checking OS?

[Matt Williams]

Could someone on OSX do the following for me?

1. load irb
2. execute the following:
require 'rconfig'
p Config::CONFIG["target_os"]

Thanks

If you're curious, I'm porting xrefresh-server to linux (it's on OSX
right now) -- it is for a "windows-only" firefox plugin which will
update a tab containing a website/url when a file which is a dependency
for that url is changed/added/updated.

Thanks again,
Matt

I didn't see it in the gems list.

I think you meant 'rbconfig' instead of 'rconfig':

/Users/ryanbriones ~ irb

>> require 'rbconfig'

=> false

>> Config::CONFIG['target_os']

=> "darwin9.0"

That might not give you all the info you need. For example, the ruby
