Today I decided to use a program known as i3blocks to customize my i3status. It allows me to run outputs of scripts and colorize sections as well.

Installing and configuring i3blocks

First you need to install i3blocks:

1
pacaur -S i3blocks-git

Then add the i3blocks script to your i3 config file.

bar 
	{
	status_command i3blocks -c ~/.i3/i3blocks.conf
	}

Now configure your i3blocks configuration file:

If you want to remove the separator from a section just include the line: separator=false

Configuring the Scripts

I modified many of the scripts I found on the i3blocks wiki

The Weather Script

I wanted to display weather on my i3status but I wanted to include icons to indicate the type of weather at a location. So I piped the curl script output in a perl script to print a font-awsome icon from a given weather condition.

The Gmail Script

The gmail script in the wiki was not parsing the xml correctly. I fixed the issue. The script shows the number of unread emails you have:

1
2
3
4
5
6
7
8
9
10
11
12
13
USER=Your_Gmail_Username
PASS=Your_Password
 
COUNT=`curl -su $USER:$PASS https://mail.google.com/mail/feed/atom || echo "<fullcount>unknown number of</fullcount>"`
COUNT=`echo "$COUNT" | grep -oPm1 "(?<=<fullcount>)[^<]+" `
echo $COUNT
if [ "$COUNT" != "0" ]; then
    if [ "$COUNT" = "1" ];then
        WORD="mail";
    else
        WORD="mails";
    fi
fi

The battery script

I made the batter script change icons when its charging vs discharging.

...
if ($status eq 'Discharging') {
    
	$full_text .= " $percent% Bat";
} elsif ($status eq 'Charging') {
	$full_text .= "⚡ $percent% Chr";
}
... 

The Volume Script

I had to modify the volume script, becuase I use an external sound card. This means amixer will not be able to see a master device.

amixer -c $CARD -M -D $MIXER get Headphone |

Here is the result of my configuration:
