列表：背景框的宽度

列表：背景框的宽度

我正在尝试修改我的列表环境，使列表的背景颜色扩展到整个页面的宽度。这样就不留白边了。

这可能吗？

我尝试做了一些研究，但似乎无法找到解决方案。

这是我当前的列表环境：

\documentclass{article}
\usepackage{color}
\usepackage{listings}

\definecolor{MyLightGray}{RGB}{200, 200,200}

\lstdefinelanguage{turtle}
{
    columns=fullflexible,
    keywordstyle=\color{red},
    morekeywords={@prefix,@base,@forSome,@forAll,@keywords},
    morecomment=[l]{\#},
    tabsize=4, 
    alsoletter={-?}, % allowed in names
    morecomment=[s][\color{blue}]{<}{>},
    basicstyle=\ttfamily\color{black}, 
    %numberstyle=\color{black},
    morestring=[b][\color{black}]\",    
    backgroundcolor=\color{MyLightGray},
}
\begin{document}

\begin{lstlisting}[language=turtle, captionpos=t]
@prefix something:              <http://example.org/something/> 

something:subject       something:predicate     something:object .
\end{lstlisting}
\end{document}

这是输出：

我不希望代码显示在文本宽度之外，只希望列表的背景窗格展开。

任何帮助都值得赞赏

快速补充。我注意到我的 pdf 阅读器上的代码行之间有小白线。它们在打印时不显示，但这可能是由于浅灰色背景。这只是视觉错觉还是当我选择较暗的背景颜色时它们会更突出。

我的答案是使用该tcolorbox包来帮助解决装箱问题。请注意，您应该使用该包的当前版本3.12 (2014/07/29)，即您可能需要先更新。

版本 1：

解决方案的基本思路是将列表用tcolorbox放大到页面边缘的框起来。在这里，我使用了 5cm 的粗暴放大，而没有对实际边距进行微调。但是，如果您的实际边距不大于 5cm，那么这也适用于双面文档。

\documentclass{article}
\usepackage{color}
\usepackage[listings,skins,breakable,xparse]{tcolorbox}

\definecolor{MyLightGray}{RGB}{200, 200,200}

\lstdefinelanguage{turtle}
{
    columns=fullflexible,
    keywordstyle=\color{red},
    morekeywords={@prefix,@base,@forSome,@forAll,@keywords},
    morecomment=[l]{\#},
    tabsize=4,
    alsoletter={-?}, % allowed in names
    morecomment=[s][\color{blue}]{<}{>},
    basicstyle=\ttfamily\color{black},
    %numberstyle=\color{black},
    morestring=[b][\color{black}]\",
    backgroundcolor=\color{MyLightGray},
}

\NewTCBListing{widelisting}{ O{} O{} }{
  listing only,breakable,listing options={#1,aboveskip=0pt,belowskip=0pt},
  enhanced,sharp corners,size=tight,boxrule=0pt,frame hidden,
  width=\textwidth+10cm,
  enlarge left by=-5cm,left=5cm,
  enlarge right by=-5cm,right=5cm,
  colback=MyLightGray,
  #2 }


\begin{document}

\begin{lstlisting}[language=turtle, captionpos=t]
@prefix something:              <http://example.org/something/>

something:subject       something:predicate     something:object .
\end{lstlisting}


\begin{widelisting}[language=turtle]
@prefix something:              <http://example.org/something/>

something:subject       something:predicate     something:object .
\end{widelisting}

\end{document}

您将发现，使用预览器查看时，新环境widelisting也没有细小的白线。 在此处输入图片描述

版本 2：

如果您想要为列表添加标题或标题，则必须进行一些修改。为了模仿原始的lstlisting，可以使用以下内容，它与普通的列表：

\documentclass{article}
\usepackage{color}
\usepackage[listings,skins,breakable,xparse]{tcolorbox}

\definecolor{MyLightGray}{RGB}{200, 200,200}

\lstdefinelanguage{turtle}
{
    columns=fullflexible,
    keywordstyle=\color{red},
    morekeywords={@prefix,@base,@forSome,@forAll,@keywords},
    morecomment=[l]{\#},
    tabsize=4,
    alsoletter={-?}, % allowed in names
    morecomment=[s][\color{blue}]{<}{>},
    basicstyle=\ttfamily\color{black},
    %numberstyle=\color{black},
    morestring=[b][\color{black}]\",
    backgroundcolor=\color{MyLightGray},
}

\NewTCBListing[use counter=lstlisting,list inside=lol,list type=lstlisting]{widelistingtitled}{ O{} O{} m }{
  listing only,breakable,listing options={#1,aboveskip=0pt,belowskip=0pt},
  enhanced,sharp corners,size=tight,boxrule=0pt,frame hidden,
  width=\textwidth+10cm,
  enlarge left by=-5cm,left=5cm,
  enlarge right by=-5cm,right=5cm,
  colback=MyLightGray,
  title=Listing~\thetcbcounter:~#3,
  list entry={\protect\numberline{\thetcbcounter}#3},
  attach boxed title to top center,coltitle=black,
  boxed title style={width=textwidth,empty},
  #2 }


\begin{document}

\lstlistoflistings

\begin{lstlisting}[language=turtle, captionpos=t, caption=Original Example]
@prefix something:              <http://example.org/something/>

something:subject       something:predicate     something:object .
\end{lstlisting}

\begin{widelistingtitled}[language=turtle]{Wide Listing with Title}
@prefix something:              <http://example.org/something/>

something:subject       something:predicate     something:object .
\end{widelistingtitled}

\end{document}

版本 3：

作为一种变体，我在这里使用了一些颜色和附加线条：

\documentclass{article}
\usepackage{color}
\usepackage[listings,skins,breakable,xparse]{tcolorbox}

\definecolor{MyLightGray}{RGB}{200, 200,200}

\lstdefinelanguage{turtle}
{
    columns=fullflexible,
    keywordstyle=\color{red},
    morekeywords={@prefix,@base,@forSome,@forAll,@keywords},
    morecomment=[l]{\#},
    tabsize=4,
    alsoletter={-?}, % allowed in names
    morecomment=[s][\color{blue}]{<}{>},
    basicstyle=\ttfamily\color{black},
    %numberstyle=\color{black},
    morestring=[b][\color{black}]\",
    backgroundcolor=\color{MyLightGray},
}

\NewTCBListing[use counter=lstlisting,list inside=lol,list type=lstlisting]{widelistingtitled}{ O{} O{} m }{
  listing only,breakable,listing options={#1,aboveskip=0pt,belowskip=0pt},
  enhanced,sharp corners,size=tight,top=1mm,bottom=1mm,boxrule=0.5mm,
  colframe=MyLightGray!50!blue,
  width=\textwidth+10cm,
  enlarge left by=-5cm,left=5cm,
  enlarge right by=-5cm,right=5cm,
  colback=MyLightGray,
  title=Listing~\thetcbcounter:~#3,
  list entry={\protect\numberline{\thetcbcounter}#3},
  attach boxed title to top center={yshift=-0.4mm},coltitle=black,
  boxed title style={width=textwidth,colback=blue!15!white,sharp corners=south},
  #2 }


\begin{document}

\lstlistoflistings

\begin{lstlisting}[language=turtle, captionpos=t, caption=Original Example]
@prefix something:              <http://example.org/something/>

something:subject       something:predicate     something:object .
\end{lstlisting}

\begin{widelistingtitled}[language=turtle]{Wide Listing with Title}
@prefix something:              <http://example.org/something/>

something:subject       something:predicate     something:object .
\end{widelistingtitled}

\end{document}
