config = <file_option>
default: None

Path to mypy.ini or alternative MyPy config file

entry_point​

--mypy-entry-point=<str>
PANTS_MYPY_ENTRY_POINT
pants.toml
[mypy]
entry_point = <str>
default: mypy

The main module for the tool. Usually, you will not want to change this from the default.

extra_requirements​

--mypy-extra-requirements="['<str>', '<str>', ...]"
PANTS_MYPY_EXTRA_REQUIREMENTS
pants.toml
[mypy]
extra_requirements = [
    '<str>',
    '<str>',
    ...,
]
default: []

Any additional requirement strings to use with the tool. This is useful if the tool allows you to install plugins or if you need to constrain a dependency to a certain version.

interpreter_constraints​

--mypy-interpreter-constraints="['<str>', '<str>', ...]"
PANTS_MYPY_INTERPRETER_CONSTRAINTS
pants.toml
[mypy]
interpreter_constraints = [

You must also set plugins = path.to.module in your mypy.ini, and set the [mypy].config option in your pants.toml.

To instead load third-party plugins, set the option [mypy].extra_requirements and set the plugins option in mypy.ini.
