   A journey to find better editors for Ruby

5. 5.

   @kattrali Why I like Redcar • It is written in

   Ruby • It is an editor for Ruby • Open source • Easily extensible • Lightweight • It was open source TextMate before TextMate was open source
6. 6.

   @kattrali Features • Source control integration • Support for TextMate

   bundles • Fast project navigation between files and methods • Ability to run shell commands and process the output • Syntax checking
7. 7.

   @kattrali So many features! • Two-way communication between javascript and

   ruby in embedded web views • Evaluates Ruby code in a REPL and change the editor itself in real time • Easy to test new feature ideas • Excellent RubyMotion support! ΁(◕. ◕ ΁ʣ
8. 8.

   @kattrali Under the Hood • Runs on JRuby • Uses

   Standard Widget Toolkit for GUI bindings • Adds functionality by composition • Everything is a plugin
