We'll create fresh WordPress site with PgnViewerJS installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Integration of PgnViewerJS into WordPress. This is a small layer around the original PgnViewerJS, but is needed to use it in a WordPress installation. At the end, it should provide the following interfaces:
[pgnv]1. e4 e5 2. ...[/pgnv]
This is the PgnViewer (mostly needed): allows to play through a game (including variations), printing the comments, NAGs, …
[pgne]1. e4 ...[/pgne]
Allows to edit and view a game. At the end, you may use the PGN button to display the notation, that then may be copied again in the WordPress post entry.
[pgnb fen=<a FEN string>][/pgnb]
Just to display a board (only), no moves.
[pgnp]1. e4 e5D 2. Nf3 Nc6D ...[/pgnp]
Allows to print a game in a format similar to magazines and books. For that purpose, the notation of PGN was expanded by the “D” at the end of a move, that stands for the diagram.
