Documentation/Parsers/fonts.md
The fonts parser accepts a directory, which it'll recursively search for font files. Supported file types depend on the target platform, for example iOS only supports TTF and OTF font files.
The default filter for this command is: [^/]\.(?i:otf|ttc|ttf)$. That means it'll accept any file with the extensions otf, ttc or ttf.
You can provide a custom filter using the filter option, it accepts any valid regular expression. See the Config file documentation for more information.
This parser currently doesn't accept any options.
