Hi folks,

I recently got bitten by some code which uses an idiom like:

if RUBY_PLATFORM =~ /win/i
  # windows stuff here
end

which is fine until you try it on a machine (like my shiny new
PowerBook) whose platform string is:

  powerpc-darwin-8.1.0

I looked around and couldn't find a systematic solution to
getting useful information from RUBY_PLATFORM so I quickly
hacked something together which you can find described at:

Hi Dan,

Please see sys-uname.

Thanks for the pointer. I did actually look for a library by you
because someone mentioned in IRC that you'd done something along these
lines.

It seems like this provides a lot better information than I can get
from RUBY_PLATFORM but is in the form of a C extension which doesn't
suit me. It might be exactly right for some other folks though.

Regards,

Matt

If it helps soothe your mind, the Win32 version is pure Ruby. :slight_smile:

PS - I updated the description of sys-uname on the RAA, so hopefully folks will discover it a little easier in the future.

But that fact doesn't help the VMS port, since the Win32 version depends
on OLE.

I'm not clear what this means. Can it be distributed as a gem for use
on Windows ,Unix, and other platforms?

That's a good idea.
