Keep REPL open after crash

[akosuas]

I've got some code that segfaults (due to my stupidity, nothing to do with vscode). Unfortunately, when the REPL crashes, vscode seems to immediately close it, making it difficult to actually inspect the trace and work out what is going on. Is there a way to prevent vscode from closing the terminal automatically after it exits?

I'd also just like to more easily terminate the REPL (e.g. with Ctrl D) and have the option to restart it without it closing and then having to re-issue the VS Code command "Julia: Start REPL".

As far as I know, julia-vscode would then match the behavior in Juno:

This would be really helpful. Had some crashes lately that forced me to start a separate terminal so I could see why things crashed.

the current workaround is setting "julia.persistentSession.enabled": true, then you can see the trace on segfaults

[goretkin]

I haven't tried that setting yet. In what sense is it a workaround? What does it do?

[pfitzseb]

It runs Julia inside of a tmux session that's configured to stay alive even if the Julia process dies.

The more lightweight solution would be to point VS Code to a script like

#!/bin/bash 

JULIA=j1

if [ -z "${JULIA_LANGUAGESERVER}" ]; then
    ${JULIA} "$@"
    ret=$?
    if [ $ret -ne 0 ]; then
        read -rsn1 -p"Julia just crashed with $ret. Hit Enter to continue...";echo
    fi
else
    exec ${JULIA} "$@"
fi

The REPL crashes on launch with that setting for me.

I have the same problem, but on Windows the workarounds don't work.

I recall there being an upstream FR for supporting this in vscode but I can't find it. It'd be good to link it here if so
