- [Development Guide](docs/development.md) - Building, testing, and contributing
- [Tree-Sitter](docs/tree-sitter.md) - Syntax highlighting integration

- [Environment Variables](docs/env-vars.md) - Configuration options

## Install

```bash
bun install @opentui/core
```

## Build

```bash
bun run build
```

This creates platform-specific libraries that are automatically loaded by the TypeScript layer.

## Examples

```bash
bun install
bun run src/examples/index.ts
```

## Benchmarks

Run native performance benchmarks:

```bash
bun run bench:native
```

See [src/zig/bench.zig](src/zig/bench.zig) for available options like `--filter` and `--mem`.

## CLI Renderer

### Renderables

Renderables are hierarchical objects that can be positioned, nested, styled and rendered to the terminal:

```typescript
import { createCliRenderer, TextRenderable } from "@opentui/core"

const renderer = await createCliRenderer()

const obj = new TextRenderable(renderer, { id: "my-obj", content: "Hello, world!" })

renderer.root.add(obj)
```
