Lecture-Specific

Introduction

  • For Linux and variants, use the Ruby Version Manager, RVM.
  • Ruby Homepage. For Windows installations, see RubyInstaller. I find that Rails Installer lags behind this, so I don't use it.
  • Ruby Doc.
  • Ruby development in Windows is doable, but I don't think it's a friendly environment. See Ruby in Twenty Minutes for a refresher.
  • If you want debugging support in Windows, such as in RubyMine or Eclipse, you'll also need DevKit to compile. Documentation. Under Step 5: Test Installation, replace the call for rubygems with ruby under 1.9.2.
  • RubyGems Manuals. See the User's Guide, particularly Chapter 3.
  • Try Ruby. No really, tryruby.

Testing

Too many testing frameworks (what's the testing framework of the day, these days), including: RSpec, Cucumber, Test/Unit (go directly to list of Assertions), Test/Spec and Shoulda.

Gems

Update the system itself (especially if using RubyMine and Ruby 1.9.2):

 gem update --system

Otherwise, RubyMine will throw errors.

See the RubyGems Manuals. Gem installation without RubyDoc:

 gem --no-ri --no-rdoc

If you've already installed ri and rdoc

 rm -r `gem env gemdir`/doc

Or to make option default, you can edit your gemrc file (StackOverflow). On Windows 7, this is C:\ProgramData\gemrc. Add gem: --no-ri --no-rdoc.

Obligatory reference to GnuWin. See Chapter 3 for Gem deployment.

RubyMine

Deployment

  • Heroku DevCenter.
  • It seems that you'll need to learn Git. And I just learned Subversion. Git for Windows isn't nearly as mature as the other platforms, unfortunately (preview), so use the portable version for now until it matures.
  • Heroku, the Ruby Cloud as a Platform Service. Their quick start guide requires that you know both Ruby and Git.

Rails

 gem 'execjs'
 gem 'therubyracer'
  • Cucumber requires ANSICON on Windows.

Books

There are a few good books on Ruby:
