✨ Add support for modules with __main__.py

[Olegt0rr]

Some projects use __main__.py as the default module entry point:
https://docs.python.org/3/library/__main__.html#main-py-in-python-packages

It would be nice to support it out of the box

Thanks for the interest! Could you please start with a question discussion here? https://github.com/tiangolo/fastapi-cli/discussions/new?category=questions

That will make it easier to understand your use case better.

From my understanding, __main__.py is what is called when calling a module/package directly from the command line, e.g. python -m my_package.some_module.

That would look for a file my_package/some_module/__main__.py, and if found, would just execute/import it, and importing it would have whatever is the intended side effect of calling that module as a script.

This means that in the case of FastAPI, that module would probably have something that would be run directly when imported, instead of just having a variable app or something, that module would probably call uvicorn.run() directly or something similar.

In that case, I don't think it would make sense for FastAPI CLI to import from there...

It was actually in an early version of my local code, but I realized it didn't really make sense to me.

But if you feel there's another use case I'm not seeing, please create a new discussion with your example code and we can continue from there. 🤓

For now, I'll pass on this one. ☕
