Description:
According to the Font package guidelines[1], it is no longer necessary to add a dependency on fontconfig or xorg-mkfontscale. For some fonts, there were already requests to remove these dependencies ( FS#66005 ), so here is a list of (hopefully) all affected packages that could be used to create a TODO entry.

[1] https://wiki.archlinux.org/index.php/Font_packaging_guidelines#Dependencies

The list was generated by this command:
pacman -Fqx '\.(o|t)tf' | expac -S '%n %E' - | sort | grep -e fontconfig -e xorg-mkfontscale | sed 's/ .*$//'

These packages were manually removed, because they look like false positives:
ardour
ghostscript
grafana
grafx2
lilypond
qt5-base
vlc

The list of affected font packages:

adobe-source-han-sans-cn-fonts
adobe-source-han-sans-hk-fonts
adobe-source-han-sans-jp-fonts
adobe-source-han-sans-kr-fonts

I've just noticed that there are font packages which depend on xorg-font-utils[1] instead of xorg-mkfontscale, so this dependency could be removed as well. The list above is still up-to-date, because the font packages depending on xorg-font-utils were already included.

The list does not contain font packages that depend on fontconfig only. Examples are ttf-arphic-{ukai,uming}.

See also the discussion thread [1] and another similar feature request [2].

Good catch! The list only includes packages that contain files ending with .ttf or .otf. The packages you mentioned apparently use a "TrueType Collection" which has the file extension .ttc[1]. I'm sure there are more packages that are not included, but as far as I know, there is no easy way to identify all font packages. Therefore, I would suggest to first fix the packages in the list and afterwards manually check the packages that still depend on fontconfig / xorg-mkfontscale / xorg-font-utils for missed font packages.

Yes please, this is long overdue. On most desktop systems this won't matter because people are going to have those packages for other reasons. Anything that uses fonts via fontconfig or any system with X will have the right packages and hence hooks.

However there are things you can do with fonts that don't involved fontconfig and even more than don't involve X! Having these dependencies makes it really cumbersome to create lightweight containers for specific purposes. I don't want my CI tooling that uses a font for something to need xorg or fontconfig and the heft they bring unless I specifically need them for some reason. Having these unnecessary deps dropped across the official repos will also make it easier to convince AUR maintainers to stop including them.

Unfortunately, the discussion on the mailing list ended without a decision [1]. How can we proceed with this request?

By assuming it's time to proceed, I guess. :D

Due to lack of objections I've posted to arch-dev-public with my intent to implement this tonight.

The TODO is missing bitmap fonts:

extra/bdf-unifont
community/dina-font
community/tamsyn-font
community/terminus-font
community/terminus-font-otb
Comment by Andreas Radke (AndyRTR) - Monday, 29 June 2020, 15:03 GMT
Is there anything left? All packages from Todo Lists have been fixed.
Comment by xduugu (xduugu) - Tuesday, 30 June 2020, 09:08 GMT
Thanks Eli for setting up the Todo list and everyone involved for fixing the font packages.

I have found two more packages that still depend on fontconfig and are missing from the Todo list, because they contain fonts in some uncommon font formats:
- font-bitstream-speedo [1]: fonts use file extension .spd
- terminus-font-otb [2]: fonts use file extension .otb

According to Wikipedia[3], Speedo is "an obsolete scale font format" and support for it was "removed from X in the X11R7.0 release in 2005". In my understanding, the package font-bitstream-speedo is of little use today and could be dropped, but I may be wrong.

Removed package font-bitstream-speedo.
Fixed terminus-font-otb.
