multistockfish 0.5.0

Multiple flavors of Stockfish Engine

0.5.0

Breaking changes:

• Stockfish.start now sends the "uci" command to the engine and waits for it to respond with "uciok". When using the library, do not send "uci" yourself anymore, as that would reset UCI options.

Migration:

// Before
await Stockfish.instance.start(flavor: StockfishFlavor.variant, variant: 'atomic');
// stockfish is ready, enable uci protocol.
Stockfish.instance.stdin = 'uci';

// After
await Stockfish.instance.start(flavor: StockfishFlavor.variant, variant: 'atomic');
// "uci" command has already been sent to `stdin` internally, stockfish is ready and in uci mode.

0.4.0

• Update latest Stockfish to version 18.

Breaking changes:

• Stockfish is now a singleton. Use Stockfish.instance.
• Configuration (flavor, variant, bigNetPath, smallNetPath) moved from the constructor to start().
• Removed StockfishState.disposed. After calling quit(), the state returns to initial and the engine can be restarted.
• start() throws a StateError if the engine is already running. Call quit() first.
• The stdout stream now persists across restarts - listeners don't need to re-subscribe.

Migration:

// Before
final stockfish = Stockfish(flavor: StockfishFlavor.variant, variant: 'atomic');
// listen to stockfish state and wait for it to be ready
stockfish.stdin = 'uci';

// After
await Stockfish.instance.start(flavor: StockfishFlavor.variant, variant: 'atomic');
// stockfish is ready
Stockfish.instance.stdin = 'uci';
