Update custom defaults.list

[Sergey "Shnatsel" Davidoff]

We should ship a custom defaults.list file so the file associations don't change with every new installed application (like it happens in Jupiter).

[Sergey "Shnatsel" Davidoff (shnatsel)]

In Oneiric, /usr/share/applications/defaults.list is a symlink to /usr/share/gnome/defaults.list; both files are shipped by desktop-file-utils package.

[Sergey "Shnatsel" Davidoff (shnatsel)]

XDG_DATA_DIRS controls the defaults.list to use; /etc/X11/Xsession.d/55gnome-session_gnomerc is the file that prepends /usr/share/gnome to its value. We probably should do the same.

[Sergey "Shnatsel" Davidoff (shnatsel)]

/etc/X11/Xsession.d/60-X11-common-xdg_path prepends new XDG dirs depending on the chosen section. If our session is called "pantheon", we can place customized things from /usr/share/gnome, as well as /usr/local/share/ and even /usr/share/ there.

[Sergey "Shnatsel" Davidoff (shnatsel)]

"there" means to /usr/share/pantheon, and that will be picked up in our session automagically.

[Mario Guerriero (mefrio-g)]

Sergey we can easily create our own defaults.list, put it in /usr/share/pantheon and then make a symlink with /usr/share/applications/defaults.list

[Sergey "Shnatsel" Davidoff (shnatsel)]

Mario, there's no need to symlink anything. Thanks to XDG_DATA_DIRS environment variable, contents of /etc/xdg/xdg-pantheon/ already override anything in /usr/share, so we can simply put the file there. That's how GNOME does it, too.

[Mario Guerriero (mefrio-g)]

So we only need to write a default.list and put it in /etc/xdg/xdg-pantheon?

[Sergey "Shnatsel" Davidoff (shnatsel)]

"defaults.list", not "default.list". Yes.

[Cody Garver (codygarver)]

I have attached a branch that contains a defaults.list to be further modified.

[Sergey "Shnatsel" Davidoff (shnatsel)]

I'm still unsure about two items: Shotwell which doesn't declare some mimes that it actually supports and rhythmbox-device.desktop to which we probably have no alternative so far; what's the status of Noise CLI interface btw?

[Sergey "Shnatsel" Davidoff (shnatsel)]

sorry, support of CLI parameters

[Sergey "Shnatsel" Davidoff (shnatsel)]

Man, Ubuntu is a mess. They have both rhythmbox-device.desktop and banshee-audiocd.desktop in defaults.list :/

[Sergey "Shnatsel" Davidoff (shnatsel)]

Sorry for misguiding you guys, /usr/share/pantheon is the correct location for session-specific overrides after all, not /etc/xdg/pantheon

[Sergey "Shnatsel" Davidoff (shnatsel)]

I've moved the file from a separate branch to pantheon-xsession-settings because it's easiest to apply such things session-specifically

[Sergey "Shnatsel" Davidoff (shnatsel)]

Mostly done, preliminary version deployed. We're waiting for some elementary apps to finalize CLI interfaces. Retargeting to beta2.

[Sergey "Shnatsel" Davidoff (shnatsel)]

I'll have to add/update "the text/calendar" entry as soon as bug 1080471 and bug 1091482 are fixed

[Cody Garver (codygarver)]

For Freya I did the following:

* Drop associations for apps we don't ship
* Associate text/xml with Scratch as seen in the Applications plug's Defaults code
* Replace Totem associations with Audience

Could not be bothered to inspect upstream's *buntu's various defaults, ours are complete enough for me.
