How to fix gap where background color is missing?

[mikehaertl]

I have a gap on the right side where the background color is missing:

I couldn't find a relevant configuration. In the default.sh theme file a TMUX_POWERLINE_DEFAULT_BACKGROUND_COLOR is set. But that's only used for the middle part (the window list).

So how can I get rid of that gap?

Here's what I changed in the default config:

export TMUX_POWERLINE_DEBUG_MODE_ENABLED="false"
export TMUX_POWERLINE_PATCHED_FONT_IN_USE="true"

export TMUX_POWERLINE_THEME="default"
export TMUX_POWERLINE_DIR_USER_THEMES="${XDG_CONFIG_HOME:-$HOME/.config}/tmux-powerline/themes"
export TMUX_POWERLINE_DIR_USER_SEGMENTS="${XDG_CONFIG_HOME:-$HOME/.config}/tmux-powerline/segments"

export TMUX_POWERLINE_STATUS_VISIBILITY="on"
export TMUX_POWERLINE_WINDOW_STATUS_LINE=0
export TMUX_POWERLINE_STATUS_INTERVAL="1"
export TMUX_POWERLINE_STATUS_JUSTIFICATION="left"

export TMUX_POWERLINE_STATUS_LEFT_LENGTH="30"
export TMUX_POWERLINE_STATUS_RIGHT_LENGTH="90"

export TMUX_POWERLINE_WINDOW_STATUS_SEPARATOR=""

# Override theme left/right segments and colors
TMUX_POWERLINE_LEFT_STATUS_SEGMENTS=(
	"tmux_session_info 148 234"
)
TMUX_POWERLINE_RIGHT_STATUS_SEGMENTS=(
	"tmux_mem_cpu_load 234 136"
	"date_day 235 136"
	"date 235 136 ${TMUX_POWERLINE_SEPARATOR_LEFT_THIN}"
	"time 235 136 ${TMUX_POWERLINE_SEPARATOR_LEFT_THIN}"
	"xkb_layout 125 117"
)

Hi @mikehaertl

I can not reproduce this behaviour with the changes you mentioned in config.sh.

To further investigate your issue, i can manually reproduce your behaviour by setting one of the following (not 100% sure your screenshot shows "black" or "transparent" background color):

• manually set status-style to "black" or "transparent":

  tmux set-option -g status-style bg=colour0
  

  (or tmux set-option -g status-style default for transparent)
• Set status-style in ~/.tmux.conf after loading tmux-powerline:

  set -g status-style bg=colour0
  

• Set TMUX_POWERLINE_STATUS_STYLE in config.sh:

  export TMUX_POWERLINE_STATUS_STYLE="bg=colour0"
  

To see if status-style is the problem you can run

tmux show-options -g status-style

in your running tmux session and check if output looks like:

status-style fg=colour255,bg=colour235

Besides that i don't have any concrete idea right now, but if you can provide some more information, i'll have another look.

Details

I couldn't find a relevant configuration. In the default.sh theme file a TMUX_POWERLINE_DEFAULT_BACKGROUND_COLOR is set. But that's only used for the middle part (the window list).

The TMUX_POWERLINE_DEFAULT_BACKGROUND_COLOR is being used in multiple other locations

• in lib/config_file.sh in function process_settings function to set default value for TMUX_POWERLINE_STATUS_STYLE, which is being used tmux internally for #[default]
  

  tmux-powerline/lib/config_file.sh

  Lines 73 to 82 in 717688b

  	# Set the default status bar colors to the theme's default colors. This section is here because it needs to be after the theme is sourced.
  	if [ -z "$TMUX_POWERLINE_STATUS_STYLE" ]; then
  	local bg_color
  	local fg_color
  	fg_color=$(__normalize_color "$TMUX_POWERLINE_DEFAULT_FOREGROUND_COLOR")
  	bg_color=$(__normalize_color "$TMUX_POWERLINE_DEFAULT_BACKGROUND_COLOR")
  	export TMUX_POWERLINE_STATUS_STYLE="fg=$fg_color,bg=$bg_color"
  	fi

• in lib/powerline.sh in function __process_colors function to set multiple default values for segment coloring
  

  tmux-powerline/lib/powerline.sh

  Lines 134 to 178 in 717688b

  	__process_colors() {
  	for segment_index in "${!powerline_segments[@]}"; do
  	local powerline_segment
  	read -r -a powerline_segment <<<"${powerline_segments[segment_index]}"
  	local separator_enable=${powerline_segment[7]}
  	# Find the next segment that produces content (i.e. skip empty segments).
  	for next_segment_index in $(eval echo "{$((segment_index + 1))..${#powerline_segments}}"); do
  	[[ -n ${powerline_segments[next_segment_index]} ]] && break
  	done
  	local next_segment
  	read -r -a next_segment <<<"${powerline_segments[next_segment_index]}"
  	if [ "${powerline_segment[1]}" = "default_bg_color" ]; then
  	powerline_segment[1]="$TMUX_POWERLINE_DEFAULT_BACKGROUND_COLOR"
  	fi
  	if [ "${powerline_segment[2]}" = "default_fg_color" ]; then
  	powerline_segment[2]="$TMUX_POWERLINE_DEFAULT_FOREGROUND_COLOR"
  	fi
  	if [ "$side" == 'left' ]; then
  	if [ "${powerline_segment[4]}" = "no_sep_bg_color" ]; then
  	powerline_segment[4]=${next_segment[1]:-$TMUX_POWERLINE_DEFAULT_BACKGROUND_COLOR}
  	fi
  	elif [ "$side" == 'right' ]; then
  	if [ "${powerline_segment[4]}" = "no_sep_bg_color" ]; then
  	powerline_segment[4]=${previous_background_color:-$TMUX_POWERLINE_DEFAULT_BACKGROUND_COLOR}
  	fi
  	fi
  	if __segment_separator_is_thin; then
  	if [ "${powerline_segment[5]}" = "no_sep_fg_color" ]; then
  	powerline_segment[5]=${powerline_segment[2]}
  	fi
  	else
  	if [ "${powerline_segment[5]}" = "no_sep_fg_color" ]; then
  	powerline_segment[5]=${powerline_segment[1]}
  	fi
  	fi
  	local previous_background_color=${powerline_segment[1]}
  	powerline_segment[7]=$separator_enable
  	powerline_segments[segment_index]="${powerline_segment[*]}"
  	done
  	}

• in lib/powerline.sh in function format which is being used in the default.sh theme, as well as for the hardcoded defaults for TMUX_POWERLINE_WINDOW_STATUS_CURRENT and TMUX_POWERLINE_WINDOW_STATUS_FORMAT.
  

  tmux-powerline/lib/powerline.sh

  Lines 51 to 68 in 717688b

  	local type="$1"

  	case $type in
  	inverse)
  	echo "fg=$bg_color,bg=$fg_color,nobold,noitalics,nounderscore"

@xx4h Thanks to your suggestions I found it. I had these hidden somewhere in my age old .tmux.conf:

# Set status line bg/fg colors
set-option -g status-bg black
set-option -g status-fg white

After removing them and restarting tmux everything looks good now 👍🏻 .

Thanks a lot!
