Overview

Fons van der Plas introduces Pluto.jl, a reactive notebook for Julia that tracks references between cells and re-runs affected cells when code changes. The talk was given at JuliaCon 2020.

On Hacker News

HN recommends it as an enthusiastic demo of spreadsheet-like reactive notebooks, which commenters think new notebook projects should copy.

I think notebooks are great for building a presentation / reports of a data exploration, but I agree that they shouldn't represent programs. Rstudio won't export an R-markdown notebook to PDF without rerunning all cells sequentially. It's great for keeping the code "in check", but for things that takes hours to run, it can be quite annoying. I do think most of the problems with notebooks go away if you somehow force sequential running before presenting it to other people. Another really cool take on notebooks are Julia's Pluto Notebooks. Like a spreadsheet, there is no sequence that cells are run in. Everything is updated simultaneously. It's kinda hard to explain, but the JuliacCn presentation on these is absolutely wonderful: [VIDEO]

I think every new notebook project should take ideas from Julia's Pluto: [VIDEO] Working directly with the source files is just one of the niceties it has.

It is linked in the article, but I would like to draw attention to the wonderful JuliaCon talk presenting Pluto: [VIDEO]
