email template rendering

==========================

this will use derby-templates to render emails from files.

the controller is just a module with view functions attached to it, it can be an empty object otherwise.

index.coffee

{templates, contexts} = require 'derby-templates'
require 'derby-parsing'

util = require './util'

fs = require 'fs'

cache = {}

exports.createRenderer = (ns, parts, controller = util) ->
  views = new templates.Views()

  for name, file of parts
    path = "#{__dirname}/templates/#{ns}/#{file}"
    template = cache[path]
    if !template
      template = cache[path] = fs.readFileSync(path).toString()
    views.register "#{ns}:#{name}", template

  contextMeta = new contexts.ContextMeta({})

  return (ns, name, context = {}) ->
    view = views.find "#{ns}:#{name}"
    controller.model = {data: context}
    context = new contexts.Context(contextMeta, controller);
    return view?.get context
