This DokuWiki plugin formats a molecular formula easily.

The latest version supports to export Open Document format using ODT plugin.

C₂H₆

<chem>C2H6</chem>

Na₂HPO₄ 12H₂O

<chem>Na2HPO4 12H2O</chem>

C₂H₅O₂^-Na⁺

<chem>C2H5O2|-Na+</chem>    // | is a splitter.

Cl₂H₆N₂Pt²⁺

<chem>Cl2H6N2Pt2+</chem>

Al₂(SO₄)₃

<chem>Al2(SO4)3</chem>

The original plugin works very fine.

For those of you who have to write more chemical formulars and have some extra wishes like easier syntax, nuclid-number, and a nicer output in DokuWiki pages the following suggestion could help you.

Syntax:

92|235U3|2+

would appear as <sup>235</sup><sub>92<sub>3</sub><sup>2+</sup>; the single numbers are optional so expressions like U2+, U2, 235U or 92|235U are recognized as well as all the brackets.

Unfortunately there are some limitations:

• Due to many preg_matches the entering and leaving of DokuWiki editmenu takes quite long
• ODT-Support doesn't work - but that´s just due to a lack of regular expressions to get the formatting out. (May someone could give me a hand here)
• if you use ions and have multiple elements the shifting breaks as I just optimized it for one digit. (May someone could give me a hand here)

I'll work on it soon (in Apr, maybe — iobataya 2010/04/04 22:23

I'd like to apply a new syntax for notation of isotopes in order to simplify either the DW syntax and the regular expressions.

• Put on ^ before nucleons within a <chem> element. (→ superscript)
• Put on _ before atomic number within a <chem> element. (→ subscript)

#EXAMPLE
^14_6C        (carbon-14)
^235_92U      (uranium-235)
