根据包含 \source{} 的图形标题生成图形来源列表

这个问题源自于从 \includegraphics 生成图形编号和文件名列表。那里的答案提供了从 LaTeX 源生成图号和相关文件名的文本文件的基本代码。现在，我需要将此方法扩展到进一步的任务，即收集图源的文本文件。

在这本书中（几乎）全部图\caption{}中包含了source{}给出图形源的命令。它目前仅被定义为以文本形式打印有关图形源的信息，来源：斜体

\newcommand{\source}[1]{\emph{Source:} #1.}

有些图表需要许可，有些则不需要，但为了出版，出版商需要所有图表及其来源和许可状态的列表。

我希望至少从 LaTeX 源中提取此基础，通过修改\source{}命令来将行写入来源列表（los） 文件。

需要获得许可的图形的一个例子是：

\begin{figure}[htb]
  \centering
  \includegraphics[width=.6\textwidth]{\theChapter/fig/cholera-monmonier-gilbert}
  \caption[\desc{Presentation graphic} Mark Monmonier's re-vision of the Gilbert version of Snow's map, as
  a presentation graphic]{\desc{Presentation graphic} Mark Monmonier's re-vision of the Gilbert version of Snow's map, as
a presentation graphic. \source{Monmonier (1996), \emph{How to Lie with
Maps}, p. 158. Image: permission required, University of Chicago Press.}
}

如果这是书中的图 4.10，我希望重新定义的\source{}命令将一行写入文件，los例如：

4.10 Monmonier (1996), \emph{How to Lie with Maps}, p. 158. Image: permission required, University of Chicago Press.

换句话说： 通缉：一种修改方法\source{}，以便它也能将行写入外部文件\jobname.los，格式如下

fignum source

有人可以帮忙吗？

我从链接的答案中获取（这是我的答案）并添加了命令\source，写入.los并\addcontentsline添加，\thefigure以便清楚哪个图形和哪个来源属于一起。

\addcontentsline{los}{section}{\thefigure: #1}

将相关内容添加到.los文件中，格式与section常规的 类似ToC。\@starttoc{los}读取.los文件并显示其内容。代码与 非常相似\tableofcontents。

\usepackage{graphicx}
