Module: CodeRay::ForRedCloth
- Defined in:
- lib/rubypitaya/app-template/vendor/bundle/ruby/3.1.0/gems/coderay-1.1.3/lib/coderay/for_redcloth.rb
Overview
A little hack to enable CodeRay highlighting in RedCloth.
Usage:
require 'coderay'
require 'coderay/for_redcloth'
RedCloth.new('@[ruby]puts "Hello, World!"@').to_html
Make sure you have RedCloth 4.0.3 activated, for example by calling
require 'rubygems'
before RedCloth is loaded and before calling CodeRay.for_redcloth.
