๐ŸŒฟ How Stacked Diffs Work: Branch Management

Key Insight: Each Commit = Its Own Branch + PR

Cascade CLI automatically creates individual branches for each commit in your stack:

# You work normally (on main or a feature branch)
git checkout main  # or: git checkout -b my-feature-branch
cc stacks create feature-auth --base main

# Make commits as usual
git commit -m "Add user authentication endpoints"
git commit -m "Add password validation logic"  
git commit -m "Add comprehensive auth tests"

# Push to stack - Cascade CLI creates separate branches automatically:
cc stacks push  # โ†’ Creates: add-user-authentication-endpoints
cc stacks push  # โ†’ Creates: add-password-validation-logic  
cc stacks push  # โ†’ Creates: add-comprehensive-auth-tests

# Submit creates individual PRs to main:
cc stacks submit  # PR #101: add-user-authentication-endpoints โ†’ main
cc stacks submit  # PR #102: add-password-validation-logic โ†’ main (depends on #101)
cc stacks submit  # PR #103: add-comprehensive-auth-tests โ†’ main (depends on #102)

Two Workflow Options:

Option 1: Work on Main (Recommended for Solo Development)

git checkout main
cc stacks create feature-name --base main
# Make commits directly on main (they stay local until you push to remote)
# Cascade CLI handles all branch creation and PR management

Option 2: Work on Feature Branch (Team-Friendly)

git checkout -b feature-work
cc stacks create feature-name --base main
# Make commits on your feature branch
# Cascade CLI creates individual branches from your feature branch
# All PRs target main, not your feature branch

What You See vs. What Reviewers See:

You (Developer) Reviewers (Bitbucket)
Work on 1 branch See 3 separate PRs
3 commits in sequence Each PR focuses on 1 logical change
git log shows: Aโ†’Bโ†’C PR #101: A, PR #102: B, PR #103: C

The Magic: Auto-Generated Branch Names

Cascade CLI creates meaningful branch names from your commit messages:

"Add user authentication endpoints"   โ†’ add-user-authentication-endpoints
"Fix login timeout bug"              โ†’ fix-login-timeout-bug  
"Refactor password validation!!!"    โ†’ refactor-password-validation

๐ŸŒŸ Why Stacked Diffs?

Traditional Git workflows often result in:

  • Large, hard-to-review PRs
  • Blocked development waiting for reviews
  • Merge conflicts from long-lived branches
  • Lost context in massive changesets

Stacked diffs solve this by:

  • โœ… Small, focused PRs that are easy to review
  • โœ… Parallel development with dependency management
  • โœ… Reduced conflicts through frequent integration
  • โœ… Better code quality via incremental feedback

From Source:

git clone https://github.com/JAManfredi/cascade-cli.git
cd cascade-cli
cargo build --release
cargo install --path .

See Installation Guide for detailed platform-specific instructions.

2. Initialize Your Repository

# Navigate to your Git repository
cd my-project

# Quick setup wizard (recommended)
cc setup

# Or manual initialization
cc init --bitbucket-url https://bitbucket.company.com

3. Create Your First Stack

# Create a new stack
cc stacks create feature-auth --base develop --description "User authentication system"

# Make multiple incremental commits (for your own tracking)
git add . && git commit -m "WIP: start authentication"
git add . && git commit -m "WIP: add login logic"
git add . && git commit -m "WIP: fix validation bugs"
git add . && git commit -m "Final: complete auth with tests"

# SQUASH + PUSH - Combine incremental commits into clean commit!
cc stacks push --squash 4  # Squashes last 4 commits into 1

# OR: Make some commits normally, then squash later ones
git commit -m "Add core authentication logic"
cc stacks push  # Push first clean commit

git commit -m "WIP: start tests"
git commit -m "WIP: more tests"  
git commit -m "Final: comprehensive test suite"

# SQUASH UNPUSHED - Only squash the last 3 commits
cc stacks push --squash 3  # Squashes and pushes as second stack entry

