Standardrb with lefthook

.lefthook.yml

# .lefthook.yml

# 1) Define a “common” map of commands
.common: &common_commands
  check_clean:
    run: |
      if [ -n "$(git status --porcelain)" ]; then
        echo "❌ Uncommitted changes detected. Please commit or stash before pushing."
        exit 1
      fi
  standard_fix:
    run: |
      echo "Running standardrb --fix..."
      bundle exec standardrb --fix

      if [ -n "$(git status --porcelain)" ]; then
        echo "🔧 Auto-fixes detected. Committing..."
        git add -u
        git commit -m 'Auto-format: standardrb --fix'
        exit 1
      else
        echo "✅ No style changes to commit."
      fi

# 2) Reuse it in as many hooks as you need:
pre-push:
  commands:
    <<: *common_commands

post-merge:
  commands:
    <<: *common_commands

post-commit:
  commands:
    <<: *common_commands

Usage

Add gems:

bundle add lefthook
bundle add standard
bundle add standard-rails

Setup standard-rails (optional, often requires a lot of changes):

Add the provided .standard.yml file.

Install Left Hook:

lefthook install

Copy/paste the .lefthook.yml file.

Install again to update the hooks

lefthook install

Commits, pushes and merges should now check if clean, it'll also run standardrb --fix before

Commit to verify things are working:

git add -A && git commit -m "Have some standards! Add lefthook and standard"
