OK PMario, thanks for the information.
By the way, the 'plusminus' was just an example.
In another envornment (dokuwiki) I used markdown for automatic text to html
processing.
Then I used javascript to extend functionalities. Reference to js modules
in dokuwiki could be placed in the template, so to be accessible from all
articles.
So I could use dom to retrieve elements, attributes, classes, etc. and to
perform other useful replacements.
For instance, I could replace §{#id .'myclass' ... inline html code ... }§
with <span class='myclass' id='id'> inline html code </span>. So the
dictionary elements were not just math symbols, but replacement for html
code. Moreover, I use mathjax because allows inline math ${...}$ while it
seems not available in katex...
Or I could create automatically bidirectional footnotes, based on links
with special classes.
I could do this because the js code was kept in the final rendered code and
executed by the browser.
Therefore I thought to use js macro in tiddlywiki, but how to reference the
code in all tiddlers without calling it explicitly from each one?
Maybe there's another way to do the same...
Thanks and regards
Paul Netsaver,
Rome, IT
