A simple PGN Parser with tools. MADE WITH PERL!
PGN Parser is a simple PGN parser made with Perl. It contains a set of tools to process the games in a PGN file.
- Just copy the perl script to your Linux computer.
- If you still somehow use Windows, you can get Linux Mint.
- If you insist in using Windows, well... you can install Strawberry Perl.
./pgnparser.pl COMMAND file [options]Just reads and silently plays the games, good for testing PGN file and benchmark.
Searchs a pattern in the game position. Upper/Lower case color applies. Think "short-circuit" evaluation, faster and/or lesser common positions go first for speed. In Windows, search pattern must go between double quotes.
- w Evaluate only white or black active move, before the actual move. Must go first.
- Qd1 White queen in 'd1'
- Qma4 White queen can move/capture to 'a4', valid move with free path.
- Qxd8 White queen can xcapture to 'd8', destination square must be with enemy piece.
- Qjh5 White queen can jump to 'h5', ignore other pieces in path.
- .a8 Any piece on 'a8' (To be done)
- !h8 No piece on 'h8' (To be done)
- K[Q,+1,+1] White king has black queen one square northeast. (To de done?)
Example for 'King Usurper', white king on black throne:
./pgnparser.pl search file.pgn "w Ke8"Example for 'Greek Gift Sacrifice', white turn:
./pgnparser.pl search file.pgn "w kg8 rf8 Bxh7 Nmg5 Qjh5"- Convert game to FEN.
- Convert game to images.
- Reformat file nice.
- Code optimization.
- Nice option parser.
- Make GIF of the game.
- Patterns with OR operator.
- Made in a week of coding sprint, around 40 hours (because pandemic).
