@aladdin-add This is a huge problem. Take this case fo\u0072 = x;. It get printed into for(; ; ). It's actually invalid syntax

[aladdin-add]

in non-error-recovery mode, please do not ignore the errors silently! just throw the errors?

[KFlash]

A printer shouldn't run in a error-recovery mode. Can you add a error handler in the test runner for this?

bar ? (, => {}) : baz; throws on null because the : token doesn't exist in the CST tree.

@aladdin-add this is how I do it locally. It will throw an error an never print the invalid syntax. Can you adopt this?

    const source = parse("bar ? (, => {}) : baz;",
      'root',
      Context.None,
      false,
      { allowTypes: true },
      function (a: any, b: any, c: any, d: any) {
        throw b + '(' + c + ', ' + d + ')';
      }
    );
    console.log(printSourceFile(source));
