How to use ?

Though I tried to make the app as self explanatory as I could, nothing replaces a good old readme ;)

This app is a simple text editor that will turn the FEN formulas you append in the text editor to actual chessboards pictures when you click on Export PDF 🖨

All the features from a usual text editor (font size, colors, layout...) are also available!

FEN, PGN, what are these?

Depending on your familiarity with chess on computers, you may already know these files.

A FEN (for Forsyth–Edwards Notation) string looks like this: rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1 It describes the state of the chessboard (with castling information and the player turn). However, it does not describe the sequence of moves that led to this position.

On the other hand a PGN (for Portable Game Notation) string looks like: 1. e4 e5 2. d4 exd4 3. Nf3
