pgn-parser's Introduction

pgn-parser

Parse PGN files into a JS data structure (and syntax validation on the PGN)

Usage

From the command line: src/pgn-parser.js some/pgn/file.pgn

From js

const pgnParser = require('pgn-parser');

const [result] = pgnParser.parse('[White "me"]\n[Black "you"]\n1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 (3. ...Nf6 {is the two knights}) 4. b4 Bxb4 5. c3 Ba5 6. d4 exd4 7. O-O Nge7 $1 *');

console.log(result);

Output

The result parsing the PGN above would be

[
    {
        headers: [ 
            {name: "White", value: "me"},
            {name: "Black", value: "you"}
        ],
        result: "*",
        moves: [
            { move: 'e4', move_number: 1},
            { move: 'e5',
            { move: 'Nf3', move_number: 2},
            { move: 'Nc6'},
            { move: 'Bc4', move_number: 3},
            { move: 'Bc5', ravs: [{ moves: [{move_number: 3, move: "...Nf6", comments: [{text: "is the two knights"}]}]}]},
            { move: 'b4', move_number: 4},
            { move: 'Bxb4'},
            { move: 'c3', move_number: 5},
            { move: 'Ba5'},
            { move: 'd4', move_number: 6},
            { move: 'exd4'},
            { move: 'O-O', move_number: 7},
            { move: 'Nge7', nags: ["$1"]}
        ]
    }
]

pgn-parser's Issues

Doesn't handle pgn's with null moves

Some pgn's have null moves tabulated with --, quite a few available at The Week in Chess (https://theweekinchess.com/).

Example:

1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Nxd4 Nf6 5. Nc3 Bb4 6. Nxc6 bxc6 7. Bd3 d5 8.
O-O Bxc3 9. bxc3 dxe4 10. Qe2 O-O 11. Bxe4 Re8 12. f3 Bf5 13. Bg5 -- 14. Rad1
Qe7 15. Bxf6 Qxf6 16. Qc4 Rad8 17. Bxc6 1/2-1/2

Handle single line comments

Single line comments start with a ; character and go to the end of the line

Add typescript declaration to DefinitelyTyped repo

I've created a pull request to add typescript declarations to the DefinitelyTyped repo. Let me know if you see anything wrong with the type declaration. Thanks!

Parse fails on pgn from chess.com that includes computer analysis due to ±, ∓, and = characters

The chess.com analysis tool puts ±, ∓, and = characters into its pgn text when computer analysis is included. These characters are not contained within move comments. This causes parsing to fail.

Below is example pgn text from chess.com. Note the ± character in move 8:

1. e4 d5 2. exd5 Qxd5 3. Nc3 Qa5 4. Nf3 Nf6 5. Bc4 e6 6. d3 Bb4 7. Bd2 O-O 8. a3
Bd6? ± {MISTAKE (+3.05) Critical mistake.} ({(+1.06) The best move was} 8...
Bxc3 9. Bxc3 Qf5 *

I'm not sure if this usage of the ±, ∓, and = characters is normal in pgn, but I think it would be good for this package to be able to handle all chess.com pgn strings.

I'm happy to work on a pull request to fix this, but I'm not sure how those characters should be handled. Any opinions on that? Maybe the character should be prepended to the comment that follows it?

%cal and %cls not parsed

Hi,

nice library! Unfortunately %cal and %cls (arrows and square highlighting on the chess board) information is currently not parsed and creates an error.

Example (from https://lichess.org/study/D6DfYHZe):

{ [%csl Gf3,Gc6][%cal Gd2d4] }
1. e4 { this is a comment } { [%csl Gd5,Gf5][%cal Ge4d5,Ge4f5] } *

Also could you add a license to the project so others (like me :) ) could use it?

Accented characters are ignored in comments

The parser ignores comments with accented characters.

Example pgn:

[Event ""]
[Site ""]
[Date "????.??.??"]
[Round ""]
[White ""]
[Black ""]
[Result "*"]

1.e4 e5 2.f4 {A à E é I î O ô U ù Y} *

The comment is parsed as A E I O U Y.

there are correct pgns that it is not parsed correctly (with errors)

I have tried to parse this pgn :

but it's thrown this error:
Expected " ", """, "\r", "\t", or "\x0C" but "\n" found.

Possible to go back to pgn file format from JS structure?

I want to send a PGN game across the wire in json format. I then want to parse the json and transform it back to its original PGN file format. Is this possible with this library?

Current build is shown as failing - the build is also failing on my local setup?

Pawn promotion handling

Pawn promotion(for example c8Q) doesn't work now.

peg$SyntaxError: Expected " ", "!!", "!", "!?", "#", "+", "=", "?!", "?", "??", "\n", "\r", "\t", or "\x0C" but "Q" found.

Does not parse PGN with moves that have both rank and file

Consider the following game
https://www.chess.com/live/game/4610358993

Move 49 is Qg8f7because both rank and file are needed to disambiguate the move. So this is a valid pgn but while parsing we get the error:
Expected " ", "!!", "!", "!?", "#", "+", "?!", "?", "??", "\n", "\t", or "\x0C" but "f" found.

Full PGN is
