建立目錄、lof 或批次等清單

Question 1

您可能可以使用 LaTeX2e-kernel-macros\@starttoc 和\addtocontents{<file-extension>}{<tokens>}.

\addtocontents將向 aux 檔案寫入（未展開）一些指令，以便在 LaTeX 運行結束時處理 aux 檔案時開啟該檔案以供輸入，以便未展開寫入<tokens>該檔案。\jobname.<file-extension>

\@starttoc{<file-extension>}如果該文件存在，將使 TeX 讀取/處理該文件\jobname.<file-extension>，然後銷毀該文件，然後重新建立它並開啟它以進行輸入，以便在 LaTeX 運行結束時處理輔助文件時，該文件已開啟用於輸入。

如果您想做一些更奇特的事情，請查看\addcontentslineLaTeX2e 核心的巨集。

基本上\addcontentsline{<file-extension>}{<command name>}{<tokens>}將向 aux 檔案寫入一些指令，以便在 LaTeX 運行結束時處理 aux 檔案時開啟檔案以供輸入，以便將標記序列未展開地寫入\contentsline{<command name>}{<tokens>}{<page number>}檔案中。在 LaTeX 運行結束時處理 aux 檔案期間 \jobname.<file-extension>寫入後，您將在其中找到該指令。因此，當檔案被讀取/處理時，該指令將被執行。\jobname.<file-extension>\contentsline{<command name>}{<tokens>}{<page number>}\@starttoc\jobname.<file-extension>

\contentsline{<command name>}{<tokens>}{<page number>}依序呼叫一個\l@<command name>處理兩個參數的宏，即<tokens>-argument 和<page number>-argument。

當此機制與 toc 檔案和分段命令一起使用時，<command name>將類似於section或subsection產生巨集的執行\l@section，或者\l@subsection但您也可以\l@..為自己的紅化類別定義自己的 - 巨集。

\addtocontents...-機制\@starttoc{<file-extension>}在其他事物之下定義了一個控制序列\tf@<file-extension>。因此，為了找出機制是否已經指派了\write用於寫入檔案的 -handle \jobname.<file-extension>，您可以使用\@ifundefined-macro 來檢查控制序列是否\tf@<file-extension>已定義。

但這僅在 scrwfile-package 未使用時有效 - 順便說一下：如果您打算在文檔中創建許多列表，如 toc、lof 或 lot，您可能會對 scrwfile-package 感興趣。有關該軟體包的更多資訊可以在 CTAN 上找到：https://www.ctan.org/pkg/scrwfile

LaTeX2e 核心在檔案 source2e.pdf 中進行了解釋和註釋，該檔案位於https://www.ctan.org/pkg/source2e。-
機制和使用該機制的巨集在名為檔案 F ltsect.dtx → 59 切片指令 → 59.3 目錄等的部分中進行了解釋。\addtocontents\@starttoc\addcontentsline

\documentclass{article}
\usepackage{hyperref}
\usepackage{verbatim}
\makeatletter
\newcommand\l@songline[2]{%
  \par Now we have data about another song:\\
  Title of song: #1. Song is printed on page: #2.%
}%
\makeatother
\begin{document}
\LaTeX{} will now write directives to aux-file for writing the first
 line into \jobname.weird. These directives will be carried out at
 the end of the \LaTeX-run when the aux-file is read/processed in
 case at that time the file \jobname.weird is open for writing to it.\\
\addtocontents{weird}{First line in file \jobname.weird.}%
\bigskip

This is what \jobname.weird looks like before calling \verb|\@starttoc|:    \\
\verbatiminput{\jobname.weird}
\bigskip

This is how \verb|\l@songline| is defined:\\{%
  \csname verbatim@font\endcsname\selectfont
  \expandafter\meaning\csname l@songline\endcsname
}%
\bigskip

The file \jobname.weird is \csname @ifundefined\endcsname{tf@weird}{not}{already} allocated.
\bigskip

\LaTeX will now read/process \jobname.weird and then destroy that file
and create it anew and open it for writing. Thus at the end of the
\LaTeX-run, when the aux-file is read/processed, that file will be open
for writing to it:\bigskip

\csname @starttoc\endcsname{weird}%
\bigskip

The file \jobname.weird is \csname @ifundefined\endcsname{tf@weird}{not}{already} allocated.
\bigskip

\LaTeX{} will now write directives to aux-file for writing the second
line into \jobname.weird. These directives will be carried out at
the end of the \LaTeX-run when the aux-file is read/processed in
case at that time the file \jobname.weird is open for writing to it.\\
\addtocontents{weird}{Second line in file \jobname.weird.}%
\bigskip

Now two \verb|\addcontentsline|-entries for writing things to \jobname.weird
that need to be "rubrified" by means of applying the \verb|l@songgline|-macro.
\addcontentsline{weird}{songline}{Morning has broken}
\addcontentsline{weird}{songline}{Final Countdown}

\end{document}
