Fira 密码破解列表背景

Question

我尝试在带有背景的列表上使用 Fira Code。但是，背景线在 、 和 上方断开(。)起初{我}以为这是自定义字体的普遍问题，但在使用系统中的随机等宽字体 (LiberationMono-Regular) 进行测试后，它似乎工作正常。这是一个 MWE：

\documentclass{article}

\usepackage{fontspec, listings, caption, xcolor, tcolorbox}

\DeclareCaptionFont{white}{\color{white}\bfseries}
\DeclareCaptionFormat{listing}{\colorbox{gray}{\parbox{\dimexpr\linewidth-2\fboxsep\relax}{#1#2#3}}}
\captionsetup[lstlisting]{labelformat=simple,format=listing,labelfont=white,textfont=white}

\lstset{
    basicstyle=\ttfamily,
    backgroundcolor=\color[rgb]{0.9,0.9,0.9},
}

\begin{document}
\begin{lstlisting}[caption=Useful Code (Regular)]
// Some very useful code
// It truly does some amazing stuff
for (int i = 0; i <= matrix->width; i++) {
    for (int j = 0; j < matrix->height; j++) {
        matrix[i][j] = matrix[i][j];
    }
}
\end{lstlisting}
\setmonofont{LiberationMono-Regular.ttf}
\begin{lstlisting}[caption=Useful Code (Liberation)]
// Some very useful code
// It truly does some amazing stuff
for (int i = 0; i <= matrix->width; i++) {
    for (int j = 0; j < matrix->height; j++) {
        matrix[i][j] = matrix[i][j];
    }
}
\end{lstlisting}
\setmonofont{Fira Code Regular}
\begin{lstlisting}[caption=Useful Code (Fira Code)]
// Some very useful code
// It truly does some amazing stuff
for (int i = 0; i <= matrix->width; i++) {
    for (int j = 0; j < matrix->height; j++) {
        matrix[i][j] = matrix[i][j];
    }
}
\end{lstlisting}
\end{document}

注意：在此示例中，我使用了在这个答案。这是一个重要的细节，因为这意味着使用 tcolorbox 的简单解决方案还不够，因为它还会环绕标题，破坏此设计所追求的外观。

为什么会发生这种情况？如何解决？

Answer 1

您可以清楚地看到圆括号和大括号的作用。原因是它们比标准字体中相应的字符高得多。

您有多种选择。

1. 增加内部领先列表

\documentclass{article}

\usepackage{fontspec, listings, caption, xcolor, tcolorbox}

\setmonofont{Fira Code Regular}

\DeclareCaptionFont{white}{\color{white}\bfseries}
\DeclareCaptionFormat{listing}{%
  \colorbox{gray}{%
    \parbox{\dimexpr\linewidth-2\fboxsep\relax}{#1#2#3}%
  }%
}
\captionsetup[lstlisting]{
  labelformat=simple,
  format=listing,
  labelfont=white,
  textfont=white
}

\lstset{
    basicstyle=\linespread{1.1}\ttfamily,
    backgroundcolor=\color[rgb]{0.9,0.9,0.9},
}

\begin{document}

Text \texttt{Text} \{x\}\texttt{\{x\}}

\begin{lstlisting}[caption=Useful Code (Regular)]
// Some very useful code
// It truly does some amazing stuff
for (int i = 0; i <= matrix->width; i++) {
    for (int j = 0; j < matrix->height; j++) {
        matrix[i][j] = matrix[i][j];
    }
}
\end{lstlisting}

\end{document}

2.减小字体大小

\documentclass{article}

\usepackage{fontspec, listings, caption, xcolor, tcolorbox}

\setmonofont{Fira Code Regular}[Scale=MatchLowercase]

\DeclareCaptionFont{white}{\color{white}\bfseries}
\DeclareCaptionFormat{listing}{%
  \colorbox{gray}{%
    \parbox{\dimexpr\linewidth-2\fboxsep\relax}{#1#2#3}%
  }%
}
\captionsetup[lstlisting]{
  labelformat=simple,
  format=listing,
  labelfont=white,
  textfont=white
}

\lstset{
    basicstyle=\ttfamily,
    backgroundcolor=\color[rgb]{0.9,0.9,0.9},
}

\begin{document}

Text \texttt{Text} \{x\}\texttt{\{x\}}

\begin{lstlisting}[caption=Useful Code (Regular)]
// Some very useful code
// It truly does some amazing stuff
for (int i = 0; i <= matrix->width; i++) {
    for (int j = 0; j < matrix->height; j++) {
        matrix[i][j] = matrix[i][j];
    }
}
\end{lstlisting}

\end{document}

或者Scale=0.9
