Building ”modern” tsc

[helander]

Have anyone compiled a ”modern” version of tsc (typescript compiler) with qjsc? The patch file available in the tar mentioned in the documentation does not ”work” with the ”current” typescript package.

Thank you 😃

We could also add to the returned getQuickJSSystem object the following methods:

    return {
      //...
      getWidthOfTerminal() {
        const [width, _height] = os.ttyGetWinSize(1);
        return width;
      },
      writeOutputIsTTY() {
        return os.isatty(1);
      },
      // readFile: function (path, _encoding) { ...
    }

to get the same output color/layout as node

Also, readFile and writeFile shall not fail silently in order for tsc to create intermediate folder when outputing file

      readFile: function (path, _encoding) {
        const f = std.open(path, "r");
        if (!f)return void 0;
        const ret = f.readAsString();
        f.close();
        return ret;
      },
      writeFile: function (path, data, writeByteOrderMark) {
        const f = std.open(path, "w+");
        if (!f)
          throw new Error(`Unable to write ${path}`);
        f.puts(data);
        f.close();
      },

I'll try to upstream the patch so (at least) the qjs --std tsc.js ... could work out of the box

@zeromake is the removal of "use strict"; to be in sloppy mode necessary ?
