## 🏗️ Architecture

### File Structure
```
src/zexus/
├── cli/
│   └── zpm.py          # CLI interface (Click-based)
└── zpm/
    ├── __init__.py
    ├── package_manager.py  # Core package manager
    ├── registry.py         # Package registry
    ├── installer.py        # Package installer
    └── publisher.py        # Package publisher
```

### Components

1. **CLI (`cli/zpm.py`)**
   - Click-based command-line interface
   - Commands: init, install, uninstall, list, search, publish, info, clean
   - Rich formatting for beautiful output

2. **Package Manager (`zpm/package_manager.py`)**
   - Main ZPM interface
   - Manages project configuration (zexus.json)
   - Coordinates installer and publisher

3. **Registry (`zpm/registry.py`)**
   - Manages package discovery
   - Built-in package definitions
   - Local cache (~/.zpm/cache)
   - Registry URL: https://registry.zexus.dev

4. **Installer (`zpm/installer.py`)**
   - Installs packages to zpm_modules/
   - Resolves dependencies
   - Updates lock files

5. **Publisher (`zpm/publisher.py`)**
   - Publishes packages to registry
   - Package validation
   - Metadata management

## 📦 Available Commands

# Install specific package
zpm install std
zpm install crypto@0.2.0

# Install as dev dependency
zpm install testing -D
```

# Edit zexus.json to add dependencies
{
  "dependencies": {
    "std": "latest",
    "crypto": "0.1.0"
  }
}

# Install all dependencies
python /path/to/src/zexus/cli/zpm.py install
```

### 3. Use Packages in Code
```zexus
# main.zx
use std from "std"
use {encrypt, decrypt} from "crypto"
