ngrep - asynchronous grep

Copyright (C) 2011 by Maciej Małecki

MIT License (see LICENSE file)

ngrep does what grep does, but asynchronously.

Installation

As an executable

npm -g install ngrep

As a library

npm install ngrep

Usage

As an executable

To grep directory dir for string foo: ngrep foo dir (it couldn't get any simpler than that).

It can also grep files, but this is just slower than regular grep: ngrep foo file.

As a library

To grep directory dir for RegExp /foo/g:

var ngrep = require('ngrep');
ngrep(/foo/g, 'dir', function (result) {
  console.log(result.file + ': ' + console.context);
});
