This is a plugin for the Palantir's Python Language Server (https://github.com/palantir/python-language-server)

It, like mypy, requires Python 3.2 or newer.

Install into the same virtualenv as pyls itself.

pip install pyls-mypy

live_mode (default is True) provides type checking as you type.

As mypy is unaware of what file path is being checked, there are limitations with live_mode

• Imports cannot be followed correctly
• Stub files are not validated correctly

Turning off live_mode means you must save your changes for mypy diagnostics to update correctly.

Depending on your editor, the configuration should be roughly like this:

"pyls":
{
    "plugins":
    {
        "pyls_mypy":
        {
            "enabled": true,
            "live_mode": false
        }
    }
}
