Raw Normal View History

Beginning of implementation of a ctypes-based interface to libboard, which is a much cleaner set of Go routines than I hacked together originally. Including a copy of gnugo 3.8 so we can build a dynamic version of libboard.

# The Owl urgent offensive pattern database. These are patterns
# which are always matched. The patterns in owl_attackpats.db
# are not matched if owl_shapes finds that the dragon has two
# eyes. So the patterns in this database are exceptional ones
# corresponding to defects in the optical code.
#
# Further documentation may be found in the Texinfo documentation.
#
# First there is a pattern title of the form: Pattern [string]. The
# string is used for identifying the pattern while tuning or debugging.
#
# Then a block of the following characters representing the pattern
# itself.
#
# ? : don't care
# . : empty
# X : your piece,
# O : my piece,
# x : your piece or empty
# o : my piece or empty
# * : my next move
# ! : your defense move against * (if different)
# -, | : edge of board
# + : corner of board
#
# If a pattern must not match at the edge of the board,
# an extra row of ?'s in the pattern may be added. (This
# will not add to the time taken to check the pattern.)
#
#################
#
# In the second field (classification) the following pattern attributes
# are possible. Friendly stones are 'O', opponent stones are 'X'.
#
# s : "Sacrifice" pattern. Omit the usual check that an O stone here
# cannot be capture.
#
# n : In addition to usual check that an O stone here cannot be
# captured, check also that an X move cannot be captured.
