I would like to request the addition of the two extensions in the directory Chemical (spec.
ChemFunctions.php, SpecialChemicalsources.php and the additional language file ChemFunctions.i18n.php)
to the wikipedia server (the files reside in
http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/Chemistry/). Could these extensions be
applied in the test wikipedia, and later (if they behave correcly) on the wikipedia? The programme has
been reviewed by Jimmy Collins, and he helped me to remove some errors in my programming.
Why do we want this patch: Within the Wikiproject:Chemicals (and the higher Wikiproject:Chemistry) one
of the issues has for long been the addition of external links to the pages about specific chemical
substances. The extension SpecialChemicalsources adds a special page which loads a special-page like
the special:booksources, but then for chemical identifiers. The extension in ChemFunctions adds the
functionality of a tag for the chemical formulae (which are now a hassle to put into a document), and
additionally links this to the special:Chemicalsources. The addition of the Specialpage should enable
us to remove many (biased) external links, especially those to commercial suppliers.
Installation: copy the three files to the extensions folder, and add lines to localsettings.php:
require_once( "$IP/extensions/ChemFunctions.php" );
require_once( "$IP/extensions/SpecialChemicalsources.php" );
(removing these two lines should disable the functionality again).
