@KnisterPeter, the lint check is failing because of complexity of a function:

However, this function is actually a very simple function

Maybe add // nolint:gocyclo above evaluateVariable. Idk if the other maintainer want to enforce a split of the function.

I don't insist that you remove the Syntax extension, do whatever you think is good to go with.

FYI However as long the checks are red, only the owner cplee can bypass them. Otherwise you need two approvals.

[ChristopherHX]

Thank you for implementing this.

BTW you can do --var-file vars.yml and use well known yml syntax to define vars.

@cplee This change is merged but only available on the master. Can we get a new release for this feature please?

Version was bumped over the weekend however the release workflow run failed.
