The font packages are tagged with languages they support as well as the families they provide. For now, Pango+PackageKit only detect the missing language support case and offer installing fonts for the language. The PackageKit API supports suggesting installing families too. Apps like OO.o can use that. The problem however is how to detect a missing font, given all the aliasing that goes on. For example, if the document asks for Arial, and user has Liberation installed, the requirement is satisfied, but it's hard to detect. On the other hand, if Liberation is not installed, PackageKit currently has no way to know that the liberation-fonts package provides Arial compat fonts. Those kind of aliases need to be added manually on a per package basis. All in all, family-based autoinstallation is planned, but not fully fleshed out yet. behdad > C. > -- Fedora-desktop-list mailing list Fedora-desktop-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-desktop-list
