MineCraft + HipChat notification though nodejs. This is a quick little snippet that will let people in your hipchat server know that users have joined the minecraft server. Not sure what happens when the log file rotates.

hipchat-notify.js

Tail = require('tail').Tail;
tail = new Tail("latest.log");

HipChatClient = require('node-hipchat')
hipchat = new HipChatClient("*************************");

var loginPattern = /.*\[Server thread\/INFO\]: (.*) joined the game/;

tail.on("line", function(data) {
	var loginMatch = data.match(loginPattern);
	if (loginMatch) {
		console.log(loginMatch[1]);
		hipchat.postMessage({
			'room': '297355', 
			'from': 'MineCraft', 
			'message': 'Looks like '+loginMatch[1]+' just logged in.', 
			'notify': 0
		});
	}
});
