Extends MaRuKu markdown parsing to adding .to_html_snippet(lines).
A simpe way to generate document previews with out breaking links.

This might be useful for you main blog roll page to show a paragraph from your last 10 posts, each followed by a read more link

gem install maruku_snippet

This just addes the to_html_snippet(lines) method to maruku, everything else stays the same.

require 'maruku_snippet'

doc = MarukuSnippet.new(markdown_string)
puts doc.to_html_snippet(10)

Maruku would be:

require 'maruku'

doc = Maruku.new(markdown_string)
puts doc.to_html
