Highlighting style not working in tmux.

[mtbehisseste]

Everything is ok when using zsh. The highlighting style of autosuggestions(I changed it to fg=240) works. But when I use tmux, the color of the suggestions did not change to what I expected(fg=240). The color is exactly the origin command line color. Other functions like right arrow key to complete or command line suggestions work well. There's only problem about highlighting styles in tmux. Any suggestion?

I'm experiencing the same issue. I've enabled set -g default-terminal screen-256color in .tmux.conf, but this doesn't help. When tmux is closed, everthing works fine.

tmux suggestion color

outside of tmux session

Note that issue is also occurring on the git zsh plugin inside of tmux

tmux default TERM is screen：

$ env | grep TERM
TERM=screen

You can solve it like this:

echo  "export TERM=xterm-256color" >> ~/.zshrc
exec zsh

If you use MacOS iTerm2, you may need to modify the terminal type.

MacOS iTerm2:

Preferences -> Profile -> Terminal -> Report Terminal Type :  xterm-256color

Sounds like this is solved. Thanks everyone 👍

Just came across another relevant link. See the tmux FAQ: https://github.com/tmux/tmux/wiki/FAQ#how-do-i-use-a-256-colour-terminal

Setting the default term to xterm-256color in your .tmux.conf does the trick:

# Set default term to xterm
set -g default-terminal xterm-256color

You can solve it like this:

echo  "export TERM=xterm-256color" >> ~/.zshrc
exec zsh

Thanks. I made the block in .zshrc to make this only for tmux:

if [ ! "$TMUX" = "" ]; then export TERM=xterm-256color; fi

However, I have read that

Tmux REALLY wants the terminal set to screen or screen-256color

Would this workaround perhaps break other things?

Would this workaround perhaps break other things?

yes, neovim for example

[afirth]

my workaround (gnome terminal) is

term prefs -> profiles -> show bold text in bright colors

and

.zshrc

zle_highlight=(default:bold)
# change color for solarized dark
export ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE='fg=60' # makes it light grey, non bold

no doubt you can do the first part in gconf if you like

this causes text in the terminal to be bold (and bright) and suggestions to be "normal"

I know this is old, but in 2023 this still worked for me!

[DeepaPrasanna]

if [ ! "$TMUX" = "" ]; then export TERM=xterm-256color; fi

I have added this in .zshrc . this seems to not work for me. I have ubuntu 22.04

Using TPM (Tmux Plugin Manger) and the tmux-sensible plugin is another fix for this issue.
