chess's Issues

Documentation link in README doesn't work

Hello @pioz

The documentation link in the README https://github.com/pioz/chess/blob/master/README.md?plain=1#L37 is returning a 404.

**Documentation** is available **[here](http://pioz.github.com/chess)**.

Is there a bug in the GitHub Pages generation of the documentation?

Thanks,
Tim

Ruby version

Hi!
In the description says Ruby 1.9 or higher is needed. However, I am using 1.9 and it does not work. In fact some notation used in the code seems to be for Ruby 2.x:

Uncaught exception: /home/raquel/.rvm/gems/ruby-1.9.3-p551@codelearn/gems/chess-0.2.2/lib/chess/pgn.rb:42: syntax error, unexpected tLABEL
    def initialize(filename = nil, check_moves: false)

Any workaround or version that actually works with Ruby 1.9?

Deploy new version to ruby-gems

Hey, is there a chance you could deploy the new chess gem version (chess-0.0.5) to ruby-gems? Thanks!

Segmentation fault in move generator

Generating possible moves for this position: rnbqkbnr/1ppppppp/8/8/pP2P3/P7/2PP1PPP/RNBQKBNR w KQkq - 0 3' and the C2 field leads to a segmentation fault.

I added a failing spec here: kamil-gwozdz@a452c9f

I tested it with ruby 2.7.2.

Ilegal move error

Dear pioz,

Thank you so much for providing such a great chess library to the Ruby community. Upon testing exception handling, I believe I found a small bug, and hope you can enlighten me in this regard. When an invalid move is entered during the early stages of the game in the format "d2d4q", my script throws an error message accordingly: "Illegal Move". However, the game object still accepts this string (it can be accessed with g.moves), and that causes some downstream errors. It actually considers the move a valid one, discarding only the piece promotion character (d2d4). Also, when a move is entered in the format "e4" or "2e4", the game object accepts them as legal, but the system still throws the Illegal Move exception. Any help would be greatly appreciated. Thank you and keep up the excellent work!

I'm running into a roadblock with this gem where if I try to require it in any of my .rb's, i get thrown the same error. I've uninstalled and reinstalled multiple times, and these are the errors I get:

chess/gnuchess.rb:53: warning: regexp has invalid interval

chess/gnuchess.rb:53: warning: regexp has invalid interval

There are some regexp with invalid intervals.

Is the code ruby 1.9.x or higher only? If so a proper check might be in order.

Or, to have the code work on both versions (including 1.8.x) and change the regexp there.

Memory issue on Ubuntu 14.04.1

Hey,

So I've been running into a reproducible issue on Ubuntu 14.04.1, with Ruby 2.1.0 through 2.2.0 (haven't tested before ruby 2.1.0) where every time I try and use the set_fen method, ruby crashes with a Error in irb': free(): invalid next size (fast): 0x00007f2f89f17ae0` (obviously the memory location changes every time). I've been working around this in the mean time by modifying the pgn class to accept strings while I try and figure out the issue, however, I'm running out of ideas, and since you wrote the C library backing the gem I was wondering if you had any thoughts on it?

I'm currently working on setting up a docker container to reproduce the error for you, but I figured I'd start the discussion now.

Thanks!

When loading a FEN where the board is in Checkmate, the status is :in_progress

Title pretty much sums it up. I believe the expected status should be :color_won, not :in_progress. Test code below.

require 'chess'
g = Chess::Game.load_fen('rnb1kbnr/pppp1ppp/4p3/8/5PPq/8/PPPPP2P/RNBQKBNR w KQkq - 1 3')
g.status
=> :in_progress

Thanks!

Lichess coordinate notation for castling

Ran into issues with coordinate notation using data from Lichess. The castling's presented as e8h8 instead of e8g8: example Wikipedia and this gem follow the latter. Not sure if this is some wider spread alternative convention or a Lichess oddity.

