829 lines
This is a cross-platform program that can parse font files and prints out information such as metrics and font style. It can find fonts installed or your system or you can point it to a specific font file.
Supported font formats:
- OpenType
- TrueType
Supported platforms:
- Unix-like (Fontconfig)
- Windows (DirectWrite; untested)
- MacOS (Core Text; untested)
Usage
See $ font-info --help
for CLI usage documentation. For example, to find
all fonts in the "Liberation Sans" font family on your system and print out
their metrics, run:
$ font-info --family-name "Liberation Sans"

flags.
