Class Method Details

.engine ⇒ Object

# RDiscount: rubygems.org/gems/rdiscount # Maruku: rubygems.org/gems/maruku # PEGMarkdown: rubygems.org/gems/rpeg-markdown # BlueCloth: rubygems.org/gems/bluecloth # Redcarpet: rubygems.org/gems/redcarpet # Kramdown: kramdown.rubyforge.org/

Note: RDiscount will always be installed as Kitabu’s dependency but only used when no alternative library is available.
