The JS script I wrote to modify the stdlib:


function assert(b) {
    if (!b)
        throw new Error;
}

const ignore = ["char", "short", "short", "half"];

let lines = readFile("/Volumes/Data/Desktop/stdlib.wsl").split("\n");

let result = "";
let currentFunction = null;
let blockNest = 0;
for (let line of lines) {
    if (!currentFunction) {
        if (line.indexOf("{") >= 0) {
            currentFunction = [line];
            blockNest = 1;
        } else {
            let ok = true;
            if (line.indexOf("/*") < 0) {
                for (let word of ignore) {
                    if (line.indexOf(word) >= 0)
                        ok = false;
                }
            }
            if (ok)
                result += `${line}\n`;
        }

        continue;
    }

    currentFunction.push(line);

    if (line.indexOf("{") >= 0) {
        ++blockNest;
        assert(line.indexOf("}") < 0);
    }

    if (line.indexOf("}") >= 0) {
        assert(line.indexOf("{") < 0);
        --blockNest;
        if (!blockNest) {
            let functionText = currentFunction.join("\n");
            let ok = true;
            for (let word of ignore) {
                if (functionText.indexOf(word) >= 0)
                    ok = false;
            }
            if (ok)
                result += `${functionText}\n`;
            currentFunction = null;
        }
    }
}

print(result);

I can't make inline comments, so I'll comment here.

We need to keep the TextureFormats, but make sure that whenever they're read, they get padded out to wider types. It's not immediately obvious how to do this, so let's not modify this patch but file a follow-up to make sure that all the texture types work properly.

Can we add a non-exhaustive test to make sure that the types don't exist and don't work?
