## 🎮 Usage Examples

### Command-Line Mode (Current)

```bash
# Create an API server with PostgreSQL and JWT auth
cargo-forge new my-api \
  --project-type api-server \
  --author "Jane Doe" \
  --description "My awesome API"

# Create a CLI tool in non-interactive mode (great for CI)
cargo-forge new my-cli \
  --project-type cli-tool \
  --non-interactive

# Initialize a library in current directory
cargo-forge init --project-type library

# Dry run to preview what will be created
cargo-forge new my-project --dry-run

# Use saved configuration
cargo-forge new my-project --from-config ~/.forge/defaults.toml
```

### Advanced Usage

```bash
# Create a workspace with multiple crates
cargo-forge new my-workspace --project-type workspace

# Generate a game with Bevy engine
cargo-forge new my-game --project-type game-engine

# Create an embedded project for STM32
cargo-forge new my-firmware --project-type embedded
```

## 📁 Generated Project Structure

### Example: API Server

```
my-api/
├── src/
│   ├── main.rs           # Application entry point
│   ├── handlers.rs       # HTTP handlers (basic structure)
│   ├── routes.rs         # Route definitions (basic structure)
│   └── models.rs         # Data models (basic structure)
├── config/
│   └── default.toml      # Configuration template
├── tests/                # Test directory
├── .gitignore            # Git ignore file
├── Cargo.toml            # Project manifest with Axum dependencies
└── README.md             # Project documentation
```

## 🔧 Configuration

### Command-Line Options

Cargo-Forge supports various command-line options:

```bash
# Non-interactive mode (great for CI/CD)
cargo-forge new my-project --project-type api-server --non-interactive

# Dry run to preview what will be created
cargo-forge new my-project --project-type library --dry-run

# Initialize in current directory
cargo-forge init --project-type cli-tool
```

### Project Customization

After project creation, you can customize:
- Add dependencies to `Cargo.toml`
- Modify source files to fit your needs
- Update configuration files as needed
- Add additional features and integrations

## 📊 Template Syntax

Cargo-Forge uses Tera templates with custom helpers:

```rust
// Conditional compilation based on features
{% if database %}
use sqlx::{PgPool, postgres::PgPoolOptions};
{% endif %}

// Smart defaults with fallbacks
const PORT: u16 = {{ port | default(value=3000) }};

// Case transformations
mod {{ name | snake_case }};
struct {{ name | pascal_case }};

// Feature combinations
{% if auth and database %}
// Authentication with database backend
{% endif %}
```

## 🧪 Testing

Generated projects include comprehensive test setups:

```bash
# Run all tests
cargo test

# Run with coverage
cargo tarpaulin

# Benchmarks (if enabled)
cargo bench

# Property tests (if enabled)
cargo test --features proptest
```

## 🚢 CI/CD Integration

All project types can include CI/CD configuration:

### GitHub Actions
- Multi-platform testing (Windows, Mac, Linux)
- Rust version matrix (stable, beta, nightly)
- Security audits and dependency checks
- Release automation with cargo-release
- Code coverage with Codecov

### GitLab CI
- Cached dependencies for faster builds
- Parallel job execution
- Deploy stages for different environments
- Container registry integration

## 🐳 Docker Support

Generated Dockerfiles use multi-stage builds for optimal image size:

```dockerfile
# Build stage
FROM rust:1.70 as builder
WORKDIR /app
COPY . .
RUN cargo build --release

# Runtime stage
FROM debian:bookworm-slim
COPY --from=builder /app/target/release/app /usr/local/bin/
CMD ["app"]
```

## 🔒 Security

Cargo-Forge security features:

- No hardcoded secrets in templates
- Secure default configurations
- Environment variable usage for sensitive data
- Security audit integration in CI
- OWASP compliance for web projects

## 🐛 Troubleshooting

### Common Issues

**Q: Command not found after installation**
```bash
# Ensure cargo bin directory is in PATH
export PATH="$HOME/.cargo/bin:$PATH"
```

**Q: Permission denied errors**
```bash
# Check directory permissions
ls -la .
# Use sudo if needed (not recommended)
```

**Q: Template rendering fails**
```bash
# Validate your input
cargo-forge new --dry-run
# Check for special characters in project name
```
