Detect If Your Running On Windows

        It's an unfortunate necessity that you need to write different code for windows sometimes or at the very least load different libraries since there is no fork(), etc. This is how you can tell.

# Returns true if we are running on a MS windows platform, false otherwise.

def Kernel.is_windows?
  processor, platform, *rest = RUBY_PLATFORM.split("-")
  platform == 'mswin32'
end

I'd recommend that there be three tests, rather than include mingw32 and cygwin32. There are major OS differences between mingw32, cygwin32 and Windows, that could cause problems with paths, assumption of commands and features of the OS, etc. def Kernel.is_windows? !!RUBY_PLATFORM['mswin32'] end def Kernel.is_windows_ming? !!RUBY_PLATFORM['mingw'] end def Kernel.is_windows_cygwin? !!RUBY_PLATFORM['cygwin'] end More specific tests could look for 32-bit mode in the platforms, thought the bit-ness of the architecture shouldn't make as much of a difference as the OS being sensed.

In windows vista or windows 7 you should ask for minigw32. def Kernel.is_windows? processor, platform, *rest = RUBY_PLATFORM.split("-") platform == 'mingw32' end if Kernel.is_windows? == true puts "Windows" else puts "Unknown" end
