Support glob patterns when configuring mypy_path

[gustavgransbo]

Feature

Support the glob patterns * and ** in the mypy_path configuration.

Should work the same way as it does for the files configuration.

Pitch
I have a monorepo, with a bunch of python libraries located in a directory called libs.
All packages are namespace packages with the same namespace, but they are kept in their own directory inside of the libs directory:

repository_root
│
└───libs
│   └───pkg-a
│   |    └───namespace
│   |
│   └───pkg-b
│   |    └───namespace
│   |
│   └───pkg-c
│        └───namespace
│
└───mypy.ini

The mypy_path declaration in my mypy.ini looks something like this (but with dozens of packages):

mypy_path = $MYPY_CONFIG_FILE_DIR/libs/pkg-a:
    $MYPY_CONFIG_FILE_DIR/libs/pkg-b:
    $MYPY_CONFIG_FILE_DIR/libs/pkg-c:

It would be very convenient to use a glob pattern like this instead:

mypy_path = $MYPY_CONFIG_FILE_DIR/libs/*

It's more concise, and would avoid potential problems with forgetting to include a newly added package in mypy_path.

Thanks for a great tool!

I could have a go at implementing this, unless someone opposes the feature.

This would be a great feature! I am trying to figure out how to set the mypy_path with a wildcard, to avoid specifying all paths, also a monorepo.

[DavidVujic]

I don't fully understand why, but mypy seems to recognize the packages when putting a py.typed file in the top namespace (such as in pkg-a in your example).

Do you think this is a good enough workaround until the feature would be added @gustavgransbo?

EDIT:
maybe I went a little bit too fast here. The code editor is happy, but when running the mypy cli I get a new set of errors such as ...Source file found twice under different module names...
