列表：添加垂直填充而不滥用框架

我对显示的列表进行了以下设置：

在此处输入图片描述

\documentclass[a4paper]{article}

\pagestyle{empty}

\usepackage{listings,xcolor,lipsum}

\lstset{
    backgroundcolor = \color{yellow},
    basicstyle = \ttfamily,
    columns = fullflexible,
    tabsize = 4,
    frame = leftline,
    framesep = 0pt,
    framexleftmargin = 3pt,
    framerule = 2pt,
    rulecolor = \color{green!50!black},
    xrightmargin = -3pt,
    numbers = left,
}

\begin{document}

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum fermentum aliquam ipsum at consequat. Nam id aliquam ex, a auctor augue laoreet.
\begin{lstlisting}
Hello, world!

\bye
\end{lstlisting}
\noindent\lipsum*[4]

\end{document}

具体来说，我有：

  • tt字体；
  • 背景颜色;
  • 沿着列表左边距的装饰线；
  • 背景突出到页边距。

现在我想向列表添加顶部和底部填充，如下所示：

标准方法是在列表周围添加黄色边框。但是，我似乎无法做到这一点，因为我不能有两个边框：一个黄色，一个绿色。那么我该怎么做呢？

我正在升级我的verbatimbox软件包，以提供一些代码（而非语法）突出显示工具（请参阅下面的软件包修订草案）。我能够在一定程度上实现您添加垂直缓冲区的目标，但有一个限制。由于黄色色域是为每条逐字行绘制的，如果它垂直向上延伸得太远，它会覆盖前一条逐字行的下行部分。因此，在这个例子中，我发现我只能将它设置\vbxcolorfieldoverlap为（）1.4pt 大，而不会开始重叠。也许这对您的口味来说已经足够了。这个参数最初被引入为一个小的正值，以防止在连续的逐字行之间偶尔出现细白线，但我发现在这种情况下我可以将其放大以产生顶部/底部颜色缓冲区。

\documentclass{article}
\usepackage{verbatimbox,xcolor}
\def\vbxnumberformat{\arabic{VerbboxLineNo}\kern1ex\textcolor{green!50!black}{%
  \rule[\dimexpr-\dp\strutbox-\vbxcolorfieldoverlap\relax]{2pt}{%
        \dimexpr\baselineskip+2\vbxcolorfieldoverlap\relax}}}
\def\vbxcodestyle{\ttfamily\normalsize\strut}
\def\vbxnumberstyle{\rmfamily\normalsize}
\setlength\vbxnumbergap{0pt}
\setvbxfieldwidth[3pt]{\dimexpr\textwidth+6pt\relax}
\VerbCodeIndent=-3pt\relax
\vbxContinueLineNoAfter
\def\vbxformat{%
  \vbxnum%
  \vbxfieldcolor[yellow]%
  \hspace{\vbxleftfieldwidth}%
  \vbxcodestyle%
}
\begin{document}
\setlength\vbxcolorfieldoverlap{1.4pt}%
This has 1.4pt vertical buffer (any more overlaps prior verbatim line):
\begin{verbnobox}[\vbxformat]
Hello World!
    this is a y descender
bye
\end{verbnobox}
\setlength\vbxcolorfieldoverlap{0pt}%
This has no vertical buffer:
\begin{verbnobox}[\vbxformat]
Hello World! continued
    this is a y descender
bye
\end{verbnobox}
Donec vehicula augue eu neque. Pellentesque habitant morbi tristique senectus

这是我的 V4.00 草稿版本verbatimbox.sty，与 MWE 一起使用。

\ProvidesPackage{verbatimbox}
        [2015/03/25 \verbatimboxVersionNumber
Routines for placing verbatim text into boxes, useful in places where
the verbatim environment is inaccessible.  Secondarily, for adding

