Idea for richer notebook format

[j-fu]

Hi, just a thought here for a possible modificatioon of the notebook format -- in case you are considering to extend the current format with more stored information:

I can imagine to use a special comment prefix and some standard way to store richer config information - Julia or (preferably) toml which you can parse to dicts using TOML.jl E.g. like this:

#═╡ [PlutoNotebook]
#═╡ format_version = "2.0"
#═╡ pluto_version  = "1.20"



#═╡ [PlutoCell]
#═╡ uuid = "7f904dfe-b85e-4ff6-b463-dae2292396a8"
#═╡ hidden = false
#═╡ show_output=true
#═╡ results_on_top=false
hack hack hack

#═╡ [CellOrder]
#═╡ order = [ 
#═╡	      "uuid1",
#═╡	      "uuid2"
#═╡	   ]

(not sure if the Julia toml parser supports arrays).

This would give you the possibility to add richer meta information to the notebook in an extendable way.

Edit: this could be consistent also with some of the ideas in e.g. #142 .:

#═╡ [PlutoProject] 
#═╡   project.toml stuff here
#═╡

Edit: I think an API for reading and writing notebooks could go into an extra package, thus allowing tools
like Literate to write notebooks through this API and encourage the development of a large tooling ecosystem.

Thanks!

(I'll point out that you can use ; as the last character of a cell to toggle showing output.)

I've put this on the notion page:

... I had in mind the @with_output stuff, also with regard to https://julialang.zulipchat.com/#narrow/stream/243342-pluto.2Ejl/topic/print.20inside.20in.20the.20notebook.3F/near/209725305 Best regards Jürgen

For cell metadata, this is implemented in #1895
