Use require('ipc').send to communicate between browser and renderer. 2013-04-23 04:18:07 +00:00			`EventEmitter = require('events').EventEmitter`
Use camelCase not under_score, I forgot it's coffee script. 2013-04-27 11:13:24 +00:00			`ipc = process.atomBinding('ipc')`

small tune of IPC interface. 2013-04-23 12:57:14 +00:00			`@emit(args...)`

Clear listeners on process object when unloading. The process object is created under node context, and it will live through the reloading, so we are responsible for clearing the listeners to make sure resources are not leaked. 2013-05-04 13:52:14 +00:00			`window.addEventListener 'unload', (event) ->`

No more plan for ipc.sendSync in browser. I want the browser to be fully asynchronous, so sending synchronous messages from browser to renderer will be unacceptable. 2013-04-23 14:21:49 +00:00			`ipc.send('ATOM_INTERNAL_MESSAGE', 'message', args...)`
Add getRoutingID and getProcessID for window API. 2013-04-23 09:21:34 +00:00

Add ipc.sendSync in renderer. 2013-04-23 13:52:19 +00:00			`ipc.send('ATOM_INTERNAL_MESSAGE', args...)`

			`sendSync: (args...) ->`
Prefer event.returnValue to event.result for sync messages. 2013-09-20 13:24:04 +00:00			`msg = ipc.sendSync('ATOM_INTERNAL_MESSAGE_SYNC', 'sync-message', args...)`
