chessica

Utilities for assisting with chess games and position data.

This was initially motivated by an interest in transforming a chess diagram (without access to other data other than the side to move, as in a typical chess puzzle) into something that can be fed into a chess engine.

Assembling by hand a position/game in the Forsyth-Edwards Notation (FEN) syntax or worse, the Portable Game Notation (PGN), can be extremely tedious and error prone, something utilities here are intended to help with.

Installing

Add the following to your dependencies:

Leiningen/Boot

[org.clojars.kingnuscodus/chessica "0.1.0-SNAPSHOT"]

Clojure CLI/deps.edn

org.clojars.kingnuscodus/chessica {:mvn/version "0.1.0-SNAPSHOT"}

Usage

From a diagram position, one can enter pieces and occupied squares into the chessica.formats.fen/populate function like so:

(require '[chessica.formats.fen :as fen])

(fen/populate [["rbnnk" "a8 c8 b7 b6 h6"]
              [:p "g7 a6 c5 b4 h4"]
              [:P "a2 b3 c4 d5 e3 g2"]
              ["NNRK" "e7 e4 f1 g1"]]
              "w - - 0 40")

;;=> "r1b5/1n2N1p1/pn5k/2pP4/1pP1N2p/1P2P3/P5P1/5RK1 w - - 0 40"
