Cached values override local config

[D-K-E]

I use black and mypy for formatting and linting. I have tried to pass an argument to black to use 79 characters for lines by modifying my project's coc-settings.json.

After that I called CocRestart and closed and reopened the nvim. However somewhere along that process, I assume that the cached values corrupted the use of local settings, because I am constantly asked to install black, and select a linter, whereas my project coc-settings.json is the following:

{
    "python.linting.pylintEnabled": false,
    "python.linting.mypyEnabled": true,
    "python.linting.mypyPath": "/home/name/miniconda3/envs/dev-python/bin/mypy",
    "python.linting.enabled": true,
    "python.formatting.provider": "black",
    "python.formatting.blackPath": "/home/name/miniconda3/envs/dev-python/bin/black",
    "python.formatting.blackArgs": [
        "-l",
        "79"
    ]
}

Those are valid paths to the executable of black and mypy. I could not find how to clean cached values. The log clearly shows that cached values exist by the way: Here is the relative part from the output of CocOpenLog:

2019-09-20T04:03:39.658 INFO (pid:4577) [extension-coc-python] - Python Extension: Cached data exists getEnvironmentVariables, /media/name/Data7510/GitProjects/vie/viewer/glwidget.py

Looks like you have .vim/coc-settings.json in your project root.

[D-K-E]

Indeed I do. However cached values are overriding the settings I placed there.

I'm experiencing similar issue with the latest coc-python whenever i open a python file it always prompts me to select/install a linter, even though it's already set, and linter (flake8) is already installed in the current active interpreter I checked the interpreter is set correctly

[Gee19]

I also cannot switch from pylint, seems it is always enabled and running CocCommand python.setLinter to flake8 does nothing.

Project root coc-settings:

{
  "python.pythonPath": "/Users/jhaine/Envs/sdelements/bin/python",
  "python.linting.enabled": true,
  "python.linting.pylintEnabled": false,
  "python.linting.flake8Enabled": true,
  "python.linting.flake8Args": ["--ignore=E501,W601"],
  "coc.preferences.jumpCommand": "drop",
  "diagnostic.checkCurrentLine": true,
  "tsserver.npm": "/usr/local/bin/npm"
}

I seem to be running into a similar situation:

• Initially, I set {"python.formatting.provider": "yapf"} in my workspace config, but CocAction('format') would continually ask me to install autopep8.
• After setting {"python.formatting.provider": "yapf"} in the user config as well, I can now format using yapf.
• However, if I then remove the setting from the user config, yapf no longer works correctly (which seems inconsistent with the idea of cached values overriding my workspace settings).

Note: there are other settings in my workspace config that seem to be taking effect. Are the final settings resolved on an individual basis?

Question: is there a way to dump what coc thinks are the final resolved settings? If not, would it be worth making a feature request for this?

[Gee19]

Thank you @claytonlemons, after reading your comment I went back to the docs and learned of the :CocConfig and :CocLocalConfig commands.

• https://github.com/neoclide/coc.nvim/wiki/Using-the-configuration-file#configuration-file-resolve
• https://github.com/neoclide/coc.nvim/pull/1110

I recently switched to neovim and I assumed coc would still load from ~/.vim/coc-settings.json but it seems otherwise as copying it to ~/.config/nvim/coc-settings.json solved it.

But it does beg the question of why my workspace folder wasn't working 👼

[5ilvers]

Can confirm @claytonlemons 's workaround is working for me

[chemzqm]

Reproduced, "python.formatting.provider" could be wrong.

[zlesnr]

Where do I put the config that's referenced here? Running the CocCommand doesn't save anything, or seem to do anything for the litner.

[5ilvers]

@zlesnr see @Gee19 's comment

Same, or at least similar, problem here. I want to use mypy and black in a specific project, so I created this .vim/coc-settings.json file:

{
  "python.linting.pylintEnabled": false,
  "python.linting.enabled": true,
  "python.linting.mypyEnabled": true,
  "python.linting.mypyPath": "~/.cache/pypoetry/virtualenvs/usignals-py3.7/bin/mypy",
  "python.formatting.provider": "black",
  "python.formatting.blackPath": "~/.cache/pypoetry/virtualenvs/usignals-py3.7/bin/black"
}

However, I keep getting asked to install pylint as a linter.

Hey there.

I moved my global configuration file away and I've this local configuration file :

{
    "python.linting.enabled": true,
    "python.linting.pylintEnabled": false,
    "python.linting.flake8Enabled": true,
    "python.formatting.provider": "black",
    "python.formatting.blackArgs": ["-l", "120"]
}

No original story here, coc still wants me to install pylint and does not allow me to use flake8 at the moment.

[eyalk5]

There is no option to clear cache?

I'm no expert or coc-py dev, but if you're using an env you should set it. @claytonlemons and @Gee19 explanations works as a charm :D
