My issues with Modules

In researching topics for RailsCasts I often read code in Rails and other gems. This is a great exercise to do. Not only will you pick up some coding tips, but it can help you better understand what makes code readable.

A common practice to organize code in gems is to divide it into modules. When this is done extensively I find it becomes very difficult to read. Before I explain further, a quick detour on instance_eval.

You can find instance_eval used in many DSLs: from routes to state machines. Here's an example from Thinking Sphinx.

class Article < ActiveRecord::Base
View Rakefile
require 'rubygems'
require 'bundler'
require './application'
namespace :assets do
desc 'compile assets'
task :compile => [:compile_js, :compile_css] do
View gist:2d6a3cdf447a123ab4e2
Services.factory("LawnchairFactory", function($window, $log, $parse) {
return function(name, config) {
var collection = {};
var array = [];
var isArray = config && config.isArray;
var idGetter = $parse((config && config.entryKey) ? config.entryKey : "id");
var transformSave = (config && config.transformSave) ? config.transformSave : angular.identity;
var transformLoad = (config && config.transformLoad) ? config.transformLoad : angular.identity;
function getEntryId(entry){

Environment variables in Jekyll templates

This is one way to pass some data (API tokens, etc.) to your Jekyll templates without putting it in your _config.yml file (which is likely to be committed in your GitHub repository).

Copy the environment_variables.rb plugin to your _plugins folder, and add any environment variable you wish to have available on the site.config object.

In a Liquid template, that information will be available through the site object. For example, _layouts/default.html could contain:

View Vagrantfile
# -*- mode: ruby -*-
# vi: set ft=ruby :
WORKSPACE_ROOT = "/Users/grockit/workspace"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| = "saucy-i386"
config.vm.box_url = ""
