Setting variables in Colang scripts about nemo-guardrails

[drazvan]

Hi @jamescalam! Thanks for reporting this. It is indeed a bug. I've already tested a fix and will be pushed to the main branch in the next day or so.

Meanwhile, you can try an alternative method, which will work even better (although at the cost of an extra LLM call):

define flow give name
    user give name
    # Extract the user's name
    $name = ...
    bot name greeting

It uses the mechanism for extracting user provided values: https://github.com/NVIDIA/NeMo-Guardrails/blob/main/docs/user_guide/advanced/extract-user-provided-values.md.

The advantage of this approach is that if the user responds with "My name is John", in this approach the name will be extracted correctly, whereas in your initial code the name would have been the full sentence.

I'll close this once the fix is pushed.

Thanks again!

For the record, this is now fixed (1ace2a7).
