Matz's Ruby Interpreter or Ruby MRI (also called CRuby) is the reference implementation of the Ruby programming language named after Ruby creator Yukihiro Matsumoto ("Matz"). Until the specification of the Ruby language in 2011, the MRI implementation was considered the ''de facto'' reference, especially since an independent attempt to create the specification (RubySpec) has failed.〔 The latest stable version is Ruby 2.2.3.〔 ==History== Yukihiro Matsumoto ("Matz") 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. The 1.8 branch has been maintained until June 2013, and 1.8.7 releases have been released since April 2008.〔(【引用サイトリンク】 title = 1.8.7 NEWS )〕 This version provides bug fixes, but also many Ruby feature enhancements. The RubySpec project has independently created a large test suite that captures 1.8.6/1.8.7/1.9 behavior as a reference conformance tool. Ruby MRI 1.9.2 passed over 99% of RubySpec., MRI Ruby 2.2 crashed on one of the tests. As a result of the limited uptake by the MRI developers, RubySpec project has been discontinued as of end of 2014. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ruby MRI」の詳細全文を読む スポンサード リンク
