TeX-to-MathML conversion library in JavaScript

Temml is a LaTeX-to-MathML JavaScript conversion utility. It is built to be lightweight.

Library	Minified JavaScript + CSS
Temml	147 KB
MathJax 2.7.5	338 KB
KaTeX	280 KB
TeXZilla	168 KB

As a futher advantage, Temml can use local system fonts. The minimum Temml installation serves a font file that is only 12kb. Sadly, Chromium has some rendering bugs when using system fonts. It work better with the Latin Modern font, a 380 KB file.

Temml’s coverage of LaTeX functions is as good as MathJax, slightly better than KaTeX 0.16.0 and substantially better than TeXZilla. See a detailed coverage comparison.

Temml's test suite includes many rendered examples, including the Temml supported functions page and tests from Mozilla, Wikipedia, mhchem, and LaTeXML.

Temml's demonstration page is at https://temml.org/

Documentation can be found at:

• Installation

• LaTeX function support, sorted into logical groups.

• LaTeX function support, sorted alphabetically.

Acknowledgements

I built Temml by:

1. Forking KaTeX.

2. Deleting half the code, removing the HTML parts and keeping the parser, the macro expander, and the MathML parts.

3. Doing some code refactoring and many MathML bug fixes.

4. Adding new functionality: upright lower-case Greek letters, \euro, \label{…}, \ref{…}, \prescript, \definecolor, xcolor color names, etc.

I wish to thank Khan Academy and the many volunteer KaTeX contributors. This library would not exist if KaTeX had not existed first.
