mathjax-pandoc-filter

Install via npm i mathjax-pandoc-filter

Example usage:

echo '$$a_i$$' | pandoc --filter ~/node_modules/.bin/mathjax-pandoc-filter

Or, if you have npm bin in PATH, just

echo '$$a_i$$' | pandoc --filter mathjax-pandoc-filter

Configuration

The filter will check Pandoc metadata for the following boolean options:

mathjax.centerDisplayMath

Will add text-align: center style to display math paragraphs
mathjax.noInlineSVG

Will render math as img tags instead of inline svg
mathjax

Will be converted to JS object and passed to MathJax.config. Refer to MathJax-node documentation for details.
mathjax.typeset

Will be unified with default typeset options and passed to each call of MathJax.typeset. Refer to MathJax-node documentation for details.

Values here will override the defaults.

Note: you can override any values, but you probably don't want to touch math and svg at least.

Example:

echo '$$a_i$$' | pandoc --filter mathjax-pandoc-filter -Mmathjax.centerDisplayMath -Mmathjax.noInlineSVG

You can also specify this options in Markdown document's YAML header:

---
mathjax.centerDisplayMath: true
mathjax.noInlineSVG: true
mathjax.typeset:
  cjkCharWidth: 15
---

$$a_i$$

Note: you can't set mathjax or mathjax.typeset from command line.
