This site is a great resource on chess database utilities, most of which operate on pgn. In fact I use pgn-extract and Palview together to generate content for this blog, but this is worth another post. Palview is great for generating html with javascript for replaying games.
pgn-extract is a great command line tool for filtering pgn games for material, position, or tag information (e.g. It is also trivial to merge multiple PGN files into one via a one line in DOS.ģ) A lot of free command line and GUI PGN tools are already available. If you store your personal games in PGN, you can version control them as well, and look at the differences between revisions. Pgn is also very readable - the moves are just in algebraic notation. That being said, I suggest you do not write your own parser, because it is not a trivial task, but rather take an existing one (of course as long as license is not an issue).Ģ) since PGN is text-based - one can just load them in notepad, as long as the file size is not prohibitively large. There are few parsers available in source code (I managed to find c++, C# and perl parsers, there are probably others). So what are the advantages pgn format versus say, chessbase?ġ) it is free to in the sense that you don't need a proprietary software to view its contents (SCID would do the job), has an open spec, so 'anybody' can implement a parser. Chessbase does not handle Chess Assistant at all, Chess Assistant allows you to read Chessbase format, which is pretty impressive, given that no other non-chessbase tool does that. So what tools are available for dealing with each format? Virtually every chess tool can read pgn. At least most chess games available on the net are still available only in either PGN, Chessbase, or CA formats. There have also been a few efforts to represent chess databases in some open XML format, but of all schemas proposed, none has really gained enough popularity. Most other chess databases, such as SCID, Jose, etc also have their own binary formats, but I am not as familiar with those. There are at least popular 3 file formats I can think of - Chessbase (CB) binary format (cbh, cbv, etc), Chess Assistant (CA) binary format, and standard text pgn format (with the spec here). In what format do you store your chess data? This question has plagued me for years, so I finally decided to blurb it all out.
