Mypy extension for Visual Studio Code

A Visual Studio Code extension with support for the mypy linter. The extension ships with mypy=1.1.1.

For more information on mypy, see https://www.mypy-lang.org/.

Note:

  • This extension is supported for all actively supported versions of the python language (i.e., python >= 3.7).
  • The bundled mypy is only used if there is no installed version of mypy found in the selected python environment.
  • Minimum supported version of mypy is 1.0.0.

Usage

Once installed in Visual Studio Code, mypy will be automatically executed when you open a Python file.

If you want to disable mypy, you can disable this extension per workspace in Visual Studio Code.

Settings

Settings Default Description
mypy.args [] Custom arguments passed to mypy. E.g "mypy.args" = ["--config-file=<file>"]
mypy.severity { "error": "Error", "note": "Information" } Controls mapping of severity from mypy to VS Code severity when displaying in the problems window. You can override specific mypy error codes { "error": "Error", "note": "Information", "name-defined": "Warning" }
mypy.path [] Setting to provide custom mypy executable. This will slow down linting, since we will have to run mypy executable every time or file save or open. Example 1: ["~/global_env/mypy"] Example 2: ["conda", "run", "-n", "lint_env", "python", "-m", "mypy"]
mypy.interpreter [] Path to a python interpreter to use to run the linter server.
mypy.importStrategy useBundled Setting to choose where to load mypy from. useBundled picks mypy bundled with the extension. fromEnvironment uses mypy available in the environment.
mypy.showNotification off Setting to control when a notification is shown.

Commands

Command Description
Mypy: Restart Server Force re-start the linter server.
