Clock Committing Style Guide

To allow us to automatically create a good quality changelog from our git history we recommend the following formats for commit messages.

The aim is to capture a reference to any ticket, card, or story that this commit contributes towards.

Because we are now using the Pivotal Tracker Webhook on some projects we suggest wrapping your commit message prefix with square brackets []

If you’re trying to pop a stash and Git won’t merge for you because you have changes in your index to the same file(s) (Git needs to use the index to do a merge at all), i.e.:

❯ gsp
error: Your local changes to the following files would be overwritten by merge:
	index.html
Please, commit your changes or stash them before you can merge.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

	define(function(require) {
	var React = require('react');

	var paramRegex = /__(\d)+/;
	var parser = new DOMParser();
	var errorDoc = parser.parseFromString('INVALID', 'text/xml');
	var errorNs = errorDoc.getElementsByTagName("parsererror")[0].namespaceURI;

	// turns the array of string parts into a DOM
	// throws if the result is an invalid XML document.

	{
	// The block has begun, we're in a new block scope. The TDZ for the "a" binding has begun

	var f = function() {
	// 2. Because f() is evaluated before `a` is actually declared,
	// an exception will be thrown indicating to the author that
	// `a` is not yet defined.
	console.log(a);
	};

	(function() {
	// Do not use this library. This is just a fun example to prove a
	// point.

	var Bloop = window.Bloop = {};

	var mountId = 0;
	function newMountId() {
	return mountId++;
	}

	# Stop on error
	set -e

	# Is brew needed?
	if [ -x "$(which brew)" ]; then
	echo Skipping brew
	else
	echo Installing brew
	ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
	fi

	// This event emitter emits events, but reserves the right to publish events to
	// for its creator. It uses a WeakMap for true encapsulation.

	const eesToEventMaps = new WeakMap();

	export default class EventEmitter {
	constructor(publisher) {
	const eventMap = Object.create(null);
	eesToEventMaps.set(this, eventMap);
