为 \include(only) 设置子文件夹

为 \include(only) 设置子文件夹

我们假设一个项目有一个主文件，main.tex其中包括带有 的章节\include。

% main.tex
\documentclass{book}

\includeonly{one}

\begin{document}
\include{one}
\include{two}
\end{document}


% one.tex
\chapter{First chapter}
Some text


% two.tex
\chapter{Second chapter}
Some text

为了保持目录整洁，章节应保存在名为的文件夹中chapters/。这样做也意味着将文件夹添加到每个\include宏中，以及添加到\includeonly。

\documentclass{book}

\includeonly{chapters/one}

\begin{document}
\include{chapters/one}
\include{chapters/two}
\end{document}

所以我想知道是否可以更改使用的默认路径\include(only)？

似乎可以破解 的定义\include(only)。这似乎可行，但我不确定后果如何……

\documentclass{book}

\makeatletter
\def\include#1{\relax
   \ifnum\@auxout=\@partaux
     \@latex@error{\string\include\space cannot be nested}\@eha
   \else \@include{chapters/#1} \fi%
}
\def\includeonly#1{%
   \@partswtrue
   \edef\@partlist{\zap@space chapters/#1 \@empty}%
}
\makeatother

\includeonly{one}

\begin{document}
\include{one}
\include{two}
\end{document}

我考虑将其做成一个小包，提供一个宏\includepath{<dir>}来自动添加目录。这样做会不会没有任何危害？

\documentclass{book}

\makeatletter
\def\@includepath{}
\newcommand*{\includepath}[1]{%
   \xdef\@includepath{#1}%
}
\@onlypreamble\includepath
\def\include#1{\relax
   \ifnum\@auxout=\@partaux
     \@latex@error{\string\include\space cannot be nested}\@eha
   \else \expandafter\@include{\@includepath#1} \fi%
}
\def\includeonly#1{%
   \@partswtrue
   \edef\@partlist{\expandafter\zap@space\@includepath#1 \@empty}%
   \renewcommand*{\includepath}[1]{%
      \typeout{ERROR: \string\includepath\space must be
      used before \string\includeonly!}
   }
}
\makeatother


\includeonly{two}

\begin{document}
\include{one}
\include{two}
\end{document}
