coffee-resque-retry
===================

Adds some retry options to coffee-resque.

Concept lifted from Ruby's resque-retry. Thanks lantins! (^_^)


To run specs:

  make test

Or, more simply:

  vows


Description:  

I've tried to just lightly wrap the function for creating
workers, but of course, you need a watcher to handle looking
for the scheduled tasks needed for delayed retries.

Usage:

  resque = require('coffee-resque').connect redisHostAndPort
  {createWorker,watcher} = require 'coffee-resque-retry'

  worker = createWorker resque, "some-queue-name"
      task_name:
        retry_limit: 2                
        retry_delay: 20 
        func: (arg1, arg2, cb) -> 
          doSomething arg1, arg2, (err, result) ->
            if err?
              cb new Error err
            else 
              cb result
      another_task:
        retry_limit: 6
        func: (arg, cb) -> 
          doSomethingElse arg, (err, result) ->
            if err?
              cb new Error err
            else 
              cb result


  watcher.start()

Now, wait for other code to enqueue tasks, and when you're
program is shutting down remember to call `watcher.stop()`
