Convert the giant blob of invalid JSON Robo3T gives you into something consumable.

• First:
  • Find... (?:ISODate|ObjectId)\(("[^"]+")\) (BSON types)
  • And replace with... $1 (the non-ignored capture group)
• Second:
  • Find... (/\*\s+\d+\s+\*/) (index comments)
  • And replace with... , (comma to separate array elements)
• Finally
• Remove the stray comma where /* 1 */ used to be

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

The Challenge
-------------
Given the following riddle, write a regular expression describing all possible answers,
assuming you never make a move which simply undoes the last one you made.

The Riddle
----------
You are on your way somewhere, taking with you your cabbage, goat, and wolf, as always.
You come upon a river and are compelled to cross it, but you can only carry one of the
three companions at a time. None of them can swim because this isn't THAT kind of riddle.
