What prompt is that? (Does the copy/paste works as with the standard Julia prompt?)

It’s basically like what IJulia does (I think inspired by IPython?), you get numbered promps and return values are stored in an `Out` dict, e.g. above I can do:
```julia
In [6]: Out[3]
5×5 Diagonal{Bool, Vector{Bool}}:
1 ⋅ ⋅ ⋅ ⋅
⋅ 1 ⋅ ⋅ ⋅
⋅ ⋅ 1 ⋅ ⋅
⋅ ⋅ ⋅ 1 ⋅
⋅ ⋅ ⋅ ⋅ 1
```
Don’t know about the copy/pasting, as I’m on Windows and afaik that never worked on the Windows terminals 🙂

_EDIT_ Yes. it does work I just tried.
~~No. I just tried.~~
But setting the prompt color fails. I imagine ~~these~~ this will be fixed for 1.10 (well there’s a chance if someone, maybe me opens an issue).
Another problem is that it looks nearly-exactly like the ipython prompt. So if you have terminals running both Julia and ipython it’s hard to tell at a glance what you are looking at. I tried setting the color some other way. I’m sure it’s possible. But clobbering the prompt function in my startup.jl as follows seems to work for distinguishing them. It replaces `"In"` with `"Julia"`.
```julia
using REPL
function REPL.Numbered.set_prompt(repl::REPL.LineEditREPL, n::Ref{Int})
julia_prompt = repl.interface.modes[1]
julia_prompt.prompt = function()
n[] = REPL.Numbered.repl_eval_counter(julia_prompt.hist)+1
string("Julia [", n[], "]: ")
# string(repl.prompt_color, "Julia [", n[], "]: ")
end
nothing
end
```
Note, I commented out the attempt at coloring the prompt. This is because the prompt length is measured incorrectly somewhere and this is used for positioning the cursor.
_EDIT_ The following is straight forward, see comments below.
Finally, I don’t know how to search discourse for talk about `numbered_prompt!`. ~~The underscore and bang symbol seem to be stripped. Or numbered\_prompt is interpreted as a search for posts with EITHER numbered OR prompt. Very 1996.~~

Have you tried `"numbered_prompt!"`? This will use match case search.

I think it should work — it does for me. In fact it’s tested:

Yes, I corrected my post. I was trying with OhMyREPL. It works sometimes with OhMyREPL, sometimes not, depending on what you have already entered. I haven’t been able to nail down what sequence of input causes it to begin failing.
This is not a problem, since OhMyREPL comes with the caveat that it will break things in unpredictable ways.

Yes, I tried that before writing my post and was sure that it did not work. But, now that I try it, it works perfectly. Ghosts in my machine today.
