From: Conrad Schneiker Date: 2000-06-07T05:32:07-05:00 Subject: [ruby-talk:03147] Ruby -- A better OO Perl than Perl? Python 3000 features available now? Well, at least _some_ people regard Ruby as a better OO Perl than Perl or as a means of getting anticipated Python 3000 features now. Maybe if you knew more about Ruby, you might become one of them. Obviously for a great many people, situations, and applications, Perl or Python are clearly their best respective choices. (I still use Perl from time to time and I still sometimes recommend that people check out Python.) However I suspect there are still a great many other people who generally like Perl or Python, but who for reasons of need and temperament are not locked into them, and who also would like something that provides a more powerful and more uniform and easier to use variation on the same sorts of themes that made Perl or Python initially attractive and useful power tools. The purpose of this note is simply to let such people know about Ruby. (I discovered Ruby in a passing reference I chanced across when perusing comp.lang.python last year, and I am trying to pass on that inadvertent favor in this experiment.) 1 About Ruby. 1.1 What is Ruby? Ruby is a relatively new, very high level, fully OO language that integrated many good ideas from Perl, Python, Smalltalk, Eiffel, ADA, Clu, and Lisp. (Ruby is more fully OO than Python.) In addition to common OO features, Ruby has threads, singleton methods, mix-ins, fully integrated closures and iterators, plus proper meta-classes. Ruby is a relatively easy to learn and easy to read language, yet it is very powerful and sophisticated. Ruby has a true mark-and-sweep garbage collector, which makes code more reliable and simplifies writing extensions. For many of us, Ruby is "better Perl than Perl" and a "better Python than Python". You could characterize the Ruby philosophy as "there's a better way to do it" (TABWTDI). 1.2 Where can I find out more about Ruby? Ruby's home web site: http://www.ruby-lang.org/en (Ruby English language home page.) Follow the links to documentation, downloads, the Ruby application archive, the Ruby mail list archives, and lots of other interesting information. http://www.ruby-lang.org/en/whats.html (Ruby feature list.)
