Our chimpy flavour of Redcarpet Markdown with a few escaping tricks for merge tags and content writer friendly extensions.

In your Gemfile:

gem "mc_markdown", git: 'git@github.com:mailchimp/mc_markdown.git'

Then bundle install

Rendering with the Base renderer

MCMarkdown.render "# Hello World"
# => '<h1>Hello World</h1>'

MCMarkdown.render "*|MERGE_TASTIC|*"
# => '<p>*|MERGE_TASTIC|*</p>'

MCMarkdown.render "[Sign Up {btn}](/signup)"
# => '<a href="/signup" class="btn">Sign Up</a>'

Getting a renderer to use

html = MCMarkdown::Renderers.use :html
# => MCMarkdown::HTML initialized for Redcarpet::Markdown

html.render '# Hello World'
# => '<h1>Hello World</h1>'

Can also extract frontmatter

frontmatter, html = MCMarkdown.render_with_frontmatter "---\nfoo:bar\n---\n\n# Hello World"
# => { "foo" => "bar" }, "<h1>Hello World\n"

Renderers
Our "top level" objects, they coordinate collections of formatters and take the #render method to render our input markdown.

Formatters
Formatters are the individual parts that differ from the base Redcarpet implementation. Some implement something like "shortag" codes in markdown.

$ rspec
# => runs the test suite
