Detect if required or executed?

Ruby
1

Hi all,

Is anyone aware of a way to detect if a file has been required from
another ruby process, or is being executed from the commandline? I’ve
been doing this hack:

do_executable_behavior unless ENV[‘DONT_RUN’]

but that’s clearly not ideal. I though maybe I could add something to
the bangline? But that wouldn’t help if someone runs the script
indirectly with “ruby script.rb”. Something like Module.included would
be great if there was a “required” method, I could just set a DONT_RUN
variable there.

Thanks,
Ian

There was a good discussion recently about making sure only one instance
of a script is running, maybe that helps:

Oops, I think Ara answered the right question…
