I would expect that freedesktop.org's solution is intended to avoid just that -- having to patch or contribute to dozens of desktop environments, toolkits and who-knows-how-many desktop programs that all want to write something in user's directory just to give different defaults. What I mean by that is, I expect that the distributions/desktop environments can just set XDG_* variables, and a large amount of toolkits and programs simply adhere to this directive. I suggest that this is a reasonably sane behavior to adopt for GNUstep as well: a default (or at least additional, easily adoptable) layout config which uses the XDG_* variables, and defaults to something reasonably universal (such as defaulting to ~/.config in case XDG_CONFIG_HOME is not set). Of course, the current default has been the default for long enough that we may want to still implement a fall-back to reading from the location that is currently shipped in the default layout config. - ~/GNUstep can still be a decent location for everything not specified in basedir-spec. For example, ~/GNUstep/Applications mentioned somewhere in the thread is a good candidate for applications installed into user domain. - XDG_CONFIG_HOME seems to map decently to GNUSTEP_USER_DEFAULTS_DIR in layout. - XDG_DATA_HOME seems to map decently to the NSApplicationSupportDirectory in user domain; this doesn't seem to be listed in the layout config file - Directories listed in XDG_DATA_DIRS seem to map decently to directories in NSApplicationSupportDirectory's system domain, unless they explicitly live in user's home folder. - XDG_CACHE_HOME seems to map decently to NSCachesDirectory in user domain; this also doesn't seem to be listed in the layout config file. - XDG_RUNTIME_DIR "defines the base directory relative to which user-specific non-essential runtime files and other file", and also seems potentially useful; I assume this is a way to specify a per-user /tmp equivalent (possibly living under /tmp). - apparently in a separate spec there is XDG_DOWNLOAD_DIR <http://0pointer.de/blog/projects/tmp.html> (also see here <http://freedesktop.org/wiki/Software/xdg-user-dirs/>) which should be used for downloads and downloads in progress -- that is, it seems to define NSDownloadsDirectory and default to ~/Downloads. It doesn't seem to be an environment variable; it seems specified in a file. - that <http://freedesktop.org/wiki/Software/xdg-user-dirs/> link also mentions XDG_DESKTOP_DIR -- without digging deeper, I would expect that the actual list of directories obtainable through XDG_* variables is even bigger If various desktop environments and toolkits make use of these variables and config files, why wouldn't GNUstep applications? GNUstep doesn't even currently have its own full desktop; if it did, it might sort-of even make sense to get rid of the extra directory ~/GNUstep and write Applications, Library, Defaults, etc, directly into user's home dir, as is done on certain other operating systems. Side note: This is good news for whoever creates a desktop environment or distribution around GNUstep: this allows making non-GNUstep software adhere to a different home directory layout. -- Ivan Vučica [email protected]
