The following markups are supported. The dependencies listed are required if you wish to run the library.

[.markdown](http://daringfireball.net/projects/markdown/) -- `gem install redcarpet`
[.textile](http://www.textism.com/tools/textile/) -- `gem install RedCloth`
[.rdoc](http://rdoc.sourceforge.net/) -- `gem install rdoc -v 3.6.1`
[.org](http://orgmode.org/) -- `gem install org-ruby`
[.creole](http://wikicreole.org/) -- `gem install creole`
[.mediawiki](http://www.mediawiki.org/wiki/Help:Formatting) -- `gem install wikicloth`
[.rst](http://docutils.sourceforge.net/rst.html) -- `easy_install docutils`
[.asciidoc](http://www.methods.co.nz/asciidoc/) -- `brew install asciidoc`
[.pod](http://search.cpan.org/dist/perl/pod/perlpod.pod) -- `Pod::Simple::HTML`

  comes with Perl >= 5.10. Lower versions should install Pod::Simple from CPAN.

.1 - Requires [`groff`](http://www.gnu.org/software/groff/)

Contributing

Want to contribute? Great! There are two ways to add markups.

1. 1. Commands

If your markup is in a language other than Ruby, drop a translator script in `lib/github/commands` which accepts input on STDIN and returns HTML on STDOUT. See [rest2html][r2h] for an example.

Once your script is in place, edit `lib/github/markups.rb` and tell GitHub Markup about it. Again we look to [rest2html][r2hc] for guidance:

    command(:rest2html, /re?st(.txt)?/)

Here we're telling GitHub Markup of the existence of a `rest2html` command which should be used for any file ending in `rest`, `rst`, `rest.txt` or `rst.txt`. Any regular expression will do.

Finally add your tests. Create a `README.extension` in `test/markups` along with a `README.extension.html`. As you may imagine, the `README.extension` should be your known input and the `README.extension.html` should be the desired output.

Now run the tests: `rake`

If nothing complains, congratulations!

1. 1. Classes

If your markup can be translated using a Ruby library, that's great. Check out Check `lib/github/markups.rb` for some examples. Let's look at Markdown:

    markup(:markdown, /md|mkdn?|markdown/) do |content|
      Markdown.new(content).to_html
    end

We give the `markup` method three bits of information: the name of the file to `require`, a regular expression for extensions to match, and a block to run with unformatted markup which should return HTML.

If you need to monkeypatch a RubyGem or something, check out the included RDoc example.

Tests should be added in the same manner as described under the `Commands` section.

Installation

    gem install github-markup

Usage

    require 'github/markup'
    GitHub::Markup.render('README.markdown', "* One\n* Two")

Or, more realistically:

    require 'github/markup'
    GitHub::Markup.render(file, File.read(file))

Testing

To run the tests:

    $ rake

To add tests see the `Commands` section earlier in this README.
