eurucamp 2013 - A recap. [Part I]
Some weeks a go some colleagues of mine and me were attending the eurucamp 2013 at the lovely Müggelsee in Berlin. Besides the nice location, the European Ruby Camp did not only provide tasty coffee but also a whole bunch of interesting talks and workshops. This article will summarize the most interesting parts.
Workshop: Up & Running with Ember.js
The first course I’ve attended has been the Ember.js workshop. Also this has been the first contact with the eurucamp wifi …
To be polite: It wasn’t super optimal ;-) So while listening to the speaker (Balint Erdi) I spent about 2 hours downloading Rails 4 :-/ In the end it turned out, that using my mobile phone’s hotspot was a better option.
As it was quite hard to actually follow Balint’s workshop without running the code he was explaining, I will just reference his notes of the talk.
Workshop: Native iOS development using RubyMotion
The second workshop was about RubyMotion. First, Marin Usalj provided a temporary RubyMotion executable for every attendee. That way it was a pleasure to participate in the workshop, without getting into any hassles related to downloads. Once everyone installed the package, Marin create a first simple application:
motion create test Create test Create test/.gitignore Create test/Rakefile Create test/app Create test/app/app_delegate.rb Create test/resources Create test/resources/Defaultemail@example.com Create test/spec Create test/spec/main_spec.rb
Its now possible to launch that application just by firing this:
cd test rake
This will basically compile the RubyMotion application and open it in the simulator. You should see an iPhone with a black screen now.
We went on by adding a root controller, which gets loaded in the application’s main entry point: The file
# app/app_delegate.rb class AppDelegate def application(application, didFinishLaunchingWithOptions:launchOptions) @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds) @window.rootViewController = RootViewController.new @window.makeKeyAndVisible true end end
# app/controllers/root_controller.rb class RootViewController < UIViewController def loadView self.view = UIView.alloc.initWithFrame(UIScreen.mainScreen.bounds) self.view.backgroundColor = UIColor.whiteColor add_buttons end def add_buttons # button = UIButton.alloc.initWithFrame([[100, 100], [200, 40]])) button = UIButton.alloc.initWithFrame(CGRectMake(100, 100, 200, 40)) button.setBackgroundColor UIColor.grayColor button.setTitle "press me!", forState: UIControlStateNormal self.view.addSubview(button) end end
Once saved and ran (via
rake), this code spawned the most impressive and most beautiful application of all time … Feel free to take a look at the following git repository to get in touch with more advanced examples :)
