GLSL quasiquoting.

This crate exports a procedural macro: glsl!. It enables quasiquoting by allowing you to embed GLSL source code directly into rust via the syntax:

ignore glsl!{ // your GLSL code here void main() { } }

! The glsl! macro accepts the GLSL code directly. You can then write plain GLSL. Especially, ! since version 0.2, the macro accepts plain GLSL pragmas (both #version and #extension).

The glsl! procedural macro resolves at compile-time to glsl::syntax::TranslationUnit, allowing you to manipulate the GLSL AST directly. Feel free to have a look at the glsl crate for further information.

Getting started

Add the following to your dependencies in your Cargo.toml:

ignore glsl = "0.9" glsl-quasiquote = "0.2"

Then, you currently need to have a nightly compiler and the following feature enabled:

```ignore

![feature(procmacrohygiene)]

```

Then, depending on which you’re using the 2018 edition or not:

Non-2018 edition

```ignore extern crate glsl;

[macrouse] extern crate glslquasiquote;

```

2018 edition

ignore extern crate glsl; use glsl_quasiquote::glsl;
