A small rust crate that adds some minor conveniences on top of rust-pgn-reader together with rayon to process in parallel a directory of compressed or uncompressed PGN files into CSVs.
To generate a new set of CSVs containing data to your specific requirements, you write a binary file whose main() function calls pgn2csv::pgn2csv::<P>(), where P is a type that you create that implements the traits Default, pgn_reader::Visitor, and pgn2csv::GameProcessor. GameProcessor has two methods, skip() and row(), that respectively define whether a specific game's data is relevant to you and should be included as a row in the csv, and what data that row should hold. The latter should return a type that implements Default and serde::Serialize. There are a couple examples of usage in src/bin.
To use one of the existing binaries in src/bin, you must have Rust installed on your system. Then, from the root directory of this repository, run e.g.:
cargo run --release --bin time-odds path/to/pgns path/to/csvs
where time-odds can be replaced with the name of any of the binaries in src/bin. This will convert .pgn, .pgn.bz2, or .pgn.zst files in directory path/to/pgns to .csv files in directory path/to/csvs. Running the command with just the first argument will write the CSVs to the same directory as the pgns. In either case, the CSVs will have the same name as the PGNs, but with the final extension replaced with .csv.
