Extension:Chemistry/ChemFunctions.php

ChemFunctions.php contains some functions used for chemical identifiers:

chemform-tag

Chemical Formula in the wikipedia can be quite tedious to put into the text. By placing the plain formula (without sub/superscript) inbetween the chemform-tags results in a formula being formatted properly; all numericals in subscript, all charges in superscript (numericals before a + or a - are also put in superscript (see examples).

Usage

<chemform>H2O</chemform>

Options

link: the text between the tags will be a link to Special:Chemicalsources.

noprocess: the text between the tags will not be processed.

query: the link created will not generate the 'to-search-for' data from the text between the tags, but use the value of this field instead.

wikilink: the formula between the tags will be a wikilink to the page (not yet implemented).

Examples

1. <chemform>H2SO4</chemform> will appear as H₂SO₄
2. <chemform>HSO4-</chemform> will appear as HSO^4-, hence use:

<chemform>[HSO4]-</chemform> (result: [HSO₄]^-)

<chemform noprocess>HSO₄^-</chemform> (result: HSO₄^-)
