How to specify in the settings to run with a `-p` flag?

Error:

error: Source file found twice under different module names:

A working solution for a command line Mypy usage:

https://github.com/python/mypy/issues/8944#issuecomment-678725333

Question:

The solution works when I run Mypy from a command line. E.g.:

python -m mypy -p src -p tests

How to pass the -p flag in the “args” settings section?

args: [--no-strict-optional, --ignore-missing-imports, --package] <-- does not work:

Package name ‘src/foobar/spameggs.py’ cannot have a slash in it.

Thank you. I’ve tried your code above but still had issues: src/utils/foobar.py: error: Source file found twice under different module names: 'backend_data.src.common' and 'src.common'

I investigated further and here is my working solution:

-   repo: https://github.com/pre-commit/mirrors-mypy
    rev: v0.812
    hooks:
    -   id: mypy
        args: [
                '--namespace-packages',
                '--explicit-package-bases'
        ]

Having the same issue, using namespace packages. Per Guido’s comment here https://github.com/python/mypy/issues/8944#issuecomment-678725333 if we want to use mypy on namespace packages it ONLY works with -p companyname.package_name. But the problem is that pre-commit by default passes in a list of files to be checked, and that results in this error for me:

mypy.....................................................................Failed
- hook id: mypy
- exit code: 2

usage: mypy [-h] [-v] [-V] [more options; see below]
            [-m MODULE] [-p PACKAGE] [-c PROGRAM_TEXT] [files ...]
mypy: error: May only specify one of: module/package, files, or command.

Is there a way to use the -p option?
