JRB - Plain Ruby templates

JRB is a simple template handler that allows you to use plain Ruby files as templates. Use it when you're experimenting with your views. Use it if you have templates that don't have much markup. Or use it if you prefer to use HTML generators such as Crafty.

Synopsis

Add jrb to your Gemfile:

gem "jrb"

Now you can write Ruby templates whenever you like. JRB renders the last return value of your Ruby template.

# app/views/examples/hello.html.rb
"Hello world!"

For more complex scenarios, JRB exposes the method <<, aliased as write. It allows you to write directly to the output stream.

# app/views/examples/greeting.html.rb
write "Hello "
write @name
write "!"

JRB escapes HTML output by default.

# app/views/examples/escaping.html.rb
write "<html>".html_safe
write @unsafe_content
write "</html>".html_safe

JRB really shines when used in combination with HTML helpers such as those provided by Crafty.

# app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  helper Crafty::HTML::Basic
end

# app/views/examples/builder.html.rb
html do
  head do
    title "Hello"
  end
  body do
    div class: ["main", "content"] do
      p "Hello #{@name}!"
    end
  end
end
