Is there a way to parametrize a mypy run? I have a case where I'd like to run mypy twice against some files: like

mypy ./directory --always-true MY_EXPRESSION

and then `mypy ./directory --always-false MY_EXPRESSION`so that I can typecheck against two variations of some definitions (you can think of it a bit like an

#ifdef/else

macro in C). I see that I can define

--mypy-args

in the

pants.toml

file, but I can't use parametrize there. (Plus this would make it run against all files, instead of just some specific targets). However, in the

BUILD

files, where I can specify particular targets, and use parametrize, it looks like

python_source(s)

only give me options to skip mypy, but not to configure it with any specific args. Is there a way to achieve something like this? My last resort is to just settle for a wrapper script that calls

pants check <args>

twice, but I think that will have much worse reporting than something that was built in to a single

pants

invocation

Ah interesting. It does seem like that Pants may not natively support that yet, so a wrapper script may be all you have. Is it something you'd be interested in contributing?

I am still new to pants, but if I can see a good way to do it, I could look into it
