Zig OpenGL Bindings

An OpenGL bindings generator for Zig. Includes dynamically loading.

Usage: build.zig

In your build.zig, you can use the createBindingsModule method from the generator's build script:

const opengl_bindings_dependency = b.dependency("opengl_bindings", .{
    .api = "gles2",
    .version = "GL_ES_VERSION_3_0",
});
...
module.addImport("gl", opengl_bindings_dependency.module("gl"));

Usage: Standalone

Building

Building the standalone binary is as simple as:

zig build -Doptimize=ReleaseFast

You can then run the generator with

./zig-out/bin/opengl-bindings gles2 GL_ES_VERSION_3_0 output.zig

Usage: Loading

Once the module has been imported, e.g. const gl = @import("gl"), you can use gl.init() to load all relevant functions.

• All GL functions are the same as in the reference except that the gl prefix is removed. For instance: glClear becomes gl.clear()

• All enums are the same as in the reference, except that the GL_ prefix is removed. For instance: GL_RGBA becomes gl.RGBA

Static Interface

You can generate a static interface (for example, calling WASM functions) by using either .static = true in the create module config or passing --static to the standalone generator.