# BATCH SUBMIT - Submit all unsubmitted entries as separate PRs!
cc stacks submit

# Alternative options (for granular control):
cc stacks push                               # Push all unpushed commits separately
cc stacks push --since HEAD~3                # Push commits since reference
cc stacks push --commits hash1,hash2,hash3   # Push specific commits
cc stacks push --squash 4                    # Squash last 4 commits into 1 clean commit
cc stacks push --squash-since HEAD~5         # Squash all commits since reference
cc stacks submit                             # Submit all unsubmitted entries
cc stacks submit --range 1-3                 # Submit entries 1 through 3
cc stacks submit --range 2,4,6               # Submit specific entries

๐Ÿ”ง Git Hooks (Recommended)

Cascade CLI provides Git hooks that automate common stacked diff workflows:

Hook Name Purpose When It Runs
post-commit Auto-add commits to active stack with unique branch names After every git commit
pre-push Prevent force pushes, validate stack state Before git push
commit-msg Validate commit message format During git commit
prepare-commit-msg Add stack context to commit messages Before commit message editor
# Install all hooks for automated workflow
cc hooks install

# Remove all hooks 
cc hooks uninstall

# Check installation status
cc hooks status

๐Ÿช Default hooks installed:

  • Pre-push: Prevents force pushes that break stack integrity
  • Commit-msg: Validates commit message quality
  • Prepare-commit-msg: Adds helpful stack context

๐Ÿ“š Complete Hooks Guide - Detailed explanation of each hook, troubleshooting, and advanced usage

๐Ÿ’ก Pro tip: The post-commit hook (auto-add commits to stack) is available but not installed by default to avoid conflicts with existing repo hooks.

# Install optional post-commit hook if no conflicts
cc hooks install post-commit

๐Ÿ’ก Installation Tips:

  • For full automation: Install all hooks with cc hooks install
  • For manual control: Remove post-commit hook, keep others for safety
  • For team safety: Always keep pre-push to prevent stack corruption

4. Experience the Magic

# Check your stack status
cc stack
# Stack: feature-auth (3 entries)
# Entry 1: [abc123] Add authentication endpoints โ†’ PR #101
# Entry 2: [def456] Add password validation โ†’ PR #102  
# Entry 3: [ghi789] Add comprehensive tests โ†’ PR #103

# Monitor and auto-merge approved PRs
cc autoland
# โœ… Monitoring PRs for approval + passing builds
# โœ… Will auto-merge in dependency order when ready

๐Ÿ›ก๏ธ Safe Development Flow (Recommended)

Cascade CLI protects against accidentally polluting your base branch:

# โœ… SAFE: Start on base branch, but work on feature branches
git checkout main
cc stacks create my-feature --base main

# Make your changes
git checkout -b feature/auth-system  # Create feature branch
git commit -am "Add user authentication"
git commit -am "Add password validation"

# Push to stack (automatically tracks source branch)
cc push  # Adds all unpushed commits to stack with source tracking

๐Ÿš€ Auto-Branch Creation (Even Safer)

Let Cascade CLI handle branch creation automatically:

# If you accidentally work on main...
git checkout main
# (make commits directly on main - oops!)

# Cascade CLI will protect you:
cc push --auto-branch  # Creates feature branch & moves commits safely

๐Ÿ” Scattered Commit Detection

Cascade CLI detects when you're adding commits from different Git branches to the same stack and warns you:

# This creates a "scattered commit" problem:
git checkout feature-branch-1
git commit -m "Add user auth"
git checkout feature-branch-2  
git commit -m "Add admin panel"
git checkout main

# When you push both to the same stack:
cc push

# โš ๏ธ  WARNING: Scattered Commit Detection
#    You've pushed commits from different branches:
#    - feature-branch-1 (1 commit)
#    - feature-branch-2 (1 commit)
#    
#    This makes branch cleanup confusing after merge.
#    Consider organizing commits into separate stacks instead.

