How can I create a tiddler from Julia within MultiWikis.jl, add it to the archivo90_harold tiddlers file, and export it to the repository so that it can then be committed?

I encourage you to find and ask more concrete questions — ideally with code that demonstrates where you are stuck. See this topic for more guidance on what makes for a good “help me” sort of question here:
