golo 1.0.2

golo: ^1.0.2 copied to clipboard

• Game: add depth (max depth), currentDepth, parentOf, and depthOf helpers.
• Game: remove({nodeId, includeSelf}) can now keep a node while clearing descendants and still guards against removing the root.
• SgfTree: add depth, currentDepth, and depthOf(id) helpers mirroring the Game API.
• Tests: extend coverage for depth helpers and removal options.

• Game: add remove({nodeId}) to delete a node or truncate from root.
• SgfTree: add removeFrom(id, {includeSelf}) for recursive deletion.
• Game: add navigation helpers goNext, goAt (variation index), goBack, goSibling.
• Game: currentPlayer is now computed from the last move (no mutable state).
• Tests: add coverage for removal and navigation; minor assertions tightened.

• Breaking: Renamed and consolidated core APIs.

  • Coordinates now use Vertex record (({int x, int y})). Many method signatures changed (e.g., Board.get/has/set, Game.play, Node helpers).
  • Board.makeMove is now pure and returns a new Board instead of mutating in place; it throws IllegalMoveException with an IllegalMoveReason.
  • BoardTree returns cloned snapshots from [] and stores clones on []=; snapshots should be treated as immutable.
  • SgfTree/Node: Node IDs are non-null int; get/set helpers live on Node (moved from tree-level usage). Node data shape is Map<String, List<String>>.
  • SGF writer filters to uppercase property identifiers; lower-case custom keys are no longer emitted unless uppercase.

• Added: High-level Game API with SGF I/O and history.

  • Game.play, Game.pass, Game.undo, Game.boardAt.
  • Root metadata helpers (e.g., rule, application, players, result, komi, handicap, etc.).
  • Game.toSgf() and Game.fromSgf() (imports main line, applies setup).

• Added: SGF tokenizer and parser.

  • sgf.Token, sgf.TokenIterator, sgf.Parser, sgf.RecursiveNode.
  • Parser normalizes property identifiers to uppercase and unescapes SGF values.
  • Example: example/sgf_player.dart (interactive mainline navigator).

• Added: Board utilities and rule enforcement.

  • IllegalMoveException + IllegalMoveReason (overwrite/ko/suicide/outOfBoard).
  • getLiberties, getChain, getNeighbors, getRelatedChains, isValid.
  • copyWith, clone, diff, parseVertex, stringifyVertex.
  • getHandicapPlacement (Tygem ordering supported via flag).

• Changed: SGF serialization.

  • Pretty parentheses + indentation; only uppercase property IDs are written.

• Docs/Examples: Added example/golo_repl.dart, updated README and LICENSE.

Migration notes

• Replace any previous point type with Vertex: (x: x, y: y).
• Update uses of Board.makeMove(...) to handle the returned board (do not rely on mutation) and catch IllegalMoveException as needed.
• Treat BoardTree snapshots as immutable; write back via tree[id] = board.
• If you relied on lower-case SGF properties, use uppercase identifiers.

• Initial version.
