the commands that the engine has received etc. In debug mode the engine should send additional infos to the GUI, e.g. Switch the debug mode of the engine on and off. If no uciok is sent within a certain time period, the engine task will be killed by the GUI. To tell the engine to switch to uci mode.Īfter receiving the uci command the engine must identify itself with the id commandĪnd send the option commands to tell the GUI which engine settings the engine supports if any.Īfter that the engine should send uciok to acknowledge the uci mode.
This will be sent once as a first command after program boot Tell engine to use the uci (universal chess interface), These are all the command the engine gets from the interface. The move format is in long algebraic notation.Ī nullmove from the Engine to the GUI should be sent as 0000.Įxamples: e2e4, e7e5, e1g1 (white short castling), e7e8q (for promotion) Not calculating, it should also just ignore it.
