PGN parsing and writing #36

Is it something that could be part of this library ?

Btw thank you for this awesome lib! :)

niklasf commented 2 years ago

Thanks.

Yes, absolutely, PGN handling is definitely within the scope of this library. To help make some decisions about data structures, can you please describe what kind of operations you would be doing with parsed games?

Currently, I'm building a tree that looks like:

type Node = {
  ply: Ply
  fen: Fen
  san: San
  children: Node[]
}

Basically I would:

Walk the tree like in the lichess analysis, including variations
Search a set of games (repertoire) by position.

I've seen your work for python and this looks perfect. Let me know if I can help ;)

+1, a visitor interface like your python-chess would be fantastic

I finished a basic implementation. Still needs more testing, documentation, and maybe some convenience methods/functions ...
