这是一个简短的PHP代码，我用来生成TOC，并丰富任何标题与锚:

$toc = []; //initialize the toc to an empty array
$markdown = "... your mardown content here...";

$markdown = preg_replace_callback("/(#+)\s*([^\n]+)/",function($matches) use (&$toc){
    static $section = [];
    $h = strlen($matches[1]);

    @$section[$h-1]++;
    $i = $h;
    while(isset($section[$i])) unset($section[$i++]);

    $anchor = preg_replace('/\s+/','-', strtolower(trim($matches[2])));

    $toc[] = str_repeat('  ',$h-1)."* [".implode('.',$section).". {$matches[2]}](#$anchor)";
    return str_repeat('#',$h)." <strong>".implode('.',$section).".</strong> ".$matches[2]."\n<a name=\"$anchor\"></a>\n";
}, $markdown);

然后你可以打印经过处理的markdown和toc:

   print(implode("\n",$toc));
   print("\n\n");
   print($markdown);

基于albertodebortoli answer创建了附加检查和标点符号替换功能。

# @fn       def generate_table_of_contents markdown # {{{
# @brief    Generates table of contents for given markdown text
#
# @param    [String]  markdown Markdown string e.g. File.read('README.md')
#
# @return   [String]  Table of content in markdown format.
#
def generate_table_of_contents markdown
  table_of_contents = ""
  i_section = 0
  # to track markdown code sections, because e.g. ruby comments also start with #
  inside_code_section = false
  markdown.each_line do |line|
    inside_code_section = !inside_code_section if line.start_with?('```')

    forbidden_words = ['Table of contents', 'define', 'pragma']
    next if !line.start_with?('#') || inside_code_section || forbidden_words.any? { |w| line =~ /#{w}/ }

    title = line.gsub("#", "").strip
    href = title.gsub(/(^[!.?:\(\)]+|[!.?:\(\)]+$)/, '').gsub(/[!.,?:; \(\)-]+/, "-").downcase

    bullet = line.count("#") > 1 ? " *" : "#{i_section += 1}."
    table_of_contents << "  " * (line.count("#") - 1) + "#{bullet} [#{title}](\##{href})\n"
  end
  table_of_contents
end

正如在其他回答中提到的，有多种方法可以自动生成目录。大多数都是开源软件，可以根据您的需要进行调整。

然而，我所缺少的是，使用Markdown提供的有限选项，在视觉上吸引人的目录格式。我们得出了以下结论:

Code

## Content

**[1. Markdown](#heading--1)**

  * [1.1. Markdown formatting cheatsheet](#heading--1-1)
  * [1.2. Markdown formatting details](#heading--1-2)

**[2. BBCode formatting](#heading--2)**

  * [2.1. Basic text formatting](#heading--2-1)

      * [2.1.1. Not so basic text formatting](#heading--2-1-1)

  * [2.2. Lists, Images, Code](#heading--2-2)
  * [2.3. Special features](#heading--2-3)

----

在你的文档中，你可以像这样放置目标子部分标记:

<div id="heading--1-1"/>
### 1.1. Markdown formatting cheatsheet

根据你在哪里以及如何使用Markdown，以下也应该工作，并提供了更好看Markdown代码:

### 1.1. Markdown formatting cheatsheet <a name="heading--1-1"/>

例子呈现

内容 1. 减价 1.1. 折算格式备忘单 1.2. 折扣价格式细节 2. BBCode格式化 2.1. 基本文本格式 2.1.1. 不是最基本的文本格式 2.2. 列表，图像，代码 2.3. 特殊功能

优势

You can add as many levels of chapters and sub-chapters as you need. In the Table of Contents, these would appear as nested unordered lists on deeper levels. No use of ordered lists. These would create an indentation, would not link the number, and cannot be used to create decimal classification numbering like "1.1.". No use of lists for the first level. Here, using an unordered list is possible, but not necessary: the indentation and bullet just add visual clutter and no function here, so we don't use a list for the first ToC level at all. Visual emphasis on the first-level sections in the table of content by bold print. Short, meaningful subpart markers that look "beautiful" in the browser's URL bar such as #heading--1-1 rather than markers containing transformed pieces of the actual heading. The code uses H2 headings (## …) for sections, H3 headings (### …) for sub-headings etc.. This makes the source code easier to read because ## … provides a stronger visual clue when scrolling through compared to the case where sections would start with H1 headings (# …). It is still logically consistent as you use the H1 heading for the document title itself. Finally, we add a nice horizontal rule to separate the table of contents from the actual content.

有关这项技术以及我们如何在论坛软件Discourse中使用它的更多信息，请参见这里。

你可以使用DocToc从命令行生成目录:

doctoc /path/to/file

要使链接与Bitbucket生成的锚点兼容，请使用——Bitbucket参数运行它。

在Visual Studio Code (VSCode)中，您可以使用扩展Markdown All In One。

安装完成后，请按照以下步骤操作:

按CTRL + SHIFT + P 选择Markdown:创建目录

编辑:现在我使用DocToc来生成目录，详见我的其他答案。

只需使用带有插件的文本编辑器。

你的编辑器很可能有一个包/插件来为你处理这个问题。例如，在Emacs中，可以安装markdown-toc TOC生成器。然后在编辑时，只需反复调用M-x markdown-toc-generate-or-refresh-toc。如果你想经常这样做，那就值得一个键绑定。它擅长生成一个简单的TOC，而不会用HTML锚污染您的文档。

其他编辑器也有类似的插件，所以流行的列表是这样的:

器name: markdown-toc Vim: markdown-toc Atom: markdown-toc VSCode: markdown-toc
