ruby-debug-wrapper

When you debuging Rails 3 application (which uses Bundler) and trying different ruby versions with RVM you have following problem: you should switch your Gemfile between ruby-debug and ruby-debug19 gems to work with 1.8 and 1.9 Rubies. This gem solves the problem.

Follow this steps:

  1. Install ruby-debug gem for each ruby version you will use. For example:

    # rvm use system
    # gem install ruby-debug
    # rvm use ree@rails3
    # gem install ruby-debug -- --with-ruby-include=$rvm_path/src/ree-1.8.7-2010.02/
    # rvm use ruby-1.9.2-head@rails3
    # gem install ruby-debug19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-head/
  2. Add to Gemfile this line

    # gem 'ruby-debug-wrapper', :group => :development
  3. Run bundler

    # bundle install
  4. Now you can run server with debugger and switch ruby version without changing Gemfile each time:

    # rvm use system
    # script/rails s -u
    # rvm use ree@rails3
    # script/rails s -u
    # rvm use ruby-1.9.2-head@rails3
    # script/rails s -u

Tested with Rails 3.0.0.beta4 and MacOSX 10.6.4 only.

TODO

  • Tests.

  • Improve Bundler/RVM detection.

  • Automatically install ruby-debug or ruby-debug19 gem if missing.

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
