Examples

JavaScript
var canvas = document.getElementById("canvas");
var gl = canvas.getContext("webgl");

var shader = gl.createShader(gl.FRAGMENT_SHADER);
gl.shaderSource(shader, "void main() { gl_FragColor = vec4(gl_FragCoord.x, 0.0, 0.0, 1.0); }");
gl.compileShader(shader);

var src = gl.getExtension('WEBGL_debug_shaders').getTranslatedShaderSource(shader);
console.log(src);
// "void main(){
// (gl_FragColor = vec4(gl_FragCoord.x, 0.0, 0.0, 1.0));
// }"
