cgmd-parser
A full-featured markdown parser and compiler, written in JavaScript. With syntax improvements. Built for speed.
Yet another fork?
Yes. But with some little feature. It support text (and other content) aligment.
=> Right aligned text
>=< Center aligned
<=> Justify content
cgmd render it as div, but with one of this clasees: md-align-right
,md-align-center
or md-justify-content
. You must define styles for this blocks.
Install
npm install cgmd-parser --save
Usage
Minimal usage:
var md = require('cgmd-parser');
console.log(md('I am using __markdown__.'));
// Outputs: <p>I am using <strong>markdown</strong>.</p>
Example setting options with default values:
var marked = require('cgmd-parser');
marked.setOptions({
renderer: new marked.Renderer(),
gfm: true,
tables: true,
breaks: false,
pedantic: false,
sanitize: false,
smartLists: true,
smartypants: false
});
console.log(marked('I am using __markdown__.'));

marked(markdownString [,options] [,callback])
markdownString
Type: string
String of markdown source to be compiled.
options
Type: object
Hash of options. Can also be set using the marked.setOptions
method as seen
above.
callback
Type: function
Function called when the markdownString
has been fully parsed when using
async highlighting. If the options
argument is omitted, this can be used as
the second argument.
Options
highlight
Type: function
A function to highlight code blocks. The first example below uses async highlighting with node-pygmentize-bundled, and the second is a synchronous example using highlight.js:
var marked = require('cgmd-parser');
var markdownString = '```js\n console.log("hello"); \n```';
// Async highlighting with pygmentize-bundled
marked.setOptions({
highlight: function (code, lang, callback) {
require('pygmentize-bundled')({ lang: lang, format: 'html' }, code, function (err, result) {
callback(err, result.toString());
});
}
});
// Using async version of marked
marked(markdownString, function (err, content) {
if (err) throw err;
console.log(content);
});
// Synchronous highlighting with highlight.js
marked.setOptions({
highlight: function (code) {
return require('highlight.js').highlightAuto(code).value;
}
});
console.log(marked(markdownString));
highlight arguments
code
Type: string
The section of code to pass to the highlighter.
lang
Type: string
The programming language specified in the code block.
callback
Type: function
The callback function to call when using an async highlighter.
renderer
Type: object
Default: new Renderer()
An object containing functions to render tokens to HTML.
Overriding renderer methods
The renderer option allows you to render tokens in a custom manner. Here is an example of overriding the default heading token rendering by adding an embedded anchor tag like on GitHub:
var marked = require('cgmd-parser');
var renderer = new marked.Renderer();
renderer.heading = function (text, level) {
var escapedText = text.toLowerCase().replace(/[^\w]+/g, '-');
return '<h' + level + '><a name="' +
escapedText +
'" class="anchor" href="#' +
escapedText +
'"><span class="header-link"></span></a>' +
text + '</h' + level + '>';
},
console.log(marked('# heading+', { renderer: renderer }));
This code will output the following HTML:
<h1>
<a name="heading-" class="anchor" href="#heading-">
<span class="header-link"></span>
</a>
heading+
</h1>
Block level renderer methods
- code(string code, string language)
- blockquote(string quote)
- html(string html)
- heading(string text, number level)
- hr()
- list(string body, boolean ordered)
- listitem(string text)
- paragraph(string text)
- table(string header, string body)
- tablerow(string content)
- tablecell(string content, object flags)
flags
has the following properties:
{
header: true || false,
align: 'center' || 'left' || 'right'
}
Inline level renderer methods
- strong(string text)
- em(string text)
- codespan(string code)
- br()
- del(string text)
- link(string href, string title, string text)
- image(string href, string title, string text)
gfm
Type: boolean
Default: true
Enable GitHub flavored markdown.
tables
Type: boolean
Default: true
Enable GFM tables.
This option requires the gfm
option to be true.
breaks
Type: boolean
Default: false
Enable GFM line breaks.
This option requires the gfm
option to be true.
pedantic
Type: boolean
Default: false
Conform to obscure parts of markdown.pl
as much as possible. Don't fix any of
the original markdown bugs or poor behavior.
sanitize
Type: boolean
Default: false
Sanitize the output. Ignore any HTML that has been input.
smartLists
Type: boolean
Default: true
Use smarter list behavior than the original markdown. May eventually be
default with the old behavior moved into pedantic
.
smartypants
Type: boolean
Default: false
Use "smart" typograhic punctuation for things like quotes and dashes.
Access to lexer and parser
You also have direct access to the lexer and parser if you so desire.
var tokens = marked.lexer(text, options);
console.log(marked.parser(tokens));
var lexer = new marked.Lexer(options);
var tokens = lexer.lex(text);
console.log(tokens);
console.log(lexer.rules);
Benchmarks
node v0.8.x
$ node test --bench
marked completed in 3411ms.
marked (gfm) completed in 3727ms.
marked (pedantic) completed in 3201ms.
robotskirt completed in 808ms.
showdown (reuse converter) completed in 11954ms.
showdown (new converter) completed in 17774ms.
markdown-js completed in 17191ms.
Marked is now faster than Discount, which is written in C.
For those feeling skeptical: These benchmarks run the entire markdown test suite 1000 times. The test suite tests every feature. It doesn't cater to specific aspects.
