Math Support [guide-0004]

tr use $\color{#329894}\KaTeX$ in two forms: @m{...} and @mm{...}. One for inline and one for block, e.g.

• @m{a \in \R} produces $a \in \R$
• @mm{ \int_{a}^{b} x^2 \,dx } produces $$\int_{a}^{b} x^2 \,dx$$

Except $\color{#329894}\KaTeX$, tr also supports backend $\color{#008080}\LaTeX$ solution, you can put tikz program in @tikzcd{...} block to draw quiver, for example

Or @texfig{...} for more flexible input (anything allowed in $\color{#008080}\LaTeX$ document block). For example

@texfig{
...
}

If you want to use packages, write as below (the change is introduced since texfig now must manually assigns LaTeX header part)

@texfig[#:header @"
\\usepackage{tikz}
\\usetikzlibrary{spath3, intersections, backgrounds}
"]{
...
}

We support @typst{...} which use $\color{#239dad}\text{Typst}$ as backend, check Typst backend for more information.
