This is more like a DSL with Markdown embedded for the textual parts, but still cool. An actual Markdown syntax extension for forms would be interesting. [_____] for text fields?
Yeah, is anyone familiar with other DSLs for form/survey building and logic? For my work, where we produce lots of surveys and reuse parts of them/run near duplicates monthly, I've been curious to see if there's any dual code and GUI options out there to allow for survey programming to be version controlled and forked, etc.
This would be one: https://github.com/leemeichin/ask_awesomely
That's a client library for interacting with now defunct Typeform I/O, so it won't work anymore. But maybe the DSL itself could be an inspiration, or you could wrangle a fork of the library to create the forms locally.
