h1. RedCloth


h2. Humane text for Ruby

RedCloth is a module for using Textile in Ruby.  Textile is a text 
format.  A very simple text format.  Another stab at making readable 
text that can be converted to HTML.

RedCloth is also based on PyTextile, which is: Copyright (c) 2003, "Mark

h2. About Version 2.0

Last year, a new version of Textile was released for PHP.  This 2.0 
version allowed specification of style attributes and element 
alignments.  Below, is a header element with a green font coloring added.

<pre>
  h2{color:green}. This is a title
</pre>

You can also add elements ids, classes, and language settings.

<pre>
  h2(class)
  h2(#id)
  h2[language]
</pre>

RedCloth 2.0 has been completely recoded and tested with Ruby versions 
1.8.0 and 1.6.8.  There are some outstanding bugs with using RedCloth in 
1.6.8, but I'm pushing it out the door anyway.  Hopefully, I can get 
some further revisions up in the coming weeks.

<http://www.textpattern.com/help/?item=attributes>h2. Installing RedCloth

To install RedCloth via raa-install:

<pre>
  raa-install -i redcloth
</pre>

Or "download 
RedCloth":http://prdownloads.sourceforge.net/yaml4r/redcloth-2.0.tar.gz 
and simply run the install.rb like so:

<pre>
  ruby install.rb config
  ruby install.rb setup
  sudo ruby install.rb install
</pre>


h2. Using RedCloth

The RedCloth class is an extension of Ruby's String class. Use it like 
you would a String:

<pre>
  >> r = RedCloth.new "*strong text* and _emphasized text_"
  => "*strong text* and _emphasized text_"
  >> r.gsub!( 'text', 'words' )
  => "*strong words* and _emphasized words_"
</pre>

To generate HTML from your RedCloth object, use the @RedCloth#to_html@ 
method:

<pre>
  >> r.to_html
  => "<p><strong>strong words</strong> and <em>emphasized words</em></p>"
</pre>


h2. The Textile language

See the "Textile home page":http://www.textism.com/tools/textile/ for 
details on the Textile language.
