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. For
guix edit firstname.lastname@example.org vim
launches the program specified in the
VISUAL or in the
environment variable to view the recipe of GCC 4.9.3 and that of Vim.
If you are using a Guix Git checkout (see 从Git构建), or have
created your own packages on
GUIX_PACKAGE_PATH (see 软件包模块), 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
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.
