This DokuWiki plugin formats a molecular formula easily.
Appearance | C2H5O2-Na+ |
---|---|
Without the plugin | C<sub>2</sub>H<sub>5</sub>O<sub>2</sub><sup>-</sup>Na<sup>+</sup> |
Using Chem plugin | <chem>C2H5O2-Na+</chem> |
The latest version supports to export Open Document format using ODT plugin.
Examples
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>
another Version
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 <html>23592<sub>32+</html>; 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)
