如何制作打印逐字文本的宏？

Question 1

该fancyvrb包允许您定义自己的环境。如果您使用它，您只需更改定义：

\documentclass[]{article}

\usepackage{fancyvrb}
\usepackage{fvextra}

\DefineVerbatimEnvironment{MyVerbatim}{Verbatim}{breaklines=true,numbers=left,breakafter=\},breakbefore=\\}

\begin{document}

\begin{MyVerbatim}
text text text text text \macro{text}
\end{MyVerbatim}

\end{document}

Question 2

我无法推荐使用具有无界参数语法的宏来生成多行逐字材料：

处理源代码缩进的问题会引起混淆，因为源代码中的逐字缩进空间被标记化，因此在输出中显示为水平空间/可见空间。

为了展示一些问题/怪异之处，下面的示例提供了一个宏\bigvrb-showspaces=true应用该选项，以便您可以更好地看到旨在缩进的空格的处理，只是为了使源代码更具可读性：

\RequirePackage{xparse}
\documentclass[a4paper]{article}

\usepackage{fancyvrb}
\usepackage{fvextra}

\NewDocumentCommand\bigvrb{}{%
  \begingroup
  \catcode`\^^I=12 %
  %\endlinechar=`\^^M
  \newlinechar=\endlinechar
  \innerbigvrb
}%
\begingroup
\catcode`\^^A=14\relax
\catcode`\%=12\relax
\catcode`\{=12\relax
\catcode`\}=12\relax
\catcode`\(=1\relax
\catcode`\)=2\relax
\catcode`\/=0\relax
\catcode`\\=12\relax
/catcode`/^^M=12/relax^^A
/csname @firstofone/endcsname(^^A
  /endgroup^^A
  /NewDocumentCommand/innerbigvrb(+v)(^^A
    /scantokens(^^A
      \endgroup^^A
      \begin{Verbatim}[showspaces=true, breaklines=true,numbers=left,breakafter=\},breakbefore=\\]^^M^^A
      #1^^M^^A
      \end{Verbatim}^^M%^^A
    )^^A
  )^^A
)%

\pagestyle{empty}
\parindent=0ex
\parskip=.25\baselineskip

\begin{document}
\enlargethispage{9cm}\vspace*{-4.5cm}%

\noindent\hrulefill

This looks okay:

\bigvrb{ABC
DEF}

\noindent\hrulefill

This has a visible comment-char and the spaces for indenting the code are visible also:

\bigvrb{%
  ABC%
  DEF%
}
\noindent\hrulefill

The spaces for indenting the code are visible. Besides this you have four
linebreaks \emph{inside} the verbatim-argument---the linebreak before the
first line (\verb*|  ABC|) and the linebreak after the last line
(\verb*|  DEF|) each yields an empty line:

\bigvrb{
  ABC
  DEF
}

\noindent\hrulefill

Even more spaces are used for indenting the code. They all are visible:

\begin{itemize}
\item Some text of an item of an \verb|itemize|-environment.
      That item also contains a \verb|\bigvrb|-command whose
      result is here:
      \bigvrb{ABC
              DEF}
\end{itemize}

\noindent\hrulefill

Now let's have fun creating two \verb|Verbatim|-environments in a weird way, keeping in mind that
curly braces must be balanced with \verb|\bigvrb|'s argument if not using delimiter-syntax:

\let\MyClosebrace=\}
\bigvrb{First environment
\end{Verbatim}

\begin{Verbatim}[showspaces=true, breaklines=true, numbers=left, breakafter=\MyClosebrace, breakbefore=\\]
Second environment}

\noindent\hrulefill

Now let's have fun creating two \verb|Verbatim|-environments in a weird way,
using delimiter-syntax---as verbatim-arg-delimiter \verb|>| is chosen:

\bigvrb>First environment
\end{Verbatim}

\begin{Verbatim}[showspaces=true, breaklines=true, numbers=left, breakafter=\}, breakbefore=\\]
Second environment>


\noindent\hrulefill

\textbf{Summa summarum:}

Undelimited-argument-syntax with multiline-verbatim-material is
confusing as 
\begin{itemize}
\item you cannot have the usual code-indentation and linebreaking.
\item you cannot easily use the command \verb|\bigverb|
for verbatimized typesetting of the line \verb|\end{Verbatim}|.
\item you may need to take care of braces being balanced in
\verb|\bigvrb|'s argument if you don't use delimiter-syntax.
\end{itemize}

\end{document}

当然\bigvrb，上面的例子的目的是通过在（暂时）切换到 verbatim-catcode-régime 后读取和标记 .tex-input 来获取其参数。

因此\bigvrb在获得其论据的情况下不起作用

通过将其作为宏定义的一部分传递，该宏定义在非逐字猫码制度下被标记化
通过将其从另一个宏传递，在执行该宏期间，该参数在非逐字 catcode 机制下被标记化
\the当寄存器的内容在非逐字 catcode 机制下被标记化时，通过 -expansion 将其从标记寄存器传递过来
ETC。

将其作为移动论证的组成部分可能会产生意想不到的效果。

根据经验法则，您可以\bigvrb在文档文本中使用它，但不能在宏定义/其他宏的参数中使用它。因此它的用途非常有限。
