Git Flow Finish Branch

Complete current Git Flow branch: $ARGUMENTS

Current Repository State

• Current branch: !git branch --show-current
• Branch type: !git branch --show-current | grep -oE '^(feature|release|hotfix)' || echo "Not a Git Flow branch"
• Git status: !git status --porcelain
• Unpushed commits: !git log @{u}.. --oneline 2>/dev/null | wc -l | tr -d ' '
• Latest tag: !git describe --tags --abbrev=0 2>/dev/null || echo "No tags"
• Test status: !npm test 2>/dev/null | tail -20 || echo "No test command available"

Task

Complete the current Git Flow branch by merging it to appropriate target branch(es):

1. Branch Type Detection

Detect the current branch type and determine merge strategy:

CURRENT_BRANCH=$(git branch --show-current)

if [[ $CURRENT_BRANCH == feature/* ]]; then
  BRANCH_TYPE="feature"
  MERGE_TO="develop"
  CREATE_TAG="no"
elif [[ $CURRENT_BRANCH == release/* ]]; then
  BRANCH_TYPE="release"
  MERGE_TO="main develop"
  CREATE_TAG="yes"
  TAG_NAME="${CURRENT_BRANCH#release/}"
elif [[ $CURRENT_BRANCH == hotfix/* ]]; then
  BRANCH_TYPE="hotfix"
  MERGE_TO="main develop"
  CREATE_TAG="yes"
  # Increment patch version from current tag
  CURRENT_TAG=$(git describe --tags --abbrev=0 origin/main 2>/dev/null)
  TAG_NAME="${CURRENT_TAG%.*}.$((${CURRENT_TAG##*.} + 1))"
else
  echo "❌ Not on a Git Flow branch (feature/release/hotfix)"
  exit 1
fi

2. Pre-Merge Validation

Before merging, validate these conditions:

Critical Checks:

• ✅ All changes are committed (no uncommitted files)
• ✅ All commits are pushed to remote
• ✅ Tests are passing (run test suite)
• ✅ No merge conflicts with target branch
• ✅ Branch is up to date with remote

🔍 Pre-Merge Validation

✓ Working directory clean
✓ All commits pushed to remote
✓ Running tests...
  ├─ Unit tests: 45/45 passed
  ├─ Integration tests: 12/12 passed
  └─ All tests passed ✓

✓ Checking for merge conflicts with develop...
  └─ No conflicts detected ✓

✓ Branch is up to date with remote ✓

Ready to merge!

3. Feature Branch Finish

For feature/ branches:

# Ensure all commits are pushed
git push

# Switch to develop
git checkout develop

# Pull latest changes
git pull origin develop

# Merge feature branch (no fast-forward)
git merge --no-ff feature/$NAME -m "Merge feature/$NAME into develop

$(git log develop..feature/$NAME --oneline)
