\rules is pretty poorly documented, but here's the best I can give you <https://tiddlywiki.com/#Pragma:Pragma%20%24%3A%2Fcore%2Fui%2FControlPanel%2FParsing%20%24%3A%2Fcore%2Fmodules%2Fparsers%2Fwikiparser%2Frules%2Frules.js>. That's what documenation exists, the list of rules, and the relevant source.
I glanced at katex, and the wikirule's name is "latex-parser", so just add that to the end of the renderWikTextPragma string. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
