# wrappy

Callback wrapping utility

## USAGE

```javascript

var wrappy = require("wrappy")

// var wrapper = wrappy(wrapperFunction)

// make sure a cb is called only once

// See also: http://npm.im/once for this specific use case

var once = wrappy(function (cb) {

  var called = false

  return function () {

    if (called) return

    called = true

    return cb.apply(this, arguments)

  }

})

function printBoo () {

  console.log('boo')

}

// has some rando property

printBoo.iAmBooPrinter = true

var onlyPrintOnce = once(printBoo)

onlyPrintOnce() // prints 'boo'

onlyPrintOnce() // does nothing

// random property is retained!

assert.equal(onlyPrintOnce.iAmBooPrinter, true)

```
