[Feature Request] GlSL macro

[tmvkrpxl0]

yew has html macro like this:

Which allows rust compiler to verify syntax of html code and even highlight errors. Referencing and invoking rust code inside html also works. I think it would be nice if glium had something similar.
I admit that it would be hard to implement such thing in glium, but still, it would greatly simplify implementing shader, as not only devs can work on it in rust file, but it can also be extended to treat uniforms also as variable reference

let t = 0.0; // this will be uniform
let shader = program! {
  vertex! {
    in vec2 position;
    
    uniform float t;
    
    void main() {
        vec2 pos = position;
        pos.x += t;
        gl_Position = vec4(pos, 0.0, 1.0);
    }
  }
  fragment! {
  ...
  }
}

If variable t in this case is i32, it would cause compiler error

Sorry, I should've researched more, I've just discovered that there's macro called program already.
Still, expanding its capability to such level would be nice addition

Yeah, it does sounds a bit too ambitious for glium. A big feature like this should also probably go in a separate crate to keep glium somewhat small.

For future record, thees already implemented macro for it
