KaTeX有bookdown + gitbook

Question

我正在构建一个bookdown项目，并将其呈现为一个带有大量数学页面的gitbook，并且呈现缓慢。我想使用KaTeX而不是mathJax来渲染我的数学，但我不确定如何使它工作。有一个gitbook plugin所以它应该是可能的，但我不太清楚如何将其与bookdown集成。

在我的index.Rmd文件中，我尝试了以下内容：

---
site: bookdown::bookdown_site
output:
  bookdown::gitbook:
    pandoc_args: [--katex]
    mathjax: NULL
    includes:
      in_header: katex.html
documentclass: book
---

其中katex.html由KaTeX的样式表和主题组成。

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.7.1/katex.min.css" integrity="sha384-wITovz90syo1dJWVh32uuETPVEtGigN07tkttEqPv+uR2SE/mbQcG7ATL28aI9H0" crossorigin="anonymous">
<script src="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.7.1/katex.min.js" integrity="sha384-/y1Nn9+QQAipbNQWU65krzJralCnuOasHncUFXGkdwntGeSvQicrYkiUBwsgUqc1" crossorigin="anonymous"></script>

但是，数学不会渲染（除了仍然由MathJax渲染的一些部分）。

我有什么方法可以预订与KaTeX合作吗？

您似乎没有阅读KaTeX文档。 KaTeX不会自动呈现您的数学表达式。请参阅Github上README中的Automatic rendering of math on a page部分。简而言之，您必须加载auto-render.min.js并添加一个事件来渲染数学，例如在katex.html中，您需要：

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.7.1/katex.min.css" integrity="sha384-wITovz90syo1dJWVh32uuETPVEtGigN07tkttEqPv+uR2SE/mbQcG7ATL28aI9H0" crossorigin="anonymous">
<script src="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.7.1/katex.min.js" integrity="sha384-/y1Nn9+QQAipbNQWU65krzJralCnuOasHncUFXGkdwntGeSvQicrYkiUBwsgUqc1" crossorigin="anonymous"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.7.1/contrib/auto-render.min.js" integrity="sha384-dq1/gEHSxPZQ7DdrM82ID4YVol9BYyU7GbWlIwnwyPzotpoc57wDw/guX8EaYGPx" crossorigin="anonymous"></script>
<script>
  document.addEventListener("DOMContentLoaded", function() {
    renderMathInElement(document.body);
  });
</script>

要在bookdown gitbook输出中禁用MathJax，您需要在YAML中设置math: false，例如

---
site: bookdown::bookdown_site
output:
  bookdown::gitbook:
    pandoc_args: [--katex]
    mathjax: NULL
    includes:
      in_header: katex.html
documentclass: book
math: false
---

katex.html

然后在我使用的YAML中：

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.11.1/dist/katex.min.css" integrity="sha384-zB1R0rpPzHqg7Kpt0Aljp8JPLqbXI3bhnPWROx27a9N0Ll6ZP/+DiW/UqRcLbRjq" crossorigin="anonymous">

<!-- The loading of KaTeX is deferred to speed up page rendering -->
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.11.1/dist/katex.min.js" integrity="sha384-y23I5Q6l+B6vatafAwxRu/0oK/79VlbSz7Q9aiSZUvyWYIYsd+qj+o24G5ZU2zJz" crossorigin="anonymous"></script>

<!-- To automatically render math in text elements, include the auto-render extension: -->
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.11.1/dist/contrib/auto-render.min.js" integrity="sha384-kWPLUVMOks5AQFrykwIup5lo0m3iMkkHrD0uJ4H5cjeGihAutqP0yW0J6dpFiVkI" crossorigin="anonymous" onload="renderMathInElement(document.body);"></script>

值得注意的是，我发现有必要使用--- site: bookdown::bookdown_site output: bookdown::gitbook: pandoc_args: [--katex] mathjax: NULL includes: in_header: katex.html documentclass: book math: true --- 而不是math: true。
