A simple script that runs rails linters on files in feature branch. Handy for pre-commit

fastcheck.sh

#!/bin/bash

MAIN_BRANCH="master"
RUBOCOP_CMD="docker compose exec -T app bundle exec rubocop -a"
ERB_LINT_CMD="docker compose exec -T app bundle exec erb_lint -a"
ESLINT_CMD="docker compose exec -T app eslint --fix"

CHANGED_FILES=$(git diff --name-only $MAIN_BRANCH)

process_file() {
    local FILE="$1"
    case "${FILE##*.}" in
        rb)
            echo "Running $RUBOCOP_CMD on $FILE"
            $RUBOCOP_CMD "$FILE" &
            ;;
        erb)
            echo "Running $ERB_LINT_CMD on $FILE"
            $ERB_LINT_CMD "$FILE" &
            ;;
        js)
            echo "Running $ESLINT_CMD on $FILE"
            $ESLINT_CMD "$FILE" &
            ;;
    esac
}

for FILE in $CHANGED_FILES; do
    process_file "$FILE"
done

wait

echo -e "\nFormatted files compared to branch '$MAIN_BRANCH':"
echo "---------------------------------------------"
echo "$CHANGED_FILES" | sed 's/^/ - /'
