替换 \label 内的 #

tag-icon • tag-icon characters
替换 \label 内的 #

我们目前在文档中使用唯一 ID，可以通过添加一个或多个标签来扩展。标签始终以井号开头，例如 MY.REQ.ID.42#TAG1#TAG2

以下代码是我们用来生成“美观”需求的宏的一部分：

\textbf{#1}\def\@currentlabel{#1}\label{req:#1}

连同列出所有要求的列表，\label 中的 # 字符存在问题。因此，我正在寻找一种方法来摆脱该字符，方法是将其替换为其他字符，例如“..”或“HASH”。

任何想法都将不胜感激...

谢谢，再见，aronadaal

答案1

在您的示例中，您使用了\#参数\req。如果这不是问题，您可以在生成标签时简单地在本地重新定义其含义。例如，您可以用\label{req:#1}替换{\def\#{REPLACEMENT}\xdef\lbl{req:#1}}\label{\lbl}。

例子：

\documentclass[a4paper]{scrartcl}
\usepackage[left=2cm,right=2cm,top=2.5cm,bottom=2cm]{geometry}
\setlength\parindent{0pt}

\makeatletter
\newcommand{\hashtag}{\#}
\newcommand{\req}[2]{%

\begingroup%
\textbf{#1}{\def\@currentlabel{#1}{\def\#{::}\xdef\lbl{req:#1}}\label{\lbl}}~#2\newline%
\endgroup%
\addcontentsline{lor}{requirement}{#1}%
} %

\DeclareNewTOC[%
type=requirement, %
types=requirements, %
name=Anforderung, %
listname={List of Requirements} %
]{lor}
\setuptoc{lor}{chapteratlist}

\begin{document}
\section{Test}
\req{MY.REQ.ID.42}{Lorem ipsum dolor sit amet,...}%
\req{MY.REQ.ID.42\#WORKING}{this requirement is broken,...}

Please have a look at \ref{req:MY.REQ.ID.42} on page~\pageref{req:MY.REQ.ID.42}

Please have a look at \ref{req:MY.REQ.ID.42::WORKING} on page~\pageref{req:MY.REQ.ID.42::WORKING}

因为到现在还没有简单的解决方案，所以我把它放在：

\protected\edef\#{\string#}

答案3

好吧，这确实有效，但这是一个非常卑鄙的伎俩。我希望我稍后能设法注释代码。有一件事是肯定的：它极其脆弱（并且不可能增强）。

\documentclass[a4paper]{scrartcl}
\usepackage[left=2cm,right=2cm,top=2.5cm,bottom=2cm]{geometry}
\setlength\parindent{0pt}

\makeatletter
\def\req#1#2{%
  \begingroup
    \catcode`\#=13
    \makehashexcl
    \edef\aron@do@label{\noexpand\label{req:\scantokens{#1\noexpand}}}%
    \makehashhash
    {\bfseries\scantokens{#1\noexpand}}%
    \edef\@currentlabel{\scantokens{#1\noexpand}}%
    \aron@do@label
    ~#2\newline
    \edef\aron@do@lor{\noexpand\addcontentsline{lor}{requirement}{\scantokens{#1\noexpand}}}%
    \aron@do@lor
  \endgroup%
}

\def\refreq#1#2{%
  \begingroup
    \catcode`\#=13
    \makehashexcl
    \edef\aron@do@{\noexpand#1{req:\scantokens{#2\noexpand}}}%
    \aron@do@
  \endgroup
}

\catcode`\#=13
\def\makehashexcl{\def##{!}}
\def\makehashhash{\def##{\char35 }}
\makehashhash
\catcode`\#=6

\DeclareRobustCommand\HASH{\char35 }

\makeatother

这里我利用包\convertchar的宏stringstrings来改变全部出现到\#中?，并在标签中使用它。

\documentclass[a4paper]{scrartcl}
\usepackage[left=2cm,right=2cm,top=2.5cm,bottom=2cm]{geometry}
\usepackage{stringstrings}
\setlength\parindent{0pt}

\makeatletter
\newcommand{\req}[2]{%
  \convertchar[q]{#1}{\#}{?}%
  \begingroup%
    \textbf{#1}\def\@currentlabel{#1}\label{req:\thestring}~#2\newline
  \endgroup%
  \addcontentsline{lor}{requirement}{#1}%
} %

\DeclareNewTOC[%
  type=requirement, %
  types=requirements, %
  name=Anforderung, %
  listname={List of Requirements} %
]{lor}
\setuptoc{lor}{chapteratlist}

\begin{document}
\section{Test}
\req{MY.REQ.ID.42}{Lorem ipsum dolor sit amet,...}

\req{MY.REQ.ID.43\#BROKEN\#}{this requirement is broken,...}

Please have a look at \ref{req:MY.REQ.ID.42} on page~\pageref{req:MY.REQ.ID.42}

Please have a look at \ref{req:MY.REQ.ID.43?BROKEN?} on