% This work has the LPPL maintenance status `maintained'.
%
% The Current Maintainer of this work is Steven B. Segletes.
%
% verbatimbox.sty is based on boxedverbatim environment found
% in moreverb.sty.
%
% An enabling routine, \addvbuffer[]{} shares some functional
% similarities to \raisebox, but it is not the same.
%
% 2.01 -Added LPPL License info to package
% 3.0  -Added myverbbox environment
%      -Corrected problem when no optional arguments are passed to
%         verbbox environment
%      -Added optional arguments to \addvbuffer
%      -Fixed \verbfilebox so that it restored \verbatim@processline
%      -Produced real documentation
% 3.01 -renamed \macro@name so as not to conflict with (I think) ltxdoc
%       package
% 3.1  -Corrected default argument to \addvbuffer so that it wouldn't
%       break.  Also, gave better guidance in documentation to use
%       of optional argument to \addvbuffer
%      -Added verbnobox environment and \verbfilenobox macro
%      -Improved documentation showing line-specific optional arguments
% 3.11 -Eliminated the use of the stringstrings package, which resets
%       the definition of \|
% 3.12 -Corrected bug introduced in V3.11, which occured with [t] 
%       option to \theverbbox
%      -When using two lengths in \addvbuffer optional argument,
%       they MUST be individually in {}, rather than "~" or "\ " between
% 3.13 -Corrected residual bug from V3.11, when \addvbuffer called
%       without an optional argument.
% 4.00 -Added cverbbox and mycverbbox environments for color
%      -Added host of code highlighting routines.

这个想法是，您使用verbatimbox宏的可选参数来“编程”逐字的外观。

因此，verbatimbox当将这种格式应用于给定的逐字内容时，可能会产生以下结果（这个例子有些夸张，但我只是想塞入一些特性来展示它可以调整的事物类型）：

\def\vbxformat{%
 \setvbxfieldwidth[.23\linewidth]{.74\linewidth}%
 \vbxtitle{%
    Verbbox \thenextvbxcount. This is the title\\ for my code on\\\today{}}%
  \invbxline{1}{%
    \vbxfieldcolor[green!8]\vbxnumcolor{green!75!black}%
  }{%
    \invbxlines{3}{4}{%
      \vbxfieldcolor\vbxnumstyle{\color{red}\normalsize$\rightarrow$}%
    }{%
      \invbxlines{8}{18}{%
        \vbxfieldcolor[blue!12!gray!15]\vbxnumcolor{black!20}%
     }{%
      \vbxfieldcolor[cyan!3]\vbxnum%
     }%
    }%
  }%
  \invbxline{11}{\vbxcommentwidth{.22\vbxfieldwidth}%
    \vbxcomment{I am drawing attention to ``Hello World''}}{}%
  \invbxline{15}{\vbxcommentwidth[-.3\vbxfieldwidth]{.22\vbxfieldwidth}%
    \vbxcomment[\normalsize]{I like \LaTeX{}}}{}%
  \vbxcodestyle\,%
}

这完全是一次黑客攻击，涉及在环境周围添加\beforerule和。\afterrule

\documentclass[a4paper]{article}

\pagestyle{empty}

\usepackage{listings,xcolor,lipsum}

\lstset{
    backgroundcolor = \color{yellow},
    basicstyle = \ttfamily,
    columns = fullflexible,
    tabsize = 4,
    frame = leftline,
    framesep = 0pt,
    framexleftmargin = 3pt,
    framerule = 2pt,
    rulecolor = \color{green!50!black},
    xrightmargin = -3pt,
    numbers = left,
}
\def\beforerule{%
  \par\noindent\makebox[\textwidth]{%
  \llap{\color{green!50!black}\rule{2pt}{3pt}}%
  \color{yellow}\rule{\dimexpr6pt+\textwidth}{3pt}}%
  \par\vspace*{-10pt}%
}
\def\afterrule{%
  \vspace*{-14.5pt}\noindent\makebox[\textwidth]{%
  \llap{\color{green!50!black}\rule[-3pt]{2pt}{3pt}}%
  \color{yellow}\rule[-3pt]{\dimexpr6pt+\textwidth}{3pt}}%
  \par\vspace{6pt}%
}

\begin{document}

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum fermentum aliquam ipsum at consequat. Nam id aliquam ex, a auctor augue laoreet.

\beforerule
\begin{lstlisting}
Hello, world!

\end{lstlisting}
\afterrule

\noindent\lipsum*[4]
