Access mds_var variables from script that run during workflow.

[Christopher Bradsher]

It would be nice to be able to access the mds_var variables from with a script that runs "when running workflow." The main use case I have is to be able to validate inputs eg.

if [[ -z $mds_var1 ]]; then
  echo "No username filled in. Stopping."
  exit 1
fi

if [[ $mds_var1 != $mds_var2 ]]; then
  echo "Username filled in as ${mds_var1} and ${mds_var2} which don't match. Stopping."
  exit 1
fi

Since the environment variables aren’t set until after reboot this is not currently possible to my knowledge.

Went ahead and implemented it. The Imagr fork doesn’t appear to be up to date so I had to manually edit MainController.py inside the release copy of Imagr.app

nice! BTW, I push to the dev branch so that should always be up to date.
