pgnparse
Parse PGN to Rust struct ( headers as hash map, main line moves as san, uci, fen, epd records ) or to JSON. All lichess variants are supported. Custom starting position using FEN header is supported. Create a book of parsed pgns.
Usage
extern crate env_logger;
use pgnparse::parser::*;
use log::{info};
fn main(){
env_logger::init();
let pgn = r#"[FEN "8/8/8/8/8/7k/8/7K w - - 0 1"]
[White "White"]
[Black "Black"]
[Variant "Atomic"]

"#;
info!("parsing pgn");
let result = parse_pgn_to_rust_struct(pgn);
println!("rust struct = {:?}", result);
let result = parse_pgn_to_json_string(pgn);
println!("json = {}", result);
}
Advanced
extern crate env_logger;
use pgnparse::parser::*;
fn main(){
env_logger::init();
let mut book = Book::new().me("chesshyperbot");
book.parse("test.pgn");
let pos = book.positions.get("rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq -");
println!("pos for epd = {:?}", pos);
if let Some(pos) = pos {
let m = pos.get_random_weighted_by_plays();
println!("random weighted by plays = {:?} , plays = {}", m, m.unwrap().plays());
let m = pos.get_random_weighted_by_perf();
println!("random weighted by perf = {:?} , perf = {}", m, m.unwrap().perf());
let m = pos.get_random_mixed(50);
println!("random mixed = {:?}", m);
}
