Does ruby provide a global or a method call to determine the endianess
of the underlying platform?
This is what I cooked up, but I'm wondering if there is a ruby way of
doing this.
BIG_ENDIAN = [0xFF00].pack('S') == [0xFF00].pack('n')
Blessings,
TwP
you could at least have more fun
little_endian = [42].pack('i')[0] == 42

Beware, some versions of ruby shipped with OS X have a broken pack where the endianness is swapped.

Very tricksie of you! I'm always amazed at how your mind operates.

Kinky. Is it a bug, or a hack intended to make PowerPCs look like Intel
chips?

Bug. It was fixed in a later OS update, IIRC.

Yes. Apple cross-compiled ruby from Intel to PPC and Ruby assumes the source and target architectures have the same endianness.

Sounds like a bug in Ruby's build to me...
