在列表环境中转义 $

Question

我试图在 TeX 语言列表中转义美元符号，但不起作用。我试过这个帖子但没有成功。

这是 MWE：

\documentclass[border={10pt 10pt 10pt 10pt}]{standalone}

\usepackage[dvipsnames]{xcolor}

\usepackage{listings}

% Python style for highlighting
\newcommand\latexstyle{\lstset{
  language=TeX,
  basicstyle=\scriptsize\ttfamily,
  mathescape=true,
  keywordstyle=\color{MidnightBlue}\bfseries,
  morekeywords={begin, addplot, addlegendentry, documentclass, usepackage, usetikzlibrary, usepgfplotslibrary, pgfplotsset, nextlist, coordinate small, draw},
}}

% Python environment
\lstnewenvironment{latex}[1][mathescape]
{
\latexstyle
\lstset{#1}
}
{}

\begin{document}

\begin{latex}
 \begin{tikzpicture}
  \begin{loglogaxis}

\addplot+ [ultra thick, dotted] table[]{
  10  0.2
  100  0.1
  1000  0.05}
coordinate [pos=0.15] (A)
coordinate [pos=0.25] (B);
\addlegendentry{legend 1}
\coordinate (A') at ($(A)!3pt!90:(B)$);
\coordinate (B') at ($(B)!3pt!270:(A)$);
\draw (A')-|(B') node[pos=0.25,above]{$1$}
  node[pos=0.75,right]{$\alpha$};
\draw [shorten <=-3pt,shorten >=-3pt] (A') -- (B');

  \end{loglogaxis}
\end{tikzpicture}
\end{latex}

\end{document}

Answer 1

您设置了mathescape=true两次。您可能误解了它的含义：使用mathescape=true，listings当您输入类似以下内容时，将表现得好像是 TeX 数学公式$\alpha$（因此打印数学字母）。我认为您在排版这样的列表时不需要它。

\documentclass[border={10pt 10pt 10pt 10pt}]{standalone}

\usepackage[dvipsnames]{xcolor}

\usepackage{listings}

% Python style for highlighting
\lstdefinestyle{latexstyle}{
  language=TeX,
  basicstyle=\scriptsize\ttfamily,
%  mathescape=true,
  keywordstyle=\color{MidnightBlue}\bfseries,
  morekeywords={
    begin,
    addplot,
    addlegendentry,
    documentclass,
    usepackage,
    usetikzlibrary,
    usepgfplotslibrary,
    pgfplotsset,
    nextlist,
    coordinate small,
    draw
  },
}

% latexn environment
\lstnewenvironment{latex}[1][]
  {\lstset{style=latexstyle,#1}}
  {}

\begin{document}

\begin{latex}
\begin{tikzpicture}
\begin{loglogaxis}

\addplot+ [ultra thick, dotted] table[]{
  10  0.2
  100  0.1
  1000  0.05}
coordinate [pos=0.15] (A)
coordinate [pos=0.25] (B);
\addlegendentry{legend 1}
\coordinate (A') at ($(A)!3pt!90:(B)$);
\coordinate (B') at ($(B)!3pt!270:(A)$);
\draw (A')-|(B') node[pos=0.25,above]{$1$}
      node[pos=0.75,right]{$\alpha$};
\draw [shorten <=-3pt,shorten >=-3pt] (A') -- (B');

\end{loglogaxis}
\end{tikzpicture}
\end{latex}

\end{document}
