How to set styler config?

Below is my user config for formatter.

{    
    // Code Formatter Preferences
    // Preferences for this plugin
    "preferences": {
        "default_formatter": {
            "python": ["isort", "yapf"],
            "r": "formatR"
        }
    },
    
    // YAPF
    "yapf":{
        "style_config": "facebook"
    }
}

I down’t want to place each dictionary entry onto its own line. So I looked into Github and find this command:

# Place each dictionary entry onto its own line.
#each_dict_entry_on_separate_line = False

However, it occurred an error when setting to jupyterlab user preference. So I looked into Doc. It says I can browse (http://localhost:8888/jupyterlab_code_formatter/formatters) to find out what formatters are available. But I get a 422 error code when browse it.

So how can I setting each_dict_entry_on_separate_line = False? Hope to hear from you ASAP, thanks a lot!

Oh I mean download thisyapf config file from https://gist.github.com/krnd/3b8c5834c5c5c5097638ec10729787f7#file-style-yapf since you seemed to want to use that.

Anyway, since it’s working for you right now, I am closing this issue 👍

[alston19]

Actually, style_config can be a path to a yapf config file, so it is available after all. Download that yapf config you want to use and point style_config to it.

Thank you so much. It’s so kind of you. 😃 I followed your suggestion but I don’t know how to retrieve a yapf config file. So I directly changed C:\ProgramData\Anaconda3\lib\site-packages\yapf\yapflib\style.py and now it works well. Thank you again and please accept my apology for replying so late.
