Automatically reorganize messy git commit histories into clean, semantic commits

Git Smart Squash

Automatically reorganize messy git commit histories into clean, semantic commits suitable for pull request reviews.

Overview

Git Smart Squash is a command-line tool that uses AI and heuristics to intelligently group related commits and generate meaningful commit messages following conventional commit standards. It helps developers clean up their commit history before creating pull requests.

Features

• Intelligent Commit Grouping: Uses multiple strategies to group related commits:

  • File overlap analysis
  • Temporal proximity
  • Semantic similarity
  • Dependency chain detection

• AI-Powered Message Generation: Supports multiple AI providers:

  • OpenAI (GPT-4, GPT-3.5)
  • Anthropic (Claude)
  • Local models (via Ollama or llama.cpp)

• Interactive Review: Preview and adjust groupings before applying changes

• Safety First:

  • Dry-run mode by default
  • Automatic backup branch creation
  • Comprehensive safety checks

• Configurable: YAML configuration with sensible defaults

Installation

PyPI (pip)

pip install git-smart-squash

Homebrew (macOS/Linux)

brew install edverma/tools/git-smart-squash

Both installation methods are fully supported and provide the same functionality.

Requirements

• Python 3.8+
• Git 2.0+

Development Installation

git clone https://github.com/example/git-smart-squash.git
cd git-smart-squash
pip install -e .

Quick Start

# Basic usage - analyze commits between main and HEAD
git smart-squash

# Specify a different base branch
git smart-squash --base develop

# Dry run to see proposed changes
git smart-squash --dry-run

# Use cloud AI instead of default local model
git smart-squash --ai-provider openai --model gpt-4

# Skip AI and use template-based messages
git smart-squash --no-ai

Configuration

Git Smart Squash supports multiple configuration levels with the following precedence:

1. Explicit config (--config path/to/config.yml)
2. Local repository config (.git-smart-squash.yml in current directory)
3. Global user config (~/.git-smart-squash.yml or ~/.config/git-smart-squash/config.yml)
4. Default settings

Automatic Configuration

A default global configuration file is automatically created at ~/.git-smart-squash.yml when you first run the tool. This provides sensible defaults that work out of the box.

Local Configuration

Create a .git-smart-squash.yml file in your repository for project-specific settings:

# Generate a local config file
git-smart-squash config --init

Global Configuration

The global configuration is created automatically on first use. You can also create or update it manually:

# Create/update global config file
git-smart-squash config --init-global

This creates or updates ~/.git-smart-squash.yml with default settings that apply across all your repositories.

Configuration Options

grouping:
  time_window: 1800  # 30 minutes
  min_file_overlap: 1
  similarity_threshold: 0.7

commit_format:
  types: [feat, fix, docs, style, refactor, test, chore]
  scope_required: false
  max_subject_length: 50

ai:
  provider: local  # or openai, anthropic
  model: devstral
  api_key_env: OPENAI_API_KEY

output:
  dry_run_default: true
  backup_branch: true
  force_push_protection: true

AI Provider Setup

OpenAI

export OPENAI_API_KEY="your-api-key"
git smart-squash --ai-provider openai --model gpt-4

Anthropic

export ANTHROPIC_API_KEY="your-api-key"
git smart-squash --ai-provider anthropic --model claude-3-sonnet-20240229

Local Models (Ollama) - Default

# Install and start Ollama
ollama serve
ollama pull devstral

# Use with git-smart-squash (default configuration)
git smart-squash

# Or specify explicitly
git smart-squash --ai-provider local --model devstral

Examples

Basic Workflow

# 1. Check repository status
git smart-squash status

# 2. Analyze and group commits (dry run)
git smart-squash --dry-run

# 3. Review the generated script
cat git-smart-squash-script.sh

# 4. Apply changes if satisfied
git smart-squash --auto

Advanced Usage

# Use specific grouping strategies
git smart-squash --strategies file_overlap temporal

# Custom time window for temporal grouping
git smart-squash --time-window 3600  # 1 hour

# Generate script without AI
git smart-squash --no-ai --dry-run --output my-rebase.sh

How It Works

1. Commit Analysis: Extracts metadata, file changes, and diffs from git history
2. Intelligent Grouping: Applies multiple strategies to find related commits:
   • File Overlap: Groups commits that modify the same files
   • Temporal: Groups commits made within a time window
   • Semantic: Groups commits with similar messages or change patterns
   • Dependency: Groups commits that build upon each other
3. Message Generation: Uses AI or templates to create conventional commit messages
4. Interactive Review: Shows proposed groupings for user approval
5. Safe Execution: Creates backups and performs safety checks before applying changes

Safety Features

• Dry run by default: Preview changes before applying
• Automatic backups: Creates backup branches before operations
• Safety checks: Verifies clean working directory, no merge conflicts, etc.
• Rollback support: Easy restoration from backup branches
