Very, very strongly agreed with all this for exactly the reasons you highlighted. > > We'd also like to tell people that applications putting data in > ~/.config/ are expected to use the D-Bus style naming scheme to select a > directory for themselves.

Agreed in general but I'm not sure if entirely dropping the legacy definition of ~/.local/share is wise. As long as actual configuration is stored in ~/.config, and actual cache is stored in ~/.cache, I have no problem with applications using ~/.local/share as their everything-else-dump. Looking at what's in my /usr/share right now ... it does act as a systemwide "I didn't know where else to put this" dump. Maybe we can rename the variable to $XDG_TOSS_IT_WHERE_THERE_IS_ROOM_DIRS. But yes, agreed with the general idea. Are you moving towards requiring dbus-style naming? I'm ok with encouraging it, but not ok with requiring it. Of course, if two apps conflict, they should move (both of them, and having to handle migration becomes their own fault for not following the recommendation). > > The main thrust behind this conclusion is that we've had a lot of people > from a wide range of areas (everyone from game developers to Firefox) > telling us that the current split of "config" vs. "data" is very > difficult for them to support and not something that they have on other > platforms.

This is also the feedback I hear from a lot of people. It's also kinda what they already do, so the cat is already out of that bag. People use ~/.config for everything and the apps that don't follow xdg have a single unsplittable directory. Being able to tell them "go ahead and just move it to ~/.config" is a lot easier. > > A couple of caveats: > > 1) I mention "plugins" above while talking about "share".

It was in ~/.Trash at some point, wasn't it? In hindsight, it was just fine there and it probably shouldn't have been moved, but it's not really problematic in ~/.local/share either. > > Cheers > _______________________________________________ > xdg mailing list > xdg@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/xdg _______________________________________________ xdg mailing list xdg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xdg
