http://www.rubydersleri.info Ruby Programming Language Mon, 24 Mar 2008 00:35:12 +0000 http://backend.userland.com/rss092 en Ruby is a dynamic, reflective, general purpose object-oriented programming language. Originating in Japan in the mid 1990s, Ruby was initially developed and designed by Yukihiro "Matz" Matsumoto and combines syntax inspired by Perl with Smalltalk-like object-oriented features. Ruby supports multiple programming paradigms (including functional, object oriented and imperative), and features a ... http://www.rubydersleri.info/ruby-programming-language.html The following code defines a class named Person. In addition to 'initialize', the usual constructor to create new objects, it has two methods: one to override the <=> comparison operator (so Array#sort can sort by age) and the other to override the to_s method (so Kernel#puts can format its output). ... http://www.rubydersleri.info/classes.html a = "\nThis is a double quoted string\n" a = %Q{\nThis is a double quoted string\n} a = <<BLOCK This is a multi-line double quoted string BLOCK a = %/\nThis is a double quoted string\n/ http://www.rubydersleri.info/strings.html Ruby code runs slower than many compiled languages (as is typical for interpreted languages) and other major scripting languages such as Python and Perl. However, in future releases (current revision: 1.9), Ruby will be bytecode compiled to be executed on YARV (Yet Another Ruby VM). Ruby's current memory footprint for ... http://www.rubydersleri.info/language-features.html Some features which differ notably from languages such as C or Perl: Names which begin with a capital letter are treated as constants, so local variables should begin with a lowercase letter. The sigils $ and @ do not indicate variable data type as in Perl, but rather function as scope resolution ... http://www.rubydersleri.info/language-comparison.html The syntax of Ruby is broadly similar to Perl and Python. Class and method definitions are signaled by keywords. In contrast to Perl, variables are not obligatorily prefixed with a sigil. When used, the sigil changes the semantics of scope of the variable. The most striking difference from C and ... http://www.rubydersleri.info/syntax.html Ruby is object oriented: every data type is an object, including classes and types which many other languages designate as primitives (such as integers, booleans, and "nil"). Every function is a method. Named values (variables) always designate references to objects, not the objects themselves. Ruby supports inheritance with dynamic dispatch, ... http://www.rubydersleri.info/semantics.html The language was created by Yukihiro Matsumoto, who started working on Ruby on February 24, 1993, and released it to the public in 1995. "Ruby" was named as a gemstone because of a joke within Matsumoto's circle of friends alluding to the name of the Perl programming language . As of ... http://www.rubydersleri.info/history.html
