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 ²³⁵_{92₃²⁺; 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'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 element. (-> superscript)
*Put on _ before atomic number within a element. (-> subscript)

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

SS 2015-12-13: Doesn't work all that well. A simple formula of calcium carbonate CaCO3 shows as CaCo3 (lower case oxygen)

This tool is simply great! Love it:) Just a small suggestion, can we have a button in the toolbar in forum posts? I mean a small button in the toolbar with italic/bold. just like what this [[plugin:highlight]]tool has --- [[user>EpsilonC|EpsilonC]] //2017/10/06 10:24//
