Attached are some unfinished patches that illustrate this idea; notes
- flags are replaced by textual strings (notice the resemblance to mime
types?)
- content sniffing happens in a thread when done async
- no actual sniffing is done; should be trivial to add though
- needs work in the drive classification bits.
- There's some other stuff I wanted to propose regardless of this
- get_id() on GDrive,Volume,Mount: needed to pass these around
- model,vendor on GDrive; some apps (notably the cd burner ones) will
need this for user selection when having multiple drives
Anyway, with this patch it should be simple to abuse the .desktop file
format and add something x-content/video to e.g. Totem's and mplayer's
desktop files. Then we can easily add machinery to the Preferred
Applications capplet for choosing the default video player and we can
finally get rid of this ugly entry boxes
http://people.freedesktop.org/~david/g-v-m-prefs.png
Ditto for the other x-content/* formats. This is a problem we haven't
been able to solve for three years...
If you like this idea, here are the next steps I'm going to do
- Finish the patch
- Propose x-content/* and x-drive/* types as a fd.o spec on xdg-list
- Make the directory sniffing code plug-in based
(I expect we want to update this code rather frequently, it's a
bit like shared-mime-info)
Anyway, the whole idea may be crack (I don't think so though), but you
can't accuse me of not thinking in a "user document" centric way with
this :-)
