How to run: place repo folder in project directory. run ./check from within repo folder (run chmod +x check if necessary) How to write your own tests: Use existing tests as a template to create .glsl and .dat files. Create .out file either by running your program or computing the result by hand. To verify your .out file is correct: 1) copy and paste your .glsl file here: http://shdr.bkcore.com/ 2) Add 'precision highp float;' as the first line in the file 3) Add the following main method at the bottom void main(){ if(_YourFunctionHere_() == _YourOuputHere_) gl_FragColor = vec4(0,1,0,1.0); // green else gl_FragColor = vec4(1,0,0,1.0); // red } If your output is correct you will see a green monkey head. If your output is wrong, it'll be red. Once you verify your test case is correct, create a pull request to share it. Example (using swizzle.glsl): /******Original test case *******/ vec2 v = // = .5, 1.5 float test(){ vec3 t; t = v.xxx + v.xxx; // t = (1, 1, 1) vec3 f; f = t; // f = (1, 1, 1) f.z = -1.0; // f = (1, 1, -1) t.z = 0.0; // t = (1, 1, 0) t.x = t.z + t.y; // t = (0, 1, -1) t.yx = t.xy + t.xy; // t = (2, 0, -1) return t.x; // 2.0 } /***** Input for online compiler ******/ precision highp float; // This is always required for shdr.bkcore.com vec2 v = vec2(.5, 1.5); // Add initializers that were declared in .dat file float test(){ vec3 t; t = v.xxx + v.xxx; vec3 f; f = t; f.z = -1.0; t.z = 0.0; t.x = t.z + t.y; t.yx = t.xy + t.xy; return t.x; } void main() { if(test() == 2.0) // Assert function call returns expected value gl_FragColor = vec4(0,1,0,1.0); // green else gl_FragColor = vec4(1,0,0,1.0); // red }
