Ruby Style Guide

This style guide is based on the one used by GitHub, but with some changes that make the code a tiny bit more readable.

  • Use soft-tabs with a two space indent.

  • Keep each line of code to a readable length. Unless you have a reason to, keep lines to fewer than 100 characters.

  • Never leave trailing whitespace.

Wrong onscreenready Example
View main.js
bb.init({
onscreenready: function (element, id) {
if (id == "main") {
var item = document.createElement('div');
item.setAttribute('data-bb-type','item');
item.setAttribute('data-bb-title','my title');
item.innerHTML = 'my description';
item.setAttribute('data-bb-img','foo.png');
document.getElementById('mylist').appendItem(item);
You can’t perform that action at this time.
