几个目录

Question

如果包含外部 tex 文件（通过 \input），该如何编辑代码？外部文件应该有自己独立的目录。

    \documentclass[a4paper]{article}
    % renew \contentsline for toc to include hypertarget
    \let\oldcontentsline\contentsline%
    \renewcommand\contentsline[4]{%
    \hypertarget{toc#4}{}%
    \oldcontentsline{#1}{#2}{#3}{#4}}

    % renew \section to link to the toc
    \titleformat{\section}
    {\normalfont\Large\bf}
    {{\thesection} \hyperlink{tocsection.\thesection}{#1}}
    {1pc}
    {}

    % renew \subsection to link to the toc
    \titleformat{\subsection}
    {\normalfont\bf}
    {{\thesection} \hyperlink{tocsubsection.                    \thesubsection}{#1}}
    {1pc}{}

    % renew \subsubsection to link to the toc
    \titleformat{\subsubsection}
    {\normalfont\bf}
    {{\thesection} \hyperlink{tocsubsubsection.        \thesubsubsection}{#1}}
    {1pc}{}

    \begin{document}
    \tableofcontents


    \section{abcd}


    \end{document}

感谢帮助！
