Amrita2 is a XML/HTML template library for Ruby. I released a new version 1.9.6 as BETA1 for 2.0. Get it from [http://amrita2.rubyforge.org/](http://amrita2.rubyforge.org/) I reduced undocumented features and refactored much to prepare the comming stable release. And … - added gemspec and make it Rails plugin - simplified the ERB processing feature - new feature for setting two attributes (like class=‘odd’ and class=‘even’) alternately Now Amrita2 template can contain ERB source in it. ```
nameauthor
'><%= $_.name %> ]]>
``` CDATA in element will be evaluated as many times as number of ‘languages’ data. And each item will be set to ‘$\_’ before ERB evaluating. See this page for detail. How to use Amrita2 with Ruby On Rails [http://amrita2.rubyforge.org/Rails.html](http://amrita2.rubyforge.org/Rails.html) And this method setup Template to insert two attributes alternately. def languages\_setup\_template(template) tmpl = Amrita2::TemplateText.new(template) tmpl.use\_erb(binding) tmpl.element\_option[:languages] = { :mv\_attr=\> { :class=\>%w(odd even) } } tmpl end This template produces output like this. | name | author | | --- | --- | | [Ruby](http://www.ruby-lang.org/) | matz | | [perl](http://www.perl.com/) | Larry Wall | | [python](http://www.python.org/) | Guido van Rossum | ---

Yes, RoR separates view from model completely. But ERB template contains both VIEW PRESENTATION and VIEW LOGIC. Amrita2 and some other template system like Kwartz, XTemplate, SikiTemplate, misen, try to separate VIEW PRESENTATION from VIEW LOGIC. [http://www.rubygarden.org/ruby?HtmlTemplates](http://www.rubygarden.org/ruby?HtmlTemplates) There are cases at which ERB is not enough - VIEW LOGICs must be tested separately - Multi language (international) VIEW PRESENTATIONs share same VIEW LOGICs - want to design or check VIEW PRESENTATION staticaly without RoR environment And Amrita2 makes both VIEW PRESENTATION and VIEW LOGIC more decralative than ERB. I think Decralative code is easier to write, understand, modify, test than procedural code in ERB template. I think ERB is good for default template system for RoR. But we need alternative and that’s what plugin is for. – Taku Nakajima ---

Please, let’s not get into the same argument again. Let’s say so - templating systems are different, and serve different needs. It’s very good that Rails supports view drivers and that we now have 3 different ways to do templating in Rails. – Julian ‘Julik’ Tarkhanov me at julik.nl ---

I have been waiting for this ever since day 1 of using Rails. Just like how I hate writing scriptlets in JSP’s and putting PHP code in my HTML. I really didn’t like the use of Ruby code in my view templates. Thanks for making and sharing this plugin! I really hope one of these templating systems become part of the framework.
