PGN-Extract: Portable Game Notation (PGN) Manipulator for Chess Games
by David J. Barnes

Introduction

This directory contains the C source code and win32 binary for version 16.7 of the pgn-extract program. This is a command-line program for manipulating chess games recorded in the Portable Game Notation (PGN). This program is made available under the terms of the GNU General Public License.

Overview

These are the C sources and win32 binary for a program to extract selected games from a PGN format data file. There are several ways to specify the criteria on which to extract: for instance, textual move sequences, the position reached after a sequence of moves, information in the tag fields, and material balance in the ending. The program includes a semantic analyser which will report errors in game scores and it is also able to detect duplicate games found in its input files.

The range of input move formats accepted is fairly wide and includes recognition of lower-case piece letters for English and upper-case piece letters for Dutch and German. The output is normally in English Standard Algebraic Notation (SAN), but this can be varied.

Extracted games may be written out either including or excluding comments, NAGs, variations, move numbers, tags and/or results. Games may be given ECO classifications derived from the accompanying file eco.pgn, or a customised version provided by the user.

A full description of pgn-extract's functionality is available and included with the sources.

Use the -h and (unnecessarily cryptic) -h1 (h one) argument to the program to get the full lists of arguments. (This will be improved in a future version.)
