== About Erubis

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

• Very fast, almost three times faster than ERB and even 10% faster than eruby
• Multi-language support (Ruby/PHP/C/Java/Scheme/Perl/Javascript)
• Auto escaping support
• Auto trimming spaces around '<% %>'
• Embedded pattern changeable (default '<% %>')
• Enable to handle Processing Instructions (PI) as embedded pattern (ex. '')
• Context object available and easy to combine eRuby template with YAML datafile
• Print statement available
• Easy to extend and customize in subclass
• Ruby on Rails support

Erubis is implemented in pure Ruby. It requires Ruby 1.8 or higher. Erubis now supports Ruby 1.9.

See doc/users-guide.html for details.

== Installation

• If you have installed RubyGems, just type gem install erubis.

  $ sudo gem install erubis

• Else install abstract[http://rubyforge.org/projects/abstract/] at first, and download erubis_X.X.X.tar.bz2 and install it by setup.rb.

  $ tar xjf abstract_X.X.X.tar.bz2 $ cd abstract_X.X.X/ $ sudo ruby setup.rb $ cd .. $ tar xjf erubis_X.X.X.tar.bz2 $ cd erubis_X.X.X/ $ sudo ruby setup.rb

• (Optional) It is able to merge 'lib/**/*.rb' into 'bin/erubis' by 'contrib/inline-require' script.

  $ tar xjf erubis_X.X.X.tar.bz2 $ cd erubis_X.X.X/ $ cp /tmp/abstract_X.X.X/lib/abstract.rb lib $ unset RUBYLIB $ contrib/inline-require -I lib bin/erubis > contrib/erubis

== Ruby on Rails Support

Erubis supports Ruby on Rails. All you have to do is to add the following code into your 'config/environment.rb' and restart web server.

 require 'erubis/helpers/rails_helper'
 #Erubis::Helpers::RailsHelper.engine_class = Erubis::Eruby
 #Erubis::Helpers::RailsHelper.init_properties = {}
 #Erubis::Helpers::RailsHelper.show_src = nil

If Erubis::Helpers::RailsHelper.show_src is ture, Erubis prints converted Ruby code into log file ('log/development.log' or so). It is useful for debug.

== Exploring Guide

If you are exploring Eruby, see the following class at first.

• Erubis::TinyEruby (erubis/tiny.rb) -- the most simple eRuby implementation.
• Erubis::Engine (erubis/engine.rb) -- base class of Eruby, Ephp, Ejava, and so on.
• Erubis::Eruby (erubis/engine/eruby.rb) -- engine class for eRuby.
• Erubis::Converter (erubis/converter.rb) -- convert eRuby script into Ruby code.
