I had to do this for matlab. It isn't difficult but I remember there being some annoying syntax thing that came up somewhere. I didn't run into it while testing so maybe it won't be a problem.
Go to the download page here (https://highlightjs.org/download/) select the languages you want included in the plugin. Click the download button. In the downloaded zip file open up the file highlight.pack.js In the tiddler $:/plugins/tiddlywiki/highlight/highlight.js You want to replace everything between the first line var hljs = require("$:/plugins/tiddlywiki/highlight/highlight.js"); and the last line exports.hljs = hljs; with the contents of highlight.pack.js Then same the tiddler and reload your wiki. I didn't get an error doing it just now but I haven't tested it much. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
