How to generate new metrics

There are several requirements for generating the metrics used by KaTeX.

  • You need to have an installation of TeX which supports kpathsea. You can check this by running tex --version, and seeing if it has a line that looks like

    kpathsea version 6.2.0

  • You need the JSON module for perl. You can install this either from CPAN (possibly using the cpan command line tool) or with your package manager.

  • You need the python module fonttools. You can install this either from PyPi (using easy_install or pip) or with your package manager.

Once you have these things, run

make metrics

which should generate new metrics and place them into fontMetricsData.json. You're done!
