chessica.coordinates — org.clojars.kingnuscodus/chessica 0.1.3-SNAPSHOT

Translates chess square coordinates between cartesian, row-column indexes and chess board rank-file formats.

Note the convention of using the 8th rank of the chess board as the first row of the cartesian representation.

->col-idx clj

Function translating a chess file letter character into a cartesian, zero-based column index, e.g. \a -> 0

->file clj

Function translating a cartesian column index into a chess file letter character, e.g. 0 -> \a

->file-rank-str clj

(->file-rank-str [row col])

->file-str clj

(->file-str col-idx)

Function translating a cartesian column index into a chess file letter character as a string, e.g. 0 -> "a".

->rank clj

(->rank row-idx)

Function translating a top-down, zero-based cartesian index into a chess rank integer, e.g. row 7 -> 1.

->rank-char clj

Function translating a top-down, zero-based cartesian index into a chess rank character, e.g. row 7 -> \1.

->rank-str clj

(->rank-str row)

Function translating a top-down, zero-based cartesian index into a chess rank character as a string, e.g. row 7 -> "1".

->row-col-idxs clj

(->row-col-idxs [file rank])

Converts a rank-file string or char tuple, into a cartiesian [row column] vector of indexes.

->row-idx clj

Function translating a (bottom up) chess rank into a top down, zero-based row index, e.g. rank 8 -> 0.
