Strange terminal behavior when using zsh [FIXED]

Post by vxm5091 » Thu Jul 14, 2022 3:38 pm

Hello, I recently started using Nimble Commander and I was drawn to it in large part because of its smooth interoperability with the terminal. I also use iTerm2 with zsh. After setting the NC shell to zsh, I get this strange behavior when using ls commands -- most rows are highlighted and the text is blinking at the same rate as the cursor. The only fix I see at the moment is to switch back to a bash shell. Anything I can do to make the terminal more consistent with iTerm2 and keep zsh?

Hi, could you provide any instructions on how to reproduce the issue?

Thanks for the response Mike, I can figure out a repro though that might be a bit tough since I have Oh my Zsh and Powerlevel10k customizations as well.

This might be a helpful datapoint -- when running

Code: Select all

ls
, it seems like the terminal doesn't have any permissions to any of the files (see screenshot), regardless of the folder I'm in. If i run it with

Code: Select all

sudo
, the strange blinking goes away. So it seems to be related to permissions, and I'm still having this issue in admin mode. Is there any other setting I can tweak on the permission front?

That's a really weird behaviour, I don't think it's actually about permissions. What does 'pwd' say?

pwd shows the folder path as expected.

Well, no ideas at this stage...
If you could reproduce the issue in a sterile environment and provide instructions on how to replicate it - I'd be glad to look it.

I have the same problem of blinking text when listing files in the terminal using `exa`, and I have aliased `ls` to `exa with many flags`.

I do not get blinking when I use the actual`ls` command that ships with macOS:
`/bin/ls -l --color=always`

I also do not get blinking if I turn off the coloring for exa with `exa --color=never`.

So, at least for me, the problem is that the NC terminal cannot handle exa coloring. According to the exa website "it's designed for modern, 256-colour terminals, and it’s not shy about it!". NC also blinks when I try anything with `lsd`, another modern ls replacement.

It is an unfortunate limitation that the NC terminal TERM is `xterm-16color`. The built-in Terminal application upgraded to xterm-256color in 2010.

Ah, that makes sense, thanks.
Yes, NC's terminal emulator is currently limited to 16 colours and doesn't try to parse the xtem-256color input, likely that causes the issue.
To confirm that it's possible to start NC from another terminal and enable VT100 debug via Alt-Click at Help->Print VT100 commands.
It will then print the terminal commands flow it "sees".

Have the same issue. Just opened terminal via View->Show Terminal. Did nothing. The line is blinking.
Also all my settings is not working. Vim is different, colors is different. Is it possible to load my preferences by default?
