#
# Based on (and also inspired by) both:

#
# = RedCloth
#
# RedCloth is a Ruby library for converting Textile and/or Markdown
# into HTML. You can use either format, intermingled or separately.
# You can also extend RedCloth to honor your own custom text stylings.
#
# RedCloth users are encouraged to use Textile if they are generating
# HTML and to use Markdown if others will be viewing the plain text.
#
# == What is Textile?
#
# Textile is a simple formatting style for text
# documents, loosely based on some HTML conventions.
#
# == Sample Textile Text
#
# h2. This is a title
#
# h3. This is a subhead
#
# This is a bit of paragraph.
#
# bq. This is a blockquote.
#
# = Writing Textile
#
# A Textile document consists of paragraphs. Paragraphs
# can be specially formatted by adding a small instruction
# to the beginning of the paragraph.
#
# h[n]. Header of size [n].
# bq. Blockquote.
# # Numeric list.
# * Bulleted list.
#
# == Quick Phrase Modifiers
#
# Quick phrase modifiers are also included, to allow formatting
# of small portions of text within a paragraph.
#
# \_emphasis\_
# \_\_italicized\_\_
# \*strong\*
# \*\*bold\*\*
# ??citation??
# -deleted text-
# +inserted text+
# ^superscript^
# ~subscript~
# @code@
# %(classname)span%
#
# ==notextile== (leave text alone)
#
# == Links
#
# To make a hypertext link, put the link text in "quotation
# marks" followed immediately by a colon and the URL of the link.
#
# Optional: text in (parentheses) following the link text,
# but before the closing quotation mark, will become a Title
# attribute for the link, visible as a tool tip when a cursor is above it.
#
# Example:
#
# "This is a link (This is a title) ":http://www.textism.com
#
# Will become:
#
# <a href="http://www.textism.com" title="This is a title">This is a link</a>
#
# == Images
#
# To insert an image, put the URL for the image inside exclamation marks.
#
# Optional: text that immediately follows the URL in (parentheses) will
# be used as the Alt text for the image. Images on the web should always
# have descriptive Alt text for the benefit of readers using non-graphical
# browsers.
#
# Optional: place a colon followed by a URL immediately after the
# closing ! to make the image into a link.
#
# Example:
#
# !http://www.textism.com/common/textist.gif(Textist)!
#
# Will become:
#
# <img src="http://www.textism.com/common/textist.gif" alt="Textist" />
#
# With a link:
#
# !/common/textist.gif(Textist)!:http://textism.com
#
# Will become:
#
# <a href="http://textism.com"><img src="/common/textist.gif" alt="Textist" /></a>
#
# == Defining Acronyms
#
# HTML allows authors to define acronyms via the tag. The definition appears as a
# tool tip when a cursor hovers over the acronym. A crucial aid to clear writing,
# this should be used at least once for each acronym in documents where they appear.
#
# To quickly define an acronym in Textile, place the full text in (parentheses)
# immediately following the acronym.
#
# Example:
#
# ACLU(American Civil Liberties Union)
#
# Will become:
#
# <acronym title="American Civil Liberties Union">ACLU</acronym>
#
# == Adding Tables
#
# In Textile, simple tables can be added by seperating each column by
# a pipe.
#
# |a|simple|table|row|
# |And|Another|table|row|
#
# Attributes are defined by style definitions in parentheses.
#
# table(border:1px solid black).
# (background:#ddd;color:red). |{}| | | |
#
# == Using RedCloth
#
# RedCloth is simply an extension of the String class, which can handle
# Textile formatting. Use it like a String and output HTML with its
# RedCloth#to_html method.
#
# doc = RedCloth.new "
#
# h2. Test document
#
# Just a simple test."
#
# puts doc.to_html
#
# By default, RedCloth uses both Textile and Markdown formatting, with
# Textile formatting taking precedence. If you want to turn off Markdown
# formatting, to boost speed and limit the processor:
#
# class RedCloth::Textile.new( str )
class RedCloth < String
VERSION = '3.0.4'
DEFAULT_RULES = [:textile, :markdown]
#
# Two accessor for setting security restrictions.
#
# This is a nice thing if you're using RedCloth for
# formatting in public places (e.g. Wikis) where you
# don't want users to abuse HTML for bad things.
#
# If +:filter_html+ is set, HTML which wasn't
# created by the Textile processor will be escaped.
#
# If +:filter_styles+ is set, it will also disable
# the style markup specifier. ('{color: red}')
#
attr_accessor :filter_html, :filter_styles
#
# Accessor for toggling hard breaks.
#
# If +:hard_breaks+ is set, single newlines will
# be converted to HTML break tags. This is the
# default behavior for traditional RedCloth.
#
attr_accessor :hard_breaks
# Accessor for toggling lite mode.
#
# In lite mode, block-level rules are ignored. This means
# that tables, paragraphs, lists, and such aren't available.
# Only the inline markup for bold, italics, entities and so on.
#
# r = RedCloth.new( "And then? She *fell*!", [:lite_mode] )
# r.to_html
# #=> "And then? She <strong>fell</strong>!"
#
attr_accessor :lite_mode
#
# Accessor for toggling span caps.
#
# Textile places `span' tags around capitalized
# words by default, but this wreaks havoc on Wikis.
# If +:no_span_caps+ is set, this will be
# suppressed.
#
attr_accessor :no_span_caps
#
# Establishes the markup predence. Available rules include:
#
# == Textile Rules
#
# The following textile rules can be set individually. Or add the complete
# set of rules with the single :textile rule, which supplies the rule set in
# the following precedence:
#
# refs_textile:: Textile references (i.e. [hobix]http://hobix.com/)
# block_textile_table:: Textile table block structures
# block_textile_lists:: Textile list structures
# block_textile_prefix:: Textile blocks with prefixes (i.e. bq., h2., etc.)
# inline_textile_image:: Textile inline images
# inline_textile_link:: Textile inline links
# inline_textile_span:: Textile inline spans
# glyphs_textile:: Textile entities (such as em-dashes and smart quotes)
#
# == Markdown
#
# refs_markdown:: Markdown references (for example: [hobix]: http://hobix.com/)
# block_markdown_setext:: Markdown setext headers
# block_markdown_atx:: Markdown atx headers
# block_markdown_rule:: Markdown horizontal rules
# block_markdown_bq:: Markdown blockquotes
# block_markdown_lists:: Markdown lists
# inline_markdown_link:: Markdown links
attr_accessor :rules
# Returns a new RedCloth object, based on _string_ and
# enforcing all the included _restrictions_.
#
# r = RedCloth.new( "h1. A <b>bold</b> man", [:filter_html] )
# r.to_html
# #=>"<h1>A &lt;b&gt;bold&lt;/b&gt; man</h1>"
#
