Fonts packaging macros rework early peek

Hi, To all that may concern (mainly, packagers of things that include font files). I’m currently reworking the font automation I created for Fedora 10 years ago. You can get an early peek at the result here: https://copr.fedorainfracloud.org/coprs/nim/fontpackages-2/ The main objectives of the rework are: * make it easier to use * generate appstream files automatically, and validate the result * you can of course handcraft your own appstream file, or use the one shipped by your upstream, if that thing actually exists * remove more boilerplate code in the specs * move to a more declarative syntax * it is slightly more verbose but you don't need to remember magic macro flags, just to cut and paste a block of variables and fill in their values * remove historical implementation quirks * enforce Fedora naming guidelines some more at the macro level, since reading those is too much work for some packagers * completely cut the relationship between font subpackages and the srpm they’re generated from, so any Fedora package that includes fonts can use those without side effects on the rest of the spec * move to generic macro naming, that can be templated away by rpm in the future So, it's a technical implementation rework, without any change in the packaging principles that exist in current guidelines. At this stage I'm pretty sure the way macros will be used in specs is stabilized, so you can take a look at the specs in copr and comment if there are things you'd like to be done differently. The declaration order is not too intuitive, mostly because it differs from Fedora habits, but each change was driven by rpmbuild, copr or mock requirements, so don't order things back unless you want to discover the hard way why it needs to be like that. Finally, I do realise the proposal, if accepted, will mean rewriting part of existing font specs at one point, which no one wants to do, but: 1. it's less work than writing appstream files and the associated spec code manually (do *you* validate your appstream files correctly today in your specs?), 2. it mostly involves removing spec lines → less lines for packagers to maintain in the future 2. I did this work for my own font packages, and there are lots of them, so believe me I tried to make it as simple as possible, starting for myself 4. I don't think some spec churn every 10 years is too much to ask The remaining todo is mainly to clean up the layout of the macro package itself, write templates, and do some guidelining (and bug fixing, if needed). If you want to rebuild any of the packages or specs on you system you need the redhat-rpm-config and rpm version in copr, as the font macros depend on their changes. Those changes are currently being integrated in rawhide for other reasons, and a backport to stable is also on the agenda. You’ll see in the copr some badly needed updates to some important Fedora font packages (dejavu, stix, droid, etc). I officially suck at updates. I'm reworking things to help me suck less. Also, I took the opportunity to package some font families that should have been packaged quite a long time ago (not necessarily by myself). All this will hit rawhide and reviews once the macro work is done. Regards, -- Nicolas Mailhot
