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

```rust extern crate env_logger;

use pgnparse::parser::*;

fn main(){ let pgn = r#"[FEN "8/8/8/8/8/7k/8/7K w - - 0 1"] [White "White"] [Black "Black"] [Variant "Atomic"]

   let result = parsepgntoruststruct(pgn);

   println!("{:?}", result);

   let result = parsepgntojsonstring(pgn);

   println!("{}", result); } ```

Advanced

```rust extern crate env_logger;

use pgnparse::parser::*;

fn main(){ let mut book = Book::new();

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);
}

} ```
