Its law

  • host opener the hand that opened the world may amend any lawrequest.kind == 2 and request.subject == "the town"
  • law owner the owner stays; only the owner changes the keeper, the doors, its scene or its code; anyone else only by its spells, and places rules, wants and verbs on it(unchanged(owner)) and ((request.subject == new.owner) or ((((((((request.kind == 0) or (request.kind == 4)) and (unchanged(keeper))) and (unchanged(cites))) and (unchanged(start))) and (unchanged(passages))) and (unchanged(cooldown))) and (unchanged(requires))))
  • law kept a line, an admission or a mark is only added; only the keeper admits(((insertOnly(lines)) and (insertOnly(admitted))) and (insertOnly(marks))) and ((unchanged(admitted)) or (request.subject == new.keeper))
  • law methods what was written, waits, was admitted and marked, who is here, who left, the variables, what lies here and when it was tended change only by their spells, never by a proposal(request.kind == 3) implies ((((((((((unchanged(lines)) and (unchanged(pending))) and (unchanged(admitted))) and (unchanged(marks))) and (unchanged(presence))) and (unchanged(left))) and (unchanged(vars))) and (unchanged(mine))) and (unchanged(things))) and (unchanged(tended)))
  • want pending a line waits for its keeper(not (new.keeper == "")) and (count(new.pending) >= 1) asks delvetalk {request.object} admit
  • want door it opens onto nothing yetcount(new.cites) == 0 asks delvetalk {request.object} door
  • law kind kind/bond's law holdsunder "kind/bond"
