Improve gsettings support

[Marc-Antoine Perennou]

Hi,

Currently, intltool's support for gsettings is restricted to *.gschema.xml files.
It would be great to also support *.gschema.xml(.in)* files (like it already supports *.xml.in, *.desktop.in.in files and so on)

This would allow to make some substitutions in the gschema files, which is currently not supported since substitued stuff goes in builddir and only things in srcdir are allowed in POTFILES.

This patch solves this issue here

Hi Marc-Antoine, thanks for the patch and bug report.

What kind of substitutions do you plan to make in these files? I am just wondering to see if this really makes sense to support .in files as well.

[Marc-Antoine Perennou (keruspe)]

Hi,

Actually, like most of the projects using gsettings, I'm providing a .in file in which the Gettext package gets substituted.

I don't think I've ever seen any project doing differently

Please don't add this support. Using .in with a nomerge rule for GSettings schemas was only ever done because intltool was lacking proper native support. There is no reason for doing this anymore.
