Previously, parameter docstring rendering was done in the DSLParser class. Instead, let the Parameter class render themselves.

This may be a good case for -> str | None

OTOH, I'm not sure it matters that much.

This looks good, but I think we should go further. format_docstring() itself also looks like it should probably be a method on Function objects rather than a method on the DSLParser. It doesn't reference any state on the DSLParser, except for attributes on self.function. (This has implications for python#107623!)
So, instead of self.function.docstring = self.format_docstring() in the DSLParser.do_post_block_processing_cleanup() method, it would just be self.function.format_docstring() -- the Function object would know how to format its own docstring, instead of the DSLParser object reaching in and modifying the state of the Function object.
Yes, that was my plan. I figured applying this change to Parameter was a nice start, since it makes for a small proof-of-concept PR.
I'm not sure yet how to refactor the generation phase. I have a proof-of-concept branch locally (I might have pushed it here, I don't remember, and I don't intend to find out before finishing writing this :) ) where I ended up with something like this in template_dict['docstring'] = f.render_docstring() |
