Support adding exceptions through argument | --add-exceptions

Compatibility section in docs states:

FlakeHeaven supports all flake8 plugins, formatters, and configs. However, FlakeHeaven has it’s own beautiful way to configure enabled plugins and codes. So, options like --ignore and --select unsupported.

Problem

I use flakeheaven as a linter in VSCode and some errors overlap with pylance or mypy, resulting in repeated errors and requiring more attention than it should. So ignoring overlapping errors makes sense.

However, I still want to see them when I execute flakeheaven manually, since I’m not using pyright manually.

Suggestion

It would be great to have option like --add-exceptions, which then could be used like this:

    "python.linting.flake8Path": "${workspaceFolder}/.venv/bin/flake8heavened",
    "python.linting.flake8Args": ["--add-exceptions=-F821,-F401"],

What do you think?

I can make a PR implementing it, but want to listen to your opinions/suggestions on that first.

Hi @Bobronium

did you try something like this:

    "python.linting.flake8Args": ["--config", ".vscode/flakeheaven.toml"],

#.vscode/flakeheaven.toml
[tool.flakeheaven]
base = "pyproject.toml"

[tool.flakeheaven.plugins]
pyflakes = ["+*", "-F821", "-F401"]

If so, did you encounter any issues with this approach?

EDIT:

I tried it (mian branch) with flakeheaven lint --config .vscode/flakeheaven.toml example.py and flake8heavened --config .vscode/flakeheaven.toml example.py. Both work

I’ve patched sources myself to fix --config argument and can confirm that it works, thank you.

Waiting for #80 to be resolved then.

I’ll leave issue opened for a while, since --add-exceptions still would be nice to have.
