Is castling supported

[Bios-Marcel]

I've tried doing castling and it doesn't seem to work.

I've tried the following:

0-0
0-0-0
00
000
o-o
o-o-o
oo
ooo

EDIT

While the readme answers my question, it didn't work nonetheless and I don't understand why. There was nothing inbetween my king and I see no reason why it wouldn't ahve worked. Is it possible to print the actual reason for being unable to move?

Hi, castling should be fully supported. You can confirm this by testing with the following FEN (specified in your uchess config):

r3k2r/8/8/8/8/8/8/R3K2R w KQkq - 0 1

And then inputting either of the following moves: O-O or O-O-O.

Please note that all of the following conditions are required for a legal castle:

Your king and rook have not moved. Your king is NOT in check. Your king does not pass through check. No pieces between the king and rook.

If you have a board position that meets these criteria, and castling is not working, please provide the FEN (type fen into uchess), and I will be happy to take a look.

Hm thanks for the reply. I am quite sure I met the conditions. In my infinite wisdom I forgot to take a picture or anything ^^'

Ah, no worries, but I'm afraid I can't do much to diagnose it without a board position (at minimum). Move inputs are converted and processed by the notnil/chess package, which has a pretty robust test suite, but there's always a potential for things to get lost in translation. We can leave the issue open if you want to circle back with more data, or we can close it, and you can open a new issue if the problem happens again. I'm fine either way. Thanks!

[Bios-Marcel]

Guess we can close this then. EIther way, is it possible to get more concrete errors instead of just Invalid?

[tmountain]

I'll leave it open and investigate the possibility of doing so. I'll circle back.
