I've added bzr-explorer.desktop file based on olive-gtk.desktop for bzr-gtk, but it's really should be installed from deb package to proper location. Here is part of conversation with AfC about desktop files. I don't edit it yet, but there is some useful links.
[10:28] <AfC> bialix: the .desktop spec is fairly clear; what are you having trouble with?
[10:28] <bialix> AfC: Icon
[10:28] <bialix> I've hacked something based on olive-gtk.desktop and pushed to trunk
[10:28] <AfC> bialix: Should be just
[10:28] <bialix> anybody able to test?
[10:29] <AfC> Icon=/fully/qualified/path/to/file.png
[10:30] <bialix> AfC: hmm, because bzr-explorer it's a plugin then I dont think I know what will be /fully/qualified/path
[10:31] <AfC> I'd show you a working example, but judging by the discourteousness rudeness above, I think we'll skip that.
[10:32] * bialix wonder...
[10:32] <bialix> AfC: I don't quite understand what do you mean
[10:33] <AfC> bialix: that was a Gentoo user expressing that he doesn't quite appreciate other people rubbishing the hard work of people who contribute to community distros.
[10:34] <bialix> AfC: I'm Windows user/developer
[10:34] <bialix> AfC: and I'm native Russian
[10:35] <bialix> so if you think I say something wrong -- I'll live with that
[10:35] <AfC> bialix: it wasn't you. It was the others.
[10:35] <vila> AfC: ohhh, so sorry, that was a joke about me having lost the habit of installing linux the hard way,
[10:36] * bialix feels out of sync
[10:36] <AfC> bialix: but in this case, the working example I was going to show you was in a Gentoo package [to my knowledge it's not packaged in Debian or Ubuntu or Fedora]
[10:37] <bialix> I think I'd better skip all this stuff
[10:37] <AfC> bialix: but as the others here would just make fun of me if I attempted to show it, I think we'll just move on.
[10:37] <vila> Contrast my requirement to fullermd for an install: 'download iso, boot, click , click' and the way Gentoo is installed... different needs, different means, not a critic of the Gentoo community...

[10:41] <AfC> bialix: I do remember that http://standards.freedesktop.org/desktop-entry-spec/latest/apa.html was not much help, but http://standards.freedesktop.org/desktop-entry-spec/latest/ar01s02.html does give the rules
[10:42] <AfC> bialix: I believe the FHS path for .desktop files is /usr/share/applications
[10:42] <AfC> bialix: I have lots of .desktop files there.
[10:43] <AfC> bialix: if you're running Microsoft Windows (only) then that won't be of much help to you
[10:43] <bialix> AfC: so IIUC it should be done when packaging
[10:43] <AfC> bialix: yeah, that gets tricky
[10:43] <bialix> AfC: not only
[10:43] <bialix> AfC: but bzr development I do only there
[10:43] <AfC> bialix: it's one of those things that the program knows the data for, but that needs to get deployed by make install && packaging
[10:43] <bialix> AfC: Ok, thanks
[10:44] <bialix> I understand now
[10:44] <AfC> bialix: so what I can show you is a Perl script (a ./configure) that writes out a .desktop file at configure time.

[10:44] <AfC> bialix: see the very end of http://research.operationaldynamics.com/bzr/slashtime/mainline/configure
[10:44] <bialix> I think it will be toooo much for me
[10:45] <AfC> bialix: `make install` moves that to $(DESTDIR)$(PREFIX)/share/applications

[10:45] <AfC> s/that/the .desktop file that outputs/
[10:46] <bialix> I see
[10:46] <AfC> bialix: sorry I don't have a cleaner example; most projects do m4 macros or similar template substitution. I did it with Perl
[10:46] <bialix> np
[10:46] <bialix> I'm already understand I'm unable to propely do this stuff
[10:47] * bialix avoids do the things he can't test
[10:47] <AfC> bialix: and, for what it's worth, that IS an in-production application, so it is a real example
[10:47] <AfC> bialix: even if it's a very tiny program
[10:47] <bialix> tiny?
[10:47] <--| al-maisan has left #bzr ("Parting is tough..")
[10:48] <AfC> bialix: the package is just a small program that tells you the time[zone] in various places: http://blogs.operationaldynamics.com/andrew/software/slashtime/slashtime-the-graphical-version.html
[10:49] <bialix> I understand
[10:49] <AfC> "tiny" :)
[10:49] <bialix> :-)
[10:49] <AfC> but "complete" in the sense that it installs properly, has translations, has a .desktop file, etc
This is arguably part of bug 425507.
