Add callbacks

[tauren]

In my application's build process, I have the following tasks:

• compile - compiles coffeescript, stylus, etc.
• smoosh - smooshes everything
• deploy - deploys resources to the right places

As far as I can tell, smoosh doesn't have any sort of callbacks. This means I cannot detect when smoosh has finished so that I can start the deploy task.

What am I missing? The commands can be chained and run in sequence, so internally it must be running synchronously or using callbacks. Could these callbacks be exposed? Or could a new chained function be created, maybe after() or finished():

smoosh.after(functin() {})

I've tried the following to see if it is synchronous, and the text "Smoosh Done" prints before the smoosh output:

smoosh.make './smoosh.json'
sys.print 'Smoosh Done'

As a workaround, I'm doing this (in coffee-script):

{spawn, exec} = require 'child_process'
sys = require 'sys'
smoosh = require 'smoosh'

printOutput = (process) ->
  process.stdout.on 'data', (data) -> sys.print data
  process.stderr.on 'data', (data) -> sys.print data

smoosh = (cb) ->
  cmd = 'smoosh ./smoosh.json'
  tasks = exec cmd, (err, stdout, stderr) ->
    cb err,stdout,stderr
  printOutput(tasks)
