I have an RSpec script that tests a program in a different language I am developing. Since I can run and test 32 and 64-bit versions of this application, I would like to have a way to signal this on the command-line.

What I really want is to do something like this:

rspec -c myspec.rb lin32

or

rspec -c myspec.rb lin64

and have the lin32 or lin64 be passed as a string I can access in the ruby file itself. Is this possible? This site mentions environment variables but that is cumbersome. It also mentioned doing ARGV manipulation -- is this a possible way of doing it?

From David Chelimsky

You can't pass arbitrary arguments to the rspec command, but you can set an environment variable like this: 

SLEEP=10 rspec test.rb

Then within the script, the value of ENV["SLEEP"] is "10", so you can say: 

sleep(ENV["SLEEP"].to_f)

Try the -- parameter. It's used to tell an app to stop processing parameters and pass the remaining ones to a child process. I don't know if rspec understands it but it's worth a try.

`rspec -c myspec.rb -- lin32`
`rspec -c myspec.rb -- lin64`
