python - 如何清理 LaTeX 输入？

Question

我想接受用户输入（有时这将是大段落）并生成一个 LaTeX 文档。我正在考虑使用几个简单的正则表达式来替换\with\textbackslash的所有实例以及{or的所有实例}与\}or \{。

我怀疑这是否足够。我还需要做什么？注意：如果有为此制作的特殊库，我正在使用 python。

为了澄清，我不希望任何东西被解析为 LaTeX 语法：$a$应该替换为\$a\$.

Answer 1

If your input is plain text and you are in a normal catcode regime, you must do the following substitutions:

• \ → \textbackslash{} (note the empty group!)
• { → \{
• } → \}
• $ → \$
• & → \&
• # → \#
• ^ → \textasciicircum{} (requires the textcomp package)
• _ → \_
• ~ → \textasciitilde{}
• % → \%

In addition, the following substitutions are useful at least when using the OT1 encoding (and harmless in any case):

• < → \textless{}
• > → \textgreater{}
• | → \textbar{}

And these three disable the curly quotes:

• " → \textquotedbl{}
• ' → \textquotesingle{}
• ` → \textasciigrave{}
