安装

sudo pacman -S polybar

i3 配置使用 polybar

编写启动 polybar 的脚本

.config/polybar/polybar_run.sh#!/bin/bash

# 终端可能已经有在运行的实例
killall -q polybar

# 等待进程被终止
while pgrep -u $UID -x polybar >/dev/null; do sleep 1; done

# 运行Polybar，使用默认的配置文件路径 ~/.config/polybar/config
polybar mybar &

echo "Polybar runing..."

注释 i3 自带的 bar 或 i3blocks ，配置使用 polybar 启动脚本启动 polybar

#bar {
#	i3bar_command i3bar --transparency
#	status_command i3blocks
#	position top
#	colors {
#		background #9370DB3F
#		separator #778899
#			# 使用RGBA颜色  #边界 背景 文本
#		focused_workspace  	#778899A5 #87CEEBA5 #FFFAFAF5
#		inactive_workspace 	#7788993F #AFEEEE3F #FFFAFAF5
#		urgent_workspace   	#80808072 #FF450072 #FFFAFAF5
#    }
#}

exec_always --no-startup-id $HOME/.config/polybar/polybar_run.sh

定义自己的 polybar 配置

配置文件使用的是 ini 格式编写，具体每个插件查考官方 wiki 的说明(英文有些吃力就用翻译),也可使用第三方脚本插件。
