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

module AuthHelper
  def http_login
    user = 'username'
    pw = 'password'
    request.env['HTTP_AUTHORIZATION'] = ActionController::HttpAuthentication::Basic.encode_credentials(user,pw)
  end
end

module AuthRequestHelper

This gist was writen in 2012 and it was solving specific problem in Rails & SimpleForm. Some fellow developers were pointing out this may be out dated concept. That's why I advise everyone to read comment section bellow to have a full grasp of alternative solutions

<h1>
	Stop the App Store upgrade prompt</h1>
<p>
	Fortunately I saved my copy of Skitch (version 1.0.12) after hearing <a href="http://twitter.com/danielpunkass">Daniel Jalkut</a> (developer at <a href="http://www.red-sweater.com/">Red Sweater Software</a> best known for <a href="http://www.red-sweater.com/marsedit/">MarsEdit</a> and <a href="http://www.red-sweater.com/fastscripts/">FastScripts</a>) mention that a brief stint with Skitch 2.0 had sent him back to Skitch version 1.</p>
<p>
	The only problem is that the Mac App Store app kept telling me that Skitch needs to be updated. I even went into my Purchases list and '&quot;hid&quot; Skitch, but still the App Store kept telling me that it wanted to update Skitch.</p>
<p>
	I seem to have found a solution, which was to quit Skitch.app, and then locate the app in /Applications/ using the Finder. Once there, I control-clicked on the app and chose &quot;Show Package Contents&quot;:</p>
