Wildcard event-emitter proxy for nodejs.

Installation

Example

var Emitter = require('events').EventEmitter;
var events = require('wildcards');

var app = new Emitter;

events(app, 'user:*', function(event, user){
  console.log('  %s %s', event, user);
});

app.emit('foo');
app.emit('bar');
app.emit('user:logout', 'tobi');
app.emit('user:login', 'loki');
app.emit('user:login', 'jane');

wildcards's Issues

emit should be chainable

testcase.js

var Emitter = require('events').EventEmitter;
var events = require('wildcards');

var app = new Emitter;

events(app, 'foo*', function () {
  console.log(arguments);
});

app.emit('foo').emit('bar').emit('foo bar');

yields:

$ node testcase.js 
{ '0': 'foo' }
