== 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. '<?rb ... ?>')
* 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 <tt>gem install erubis</tt>.

$ 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.
