Added translator support for Modulus token

[vishalghige43]

PR Description

Added support for the modulus operator (%) and the assignment modulus operator (%=) in the CGL translator.

Resolves #116
Working on adding modulus support to the backend.

Shader Sample

This is the PerlinNoise.cgl example code for testing the modulus operator (%) and assignment modulus operator (%=):

shader PerlinNoise {

    // Perlin Noise Function
    float perlinNoise(vec2 p) {
        return fract(sin(dot(p, vec2(12.9898, 78.233))) * 43758.5453);
    }

    // Fragment Shader
    fragment {
        input vec2 vUV;
        output vec4 fragColor;

        void main() {
            float noise = perlinNoise(vUV);
            float height = noise * 10.0;
            vec3 color = vec3(height / 10.0, 1.0 - height / 10.0, 0.0);
            fragColor = vec4(color, 1.0);

            int color2 = 1200 % 10;       //MOD test
            color2 %= 10;                   //ASSIGN_MOD test
        }
    }
}

you have working on MOD operator so only add changes for MOD don't add Assign_MOD here someone else might working on this task . or you can assign this task also to yourself and mention in PR.

[vishalghige43]

Ok, I'll make the changes and only include the modifications for the MOD operator in the PR

[samthakur587]

this is just a demo shader file do not change anything here . write tests only at tests/test_translator/test_codegen/

[vishalghige43]

Got it! I won't make any changes to the demo shader file.
Thanks for the clarification.

[samthakur587]

add tests also for you changes

[samthakur587]

why you removed the Assign_MOD no need to remove it your task it to just add MOD support at translator frontend.
