Full KaTeX support

[Rafael Gonzalez]

I saw in the KaTeX plugin install tutorial that some fonts are not available. Also, I saw that some functions are not available (such as the \nabla operator). Is that because of the missing fonts or because the new KaTeX plugin. I really love TW5 it's a pitty that there is no ful LaTeX support.

Hi Rafael

I've just committed an upgrade to the latest version v0.2.0 of KaTeX:

https://github.com/Khan/KaTeX/releases/tag/v0.2.0

https://github.com/Jermolene/TiddlyWiki5/commit/ae001a19e5b3e43cf5388fd4e8d99788085649fe

As you can see, one of the improvements is that \nabla is now supported.

The upgrade will appear as part of TiddlyWiki 5.1.8 in the next week or so,

Best wishes

Jeremy.

I started the coursera quantum mechanics class (quite a challenge for me) and today I decided to use TW to take some notes, but I quickly found myself in similar situation desribed by Rafael: quite a few important symbols are unrecognized by current katex plugin (for example, I need \hbar in formulas but this gives error).

Based on the newer katex plugin in Jeremy's github, I've got things to now work by replacing the $:/plugins/tiddlywiki/katex/katex.min.js tiddler with
https://raw.githubusercontent.com/Jermolene/TiddlyWiki5/ae001a19e5b3e43cf5388fd4e8d99788085649fe/plugins/tiddlywiki/katex/files/katex.min.js and the $:/plugins/tiddlywiki/katex/katex.min.css tiddler with https://raw.githubusercontent.com/Jermolene/TiddlyWiki5/ae001a19e5b3e43cf5388fd4e8d99788085649fe/plugins/tiddlywiki/katex/files/katex.min.css

I just ignored the warning about editing shadow tiddlers, did the above replacement, saved the tiddlywiki, and the new symbols seems to work after reloading the wiki. I though I'd share as this hack manages to get me going now while I'll be waiting for the upcoming release.
