date: 2011-04-01
|
|
enhancements:
|
|
|
|
- |
|
|
New option ':bufvar' supported to specify buffer variable name.
|
|
|
|
ex:
|
|
input = "Hello <%= name %>!"
|
|
eruby = Erubis::Eruby.new(input)
|
|
puts eruby.src
|
|
#=> _buf = ''; _buf << "Hello "; _buf << ( name ).to_s; _buf << '!';
|
|
|
|
eruby = Erubis::Eruby.new(input, :bufvar=>'@_out')
|
|
puts eruby.src
|
|
#=> @_out = ''; @_out << 'Hello '; @_out << ( name ).to_s; @_out << '!';
|
|
|
|
- |
|
|
New enhancer 'PrefixedLineEnhancer' which is a customizable version
|
|
of PercentLineEnhancer.
|
|
The difference between PrefixedLineEnhancer and PercentLineEnhancer is:
|
|
* You can indent Ruby statetment lines starting with '%'
|
|
* You can specify prefix character by :prefixchar option.
|
|
|
|
ex:
|
|
class MyEruby < Erubis::Eruby
|
|
include Erubis::PrefixedLineEnhancer
|
|
end
|
|
input = <<END
|
|
<ul>
|
|
% for item in @items
|
|
<li><%= item %></li>
|
|
% end
|
|
%% you can indent '%' lines
|
|
</ul>
|
|
END
|
|
eruby = MyEruby.new(input, :prefixchar=>'%') # default '%'
|
|
puts eruby.src
|
|
|
|
output:
|
|
_buf = ''; _buf << '<ul>
|
|
'; for item in @items
|
|
_buf << ' <li>'; _buf << ( item ).to_s; _buf << '</li>
|
|
'; end
|
|
% you can indent '%' lines
|
|
_buf << '</ul>
|
|
';
|
|
_buf.to_s
|
|
|

|
|
Add helper CGI script. See 'public_html/README.txt' for details.
|
|
|
|
- |
|
|
Rubinius is supported as first-class Ruby implementation.
|
|
|
|
- |
|
|
C++ support. Try '-l cpp' command-line option.
|
|
|
|
|
|
changes:
|
|
|
|
- |
|
|
Remove dependency to 'abstract' library.
|
|
You don't need to install 'abstract' gem.
|
|
|
|
- |
|
|
Erubis::Eruby#load_file() now sets cache file timestamp to the same
|
|
value as original eRuby file. For example, if you restore eRuby files
|
|
from backup, Erubis::Eruby#load_file() can detect it and generate
|
|
cache file again.
|
|
|
|
## generates cache file (A.rhtml.cache).
|
|
eruby = Erubis::Eruby.load_file('A.rhtml')
|
|
p File.mtime('A.rhtml') == File.mtime('A.rhtml.cache') #=> true

Rails 2.1 support. (special thanks José Valim)
|
|
|

|
|
|
|
- release: 2.6.0
|
|
date: 2008-05-05
|
|
enhancements:
|
|
|
|
- |
|
|
Improved support of Ruby on Rails 2.0.2.
|
|
New class ActionView::TemplateHandlers::Erubis is defined and
|
|
registered as default handler of *.html.erb and *.rhtml.
|
|
|
|
- |
|
|
'<%% %>' and '<%%= %>' are converted into '<% %>' and '<%= %>' respectively.
|
|
This is for compatibility with ERB.
|
|
|
|
ex1.rhtml:
|
|
<ul>
|
|
<%% for item in @list %>
|
|
<li><%%= item %></li>
|
|
<%% end %>
|
|
</ul>
|
|
|
|
result:
|
|
$ erubis ex1.rhtml
|
|
<ul>
|
|
<% for item in @list %>
|
|
<li><%= item %></li>
|
|
<% end %>
|
|
</ul>
|
|
|
|
- |
|
|
'<%= -%>' removes tail spaces and newlines.
|
|
This is for compatibiliy with ERB when trim mode is '-'.
|
|
'<%= =%>' also removes tail spaces and newlines, and this is
|
|
Erubis-original enhancement (cooler than '<%= -%>', isn't it?).
|
|
|
|
ex2.rhtml:
|
|
<div>
|
|
<%= @var -%> # or <%= @var =%>
|
|
</div>
|
|
|
|
result (version 2.6.0):
|
|
$ erubis -c '{var: "AAA\n"}' ex2.rhtml
|
|
<div>
|
|
AAA
|
|
</div>
|
|
|
|
result (version 2.5.0):
|
|
$ erubis -c '{var: "AAA\n"}' ex2.rhtml
|
|
<div>
|
|
AAA
|
|
|
|
</div>
|
|
|
|
- |
|
|
Erubis::Eruby.load_file() now allows you to change cache filename.
|
|
|
|
ex.
|
|
eruby = Erubis::Eruby.load_file("ex3.rhtml",
|
|
:cachename=>'ex3.rhtml.cache')
|
|
|
|

