Git pre-commit hook that runs `eslint` with the `--fix` option to fix up issues where possible, and adds "fix"ed files into the commit
#!/bin/bash
cd "$(git rev-parse --show-toplevel)"
ESLINT="node_modules/.bin/eslint"
pwd
if [[ ! -x "$ESLINT" ]]; then
printf "\t\033[41mPlease install ESlint\033[0m (npm install eslint)\n"
exit 1
fi
STAGED_FILES=($(git diff --cached --name-only --diff-filter=ACM | grep ".jsx\{0,1\}$"))
echo "ESLint'ing ${#STAGED_FILES[@]} files"
if [[ "$STAGED_FILES" = "" ]]; then
exit 0
fi
$ESLINT "${STAGED_FILES[@]}" --fix
ESLINT_EXIT="$?"
# Re-add files since they may have been fixed
git add "${STAGED_FILES[@]}"
if [[ "${ESLINT_EXIT}" == 0 ]]; then
printf "\n\033[42mCOMMIT SUCCEEDED\033[0m\n"
else
printf "\n\033[41mCOMMIT FAILED:\033[0m Fix eslint errors and try again\n"
