Subject: [ANN] Erubis 1.1.0 - an implementation of eRuby

I have released Erubis 1.1.0.
http://rubyforge.org/projects/erubis/

Erubis is an implementation of eRuby.
It has the following features:

* Auto sanitizing support
* Embedded pattern changeable (default '<% %>')
* Auto trimming spaces around '<% %>'
* Context object available
* Print statement available
* Faster mode support
* Easy to expand in subclass

Erubis is implemented in pure Ruby.  It requires Ruby 1.8 or higher.

Sample code (example.rb):
--------------------
## eRuby script
## ('<%= %>' is escaped and '<%== %>' is not escaped when XmlEruby)
input = <<END
<ul>
  <% for item in list %>
  <li><%= item %>
      <%== item %></li>
  <% end %>
</ul>
END

## create Eruby object
require 'erubis'
eruby = Erubis::XmlEruby.new(input)     # or Erubis::Eruby.new(input)

## get result
list = ['<aaa>', 'b&b', '"ccc"']
puts eruby.result(binding())
--------------------

result:
====================
$ ruby example.rb
<ul>
  <li>&lt;aaa&gt;
      <aaa></li>
  <li>b&amp;b
      b&b</li>
  <li>&quot;ccc&quot;
      "ccc"</li>
</ul>
====================

See doc/users-guide.html in archive for details.


: Enhancement from 1.0.1

  * '<%# .. %>' supported.  Erubis ignores '<%#  %>'.

  * New class PrintEruby and PrintXmlEruby available.
    These class enables you to embed print statement in eRuby
    (this feature is not supported in ERB).

    ex.  example.eb
    --------------------
    ## data and context
    list = ['aaa', 'bbb', 'ccc']
    context = { :list => list }

    ## eRuby script
    ## (use print statement instead of <%= item %>)
    input = <<-END
    <ul>
     <% for item in list %>
      <li><% print item %></li>
     <% end %>
    </ul>
    END

    ## create eruby and get result as string
    require 'erubis'
    eruby = Erubis::PrintEruby.new(input)
    str = eruby.evaluate(context)    # don't use result()!
    print str
    --------------------

    result:
    ====================
    $ ruby example.rb
    <ul>
      <li>aaa</li>
      <li>bbb</li>
      <li>ccc</li>
    </ul>
    ====================
  
Have fun!
