Brief Documentation:
Today I finished the move parsing in my ChessMove class!
ChessMove – A pydantic BaseModel I use to parse algebraic notation for chess moves into information I can use/store.
- I'm not entirely sure how useful this will be, but I know I will need it to some degree.
- Searches chess notation moves for the move number, the piece, square, check/mate, ...
- Init function just accepts the move notation and the color that moved
- Allows my board abstraction in
ChessGameto interface with the notation
The actual init function for this class is complete. It accepts the chess notation for the move, and the color that moved. As a result, it completely fills out my pydantic model with a ton of data about the move that I should be able to use for move validation, board manipulation, etc. Basically, I have a chess language that both the computer and humans can understand.
