Plugins and hooks

We leverage all the existing flake8 infrastructure and tools. There are different integrations for your workflow.


There are a lot of specific plugins that are not included, because they are, well, specific:


Hooks are 3rd-party apps and services that run flake8 on different occasions:

  • pytest-flake8 to run style checks alongside with tests

  • pre-commit to run flake8 before all commits locally

    • Note that since the default flake8 used by pre-commit does not have wemake plugin, we have to ask pre-commit to run local flake8 that is installed via wemake. A sample config for .pre-commit-config.yaml:

    -   repo: local
        -   id: flake8
            name: flake8
            description: wemake-python-styleguide enforcement
            entry: flake8
            args: ["--config=setup.cfg"]
            language: python
            types: [python]
  • pronto-flake8 to post inline-comments with violations during code-review inside your CI

  • Directly modify git pre-commit hook without third party app or service.

    • Open <your_local_repo>/.git/hooks/pre-commit.sample (git runs this script after one calls git commit. If this script exits with code 1, commit would fail)

    • Add the following code before the one checking for whitespace errors.

    # Your added code to run wemake-python-styleguide. Add this before
    # the whitespace error lines
    flake8 .
    if [ $? -ne 0 ]
     echo "Please fix the ERRORS and commit again."
     exit 1
    # If there are whitespace errors, print the offending file names and fail.
    exec git diff-index --check --cached $against --
    • Save and rename the file from pre-commit.sample to pre-commit
