Robby on Rails

Last Friday, Greg Borenstein sent me a link to ZombieURL after it got launched. The folks at Bottlecap Labs took RubyURL and threw in Zombies… the rest you’ll have to see for yourself.

• don’t click this link

There… I warned you.

You can check out the source code for ZombieURL on GitHub

• http://github.com/bottlecaplabs/zombieurl/tree

You can also grab the underlying source code for RubyURL on GitHub.

• http://github.com/robbyrussell/rubyurl/tree/master

I’d love to see what other fun things people come up with to do with RubyURL.

A few weeks ago, I moved RubyURL from subversion to git. During that process, I decided to use my invite to GitHub and have decided to go ahead and open up the source code.

It’s currently a whopping 92 LOC with a 1:2.5 code to spec ratio. (I had a goal to keep is below 100 LOC)

• RubyURL on GitHub: http://github.com/robbyrussell/rubyurl
• Public Clone URL: git://github.com/robbyrussell/rubyurl.git

Feel free to grab it and help contribute. This has served almost 14 million redirects since August 2007 and is running on a Rails Boxcar.

To grab it with git.. run: git clone git://github.com/robbyrussell/rubyurl.git.

Feel free to submit tickets to the Rubyurl ticket system.

Enjoy!

UPDATE Ryan McGeary was kind enough to be the first person to help track down a bug and submit patches. :-)

When Chris Griffin saw this post, he wanted to do the same with RubyURL. Since the ShortURL gem was broken, I didn’t get a chance to dive into it. However, with the shorturl command now working again with RubyURL, we get QuickSilver and RubyURL working together really quickly.

First, you’ll need a recent version of the ShortURL gem installed.

sudo gem install shorturl

Then you will want to add the following to ~/Library/Scripts/rubyurl.scpt. You will need to create this file.

  #
  # Change accordingly if shorturl is not under /usr/bin/shorturl
  #
  set shorturl_cmd to "/opt/local/bin/shorturl" 

  tell application "Safari" 
      set original_url to URL of front document
  end tell

  set cmd to shorturl_cmd & " " & original_url

  set ruby_url to do shell script cmd
  set the clipboard to ruby_url as text
  beep

Then you can add this script to run through QuickSilver. For details, jump to the setup process on this post.

This will make it much easier to paste RubyURLs into my Twitter client, IRC, etc.

I’ll try to post a more thorough tutorial soon, but wanted to share in the meantime.

Earlier today, Vincent Foley was kind enough to hand over maitenance of the the ShortURL project on RubyForge to me. He first released it back in 2005, which I blogged about as RubyURL was the first shortening service that it supported (and is the default). Unfortunately, the release of RubyURL 2.0 broke backwards compatibility and Vincent wasn’t maintaining it anymore. So, earlier, I decided to patch this and got a new version released that now works with the current RubyURL site.

While working on the code, I decided to extend the compatible services to include moourl and urlTea.

These updates are available in ShortURL version 0.8.4.

Install the ShortURL gem

Installation is a snap… (like 99.7% of rubygems…)

  ~ > sudo gem install shorturl                                                                                                                                                                                                           Password:

Using ShortURL

The ShortURL gem provides the ShortURL library, which you can use from any Ruby application.

Using the ShortURL library

  ~ > irb                                                                                                                                                                                                                           
  irb(main):001:0> require 'rubygems'
  => true
  irb(main):002:0> require 'shorturl'
  => true
  irb(main):003:0> ShortURL.shorten( 'http://www.istwitterdown.com' )
  => "http://rubyurl.com/P9w" 

As you can see…it’s really straight forward.

Let’s try it with a few other services.

irb(main):004:0> ShortURL.shorten( 'http://www.istwitterdown.com', :moourl )
=> "http://moourl.com/fvoky" 
irb(main):005:0> ShortURL.shorten( 'http://www.istwitterdown.com', :tinyurl )
=> "http://tinyurl.com/2t3qmh" 

Using the shorturl command-line tool

Many people don’t know that ShortURL provides a command-line tool, which you can use after installing the gem.

  ~ > shorturl http://istwitterdown.com

My favorite part about this? My rbot plugin for RubyURL works again!

Happy URL-shortening!

If you previously followed my article, Installing Ruby on Rails and PostgreSQL on OS X, second edition and are now upgrading to OS X Leopard, you’ll want to make a few adjustments to your setup.

First of all, it’s great that Apple has decided to provide Ruby on Rails out of the box.

~ > gem list rails                                                                                                                                                                   
  *** LOCAL GEMS ***

  rails (1.2.3)
      Web-application framework with template engine, control-flow layer,
      and ORM.

How many gems does it come with?

~ > gem list|grep '^[a-z]'|wc -l                                                                                                                                                     
      29

It’s really great that Apple shipped Leopard pre-installed with 29 gems, especially if you don’t have your entire Rails stack setup already. In my case and for those that have followed my installation process, you don’t need to switch over to this new development stack (yet). I have a lot of time invested in my fully-functionaly MacPorts installation process (PostgreSQL, MySQL, RMagick, Subversion, Git, etc. Since this all working fine on my machine, I’m not ready to make the switch to Apple’s installation.

Don’t Fix it… if it’s not broken!

So, the the first thing that I did was modify my PATH environment variable, which has /usr/bin as the first path that it’ll look at when you try to run commands like ruby, mongrel_rails, gem, etc. You’ll want to modify this and prepend /opt/local/bin: to the front of PATH in your shell configuration. If you’re using bash, this would be… ~/.bashrc. If you’re using zshell like me, ~/.zshrc.

Now, when you start a new Terminal and run gem list, you’ll see all of the gems that you already have installed.

~ > gem list rails                                                                                                                                   < new-host

*** LOCAL GEMS ***

rails (1.2.5, 1.2.4, 1.2.3, 1.1.6)
    Web-application framework with template engine, control-flow layer,
    and ORM.

Back to my happy gems…

~ > gem list|grep '^[a-z]'|wc -l                                                                                                                                                              < new-host
      72

Great! Now I can get back to work and spend time playing with the new features in Finder, Mail.app, and iChat instead of installing all of the software dependencies that our development projects have. :-)

If you’re using the bookmarklet for RubyURL, you will want to update it with the latest version as there was apparently a bug in the JavaScript and some URLs would fail to redirect properly. Thanks to the help of Jerome, this is now fixed.

So, head over to RubyURL and update your bookmarket. Not sure what I’m talking about? Watch the video.
