⚙ Customizing

Upgrading from v1? The section-based model replaces the old show_* / *_icon / use_bold options. See the migration guide for a complete mapping from old options to new ones.

Sections

The status bar is composed of configurable sections. Left sections go from outer to inner (a → d), right sections go from inner to outer (w → z). Empty sections are automatically skipped with correct arrow transitions. Section contents use tmux status formats, so values like #{USER}, #h, #S, and %T are expanded by tmux at render time.

+---+---+---+---+--------------------------------------+---+---+---+---+
| A | B | C | D |           ...windows...              | W | X | Y | Z |
+---+---+---+---+--------------------------------------+---+---+---+---+

The defaults are:

set -g @tmux_power_right_arrow_icon ''
set -g @tmux_power_left_arrow_icon  ''
set -g @tmux_power_left_a  ' #{USER}@#h'  # user@host
set -g @tmux_power_left_b  ' #S'          # session name
set -g @tmux_power_left_c  ''
set -g @tmux_power_left_d  ''
set -g @tmux_power_right_w ''
set -g @tmux_power_right_x ''
set -g @tmux_power_right_y ' %T'         # time
set -g @tmux_power_right_z ' %F'         # date

Each section can also have a style (e.g. bold, italics), applied via a _style suffix:

set -g @tmux_power_left_a_style  'bold'  # default
set -g @tmux_power_right_z_style 'bold'

Window and prefix-highlight styles are configurable through the same plugin option model:

set -g @tmux_power_window_current_style   'bold'  # default
set -g @tmux_power_window_last_style      'bold'  # default
set -g @tmux_power_window_activity_style  'bold'  # default
set -g @tmux_power_window_bell_style      'bold'  # default
set -g @tmux_power_prefix_highlight_style 'bold'  # default

To disable bold for the current window, window flags, and prefix highlight:

set -g @tmux_power_window_current_style   'none'
set -g @tmux_power_window_last_style      'none'
set -g @tmux_power_window_activity_style  'none'
set -g @tmux_power_window_bell_style      'none'
set -g @tmux_power_prefix_highlight_style 'none'

Advanced users can still overwrite native tmux options after the plugin loads, but the @tmux_power_* settings above are the supported tmux-power interface.

As an example, the following configurations can generate the theme shown in the first screenshot:

set -g @plugin 'wfxr/tmux-power'
set -g @plugin 'wfxr/tmux-net-speed'
set -g @tmux_power_theme 'everforest'
set -g @tmux_power_right_arrow_icon ''
set -g @tmux_power_left_arrow_icon  ''
set -g @tmux_power_left_a  '#{USER}@#h'
set -g @tmux_power_left_b  '#S'
set -g @tmux_power_left_c  '󰕒 #{upload_speed}'
set -g @tmux_power_right_x '󰇚 #{download_speed}'
set -g @tmux_power_right_y '%T'
set -g @tmux_power_right_z '%F'

Theme colors

You can define your favourite colors if you don't like any of above.

# You can set it to a true color in '#RRGGBB' format
set -g @tmux_power_theme '#483D8B' # dark slate blue

# Or you can set it to 'colorX' which honors your terminal colorscheme
set -g @tmux_power_theme 'colour3'

# The following colors are used as gradient colors
set -g @tmux_power_g0 "#262626"
set -g @tmux_power_g1 "#303030"
set -g @tmux_power_g2 "#3a3a3a"
set -g @tmux_power_g3 "#444444"
set -g @tmux_power_g4 "#626262"

Shell command integration

Section contents support tmux's #(cmd) syntax, so you can embed the output of any shell command. For example, to show weather in the status bar:

set -g @tmux_power_right_w '#(curl -s "wttr.in?format=1" | sed -e "s/+//" -e "s/ \+/ /")'

Other options

set -g @tmux_power_status_interval 1  # status bar refresh interval in seconds

The default arrows/icons and examples that include icon glyphs use characters from nerd-fonts.

📦 Plugin support

Any tmux plugin that exposes #{...} format tokens can be placed in a section.

tmux-net-speed

set -g @tmux_power_left_c  '󰕒 #{upload_speed}'
set -g @tmux_power_right_x '󰇚 #{download_speed}'

tmux-prefix-highlight

# 'L' for left only, 'R' for right only and 'LR' for both
set -g @tmux_power_prefix_highlight_pos 'LR'

tmux-mem-cpu-load

set -g @tmux_power_right_w '#(tmux-mem-cpu-load)'
