Hi
Just to inform you for new GnuGo Java
porting project. It is just changed for jdk1.5 to handle enums. Project started from GnuGo 3.4 and most 3.6 changes are
added (thanks for good change logs).
Core Gnugos engine and
pattern logic are target for porting. Ported Java code has
currently 75 Java classes from small
structs like "aa_move" to big classes like Owl. It has been such state that it compiles now about half year, but it is
far from working state, there is lot more things which don't work than which
work.
Biggest problem has been c pointer logic used in
GNU-go. Also other c constructs(like function pointers, macros, global name
space) where tough but are little easier to handle than pointers ( ok problem is
not one pointer function but there is so many pointer functions). I
think pointer logic really does not give anymore much benefits in c++?
So please avoid it :) propably has no effects, but
tried :))
There is some developer reasons for porting(there
is other more subjective reasons also):
Javas collections framework and
OO code makes code clearer than orginal.
Computers change faster and base
speed is not so important anymore(actually it is easier to code very advanced
data structures using java and
so on results can be sometimes even better) Most of data structures are change dynamic
size for example.
XML makes input output
implementations simpler and cooler :). XML is used file format. There is converter to convert GnuGo
patterns for XML. XML is used also in game
format instead of SGF(and converter still misses
branches). Out of porting or don't work:
Pattern reading and usage don't work
yet.
Caches role are unclear or are out of porting like
this new persistent cache.
all parts not belong AI are out of
porting.
testing procedures are not ported(quite much
work there)
features marked as #if 0 are out
..
If there is some intrest in GnuGo community for those XML things or porting
details I send more info. So far porting has been advancing faster than new
code is added gnugo I think. t. Harri
