Hi all, I made a video that at first sight is about a way to use REPLs to explore TikZ - and TikZ is a huge (La)TeX package for drawing graphics...<p>At second sight that video is about a series of tricks for using REPLs in Emacs, and TikZ is just an excuse to present them. As far as I know those tricks are very unusual; they implement a kind of "meta-REPL" that controls other REPLs, and they do that in a way that is much simpler, and much easier to hack, than Org's code blocks and than the cells in Jupyter notebooks.<p>The page has lots of screenshots and links, and it has instructions for downloading the video and its subtitles, and for reading the subtitles in plain text. I tried to make everything as accessible as possible for the people who just want to watch the the first two parts of the video - "Introduction" and "Trying it" - in super-high speed.<p>I'm especially interested in pointers to related work. Cheers, have fun, etc! =)
