fast, pure-Ruby Markdown-superset converter

Math Engine KaTeX

This math engine was built-in until kramdown 2.0 and since then is available through the kramdown-math-katex gem.

The engine uses KaTeX via the katex rubygem to convert TeX math formulas into KaTeX HTML, using ExecJS under the hood. This eliminates the need for client-side math-rendering Javascript. This engine is somewhat similar to the SsKaTeX math engine, but easier to use and suitable for kramdown input from untrusted users.

See for the documentation.
