exclude is COMPLETELY broken

Bug Report

Given that my source code is in directory src, and I want to ignore files in src/app/models I should be able to exclude that directory or files.
The docs:
https://mypy.readthedocs.io/en/stable/command_line.html?highlight=exclude#cmdoption-mypy-exclude
give directions that simply do not work.

To Reproduce

1. call mypy --exclude /src/app/models/ src

Expected Behavior

I should see no files in src/app/models in the output of warnings/errors from mypy

Actual Behavior

I see LOTS Of files in src/app/models in the output of warnings/errors from mypy

Your Environment

• Mypy version used: 0.910
• Mypy configuration options from mypy.ini:

# Global section
[mypy]
python_version = 3.8

• Python version used: 3.8.7
• Operating system and version: Max OS 11.6

Attempted work arounds
I have similarly tried all sorts of attempts at the regex, with no success.
mypy --exclude /src/app/models/.*$ src
mypy --exclude /src/app/models$ src
exclude = 'src/app/models/$' (in the ini file)
Nothing works.
Don't you unit tests or integration tests for this stuff??

As documented, the behavior of --exclude is:

A regular expression that matches file names, directory names and paths which mypy should ignore while recursively discovering files to check.

I think --exclude doesn't apply to modules that are checked due to imports from other files: https://mypy.readthedocs.io/en/stable/running_mypy.html#follow-imports (though if true, this should be added to the documentation)

If you want to ignore errors from modules that are part of your project, you would be better off specifying this in mypy.ini like this, assuming your import path is app.models

[mypy-app.models.*]
ignore_errors = True

You might also get away with --follow-imports=silent

PS: Check your tone. If you expect people to help you, you should treat them with respect first.

Documentation was updated a while ago in #10845 , mypy just hasn't had a release yet. In any case, closing as a duplicate of #8584 (comment) or #10820

[chris1248]

As you quoted the docs above which mypy should ignore while recursively discovering files this should work. Because src/app/models is under src. A recursive search of files under src will indeed go through src/app/models.

So the original issue is still valid, and this should not be closed...
