Request: Format-icons on disk and memory

[mahlquistj]

I would, personally, love for the disk-module to support this aswell. I know that it probably doesn't because you can't be sure which value it should use to determine the icons (e.g. should it use percentage_used or percentage_free).

My suggestion to applying this to disk could be introducing a format-icons-by value or alike. So that you could define it like so:

"disk": {
  "format": "{icon}",
  "format-icons-by": "{percentage_used}",
  "format-icons": ["" "󰪞" "󰪟" "󰪠" "󰪡" "󰪢" "󰪣" "󰪤" "󰪥"],
}

EDIT: Forgot to mention that the Memory-module does support format-icons, but it isn't documented in the wiki. Also i feel like if the above solution could apply, then the format-icons-by could be implemented for memory as well.

I think i managed this with the custom module:

"custom/disk": {
  "interval": 10,
  "exec": "bash $HOME/.config/waybar/scripts/disk-usage.sh 2> /dev/null",
  "return-type": "json",
  "format": "{icon}",
  "format-icons": ["󰝦", "󰪞", "󰪟", "󰪠", "󰪡", "󰪢", "󰪣", "󰪤", "󰪥"],
},

The script at "disk-usage.sh" looks like this:

#!/bin/bash

# Get disk usage percentage as an integer
percentage=$(df --output=pcent / | tail -1 | tr -d '% ')

# Define text, tooltip and class based on percentage
text="${percentage}%"
tooltip="Disk usage: ${percentage}% used"

# Set class based on usage thresholds
if [ "$percentage" -ge 90 ]; then
	class="critical"
elif [ "$percentage" -ge 75 ]; then
	class="warning"
else
	class="normal"
fi

# Output JSON that Waybar can parse
echo "{\"text\": \"$text\", \"tooltip\": \"$tooltip\", \"class\": \"$class\", \"percentage\": $percentage }"

@rlhf23 thank you for posting the script!

While i know you could do something like this with a custom module and script, i feel like this would be a great addition for the "standard" modules in waybar 😄
