Null moves support for PGN files ? #26

Closed XI64 closed 1 year ago

XI64 commented 2 years ago

I am not sure if LucasChess already supports null moves, so far I cannot figure it out how to make lucaschess parse it hence the feature request.

I currently have a "patched up" PGN file (where I basically joined two lichess games into one) and it has a weird move. 13...Rb8 , where the .. after 13. is called a null move which is what I found searching over the internet. The other GUI (SCID vs PC) can infact read this when the .. is replaced with -- and can continue thereon.

However doing the same with lucaschessR2 resulted in a split in the temporary database view, where the first game has no moves altogether and the second game has the moves uptil the null is encountered.

So far on searching, I found out that a few many GUIs support null moves, including lichess & chesscom. So I am curious if lucaschess will also provide some support for it. Thanks!

Small point but by default SCID cannot read .. and will complain about an error. I hope lucaschess' implementation would support both .. and -- if implemented.

P.S. Big fan of your lucaschess and your work!

It is not supported. It's not easy to implement, I imagine it will have a lot of side effects. I will look into it.
