This repository contains source for the GLSL Specification and GLSL extensions.

It is notably for Vulkan related GLSL extensions, but technically for those that do not live in the Khronos registries for OpenGL or OpenGL ES.

== Differences between Gitlab and GitHub repositories

• The Khronos internal gitlab version of this repository is a (lagging) mirror of the public repository at https://github.com/KhronosGroup/GLSL, and additionally contains GLSL spec source that is not yet published.
• Once something moves to GitHub, the GitHub version will be considered the true source of the extension.

== This Project Contains

• new shading language extension proposals and discussions
• issue tracking for these unreleased extensions
