Wisdom is the prime thing

It’s been hard to find example awesomerc files to show how to use the progressbar and graph widgets in the awesome window manager. That’s understandable given the moving target. But, here’s the awesomerc file I’m using and the status.sh program that runs from my .xinitrc script. It currently works with commit b457c, based on the v2.1 tag.

Inside my .awesomerc

First of all, I have a few general additions to the default configuration:

general
{
    font = "terminus-9"
}
colors
{
    normal_border = "#2e3436"
    normal_bg = "#222222"
    normal_fg = "#aaaaaa"
    focus_border = "#336699"
    focus_bg = "#2e3436"
    focus_fg = "#c28457"
}

Here are the widget declarations I added:

    textbox tb1 { fg = "#336633" text = " CPU: " align = "right"}
    graph g_cpu
    {
        scale = false
        max = 100
        padding_left = 0
        width = 40
        height = "0.8"
        fg = "#551155"
        bg = "#000000"
        bordercolor = "#666699"
    }
    textbox tb2 { fg = "#336633" text = " Mem: " }
    progressbar pb_mem
    {
        bar { fg = "#551155" bg = "#000000" bordercolor = "#666699"  }
        width = "40"
        height = "0.4"
        gap = -1
        padding_left = 0
    }
    textbox tb3 { fg = "#336633" text = " | " }
    textbox tb_date { fg = "#c28457" text = "" }

You can download my latest .awesomerc here. Diff it with the awesomerc in the awesome distribution to see all my changes and upgrade to the latest version of awesome — it changes fast!

Lastly, my complete bin/status.sh

#/bin/bash
