Can't exclude specified file from auto formatting when using autopep8

[Iftakharpy]

Can anyone help me to ignore the "settings.py" file in a Django project to be formatted on save? I have tried for 2 hours but couldn't get it to work. I am using Windows 10.

My vscode configurations:

{
  "editor.formatOnSave": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "[python]": {
    "editor.defaultFormatter": "ms-python.python",
    "editor.tabSize": 4,
    "editor.insertSpaces": true,
    "editor.formatOnSave": true
  },
  "python.formatting.autopep8Args": ["--exclude=settings.py"]
}

I also tried:
- "python.formatting.autopep8Args": ["--exclude settings.py"]
- "python.formatting.autopep8Args": ["--exclude */settings.py"]
- "python.formatting.autopep8Args": ["--exclude", "settings.py"]
- "python.formatting.autopep8Args": ["--exclude", "*/settings.py"]

There isn't a VS Code-specific way to ignore a single file for formatting while you have formatOnSave turned on, so it will require some trickery with your formatter directly as you seem to be trying.

BTW any of the attempts which have spaces in the string will not work as those will get passed as a single argument to autopep8, e.g. ["--exclude settings.py"] looks like all one thing and not two things.

Have you looked at the Output Panel for the extension to see if there are any error messages? Or have you tried the command manually at the command-line to make sure it works there to begin with?

I have tried the command manually and there is no error either in the output of the VS Code Python extension terminal.

I tried the following commands manually and all of them works as expected:
- autopep8 --exclude *settings.py [project-folder]\settings.py
- autopep8 --exclude *\settings.py [project-folder]\settings.py
- autopep8 --exclude **\settings.py [project-folder]\settings.py
- autopep8 --exclude [absolute-path-to-settings.py] [project-folder]\settings.py

Then tried the following settings in VS Code and none of them worked:
- "python.formatting.autopep8Args": ["--exclude", "*settings.py"] executed command > ~\.virtualenvs\HiteshRD-kLOjhAqw\Scripts\python.exe -m autopep8 --exclude *settings.py --diff i:\Projects\Practice\HiteshRD\ecom\ecom\settings.py.5f3627526e20d56bfcd37aaeaf017f2c.tmp cwd: i:\Projects\Practice\HiteshRD
- "python.formatting.autopep8Args": ["--exclude", "*\\settings.py"] executed command > ~\.virtualenvs\HiteshRD-kLOjhAqw\Scripts\python.exe -m autopep8 --exclude *\settings.py --diff i:\Projects\Practice\HiteshRD\ecom\ecom\settings.py.5f3627526e20d56bfcd37aaeaf017f2c.tmp cwd: i:\Projects\Practice\HiteshRD
- "python.formatting.autopep8Args": ["--exclude", "**\\settings.py"] executed command > ~\.virtualenvs\HiteshRD-kLOjhAqw\Scripts\python.exe -m autopep8 --exclude **\settings.py --diff i:\Projects\Practice\HiteshRD\ecom\ecom\settings.py.5f3627526e20d56bfcd37aaeaf017f2c.tmp cwd: i:\Projects\Practice\HiteshRD
- "python.formatting.autopep8Args": ["--exclude", "I:\\Projects\\Practice\\HiteshRD\\ecom\\ecom\\settings.py"] executed command > ~\.virtualenvs\HiteshRD-kLOjhAqw\Scripts\python.exe -m autopep8 --exclude I:\Projects\Practice\HiteshRD\ecom\ecom\settings.py --diff i:\Projects\Practice\HiteshRD\ecom\ecom\settings.py.5f3627526e20d56bfcd37aaeaf017f2c.tmp cwd: i:\Projects\Practice\HiteshRD

Do things work if you copy and paste those commands in the terminal from the appropriate cwd?

[Iftakharpy]

Commands ignore the settings.py file when I manually try the commands.

But when I try the command that VS Code runs in the python extension it throws the temp file doesn't exist.
