Of .stringify() and dates/timestamps

[nulltoken]

Hello,

Pasting the following in https://npm.runkit.com/yaml

var yaml=require("yaml")
var opts = {version: '1.1'};

var inObj = {
  canonical: "2001-12-15T02:59:43.1Z",
  validIso8601: "2001-12-14t21:59:43.10-05:00",
  spaceSeparated: "2001-12-14 21:59:43.10 -5",
  noTimeZone: "2001-12-15 2:59:43.10",
  dateUTC: "2002-12-14",
  b: "2012-10-12T12:43:51Z",
  c: "2012-10-12T12:43:51.1",
  int: 1,
  bool: true
};

console.log(inObj)

var a=yaml.stringify(inObj, opts)
console.log(a)

var outObj = yaml.parse(a, opts);
console.log(outObj)

produces the following

@eemeli From #117, I thought I understood that specifying version as 1.1 would help disambiguate this and would help me keeping things that look like timestamps in a quoted form.

I may have misunderstood your explanations.

Help? 🙏

Aah, bother. Sorry for having left this unanswered so long. That's a bug, caused by an incorrect optimisation in the stringifier. The re-parsing test was getting skipped if the string didn't match the regexp ^[\w.+-]+$. That's a valid assumption to make for YAML 1.2, but not for 1.1. I've now left it out.
