Global file-based templates

Tags: nitro 0.30 template

I’ve seen how to use embed HTML in a skin file to provide a global layout, but how can I use a text file for my global layout? I really want to avoid putting markup in my source code.

Thanks!

Template based elements... how about reading from a file.. and hiding the details...

Just brainstorming:

module TemplateBasedElement
  setting :template_dir, :default => 'element_templates', :doc => 'Template directory for Elements/Skins.'
  setting :template_ext, :default => '.xhtml'
  def self.included_with_parameters(base, options)
    file = File.join template_dir, base.to_s.pathize + template_ext
    
    if File.exists? file
      str = File.read file
      base.module_eval <<-EOE, __FILE__, __LINE__    
        def render_template
          #{str}
        end
        alias :render, :render_template
      EOE
    end
  end
end


class Skin < Nitro::Element
  is TemplateBasedElement
  
end

The template you had to change then would be: element_templates/skin.xhtml

That's the basic idea anyway, never tried it, so I'm not sure if it actually works. (something like that should be built into Nitro....)
