Tempeh

Tasty Ruby Templates

Tempeh is an opininated template engine for rendering html. It steals most of its ideas from Mote and the Herb fork. The motivation for a new library is the different rendering API that is designed for lazily binding a context with instance_eval for use with view components.

gem install tempeh

# ./templates/eat.tempeh
#
# % if hungry? %
#  Eat {{ food }}!
# % end %

require 'tempeh'

class View
  include Tempeh::Helpers

  def initialize(food)
    @food = food
  end

  def food
    @food
  end

  def hungry?
    true
  end
end

View.new('Tempeh').render('./templates/eat.tempeh') # Eat Tempeh!

% code %: Ruby to be evaluated but not outputted.

{{ code }}: Ruby that gets outputted as an escaped string. Safe for user input.

{{& code }}: Ruby that gets outputted as an unescaped string. Useful for rendering partials and other content that is guarenteed to be safe.

cache: Hash of compiled templates, populated by the render helper.

compile: Creates a proc from the the given string.

escape: HTML escapes the given string.

render: instance_eval's a template found at a file path. Saves the compiled template in Tempeh::cache for reuse.
