A Logseq plugin for rendering chessboards
🛠 In development
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
```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 |
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.
