Glimmer Calculator

Glimmer Custom Shell

Calculator

Glimmer Calculator is a sample desktop GUI application built with Glimmer (Ruby Desktop Development Library).

It is developed test-first following TDD (Test Driven Development). Design Patterns discovered in the process were Presenter/Facade and Command Pattern.

Follows the MVP architectural pattern (Model View Presenter) thanks to Glimmer data-binding support.

Glimmer Custom Shell Reuse

To reuse Calculator as a Glimmer Custom Shell inside another Glimmer application, add the following to the application's Gemfile:

gem 'glimmer-cs-calculator', '1.0.2'

Run:

jruby -S bundle

And, then instantiate the Calculator custom shell in your Glimmer application via the calculator Glimmer DSL keyword.

Contributing to glimmer-cs-calculator

Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
Fork the project.
Start a feature/bugfix branch.
Commit and push until you are happy with your contribution.
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
