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:

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/

Add to Gemfile this line

# gem 'ruby-debug-wrapper', :group => :development

Run bundler
```
# bundle install
```

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.
