It shows repeated output in VScode

[albertomercurio]

Hello,

if I try to run the following script, it shows a repeated output.

p = Progress(10)
for i in 1:10
    sleep(0.5)
    next!(p)
end

Hello, I have the same issue with the version 1.7.2.

[oschulz]

Just ran into this as well. :-)

[timholy]

I'd merge a PR that fixes it, if you care to submit one.

[oschulz]

No idea why this happens, but I can play around a bit.

There is an open issue about this in microsoft/vscode#200261. Apparently there was a similar bug in Python microsoft/vscode#146397.

Issue seems to be dependent on which kernel is selected. i.e. using a jupyter kernel (that loads IJulia) works. using the default kernel from the julia vscode extension doesn't.

some of this is from the CLEAR_IJULIA[] checking isdefined(Main, :IJulia) && Main.IJulia.inited

We can check if we are in the default vscode notebook context with:

# true if in vscode notebook
running_vscode_kernel() = isdefined(Main, :VSCodeServer) && !isinteractive() 

but I don't know of how to flush clear the output cell, when IJulia is not loaded

See #271

Has there been any update to this? A manual fix for now or an alternative? I am using the default vscode extension kernel.

[MarcMush]

an equivalent to IJulia.clear_output() would be needed (julia-vscode/julia-vscode#2473)

[oschulz]

How do Python VS-Code notebooks handle such things?

I can confirm this

I just released a new version of the extension that should improve the situation a bit. At least for simple one-line progress bar I think it should all work now.

I think this can be closed. It works for me in julia v1.11, ProgressMeter v1.10.0 and julia-vscode v1.90.1.
