package pgn_to_tex

Pgn to Tex

Install

• Install the Opam package with: opam install pgn_to_tex
• Reference pgn_to_tex in the libraries stanza in the relevant dune file

Usage

open Pgn_logic

let diagrams_json_stringified = {| [{"ply":1,"fen":"rnbqkbnr/pppppppp/8/8/3P4/8/PPP1PPPP/RNBQKBNR b KQkq - 0 1"},{"ply":2,"fen":"rnbqkbnr/ppp1pppp/8/3p4/3P4/8/PPP1PPPP/RNBQKBNR w KQkq - 0 2"}] |}
let diagram_data = Pgn2tex.parse_diagrams_json diagrams_json_stringified

let game_tex = Pgn2tex.to_tex pgn ~diagram_data ~clock:false

This will return a LaTex markdown representation of the PGN file along with chess board diagrams at the specified ply. Clock times can be rendered for both sides if you pass ~clock:true to the to_tex function.

Latex preample and document setup markdown is not included in the output. You will need to add something similar to below around the game_tex output to create a valid document:

\begin{document}
\begin{multicols}{2}
game_tex goes here
\end{multicols}
\end{document}

Compile a JavaScript version of the library

With the library installed, you can compile the code to JavaScript by running:

make build

This will generate the JavaScript file at _build/default/bin/main.bc.js

This JavaScript file is minified and in CJS format, working in both Node and in the browser.

A single function to_tex is exposed, accepting the same arguments as the main library.
