Hi all,
I have released Erubis 2.2.0.
http://www.kuwata-lab.com/erubis
http://www.kuwata-lab.com/erubis/CHANGES
Erubis is another implementation of eRuby.
Features:
* Very fast, almost three times faster than ERB and
even ten percent faster than eruby (implemented in C)
* Support multi-language
(Ruby,PHP,C,Java,Scheme,Perl,Javascript)
* Auto escaping support
* Auto trimming spaces around '<% %>'
* Embedded pattern changeable (default '<% %>')
* Context object available and easy to combine eRuby
template with YAML datafile or Ruby script
* Easy to extend in subclass
* Ruby on Rails support
See users' guide (erubis_2.2.0/doc/users-guide.html)
for details.
$$ Enhancements
* Performance tuned up. Release 2.2.0 works about 8 percent faster
than 2.1.0.
As a result, Erubis works more than 10 percent faster than eruby.
(eruby is the extension module of eRuby written in C.)
* Support of Ruby on Rails improved.
If you want to use Erubis with Ruby on Rails, add the following
code
into your 'config/environment.rb' and restart web server.
This will set Erubis as eRuby compiler in Ruby on Rails instead of
ERB.
···
--------------------
require 'erubis/helpers/rails_helper'
#Erubis::Helpers::RailsHelper.engine_class = Erubis::Eruby
#Erubis::Helpers::RailsHelper.init_properties = {}
#Erubis::Helpers::RailsHelper.show_src = true
--------------------
Methods 'capture()' and 'content_for()' of
ActionView::Helpers::CaptureHelper
are available. Methd ActionView::Helpers::TextHelper#concat() is
also available.
If Erubis::Helpers::RailsHelper.show_src is ture, Erubis prints
converted
Ruby code into log file (such as 'log/development.log'). This is
for debug.
* Erubis::Engine.load_file(filename) creates cache file (filename +
'.cache') automatically if cache file is old or not exist.
Caching makes Erubis about 40-50 percent faster.
ex.
--------------------
require 'erubis'
eruby = Erubis::Eruby.load_file('example.rhtml')
## cache file 'example.rhtml.cache' is created automatically
--------------------
* Command-line option '-f datafile' can take Ruby script ('*.rb')
as well as YAML file ('*.yaml' or '*.yml').
ex.
====================
$ cat context.rb
@title = 'Example'
@list = %w[AAA BBB CCC]
$ cat example.rhtml
<h1><%= @title %></h1>
<ul>
<% for item in @list %>
<li><%= item %></li>
<% end %>
</ul>
$ erubis -f context.rb example.rhtml
<h1>Example</h1>
<ul>
<li>AAA</li>
<li>BBB</li>
<li>CCC</li>
</ul>
====================
* New command-line option '-c context' support. It takes context
string
in YAML inline style or Ruby code style.
ex. YAML inline style
====================
$ erubis -c '{title: Example, list: [AAA, BBB, CCC]}'
example.rhtml
====================
ex. Ruby style
====================
$ erubis -c '@title="Example"; @list=%w[AAA BBB CCC]'
example.rhtml
====================
* New command-line option '-z' (syntax checking) support. It is
similar
to 'erubis -x file.rhtml | ruby -wc', but it can take several
filenames.
ex.
====================
$ erubis -z app/views/*/*.rhtml
Syntax OK
====================
* New constant Erubis::VERSION added.
$$ Changes
* Class Erubis::Eruby changed to include
Erubis::StringBufferEnhancer
instead of Erubis::ArrayBufferEnhancer.
This is for Ruby on Rails support.
ex.
====================
$ cat example.rhtml
<ul>
<% for item in @list %>
<li><%= item %></li>
<% end %>
</ul>
$ erubis -x example.rhtml
_buf = ''; _buf << '<ul>
'; for item in @list
_buf << ' <li>'; _buf << ( item ).to_s; _buf << '</li>
'; end
_buf << '</ul>
';
_buf.to_s
====================
* Erubis::StringBufferEnhancer#add_postamble() prints "_buf.to_s"
instead of "_buf".
This is useful for 'erubis -x file.rhtml | ruby -wc'.
* Command-line option '-T' is removed. Use '--trim=false' instead.
* License is changed to MIT License.
* Embedded pattern '<%- -%>' can be handled.
