lemonbar full

Requeriments

  • Of course, lemonbar

  • Alsa-utils for volume indicator.

  • Conky for CPU, MEM, NET and DISK usage.

  • Curl for gmail alert.

  • Weechat for private messages alert. Bitlbee for twitter and chat protocols integration.

  • MPD and mpc for song info.

  • xprop for focus app indicator.

  • And finally, i3wm

Basically, how it works?

i3_lemonbar.sh bash script read the configuration from i3_lemonbar_config file.

Later, execute the requested apps for the diferent meter sections. The output is redirected to fifo file, adding 3 letters ID for each.

Finally, run a i3_lemonbar_parser.sh that read from fifo, check the ID meter, and converts it with lemonbar format.

Configuration

  • Change the bar section on i3wm config:

    bar {
        i3bar_command ~./.i3/lemonbar/i3_lemonbar.sh
    }
    
  • Adjust bar settings editing i3_lemonbar_config. Settings for:

    • Fifo file.
    • Bar geometry.
    • Normal and icon font. Here are my fonts used
    • CPU and NET usage alerts.
    • Colors
    • Specials symbols for separator (powerline).
    • Icons glyps.