enhancements:
|
|
|
|
- |
|
|
Ruby on Rails 2.0 support.
|
|
If you are using preprocessing, notice that _?('foo.id') will be NG
|
|
because it contains period ('.') character.
|
|
|
|
--------------------
|
|
<!-- NG in Rails 2.0 -->
|
|
[%= link_to 'Edit', edit_user_path(_?('@user.id')) %]
|
|
[%= link_to 'Show', @user %]
|
|
[%= link_to 'Delete', @user, :confirm=>'OK?', :method=>:delete %]
|
|
|
|
<!-- OK in Rails 2.0 -->
|
|
<%= user_id = @user.id %>
|
|
[%= link_to 'Edit', edit_user_path(_?('user_id')) %]
|
|
[%= link_to 'Show', :action=>'show', :id=>_?('user_id') %]
|
|
[%= link_to 'Delete', {:action=>'destroy', :id=>_?('user_id')},
|
|
{:confirm=>'OK?', :method=>:delete} %]
|
|
--------------------
|
|
|
|
- |
|
|
(experimental)
|
|
Rails form helper methods for preprocessing are added.
|
|
These helper methos are available with preprocessing.
|
|
|
|
ex. _form.rhtml
|
|
--------------------
|
|
Name: <%= text_field :user, :name %>
|
|
Name: [%= pp_text_field :user, :name %]
|
|
--------------------
|
|
|
|
preprocessed:
|
|
--------------------
|
|
Name: <%= text_field :user, :name %>
|
|
Name: <input id="stock_name" name="stock[name]" size="30" type="text" value="<%=h @stock.name%>" />
|
|
--------------------
|
|
|
|
Ruby code:
|
|
--------------------
|
|
_buf << '
|
|
Name: '; _buf << ( text_field :stock, :name ).to_s; _buf << '
|
|
Name: <input id="stock_name" name="stock[name]" size="30" type="text" value="'; _buf << (h @stock.name).to_s; _buf << '" />
|
|
';
|
|
--------------------
|
|
|
|
This shows that text_filed() is called every time when rendering,
|
|
but pp_text_filed() is called only once when loading template,
|
|
so pp_text_field() with prepocessing is much faster than text_field().
|
|

|
enhancements:
|
|
|
|
- |
|
|
Add new section 'evaluate(context) v.s. result(binding)' to user's guide.
|
|
This section describes why Erubis::Eruby#evaluate(context) is recommended
|
|
rather than Erubis::Eruby#result(binding).
|
|
User's Guide > Other Topics > evaluate(context) v.s. result(binding)
|
|
http://www.kuwata-lab.com/erubis/users-guide.06.html#topics-context-vs-binding
|
|
|
|
- |
|
|
Add new command-line property '--docwrite={true|false}' to
|
|
Erubis::Ejavascript.
|
|
If this property is true then 'document.write(_buf.join(""));' is used
|
|
as postamble and if it is false then '_buf.join("")' is used.
|
|
Default is true for compatibility reason but it will be false in the
|
|
future release.
|
|
(This feature was proposed by D.Dribin. Thank you.)
|
|
|
|
bugfix:
|
|
|
|
- |
|
|
When using Erubis::Eruby#evaluate(), changing local variables in
|
|
templates have affected to variables accessible with TOPLEVEL_BINDING.
|
|
It means that if you change variables in templates, it is possible to
|
|
change variables in main program.
|
|
This was a bug and is now fixed not to affect to variables in main
|
|
program.
|
|
|
|
ex. template.rhtml
|
|
--------------------
|
|
<% for x in @items %>
|
|
item = <%= x %>
|
|
<% end %>
|
|
--------------------
|
|
|
|
ex. main-program.rb
|
|
--------------------
|
|
require 'erubis'
|
|
x = 10
|
|
items = ['foo', 'bar', 'baz']
|
|
eruby = Erubis::Eruby.new(File.read('template.rhtml'))
|
|
s = eruby.evaluate(:items=>items)
|
|
print s
|
|
$stderr.puts "*** debug: x=#{x.inspect}" #=> x="baz" (2.4.0)
|
|
#=> x=10 (2.4.1)
|
|
--------------------
|
|
|
|
- |
|
|
PercentLineEnhancer was very slow. Now performance problem is solved.
|
|
|
|