Any way made a local quickfix to get these games to parse. Here's the patch I used, in case interested:

Taking back a move

Dear Enrico, how can I take back a move?

Can this library handle resigning?

I'm testing the library using a PGN with this moves:

[Event "?"]
[Site "?"]
[Date "2013.03.09"]
[White "White"]
[Black "Black"]
[Result "0-1"]
[WhiteElo "1364"]
[BlackElo "1649"]
[TimeControl "1 in 3 days"]
[Termination "Black won by resignation"]

1.e4 c5 {Thematic Game - This is the starting position.} 
 2.c4 Nc6 3.Nf3 e6 4.Be2 Nf6 5.e5 Ng4 6.d4 cxd4 7.Bf4 Qa5+ 8.Qd2 Bb4 9.Nc3 dxc3 0-1

However a.over? returns false.

Load PGN string instead of file?

Hi there!

I was wondering if there is a way to load the pgn to create the game in string format instead of having to create a file.

Thanks!

Could use move generation

For a chess library, it seems the absence of legal move generation is an is an oversight. Hopefully it would be easy to add. It's the only thing keeping this library from being truly useful.

invalid FEN generation?

Hello and thank you for this valuable library!

I believe I have found a case where an invalid FEN is generated. In the example below, after the move Qxh8, black is not legally able to castle (both black rooks are no longer in their original positions) and yet the generated FEN string indicates black can castle kingside: KQk.

> game = Chess::Game.load_fen("2b1kbnr/rpq1pp1p/2n3p1/8/3Q4/2P5/PP3PPP/RN2KBNR w KQk - 0 9")
=> #<Chess::Game:0x00007f85c9bcb910>

Game#to_s causing a buffer overflow in Heroku

It's not happening when run locally, either with straight ruby or running under foreman, but on hosted Heroku, Game cannot be output as a string without causing a buffer overflow. I've created the simplest possible demonstration of this behavior here: https://github.com/jer/chess-error

I've tried working on this myself, but I can't seem to even run the unit tests on a fresh checkout :( I'd be happy to help debug if I can get a little help building it.

Here is the output from the Heroku run:

Pawn cannot turn into a queen

Hello,

I ran into an issue while playing.
The Chess::IllegalMoveError is raised when the pawn tries to go to the end of the board and become a queen.

Algebraic input

Dear Pioz, does Chess gem have a method that allows the user to enter a move in algebraic format (e.g. Nxf6) and get the ouput in coordinate format (G8F6)? By the way, this gem is great.

PGN is not in a standard format

Hi, sorry for opening so many issues but this is the most downloaded chess gem and I do not understand how there are so many things that seem irregular.

PGN is supposed to be a string that looks something like:

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 {This opening is called the Ruy Lopez.}
2. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. h3 Nb8 10. d4 Nbd7
3. c4 c6 12. cxb5 axb5 13. Nc3 Bb7 14. Bg5 b4 15. Nb1 h6 16. Bh4 c5 17. dxe5
   Nxe4 18. Bxe7 Qxe7 19. exd6 Qf6 20. Nbd2 Nxd6 21. Nc4 Nxc4 22. Bxc4 Nb6
4. Ne5 Rae8 24. Bxf7+ Rxf7 25. Nxf7 Rxe1+ 26. Qxe1 Kxf7 27. Qe3 Qg5 28. Qxg5
   hxg5 29. b3 Ke6 30. a3 Kd6 31. axb4 cxb4 32. Ra5 Nd5 33. f3 Bc8 34. Kf2 Bf5
5. Ra7 g6 36. Ra6+ Kc5 37. Ke1 Nf4 38. g3 Nxh3 39. Kd2 Kb5 40. Rd6 Kc5 41. Ra6
   Nf2 42. g4 Bd3 43. Re6 1/2-1/2

However, this gem seems to use a custom format (not real PGN) making it incompatible with other tools (chess.js for instance)

I am wrong or is there a way to get the correct PGN string out of a PGN object?
