Terminal freeze after installing tab completions for fish shell

[andreatitolo]

Describe the bug
I installed the fish completions using kart install tab-completions --shell fish. When I start typing a kart command, pressing TAB freezes the terminal (doesn't matter the terminal emulator), without any completion showing up, and I am forced to quit the application.

I don't know if it matters, but fish is not my login shell.

To Reproduce
Steps to reproduce the behaviour:

1. Install fish completions
2. Type any kart command
3. Press tab to bring up completions
4. Terminal freezes

Expected behaviour
For the completions to show up properly and not freezing the terminal

Version Info

• OS: macOS 13.6.2
• Version: Kart 0.14.2
• Shell: Fish 3.6.1

Hi!

Can you try doing export KART_USE_HELPER=0 and see if that makes any difference?

[andreatitolo]

Setting set -gx KART_USE_HELPER 0 in my fish.conf (should be the equivalent of the above command) works! Just out of curiosity, what does that setting do?

[rcoup]

Thanks — we use a background helper to speed up process startup for Kart on macOS + Linux. I guess it's interacting funkily with fish or tab completion somehow.

[andreatitolo]

Thanks for explaining, I'll close the issue as I don't have any freeze anymore, and I did not notice any slowdown or similar.

[rcoup]

I'll reopen it until someone gets a chance to try and reproduce it or figure out what the issue is.

I'm getting this same behaviour on zsh (MacOS) and it's also kart-helper specific; tab completion works fine if the helper is disabled

[craigds]

actually a fresh kart install tab-completion --shell zsh fixes my zsh problem. so zsh must be not completely broken

However I can repro this with fish (and bash)
