or = for a constant

[Bob Archer]

Hello,

=20

I want to set a constant to be the value from an env variable or if that
is not there set it to the current directory.

=20

So, I am doing this:

=20

WORKINGDIR =3D ENV['CCNetWorkingDirectory'] ? =
ENV['CCNetWorkingDirectory']
: "."

=20

But it doesn't seem very Ruby/DRY like.

=20

Is there a better way to do this?

Sorry for the basic question... but 5 chapters into Why's guide and I
haven't got to a solution yet.

Is there a better way to do this?

WORKINGDIR = ENV['CCNetWorkingDirectory'] || "."
