mdconv VS remark

Eh there are loads of these based on Markdown that are much better. I think revealjs is the most popular, but I like remarkjs:

There's a list of them here:

Thanks for your comment, u/legitEngin. Indeed, I do see a slew of Markdown-to-presentation plugins (this work was inspired by one at https://github.com/gnab/remark), and I hope I can inspire more instructors to consider using plain text to organize their work instead of lugging around heavy PPTs.

remarkjs github; easy guide; simple demo with default settings

One of my proudest open source contributions is also to excalidraw. It's a small tweak. Since about a year ago, chrome will re-save the .png to disk when you ctrl+s or cmd+s (with the embedded scene, and without prompting for a location). It gives you a really nice workflow for documentation and remark-style slides for presentations.

just some text, but easy to tweak/adopt/write? -> https://remarkjs.com

It's a good idea, which is why it's already been done. That's not to say you shouldn't finish it! You might improve on the idea, or it might just be a good learning experience.

I've given presentations in ReMark before, which is basically "markdown -> web slideshow" using a JS blob. Worked alright for simple presentations without complicated formatting needs, and loads all the images on the fly, so it implicitly picks up any re-generated figures. It also made it very easily to collaborate on presentations via GitHub, since the whole "presentation" was a short text file.
