Mustache is written and maintained by Chris Wanstrath. See: github.com/defunkt/mustache
When a scope argument is provided to MustacheTemplate#render, the instance variables are copied from the scope object to the Mustache view.
# File lib/sinatra/tilt.rb, line 678 def evaluate(scope=nil, locals={}, &block) instance = @engine.new # copy instance variables from scope to the view scope.instance_variables.each do |name| instance.instance_variable_set(name, scope.instance_variable_get(name)) end # locals get added to the view's context locals.each do |local, value| instance[local] = value end # if we're passed a block it's a subview. Sticking it in yield # lets us use {{yield}} in layout.html to render the actual page. instance[:yield] = block.call if block instance.template = data unless instance.compiled? instance.to_html end
