CLI

Usage: markdown-toc [options] <input>

  input:        The Markdown file to parse for table of contents,
                or "-" to read from stdin.

  -i:           Edit the <input> file directly, injecting the TOC at <!-- toc -->;
                (Without this flag, the default is to print the TOC to stdout.)

  --json:       Print the TOC in JSON format

  --append:     Append a string to the end of the TOC

  --bullets:    Bullets to use for items in the generated TOC
                (Supports multiple bullets: --bullets "*" --bullets "-" --bullets "+")
                (Default is "*".)

  --maxdepth:   Use headings whose depth is at most maxdepth
                (Default is 6.)

  --no-firsth1: Include the first h1-level heading in a file

  --no-stripHeadingTags: Do not strip extraneous HTML tags from heading
                         text before slugifying

Highlights

Features

Can optionally be used as a remarkable plugin
Returns an object with the rendered TOC (on content), as well as a json property with the raw TOC object, so you can generate your own TOC using templates or however you want
Works with repeated headings
Uses sane defaults, so no customization is necessary, but you can if you need to.
filter out headings you don't want
Improve the headings you do want
Use a custom slugify function to change how links are created

Safe!

Won't mangle markdown in code examples in gfm code blocks that other TOC generators mistake as being actual headings (this happens when markdown headings are show in examples, meaning they arent' actually headings that should be in the toc. Also happens with yaml and coffee-script comments, or any comments that use #)
Won't mangle front-matter, or mistake front-matter properties for headings like other TOC generators

Usage

var toc = require('markdown-toc');

toc('# One\n\n# Two').content;
// Results in:
// - [One](#one)
// - [Two](#two)

To allow customization of the output, an object is returned with the following properties:

content {String}: The generated table of contents. Unless you want to customize rendering, this is all you need.
highest {Number}: The highest level heading found. This is used to adjust indentation.
tokens {Array}: Headings tokens that can be used for custom rendering

API

toc.plugin

Use as a remarkable plugin.

var Remarkable = require('remarkable');
var toc = require('markdown-toc');

function render(str, options) {
  return new Remarkable()
    .use(toc.plugin(options)) // <= register the plugin
    .render(str);
}

Usage example

var results = render('# AAA\n# BBB\n# CCC\nfoo\nbar\nbaz');

Results in:

- [AAA](#aaa)
- [BBB](#bbb)
- [CCC](#ccc)

toc.json

Object for creating a custom TOC.

toc('# AAA\n## BBB\n### CCC\nfoo').json;

// results in
[ { content: 'AAA', slug: 'aaa', lvl: 1 },
  { content: 'BBB', slug: 'bbb', lvl: 2 },
  { content: 'CCC', slug: 'ccc', lvl: 3 } ]

toc.insert

Insert a table of contents immediately after an opening  code comment, or replace an existing TOC if both an opening comment and a closing comment () are found.

(This strategy works well since code comments in markdown are hidden when viewed as HTML, like when viewing a README on GitHub README for example).

Example

<!-- toc -->
- old toc 1
- old toc 2
- old toc 3
<!-- tocstop -->

## abc
This is a b c.

## xyz
This is x y z.

Would result in something like:
