📦 Installation

npm install -g alcapush

🚀 Quick Start

1. Configure your API key:

acp config set ACP_API_KEY=sk-your-openai-api-key

2. Make some changes to your code

3. Generate and commit:

acp

That's it! Alcapush will:

• Analyze your changes
• Generate a meaningful commit message
• Ask for confirmation
• Commit your changes

🎯 Usage

Basic Usage

# Generate commit for staged changes
acp

# Auto-commit without confirmation
acp --yes

# Add additional context
acp -c "Fixing bug reported in issue #123"

# Use full GitMoji specification
acp --fgm

Configuration

# Set configuration
acp config set KEY=VALUE

# Get configuration value
acp config get KEY

# List all configuration
acp config list

# Describe configuration options
acp config describe
acp config describe ACP_MODEL

# Test your configuration
acp config test

Git Hooks

# Install git hooks (prepare-commit-msg and commit-msg)
acp hook install

# Check hook status
acp hook status

# Uninstall git hooks
acp hook uninstall

Installed Hooks:

• prepare-commit-msg: Automatically generates commit messages when you run git commit without a message
• commit-msg: Validates commit messages against Conventional Commits specification

After installing hooks, you can simply run git commit and Alcapush will automatically generate and validate your commit messages!

Commit History & Favorites

# View commit history (last 50 commits)
acp history

# View commit history with custom limit
acp history 20

# Clear commit history
acp history clear

# Add a commit message to favorites
acp favorite add "feat: add user authentication"

# Remove a commit message from favorites
acp favorite remove "feat: add user authentication"

# List all favorites (sorted by usage)
acp favorite list

Features:

• 📜 Automatic History: All commits are automatically saved to history with branch information
• ⭐ Favorites: Save frequently used commit message patterns for quick reference
• 📊 Usage Tracking: Favorites are sorted by usage count to show your most-used patterns
• 🔍 Branch Context: History includes branch information for better context

Batch Commit Generation

Split large changes into multiple logical commits with AI-powered grouping:

# Split changes into 3 commits
acp batch 3

# Include unstaged changes
acp batch 3 --all

# Auto-commit without confirmation
acp batch 3 --yes

# Add context to commit messages
acp batch 3 --context "Refactoring authentication system"

How it works:

1. AI analyzes all your changed files
2. Groups related files together based on functionality, dependencies, and feature boundaries
3. Creates logical commit groups (e.g., "User authentication feature", "Update dependencies")
4. Generates commit messages for each group
5. Commits each group separately

Example:

$ acp batch 2

✔ Found 5 file(s) with changes
✔ Grouped into 2 commit(s)

📦 Will create 2 commit(s):

  1. User authentication feature (3 files)
     Adds login and registration functionality with related utilities
     Files: src/auth.ts, src/login.ts, test/auth.test.ts

  2. Update dependencies (2 files)
     Updates package.json with new dependency versions
     Files: package.json, package-lock.json

✔ Generated 2 commit message(s)

Features:

• 🤖 AI-Powered Grouping: Intelligently groups related files together
• 📝 Logical Commits: Creates meaningful, atomic commits
• 🔍 Smart Validation: Only commits files that actually have changes
• ⚡ Automatic Staging: Handles file staging/unstaging automatically
• 🎯 Context-Aware: Uses branch context to improve grouping decisions

Branch-Aware Commit Messages

Alcapush automatically detects your current branch and includes branch context in commit message generation:

# On feature/user-auth branch
git checkout -b feature/user-auth
acp
# AI will suggest: feat(user-auth): ... based on branch name

# On fix/login-bug branch
git checkout -b fix/login-bug
acp
# AI will suggest: fix(login-bug): ... based on branch name

# On hotfix/security-patch branch
git checkout -b hotfix/security-patch
acp
# AI will suggest: fix(security-patch): ... based on branch name

Supported Branch Patterns:

• feature/ or feat/ → Suggests feat type
• fix/ or bugfix/ → Suggests fix type
• hotfix/ → Suggests fix type
• chore/ → Suggests chore type
• docs/ → Suggests docs type
• refactor/ → Suggests refactor type
• test/ → Suggests test type
• perf/ → Suggests perf type
• release/ → Suggests chore type

Scope Extraction:

• Automatically extracts scope from branch names (e.g., feature/user-auth → scope: user-auth)
• Cleans up ticket numbers and other patterns (e.g., feature/JIRA-123-auth → scope: auth)
• Works with multi-level branch names (e.g., feature/api/user-auth → scope: api/user-auth)

💰 Cost Estimation

Alcapush provides real-time cost estimation before generating commit messages, helping you understand the API usage and costs upfront.

How It Works

Before generating a commit message, Alcapush displays:

• Input tokens: Estimated tokens in your diff and prompts
• Output tokens: Estimated tokens for the generated message
• Estimated cost: Calculated cost in USD based on your selected model

Example Output

$ acp

📊 Usage Estimate:
   Input tokens: 1,234
   Output tokens (estimated): 500
   Estimated cost: $0.000062

Proceed with generating commit message? › (Y/n)

Supported Models & Pricing

Alcapush includes up-to-date pricing for popular models:

| Model | Input (per 1M tokens) | Output (per 1M tokens) | |-------|---------------------|----------------------| | GPT-5-nano | $0.05 | $0.40 | | GPT-4o-mini | $0.15 | $0.60 | | GPT-4o | $2.50 | $10.00 | | Claude 3.5 Sonnet | $3.00 | $15.00 | | Gemini Pro | $0.50 | $1.50 | | Ollama (local) | Free | Free |

Pricing is automatically calculated based on current API rates (verified November 2024)

Cost Optimization Tips

• Use gpt-5-nano or gpt-4o-mini for the lowest costs
• Use Ollama for free local processing
• Adjust ACP_TOKENS_MAX_OUTPUT to limit output token usage
• Use ACP_TOKENS_MAX_INPUT to control input size for large diffs
