6 years ago Hey Kevin,
When I wrote the original version of RubyTerraform I was only using the plan command as a manual dry run so didn't think to include the fact that a plan could be passed in the name of the parameter to apply. You are indeed right that passing the path to a plan as the :directory will achieve your desired result.
I may additionally add a :plan parameter so that the usage can be more specific but ultimately, they'd map to the same thing in terms of the generated command line. This would require some validation to make sure both aren't supplied but that shouldn't be too tricky.
This would additionally have the benefit of aligning well with the usage text from the terraform command:
Usage: terraform apply [options] [DIR-OR-PLAN]
Builds or changes infrastructure according to Terraform configuration
files in DIR.
...Happy to take a PR for it if you would like it sooner rather than later.
Thanks, Toby

Hey, Toby, I was trying to figure out a way to pass a plan file that was created with the 'plan' command to the 'apply' command. I didn't see an option to 'apply' for this. I started messing around with the apply.rb code to add a plan file option. Since the 'directory' option is required my changes failed, however, I realized then that I could just pass the plan file to the 'directory' option and it worked.
Is this the intended use for the 'directory' option with apply? If so, should the README be updated to reflect that? I read it as the directory of the terraform code just like with the plan command.
Thanks for the great module!
Kevin