#
|
|
- release: 2.4.0
|
|
date: 2007-07-19
|
|
enhancements:
|
|
|
|
- |
|
|
Preprocessing is supported by Ruby on Rails helper.
|
|
Preprocessing makes Ruby on Rails application about 20-40 percent faster.
|
|
|
|
For example,
|
|
|
|
[%= link_to 'Show', :action=>'show', :id=>_?('@user.id') %]
|
|
|
|
is evaluate by preprocessor and expanded into the following
|
|
when template file is loaded.
|
|
|
|
<a href="/users/show/<%=@user.id%>">Show</a>
|
|
|
|
It means that link_to() is not called when template is rendered
|
|
and rendering speed will be much faster in the result.
|
|
|
|
See User's Guide for details.
|
|
|
|
- |
|
|
Erubis::Eruby#evaluate() (or Erubis::RubyEvaluator#evaluate()) now
|
|
creates Proc object from @src and eval it.
|
|
|
|
def evaluate(context=Context.new)
|
|
context = Context.new(context) if context.is_a?(Hash)
|
|
@_proc ||= eval("proc { #{@src} }", TOPLEVEL_BINDING, @filename || '(erubis)')
|
|
return context.instance_eval(&@_proc)
|
|
end
|
|
|
|
This makes evaluate() much faster when eruby object is reused.
|
|
|
|
- |
|
|
Erubis::Eruby#def_method() is supported.
|
|
This method defines ruby code as instance method or singleton metod.
|
|
|
|
require 'erubis'
|
|
s = "hello <%= name %>"
|
|
eruby = Erubis::Eruby.new(s)
|
|
filename = 'hello.rhtml'
|
|
|
|
## define instance method to Dummy class (or module)
|
|
class Dummy; end
|
|
eruby.def_method(Dummy, 'render(name)', filename) # filename is optional
|
|
p Dummy.new.render('world') #=> "hello world"
|
|
|
|
## define singleton method to an object
|
|
obj = Object.new
|
|
eruby.def_method(obj, 'render(name)', filename) # filename is optional
|
|
p obj.render('world') #=> "hello world"
|
|
|
|
This is equivarent to ERB#def_method().
|
|
|
|
- |
|
|
Erubis::XmlHelper.url_escape() and u() which is alias of url_escape()
|
|
are added.
|
|
This is equivarent to ERB#Util.url_escape().
|
|
|
|
|
|
bugfix:
|
|
- Help message was not shown when '-h' is specified. Fixed.
|
|
- 'def method()' was not availabe in template file. Fixed.
|
|
|
|
|
|
#
|
|
- release: 2.3.1
|
|
date: 2007-05-26
|
|
bugfix:
|
|
- A serious bug in 'helpers/rails_helper.rb' is fixed.
|
|
You must be update if you are using Erubis with Ruby on Rails.

