创建简单框架

\separate我希望我的部分文本被“框起来”。到目前为止，我已经通过以下 MWE 中的命令生成了水平线：

\documentclass{article}
\newcommand\separate{\medskip\hrule\medskip} % nice page-long underscores
\begin{document}
Here is introductory text.
\separate
Here is text in the frame.
\separate
Here is concluding text.
\end{document}

两个问题：

1) 如何使水平线稍微延伸到外边缘？（以便它仅超出其框架的文本0.2英寸左右......）

2) 如何添加代码来生成水平线和垂直线？我希望“框架”最终看起来像这样：

 ----------------------------

                            |
----------------------------

编辑：

更具体地说，我希望它能与环境一起工作fullwidth，如以下（更新的）MWE：

\documentclass{article}
\usepackage{fullwidth}
\newcommand\separate{\medskip\hrule\medskip} % nice page-long underscores
\begin{document}

Here is introductory text.

\begin{fullwidth}[outermargin = -4cm, width = \linewidth + 4cm]
\separate
Here is text in the frame
\separate
\end{fullwidth}

Here is concluding text.
\end{document}

非 TikZ 解决方案

\documentclass{article}
\usepackage{xcolor,graphicx,lipsum}
\parindent0pt
\begin{document}
\def\boxit #1{%
    \parindent0pt
    \leavevmode
    \hbox{\vbox{%
     \hrule
      %
        \vbox to 0pt{\vrule height50pt width1pt}
            \leftskip10pt\rightskip10pt
            \vskip10pt%  
            #1%
   \vskip-50pt\vbox to 0pt{\hskip\dimexpr\hsize-10pt\relax\vrule height50pt width1pt}
    \vskip50pt
    \hrule
   }%
}}
\boxit{\lipsum[2]}
\end{document}

要使用全宽包，需要进行一些小的调整；带有键值接口的完整代码有点长，所以我将其粘贴在https://gist.github.com/1971055。

我很确定 TikZ 会在这里有所作为，因为它在这些方面更加熟练和具有装饰性。但是，可以使用规则组合来获得此布局。我决定使用环境而不是两个单独的宏，因为它似乎更合适 - 环境允许开始和结束声明。

\documentclass{article}
\usepackage{showframe}% http://ctan.org/pkg/showframe
\newenvironment{separateA}
  {\par\nobreak%
   \noindent\smash{\makebox[\textwidth]{%
     \rule[-.25\baselineskip]{.4pt}{\dimexpr.25\baselineskip+.4pt}% left hang
     \rule{\dimexpr\textwidth+.4in-.8pt}{.4pt}% horizontal rule
     \rule[-.25\baselineskip]{.4pt}{\dimexpr.25\baselineskip+.4pt}% right hang
   }}}
  {\par\nobreak%
   \noindent\smash{\makebox[\textwidth]{%
     \rule[.5\baselineskip]{.4pt}{.25\baselineskip}% left hung
     \rule[.5\baselineskip]{\dimexpr\textwidth+.4in-.8pt}{.4pt}% horizontal rule
     \rule[.5\baselineskip]{.4pt}{.25\baselineskip}% right hung
   }}}
\newenvironment{separateB}
  {\par\nobreak%
   \noindent\smash{\makebox[\textwidth]{%
     \rule[-.25\baselineskip]{.4pt}{\dimexpr.25\baselineskip+.4pt}% left hang
     \rule{\dimexpr\textwidth+.4in-.4pt}{.4pt}% horizontal rule
     %\rule[-.25\baselineskip]{.4pt}{\dimexpr.25\baselineskip+.4pt}% right hang
   }}}
  {\par\nobreak%
   \noindent\smash{\makebox[\textwidth]{%
     %\rule[.5\baselineskip]{.4pt}{.25\baselineskip}% left hung
     \rule[.5\baselineskip]{\dimexpr\textwidth+.4in-.4pt}{.4pt}% horizontal rule
     \rule[.5\baselineskip]{.4pt}{.25\baselineskip}% right hung
   }}}
\newenvironment{separateC}
  {\par\nobreak%
   \noindent\smash{\makebox[\textwidth]{%
     %\rule[-.25\baselineskip]{.4pt}{\dimexpr.25\baselineskip+.4pt}% left hang
     \rule{\dimexpr\textwidth+.4in-.4pt}{.4pt}% horizontal rule
     \rule[-.25\baselineskip]{.4pt}{\dimexpr.25\baselineskip+.4pt}% right hang
   }}}
  {\par\nobreak%
   \noindent\smash{\makebox[\textwidth]{%
     \rule[.5\baselineskip]{.4pt}{.25\baselineskip}% left hung
     \rule[.5\baselineskip]{\dimexpr\textwidth+.4in-.4pt}{.4pt}% horizontal rule
     %\rule[.5\baselineskip]{.4pt}{.25\baselineskip}% right hung
   }}}
\begin{document}
Some fully boxed text, using \verb|separateA|:

