Vscode-julia 1.2.4 fails with alt + enter execution (ctrl+enter works)

update: tried the same setup with standard Julia 1.6.1 (as opposed to custom compile) and everything checks out. There should be something wrong with my Julia compile.

On vscode 1.57.0 with julia 1.5.3 the ALT+ENTER execution fails with the error below. Anyone else with similar experience? Can someone point me to the direction where I could start digging/unravelling the error message below?
best wishes: steven

I also keep having problems with ALT+ENTER on and off. Sometimes highlighting the code block helps , sometimes not. Sometimes it recognises the code blocks sometimes it doesn’t. No idea how to reproduce.

I don’t have such problems, but I do have a huge delay (tens of seconds) on Windows after starting a fresh vscode and Alt+Enter first line of code - and before “executing” symbol starts to show next to the line. Sometimes it is even longer, if REPL starts with Precompiling VSCodeServer message (I suppose due to vscode or Julia plugin updates).

there is also a freeze during package indexing, but then at least I see something is happening.

yes, this is something to do with Julia infrastructure. I gutted/hacked a previous vscode-julia in December, 2020 with success; but 1.4.2 has gone a long way since in features and footprint. For good experience you need fast computer/ good setup and plenty of memory.

I managed to upgrade to v1.4.2 using vanilla Julia; for now I got good experience. I am thankful for the authors to make this happen.

I’ve noticed this can happen when you have a syntax error, which is understandable.

that’s a great point, thank you.

But it isn’t just that. For me the worst case actually is when I’m developing code within a @testset begin ... end block. ALT+enter then just executes the entire test set, so I always have to highlight the code I want to execute, or to comment (and later again uncomment) the testset block lines.
