[solved] Using fonts in a derivation

in configuration.nix I can use fonts.fonts to specify fonts. But
how do I do this in a derivation?

Is the technique used by libreoffice expression enough for you needs?

Nix:

fontsConf = makeFontsConf {
  fontDirectories = [ dejavu_fonts (…) ];
 };

Build phase:

cp "${fontsConf}" fonts.conf
export FONTCONFIG_FILE="$PWD/fonts.conf"

Perfect! Thank you very much.
