# Discount is an implementation of John Gruber's Markdown markup
# language in C. It implements all of the language as described in
# {Markdown Syntax}[http://daringfireball.net/projects/markdown/syntax]
# and passes the Markdown 1.0 test suite. The RDiscount extension makes
# the Discount processor available via a Ruby C Extension library.
#
# == Usage
#
# RDiscount implements the basic protocol popularized by RedCloth and adopted
# by BlueCloth:
# require 'rdiscount'
# markdown = RDiscount.new("Hello World!")
# puts markdown.to_html
#
# == Replacing BlueCloth
#
# Inject RDiscount into your BlueCloth-using code by replacing your bluecloth
# require statements with the following:
# begin
# require 'rdiscount'
# BlueCloth = RDiscount
# rescue LoadError
# require 'bluecloth'
# end
#
class RDiscount
VERSION = '1.6.3'
# Original Markdown formatted text.
attr_reader :text
# Set true to have smarty-like quote translation performed.
attr_accessor :smart
# Do not output <style> tags included in the source text.
attr_accessor :filter_styles
# Do not output any raw HTML included in the source text.
attr_accessor :filter_html
# RedCloth compatible line folding -- not used for Markdown but
# included for compatibility.
attr_accessor :fold_lines
# Enable Table Of Contents generation
attr_accessor :generate_toc
# Create a RDiscount Markdown processor. The +text+ argument
# should be a string containing Markdown text. Additional arguments may be
# supplied to set various processing options:
#
# * <tt>:smart</tt> - Enable SmartyPants processing.
# * <tt>:filter_styles</tt> - Do not output <tt><style></tt> tags.
# * <tt>:filter_html</tt> - Do not output any raw HTML tags included in
# the source text.
# * <tt>:fold_lines</tt> - RedCloth compatible line folding (not used).
#
# NOTE: The <tt>:filter_styles</tt> extension is not yet implemented.
