ConTeXt Font Database Management
0.21
save open type font in raw table
save a tma file in a more readable format
generate new font database (use when in doubt)
:generate luatex-fonts-names.lua (not for context!)
: list installed fonts, filter by name []
: list installed fonts, filter by spec []
: list installed fonts, filter by file []
filter files using pattern
key-value pairs
show all found instances (combined with other flags)
give more details
enable trackers
some info about the database
Examples
mtxrun --script font --list somename (== --pattern=*somename*)
mtxrun --script font --list --name somename
mtxrun --script font --list --name --pattern=*somename*
