compile!(view) public

Compile a template. This method ensures a template is compiled just once and removes the source after it is compiled.

# File actionview/lib/action_view/template.rb, line 394
      def compile!(view)
        return if @compiled

        # Templates can be used concurrently in threaded environments
        # so compilation and any instance variable modification must
        # be synchronized
        @compile_mutex.synchronize do
          # Any thread holding this lock will be compiling the template needed
          # by the threads waiting. So re-check the @compiled flag to avoid
          # re-compilation
          return if @compiled

          mod = view.compiled_method_container

          instrument("!compile_template") do
            compile(mod)
          end

          @compiled = true
        end
      end
