Original-posting-by: erlkonig@walt.cc.utexas.edu (Christopher North-Keys)
Original-subject: New file for terminal display of Gnuchess: nuxdisp.c
Reposted-by: emv@math.lsa.umich.edu (Edward Vielmetti)
[This is a patch to from gnu.chess.]
I would have just published diffs to uxdisp.c, but the diffs ran longer
than the file. The new module is not thoroughly tested, nor have the
features been reduced to the more elegant minimum, but it's very spiffy.
[ Produced on a Sun3/150 running SunOS 4.0.3 ]
[ Be careful to kill any .sig at the end of this posting ]
Add the following makefile targets, being sure to retain the <tabs>:
gnuchessn: gnuchess.o nuxdsp.o $(NEW)
$(CC) $(CFLAGS) -o gnuchessn gnuchess.o nuxdsp.o $(NEW) -lcurses -ltermlib
nondsp.o: nondsp.c
$(CC) $(CFLAGS) -c nondsp.c
# This is a shell archive.
