
|
|
Default names of ``guix.el'' buffers (``*Guix@tie{}@dots{}*'') may be
|
|
changed with the following variables:
|
|
|
|
@table @code
|
|
@item guix-package-list-buffer-name
|
|
@item guix-output-list-buffer-name

|
@item guix-repl-buffer-name
|
|
@item guix-internal-repl-buffer-name
|
|
@item guix-temp-buffer-name
|
|
@end table
|
|
|
|
For example if you want to display all types of results in a single
|
|
buffer (in such case you will probably use a history (@kbd{l}/@kbd{r})
|
|
extensively), you may do it like this:
|
|
|
|
@example
|
|
(let ((name "Guix Universal"))
|
|
(setq
|
|
guix-package-list-buffer-name name
|

guix-output-list-buffer-name name
|
|
guix-generation-list-buffer-name name
|
|
guix-package-info-buffer-name name
