node-simple-router/src/uuid.coffee

Yet another minimalistic router for node.js

uuid = ->
  d = new Date().getTime()
  guid = "xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx".replace(/[xy]/g, (c) ->
    r = (d + Math.random() * 16) % 16 | 0
    d = Math.floor(d / 16)
    ((if c is "x" then r else (r & 0x7 | 0x8))).toString 16
  )
  guid

module?.exports = uuid
