;; 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 by verifying the existence of
;; path "datadir/glib-2.0/schemas" in all input packages. If the path is
;; found in any package, then all programs in "out/bin" are wrapped in scripts
;; where the environment variable "XDG_DATA_DIRS" is set and points to the
;; list of found schemas directories.
;;
;; 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.
;;
;; Code:
(define %default-modules
;; Build-side modules made available in the build environment.
'((guix build glib-or-gtk-build-system)
(guix build utils)))
(define %default-imported-modules
