## ✨ What is SmartGit?

SmartGit is a sophisticated, promise-based Git toolkit designed for Node.js applications. Built on top of `isomorphic-git`, it provides a clean, intuitive API for repository management, diff analysis, and commit history exploration. Perfect for automation tools, CI/CD pipelines, and any application that needs to interact with Git repositories programmatically.

## 🎯 Key Features

- **🔧 Repository Management** - Create, clone, and open repositories with ease
- **🌐 Remote Operations** - Manage remotes and push changes effortlessly  
- **📊 Diff Analysis** - Get detailed diffs of uncommitted changes
- **📚 Commit History** - Extract commit messages with metadata and version tracking
- **⚡ Async/Await** - Modern promise-based API throughout
- **🛡️ TypeScript First** - Full type safety and IntelliSense support
- **🎯 Production Ready** - Battle-tested and actively maintained

## 📦 Installation

```bash
# Using pnpm (recommended)
pnpm install @push.rocks/smartgit

# Using npm
npm install @push.rocks/smartgit

# Using yarn
yarn add @push.rocks/smartgit
```

## 🚀 Quick Start

```typescript
import { Smartgit } from '@push.rocks/smartgit';

// Initialize SmartGit
const smartgit = new Smartgit();
await smartgit.init();

// Clone a repository
const repo = await smartgit.createRepoByClone(
  'https://github.com/username/repo.git',
  './local-repo'
);

console.log('🎉 Repository cloned successfully!');
```

## 📖 Usage Guide

### 🏗️ Repository Operations

#### Creating a New Repository

```typescript
const repo = await smartgit.createRepoByInit('./my-new-repo');
```

#### Cloning from Remote

```typescript
const repo = await smartgit.createRepoByClone(
  'https://github.com/octocat/Hello-World.git',
  './hello-world'
);
```

#### Opening Existing Repository

```typescript
const repo = await smartgit.createRepoByOpen('./existing-repo');
```

### 🌐 Working with Remotes

#### List All Remotes

```typescript
const remotes = await repo.listRemotes();
console.log(remotes);
// Output: [{ remote: 'origin', url: 'https://github.com/...' }]
```

#### Ensure Remote Exists

```typescript
await repo.ensureRemote('origin', 'https://github.com/username/repo.git');
```

#### Get Remote URL

```typescript
const originUrl = await repo.getUrlForRemote('origin');
console.log(`📡 Origin URL: ${originUrl}`);
```

#### Push to Remote

```typescript
await repo.pushBranchToRemote('main', 'origin');
console.log('✅ Changes pushed successfully!');
```

### 📊 Diff Analysis

Get a detailed diff of uncommitted changes (perfect for code review automation):

```typescript
const diffs = await repo.getUncommittedDiff(['node_modules/*', '*.log']);

diffs.forEach(diff => {
  console.log('📝 File changes:');
  console.log(diff);
});
```

### 📚 Commit History Analysis

Extract commit history with package.json version tracking:

```typescript
const history = await repo.getAllCommitMessages();

history.forEach(commit => {
  console.log(`🕐 ${commit.date} | v${commit.version} | ${commit.message}`);
});

// Example output:
// 🕐 2024-01-15 | v1.2.3 | feat: add new authentication method
// 🕐 2024-01-14 | v1.2.2 | fix: resolve memory leak in parser
```

## 🛠️ Advanced Usage

### Error Handling

```typescript
try {
  const repo = await smartgit.createRepoByClone(invalidUrl, './test');
} catch (error) {
  console.error('❌ Clone failed:', error.message);
}
```

### Working with Multiple Repositories

```typescript
const smartgit = new Smartgit();
await smartgit.init();

const repositories = [
  await smartgit.createRepoByOpen('./repo1'),
  await smartgit.createRepoByOpen('./repo2'),
  await smartgit.createRepoByOpen('./repo3')
];

// Analyze all repositories
for (const repo of repositories) {
  const remotes = await repo.listRemotes();
  console.log(`📂 Repository has ${remotes.length} remotes`);
}
```

## 🏗️ Architecture

SmartGit is built with a clean, modular architecture:

- **`Smartgit`** - Main entry point and repository factory
- **`GitRepo`** - Individual repository operations and analysis
- **`isomorphic-git`** - Underlying Git implementation
- **Environment Detection** - Automatic Node.js environment setup

## 🎯 Use Cases

- **🤖 Automation Scripts** - Automate repository management and analysis
- **🔄 CI/CD Pipelines** - Repository operations in build processes  
- **📊 Code Analysis Tools** - Extract commit data and diff analysis
- **🛠️ Developer Tools** - Build Git-powered development utilities
- **📱 Release Management** - Track versions and generate changelogs

## 🔧 Requirements

- **Node.js** 16+ (Browser support not available)
- **Git repository** access (for clone operations)
- **TypeScript** 4+ (recommended)

## 🤝 API Reference

### Smartgit Class

| Method | Description | Returns |
|--------|-------------|---------|
| `init()` | Initialize the SmartGit instance | `Promise<void>` |
| `createRepoByInit(dir)` | Create new repository | `Promise<GitRepo>` |
| `createRepoByClone(url, dir)` | Clone repository | `Promise<GitRepo>` |
| `createRepoByOpen(dir)` | Open existing repository | `Promise<GitRepo>` |

### GitRepo Class

| Method | Description | Returns |
|--------|-------------|---------|
| `listRemotes()` | List all remotes | `Promise<{remote: string, url: string}[]>` |
| `ensureRemote(name, url)` | Ensure remote exists | `Promise<void>` |
| `getUrlForRemote(name)` | Get URL for remote | `Promise<string>` |
| `pushBranchToRemote(branch, remote)` | Push branch to remote | `Promise<void>` |
| `getUncommittedDiff(excludeFiles?)` | Get uncommitted changes | `Promise<string[]>` |
| `getAllCommitMessages()` | Get commit history | `Promise<CommitInfo[]>` |

## 💡 Pro Tips

- **🔧 Always call `init()`** before using any repository operations
- **📁 Use absolute paths** for repository directories when possible
- **🚫 Exclude large files** from diff analysis using the `excludeFiles` parameter
- **⚡ Batch operations** when working with multiple repositories
- **🛡️ Handle errors gracefully** - network issues can cause clone operations to fail
