I'm not trying to poo on the OP or Marp. I'm actually interested in using a project like these and would be keen to see some kind of "why x over y" section in the readme.
i really liked the live preview and the output to pdf.
i do prefer pdf over web-based presentations because they are easier to share without a webbrowser (just send a document) (and they can still be viewed in a browser).
most irritating was the fact that i could not use my preferred editor. i haven't checked all the recommendations here, but i'll be looking for a combination if something like markdown in vim with live preview in a browser or pdf viewer
I am using markdeck with vim. Markdeck has an auto-reload, that means, every time you save your markdown or change something in your assets-folder, the web view gets reloaded automatically; so not really live preview, but auto-reload on save...
And markdeck has a standalone-exporter: it generates a single html file with all resources embedded (url-data, base64, ...); one file to send/open/view, but with working animations and the like (even the terminal session works)
marp looks great, but I just tried to use it and the $size directive does nothing, there are no docs on how to write themes (which is the first thing I want to do, customize the layout) and generally looks underdocumented.
It's too bad, because these tools are fantastically useful, but it doesn't look like any one managed to gather enough adoption to get critical mass around it.
