rehype-asciimath

ASCIIMath plugin for Rehype

To be used in conjunction with Katex or MathJAX

This uses the ASCIIMathTeXImg.js from the ASCIIMath repo with a patch which is yet to be merged

Example markdown

Wrap your code in backticks (`) inside the dollars ($) for rendering the block using ASCIIMath

ASCIIMath Inline (Use $`...`$), e.g. $`sqrt(x)`$

ASCIIMath Block (Use $$`...`$$), e.g.

$$
`x / (y+z) = \frac{a}{b+c}`
$$

LaTeX inside ASCIIMath should stay as it is

Normal math (without backticks) will render as it is $sqrt(x)$ (LaTeX but no ASCIIMath)

To not parse it as ASCIIMath and still use backticks (at the start or the end), start or end your LaTeX code with empty braces (`{}`), e.g. $`sqrt(x)`{}$

$$
{}`x / (y+z) = \frac{a}{b+c}`
$$
