Created attachment 1177790 [details] Add JavaScript, Lua and Vala to $buildin_gettext_support intltool is unmaintained upstream and it currently has a couple of bugs that are very problematic. One of them is that various formats are not detected by intltool-update: https://bugs.launchpad.net/intltool/+bug/544445 https://bugs.launchpad.net/intltool/+bug/1039983 I have submitted a simple patch that fixes the issue, but it is unlikely to get merged and released: https://bugs.launchpad.net/intltool/+bug/1325597 I'm asking to include the patch in the Fedora package.
