.vscode/settings.json black settings in multi root project are not used

[tiborrr]

I have a project in which I have a top level .vscode/settings.json with only some basic settings.

{
    "python.testing.unittestArgs": [
        "-v",
        "-s",
        "./tests",
        "-p",
        "*test*.py"
    ],
    "python.testing.pytestEnabled": false,
    "python.testing.unittestEnabled": true,
}

I have a folder to which I want to apply custom black settings. To do so I have created:

src/main/xml_generators/.vscode/settings.json

with the following settings:

{
    "black-formatter.args": ["--line-length", "200"],
}

This however does not work. Looking at the log. I see that setting are not applied:

2024-01-03 14:31:59.295 [info] /home/tibor/project/.venv/bin/python -m black --stdin-filename /home/tibor/project/src/main/xml_generators/de.py -
2024-01-03 14:31:59.295 [info] CWD formatter: /home/tibor/project
2024-01-03 14:31:59.426 [info] reformatted /home/tibor/project/src/main/xml_generators/de.py

All done! ✨ 🍰 ✨
1 file reformatted.

@tiborrr Are you using *.code-workspace to define the various project roots? VS code will treat each folder added in .code-workspace as a project root and only then it can use the .vscode/setting.json if you have multiple projects in the same workspace.

What I recommend is using black config like this https://black.readthedocs.io/en/stable/usage_and_configuration/the_basics.html#configuration-via-a-file , and set the black-formatter.cwd to ${fileDirname} this will allow black to automatically pick up the settings. This way it will work in your CI and in VS code the same way. If you use the other approach you will have to handle it separately in CI.

Lastly, the initial part of the Black formatter logs shows you the settings the extension sees.
