  • You can interrupt me - just ask me.. Introduction My feelings about this stuff - be honest Are you okay with informal asking? Say ‘ty’ Content - tell listeners that if there will be a little of time I will do a quick live coding example I’ll be showing some stuff live You’ve come here because you wanted to know how to develop desktop-like applications in web environment.. And..
  • Ask listeners if they know what is it.. Objective-J (if someone know what is it/someone code anything in it..) Cappuccino Objective-C Raise my hand too!
  • Basics: Objective-J => language Cappuccino => framework
  • Developed as a part of Cappuccino framework
  • Objective-C syntax When I first saw Objective-C syntax, it made me vomit.. But now I’m falling love with Cocoa.. :D
  • Describe every line: You’re telling that you are making an implementation of class Person that inherits from basic class CPObject
  • Setters and getter Describe each block -/+ data type method data type argument
  • Again describe two part of this method - name and first parameter Messaging - smalltalk! On the last line we’re sending a message to object person
  • You’re reading method name as a normal sentence eg. Cocoa example
  • + is for class methods - static - is for object methods In this example you’re creating static method that’ll alloc a new object itself
  • Show download link on page You just download the kit, unarchive it and you can develop your fist application Describe the most important things that are included in this package
  • It’s possible on windows, but it sux!
  • Show just beginning of installation Jake - modified Rake tool - compiling cappuccino git clone cappuccino, sudo gem install jake, download starter, sh, restart terminal, jake install, export CAPP_BUILD, capp gen Test -l
  • Show generating new project, describe what it contains - files, folders, etc. If you know Xcode, you also know IB Show quick example with Interface Builder and nib2cib - button, textField, HUD window -> after button click capp gen Test -t NibApplication
  • The best source of informations about Cappucino is definitely GitHub - wiki
  • Compare CPTableView in online documentation and in cappkido app
  • Really great source of inspiration
