TeX

the Markdown file in your VuePress site support the $TEX$ syntax.

Settings

Install related $TEX$ package katex or mathjax-full in your project:

pnpm

pnpm add -D katex
# or
pnpm add -D mathjax-full

yarn

yarn add -D katex
# or
yarn add -D mathjax-full

npm

npm i -D katex
# or
npm i -D mathjax-full

Then enabling via:

import { hopeTheme } from "vuepress-theme-hope";

export default {
  theme: hopeTheme({
    plugins: {
      markdownMath: {
        type: "katex", // or 'mathjax'
      },
    },
  }),
};

Syntax

• Inline mode: $xxx$

• Display mode:

  $$xxx$$
  
  $$
  xxx
  $$

Escaping

Escaping can be done by using \ before the $ character, or adding space both before and after the $ character.

The $a=1$ is a TeX equation, while $ a=1 $ and $a=1$ is not.

Escaping can be done by using `\` before the `$` character, or adding space both before and after the `$` character.

The $a=1$ is a TeX equation, while $ a=1 $ and \$a=1$ is not.

Demo

Inline

Euler's identity $e^{i\pi }+1=0$ is a beautiful formula in ${\mathbb{R}}^2$.

Euler's identity $e^{i\pi}+1=0$ is a beautiful formula in $\mathbb{R}^2$.

Display

$$\frac{{\partial }^r}{\partial {\omega }^r}\left(\frac{y^{\omega }}{\omega }\right)=\left(\frac{y^{\omega }}{\omega }\right)\{(\log y{)}^r+\sum _{i=1}^r\frac{(-1{)}^{I}r\cdots (r-i+1)(\log y{)}^{ri}}{{\omega }^i}\}$$

$$
\frac {\partial^r} {\partial \omega^r} \left(\frac {y^{\omega}} {\omega}\right)
= \left(\frac {y^{\omega}} {\omega}\right) \left\{(\log y)^r + \sum_{i=1}^r \frac {(-1)^ Ir \cdots (r-i+1) (\log y)^{ri}} {\omega^i} \right\}
$$

Playground

Input

\frac {\partial^r} {\partial \omega^r} \left(\frac {y^{\omega}} {\omega}\right) = \left(\frac {y^{\omega}} {\omega}\right) \left\{(\log y)^r + \sum_{i=1}^r \frac {(-1)^ Ir \cdots (r-i+1) (\log y)^{ri}} {\omega^i} \right\}

Output

$$\frac {\partial^r} {\partial \omega^r} \left(\frac {y^{\omega}} {\omega}\right) = \left(\frac {y^{\omega}} {\omega}\right) \left\{(\log y)^r + \sum_{i=1}^r \frac {(-1)^ Ir \cdots (r-i+1) (\log y)^{ri}} {\omega^i} \right\}$$

Using KaTeX

When using KaTeX, any other options will be passed to KaTeX as KatexOptions. See KaTeX Docs for all available options.

Besides, 2 special options are supported:

• copy: enable copy extension or not.
• mhchem: enable mhchem extension or not.

Using MathJax

When using MathJax, you can set:

• tex: options which is passed to TeX input parser
• output: either 'svg' (default) or 'chtml' to change output format between SVG and HTML.
• chtml: options which is passed to Common HTML output parser
• svg: options which is passed to SVG output parser
