  "readme": "# EventEmitter2\n\nEventEmitter2 is an implementation of the EventEmitter found in Node.js\n\n## Features\n\n - Namespaces/Wildcards.\n - Times To Listen (TTL), extends the `once` concept with `many`.\n - Browser environment compatibility.\n - Demonstrates good performance in benchmarks\n\n```\nEventEmitterHeatUp x 3,728,965 ops/sec \\302\\2610.68% (60 runs sampled)\nEventEmitter x 2,822,904 ops/sec \\302\\2610.74% (63 runs sampled)\nEventEmitter2 x 7,251,227 ops/sec \\302\\2610.55% (58 runs sampled)\nEventEmitter2 (wild) x 3,220,268 ops/sec \\302\\2610.44% (65 runs sampled)\nFastest is EventEmitter2\n```\n\n## Differences (Non breaking, compatible with existing EventEmitter)\n\n - The constructor takes a configuration object.\n \n```javascript\n    var EventEmitter2 = require('eventemitter2').EventEmitter2;\n    var server = new EventEmitter2({\n      wildcard: true, // should the event emitter use wildcards.\n      delimiter: '::', // the delimiter used to segment namespaces, defaults to `.`.\n      newListener: false, // if you want to emit the newListener event set to true.\n      maxListeners: 20, // the max number of listeners that can be assigned to an event, defaults to 10.\n    });\n```\n\n - Getting the actual event that fired.\n\n```javascript\n    server.on('foo.*', function(value1, value2) {\n      console.log(this.event, value1, value2);\n    });\n```\n\n - Fire an event N times and then remove it, an extension of the `once` concept.\n\n```javascript\n    server.many('foo', 4, function() {\n      console.log('hello');\n    });\n```\n\n - Pass in a namespaced event as an array rather than a delimited string.\n\n```javascript\n    server.many(['foo', 'bar', 'bazz'], function() {\n      console.log('hello');\n    });\n```\n\n\n## API\n\nWhen an `EventEmitter` instance experiences an error, the typical action is\nto emit an `error` event. Error events are treated as a special case.\nIf there is no listener for it, then the default action is to print a stack\ntrace and exit the program.\n\nAll EventEmitters emit the event `newListener` when new listeners are\nadded.\n\n\n**Namespaces** with **Wildcards**\nTo use namespaces/wildcards, pass the `wildcard` option into the EventEmitter constructor.\nWhen namespaces/wildcards are enabled, events can either be strings (`foo.bar`) separated\nby a delimiter or arrays (`['foo', 'bar']`). The delimiter is also configurable as a \nconstructor option.\n\nAn event name passed to any event emitter method can contain a wild card (the `*` character).\nIf the event name is a string, a wildcard may appear as `foo.*`. If the event name is an array, \nthe wildcard may appear as `['foo', '*']`.\n\nIf either of the above described events were passed to the `on` method, subsequent emits such \nas the following would be observed...\n\n```javascript\n   emitter.emit('foo.bazz');\n   emitter.emit(['foo', 'bar']);\n```\n\n\n#### emitter.addListener(event, listener)\n#### emitter.on(event, listener)\n\nAdds a listener to the end of the listeners array for the specified event.\n\n```javascript\n    server.on('data', function(value1, value2, value3 /* accepts any number of expected values... */) {\n      console.log('The event was raised!');\n    });\n```\n\n```javascript\n    server.on('data', function(value) {\n      console.log('The event was raised!');\n    });\n```\n\n#### emitter.onAny(listener)\n\nAdds a listener that will be fired when any event is emitted.\n\n```javascript\n    server.onAny(function(value) {\n      console.log('All events trigger this.');\n    });\n```\n\n#### emitter.offAny(listener)\n\nRemoves the listener that will be fired when any event is emitted.\n\n```javascript\n    server.offAny(function(value) {\n      console.log('The event was raised!');\n    });\n```\n\n#### emitter.once(event, listener)\n\nAdds a **one time** listener for the event. The listener is invoked only the first time the event is fired, after which it is removed.\n\n```javascript\n    server.once('get', function (value) {\n      console.log('Ah, we have our first value!');\n    });\n```\n\n#### emitter.many(event, timesToListen, listener)\n\nAdds a listener that will execute **n times** for the event before being removed. The listener is invoked only the first time the event is fired, after which it is removed.\n\n```javascript\n    server.many('get', 4, function (value) {\n      console.log('This event will be listened to exactly four times.');\n    });\n```\n\n\n#### emitter.removeListener(event, listener)\n#### emitter.off(event, listener)\n\nRemove a listener from the listener array for the specified event. **Caution**: changes array indices in the listener array behind the listener.\n\n```javascript\n    var callback = function(value) {\n      console.log('someone connected!');\n    };\n    server.on('get', callback);\n    // ...\n    server.removeListener('get', callback);\n```\n\n\n#### emitter.removeAllListeners([event])\n\nRemoves all listeners, or those of the specified event.\n\n\n#### emitter.setMaxListeners(n)\n\nBy default EventEmitters will print a warning if more than 10 listeners are added to it. This is a useful default which helps finding memory leaks. Obviously not all Emitters should be limited to 10. This function allows that to be increased. Set to zero for unlimited.\n\n\n#### emitter.listeners(event)\n\nReturns an array of listeners for the specified event. This array can be manipulated, e.g. to remove listeners.\n\n```javascript\n    server.on('get', function(value) {\n      console.log('someone connected!');\n    });\n    console.log(console.log(server.listeners('get')); // [ [Function] ]\n```\n\n#### emitter.listenersAny()\n\nReturns an array of listeners that are listening for any event that is specified. This array can be manipulated, e.g. to remove listeners.\n\n```javascript\n    server.onAny(function(value) {\n      console.log('someone connected!');\n    });\n    console.log(console.log(server.listenersAny()[0]); // [ [Function] ] // someone connected!\n```\n\n#### emitter.emit(event, [arg1], [arg2], [...])\n\nExecute each of the listeners that may be listening for the specified event name in order with the list of arguments.\n\n## Test coverage\n\nThere is a test suite that tries to cover each use case, it can be found <a href=\"https://github.com/hij1nx/EventEmitter2/tree/master/test\">here</a>.\n\n## Licence\n\n(The MIT License)\n\nCopyright (c) 2011 hij1nx <http://www.twitter.com/hij1nx>\n\nPermission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the 'Software'), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
