pip install fix8Fix8 will only fix issues that flake8 finds, so your existing flake8 configuration (including which plugins you have installed) will determine what gets fixed.
fix8 wraps flake8, so takes the same arguments. The easist way to use it is
to pass the files or directories you want fixed directly to it:
fix8 project/ that.py this.pyIf you have a large project you may want to wrap it, something like this:
fix8-local() {
git diff --name-only --diff-filter=d | grep '\.py$' | sort --unique | xargs --no-run-if-empty fix8
}This can be paired with isort to do both fixes with a single command:
# Put these functions in your `.bashrc` or similar
run-py-local() {
git diff --name-only --diff-filter=d | grep '\.py$' | sort --unique | xargs --no-run-if-empty "$@"
}
fix8-local() {
run-py-local fix8 && run-py-local isort
}
# Usage is then just this, but will detect and fix any changes that might need fixing
$ fix8-local
