Ruby Past, Present, Future
- 1. Ruby – Past, Present, Future Adam Fine
- 2. Birth February 24, 1993 1 st release December 1995 Yukihiro Matsumoto (''Matz'')
- 3. Influences Lisp Smalltalk Perl
- 4. Lisp – everything is an expression Smalltalk – everything is an object Perl – everything should be possible Fundamentals
- 5. Characteristics Dynamic Reflective High level Multi-paradigm Feature-full (closures, continuations) Portable
- 6. Implementation Single pass C interpreter Written by a small group of volunteers Led by Yukihiro Matsumoto
- 7. Progression Gain popularity throughout Japan 1999: Ruby overtakes Python's mindshare in Japan Thriving Japanese community But no English docs Very few users outside Japan
- 8. 2000 Ruby starts spreading outside Japan Pragmatic Programmers: Dave Thomas and Andy Hunt 2001: ''Programming Ruby'' (the PickAxe) - first major documentation in English Documents Ruby 1.6
- 9. Just Yesterday Mainly used for high-level scripting and web Many interesting Web ideas and approaches: Borges, Wee, Iowa, Cerise, cgikit, mod_ruby
- 10. Ruby 1.8 Released August 4 th 2003 Language cleanup, less Perlish Implementation improvements
- 11. Rails Released July 2004 David Heinemeier Hansson chose Ruby Very small codebase A lot of functionality Attracts major attention
- 12. Today
- 13. 1.8, 1.9, 2.0 1.8: Production branch 1.9: Development, experimental branch 2.0: What 1.9 will mature into YARV
- 14. YARV Lead Developer Koichi Sasada December 31, 2006: merged into the Ruby repository Bytecode-compiled
- 15. Rubinius Modelled after the Smalltalk-80 virtual machine Transparent Highly reflective Self-hosting, self-extensible Optimizable
- 16. JRuby Platform: the JVM A working interpreter, compiler in the works Better performance than MRI (CRuby) Integrates with Java Benefits from the Java codebase
- 17. The DLR and IronRuby Platform: the CLR Optimized compilation, significant performance gains But currently vaporware Doubts about extent of dynamic feature support
- 18. XRuby Platform: the JVM Compiles to JVM bytecode Performance currently better than the JRuby interpreter Integration with the Java codebase Rails by the end of the year?
- 19. The Future The Rails benchmark Ruby 2.0: re-design vs. backward compatibility New implementations, new ideas, new applications
