Help making my old wrapper.js work with the latest jslint.mjs

[AlbertWiersch]

Can someone who knows a lot more about JavaScript than I do help me make this old wrapper (which worked with jslint.js) work with the latest jslint.mjs?

Here is the current wrapper.js:
https://www.htmlvalidator.com/downloads/wrapper.js

It's usually called like this (to test file jstest.js):
node.exe wrapper.js --format="error, line {l}, char {c}:{m}" --indent=1 "jstest.js"

Much appreciated.

Thanks.

here's a new wrapper2.js that does mostly what you want. note the old options indent, maxerr, maxlen, predef were removed from jslint (since ~2015). please goto https://www.jslint.com to checkup on the latest options.

#!/usr/bin/env node
/*
 * wrapper2.js
 *
 * CommonJS command-line wrapper for jslint.mjs
 *
 * Example usage:

node wrapper2.js --for --long --globals=caches,indexedDb --maxerr=20 jquery.js

 */

/*jslint beta, indent2, node*/

(async function () {
  var file;
  var globals = [];
  var jslint;
  var maxerr = Infinity;
  var options = {};
  var result;
  var source;

// Import JSLint.

  jslint = await import("./jslint.mjs");
  jslint = jslint.default;

// Parse process.argv.

  process.argv.slice(2).forEach(function (arg) {

// Parse globals=xxx,xxx,...

    if (arg.startsWith("--globals=")) {
      globals = arg.replace("--globals=", "").split(",");
      return;
    }

// Parse maxerr=xxx.

    if (arg.startsWith("--maxerr=")) {
      maxerr = Number(arg.split("=")[1]);
      return;
    }

// Parse regular jslint options.

    if (arg.startsWith("--")) {
      options[arg.slice(2)] = true;
      return;
    }

// Parse file.

    file = arg;
  });

// Read file.

  source = await require("fs").promises.readFile(file, "utf8");

// JSLint source.

  result = jslint.jslint(source, options, globals);

// Print warnings.

  result.warnings.slice(0, maxerr).forEach(function ({
    column,
    line,
    line_source, // optional evidence
    message
  }, ii) {
    console.error(`${ii + 1}. error, line ${line}, char ${column}:${message}`);
    console.error(`  evidence: ${line_source.trim().slice(0, 80)}`);
    console.error();
  });
}());

Thank you. That was a big help. I've modified it a bit to fit my needs and desires.
