Subject: system-installed emacs does not find system-installed fonts 
Date: Sun, 06 Mar 2016 13:57:54 -0500

Not technically not a bug because the doc says ...

2.6.2 X11 Fonts

The ‘fontconfig’ package in Guix looks for fonts in
‘$HOME/.guix-profile’ by default.  Thus, to allow graphical applications
installed with Guix to display fonts, you have to install fonts with
Guix as well.

But it does seem counter-intuitive that emacs 'M-x list-fontsets' gives ...

Fontset: -*-*-*-*-*-*-*-*-*-*-*-*-fontset-default
Fontset: -*-fixed-medium-r-normal-*-16-*-*-*-*-*-fontset-standard
Fontset: -urw-Nimbus Mono L-normal-normal-normal-*-13-*-*-*-m-0-fontset-startup

... when the system package list is ...

  % *Guix Package L...      5437 Guix-Output-List
  
  [...]
  emacs                24.5       out       Yes          The extensible, customizable, self-documenting text editor

(I have not checked but) I believe this can be fixed by adding
"/run/current-system/profile/share/fonts" to '--with-add-fonts'
configure flag of the 'fontconfig' package.

For now I think the following recipe should work:

1. Make a file "~/.config/fontconfig/fonts.conf" with the following
   contents:

[fonts.conf (text/plain, inline)]

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <dir>/run/current-system/profile/share/fonts</dir>
</fontconfig>

[Message part 3 (text/plain, inline)]

2. Run "fc-cache -fv".

Indeed.  I realize I did this independently in
e71ef7adaece7e132a5059139122b45083ea1b39.

The better fix will be to rebuild Fontconfig as you suggest.  Would you
like to try that and apply it to ‘core-updates’?

Thanks,
Ludo’.

If you’ve confirmed that passing a comma-separated list here works as
expected, then please push to ‘core-updates’.

Thank you!
