marked
A full-featured markdown parser and compiler, written in javascript. Built for speed.
Install
Usage
Minimal usage:
Example using all options:
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 as seen above:
Options
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.
renderer
Type: Renderer
Default: new Renderer()
A renderer instance for rendering ast to html. Learn more on the Renderer section.
Renderer
Renderer is a the new way for rendering tokens to html. Here is a simple example:
You can control anything you want.
Block Level
code(code, language)
blockquote(quote)
html(html)
heading(text, level)
hr()
list(body, ordered)
listitem(text)
paragraph(text)
table(header, body)
tablerow(content)
tablecell(content, flags)
flags
is an object like this:
Span Level
strong(text)
em(text)
codespan(code)
br()
del(text)
link(href, title, text)
image(href, title, text)
Access to lexer and parser
You also have direct access to the lexer and parser if you so desire.
CLI
Benchmarks
node v0.4.x
node v0.6.x
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.
node v0.8.x
Another Javascript Markdown Parser
The point of marked was to create a markdown compiler where it was possible to frequently parse huge chunks of markdown without having to worry about caching the compiled output somehow...or blocking for an unnecesarily long time.
marked is very concise and still implements all markdown features. It is also now fully compatible with the client-side.
marked more or less passes the official markdown test suite in its entirety. This is important because a surprising number of markdown compilers cannot pass more than a few tests. It was very difficult to get marked as compliant as it is. It could have cut corners in several areas for the sake of performance, but did not in order to be exactly what you expect in terms of a markdown rendering. In fact, this is why marked could be considered at a disadvantage in the benchmarks above.
Along with implementing every markdown feature, marked also implements GFM features.
High level
You can customize the result with a customized renderer.
The renderer API:
Pro level
You also have direct access to the lexer and parser if you so desire.
Running Tests & Contributing
If you want to submit a pull request, make sure your changes pass the test suite. If you're adding a new feature, be sure to add your own test.
The marked test suite is set up slightly strangely: test/new
is for all tests that are not part of the original markdown.pl test suite (this is where your test should go if you make one). test/original
is only for the original markdown.pl tests. test/tests
houses both types of tests after they have been combined and moved/generated by running node test --fix
or marked --test --fix
.
In other words, if you have a test to add, add it to test/new/
and then regenerate the tests with node test --fix
. Commit the result. If your test uses a certain feature, for example, maybe it assumes GFM is not enabled, you can add .nogfm
to the filename. So, my-test.text
becomes my-test.nogfm.text
. You can do this with any marked option. Say you want line breaks and smartypants enabled, your filename should be: my-test.breaks.smartypants.text
.
To run the tests:
