列表：持续着色的数字

我一直在使用此解决方案在 LaTeX Stack Exchange 上找到我的代码摘录中的着色数字：

它运行得相当好，但不幸的是它也存在一些问题。将其附加到下面我的最小示例上方...：

\begin{document}

\section{Python}

\begin{lstlisting}
def foobar(self):
    var = 123 + 456
    var_2 = 4.56
    var3 = 789
    for _ in range(3):
        print(test)
    if var_2 > 1.23:
        print(1024)
    elif (var3 <= 1000 and var_2 is None):
        print(0)
\end{lstlisting}

\section{Processing}

\begin{lstlisting}
void setup() {
  size(300, 300);
  background(0, 200, 0);
}

void draw() {
  drawFlower(150, 150, 100);
  for (int i = 0; i < 80; i = i+5) {
    line(30, i, 80, i);
  }
  x = x + 0.1;
  y = 0.1 + y;
  if (x > 1.23) {
    x = 0;
    y = 0 ;
  }
}
\end{lstlisting}

\end{document}

...结果是：

在此处输入图片描述

结果还不错，而且特别好的是，该解决方案可以处理变量名中的数字，无论它们后面是否带有下划线（例如var_2和var3）。但上面的例子也显示了几个我无法修复的问题：

  • 可以看到，前面带有(或后面紧跟着的数字)没有颜色，例如range(3)，size(300, 300)
  • 与逗号、冒号或分号等符号相邻的数字也不会被着色；例如，中的中间数字，或或background(0, 200, 0);中的数字x = x + 0.1;if var_2 > 1.23:
  • 另一方面，如果在它们周围留有空格，则可以正确突出显示，例如y = 0 ;（在分号前留有空格）或1000数字elif (var3 <= 1000 and var_2 is None):

有人能帮我调整这个代码片段，以便在这些情况下数字能够始终突出显示，但变量和函数名称却不会突出显示吗？

编辑：简而言之，如果出现以下情况，我希望突出显示数字：

  • 它们位于以下任意字符之后：，，，，，，.({[:
  • 它们位于以下任意字符之前：，，，，，，，.)}]:;
  • 但绝对不包括_在任何一个组中，因为这可能会破坏许多代码片段中的变量命名约定（即使 Python 确实接受_数字来帮助视觉识别 10^3 组，如x = 1_000_000。

目前，上述代码只能正确识别上述.要点中提到的所有字符。

编辑：不幸的是，minted这对我来说不是一个选择，它不能很好地与我的论文文件兼容。

答案1

考虑使用minted并定制样式表。

在此处输入图片描述

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{minted}

\usemintedstyle{colorful}

\begin{document}

\begin{minted}{python}
def foobar(self):
    var = 123 + 456
    var_2 = 4.56
    var3 = 789
    for _ in range(3):
        print(test)
    if var_2 > 1.23:
        print(1024)
    elif (var3 <= 1000 and var_2 is None):
        print(0)
\end{minted}

\begin{minted}{c}
void setup() {
  size(300, 300);
  background(0, 200, 0);
}

void draw() {
  drawFlower(150, 150, 100);
  for (int i = 0; i < 80; i = i+5) {
    line(30, i, 80, i);
  }
  x = x + 0.1;
  y = 0.1 + y;
  if (x > 1.23) {
    x = 0;
    y = 0 ;
  }
}
\end{minted}

\end{document}

答案2

如果我理解了这个问题，那么你想给所有数字上色，除非它们是关键字或标识符。你可以使用带有彩色数字的字体作为基本字体，并为关键字使用不同的字体。使用 lualatex 可以实现这一点：

\documentclass{article}
\usepackage{listings,xcolor}
\usepackage{fontspec}

\directlua{
 luaotfload.add_colorscheme("colordigits",
   {
    ["FF00FF"] = {"one","two","three","four","five","six","seven","eight","nine","zero"},
   })}

\newfontfamily\colordigits{Latin Modern Mono}[RawFeature={color=colordigits}]

\lstset{
    basicstyle = \colordigits,
    identifierstyle = \ttfamily\color{blue},
    keywordstyle = \ttfamily\color{green!80!black},
    keywords = {foo},
    moredelim = [il][]{**},
    moredelim = [l][\color{gray}]{/},
    morestring = [d][\color{gray}]{"},
    morestring = *[d][\color{gray}\itshape]{!},
    morestring = **[d][\color{gray}\itshape]{?},
}
%
\begin{document}

\begin{lstlisting}
def foobar(self):
    var = 123 + 456
    var_2 = 4.56
    var3 = 789
    for _ in range(3):
        print(test)
    if var_2 > 1.23:
        print(1024)
    elif (var3 <= 1000 and var_2 is None):
        print(0)
\end{lstlisting}

\section{Processing}

\begin{lstlisting}
void setup() {
  size(300, 300);
  background(0, 200, 0);
}

void draw() {
  drawFlower(150, 150, 100);
  for (int i = 0; i < 80; i = i+5) {
    line(30, i, 80, i);
  }
  x = x + 0.1;
  y = 0.1 + y;
  if (x > 1.23) {
    x = 0;
    y = 0 ;
  }
}
\end{lstlisting}

答案3

为完整性起见，在 xetex 中使用 interchartoks 的非 Lua 解决方案在最后一刻失败了，因为 lstlistings 在标记之间插入了胶水。interchartoks 将胶水视为单词间边界标记。

因此，即使 pdflatex 场景是可以克服的，也没有答案（没有包重写（使用零宽度连接器？）。

为了说明标记类别之间的转换：

红色是单词边界到数字的过渡。
