#ruby_implementation ⇒ Object

I test and deploy some of the project on jruby - this makes it easier to customize my gemfiles. Works for ruby 1.8.7 & 1.9.3 & 1.9.2 on windows( 7 & xp) & linux ( debian Lenny) using rubyinstaller for windows and using mri ruby buillt from source for linux Works for jruby 1.7.0.rc1 and jruby 1.6.3 on windows (7 & xp) At this point it’s essentially just an alias fro platform & platform?, since it queries RUBY_PLATFORM, but this may change in the future In the future I may start using RUBY_ENGINE

#ruby_version ⇒ Object

In case ruby ever reaches version 19 :-) or some 2.19 :-) only matching 1.9 at the begining of the line Returns an integer for easy version comparison 200 > 187 ( Version two is newer :-) ) if ruby_version > 187 , install new version of the gem.

#windows? ⇒ Boolean

These are just aliases for convinience, I really doubt somebody would use them System Wide on an object for any other purpose.
