Windows support about watlings

[EmNudge]

Good call-out! I don't have a windows computer, but I'll get started porting the bash scripts over to node and see if I can get a PR out by EOD. I'm currently at Wasmcon, so it may take longer than I'd like

Let me know if there are still issues on windows for now. I've migrated the bash scripts to node, but I don't have a windows machine of my own right now to verify there aren't any other issues.

Hi, thanks for responding! I tried the patch, but the problem with npm start 001_hello and npm run test in JeffersGlass's comment appeared. I have no idea about the reason currently.

I'm not sure why the spawn behaves erroneously on Windows, and I changed it a little.

Also, according to nodejs/node#37845, the filePath is to be acquired by fileURLToPath. I changed getWastParser.mjs like,

...

      var path = new URL(filePath, import.meta.url).pathname;
      const fileName = path.match(/\/([^\/]+)\.wat$/)[1];
      const wasmPath = fileURLToPath(new URL(`../../.cache/${fileName}.wasm`, import.meta.url))
      path = fileURLToPath(new URL(filePath, import.meta.url))
      
      
      return new Promise((res, rej) => {
        spawn('node', ['node_modules/wabt/bin/wat2wasm', path, '-o', wasmPath], { stdio:'inherit' })

...

, and it compiles 001 successfully. Note that there are backslashes after fileURLToPath on Windows, and I don't want to change the regex part, so I keep the first pathname.

Thanks for the comment! Has the latest commit fixed the issues?

Seems good. It compiles after npm run solve 001_hello and the two tests passed. I have only looked at that puzzle for now, but I suppose others are also fine. (Probably GitHub Actions can help test out other cases on all platforms.)

I think providing a npm run solve all and catching the error during npm run build when some puzzles are not done will be better (or even the watch mode like rustlings), but that is out of the scope of this issue.

Thanks for your work!
