How to enable formatting

[p5a0u9l]

Unable to find from documentation how I should enable formatting which is "off" by default. It seems like there is no provision for python.formatting.enabled setting.

python.formatting.provider

Use "coc.preferences.formatOnType": true to enable format on type feature.
Use "coc.preferences.formatOnSaveFiletypes" to include filetypes you want format on save.
Use :call CocAction('format') to format currrent document.
Use

xmap <leader>f  <Plug>(coc-format-selected)
nmap <leader>f  <Plug>(coc-format-selected)

to format selected range.

Hm, this doesn't seem to be working; my coc-settings.json has:

{
...
"python.formatting.provider": "yapf",
"coc.preferences.formatOnSaveFiletypes": ["py"]
...
}

And I still have to manually call :Format for it to work.

Try "coc.preferences.formatOnSaveFiletypes": ["python"]

I am having same issue here as well, I cant seem to get formatting to work.

  "python.formatting.provider": "black",
  "python.formatting.blackPat": "/Users/lp/.local/share/virtualenvs/akamaictrl-BweOeLIM/bin/black",
  "coc.preferences.formatOnSaveFiletypes": [
    "python",
    "json"
  ],

when i run black i get this

black akamaictrl.py
error: cannot format akamaictrl.py: Cannot parse: 14:0:  def run(region, file):
Oh no! 💥 💔 💥
1 file failed to reformat.

I have indented def run on purpose

Adding the python.formatting.blackPath fixed the problem for me. It probably broke because I had set python.pythonPath to my virtualenv python, and coc was having trouble to find the path for black.

Is there a trick to getting formatting to format as you type?

Is there a trick to getting formatting to format as you type?

As far as I know even if you do this trick it will decrease significantly your typing experience. It's much better formatting on save ;D

Code formatting is useful in general. But sometimes, I just do not want to use it. For example, when I want to append the library to sys in the first line. Code formatting ( I use autopep8 ) forces the import of the library above sys.append, and I have an error.

Could I save file without autopep8 in some situations?

For example, :w for write with autopep8 and :wwp for write without autopep8

Could someone post a full config that makes it work?

Agree, it would be good to have a working example. I've been at this for a few days now on and off and can't get black to format on save. Have tried above ideas. Using nvim on Windows (for my sins). Here is my coc-settings file:

{
    "suggest.enablePreview": true,
    "python.jediEnabled": true,
    "coc.preferences.formatOnType": true,
    "coc.preferences.formatOnSaveFiletypes": ["python"],
    "python.formatting.provider": "black",
    "python.formatting.blackPath": "C:\\Users\\ccapr\\Anaconda3\\Scripts\\black.exe",
    "python.linting.enabled": true,
    "python.linting.pylintUseMinimalCheckers": false,
    "python.linting.pylintPath": "pylint",
    "python.condaPath": "conda"
}

This is super handy, for anyone on Linux like myself, this is the minimal config you need:

{                                                                                                                                                                            
  "python.formatting.provider": "black",
  "coc.preferences.formatOnType": true,
  "coc.preferences.formatOnSaveFiletypes": ["python"]
}

If you have python installed, CoC will prompt you to install black and you're done. Apologies I can't help with the Windows config.

I am having trouble with formatting with black. Here is my pertinent setup:

{
     "python.jediEnabled": false,
     "python.pythonPath": "~/opt/miniconda3/envs/INTELenv/bin/python",
     "python.pipenvPath": "~/opt/miniconda3/envs/INTELenv/bin/pip",
     "python.condaPath": "~/opt/miniconda3/bin/conda",
     "python.linting.enabled": true,
     "python.linting.pylintUseMinimalCheckers": false,
     "python.linting.pylintEnabled": true,
     "python.linting.pylintPath":"~/opt/miniconda3/envs/INTELenv/bin/pylint",
     "python.linting.flake8Args": ["--max-line-length=80"],
     "python.formatting.provider": "black",
     "python.formatting.blackArgs": ["--line-length","80"],
     "python.formatting.blackPath": "~/opt/miniconda3/envs/INTELenv/bin/black",
     "coc.preferences.formatOnSaveFiletypes": [
            "python",
            "javascript",
            "html",
            "markdown",
            "css",
            "dart"
    ],
}

When I save a file, it says "Formatted with Black" but nothing happens. I checked that black was working by using it in the terminal in my INTELenv and it worked. Though it wouldn't force 80 lines with the following command:

black --line-length=80 program.py

Could there be a plugin or other setting screwing things up?
