## Installation

```bash
cargo install ttop
```

## Features

- **Pure Rust**: Zero C dependencies, cross-platform (Linux + macOS)
- **8ms Frame Time**: 2X faster than btop's 16ms target
- **GPU Monitoring**: NVIDIA (via NVML), AMD (via ROCm SMI), Apple Silicon
- **macOS Native**: Full support for Apple Silicon and Intel Macs
- **File Analytics**: Large file detection, duplicates, entropy analysis
- **Deterministic Mode**: Reproducible rendering for testing
- **CIELAB Colors**: Perceptually uniform gradients

## Command Line Options

```
ttop [OPTIONS]

Options:
  -r, --refresh <MS>     Refresh rate in milliseconds [default: 1000]
      --deterministic    Enable deterministic mode for testing
  -c, --config <PATH>    Config file path
      --show-fps         Show frame timing statistics
      --debug            Enable debug logging
  -h, --help             Print help
  -V, --version          Print version
```

## Examples

```bash
# Run with default settings
ttop

# Fast refresh (500ms)
ttop -r 500

# Show frame timing
ttop --show-fps

# Debug mode (logs to stderr)
ttop --debug 2>ttop.log
```

### Programmatic Usage

```rust
use ttop::app::App;

fn main() {
    let mut app = App::new(false, false);
    app.collect_metrics();

    println!("CPU: {} cores", app.cpu.core_count());
    println!("Memory: {:.1} GB", app.mem_total as f64 / 1e9);
}
```
