Accept next tuesday +10 days

[HendrikJan]

I have a combined PHP and Javascript application.

Currently PHP supports "next tuesday +10 days" or variations on that (using strtotime).
It seems that chrono does not, unless I am missing something.

Chrono supports "+10 days" or "next tuesday", but not the combinations of the two.

A workaround for me is currently this:

// Read a PHP date like "next tuesday +1 day"
function readPHPDate(dateStr) {
  const match = dateStr.match(/(.*)([+-].*)/);

  if (match) {
    // Get the chrono +days
    const date = chrono.parseDate(match[1]);
    // Return result as string
    const offset = chrono.parseDate(match[2], date);
    // Get the chrono date
    return offset;
  }

  return chrono.parseDate(dateStr);
}

Hello.

Chrono supports "X before/after Y" (e.g. "10 days after next Friday") in ENMergeRelativeDateRefiner.ts. It is possible to extend the module to support your case.

I can work on it when I have more free time, but also feel free to submit a PR.

I've looked into the code.
Since the new relative time "+10 days" comes after the absolute date ("today +10 days"), while the existing code handles the situation where it comes before ("10 days before today"), it is not a trivial change.
If you are willing and have time to look into this, I would appreciate it.
