I've just done the first release of wyvern [1], a small program to play moves for you on the Dragon Go Server [2], along with point releases for two supporting libraries. On DGS, people play many games of go simultaneously, making only one move per day in each game (about). A commonly requested feature is the ability to specify several moves in advance, and have them be played automatically whenever the opponent logs in. Wyvern provides this capability, as well as the ability to program in advance several "branches" -- conditional on the opponent's move. Along with wyvern, I've been developing two supplementary libraries. The "dgs" library [3] is a very small wrapper around DGS' handy robot interface. The "sgf" library [4] is a parser for the SGF file format (used to store games of go) that strives to balance using the type system to enforce the construction of correct SGF trees against conveniently manipulating said trees. It was also something of an experiment for me in documentation writing -- I may have gone a little overboard. =) If, like me, you love to mix Haskell and go, I invite you to check out one or more of these and let me know what you think. ~d [1] http://dmwit.com/wyvern [2] http://www.dragongoserver.net/ [3] http://hackage.haskell.org/package/dgs [4] http://hackage.haskell.org/package/sgf
