From the FAQ [http://www.rubycentral.com/faq/rubyfaq.html] ''([escargo] 16 Jan 2008 - This gives a file not found error.''): : “Ruby is a simple and powerful object-oriented programming language, created by Yukihiro Matsumoto (who goes by the handle "matz" in this document and on the mailing lists). <
> <
> “Like [Perl], Ruby is good at text processing. Like [Smalltalk], everything in Ruby is an object, and Ruby has blocks, [iterators], meta-classes and other good stuff. <
> <
> “You can use Ruby to write servers, experiment with prototypes, and for everyday programming tasks. As a fully-integrated object-oriented language, Ruby scales well.” [RLH] Scales well? In what way? Ruby doesn't have true threads and is known to have performance issues, a quote from a rant of a long-time Ruby user [http://www.zedshaw.com/rants/rails_is_a_ghetto.html] notes about RoR: : “The main Rails application that DHH created required restarting _400 times/day. That's a production application that can't stay up for more than 4 minutes on average.” The home page for Ruby is http://www.ruby-lang.org/ Its most articulate advocates write such descriptions as, : “... it has a couple of real killer features; in particular the way blocks and the pervasive use of the visitor pattern come together change the way one writes programs for the better.” A lot of the attention Ruby has gotten lately is due to Ruby on Rails[http://www.rubyonrails.org/]. During Oct 2007, [http://www.sitepoint.com/books/rails1/] was making "''Build Your Own Ruby on Rails Web Applications''" available in PDF format for free... This author summaries Rail's guiding principles as: * convention over configuration (assumptions for defaults rather than requiring extensive initial configuration) [http://softwareengineering.vazexqi.com/files/pattern.html] * [DRY] * [agile] development ---- There is a Ruby/Tk if you want to bring your [Tk] skills into a new world: require 'tk' root = TkRoot.new() { title "Hello, world!" } Tk.mainloop() (from [http://httpd.chello.nl/k.vangelder/ruby/learntk/]) More on Ruby/Tk (for [MacOS]!) appears in the "Ruby/Tk Primer: Creating a ''cron'' GUI Interface with Ruby/Tk" [http://www.macdevcenter.com/pub/a/mac/2004/06/25/ruby_pt1.html]. Note, however, that at least one survey [http://www.pressure.to/ruby_gui_survey/] suggests that acceptance of RubyTk is dwindling. ---- === What: '''Ruby''' Where: http://www.ruby-lang.org/ http://www.rubycentral.com/book/ext_tk.html http://poignantguide.net/ruby/ Description: Programming language for quick and easy programming. A clean, consistent language design where everything is an object, [CLU] style iterators, singleton classes/methods, and lexical closures. Makes use of [Tk] (with bindings similar in concept to [Perl/Tk]) for its GUI support. Currently at version 1.8.4 .

This link [http://www.rubycentral.com/pickaxe/ext_tk.html] is about Ruby Tk.'') This [http://www.unixreview.com/documents/s=10104/ur0611l/] review of '''Ruby Cookbook''' tries to give a sense for how Ruby feels. ---- [RS]: Like [Scheme], Ruby has arbitrary-size integers as default - another hint that Tcl should have it too... [Octet-packed integers] come to mind.. [AK]: I consider the [Octet-packed integers] more something of a file-format, and less of an in-memory format. Note aside: In [Slim Binaries] I refer to the paper about ''Universal Symbol Files''. This paper advances the notion of octet-packed integers too, albeit slightly differently than [metakit] if I read the code right. - [RS]: Well, a very simple alternative would be to just keep the string rep and let [expr] work on that if it runs into a "integer value too large to represent". [NEM] notes in Jan 2008 that Tcl 8.5 does indeed now have arbitrary-size integers. ---- Within the Ruby community work on an alternative to Rails has produced http://merbivore.com/ which is a modular [MVC] [framework]. ---- See [http://www.approximity.com/ruby/Comparison_rb_st_m_java.html] for one comparison of Ruby to [C++], [CLOS], [Dylan], [Java], [Objective C], [Perl], [PHP], [Python], [Smalltalk], ---- Ruby vs Tcl: http://journal.dedasys.com/articles/2006/03/06/ruby-vs-tcl ---- ruby-tcl apparently lets you create Tcl interpreters from within Ruby. The author, Sam Stephenson, unveiled it at RubyConf 2008 during his talk, "Tcl for Rubyists", which you can watch at [http://www.bestechvideos.com/2008/12/08/rubyconf-2008-tcl-for-rubyists] (the demo begins around 40 mins 15 secs).
