Quartz uses Katex by default to typeset both inline and block math expressions at build time.

Formatting

Block Math

Block math can be rendered by delimiting math expression with $$.

$$
f(x) = \int_{-\infty}^\infty
    f\hat(\xi),e^{2 \pi i \xi x}
    \,d\xi
$$

f(x) = \int_{-\infty}^\infty
    f\hat(\xi),e^{2 \pi i \xi x}
    \,d\xi

Inline Math

Similarly, inline math can be rendered by delimiting math expression with a single $. For example, $e^{i\pi} = -1$ produces e^{i\pi} = -1

Escaping symbols

There will be cases where you may have more than one $ in a paragraph at once which may accidentally trigger MathJax/Katex.

To get around this, you can escape the dollar sign by doing \$ instead.

For example:

• Incorrect: I have $1 and you have $2 produces I have $1 and you have $2
• Correct: I have \$1 and you have \$2 produces I have $1 and you have $2

MathJax

In quartz.config.ts, you can configure Quartz to use MathJax SVG rendering by replacing Plugin.Latex({ renderEngine: 'katex' }) with Plugin.Latex({ renderEngine: 'mathjax' })

Customization

• Removing Latex support: remove all instances of Plugin.Latex() from quartz.config.ts.
• Plugin: quartz/plugins/transformers/latex.ts
