writePython3Bin - how to pass arguments to the linter

crux · November 8, 2024, 11:44pm

A noob here.
I’m usings writers.writePython3Bin to package a python script. I need to pass --ignore=E501 to the builder which is flake8. But how do I do it?

set flakeIgnore to [ "E508" ] in the 5th argument here, I guess:

          makePythonWriter =
            python: pythonPackages: buildPythonPackages: name:
            {
              libraries ? [ ],
              flakeIgnore ? [ ],
              doCheck ? true,
              ...
            }@args:
            let
              ignoreAttribute =
                optionalString (flakeIgnore != [ ])
                  "--ignore ${concatMapStringsSep "," escapeShellArg flakeIgnore}";
            in
            makeScriptWriter (
              (builtins.removeAttrs args [
                "libraries"
                "flakeIgnore"
                "doCheck"
              ])
              // {

There is an even easier solution I also overlooked

You can just pass doCheck = false and avoid checking with linter in the first place

It’s quite recent, added only a few month ago
