Once @command{guix pull} has succeeded, the Guix REPL is restared. This
allows you to keep using the Emacs interface with the updated Guix.
Finally, there is an Emacs variant of @command{guix edit} command
(@pxref{Invoking guix edit}):
@table @kbd
@item M-x guix-edit
As with @kbd{M-x guix-packages-by-name}, you can press @key{TAB} to
complete a package name.
@end table
If you are contributing to Guix, you may find it useful for @kbd{M-x
guix-edit} to open package files from your git directory. This can be
done by setting @code{guix-directory} variable. For example, after
this:
@example
(setq guix-directory "~/src/guix")
@end example
@kbd{M-x guix-edit guix} opens
@file{~/src/guix/gnu/packages/package-management.scm} file.
Also you can use @kbd{C-u} prefix argument to specify a directory just
for the current @kbd{M-x guix-edit} command.

@node Emacs Package Locations
@section Package Source Locations
As you know, package definitions are placed in Guile files, also known
as @dfn{package locations}. The following commands should help you not
get lost in these locations:
@table @kbd
@item M-x guix-find-location
Open the given package definition source file (press @key{TAB} to choose
a location from a completion list).
@item M-x guix-edit
Find location of a specified package. This is an Emacs analog of
@command{guix edit} command (@pxref{Invoking guix edit}). As with
@kbd{M-x guix-packages-by-name}, you can press @key{TAB} to complete a
package name.
@end table
If you are contributing to Guix, you may find it useful for @kbd{M-x
guix-find-location} and @kbd{M-x guix-edit} to open locations from your
Git checkout. This can be done by setting @code{guix-directory}
variable. For example, after this:
@example
(setq guix-directory "~/src/guix")
@end example
@kbd{M-x guix-edit guix} opens
@file{~/src/guix/gnu/packages/package-management.scm} file.
Also you can use @kbd{C-u} prefix argument to specify a directory just
for the current @kbd{M-x guix-find-location} or @kbd{M-x guix-edit}
command.
