Build Status

A portable Markdown library written in Dart. It can parse Markdown into HTML on both the client and server.

Usage

import 'package:markdown/markdown.dart';

void main() {
  print(markdownToHtml('Hello *Markdown*'));
  //=> <p>Hello <em>Markdown</em></p>
}

Syntax extensions

A few Markdown extensions, beyond what was specified in the original Perl Markdown implementation, are supported. By default, the ones supported in CommonMark are enabled. Any individual extension can be enabled by specifying an Array of extension syntaxes in the blockSyntaxes or inlineSyntaxes argument of markdownToHtml.

The currently supported inline extension syntaxes are:

  • new InlineHtmlSyntax() - approximately CommonMark's definition of "Raw HTML".

The currently supported block extension syntaxes are:

  • const FencedCodeBlockSyntax() - Code blocks familiar to Pandoc and PHP Markdown Extra users.

  • const HeaderWithIdSyntax() - ATX-style headers have generated IDs, for link anchors (akin to Pandoc's auto_identifiers).

  • const SetextHeaderWithIdSyntax() - Setext-style headers have generated IDs for link anchors (akin to Pandoc's auto_identifiers).

For example:

import 'package:markdown/markdown.dart';

void main() {
  print(markdownToHtml('Hello <span class="green">Markdown</span>',
      inlineSyntaxes: [new InlineHtmlSyntax()]));
  //=> <p>Hello <span class="green">Markdown</span></p>
}

Extension Sets

To make extension management easy, you can also just specify an extension set. Both markdownToHtml() and new Document() accept an extensionSet named parameter. Right now there are two extension sets:

  • ExtensionSet.none includes no extensions. With no extensions, Markdown documents will be parsed closely to how they might be parsed by the original Perl Markdown implementation.

  • ExtensionSet.commonMark includes two extensions so far, which bring this package's Markdown parsing closer to what is found in the CommonMark spec:

  • new InlineHtmlSyntax()

  • const FencedCodeBlockSyntax()

Custom syntax extensions

You can create and use your own syntaxes.

import 'package:markdown/markdown.dart';

void main() {
  var syntaxes = [new TextSyntax('nyan', sub: '~=[,,_,,]:3')];
  print(markdownToHtml('nyan', inlineSyntaxes: syntaxes));
  //=> <p>~=[,,_,,]:3</p>
}
