Support glob patterns when configuring mypy_path #9965
Description
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_pathwith a wildcard, to avoid specifying all paths, also a monorepo.DavidVujic commentedon Nov 16, 2022
I don't fully understand why, but mypy seems to recognize the packages when putting a
py.typedfile in the top namespace (such as inpkg-ain 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
mypycli I get a new set of errors such as...Source file found twice under different module names...jaklan commentedon Mar 22, 2025
4 years later,
mypystill doesn't support PEP 420-based implicit namespace packages properly, forcing us to deal withmypy_path. But as mentioned by @gustavgransbo - it's a total pain when used in a monorepo which could be easily improved withglobsupport...
