I have an application where I want to use relative paths in symlinks (so that rsyncing to a different machine with a different root directory produces something with the same effect). So I want makeRelative "/var/www/this_server/foo/bar/" "/var/www/this_server/bob" to return "../../bob" (which would then be used to create a symlink) so that if I copy the tree below /var/www/this_server to /var/www/that_server (perhaps on a different machine, but copying the symlinks without rewriting them), the symlinks point to the same files. On posix at least, this would permit isRelative (makeRelative a b) always to be True, which is a pleasant property for it to have. Is there any reason that System.FilePath.Posix.makeRelative should not do this? I don’t know enough about non-posix filesystems to know whether it even makes sense elsewhere. -- Jón Fairbairn Jon.Fairbairn@cl.cam.ac.uk
