测试文件是否在 \includeonly 中

测试文件是否在 \includeonly 中

是否可以检查文件是否列在里面\includeonly{...}？

例如我想做这样的事情

\includeonly{file1,file2}
\if\isincluded file1       % \isincluded is a placeholder for the real test macro 
   \usepackage{apackage}
 \fi

 \begin{document}
 \include{file1}
 \include{file2}
 \end{document}

避免apackage在未包含 file1 时加载（因为该包的加载成本很高，例如 TikZ）

答案1

以下宏\isincluded使用与使用相同的测试\include（从那里复制的代码）。如果将包含第一个参数中的文件，则调用第二个参数，否则调用第三个参数。此外，宏会捕获未\includeonly使用的情况，并包含所有文件。

\documentclass{article}
\includeonly{file,file2}                     

\makeatletter
\newcommand*{\isincluded}[1]{%
  \@tempswatrue
  \if@partsw   
    \@tempswafalse
    \edef\reserved@b{#1}%
    \@for\reserved@a:=\@partlist\do
      {\ifx\reserved@a\reserved@b\@tempswatrue\fi}%
  \fi
  \if@tempswa
    \expandafter\@firstoftwo
  \else
    \expandafter\@secondoftwo
  \fi
}
\makeatother

\isincluded{file1}{%
  \usepackage{apackage}%
}{}

\begin{document}
\include{file1} 
\include{file2} 
\end{document}

如果\includeonly使用 ，则开关\if@partsw为真。然后 的文件\includeonly可在 中使用\@partlist。

扩展：\isincluded带有文件列表

用例：如果包含某些文件，则必须加载资源（包）。这意味着如果\isincluded包含 中的任一文件，则 的测试 \isincluded结果为 true（逗号为“或”运算符）：

\documentclass{article}
\includeonly{file1,file3}

\makeatletter
\newcommand*{\isincluded}[1]{%
  \@tempswatrue
  \if@partsw
    \@tempswafalse
    \edef\isincluded@list{\zap@space#1 \@empty}% removes spaces in file list
    \@for\reserved@b:=\isincluded@list\do{%
      \@for\reserved@a:=\@partlist\do{%
        \ifx\reserved@a\reserved@b\@tempswatrue\fi
      }%
    }%  
  \fi   
  \if@tempswa
    \expandafter\@firstoftwo
  \else
    \expandafter\@secondoftwo
  \fi
}
\makeatother

\isincluded{file2,file3}{%
  \usepackage{apackage}%
}{}

\begin{document}
\include{file1} 
\include{file2} 
\include{file3}
\end{document}

答案2

文件\includeonly已保存并edef称为\@partlist。

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{test1.tex}
  file 1
\end{filecontents}
\begin{filecontents}{test2.tex}
  file 2
\end{filecontents}
\includeonly{test2, test1}
\begin{document}
\makeatletter
 \@partlist
\makeatother
\meaning\@partlist
\end{document}

不太确定这是否有帮助，但你可以阅读 source2e 例程。

答案3

您可以编写自己的包装器来\includeonly测试文件名

\documentclass{article}
\usepackage{etoolbox}

\newcommand{\myincludeonly}[1]{%
  \def\do##1{\ifstrequal{##1}{file1}{\usepackage{tikz}}{}}
  \docsvlist{#1}
  \includeonly{#1}
}
\myincludeonly{file1,file2}

\begin{document}
\include{file1}
\include{file2}
\end{document}

答案4

以下是我对 Heiko 解决方案提出的问题。在下文中，韓國尽管\includeonly被注释掉了，但仍是输入。

\documentclass{article}
%\includeonly{file,file2} % commented

\makeatletter
\newcommand*{\isincluded}[1]{%
  \@tempswatrue
  \if@partsw
    \@tempswafalse
    \edef\isincluded@list{\zap@space#1 \@empty}%
    \@for\reserved@b:=\isincluded@list\do{%
      \@for\reserved@a:=\@partlist\do{%
        \ifx\reserved@a\reserved@b\@tempswatrue\fi
      }%
    }%
  \fi
  \if@tempswa
    \expandafter\@firstoftwo
  \else
    \expandafter\@secondoftwo
  \fi
}
\makeatother

\isincluded{file1}{%
  \usepackage{ifpdf}%
}{}

\begin{document}
\include{file1}
\include{file2}
\end{document}

我的方法是

\documentclass{article}
% Comment out or retain the following:
\includeonly{file,file2}                     

\makeatletter
\newif\if@tempswb
\newcommand*{\ifincluded}[1]{%
  \begingroup
  \@tempswbfalse
  \if@partsw
    \edef\@tempa{\zap@space#1 \@empty}%
    \@for\reserved@b:=\@tempa\do{%
      \@for\reserved@a:=\@partlist\do{%
        \ifx\reserved@a\reserved@b\@tempswbtrue\fi
      }%
    }%  
  \fi   
  \expandafter\endgroup
  \if@tempswb
    \expandafter\@firstoftwo
  \else
    \expandafter\@secondoftwo
  \fi
}
\makeatother

\ifincluded{file1}{%
  \usepackage{ifpdf}%
}{}

\begin{document}
\include{file1} 
\include{file2} 
\end{document}
