// + emit SIGINT, and handle "exit" event

var stdin = process.stdin;

// without this, we would only get streams once enter is pressed
stdin.setRawMode( true );

// resume stdin in the parent process (node app won't quit all by itself
// unless an error or process.exit() happens)
stdin.resume();

// i don't want binary, do you?
stdin.setEncoding( 'utf8' );

// on any data into stdin
stdin.on( 'data', function( key ){
  // ctrl-c ( end of text )
	if ( key === '\u0003' ) {
		// emulation of SIGINT event
		// make it uniform between windows and unix
		process.emit("SIGINT");
	}
	// write the key to stdout all normal like
	process.stdout.write(key);
});

// handle SIGINT, and exit
process.on("SIGINT", function(){
	console.error("Handle SIGINT event");
	process.exit(-1);
});

// last chance to hook into before node app exits
 
process.on("exit", function(){
	console.error("handle exit...");
	process.nextTick(function(){
		// no more events will be run from queue	
	});
});
