If you install Guix in your user profile, -this auto-loading is done automatically by our Emacs package -(@pxref{Application Setup}), so a universal recipe for configuring -``guix.el'' is: @command{guix package -i guix}. If you do this, there -is no need to read further. - -For the manual installation, you need to add the following code into -your init file (@pxref{Init File,,, emacs, The GNU Emacs Manual}): - -@example -(add-to-list 'load-path "/path/to/directory-with-guix.el") -(require 'guix-autoloads nil t) -@end example - -So the only thing you need to figure out is where the directory with -elisp files for Guix is placed.

It is faster than running -@code{guix@tie{}@dots{}} command directly in shell, as there is no -need to run another guile process and to load required modules there. - -@item -Run the command in a shell buffer. You can set -@code{guix-run-in-shell-function} variable to fine tune the shell buffer -you want to use. - -@item -Add the command line to the kill ring (@pxref{Kill Ring,,, emacs, The -GNU Emacs Manual}). - -@end itemize - -Several commands (@command{guix graph}, @command{guix system shepherd-graph} -and @command{guix system extension-graph}) also have a ``View graph'' -action, which allows you to view a generated graph using @command{dot} -command (specified by @code{guix-dot-program} variable). By default a -PNG file will be saved in @file{/tmp} directory and will be opened -directly in Emacs. This behavior may be changed with the following -variables: - -@table @code - -@item guix-find-file-function -Function used to open a generated graph. If you want to open a graph in -an external program, you can do it by modifying this variable---for -example, you can use a functionality provided by the Org Mode -(@pxref{Top,,, org, The Org Manual}): - -@example -(setq guix-find-file-function 'org-open-file) -(add-to-list 'org-file-apps '("\\.png\\'" .

If you modified the -current package definition, don't forget to reevaluate it before calling -this command---for example, with @kbd{C-M-x} (@pxref{To eval or not to -eval,,, geiser, Geiser User Manual}) -(@code{guix-devel-build-package-definition}). - -@item C-c . s -Build a source derivation of the package defined by the current variable -definition. This command has the same meaning as @code{guix build -S} -shell command (@pxref{Invoking guix build}) -(@code{guix-devel-build-package-source}). - -@item C-c . l -Lint (check) a package defined by the current variable definition -(@pxref{Invoking guix lint}) (@code{guix-devel-lint-package}). - -@end table - -Unluckily, there is a limitation related to long-running REPL commands. -When there is a running process in a Geiser REPL, you are not supposed -to evaluate anything in a scheme buffer, because this will ``freeze'' -the REPL: it will stop producing any output (however, the evaluating -process will continue---you will just not see any progress anymore). Be -aware: even moving the point in a scheme buffer may ``break'' the REPL -if Autodoc (@pxref{Autodoc and friends,,, geiser, Geiser User Manual}) -is enabled (which is the default). - -So you have to postpone editing your scheme buffers until the running -evaluation will be finished in the REPL. - -Alternatively, to avoid this limitation, you may just run another Geiser -REPL, and while something is being evaluated in the previous REPL, you -can continue editing a scheme file with the help of the current one. - - -@node Emacs Hydra -@section Hydra - -The continuous integration server at @code{hydra.gnu.org} builds all -the distribution packages on the supported architectures and serves -them as substitutes (@pxref{Substitutes}). Continuous integration is -currently orchestrated by @uref{https://nixos.org/hydra/, Hydra}. - -This section describes an Emacs interface to query Hydra to know the -build status of specific packages, discover recent and ongoing builds, -view build logs, and so on. This interface is mostly the same as the -``list''/``info'' interface for displaying packages and generations -(@pxref{Emacs Package Management}). - -The following commands are available: - -@table @kbd - -@item M-x guix-hydra-latest-builds -Display latest failed or successful builds (you will be prompted for a -number of builds). With @kbd{C-u}, you will also be prompted for other -parameters (project, jobset, job and system). - -@item M-x guix-hydra-queued-builds -Display scheduled or currently running builds (you will be prompted for -a number of builds). - -@item M-x guix-hydra-jobsets -Display available jobsets (you will be prompted for a project). - -@end table - -In a list of builds you can press @kbd{L} key to display a build log of -the current build. Also both a list of builds and a list of jobsets -provide @kbd{B} key to display latest builds of the current job or -jobset (don't forget about @kbd{C-u}). |
