使用Pandoc将HTML Mathjax转换为Markdown [英] Convert html mathjax to markdown with pandoc

问题描述

我有一些html文件，包括mathjax命令. 我想使用pandoc将其转换为php额外的markdown.

I have some html files including mathjax commands. I would like to translate it into php extra markdown using pandoc.

问题是pandoc在所有数学命令之前添加"\".例如 \ begin {equation} \ $ x \ ^ 2 等等

The problem is that pandoc add "\" before all math commands. For example \begin{equation} \$ x\^2 etc

您知道如何通过pandoc避免这种情况吗? 我认为与此相关的问题是:如何转换使用pandoc将带有mathjax的HTML转换为乳胶?

Do you know how to avoid that with pandoc ? I think a related question is this one : How to convert HTML with mathjax into latex using pandoc?

推荐答案

您可以编写一个简短的Haskell程序unescape.hs:

You can write a short Haskell program unescape.hs:

-- Disable backslash escaping of special characters when writing strings to markdown.
import Text.Pandoc

main = toJsonFilter unescape
  where unescape (Str xs) = RawInline "markdown" xs
        unescape x        = x

现在使用ghc --make unescape.hs进行编译.并与

Now compile with ghc --make unescape.hs. And use with

pandoc -f html -t json | ./unescape | pandoc -f json -t markdown

这将禁止在markdown输出中转义特殊字符(如$).

This will disable escaping of special characters (like $) in markdown output.

一种更简单的方法可能是通过sed传递pandoc的常规markdown输出:

A simpler approach might be to pipe pandoc's normal markdown output through sed:

pandoc -f html -t markdown | sed -e 's/\\\([$^_*]\)/\1/g'
