Logseq Chess

A Logseq plugin for rendering chessboards

🛠 In development

Usage

Chess Positions

Create a chess fenced code block in your document and supply the positions with fen property:

```chess
fen: rnbqkbnr/pppp1ppp/8/4p2Q/4P3/8/PPPP1PPP/RNB1KBNR b KQkq - 1 2
```

You can also draw some arrows on the board, mark some squares and highlight the last move:

```chess
fen: r1bqkbnr/pppp1ppp/2n5/1B2p3/4P3/5N2/PPPP1PPP/RNBQK2R w KQkq - 0 1
arrows: f3->e5 b5->c6
squares: g5 f7
lastMove: f1 b5
```

Properties

You can set various properties inside the code block, each one on a separate line in the format name: value.

Property	Description	Possible values	Default
fen	Chess position	Any valid FEN string	Initial chess position
arrows	Series of arrows to draw	e2->e4 d2->d4	Empty
squares	Series of squares to mark	e5 d5	Empty
lastMove	Highlight last move	e2 e4	Undefined
size	Board width/height size in pixels or percents	400, 50%	280 pixels, overridable in plugin settings
orientation	Which side should be at the bottom of the board	white / black	white
showToolbar	Enables toolbar with orientation change control	true / false	false

Chess Moves

If you supply start position and moves property to the chess code block, it will become a move browser instead of static chessboard render.

In this case arrows and squares will be applied only to the starting position. And toolbar will be always visible, ignoring showToolbar value.

``` chess
fen: r1bqkbnr/1ppp1ppp/p1n5/1B2p3/4P3/5N2/PPPP1PPP/RNBQK2R w KQkq - 0 4
moves: Ba4 Nf6 O-O b5 Bb3 Be7 Re1 d6
arrows: f3->e5 b5->c6
lastMove: f1 b5
startFrom: last
```

Properties

Property	Description	Possible values	Default
fen	Initial position for the chain of moves	Any valid FEN string	Initial chess position
moves	The chain of valid moves	Ba4 Nf6 O-O	Empty
startFrom	Number of the move that should be set as current on initial render	1, 3, first, last	Empty
arrows	Series of arrows to draw on the initial position	e2->e4 d2->d4	Empty
