Pluto.jl: Vector(undef, 3) does not show

[fonsp]

but in the REPL

[fonsp]

Someone needs to figure out how Base Julia does it, i.e. go through what happens when you call

show(stdout, MIME"text/plain"(), Vector(undef, 3))

[shashankp]

displaying data does a loop, which is failing; MVE:

I see why Pluto errors, but why wonder why show(stdout, MIME"text/plain"(), Vector(undef, 3)) _does not error_.

[shashankp]

works fine cos it goes to base implementation which has checks for isassigned & isdefined. As expected, works fine in REPL too

where as

goes to
show(io::IO, ::MIME"application/vnd.pluto.tree+xml", x::AbstractArray{<:Any, 1}) ref

May be it needs isassigned/isdefined checks?

[fonsp]

That sounds good!

[shashankp]

this should help with https://github.com/fonsp/Pluto.jl/issues/354 too

[fonsp]

No that's unrelated I think. missing is a valid Julia object, and Pluto can show [missing, missing] just fine

@fonsp fixed. issue was that we pass indices and x, so we no longer need to slice up x before passing.

Awesome, thanks!
