Docter

❗ NO LONGER MAINTAINED ❗

Check out chjj/marked if you're looking for a good javascript markdown parser. Sorry!

Uses github's own redcarpet library to provide accurate markdown previews in your local editor. This screenshot shows Marked using docter as the markdown processor.

Why NodeJS and not ruby?

I have future plans for this in a node project. And because it's my party.

Requirements

Lots. Ungodly heaps of requirements.

• NodeJS and NPM if you plan on using the node wrapper.

• Ruby & Rubygems

• Various gems

   $ gem install redcarpet pygments.rb

Usage

1. Clone this repo locally
2. cd to the repo
3. [sudo] npm -g install

This will install the package into your global node_modules dir (usually /usr/local/lib/node_modules). It will also symbolically link two executables into your path:

1. docter: the nodejs wrapper.
2. gfm: the ruby redcarpet/pygments wrapper.

Both of these executables take markdown input through STDIN and output formatted HTML on STDOUT.

Using with Marked.app

1. Set the markdown processor to either of the linked executables. If you don't plan on doing anything with the node wrapper, I would suggest using the straight ruby wrapper (gfm).
2. Optionally, add the ghf_marked.css (in this repo) to Marked's custom CSS list.

Other styles

Uncomment the doc_header() function in github-flavored-markdown.rb and include any of the built-in styles from pygments. Replace :style => 'vs' with one of the styles in the comment block.

Outputting the emacs style to the document header:

class HTMLwithPygments < Redcarpet::Render::XHTML
	def doc_header()
		'<style>' + Pygments.css('.highlight',:style => 'emacs') + '</style>'
	end
	def block_code(code, language)
		Pygments.highlight(code, :lexer => language, :options => {:encoding => 'utf-8'})
	end
end
