Crate sgf_parser

SGF Parser for Rust

A sgf parser for rust. Supports all SGF properties, and tree branching.

Using pest for the actual parsing part.

Example usage

use sgf_parser::*;

let sgf_source = "(;C[comment]EV[event]PB[black]PW[white];B[aa])";
let tree: Result<GameTree, SgfError> = parse(sgf_source);

let tree = tree.unwrap();
let unknown_nodes = tree.get_unknown_nodes();
assert_eq!(unknown_nodes.len(), 0);

let invalid_nodes = tree.get_invalid_nodes();
assert_eq!(invalid_nodes.len(), 0);

tree.iter().for_each(|node| {
  assert!(!node.tokens.is_empty());
});

let sgf_string: String = tree.into();
assert_eq!(sgf_source, sgf_string);

Structs

GameNode	A game node, containing a vector of tokens
GameTree	A game tree, containing it's nodes and possible variations following the last node
SgfError	SGF parsing, or traversal, related errors

Enums

Action
Color	Indicates what color the token is related to
DisplayNodes
Encoding
Game
Outcome
RuleSet	Provides the used rules for this game. Because there are many different rules, SGF requires mandatory names only for a small set of well known rule sets. Note: it's beyond the scope of this specification to give an exact specification of these rule sets. Mandatory names for Go (GM[1]): "AGA" (rules of the American Go Association) "GOE" (the Ing rules of Goe) "Japanese" (the Nihon-Kiin rule set) "NZ" (New Zealand rules)
SgfErrorKind	Describes what kind of error we're dealing with
SgfToken	Enum describing all possible SGF Properties

Functions

parse

Main entry point to the library. Parses an SGF string, and returns a GameTree.
