Ruby script to detect OS

[scott216]

I don't know much about ruby scripts, but I'm trying to do something I hope is simple. I use SU on several computers (Mac & Win7) and I just set up folder syncing for my plugins folder so they would all have the same plugins. I'm using a 3DConnexion 'mouse' and it loads drivers differently on Mac vs Win 7. I'd like a ruby script that can detect which OS I'm on, then load the appropriate drivers for 3DConnexion.

For example:

If Windows
  require 'sketchup.rb'
  require '3DxSketchUp/3DxSketchUp.dll'
  file_loaded("3DxSketchUp.rb") 
else
  require 'sketchup.rb'
  require '3DxSketchUp.bundle.plugin/Contents/MacOS/3DxSketchUp.bundle'
  file_loaded("3DxSketchUp.rb")
endif

(RUBY_PLATFORM.downcase =~ /darwin/) == nilreturn true if it's run on a PC, else it's on a MAC...

Thanks! Is the write way to do the if statement

If RUBY_PLATFORM.downcase =~ /darwin/) == nil
  # Windows
  require 'sketchup.rb'
  require '3DxSketchUp/3DxSketchUp.dll'
  file_loaded("3DxSketchUp.rb")
else
  # Not Windows
  require 'sketchup.rb'
  require '3DxSketchUp.bundle.plugin/Contents/MacOS/3DxSketchUp.bundle'
  file_loaded("3DxSketchUp.rb")
end

That should do it...
BUT add the missing (
**%(#FF0000)[(]**RUBY_PLATFORM.downcase =~ /darwin/)
You can also separate the require "sketchup.rb" out of the test...

That (edit: scott's) is already almost ruby code. This should do it:

module TDxSkp

WIN = ( (Object;;RUBY_PLATFORM =~ /mswin/i || Object;;RUBY_PLATFORM =~ /mingw/i) unless defined?(WIN)
OSX = ( Object;;RUBY_PLATFORM =~ /(darwin)/i ? true ; false ) unless defined?(OSX)
if WIN
  require 'sketchup.rb'
  require '3DxSketchUp/3DxSketchUp.dll'
  file_loaded("3DxSketchUp.rb")
elsif OSX
  require 'sketchup.rb'
  require '3DxSketchUp.bundle.plugin/Contents/MacOS/3DxSketchUp.bundle'
  file_loaded("3DxSketchUp.rb")
end

end # module

We use proper operating system names because we are not detecting hardware. I'm not sure if that's the namespace ( TDxSkp) that they use, but our constants should better not float in top level namespace.

However note that 3DConnexion is a binary plugin and adds content to the Ruby environment that we can not check for errors (or we can find but not fix them).
