Override console.log to print line number ( and filename ) (sometimes helpful in nodejs debugging)

overridelog.js

_log = console.log;
global.console.log = function() {
	var traceobj = new Error("").stack.split("\n")[2].split(":");
	var file = traceobj[0].split(process.env.PWD + '/')[1];
	var line = traceobj[1];
	var new_args = [file + ":" + line + " >>"];
	new_args.push.apply(new_args, arguments);
	_log.apply(null, new_args);
};

This solved my problem perfectly!
Now I just need to understand it all! 👍

Nice trick but the stack property of en Error object is tagged as "Non-standard". I would check if Error("").stack returns as undefined and work around with a default fallback if it is.
