package pgn_to_tex

0.1.0

Breaking changes

• Renamed the public entry point from Pgn_logic / Pgn2tex to Pgn_to_tex. The old modules are removed with no compatibility aliases.
• Pgn_to_tex.to_tex takes optional ~diagram_data and ~clock arguments before the PGN string, and defaults to no diagrams and no clock output.
• Removed the internal parser, AST, LaTeX, and NAG modules from the public surface. diagram_data is now an abstract type.
• Renamed the optional JavaScript artifact from main.bc.js to pgn_to_tex_js.bc.js.

Added

• New public API: Pgn_to_tex.to_tex, Pgn_to_tex.parse_diagrams_json, Pgn_to_tex.empty_diagrams, and the abstract diagram_data type.
• Diagram JSON accepts path, ply, or both. Paths identify mainline and variation positions; path lookup takes precedence over the legacy ply fallback, and path-only variation entries are supported.
• Diagrams inside variations render inline at the smaller smallboard size.
• Generated odoc API documentation, a package landing page, and a GitHub Pages deployment workflow.
• GitHub Actions CI covering formatting, build, tests, docs, the JavaScript build, the Node smoke test, and opam lint.
• A self-contained README covering installation, the API, diagram JSON, clocks, variations, headers, NAGs, errors, the LaTeX preamble, and JavaScript usage.
• js_of_ocaml and js_of_ocaml-ppx are declared as test-only dependencies.

Fixed

• A mixed Author and player header no longer produces an empty author line.
• A Title without a Subtitle no longer emits an empty subtitle block.

Changed

• The package version is now 0.1.0.
• Documentation now points at https://therealowenrees.github.io/pgn_to_tex/.
• Removed stale CI-acceptance metadata for unsupported OCaml versions.

Migration from 0.0.x

Replace the old import and module prefix:

(* 0.0.x *)
open Pgn_logic

let diagrams = Pgn2tex.parse_diagrams_json json
let tex = Pgn2tex.to_tex pgn ~diagram_data:diagrams ~clock:false

(* 0.1.0 *)
let diagrams = Pgn_to_tex.parse_diagrams_json json
let tex = Pgn_to_tex.to_tex ~diagram_data:diagrams ~clock:false pgn

Use Pgn_to_tex.empty_diagrams when a game has no diagrams. Diagram data is now abstract, so replace any hand-built MoveMap.t with Pgn_to_tex.parse_diagrams_json. The JavaScript to_tex function keeps the same three arguments; only the artifact name changed.

0.0.2

• support diagrams in variations. Diagram data now carries an optional path (the SAN move sequence from the root) alongside the legacy ply; diagrams whose path resolves inside a variation are rendered inline within the variation. parse_diagrams_json returns a diagram_data record with by_ply and by_path maps.
• make variation board diagrams slightly smaller than mainline board diagrams

v0.0.1

• fix bug whereby a subtitle custom PGN header was rendering on a separate page. It now appears under the title
• remove old tests and commented out code

v0.0.1-rc.2

• add correct versioning metadata

v0.0.1-rc.1

• Update readme and add license file

v0.0.1-alpha.2

• Expose function parse_diagrams_json to convert stringified JSON to a MoveMap, allowing for parsing of the diagram data with to_tex

v0.0.1-alpha.1

• Initial release
