[pbmserv-dev] Adding a command to a game

[Robert Barrell <games@rdbhn.org>]

Hello.

For my first foray into PBM-related development, I would like to add an 
SGF function to Go.  I have a test server set up, and have the code 
almost done, but I am used to using C, AWK, Shell, etc., and not C++, so 
I have not yet figured out how to get it to work from the go.cpp module 
(at this point, it is working fine within game.cpp).  Ideally, since the 
SGF format also supports other games, the best approach would be to:

* Add an "sgf" comnmand to game.cpp and have it call the SGF function of 
the game for which it is being run.
* Add the functioning SGF function to go.cpp for use now.
* Add SGF functions to the code for existing games, but have them return 
a "failure" status so that game.cpp could say "The 'sgf' command is not 
implemented for game %s" but also allow future SGF programmers to add 
SGF to other games without having to modify game.cpp or game.h (they 
would only need to have their SGF function return a "success" status).

Unfortunately, after trying several different things, I have not been 
able to figure out how to make the function a member of the Go class, 
then have it called from the command-parsing section of game.cpp.

Any ideas?

Thanks!
