Strings not being formatted by Black

[krusion]

Describe the bug

Strings longer than my set character limit (79) don't get formatted like the rest of the code.

To Reproduce

For example, take this code:

string = "test test test test test test test test test test test test test test test test test test test test test test test test test test test test test"

Expected behavior

A string split over 2 lines.

Environment

• Black's version: v2024.2.0
• OS and Python version: Windows 10, Python 3.12.2. Running in VS code

Additional context

I saw posts about this being fixed by adding "--preview" Argument. That didn't help. However, read on multiple issues that it will be the default setting starting in 2024.

These are my settings:

"editor.defaultFormatter": "ms-python.black-formatter",
    "editor.formatOnSave": true,
    "black-formatter.args": [
        "--line-length",
        "79",
        "--preview",
    ],

    "editor.codeActionsOnSave": {
        "source.organizeImports": "explicit"
    },

Should this also work with comments or just strings?

That was the case for many preview formats, however this specific one was moved under the new --unstable flag instead. See also #4208

I see! I'm a little bit confused, so what's the argument now if I want to test if it'll help me or not? Like what should I add in my settings file?

You can add unstable = true. However, at this point we're likely to drop this feature (see the issue @RedGuy12 linked).
