nRake is now the subject of a Microsoft case study. Check it out here:

UPDATE: Now on the Microsoft Case Study site.

During the RORO hack night last Wednesday, Ryan Bigg (@ryanbigg) and I worked on a Rails Refactor, something I've been meaning to get going for a long time.

How often have you wasted time doing renames in rails? Sure it's hard to automate everything without understanding the code, but there sure are a lot of mechanical steps that you can easily automate. Ryan and I took on controller renames and got a fair way in the few hours we spent on the night.

Code is on github

To rename a controller:
$ rails_refactor.rb rename OldController NewController

• renames controller file & class name in file
• renames controller spec file & class name in file
• renames view directory
• renames helper file & module name in file
• updates routes

To rename a controller action:
$ rails_refactor.rb rename DummyController.old_action new_action

• renames controller action in controller class file
• renames view files for all formats

Looking to extend it with model renames, and then more complex refactoring.

While comparing Dates and Times in Rails (both 2.3 and 3), I came across an odd behaviour:

>> Time.parse("Mon, 26 Jul 2010 9:59") == Date.new(2010, 7, 26)
=> false
>> Time.parse("Mon, 26 Jul 2010 10:00") == Date.new(2010, 7, 26)
=> true
>> Time.parse("Mon, 26 Jul 2010 10:01") == Date.new(2010, 7, 26)
=> false

Also

>> Date.new(2010, 7, 26) == Time.parse("Mon, 26 Jul 2010 10:00")
=> false (Rails 2.3)
=> nil (Rails 3)
>> Date.new(2010, 7, 26) == Time.parse("Mon, 26 Jul 2010 0:00")
=> false (Rails 2.3)
=> nil (Rails 3)


Tonight, we'll be having the RORO hack night in the ThoughtWorks Sydney office, with a focus on open source projects (your own or contributing). A patch for this date/time behaviour might be an interesting area to pursue.
