Please consider supporting some kind of chaining model so we can work with the shell integration as needed. Even better - use the defacto package that has already been written. VSCode is the 3rd script that wants to mess with prompts and traps - but it's the first to completely ignore Please consider shipping this along side and sourcing/using it. If that is unacceptable, consider at least detecting this module has been loaded as documented in the repo - and using it: fwiw: iterm2 has very very similar functionality to the vscode shell integration, but I've been able to work with it. Although they embedded the script directly, they kept the compatible function names and mechanisms and interop fine.
I believe we have already fixed this: Adding to make sure
Well, line 100 breaks my prompt. Adding the line as the 1st line of vscpreexec shows why. I think perhaps there needs to be 1 more state 'not in prompt' that causes preexec to bail until all promptcommand processing is done. Alternatively, if this is all to send vsccommandoutputstart - it seems like using PS0 on bash = 4.4 would be a lot cleaner?
Hi This was on 1.67.2 with dropped in place.
We've made some big changes in the past few days around debug trap and PS1 handling in bash, I believe the issues here are fixed. We may at some point hook into similar to but for now that will just increase the number of cases we would need to test for (contributions very welcome).
Actually I'll keep this open with help wanted to track integrating with bash-preexec.
OK. Pulling the - Things look better, but not quite right. The problems I see (only when DEBUG trap is being used): Still seems to be not preserving $? for promptcommand Seems to execute the trap twice. repro with setup instructions below: Do 'cd' into some directory. The command '..' should then pop one directory up, but it will try to process twice and pop twice. Instead of 'success dots' in the gutter, all commands seem to think there are fail exit status. Here are my dotfiles: and a branch to help debug: The debug branch just build an array of what commands were that triggered the trap and print them at the start and end of building the prompt. It does show the trap being called twice when shell integration is enabled - and once otherwise. The repro environment/steps: Repros in OSX and WSL Ubuntu 22.04 for me. It uses dotbot. In a scratch user directory you can run ./install to link everything into ~/. Pass to ./install to avoid installing extra tooling it finds missing (pygments/tmux/coreutils)There is a script that get's sourced . This is the root of all evil. It's on the hacky side. The function is small and is (I believe) the only relevant part. I should stop using it, but it's sooooo_ ingrained into my muscle memory. To verify: Removing from makes everything work great with none of the above mentioned problems. One hack, that seems irrelevant is that uses debug trap directly, but also detects and uses the pre-exec infrastructure if it has been loaded (to not break iTerm2's shell integration). I appreciate the time and effort going into this feature. It's becoming a shockingly advanced embedded shell environment.
thanks again, planning on tackling this in June
I use just merged in a fix for this. It would be great if someone could help verify in tomorrow's insiders build as I'm not normally a user of bash-preexec.
Still some problems around . Very simple repro: clean environment. My bash and vscode versions are: use this .bashrc: For me (In WSL, repros in plain OSX): ! Without ! If extdebug works, then this would be the next simplest test (I think). Same clean environment. The following
Are there verif steps for this?

With the more complicated scenario, the decorations don't seem to show blue and red anymore. ! I realize that in the screenshot I forgot to add , but that didn't make a difference.
what is your exact debug trap when that happens?
