如何获取输出文档文件中实际输出的整个文本？

Question

考虑以下 LaTeX 文档

\documentclass{article}
\usepackage{enumerate}
\begin{document}

\begin{enumerate}[(a)]

\item Here is the 1st line.
\item Here is the 2nd line.

\end{enumerate}

\end{document}

它给出以下输出

（a）这是第一行。
（b）这是第二行。

但是，我想获得以下输出

\documentclass{article}
\usepackage{enumerate}
\begin{document}

\begin{enumerate}[(a)]

\item Here is the 1st line.                   (a)  Here is the 1st line.
\item Here is the 2nd line.                   (b) Here is the 2nd line            

\end{enumerate}

\end{document}

也就是说，左侧的列将包含整个文本，而右侧的列将包含 TeX 代码的原始输出。有什么办法可以做到这一点吗？

Answer 1

这是您的 MWE showexpl：

\documentclass{article}
\usepackage{enumerate}
\usepackage[final]{showexpl}

\begin{document}

\begin{LTXexample}
\begin{enumerate}[(a)]
\item Here is the 1st line.
\item Here is the 2nd line.
\end{enumerate}
\end{LTXexample}

Another possibility in Listing~\ref{ex:test}:

\begin{LTXexample}[pos=r,rframe={},caption={Test},label=ex:test]
\begin{enumerate}[(a)]
\item Here is the 1st line.
\item Here is the 2nd line.
\end{enumerate}
\end{LTXexample}

Another possibility is:

\begin{LTXexample}[pos=r,rframe=single,numbers=none,basicstyle=\ttfamily\small,]
\begin{enumerate}[(a)]
\item Here is the 1st line.
\item Here is the 2nd line.
\end{enumerate}
\end{LTXexample}

Original environment in document:
\begin{enumerate}[(a)]
\item Here is the 1st line.
\item Here is the 2nd line.
\end{enumerate}

\end{document}

\documentclass{article}
\usepackage{verbatim}
\usepackage{enumerate}

\begin{document}

\noindent
\begin{minipage}{.42\textwidth}
\verbatiminput{ex1.tex}
\end{minipage}
\hfill
\vrule
\hfill
\begin{minipage}{.42\textwidth}
\def\documentclass#1{}
\def\usepackage#1{}
\renewenvironment{document}{}{}
\input{ex1.tex}
\end{minipage}

\end{document}

ex1.tex你的例子在哪里？
