- 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 '<%=name%>'.
## Eruby convert input into the following code. String#<< is called 5 times.
_buf << ''; _buf << (name).to_s; _buf << '';
## When InterpolationEnhancer is used, String#<< is called only once.
_buf << %Q`#{name}`;
--------------------
- |
New enhancer 'ErboutEnhancer' is added.
ErboutEnhancer set '_erbout' as well as '_buf' to be compatible with ERB.
ex.
====================
$ cat ex.rhtml
Hello
$ erubis -x ex.rhtml
_buf = ''; _buf << 'Hello
';
_buf.to_s
$ erubis -xE Erbout ex.rhtml
_erbout = _buf = ''; _buf << 'Hello
';
_buf.to_s
====================
- |
[experimental]
New enhancer 'DeleteIndentEnhancer' is added.
This enhancer deletes indentation of HTML file.
ex.
====================
$ cat ex.rhtml
<% for item in ['AAA', 'BBB', 'CCC'] %>
- <%= item %>
<% end %>
$ erubis ex.rhtml
$ erubis -E DeleteIndent ex.rhtml
====================
- |
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
<%= @title %>
<% for item in @list %>
- <%= item %>
<% end %>
$ erubis -f context.rb example.rhtml
Example
====================
- |
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
<% for item in @list %>
- <%= item %>
<% end %>
$ erubis -x example.rhtml
_buf = ''; _buf << '
'; for item in @list
_buf << ' - '; _buf << ( item ).to_s; _buf << '
'; end
_buf << '
';
_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.
#
- release: 2.1.0
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)
'' as embedded pattern instead of '<% .. %>'.
example.rhtml
--------------------
--------------------
compile:
====================
$ erubis -x --pi example.rhtml
_buf = []; _buf << '
'; @list.each_with_index do |item, i|
klass = i % 2 == 0 ? 'odd' : 'even'
_buf << '
'; _buf << (item).to_s; _buf << ' |
'; end
_buf << '
';
_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.
example2.rhtml
--------------------
<% @list.each_with_index do |item, i| %>
<% klass = i % 2 == 0 ? 'odd' : 'even' %>
<%== item %> |
<% end %>
--------------------
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
====================
changes:
- 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.
