I wrote a blog post about Generating Rasa Forms with the MetaForm accompanying the repository with the code. If you are interested in creating Forms from a single file I encourage you to check it out!
Thank you for releasing great codes !
I am developing something similar to you, and I was thinking about the related things… syntax and language, generating and loading form class…
I’ve taken a quick look just now, but I could see a lot of ideas.
Thanks for sharing, looks very interesting
