Lesser known syntax

[rupert]

Didn’t know about this until the Rubiks cube thread:

Open sourcing the Rubik's cube game

This is super cool! A quick question about the WebGL package, and some of the syntax: fragmentShader : Shader {} Uniforms {} fragmentShader = [glsl| precision mediump float; uniform vec3 color; void main () { gl_FragColor = vec4(color, 1.0); } |] So what exactly is going on in the value of this declaration? Is this valid elm syntax here? Is there a step before the Elm compiler that replaces this with something else? Or is [glsl| some kind of …

Elm can also parse GLSL shaders and has special syntax for handling them:

fragmentShader : Shader {} Uniforms {}
fragmentShader =
    [glsl|
        precision mediump float;
        uniform vec3 color;

        void main () {
          gl_FragColor = vec4(color, 1.0);
        }
    |]
