Generate a markdown TOC (table of contents) with Remarkable.
(Table of contents generated by verb)
Features
Install with npm
$ npm i markdown-toc --save
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 renderingObject for creating a custom TOC.
toc('# AAA\n## BBB\n### CCC\nfoo').json;
// results in
[ { content: 'AAA', lvl: 1 },
{ content: 'BBB', lvl: 2 },
{ content: 'CCC', lvl: 3 } ]
Insert a table of contents immediately after an opening <!-- toc --> code comment, or replace an existing TOC if both an opening comment and a closing comment (<!-- tocstop -->) 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:
<!-- toc -->
- [abc](#abc)
- [xyz](#xyz)
<!-- tocstop -->
## abc
This is a b c.
## xyz
This is x y z.
As a convenience to folks who wants to create a custom TOC, markdown-toc's internal utility methods are exposed:
var toc = require('markdown-toc');
toc.bullets(): render a bullet list from an array of tokenstoc.linkify(): linking a heading content stringtoc.slugify(): slugify a heading content stringtoc.strip(): strip words or characters from a heading content stringExample
var result = toc('# AAA\n## BBB\n### CCC\nfoo');
var str = '';
result.json.forEach(function(heading) {
str += toc.linkify(heading.content);
});
Append a string to the end of the TOC.
toc(str, {append: '\n_(TOC generated by Verb)_'});
Type: Function
Default: undefined
Params:
str {String} the actual heading stringele {Objecct} object of heading tokensarr {Array} all of the headings objectsExample
From time to time, we might get junk like this in our TOC.
[.aaa([foo], ...) another bad heading](#-aaa--foo--------another-bad-heading)
Unless you like that kind of thing, you might want to filter these bad headings out.
function removeJunk(str, ele, arr) {
return str.indexOf('...') === -1;
}
var result = toc(str, {filter: removeJunk});
//=> beautiful TOC
Type: String|Array
Default: *
The bullet to use for each item in the generated TOC. If passed as an array (['*', '-', '+']), the bullet point strings will be used based on the header depth.
Type: Number
Default: 6
Use headings whose depth is at most maxdepth.
Type: Boolean
Default: true
Exclude the first h1-level heading in a file. For example, this prevents the first heading in a README from showing up in the TOC.

$ npm i -d && npm test
