Hi!

Looking into this source file I found out that it would make it
possible to support Gtk+ themes out of the box, if the environment
variable GTK_DATA_PREFIX is set to the base directory of the user's
profile (e.g. /home/rms/.guix_profile/). I tried it with lxapearance
and it seems to work. The problem Mark mentioned on IRC is that this
can't contain multiple directories. But looking at the sources (e.g.
https://git.gnome.org/browse/gtk+/tree/gtk/gtkcssprovider.c, line 2071)
this seems to be the only opportunity to set this. Any ideas? Maybe
there's a better option, I don't know.

Fabian

It does seem to be the only environment variable to allow for a
different location for themes.  It also doesn’t seem to negatively
affect anything else.  (‘_gtk_get_data_prefix ()’ still returns the
compile-time prefix and is used to find ‘settings.ini’.)

GTK_DATA_PREFIX is not a search path, so it’s expected that only one
directory can be specified.  Is this a problem?

I don't know, I've sent a patch adding it to the /etc/profile file, as
Mark (Weaver) suggested first. But this affects only the user profile
and not the system profile, so far I understand it. But for example the
GStreamer plugins path environment variable is also defined there.

While I've understood the main aspects and principals of Guix as a
package manager, that's not the case for the services and the system
distribution. The reason might be (and is) that I'm not running it for
now.

Fabian.
