ppn 0.3.0

New features

• Macros may now reference other macros (recursive macros). Macro values are fully expanded at parse time; circular references produce an error.

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

  • piecepack_parser()

Bug fixes and minor improvements

• Fixes bug in process_exclamation_move() (e.g. !PieceId moves).
• Eliminated use of deprecated ppdf functions.

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).

ppn 0.1.1

Functions for reading/writing Portable Piecepack Notation (PPN) files:

• read_ppn() parses Portable Piecepack Notation (PPN) files.
• write_ppn() writes Portable Piecepack Notation files.

Functions for visualizing moves in a parsed game:

• plot_move() visualizes moves in a parsed game via piecepackr::render_piece().
• animate_game() visualizes moves in a parsed game via piecepackr::animate_game().
• cat_move() and cat_game() visualizes moves in a parsed game via ppcli::cat_piece().

Interactive PPN viewers:

• view_game() provides interactive PPN viewers with a choice of a {shiny} app and a {cli} command-line interface.