๐Ÿ“ Smart PR Creation

Cascade CLI automatically generates meaningful pull request titles and descriptions:

# Create draft PRs for review:
cc submit --draft

# Each PR gets intelligent metadata:
# โ”Œโ”€ PR Title: Generated from commit messages
# โ”œโ”€ Description: Combines commit details & context  
# โ”œโ”€ Branch: Auto-created with semantic naming
# โ””โ”€ Target: Points to previous stack entry or base

# Custom titles and descriptions:
cc submit 2 --title "Add advanced user auth" --description "Implements JWT tokens with refresh capabilities"

# Default behavior (auto-generated):
cc submit  # Creates well-structured PRs

How PR Content is Generated:

  • Title: Uses your commit message or most significant change
  • Description: Includes commit details, file changes, and stack context
  • Branch Context: Shows relationship to previous entries
  • Target Branch: Automatically set to build on previous stack entry

Daily Development Flow

Cascade CLI follows a simple, powerful workflow optimized for modern development:

# 1. Create & Develop
cc stacks create feature-name --base main
git commit -m "Add core functionality"
git commit -m "Add comprehensive tests"

# 2. Push & Submit (with modern shortcuts)
cc push --squash 2    # Combine commits into reviewable unit
cc submit            # Create PR with automatic dependency tracking

# 3. Auto-Land (set and forget)
cc autoland          # Monitors and merges when approved + tests pass

# 4. Iterate (if review feedback)
git commit --amend   # Update based on feedback
cc sync              # Update all dependent PRs automatically

๐Ÿ”„ Advanced Workflows: See our comprehensive Workflows Guide for complex scenarios including:

  • Multi-commit stacks with dependencies
  • Handling review feedback on middle commits
  • Managing emergency hotfixes during feature development
  • Cross-team collaboration patterns
  • Base branch updates with smart force push
  • Modern WIP-to-clean commit workflows

๐Ÿค– Smart Conflict Resolution

Automatic Conflict Resolution

Cascade CLI automatically resolves 60-80% of common rebase conflicts using intelligent pattern recognition.

โœ… Resolved Automatically

  • Import statement conflicts - Merges and deduplicates imports
  • Dependency version conflicts - Uses latest compatible versions
  • Simple formatting conflicts - Applies consistent code style
  • Non-overlapping changes - Safely combines independent modifications

How It Works

  • Pattern Recognition: Analyzes conflict types using AST parsing
  • Safe Resolution: Only resolves conflicts with zero ambiguity
  • Manual Fallback: Escalates complex conflicts to developer review
  • Audit Trail: Logs all automatic resolutions for transparency
# Smart conflict resolution in action
cc rebase
# ๐Ÿค– Auto-resolved 3 import conflicts in src/auth.rs
# ๐Ÿค– Auto-resolved 1 dependency conflict in package.json
# โš ๏ธ  Manual resolution needed: 1 logic conflict in src/validation.rs

Supported File Types for Import Resolution

  • JavaScript/TypeScript (.js, .ts, .jsx, .tsx)
  • Python (.py)
  • Rust (.rs)
  • Swift (.swift)
  • Kotlin (.kt)
  • C# (.cs)

Benefits

  • Faster rebases - No manual intervention for simple conflicts
  • Consistent results - Deterministic conflict resolution
  • Reduced errors - Eliminates common merge mistakes
  • Learning system - Improves resolution patterns over time

Configuration

# Enable/disable smart resolution
cc config set conflicts.auto_resolve true
cc config set conflicts.file_types "js,ts,py,rs"
cc config set conflicts.backup_on_resolve true

See docs/DEVELOPMENT.md for complete development guidelines, testing strategies, and contribution workflows.


๐Ÿ—๏ธ Architecture

Cascade CLI is built with:

  • ๐Ÿฆ€ Rust - Performance, safety, and reliability
  • ๐Ÿ“š git2 - Native Git operations without subprocess overhead
  • ๐ŸŒ HTTP/REST - Direct Bitbucket API integration
  • ๐ŸŽจ TUI Libraries - Rich terminal interfaces (ratatui, crossterm)
  • โšก Async - Non-blocking operations with tokio

Design Principles

  • Smart Force Push - Preserves review history while enabling safe rebases
  • Atomic Operations - All-or-nothing state changes
  • Conflict Detection - Early detection with resolution guidance
  • Graceful Degradation - Continue working when services are unavailable
