Subject: [ANN] Radius 0.0.1 -- Powerful Tag-Based Templates

I am pleased to announce the immediate release of Radius 0.5.0.

Radius is a small, but powerful tag-based template language for Ruby
inspired by the template languages used in MovableType
<www.movabletype.org> and TextPattern <www.textpattern.com>. It uses
tags similar to XML, but can be used to generate any form of plain text
(HTML, e-mail, etc...).

This release is much more feature complete than previous releases with 
it's own domain language and support for nested tags.

 From the change log:

0.5.0
   * Created a DSL for tag definitions (introducing a DSL makes this
     version of Radiant incompatible with the last). The DSL has the
     following features:
     - full support for nested tags
     - global and local tag variables
     - Contexts can now be defined dynamically (instead of being
       subclassed)
     - see the QUICKSTART for more info
   * Many refactorings of the library and unit tests.
   * Changed the license to the MIT-LICENSE.
   * Updated documentation to reflect the changes.
   * Updated the version number to reflect the maturity of the code base.

Download:

Documentation:
   http://radius.rubyforge.org

Instalation:
   % gem install --remote radius

A small example:

   require 'radius'

   # Define tags on a context that will be available to a template:
   context = Radius::Context.new do |c|
     c.define_tag 'hello' do
       'Hello world'
     end
     c.define_tag 'repeat' do |tag|
       number = (tag.attr['times'] || '1').to_i
       result = ''
       number.times { result << tag.expand }
       result
     end
   end

   # Create a parser to parse tags that begin with 'r:'
   parser = Radius::Parser.new(context, :tag_prefix => 'r')

   # Parse tags and output the result
   puts parser.parse("A small example:\n" +
     '<r:repeat times="3">* <r:hello />!\n</r:repeat>')

Output:

   A small example:
   * Hello world!
   * Hello world!
   * Hello world!
