tex-to-mathml-svg

Converts TeX expression into MathML and SVG using MathJax and PhantomJS.

Install PhantomJS into /usr/bin/ and run tex-to-mathml-svg.js or manually invoke the script as follows, which would emit the original expression, MathML, and SVG:

<PathToPhantomJS>/phantomjs tex-to-mathml-svg.js "y = 2x + 1" "\frac{1}{2}"

When multiple expressions are passed into the script, the generated SVG markups share the glyph definitions included in the first SVG so they all need to appear in a single document.

Integrating into Jekyll

You can also use it as a Jekyll plugin. Put it into your site's _plugins directory. The following configuration options are available in _config.yml under tex_to_mathml_svg:

• phantomjs: The absolute path to PhantomJS binary. Defaults to /usr/bin/phantomjs
• enable_in_serve_watch: Since this plugin is extremely slow, it doesn't run inside serve -w by default. Set this option to true to generate MathML/SVG inside serve -w.
• disable: Always disables the MathML/SVG generation when set true.
• disable_mathml: Disables MathML generation.
• inline_start: The delimiter for the start of an inline (contains no new line) TeX expression. Defatuls to $.
• inline_end: Ditto for the end.
• outofline_start: The delimiter for the start of an out-of-line MathML expression. Defaults to $$.
• outofline_end: Ditto for the end.