|
|
|
|
|
#

|
- release: 2.3.0
|
|
date: 2007-05-23
|
|
enhancements:
|
|
- |
|
|
New class 'Erubis::FastEruby' is added.
|
|
It is a subclass of Erubis::Eruby and includes InterpolationEnhancer.
|
|
Erubis::FastEruby is compatible with and faster than Erubis::Eruby.
|
|
|
|
- |
|
|
New enhancer 'InterpolationEnhancer' is added.
|
|
This enhancer uses expression interpolation to eliminate method call
|
|
of String#<<. In the result, this enhancer makes Eruby a little faster.
|
|
|
|
--------------------
|
|
## Assume that input is '<a href="<%=url%>"><%=name%></a>'.
|
|
## Eruby convert input into the following code. String#<< is called 5 times.
|
|
_buf << '<a href="'; _buf << (url).to_s; _buf << '">'; _buf << (name).to_s; _buf << '</a>';
|
|
|
|
## When InterpolationEnhancer is used, String#<< is called only once.
|
|
_buf << %Q`<a href="#{url}">#{name}</a>`;
|
|
--------------------
|
|
|
|
- |
|
|
New enhancer 'ErboutEnhancer' is added.
|
|
ErboutEnhancer set '_erbout' as well as '_buf' to be compatible with ERB.
|
|
|
|
ex.
|
|
====================
|
|
$ cat ex.rhtml
|
|
<p>Hello</p>
|
|
$ erubis -x ex.rhtml
|
|
_buf = ''; _buf << '<p>Hello</p>
|
|
';
|
|
_buf.to_s
|
|
$ erubis -xE Erbout ex.rhtml
|
|
_erbout = _buf = ''; _buf << '<p>Hello</p>
|
|
';
|
|
_buf.to_s
|
|
====================
|
|
|
|
- |
|
|
[experimental]
|
|
New enhancer 'DeleteIndentEnhancer' is added.
|
|
This enhancer deletes indentation of HTML file.
|
|
|
|
ex.
|
|
====================
|
|
$ cat ex.rhtml
|
|
<div>
|
|
<ul>
|
|
<% for item in ['AAA', 'BBB', 'CCC'] %>
|
|
<li><%= item %></li>
|
|
<% end %>
|
|
</ul>
|
|
</div>

|
<li>AAA</li>
|
|
<li>BBB</li>
|
|
<li>CCC</li>
|
|
</ul>
|
|
</div>
|
|
====================
|
|
|
|
- |
|
|
Mod_ruby is supported (very thanks to Andrew R Jackson!).
|
|
See users-guide and 'contrib/erubis-run.rb' for details.
|
|
|
|
- |
|
|
New command-line option '-X', '-N', '-U', and '-C' are added.
|
|
These are intended to be a replacement of 'notext' command.
|
|
'-X' shows only ruby statements and expressions.
|
|
'-N' adds line numbers.
|
|
'-U' compress empty lines into a line.
|
|
'-C' removes empty lines.
|
|
|
|
|
|
changes:
|
|
|
|
- |
|
|
'helpers/rails_helper.rb' is changed to use ErboutEnhancer.
|
|
The following is an examle to use Erubis with Ruby on Rails.
|
|
|
|
File 'config/environment.rb':
|
|
----------------------------------------
|
|
require 'erubis/helpers/rails_helper'
|
|
#Erubis::Helpers::RailsHelper.engine_class = Erubis::Eruby # or Erubis::FastEruby
|
|
#Erubis::Helpers::RailsHelper.init_properties = {}
|
|
#Erubis::Helpers::RailsHelper.show_src = false # set true for debugging
|
|
----------------------------------------
|
|
|
|
- |
|
|
Command 'notext' has been removed. Use '-X', '-N', '-U', and '-C'
|
|
instead.
|
|
|
|
- |
|
|
Tab characters in YAML file are expaneded automatically.
|
|
If you want not to expand tab characters, add command-line optio '-T'.
|
|
|
|
- |
|
|
Benchmark scripts (benchmark/bench.*) are rewrited.
|
|
|
|
- |
|
|
Users-guide (doc/users-guide.html) is updated.
|
|
|
|
|
|
|
|
#
|
|
- release: 2.2.0
|
|
date: 2007-02-11
|
|
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').
|
|
|
|
- |
|
|
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.
|
|

|
date: 2006-09-23
|
|
enhancements:
|
|
- |
|
|
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>
|
|
--------------------
|
|
|
|

|
|
====================
|
|
$ 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 for debug of eRuby script.

klass = i % 2 == 0 ? 'odd' : 'even' ;
|
|
_buf << ( klass ).to_s;
|
|
_buf << Erubis::XmlHelper.escape_xml( item );
|
|
|
|
end ;
|
|
|
|

|
|
available wth HTML::Entities module.
|
|
