one-liner for checking platform?

[Giles Bowkett]

I want to release some code without encouraging an OS X monoculture:

...but I have some nifty but not *absolutely* essential functionality
which currently I only know how to do on OS X. Is there a dependable
"if platform?(apple)" I can use?

Actually, now that I put it that way, I'm going to write one. But does
anyone know the quickest, cleanest way?

class Kernel
def os_x?
# ???
end
end

The gems discussion recently had somebody who specified the wrong
string indicating Windows for their platform - I wasn't sure if that
was the poster's mistake or a weird overabundance of useful
platform-indicative strings in gems or Ruby, but I want to avoid that
same pitfall.

Use the constant RUBY_PLATFORM

On my platform it is
# => "i686-linux"

on windows, its different

on apple i guess too


if you dont need a one liner you can use this


def which_platform?
$RUBY_PLATFORM ||=
case RUBY_PLATFORM.downcase
when /linux|bsd|solaris|hpux|powerpc-darwin/
:unix
when /mswin32|mingw32|bccwin32/
:windows
when /cygwin/
:cygwin
when /java/
:java
else
ther
end
end

Hi Giles, my bet is

RUBY_PLATFORM.include?('darwin')

That's why include?('win') is not a good test for Windows.

Also cygwin.
