PHP library that wraps the [**open-gl**](https://github.com/php-io-extensions/open-gl) extension (`ext-opengl`) with global helpers, enums, and a static wrapper class. Every helper delegates to `Microscrap\Bindings\OpenGL\GL`, which is the only layer that calls `Opengl\GL\GL`.

Token constants from the OpenGL SDK (`GL_COLOR_BUFFER_BIT`, …) live here as backed PHP enums — the native extension does not expose them.

This is the **bindings** package — not the native extension. Ecosystem docs: [`0.7.x`](https://scrapyard-io.projectsaturnstudios.com/ecosystem/microscrap/open-gl/0.7.x/overview).

Highlights
----------

[](#highlights)

- Two calling styles — exact C names (`glClearColor(...)`) or static wrapper (`GL::clearColor(...)`)
- Named objects stay as extension DTOs (`Opengl\GL\GlBuffer`, `GlTexture`, `GlShader`, `GlProgram`) with public `fd`
- Enum layer transcribed from the OpenGL SDK / `gl.h` for the slice-1 API surface
- C-style error handling: no exceptions in `src/`; details via `glGetError()`
- Coverage drift + style audit Pest guards keep the wrap 1:1 with the extension

Requirements
------------

[](#requirements)

- PHP 8.3+
- **ext-opengl** ^0.7.0 — install from [php-io-extensions/open-gl](https://github.com/php-io-extensions/open-gl)
- A current OpenGL context from **glfw** or **sdl3** before draw calls succeed

Installation
------------

[](#installation)

Confirm **ext-opengl** is loaded:

```
php -m | grep opengl
```

```
composer require microscrap/open-gl
```

Composer autoloads helper files in `src/Helpers/`, registering global `gl*` functions when the package is installed. Helpers are only defined if the name is not already taken (`function_exists` guard).

> **Note:** `microscrap/glfw` also defines a small subset of `gl*` helpers for visual proofs. Prefer this package as the canonical OpenGL binding; load order decides which definition wins under the guard.

The two calling styles
----------------------

[](#the-two-calling-styles)

**C-ish** — global functions with exact OpenGL C / extension names:

```
use Microscrap\Bindings\OpenGL\Enums\ClearBufferMask;
use Microscrap\Bindings\OpenGL\Enums\StringName;

glClearColor(0.1, 0.1, 0.12, 1.0);
glClear(ClearBufferMask::GL_COLOR_BUFFER_BIT);
echo glGetString(StringName::GL_VERSION);
```

**OO-ish** — static wrapper class, same behavior:

```
use Microscrap\Bindings\OpenGL\GL;
use Microscrap\Bindings\OpenGL\Enums\ClearBufferMask;
use Microscrap\Bindings\OpenGL\Enums\StringName;

GL::clearColor(0.1, 0.1, 0.12, 1.0);
GL::clear(ClearBufferMask::GL_COLOR_BUFFER_BIT);
echo GL::getString(StringName::GL_VERSION);
```

Helpers never touch the extension directly; they delegate one-to-one to `GL`, which is the only layer calling `Opengl\GL\GL`. Flag/enum parameters take `EnumType|int`.

### Name transforms

[](#name-transforms)

- Wrapper methods drop the `gl` prefix: `glClearColor` → `GL::clearColor()`.
- Helpers use the exact extension method name (`glClearColor()`, `glUseProgramNone()`).

CI runs the same suite on PHP 8.3–8.5 (coverage uses the committed extension method snapshot when `ext-opengl` is not loaded).
