Prefix and SSH indicator

• Icon indicator when a pane is maximized in a window
• Icon indicator for active SSH session
• Color indication when tmux prefix is pressed
• Bell and activity notifications properly displayed with custom styles

This plugin uses Nerd Font icons, make sure you are using one in the terminal to work properly. If you don't want it, you can change the icons to something else.

1. Install TPM

2. Add the plugin:

   set -g @plugin 'vaaleyard/tmux-dotbar'

3. Inside tmux, use the tpm install command: prefix + I (default prefix is ctrl+b)

This theme works best depending on the colorscheme you use, because the status-bar background is supposed to mix with the terminal background. The default colorscheme used for this theme (as in the preview images) is neovim-ayu in Ghostty, so it matches the background for my tmux, terminal and vim colorscheme.
It's strongely recommended to change the colors so it matches your colorscheme. You can get the colors from your preferred theme palette and change/set these options:

# supposing you use catppuccin moccha
set -g @tmux-dotbar-bg "#1e1e2e"
set -g @tmux-dotbar-fg "#585b70"
set -g @tmux-dotbar-fg-current "#cdd6f4"
set -g @tmux-dotbar-fg-session "#9399b2"
set -g @tmux-dotbar-fg-prefix "#cba6f7"

You can also set @tmux-dotbar-bold-status to use bold font in the statusbar, or @tmux-dotbar-bold-current-window to use bold font just for the active window.

You may feel the right part a bit empty. If you want, there's an option to display the current time there, you can enable it (disabled by default) in your .tmux.conf:

set -g @tmux-dotbar-right true

If you want to change it completely, you can, just modify the variable tmux-dotbar-status-right accordingly. Another option you might want to try is to change the position of the status-bar with tmux-dotbar-position (bottom by default):

set -g @tmux-dotbar-position top

When you ssh into a server, tmux-dotbar will change the window name to the SSH hostname and it will also add an icon indicator. Unfurtunately, tmux can't parse the window name when the SSH host is an IPv4 address. It gets truncated in the middle, e.g., ssh user@192.168.1.100 would show only 192.168. So for IP hosts this feature is not available.
Due to this limitation, I've addded the option to only display the icon (and don't change the window name) as it might cause confusion if you use IPs extensively, because you would not be sure if the window name is the host or not. If that's not the case, you don't need to change these settings. An option to do not show the icon is also available.

set -g @tmux-dotbar-ssh-icon '󰌘'
set -g @tmux-dotbar-ssh-icon-only false
set -g @tmux-dotbar-ssh-enabled true

Since this theme does not display window indexes, it's best suited for users who manage a small number of windows.
To improve usability, it's hugely recommended to enable automatic renumbering when windows are closed.
Also a good option is to start window indexes at 1 for easier tracking.

set-option -g renumber-windows on
set -g base-index 1
setw -g pane-base-index 1

Below are all the options you can change, with the default values. You can look at dotbar.tmux for more reference.

set -g @tmux-dotbar-fg "#0B0E14"
set -g @tmux-dotbar-bg "#475266"
set -g @tmux-dotbar-fg-current "#BFBDB6"
set -g @tmux-dotbar-fg-session "#565B66"
set -g @tmux-dotbar-fg-prefix "#95E6CB"
set -g @tmux-dotbar-position "bottom"
set -g @tmux-dotbar-justify "absolute-centre"
set -g @tmux-dotbar-left "true"
set -g @tmux-dotbar-status-left "#S" # see code
set -g @tmux-dotbar-right "false"
set -g @tmux-dotbar-status-right "%H:%M" # see code
set -g @tmux-dotbar-window-status-format " #W "
set -g @tmux-dotbar-window-status-separator " • "
set -g @tmux-dotbar-maximized-icon "󰊓"
set -g @tmux-dotbar-show-maximized-icon-for-all-tabs false
set -g @tmux-dotbar-bold-status true
set -g @tmux-dotbar-bold-current-window false
set -g @tmux-dotbar-ssh-enabled true
set -g @tmux-dotbar-ssh-icon '󰌘'
set -g @tmux-dotbar-ssh-icon-only false

This theme was inspired on minimal-tmux-status.
