The PgnJS extension displays and animates chess games (boards and moves). Chess games are simply given in PGN format in a <pgn> tag and displayed thanks to the powerful javascript engine PgnViewerJS. In fact most of the functionality is provided by PgnViewerJS. This extension only implements the parsing of the <pgn> tag.

Installation

edit

The simplest is to clone the git repository in folder extensions of your wiki and run the install target (for MW 1.25 or above) or install-1.24 (for MW 1.24 or older):

cd /path/to/your/wiki/extensions
git clone --recursive --depth 1 https://github.com/xeyownt/mwpgnjs PgnJS
cd PgnJS
make install             # For MW 1.25 or above
make install-1.24        # For MW 1.24 or older

Don't forget the --recursive option since the extension uses git submodules.

make install / make install-1.24 will delete all files that are not necessary for the extension to run, and add the following line at the end of LocalSettings.php:

// For MW 1.25 or above:
wfLoadExtension( 'PgnJS' );
// For MW 1.24 or older:
require_once "$IP/extensions/PgnJS/PgnJS.php";

  Done! Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
