如果你正在使用Discount markdown，启用一个标志-ftoc来自动生成，并使用-T来在一个目录的前面，例如:

markdown -T -ftoc <<EOT
#heading 1

content 1

##heading 2

content 2
EOT

将会产生

<ul>
 <li><a href="#heading-1">heading 1</a>
 <ul>
  <li><a href="#heading-2">heading 2</a></li>
 </ul>
 </li>
</ul>
<a name="heading-1"></a>
<h1>heading 1</h1>
...

显然你也可以使用markdown -toc，这个人没有提到，但是USAGE信息可以(由markdown -h这样的非法选项触发)。

我花了一段时间阅读源代码才明白这一点，所以我把它写下来主要是为了未来的我。我在Arch Linux上使用折扣降价，从折扣包。这个人并没有真正告诉你这是折扣，但提到了大卫·帕森斯的作者。

markdown --version
# markdown: discount 2.2.7

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

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);

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。

您可以尝试使用这个ruby脚本从标记文件生成TOC。

 #!/usr/bin/env ruby

require 'uri'

fileName = ARGV[0]
fileName = "README.md" if !fileName

File.open(fileName, 'r') do |f|
  inside_code_snippet = false
  f.each_line do |line|
    forbidden_words = ['Table of contents', 'define', 'pragma']
    inside_code_snippet = !inside_code_snippet if line.start_with?('```')
    next if !line.start_with?("#") || forbidden_words.any? { |w| line =~ /#{w}/ } || inside_code_snippet

    title = line.gsub("#", "").strip
    href = URI::encode title.gsub(" ", "-").downcase
    puts "  " * (line.count("#")-1) + "* [#{title}](\##{href})"
  end
end

如果IntelliJ用户do:，命令n或控件n提供创建或更新目录的选项。参考资料:阅读此处
