Notification hints

[jgroboredo]

Is your feature request related to a problem? Please describe.
For example, my volume control script uses value hints to show a "progress" bar in the volume notification:

notify-send -e -h int:value:"$(get_volume)" -h string:x-canonical-private-synchronous:volume_notif -u low -i "$(get_icon)" "Volume: $(get_volume)"

This causes an avalanche of notifications and no progress bar.

Describe the solution you'd like
I would like that every call to this script (that increases or decreases the volume by a certain amount) would result in a single notification with a progress bar update (each notification should be replaced).

Describe alternatives you've considered
No other alternatives considered.

Additional context
This should be a single notification with a progress bar:

Thanks in advance!

You can provide an ID in the notify-send command so that all messages originating from the same id won't spam you. To do this you can provide an -r 1234 flag where 1234 is your id.
Example:

notify-send -r 1234 -e -h int:value:"$(get_volume)" -h string:x-canonical-private-synchronous:volume_notif -u low -i "$(get_icon)" "Volume: $(get_volume)"

Thanks for your reply.

That does indeed work, but I'm still missing the display of the value hint. This is an example of the exact same notification using swaync:

And using AGS notification daemon:

Would an on-screen-display built separately for indicating volume and brightness changes be something you would desire as an alternative for having to handle such things via notifications?

[Jas-SinghFSU]

Also could you share your script please?

I think it would suffice, yes!

Also could you share your script please?

Here's the script:

get_volume() {
    volume=$(pamixer --get-volume)

        echo "Muted"
    else
        echo "$volume%"
    fi
}

# Get icons
get_icon() {
    current=$(get_volume)
    if [[ "$current" == "Muted" ]]; then
        echo "$iDIR/volume-mute.png"

Edit: This script is adapted from some other scripts I've found during the time - any resemblance is not coincidence, but I have lost the sources unfortunately.

Let me know if you need the icons for the notifications.

[Jas-SinghFSU]

Added on-screen-displays to indicate volume and brightness changes.

The settings for this can be configured in Configuration > General and coloring in Theming > OSD.

Great, looking forward to test it out!
