How to create a Ruby gem that adds Rake tasks

Create a gem

One way to do this is to use bundler to scaffold our gem:

bundler gem my_gem

Add rake tasks to our gem

I prefer to put tasks meant to manage the gem itself in lib/tasks, and tasks the gem is meant to provide to gem users in lib/my_gem/tasks.

How to create small, unique tokens in Ruby

That is is basically a "fork" of blog article i'm constantly returning to. It seems that the blog is down:

• Original article
• Internet Archives

My choice: Dave Bass’s rand().to_s() trick

Dave Bass proposed this which I picked up for my implementation (here for an 8-chars token):

How to use MAMP with the mysql2 gem and Ruby 1.9.3-p194 via rbenv

Let's say you're a web developer who happens to work with both MAMP and Ruby when building different types of websites. Let's say you also like to keep your MySQL stuff in one place and don't like having to juggle both a local MySQL install as well as a MAMP MySQL install. Well, you can indeed connect your ruby apps to MAMP's MySQL. Here's a tutorial on how to do it.

Important! Before you do anything, download and install MAMP. MAMP Pro will work as well. At the time of this writing, MAMP 2.1.1 is the latest.

First, install Ruby via rbenv

1. Install homebrew
2. Install rbenv: brew install rbenv, follow any instructions homebrew gives you after the installation is complete.
