watch and autocompile.jade and .coffee files when changed

autocompile.coffee

jade = require 'jade'
fs = require 'fs'
coffee = require 'coffee-script'
path = require 'path'
file = require 'file'


watch = (fname)->
  fs.watch fname, (event, filename)->

    if event == 'change'
      switch path.extname(filename)
        when '.jade'
          fs.readFile filename, (err, data)->
            res = "define(function(require) {
                jade = require('jade');
                return #{jade.compile(data, client: true)}
              })"
            fs.writeFile path.basename(filename, '.jade')+'.js', res

        when '.coffee'
          fs.readFile filename, (err, data)->
            data = data.toString()
            res = coffee.compile(data)
            fs.writeFile path.basename(filename, '.coffee')+'.js', res

file.walk './', (err, dirPath, dirs, files)->
  files.forEach (filename)->
    extname = path.extname(filename)
    if ['.jade', '.coffee'].indexOf(extname) != -1
      watch(filename)

Please not that .jade files get autocompiled in RequireJS/AMD format
