'''Crystal''' is a [[general-purpose programming language|general-purpose]], [[object-oriented programming language|object-oriented]] programming language designed and developed by Ary Borenszweig and Juan Wajnerman and over one-hundred listed contributors.<ref>[https://github.com/manastech/crystal Crystal source code]</ref> Crystal is developed as open source software (under the [[Apache License]], Version 2.0) with syntax inspired by [[Ruby (programming language)|Ruby]]. The language is statically type-checked but does not require that the type of variables or method arguments be specified. This is the result of advanced global [[type inference]].<ref>[http://crystal-lang.org/2013/09/23/type-inference-part-1.html Type inference part 1]</ref> Its first official release was in June 2014.<ref>[http://motion-express.com/blog/why-use-crystal-lang Why Crystal programming language?]</ref><ref>[http://crystal-lang.org/2014/06/19/crystal-0.1.0-released.html Crystal 0.1.0 released!]</ref> While the original Crystal compiler was written in Ruby, in 2013 a new compiler written using the Crystal programming language itself was released.<ref>[http://crystal-lang.org/2013/11/14/good-bye-ruby-thursday.html Good-bye Ruby Thursday]</ref> The language is in an active development phase.

==History==

Work on the language began in June 2011,<ref name="story"/> with the purpose of creating a language which had the elegance and productivity of Ruby and the speed, efficiency and type safety of a compiled language.<ref name="why_crystal"/><ref name="story"/> Initially called ''Joy'', it was quickly renamed to ''Crystal''.<ref name="story"/>

In November 2013, the Crystal compiler (previously written in Ruby) became self-hosting.<ref name="goodbye_ruby"/> The first official version was released in June 2014.<ref name="rel_0.1.0"/>
