After 10 years, I finally retired iTerm as my main terminal. After a few months of trying, I got to a Ghostty config I enjoy using. It opens with my main shortcut without the quick terminal, which doesn't support native tabs, and I use native tabs to keep one session per tab.

What annoyed me the most was a useless top row that only said 'zsh'. Whatever I tried, it stayed there, but after a while I got it the way I wanted. It works well and is faster than iTerm was. Here's my current config:

# Shell
shell-integration = zsh
command = /bin/zsh -l -c '"$HOME"/.tmux/tmx'
confirm-close-surface = false

# Font
font-family = JetBrains Mono
font-size = 12

adjust-cell-height = 20%

# Cursor
cursor-style = block
adjust-cursor-height = 20%
mouse-hide-while-typing = true

# Window
window-width = 999
window-height = 45
window-step-resize = false
window-position-x = 0
window-position-y = 0
window-padding-balance = false
window-padding-color = background
window-decoration = true

### macos
macos-hidden = always
macos-titlebar-style = tabs
macos-window-buttons = hidden
macos-titlebar-proxy-icon = hidden

### shell integrations
shell-integration-features = no-title

### Keybindings
keybind = global:shift+cmd+t=toggle_visibility
keybind = ctrl+a>n=next_tab
keybind = ctrl+a>p=previous_tab
keybind = super+r=reload_config

# Colors
palette =  0=#141414
palette =  8=#666666

palette =  1=#f38ba8
palette =  9=#f38ba8

palette =  2=#a6e3a1
palette = 10=#a6e3a1

palette =  3=#f9e2af
palette = 11=#f9e2af

palette =  4=#89b4fa
palette = 12=#89b4fa

palette =  5=#cba6f7
palette = 13=#cba6f7

palette =  6=#94e2d5
palette = 14=#94e2d5

palette =  7=#cccccc
palette = 15=#cccccc

background = #000000
background-opacity = 0.9
background-blur = 20
foreground = #cccccc
cursor-color = #cccccc
selection-background = #282828
selection-foreground = #cccccc

PS: the GitHub version has more in it, because I'm testing everything that can improve my workflow.

This only works with zsh, tmx, my whole tmux config and all its integrations. I'm not a tmux expert, but I think this is the part that did the job:

# Enable terminal title setting
set -g set-titles on

# Send user@host and the session name (#S) up to Ghostty as the window title
set -g set-titles-string "#(whoami)@#H 👻 #S"

set-option -g automatic-rename on
set-option -g automatic-rename-format '#(whoami)@#H 👻 #S'

This config is also available here.

It looks like this, just the way my old iTerm setup looked:

If you want to see my whole setup, my dotfiles repo has everything.

This feels like when I retired Sublime Text for Zed 2 years ago.
