goldmark-treeblood is an extension for goldmark that renders $LaTeX$ expressions as MathML, an open web standard for describing mathematical notation. Unlike MathJax or KaTeX, TreeBlood runs server-side, is written in pure Go, and has no dependencies outside the Go standard library.

To use goldmark-treeblood, import the goldmark-treeblood package

import "github.com/wyatt915/goldmark-treeblood"

and include treeblood.MathML in the list of extensions passed to goldmark

goldmark.New(
  goldmark.WithExtensions(
    // ...
    treeblood.MathML(),
  ),
  // ...
).Convert(src, out)

This extension respects both TeX-style delimiters $...$ and $$...$$ as well as their more modern AMS $LaTeX$ counterparts \(...\) and \[...\].
