如何在列表标签​​后添加冒号？

我想在 lstlistoflistings 中的每个 lstlistingname 后面添加一个冒号“：”。

目前它向我显示“代码 1 StatusCalculator 初始化.....”但我希望在 lstlistingname 后面有一个冒号“代码 1：StatusCalculator 初始化...”

我无法运行它。有人能帮助我吗？

\documentclass[12pt, a4paper, oneside]{scrartcl}

\usepackage[utf8]{inputenc}
\usepackage{textcomp}
\usepackage[ngerman]{babel}
\usepackage[hidelinks=true]{hyperref}
\usepackage[final]{pdfpages}

\definecolor{grey}{gray}{0.9}

\usepackage{listings}
\renewcommand\lstlistingname{Code}
\lstloadlanguages{Ruby}
\lstset{%
basicstyle=\small\ttfamily\color{black},
commentstyle = \ttfamily\color{red},
keywordstyle=\ttfamily\color{blue},
stringstyle=\color{orange},
backgroundcolor=\color{grey},
columns=fullflexible}

\usepackage{color}
\usepackage{xcolor}

\usepackage{caption}
\DeclareCaptionFont{white}{\color{white}}
\DeclareCaptionFormat{listing}{\colorbox{gray}{\parbox{\textwidth}{#1#2#3}}}
\captionsetup[lstlisting]{format=listing,labelfont=white,textfont=white}

\let\oldlstlistoflistings\lstlistoflistings
\renewcommand{\lstlistoflistings}{%
  \begingroup%
  \let\oldnumberline\numberline%
  \renewcommand{\numberline}{\lstlistingname~\oldnumberline}%
  \oldlstlistoflistings%
  \endgroup}

\usepackage{geometry}
\geometry{a4paper, top=25mm, left=25mm, right=25mm, bottom=20mm, headsep=10mm, footskip=12mm}

\begin{document}

 \renewcommand\lstlistlistingname{Codelisting}
 \addcontentsline{toc}{section}{Codelisting}
 \lstlistoflistings
 \newpage

  \begin{lstlisting}[language=Ruby, caption=StatusCalculator Initialize, label=initialize]
  def initialize(project_id)
    @project = Project.find(project_id)
  end
  \end{lstlisting}

\end{document}

为了达到你想要的，诀窍

\let\oldlstlistoflistings\lstlistoflistings
\renewcommand{\lstlistoflistings}{%
  \begingroup%
  \let\oldnumberline\numberline%
  \renewcommand{\numberline}{\lstlistingname~\oldnumberline}%
  \oldlstlistoflistings%
  \endgroup}

是不足够的...

您必须加载该包tocloft并使用它。

首先，您必须将列表注册到tocloft，如本说明中所述回答代码中的 egreg

\makeatletter
\begingroup\let\newcounter\@gobble\let\setcounter\@gobbletwo
  \globaldefs\@ne \let\c@loldepth\@ne
  \newlistof{listings}{lol}{\lstlistlistingname}
\endgroup
\let\l@lstlisting\l@listings
\makeatother

然后，使用一些tocloft命令：

\setlength{\cftlistingsindent}{1.5em}
\renewcommand*{\cftlistingspresnum}{\lstlistingname~}
\settowidth{\cftlistingsnumwidth}{\cftlistingspresnum}
\addtolength{\cftlistingsnumwidth}{2.3em}
\renewcommand{\cftlistingsaftersnum}{:}

最后，删除前面提到的代码，也就是修改你的 MWE 为

\documentclass[12pt, a4paper, oneside]{scrartcl}

\usepackage[utf8]{inputenc}
\usepackage{textcomp}
\usepackage{tocloft}
\usepackage[ngerman]{babel}
\usepackage[hidelinks=true]{hyperref}
\usepackage[final]{pdfpages}

\definecolor{grey}{gray}{0.9}

\usepackage{listings}
\renewcommand\lstlistingname{Code}
\lstloadlanguages{Ruby}
\lstset{%
basicstyle=\small\ttfamily\color{black},
commentstyle = \ttfamily\color{red},
keywordstyle=\ttfamily\color{blue},
stringstyle=\color{orange},
backgroundcolor=\color{grey},
columns=fullflexible}

\usepackage{color}
\usepackage{xcolor}

\usepackage{caption}
\DeclareCaptionFont{white}{\color{white}}
\DeclareCaptionFormat{listing}{\colorbox{gray}{\parbox{\textwidth}{#1#2#3}}}
\captionsetup[lstlisting]{format=listing,labelfont=white,textfont=white}

\makeatletter
\begingroup\let\newcounter\@gobble\let\setcounter\@gobbletwo
  \globaldefs\@ne \let\c@loldepth\@ne
  \newlistof{listings}{lol}{\lstlistlistingname}
\endgroup
\let\l@lstlisting\l@listings
\makeatother

\setlength{\cftlistingsindent}{1.5em}
\renewcommand*{\cftlistingspresnum}{\lstlistingname~}
\settowidth{\cftlistingsnumwidth}{\cftlistingspresnum}
\addtolength{\cftlistingsnumwidth}{2.3em}
\renewcommand{\cftlistingsaftersnum}{:}

\usepackage{geometry}
\geometry{a4paper, top=25mm, left=25mm, right=25mm, bottom=20mm, headsep=10mm, footskip=12mm}

\begin{document}

 \renewcommand\lstlistlistingname{Codelisting}
 \addcontentsline{toc}{section}{Codelisting}
 \lstlistoflistings
 \newpage

  \begin{lstlisting}[language=Ruby, caption=StatusCalculator Initialize, label=initialize]
  def initialize(project_id)
    @project = Project.find(project_id)
  end
  \end{lstlisting}

\end{document}
