Customize TeX renderer

Less than 1 minute...

This cookbook guides you on how to add your own $T E X$ renderer.

@waline/client provides the texRenderer function. The client will pass whether in display mode and the original $T E X$ string as parameters. You should return a string.

A Example Using KaTeX

For KaTeX options, see KaTeX API.
