Instructions for using the Chess Program


Log in to your CS account.

Then create a directory in your account:
     mkdir chess

Go into that directory:
     cd chess

Copy the chess program from the course account into your chess directory:
     cp ~cs181/public_html/handouts/chess-solns.lisp .
(You need to type the final period!)

Start up the "aclemacs" program:
     aclemacs&

After it finishes loading:
     Hit the "Esc" key, followed by the "x" key.
     Then type:  fi:common-lisp
     Then hit the "Enter" key about six or seven times,
        until you see the Lisp prompt:  CL-USER(1):
     Compile the chess program:  (compile-file "chess-solns")
     Load the chess program:  (load "chess-solns")
     
Now you're ready to play:
     (setf g (init-game))
    
To do a move when it's your turn (white):
     (do-move! g t 1 4 3 4)   <--- move piece from row 1, col 4 to row 3, col 4

To ask the computer to do the next move:
     (apply #'do-move! g nil (compute-move g))

Etc.

If it gets stuck in an endless loop or becomes unresponsive, hold down
the Ctrl key and hit C a few times.

To exit the Lisp session, type:  (exit)

To exit aclemacs, just close the window (like you do with emacs).
