python
`stubgen` plugin support (via config file)
Feature
Similar to #9193, I'd like to run stubgen with a custom plugin, and more generally, let stubgen take a config file
Pitch
stubgen is a really powerful tool (thanks devs for all the hard work!), but could become even more powerful by extending type support through custom plugins. Currently, there's no way (that I have found) to pass a configuration file (or at the very least extra_plugins to build) to stubgen, while !9203 exposed this option for stubtest.
The idea would be to implement a similar approach inside stubgen so we aren't forced to use the (much slower) interpreted version of mypy
Pushed an initial implementation, happy to take feedback on how to add a test for it. Alternatively, I'd be happy to just expose a way to pass extra_plugins to build if that's preferred given that not all options in the Mypy config file will be taken into account by stubgen
I'm afraid I've never touched stubgen, so I'm probably not the best reviewer, sorry! (I'm also not a maintainer, only a triager, so I wouldn't have the power to merge your PR either.)
The idea sounds reasonable, though!
Thanks for the feedback @AlexWaygood, apologies for tagging you then. Do you happen to know who'd be a maintainer/reviewer to get this merged eventually? Thanks!
Possibly @hauntsaninja or @sobolevn if either of them has the time — but mypy is maintained by volunteers, so I can't make any promises :)
