$ [ANN] Erubis 2.1.0 release - a fast eRuby implementation
I have released Erubis 2.1.0.
http://rubyforge.org/projects/erubis/
Erubis is a pure ruby implementation of eRuby.
Features:
* Very fast, almost three times faster than ERB and
even as fast as 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
* Print statement available
* Easy to extend in subclass
See users' guide (erubis_2.1.0/doc/users-guide.html)
for details.
Enhancements from 2.0:
* Ruby on Rails support. Add the following code to
your 'app/controllers/application.rb' and restart web server.
--------------------
require 'erubis/helper/rails'
suffix = 'erubis'
ActionView::Base.register_template_handler(suffix, Erubis::Helper::RailsTemplate)
#Erubis::Helper::RailsTemplate.engine_class = Erubis::EscapedEruby ## or Erubis::PI::Eruby
#Erubis::Helper::RailsTemplate.default_properties = { :escape=>true, :escapefunc=>'h' }
--------------------
And rename your view template as 'xxx.erubis'.
If you got the "(eval):10:in `render': no block given" error,
use '@content_for_layout' instead 'yield' in your layout template.
* Another eRuby engine (PIEngine) support. This engine doesn't
break HTML design because it uses Processing Instructions (PI)
'<?rb .. ?>' as embedded pattern instead of '<% .. %>'.
example.rhtml
--------------------
<table>
<?rb @list.each_with_index do |item, i| ?>
<?rb klass = i % 2 == 0 ? 'odd' : 'even' ?>
<tr class="@{klass}@">
<td>@!{item}@</td>
</tr>
<?rb end ?>
</table>
--------------------
compile:
====================
$ erubis -x --pi example.rhtml
_buf = []; _buf << '<table>
'; @list.each_with_index do |item, i|
klass = i % 2 == 0 ? 'odd' : 'even'
_buf << ' <tr class="'; _buf << Erubis::XmlHelper.escape_xml(klass); _buf << '">
<td>'; _buf << (item).to_s; _buf << '</td>
</tr>
'; end
_buf << '</table>
';
_buf.join
====================
* Add new command 'notext' which remove text part from eRuby
script and leaves only Ruby code.
This is very useful when debugging eRuby script.
example2.rhtml
--------------------
<html>
<body>
<table>
<% @list.each_with_index do |item, i| %>
<% klass = i % 2 == 0 ? 'odd' : 'even' %>
<tr class="<%= klass %>">
<td><%== item %></td>
</tr>
<% end %>
</table>
</body>
</html>
--------------------
command line example:
====================
$ notext example2.rhtml
_buf = [];
@list.each_with_index do |item, i| ;
klass = i % 2 == 0 ? 'odd' : 'even' ;
_buf << ( klass ).to_s;
_buf << Erubis::XmlHelper.escape_xml( item );
end ;
_buf.join
$ notext -nc example2.rhtml
1: _buf = [];
4: @list.each_with_index do |item, i| ;
5: klass = i % 2 == 0 ? 'odd' : 'even' ;
6: _buf << ( klass ).to_s;
7: _buf << Erubis::XmlHelper.escape_xml( item );
9: end ;
13: _buf.join
====================
* Add new enhance 'NoCode' which removes ruby code from
eRuby script and leaves only HTML text part.
It is very useful to validate HTML of eRuby script.
command-line example:
====================
$ erubis -x -E NoCode example2.rhtml
<html>
<body>
<table>
<tr class="">
<td></td>
</tr>
</table>
</body>
</html>
====================
Changes from 2.0:
* License is changed to LGPL.
* Command-line property '--escape=name' is renamed to
'--escapefunc=name'.
* When command-line option '-l perl' is specified, function
'encode_entities()' is used ad escaping function which is
available wth HTML::Entities module.
Bugfix:
* There is a certain pattern which makes Engine#convert()
too slow. Now Engne#convert() is fixed not to be slown.
* Command name is now displayed when '-h' is specified.
Have fun!

$ [ANN] Erubis 2.0.1 release - a fast eRuby implementation
I have released Erubis 2.0.0.
http://rubyforge.org/projects/erubis/
Erubis is a pure ruby implementation of eRuby.
This is a minor bugfix version.
$ [ANN] Erubis 2.0.0 release - a fast eRuby implementation
I have released Erubis 2.0.0.
http://rubyforge.org/projects/erubis/
Erubis is a pure ruby implementation of eRuby.
Features:
* Very fast, almost three times faster than ERB and
even as fast as eruby (implemented in C)
* Support multi-language

* Context object available and easy to combine eRuby
template with YAML datafile
* Print statement available
* Easy to extend in subclass
See users' guide (erubis_2.0.0/doc/users-guide.html)
for details.
Changes from 1.1:
* module 'PrintEnhancer' is renamed to 'PrintEnabledEnahncer'
* module 'FastEnhancer' and class 'FastEruby' is obsolete
(these are integrated with Eruby class)
* Eruby#evaluate() calls instance_eval() instead of eval()
* XmlEruby.escape_xml() is moved to XmlHelper.escape_xml()
* and so on
Enhancements from 1.1:
* multi programming language support
(Ruby,PHP,C,Java,Scheme,Perl,Javascript)
* many enhancer modules are added (see users' guide for details)
* class Eruby runs very fast because FastEnhancer module is
integrated into Eruby by default
* TinyEruby class (tiny.rb) is added
* and so on
If you are interested in Eruby internal, see the following classes
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.

$ Release 1.1.1 (2006-03-06)
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
* Auto trimming spaces around '<% %>'
* Embedded pattern changeable (default '<% %>')
* 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.
See doc/users-guide.html in archive for details.
: Enhancement from 1.1.0
* New command-line option '-x' supported.
This option prints Ruby source code of eRuby script coverted
and remove the last '_out' line.
This is more convenient than '-s' when validating with 'ruby -wc'.
example:
====================
$ cat foo.eruby
<% (1..3).each do |i| %>
i = <%= i %>
<% end %>
$ eruby -x foo.eruby
_out = ''; (1..3).each do |i|
_out << " i = "; _out << ( i ).to_s; _out << "¡Àn"
end
$ eruby -x foo.eruby | ruby -wc
Syntax OK
$ eruby -s foo.eruby
_out = ''; (1..3).each do |i|
_out << " i = "; _out << ( i ).to_s; _out << "¡Àn"
end
_out
$ erubis -s foo.rhtml | ruby -wc
-:4: warning: useless use of a variable in void context
Syntax OK
====================
$ Release 1.1.0 (2006-03-05)
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 using XmlEruby class)
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><aaa>
<aaa></li>
<li>b&b
b&b</li>
<li>"ccc"
"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
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!
