This patch lets GLib's GDesktopAppInfo API watch and notice changes
|
|
to the Guix user and system profiles. That way, the list of available
|
|
applications shown by the desktop environment is immediately updated
|
|
when the user runs "guix install", "guix remove", or "guix system
|
|
reconfigure" (see <https://issues.guix.gnu.org/35594>).
|
|
|
|
It does so by monitoring /var/guix/profiles (for changes to the system
|
|
profile) and /var/guix/profiles/per-user/USER (for changes to the user
|
|
profile) and crawling their share/applications sub-directory when
|
|
changes happen.
