just bumping this so it’s not forgotten.. 😉 cc @witty-crayon-22786 if you have the chance, would be great to get your feedback on this (no rush..)

Now also with support for providing default parametrization groups using

__defaults__

and optionally override them per target.

e.g.

__defaults__({python_sources: dict(**parametrize("default", resolve="py37", interpreter_constraints=["==3.7"])})

python_sources(
  resolve="py38",
  interpreter_constraints=["==3.8"],
  **parametrize("default"),
  **parametrize("py39", resolve="py39", interpreter_constraints=["==3.9"])
)

Will create two parametrized targets:

@parametrize=default

wich cancels out the values provided by

__defaults__

so resolve “py38" and

@parmetrize=py39

with the provided fields, so resolve “py39”.

while a target that doesn’t provide it’s own

"default"

group, will get the “py37" resolve from the defaults parametrization group

@witty-crayon-22786 I assume you’re happy with the UX of this.. do you want to review the implementation as well before we merge? (just so I know if I should wait for it..)

thanks 🙏
