Bookdown PDF输出中的目录之前的章节 [英] Chapter(s) before table of contents in Bookdown PDF output

问题描述

我想让一章出现在Bookdown的pdf_book输出中的目录之前(但标题页之后).

I'd like for a chapter to appear before the table of contents (but after the title page) in the pdf_book output of Bookdown.

执行此操作的一种方法是将章节添加到.tex文件并使用before_body:链接.但是，这意味着该章将不会出现在gitbook中(我也需要).我不想同时保留同一章的.tex和.Rmd版本.

One way to do this is to add the chapter to a .tex file and and link it using before_body:. However, this means the chapter will not appear in gitbook (which I also need). I'd prefer not to keep both a .tex and .Rmd version of the same chapter.

一个理想的解决方案是将该章保存在.Rmd文件中，并将其内容提取到before_body中作为pdf_book.这样，它仍可用于gitbook.尽管我不确定该怎么做，或者是否确实可行?

An ideal solution would be if the chapter could be kept in a .Rmd file, and its contents extracted into the before_body for pdf_book. That way it's still available for gitbook. Though I'm not sure how I might do that, or indeed if it's possible?

有解决方案吗?还是超出了Bookdown灵活性的限制?

Is there a solution? Or is it exceeding the limits of Bookdown's flexibility?

任何帮助将不胜感激，谢谢！

Any help would be greatly appreciated, thanks!

推荐答案

一个可以在文档中手动触发ToC创建，从而可以更好地控制其位置.当然，应该禁用自动创建目录表:

One can trigger ToC creation manually in the document, which gives more control over its placement. Of course, automatic table of contents creation should be disabled:

---
title: "MWE"
output:
  bookdown::pdf_book:
    toc: False
---

```{r child = 'file-you-want-to-include.Rmd'}
```

```{=latex}
% Trigger ToC creation in LaTeX
\tableofcontents
```

# Rest of your document starts here

缺点是，这仅适用于PDF输出，不适用于HTML.

The downside is that this only works with PDF output, not HTML.
