Object.defineProperty(global, '__stack', {
	get: function () {
		var orig = Error.prepareStackTrace;
		Error.prepareStackTrace = function(_, stack){ return stack; };
		var err = new Error;
		Error.captureStackTrace(err, arguments.callee);
		var stack = err.stack;
		Error.prepareStackTrace = orig;
		return stack;
	}
});

Object.defineProperty(global, '__line', {
	get: function () {
		return __stack[1].getLineNumber();
	}
});

Object.defineProperty(global, '__basename', {
	get: function () {
		return require('path').basename(__stack[1].getFileName());
	}
});

Object.defineProperty(global, '__relative', {
	get: function () {
		return require('path').relative(process.cwd(), __stack[1].getFileName());
	}
});

Object.defineProperty(global, '__function', {
	get: function () {
		return __stack[1].getFunctionName();
	}
});

// Usage
console.log('[%s] %s - %s: line %s', new Date(), __relative, __function, __line);
