Adding a Tilt Template

Thanks to Jan Thomä for adding this one.

If you need to add a new tilt handler to awestruct, it’s quite simple. Here are the list of instructions:

1. Add any gems to your Gemfile

   Gemfile

   gem 'typescript-node'

2. Create the tilt handler

   _ext/typescript_template.rb

   require 'tilt/template'
   require 'typescript-node'
   
   module Tilt
     class TypeScriptTemplate < Template
       self.default_mime_type = 'application/javascript'
   
       def prepare
         options[:filename] ||= file
       end
   
       def evaluate(scope, locals, &block)
         @output ||= TypeScript::Node.compile(data, '--target', 'ES5')
       end
     end
   end

3. Add the template via pipeline.rb

   require 'typescript'
   
   ::Tilt::register ::Tilt::TypeScriptTemplate, 'ts'
