Something which canonicalizes pathnames would be nice though, ifrealpath() cannot be used, is there another way to do it?Currently fontconfig distinguishes even between directory nameslike /foo/bar and /foo/bar/ and /foo//bar although theyare all the same: mfabian@magellan:~$ rm .fontconfig/*mfabian@magellan:~$ fc-cache -v /usr/share/fonts/truetype/usr/share/fonts/truetype: skipping, existing cache is valid: 972 fonts, 0 dirs/var/cache/fontconfig: not cleaning unwritable cache directory/home/mfabian/.fontconfig: cleaning cache directoryfc-cache: succeededmfabian@magellan:~$ fc-cache -v /usr/share/fonts/truetype//usr/share/fonts/truetype/: caching, new cache contents: 972 fonts, 0 dirs/var/cache/fontconfig: not cleaning unwritable cache directory/home/mfabian/.fontconfig: cleaning cache directoryfc-cache: succeededmfabian@magellan:~$ fc-cache -v /usr/share/fonts//truetype/usr/share/fonts//truetype: caching, new cache contents: 972 fonts, 0 dirs/var/cache/fontconfig: not cleaning unwritable cache directory/home/mfabian/.fontconfig: cleaning cache directoryfc-cache: succeededmfabian@magellan:~$ fc-cache -v /usr/share/fonts//truetype/usr/share/fonts//truetype: skipping, existing cache is valid: 972 fonts, 0 dirs/var/cache/fontconfig: not cleaning unwritable cache directory/home/mfabian/.fontconfig: cleaning cache directoryfc-cache: succeededmfabian@magellan:~$ Probably I kept this fc-cache.patch (but commented outin the fontconfig.spec file) to remind me that it wouldbe nice to canonicalize pathnames. -- Mike FABIAN <mfabian@xxxxxxx> http://www.suse.de/~mfabian睡眠不足はいい仕事の敵だ。I � Unicode_______________________________________________Fontconfig mailing listFontconfig@xxxxxxxxxxxxxxxxxxxxxxxxx://lists.freedesktop.org/mailman/listinfo/fontconfig
