A pre-commit hook to blacked the python code before verfying it with flake8 , this hook only blacken and verify those files which have extension "py" i.e. [*.py] and have been added to stage for committing. Unstaged files and other files are not considered. This hook also abort commit if flake8 throws any message.

.git ~ hooks ~ pre-commit

#!/bin/sh

# blacken the staged files
for file in $(git diff --cached --name-only | grep -E '\.(py)$')
do
  black "$file"
  $(git add "$file")
done

for file in $(git diff --cached --name-only | grep -E '\.(py)$')
do
  flake8 "$file"
  if [ $? -ne 0 ]; then
    echo "flake8 failed on staged file '$file'. Please check your code and try again. To check output manually run flake8 $file"
    exit 1 # exit with failure status
  fi
done
