Glimmer Calculator

Glimmer Calculator on Mac

Glimmer Calculator on Windows

Glimmer Calculator on Linux

Glimmer Calculator on Opal (Web)

Glimmer Calculator is a sample desktop GUI application built with Glimmer DSL for SWT (JRuby Desktop Development GUI Library).

Architectural Pattern is MVP (Model View Presenter) thanks to Glimmer data-binding support.

Glimmer Calculator was developed test-first following TDD (Test Driven Development) after Glimmer Scaffolding.

Design Patterns discovered in the process were Facade (Presenter) and Command Pattern.

Here are the calculator commands under the models directory:

Download Glimmer Calculator v1.1.4 DMG for Mac

Download Glimmer Calculator v1.1.1 MSI for Windows

Download Glimmer Calculator v1.1.4 GEM for Linux

Visit Glimmer Calculator v1.1.2 WEB for Opal

• Mac: Tested and packaged for Mac. (Download Here)
• Windows: Tested and packaged for Windows. (Download Here)
• Linux: Tested and packaged for Linux (Follow setup instructions to install gem and run calculator command)
• Opal (Web): Tested with Glimmer DSL for Opal and deployed to Heroku. Visit https://glimmer-cs-calculator-server.herokuapp.com

• JRuby 9.2.11.1 (supporting Ruby 2.5.x syntax) (find at https://www.jruby.org/download)
• Java SE Runtime Environment 7 or higher (find at https://www.oracle.com/java/technologies/javase-downloads.html)

Install Calculator gem by running (jgem, jruby -S gem, or gem directly if you have RVM):

jgem install glimmer-cs-calculator

Afterwards, you may run calculator to bring up the calculator:

calculator

Note: If you cloned this project and bundle installed, you may invoke via bin/calculator instead.

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

gem 'glimmer-cs-calculator', '1.1.4'

Run:

jruby -S bundle

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

The app Rails server lives under: server/glimmer-cs-calculator-server

It is deployed to Heroku at: https://glimmer-cs-calculator-server.herokuapp.com

Setup instructions from Glimmer DSL for Opal were followed in creating the Rails server.

This is the content of app/assets/javascripts/application.rb:

require 'glimmer-dsl-opal'

Document.ready? do
  require 'glimmer-cs-calculator/launch'
end

As you can see, Glimmer Calculator works as is by adding one require statement without needing to change a single line of its code thanks to Glimmer DSL for Opal.

CSS can be applied externally in Rails onto any Rails Route serving an Opal app.

TODO.md

CHANGELOG.md

• 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.
