ppn 0.2.1

Deprecated features

• Custom movetext parsers should now be of the form name_parser()
  instead of parser_name().

New features

• We now export (and document their arguments) the following movetext parsers:

  • alquerque_parser()
  • default_parser()
  • checker_parser()
  • chess_parser()
  • domino_parser()
  • go_parser()
  • marble_parser()
  • morris_parser()
  • tarot_parser()

Bug fixes and minor improvements

• The following tweaks to PPN:

  • If a PieceSpec is missing Piece and is a colored suit
    and it's side is not l, r, or x then it is now assumed to
    be a "bit" (instead of a "tile").
  • If a "marbles" "bit" is missing its rank assume that
    its rank is 9L (i.e. 1" marble when visualized by {piecepackr}).
  • The Unicode symbols for checker kings (i.e. ⛁ and ⛃) are now interpreted
    as checker bits face up (instead as not being interpreted as checker pieces at all).
  • Now handles the Unicode symbols for rotated chess pieces.
  • Now handles the Unicode symbols for "neutral" chess pieces (assigns to the suit 1L aka the "red" suit).