\begin{separateA}
Here is text in the frame.
\end{separateA}

Some partially boxed text (left and right), using \verb|separateB|:

\begin{separateB}
Here is text in the frame.
\end{separateB}

Some partially boxed text (right and left), using \verb|separateC|:

\begin{separateC}
Here is text in the frame.
\end{separateC}

Here is concluding text.
\end{document}

为了区别起见，上述 MWE 提供了三种环境（尽管它们实际上完全相同）：separateA打印“完全装箱”的块，同时separateB打印“部分装箱”的块（左右）以及separateC“部分装箱”的块（从右到左）。注意使水平分隔正好\textblock+.4in宽，恰好悬在.2in两边的边缘上。

构建一个单一环境（比如说）来执行此操作会很容易separate，并使用可选参数来控制挂起/挂起的位置。

showframe用于突出显示文本块边界，并指示和强调文本边缘外的悬垂部分。

\documentclass{article}
\newcommand\separate[1][]{%
  \par\noindent
  \ifx\relax#1\relax
    \makebox(0,0){\rule[-2\normalbaselineskip]{\fboxrule}{\normalbaselineskip}}%
    \kern-0.5\fboxrule\rule{1.1\textwidth}{\fboxrule}%
  \else  
    \rule{1.1\textwidth}{\fboxrule}%
    \makebox(0,0){\rule[\normalbaselineskip]{\fboxrule}{\normalbaselineskip}}%
  \fi\par}
\begin{document}
Here is introductory text.
\separate
Here is text in the frame.
\separate[up]
Here is concluding text.
\end{document}

这是 Metapost 的解决方案（在 ConTeXt 中）。我定义了一个MP背景在 metapost 中，可以将其插入任何接受参数的 ConTeXt 对象background。

\startuniqueMPgraphic {splitframe}
  newpath topborder, bottomborder;
  newpath BackgroundBox;
  BackgroundBox := OverlayBox enlarged (0.2cm);

  bottomborder = point 0 of BackgroundBox -- point 1 of BackgroundBox 
              -- point 1.2 of BackgroundBox ;

  topborder    = point 2 of BackgroundBox -- point 3 of BackgroundBox 
              -- point 3.2 of BackgroundBox ;

  draw bottomborder withpen pencircle scaled OverlayLineWidth
       withcolor OverlayLineColor ;

  draw topborder withpen pencircle scaled OverlayLineWidth
       withcolor OverlayLineColor ;

  setbounds currentpicture to OverlayBox ;

\stopuniqueMPgraphic

\defineoverlay [splitframe] [\uniqueMPgraphic{splitframe}]

举例来说，考虑为侧边浮动和文本背景添加框架。

\definebackground
  [splitframe]
  [background=splitframe,
   rulethickness=1.5pt,
   framecolor=blue,
   width=broad,
   frame=off]

\starttext
\placefigure[right,none]{}
  {\externalfigure[cow][background=splitframe,width=0.3\textwidth,framecolor=red]}
\startsplitframe
  \input tufte
\stopsplitframe
\stoptext
