@simensol We are moving linting and other tooling to their own extensions. eventually, python extension will rely on the linting extensions to provide the linting feature. A main reason for this move is maintenance, and enabling the community to contribute features to the tools they love. A problem we have with the current design is that the linting feature is entirely written in TypeScript and the integration is a bit too convoluted for the community to add new features or make changes. In the new extension, there is minimal TS code and the entire linting feature is implemented using python. It should also make it easier to test and add new features to the pylint extension. You can see the code here: https://github.com/microsoft/vscode-pylint

[simensol]

Why do we need the pylint extension @karthiknadig when we already can use pylint using the following settings in VSC’s settings.json?

{
    "python.linting.pylintEnabled": true,
    "python.linting.pylintPath": "/usr/local/bin/pylint"
}
