Mac OS X 10.5, or Leopard, due in spring of 2007, will include the Web application framework Ruby on Rails (RoR). Apple mentions RoR on its Leopard Server Web page, and the RoR Web site clarifies that it will be available in the non-server version of Leopard, as well.
The Ruby coding language is considered by many to be easy to use.
The RoR blog says "Weive been working with Apple for quite a while to make this happen and its great to finally be able to share it with the world. The love for Ruby has definitely spread inside Apple and weive been thrilled to see the level of interest theyive taken to get OS X to be a premiere development and deployment platform for Rails."
The preview version of Leopard distributed to developers at WWDC includes Ruby 1.8.4 and Rails 1.1.2. The RoR group plans to have Rails 1.2.x, Mongrel, SQLite bindings, and several other Ruby features included before Mac OS X 10.5 officially ships next spring.
