# React Chessboard Expandable This is a fork of the [react chessboard](https://www.npmjs.com/package/react-chessboard?activeTab=readme) project which supports an expandable chessboard. It supports a new fen, I have horribly named modified fen which supports this expandable chessboard requirement ## Modified FEN I have introduced a FEN string modification to support my requirement of an expanding board. ### Requirements - The board should be able to expand from the original 8x8 board 1 square at a time - Pieces should be able to occupy any of the newly created squares ### Solution Normal FEN looks like this ``` rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR ``` I have introduced a few new special characters | Character | Description | | --------- | ---------------------------------------------------------------------------------------------------------------------------------- | | # | This character should show up at the starting of the row defining the 8th rank | | $ | This character should show up before the character on the a file | | E | This character simply a non existent square. The purpose of this character is to disambiguate square with no piece and empty space | ### Examples #### Board with 1 row as the 9th rank ``` 8/#rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR ``` #### Board with 1 row as the 0th rank ``` #rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR/8 ``` #### Board with a file before the a file ``` #1$rnbqkbnr/1$pppppppp/1$8/1$8/1$8/1$8/1$PPPPPPPP/1$RNBQKBNR ``` #### Board with a file after the h file ``` #$rnbqkbnr1/$pppppppp1/$9/$9/$9/$9/$PPPPPPPP1/$RNBQKBNR1 ``` #### Board with a few squares added on top of 8th rank ``` 2EEEEE1/#rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR ``` #### Note I know its a horrible name, I should have named it something like expandFen or fenPlus, but I am too lazy to change all occurances of it in my code.
