So many packages, so many source files! The
guix edit command
facilitates the life of users and packagers by pointing their editor at
the source file containing the definition of the specified packages.
guix edit firstname.lastname@example.org vim
launches the program specified in the
VISUAL or in the
EDITOR environment variable to view the recipe of GCC 4.9.3
and that of Vim.
If you are using a Guix Git checkout (see Building from Git), or
have created your own packages on
(see Package Modules), you will be able to edit the package
recipes. In other cases, you will be able to examine the read-only recipes
for packages currently in the store.
GUIX_PACKAGE_PATH, the command-line option
--load-path=directory (or in short -L
directory) allows you to add directory to the front of the
package module search path and so make your own packages visible.
