# 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:

```bash
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:

```bash
# 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)

# Push to remote
git push origin develop

# Delete local branch (unless --no-delete)
git branch -d feature/$NAME

git push origin --delete feature/$NAME
```

**Success Response:**
```

```

### 4. Release Branch Finish

For **release/** branches:

```bash
# Extract version from branch name
VERSION="${CURRENT_BRANCH#release/}"

# Ensure all commits are pushed
git push

# Merge to main first
git checkout main
git pull origin main
git merge --no-ff release/$VERSION -m "Merge release/$VERSION into main

### 6. Error Handling

**Not on Git Flow Branch:**
```
❌ Not on a Git Flow branch

Current branch: $CURRENT_BRANCH

/finish only works on:
- feature/* branches
- release/* branches
- hotfix/* branches

To finish this branch manually:
1. Switch to target branch
2. Merge manually: git merge $CURRENT_BRANCH
3. Push: git push
```

**Uncommitted Changes:**
```
❌ Cannot finish: Uncommitted changes detected

Modified files:
M  src/file1.js
M  src/file2.js

Please commit or stash your changes first:
1. Commit: git add . && git commit
2. Stash: git stash
3. Discard: git checkout .
```

**Unpushed Commits:**
```
⚠️  Warning: 3 unpushed commits detected

Commits not on remote:

```

**Test Failures:**
```
❌ Cannot finish: Tests are failing

Failed tests:
  ✗ UserService.test.js
    - should authenticate user (expected 200, got 401)
  ✗ PaymentController.test.js
    - should process payment (timeout)

Fix the failing tests before finishing:
1. Run tests: npm test
2. Fix failures
3. Commit fixes
4. Try /finish again

Skip tests? (NOT RECOMMENDED) [y/N]
```

**Merge Conflicts:**
```
❌ Merge conflict detected with develop

Conflicting files:
  src/config.js
  package.json

Resolution steps:
1. Fetch latest develop: git fetch origin develop
2. Try merge locally: git merge origin/develop
3. Resolve conflicts manually
4. Commit resolution
5. Try /finish again

Would you like to see conflict details? [Y/n]
```

**Missing Tag for Release:**
```
⚠️  Release branch missing version in CHANGELOG

Expected format in CHANGELOG.md:
## [v1.2.0] - 2025-10-01

Current CHANGELOG:
[show relevant section]

Please update CHANGELOG.md with release version.
Continue anyway? [y/N]
```

### 7. Arguments

**--no-delete**: Keep branch after merging
```bash
/finish --no-delete

# Merges but keeps local and remote branches
```

**--no-tag**: Skip tag creation (release/hotfix only)
```bash

# Merges but doesn't create version tag
```

### 8. Interactive Confirmation

For destructive operations, ask for confirmation:

```
