node-repl-callback

A really handy callback to use from the REPL console, and only from the REPL console. There is no reason to use this callback within the logic of an application.

Installation

npm install repl-callback

Usage

Quick and simple usage example:

node
> callback = require('repl-callback')
{ [Function: callback] generate: [Function: generate] }
> fs = require('fs')
...
> fs.readFile('somefile', callback.bind(a = {}))
undefined
> Done.
> a
{ ... }
> fs.readFile('somefile', callback.bind(b = { message: 'Different completion message!' }))
undefined
> Different completion message!
> b
{ ... }
> c = callback.generate()
[Function: callback]
> fs.readFile('somefile', c)
undefined
> Done.
> c
{ ... }
> d = callback.generate()
[Function: callback]
> d.message = 'Different completion message!'
'Different completion message!'
> fs.readFile('somefile', d)
undefined
> d
{ ... }
