Extension:Go diagrams

The Go diagrams extension may be used to edit and display go diagrams in MediaWiki. The output looks similar to the one on http://senseis.xmp.net but it's antialiased. SGF is also supported.

Features

 * SGF output
 * hyperlinks
 * different styles ("large", "normal", user-defined)
 * (optional) coordinate markers
 * anti-aliased output

Download

 * 10:03, 2 April 2006 (UTC) version 0.8: /godiag.php

Requirements

 * PHP + GD2 and FreeType
 * MediaWiki 1.6 or 1.5
 * License: GPL

Installation & config

 * 1) Create a directory for godiag and make it writeable by the web server and accessible via HTTP.
 * 2) Copy the file to MediaWiki's extensions directory.
 * 3) Add the following to your LocalSettings.php:

require_once('extensions/godiag.php'); $wgGodiagDirectory = "/sys/path/to/dir";       // e.g. "$IP/godiags" $wgGodiagPath = "/url/path/to/dir";        // e.g. "$wgScriptPath/godiags" $wgGodiagTTFont = "/path/to/truetypefont"; // e.g. "/usr/share/fonts/bitstream-vera/Vera.ttf"

MIME
Note: You may also specify an SGF mime type so your server presents the SGF's correctly to the client. This worked for me: printf "application/sgf\t\t\tsgf" >> /etc/mime.types (restart web server)

I18n
You'll need to set a few extra vars in LocalSettings.php, if you want to use the extension in non-English wikis:


 * &mdash; this is the format of hints about additional moves in the title (e.g. "8 at 1"). The default is:
 * ,, and

Example for Bulgarian:

require_once('extensions/godiag.php'); $wgGodiagDirectory = ...; $wgGodiagPath = ...; $wgGodiagTTFont = ...; $wgGodiagHintRegex='/(\d|10) (?:at|on|на|върху) (\d)/'; $wgGodiagSgfLinkText = ; // usually =  since an image is used $wgGodiagSgfLinkTitle = 'сваляне на SGF'; // "download SGF" $wgGodiagSgfComment = 'SGF diagrama ot RomanizedWikiName'; // ASCII(!) comment

Go diagram styles
Godiag comes with two predefined styles, "normal" and "large". You may specify the style for a diagram by starting it with

 $$#stylename title ...

(put any options like 'W' and 'c' or board size before the '#', like ).

You may define more styles, e.g. in LocalSettings.php:

$wgGodiagStyles['mystyle'] = array( /* ... */ ); // see source for two examples $wgGodiagDefaultStyle='mystyle';                // make it default

Syntax
The syntax is in most cases compatible with http://senseis.xmp.net/ but usually less strict. There are also a few extensions. In short:


 * put things between:

 $$ title

and




 * use these symbols:

- horizontal border . unoccupied point , hoshi point X    black O    white B    black circled W    white circled @    white with square C    circled point S    point with square 0-9  numbered moves (0=10); black is first by default a-z  marked points _    empty space (useful as separator and for other effects)
 * vertical border
 * 1)     black with square

 * place options after the initial '$$'
 * &mdash; black player makes move 1 (default)
 * &mdash; white player makes move 1
 * &mdash; insert a break after the image; The following text will appear below the image.
 * &mdash; draw coordinate markers
 * &mdash; float left
 * &mdash; float right (default)
 * – &mdash; specify board size (default is 19). Useful for sizes above 19 and as a hint to SGF.
 * Example:
 * you can add hyperlinks at the end, e.g.:
 * add "X at Y" hints to the SGF generator in the title, e.g. "A mysterious disappearance (9 at 3)" will create an SGF with moves 3 and 9 on the same spot.

Maintenance

 * Remove older files in godiag-dir/tmp (files used in previews, leftovers from failed generations)
 * If you want to recreate the SGF/PNG files, empty the png/sgf subdir and set  in LocalSettings.php to the current server time:.
