Each takes a different approach, with IronRuby, JRuby and MacRuby providing just-in-time compilation and MacRuby also providing ahead-of-time compilation. As of 2010, there are a number of complete or upcoming alternative implementations of Ruby, including YARV, JRuby, Rubinius, IronRuby, MacRuby, and HotRuby. The final draft of specifications is yet to be accepted as an Industrial Standard. The specifications of Ruby language are currently being developed by the Open Standards Promotion Center of the Information-Technology Promotion Agency (a Japanese government agency) for submission to the Japanese Industrial Standards Committee and then to the International Organization for Standardization. The standard 1.8.7 implementation is written in C, as a single-pass interpreted language. It also has a dynamic type system and automatic memory management it is therefore similar in varying respects to Smalltalk, Python, Perl, Lisp, Dylan, Pike, and CLU. Ruby supports multiple programming paradigms, including functional, object oriented, imperative and reflective. Ruby was first designed and developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan. It was also influenced by Eiffel and Lisp. Ruby is a dynamic, reflective, general-purpose object-oriented programming language that combines syntax inspired by Perl with Smalltalk-like features. Maximum running time of a program is 15 seconds. Graphics, network, file system and real-time input are not supported. Internet connection is required to compile and run a program. Online language reference and several program samples. Enhanced source code editor with syntax highlighting, line numbers, color themes and additional keyboard. Text input before program run and text output. Your programming language for iOS is amazing! The great programming tool on the AppStore. You have to buy compilations inside the application. The application is especially useful for learning the Ruby programming language. Programming language is a perfect tool for studying, complex mathematical calculation, entertainment and many other useful tasks. The classic Ruby programming language for iPad, iPhone and iPod touch.
