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 + ;; Build-side modules imported and used by default. + '((guix build gnu-build-system) + (guix build glib-or-gtk-build-system) + (guix build utils))) + +(define (default-glib) + "Return the default glib package from which we use +\"glib-compile-schemas\"." + ;; Do not use `@' to avoid introducing circular dependencies. + (let ((module (resolve-interface '(gnu packages glib)))) + (module-ref module 'glib))) + +(define* (lower name + #:key source inputs native-inputs outputs system target + (glib (default-glib)) (implicit-inputs? #t) + (strip-binaries? #t) + #:allow-other-keys + #:rest arguments) + "Return a bag for NAME." + (define private-keywords + '(#:source #:target #:glib #:inputs #:native-inputs + #:outputs #:implicit-inputs?)) + + (and (not target) ;XXX: no cross-compilation + (bag + (name name) + (system system) + (host-inputs `(,@(if source + `(("source" ,source)) + '()) + ,@inputs)) + (build-inputs `(("glib:bin" ,glib) + ,@(if implicit-inputs? + (standard-packages) + '()) + ,@native-inputs)) + (outputs outputs) + (build glib-or-gtk-build) + (arguments (strip-keyword-arguments private-keywords arguments))))) + +(define* (glib-or-gtk-build store name inputs + #:key (guile #f) + (outputs '("out")) + (search-paths '()) + (configure-flags ''()) + (make-flags ''()) + (out-of-source? #t) + (tests? #t) + (test-target "check") + (parallel-build? #t) + (parallel-tests? #t) + (patch-shebangs? #t) + (strip-binaries? #t) + (strip-flags ''("--strip-debug")) + (strip-directories ''("lib" "lib64" "libexec" + "bin" "sbin")) + (phases '(@ (guix build glib-or-gtk-build-system) + %standard-phases)) + (system (%current-system)) + (imported-modules %default-imported-modules) + (modules %default-modules) + allowed-references) + "Build SOURCE with INPUTS.
