Ocasional errors when yeeting text into Julia REPL

[aris-mav]

Hey there!

I've been noticing for quite a while that the Julia REPL throws some weird error every now and then when yeeting text into it:

julia> K = Diagonal(ones(2))
2×2 Diagonal{Float64, Vector{Float64}}:
 1.0   ⋅
  ⋅   1.0

julia> K = Diagonal(ones(2))

As shown above, I just yote K = Diagonal(ones(2)) several times into it, but once I got this BoundsError.
I've only ever seen that while using yeet.

The command is still evaluated whether the error appears or not.

Pretty sure this started happening in one of the relatively recent versions of Julia, but I do not know which one exactly.

Any ideas?

I have noticed the same with some specific projects, which I think might relate to the python version being used and how it's repl handles whitespace. Do you use tmux or just nvim terminal?

[aris-mav]

I've only used tmux so far, should I maybe try and reproduce with nvim splits?
