使用 \ifbool{}{} 检查标志后如何使用逐字或动词？

Question

我不知道是否verb允许verbatim进入\ifbool检查。这使得检查非常有限。

我需要根据标志生成代码。要生成的代码恰好有一小部分使用了\verb。因此我收到错误。

我在看文档但etoolbox目前还没有看到任何可以帮助我解决这个问题的东西。

有没有办法使用\verb如下

\documentclass[11pt]{scrbook}%
\IfFileExists{luatex85.sty}{\usepackage{luatex85}}{}
\usepackage{etoolbox} 
\newbool{private}
\setbool{private}{true}

\begin{document}

\ifbool{private}
{
This is \verb|test|  %how to make this work?
}%
{
This is the other case
}
\end{document}

感谢以下答案。我必须使用，\newbool{private}\setbool{private}{true}因为我已经使用复杂的预处理设置了这些（我在构建期间从文件中读取此标志等...并且我不想更改所有这些代码，因为它是自动化的），但在答案的帮助下，我找到了一种解决方法，它允许我使用当前的布尔值并用于\newif绕过这个限制。这是最终的代码

\documentclass[11pt]{scrbook}%
\usepackage{etoolbox} 

\newbool{private}
\setbool{private}{true}%in actual application, this only set at compile time
              %from reading a file based on makefile command line
              %setting. So it is not hardcoded in the Latex file as shown
              %in this MWE. This is just an example.
\newif\ifprivate

\ifbool{private}{\privatetrue}{\privatefalse}

\begin{document}

\ifprivate
  This is \verb|test|  
\else 
  This is the other case
\fi 

\end{document}

Answer 1

\ifbool是宏，因此\verb在其参数中是不可能的。

我认为标准\newif方法要简单得多（并且有效），因为不涉及任何争论：

\documentclass[11pt]{scrbook}%
\IfFileExists{luatex85.sty}{\usepackage{luatex85}}{}
%\usepackage{etoolbox} 
%\newbool{private}
%\setbool{private}{true}

\newif\ifprivate
\privatetrue
\begin{document}

\ifprivate
  This is \verb|test|  %how to make this work?
\else
This is the other case
\fi

\privatefalse% Now the other way round. 

\ifprivate
  This is \verb|test|  %how to make this work?
\else
This is the other case
\fi

\end{document}

编辑：是的，我知道，这个问题是关于的etoolbox，但我认为这更容易（或者根本不可能）并且它不需要其他包。

Answer 2

如果您事先知道要逐字排版的内容，verbbox环境可以提供帮助。

\documentclass[11pt]{scrbook}%
\IfFileExists{luatex85.sty}{\usepackage{luatex85}}{}
\usepackage{etoolbox} 
\newbool{private}
\setbool{private}{true}
\usepackage{verbatimbox}
\begin{document}
\begin{myverbbox}{\caseA}t&st\end{myverbbox}
\begin{myverbbox}{\caseB}Mi#tak^e\end{myverbbox}
\def\mytest{\ifbool{private}
{
This is \caseA  %how to make this work?
}%
{
This is \caseB
}}
\mytest\par
\privatefalse
\mytest
\end{document}

注意，myverbbox可以采用可选参数来调节逐字框。因此，如果将其定义为

\begin{myverbbox}[\scshape]{\caseA}T&st\end{myverbbox}
\begin{myverbbox}[\itshape]{\caseB}Mi#tak^e\end{myverbbox}

结果是
