Hello,
it would be useful to have a functions that checks if a font with a specific font-name is currently installed, so to have the produced score without visual errors that are not always easy to detect.
I searched a bit in the list of the scheme helper functions, and could find only:
ly:font-config-get-font-file font-name
However, in case the file is not found, it defaults to some font that (I suppose) is OS dependent, then I don't know how to check if the searched font is really installed. Any idea about this?
Thanks very much!
P
