I have a SGF parser in Java in my library. I haven't updated it in a while. You can find the SGF package here:

https://tesujigoframework.dev.java.net/source/browse/ tesujigoframework/TesujiGoFramework/source/tesuji/games/sgf/


I think it's pretty efficient and easy to use. For examples look at:

https://tesujigoframework.dev.java.net/source/browse/ tesujigoframework/TesujiGoFramework/source/tesuji/games/go/test/ SGFUnitTest.java

It has examples how to parse from a string, a file or how to iterate over a large game-collection without keeping everything in memory. There's also stuff there to make SGF out of a tree again and more such things.

Let me know if it's any use, so far I haven't seen much interest in this library. It seems everybody prefers to write their own standard stuff.

I'm looking for a nice Java SGF library that allows you to parse SGF files into a simple tree, and to serialize your own tree back to SGF. I've looked at a few of the open source Go projects currently out there, and I've searched the computer-go archives (and even found a post from myself a few years back on the subject), but haven't found anything that seems very robust.

So, my question here is twofold:
1) Does anybody know of a good Java SGF parser out there?
2) What would your criteria be for a good SGF parser? (e.g. it's more important that it's fast than memory-efficient, or vice-versa, or have a certain API, or allow for traversing the game tree without holding the entire file in memory, etc.)

If I can't find a good one out there, I may write one myself, probably based on JavaCC/SableCC, which I'm somewhat familiar with.

Thanks in advance for any feedback,
