### 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 Perl module `JSON`. You can install this either from CPAN
|
||||
(e.g. using the `cpan` command line tool: `cpan install JSON`)
|
||||
or with your package manager.
|
||||
|
||||
- You need the Python module `fonttools`. You can install this either from PyPI
|
||||
(using `easy_install` or `pip`: `pip install fonttools`)
|
||||
or with your package manager.
|
||||
|
||||
Once you have these things, run the following command from the root directory:
|
||||
|
||||
sh ./docker/fonts/buildMetrics.sh
|
||||
|
||||
which should generate new metrics and place them into `fontMetricsData.json`.
|
||||
You're done!
