Mypy extension for Visual Studio Code

A Visual Studio Code extension with support for the mypy linter. The extension ships with mypy=1.5.1.

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 >= 3.8).
• 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-type-checker.args	[]	Custom arguments passed to mypy. E.g "mypy-type-checker.args" = ["--config-file=<file>"]
mypy-type-checker.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-type-checker.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-type-checker.interpreter	[]	Path to a python interpreter to use to run the linter server. When set to [], the interpreter for the workspace is obtained from ms-python.python extension. If set to some path, that path takes precedence, and the Python extension is not queried for the interpreter.
mypy-type-checker.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-type-checker.showNotifications	off	Setting to control when a notification is shown.
mypy-type-checker.reportingScope	file	(experimental) Setting to control if problems are reported for files open in the editor (file) or for the entire workspace (workspace).
mypy-type-checker.preferDaemon	true	(experimental) Setting to control how to invoke mypy. If true, dmypy is preferred over mypy; otherwise, mypy is preferred. Be aware, that the latter may slow down linting since it requires the mypy executable to be run whenever a file is saved or opened. Note that this setting will be overridden if mypy-type-checker.path is set.

Commands
