Newbe that would like to contribute improvements

[Pander-2]

Hi all,

I'm a complete newby at configuring fontconfig and would like some
pointers on how to get started. I have a lot of information on fonts
that can be made better available in fontconfig and would like to be
able to add that in my fontconfig configuration and submit to this
project so more open and free fonts are supported better.

For example, I have a font that is made available like this:

fc-list : family style file|grep -i justus
Justus-Roman.ttf: Justus:style=Roman
Justus-Bold.ttf: Justus:style=Bold
Justus-Italic.ttf: Justus:style=Italic
Justus-Versalitas.ttf: Justus:style=Versalitas
Justus-Oldstyle.ttf: Justus:style=Oldstyle
Justus-ItalicOldstyle.ttf: Justus:style=ItalicOldstyle

What minimal configuration to I need to do add in /etc/fonts in order to
get this as output, see _text between underscores_ for changes:

fc-list : family style file|grep -i justus
Justus-Roman.ttf: Justus:style=Roman
Justus-Bold.ttf: Justus:style=Bold
Justus-Italic.ttf: Justus:style=Italic
Justus-Versalitas.ttf: Justus_ Versalitas_:style=_Roman_
Justus-Oldstyle.ttf: Justus_ Oldstyle_:style=_Roman_
Justus-ItalicOldstyle.ttf: Justus_ Oldstyle_:style=_Italic_

If someone would get me up to speed with this I can submit a series of
fixes and new additions. Note, I'm not too lazy to read the manual.
Because I'm new to this, I'm just looking on how to get started quickly
in a way that the developers can work with this as best as possible and
have fontconfig support more open and free fonts better.

Regards,

Pander

Hi Pander,

Your problem is that this specific font does not conform to WWS conventions.
Fontconfig is just displaying the info declared by the font files. You can
workaround it at fontconfig level, but it is always worthwhile to get it fixed
upstream as your workaround will be only available to fontconfig apps (and
only the ones using your specific fontconfig version)

This is what the Fedora font checker would tell you about this:

Font upstream task, with packager workarounds

This WWS-like test checks if font styles use the WWS “Width (Stretch)”,
“Weight”, “Slope (Slant/Style)” naming convention¹. As noted by Adobe² the
W3C CSS font family model is less than ideal, but it is a standard and
applications expect it.

Since *nix applications do not workaround bad font naming with dynamic
renaming heuristics (unlike Microsoft WPF), achieving consistent naming
requires fixing it directly in the font files. For this reason we test
font style naming separately from font family naming, and do not support
complex weight abbreviations and suffixes³.

To pass this test make sure style names do not include any qualifier not
defined in the WWS white-paper¹, and that “Width (Stretch)”, “Weight”,
“Slope (Slant/Style)” are defined only once. Any other face qualifier
belongs in the font family name.

If one your font files is listed here please ask its upstream to fix its
naming so it respects WWS conventions and does and does not need further
reprocessing.

Packager workaround: patch the file (if it is available in .sfd format),
or add a fontconfig rule to your package to hide the problem⁴.

³ As defined in the end of the WWS renaming algorithm described in the
  Microsoft whitepaper.
⁴ cf the “fontpackages” remapping template; unfortunately this workaround
  won't fix problems for non-fontconfig applications, or when
  interoperating with other systems.
