Until now users would have to cargo cult or inspect the private
%default-modules variable of (guix build-systems gnu) to discover which
modules to include when extending the used modules via the #:modules argument.
The renaming was automated via the command:
$ git grep -l %gnu-build-system-modules
| xargs sed 's/%gnu-build-system-modules/%default-gnu-imported-modules/' -i
* guix/build-system/gnu.scm (%gnu-build-system-modules): Rename to...
(%default-gnu-imported-modules): ... this.
(%default-modules): Rename to...
(%default-gnu-modules): ... this. Export.
(dist-package, gnu-build, gnu-cross-build): Adjust accordingly.

;; Commentary:
|
|
;;
|
|
;; This build system is an extension of the 'gnu-build-system'. It
|
|
;; accomodates the needs of applications making use of glib or gtk+ (with "or"
|
|
;; to be interpreted in the mathematical sense). This is achieved by adding
|
|
;; two phases run after the 'install' phase:
|
|
;;
|
|
;; 'glib-or-gtk-wrap' phase:
|
|
;;
|
|
;; a) This phase looks for GSettings schemas, GIO modules and theming data.
|
|
;; If any of these is found in any input package, then all programs in
|
|
;; "out/bin" are wrapped in scripts defining the nedessary environment
|
|
;; variables.
|
|
;;
|
|
;; b) Looks for the existence of "libdir/gtk-3.0" directories in all input
|
|
;; packages. If any is found, then the environment variable "GTK_PATH" is
|
|
;; suitably set and added to the wrappers. The variable "GTK_PATH" has been
|
|
;; preferred over "GTK_EXE_PREFIX" because the latter can only point to a
|
|
;; single directory, while we may need to point to several ones.
|
|
;;
|
|
;; 'glib-or-gtk-compile-schemas' phase:
|
|
;;
|
|
;; Looks for the presence of "out/share/glib-2.0/schemas". If that directory
|
|
;; exists and does not include a file named "gschemas.compiled", then
|
|
;; "glib-compile-schemas" is run in that directory.
