which processes desktop files anyway, and allow defaults.list with (XDG)

Maybe reuse XDG_MENU_PREFIX for this?
(also, make sure the file lives in /etc/xdg, maybe /etc/xdg/mime?)

Yes, for defaults.list it is a definitely a good idea. For defaults.conf
or so it may be possible as well, but update-desktop-database then has
to scan for all of them.

I am not sure, whether there are benefits of a directory that contains
parts of defaults.conf - e. g. defaults.conf.d.

[Desktop Defaults]
# ... maybe something will be here as well

# These applications should be default for all MIME types they support.
# This application is preferred over Default applications for all MIME
types they support.
# but moonshine should be default for listed MIME types

Not a big fan of this syntax. I would prefer the reverse one, but:

well, reverse syntax may be better, who knows

video/x-ms-asf-plugin is not a valid key in such files: '/' cannot be
used there. We can replace the '/' with a '-', though, and the first '-'
will always be translated ti a '/'.

Well, the first one may result a smaller config file. But the second is
more readable. And it makes easy to check, that no MIME type is used

# You may want to remove applications you inherit

Hrm, do we need this? I don't see the gain here.

# Or ignore some applications and never use them as default

Is this really useful? (and what's the difference with Remove?)

It was just an idea:


Suppose you want to create a new session type MyGNOME. It should inherit
on GNOME, but banshee should not be preferred there. If there is no
other application for a particular MIME type, banshee may be still
assigned as default.



Define a new session type, where banshee is never set in defaults.list:

# If there is no application listed above, prefer application with these

Is this a list? If yes, it should be "GNOME;". What happens if you have
more than one category there? Is this a "AND" or "OR" of those

Well, not sure. It may be a list, and it may be just a single key and
force virtual Inherit, if you need more keys.

Allowing a list is probably a good idea. Inherited categories would be
evaluated after the last item of the list.

AND probably does not make sense. OR would be better. First wins may be
a good rule that would allow definitions like:

Maybe name it PreferCategories?

Yes, it is possible. I just used key from desktop files.

# And if everything fail, try inherited class
