Re: Check if a font is currently installed

[Valentin Petzel]

Hello Paolo,

Theoretically it should be enough to check if #(ly:font-config-get-font-file 
font-name) is false, but at least on my system this returns just some 
arbitrary but fixed font file if the font is not found. It should definitely 
not behave this way, gotta look into this.

Cheers,
Valentin
