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.

See doc/users-guide.html for details.

Installation

If you have installed RubyGems, just type gem install —remote erubis.
```
  $ sudo gem install --remote erubis
```

Else install 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 = false

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.

Benchmark

‘benchmark/erubybenchmark.rb’ is a benchmark script of Erubis. Try ‘ruby erubybenchmark.rb’ in benchmark directory.
