What's New in Edge Rails: Source Code Annotations

Posted by ryan

No, not the heavyweight annotations that you see in Java or C# – these are just a way to denote the todos and other mental reminders we often litter in our code comments:

1
2
3
4
5
6
7
8
9

class ContactsController < ApplicationController
  
  # TODO: factor out model verification to a filter
  # OPTIMIZE: optimize this
  # FIXME: it's broken
  def index
    ...
  end
end

With this new rake task we can now spit out a list of items we’ve annotated:

1
2
3
4
5

rake notes
app/controllers/contacts_controller.rb:
  * [ 3] [TODO] factor out model verification to a filter
  * [ 4] [OPTIMIZE] optimize this
  * [ 5] [FIXME] it's broken

You can also only list the annotations of a particular kind with rake notes:todo, rake notes:optimize and rake notes:fixme.

Update: JD has this tip to get this rake task installed in your non-edge Rails app. Thanks, JD!

    Someone’s been very busy lately! Lots going on in the world of Edge Rails.

    I love how lightweight and useful this is!

    Nice, very nice… I am used to this stuff from VisualStudio and love this feature. Now it will be available to rails… so nice ;)

    Could this perhaps be extracted from rails? I’d really like to use this for non-rails projects, too!

    hell, i’d love for it to be backported to a plugin for 1.2

    Nice. I already use that style of annotations, so this should be a huge help.

  7. JD – February 28, 2007 @ 02:38 PM

    You should be able to use this in any version of rails (just tested it in 1.2.2). Just do this from your rails root:

    svn export http://svn.rubyonrails.org/rails/trunk/railties/lib/tasks/annotations.rake lib/tasks/annotations.rake

    @JD: Thanks for the tip – gonna move it up to the post itself…

  9. Chris – March 06, 2007 @ 02:59 AM

    Yes, thank you, love it.

    This is a great addition, BUT something is broken in my app (running on Edge Rails). Whenever I run any rake task:

    $ rake db:migrate --trace
(in /home/.dijon/findfuel/releases/20070912040911)
rake aborted!
superclass mismatch for class Annotation
