The WikiBibtex extension was developed by Victoria Gitman. It is a modified combination of two pre-existing extensions: Biblio, written by Martin Jambon and others and Bibtex, written by Jean-Yves Didier and Kinh Tieu. Most of the code comes from these two original extensions. The chief modifications to the Biblio class consist of removing non-bibtex processing code, updating it to comply with new MediaWiki standards, and adding error catching mechanisms (e.g., when there is no entry for a cited key). Minor modifications to the Bibtex class consist of improving author name parsing, adding the ability to parse math in titles, adding the ability to process brackets in title and author fields. A major modification is that the bibtex code no longer appears in a pop-up but below the bibliographical item.

Brief instructions are given here. For more info, see http://boolesrings.org/victoriagitman/2014/06/06/a-wikibibtex-extension-for-mediawiki

To activate the extension, you have to:

1. Place files in the extensions/WikiBibtex subdirectory of your MediaWiki installation.

2. Update your LocalSettings.php file with this line:

require_once( "$IP/extensions/WikiBibtex/WikiBibtex.php" );

This module provides tags <cite> and <biblio>. <cite> tags indicate a citation in the text, one or several keys, separated by a comma, are given. These keys must be defined in the section. The <biblio> sections on the page and must come after the last citation. The <biblio> tag can contain either the bibtex entry itself or a link to an interwiki 'database' page containing bibtex entries. A bibtex 'database' page is trying to simulate a bibtex file, and it is linked using the syntax @[[database]] within the <biblio> tag. It must contain only bibtex entries (and HTML comments).

The tag <biblio> accepts the following options:

• force (default: false): The default is to display only cited items. Set this option to true to display all the items in the database.
• prefix (default: empty): Adds a prefix to the index of each entry. Useful when more than <biblio> tag is present in a single wiki page.

The tag <cite> accepts the following option:

• prefix (default: empty): Adds a prefix to the index of each entry. Useful when more than <biblio> tag is present in a single wiki page. The prefix in each cite must match the prefix in the corresponding <biblio> tag.
