remark-toc

Generate a Table of Contents in remark.

Installation

npm:

npm install remark-toc

Usage

Say we have the following file, example.md:

# Alpha

## Table of Contents

## Bravo

### Charlie

## Delta

And our script, example.js, looks as follows:

var vfile = require('to-vfile');
var remark = require('remark');
var toc = require('remark-toc');

remark()
  .use(toc)
  .process(vfile.readSync('example.md'), function (err, file) {
    if (err) throw err;
    console.log(String(file));
  });

Now, running node example yields:

# Alpha

## Table of Contents

-   [Bravo](#bravo)

    -   [Charlie](#charlie)

-   [Delta](#delta)

## Bravo

### Charlie

## Delta

API

remark().use(toc[, options])

Add a Table of Contents to a Markdown document.

• Looks for the first heading containing "Table of Contents", "toc", or table-of-contents (case insensitive, supports alt/title attributes for links and images too)
• Removes all following contents until an equal or higher heading is found
• Inserts a list representation of the hierarchy of following headings
• Adds links to following headings, using the same slugs as GitHub

Options

heading

string?, default: "toc|table[ -]of[ -]contents?" — Heading to look for, wrapped in new RegExp('^(' + value + ')$', 'i').

maxDepth

number?, default: 6 — Maximum heading depth to include in the table of contents, This is inclusive, thus, when set to 3, level three headings, are included (those with three hashes, ###).

tight

boolean?, default: false — Whether to compile list-items tightly.
