Hello, isn"t this better on the first line?

!/usr/bin/env bash

(this works on systems, where bash is not in /bin/bash - like FreeBSD)

Hey there!
I used your brilliant code to script a simple volume notification under xfce and void linux.
The issue that I have is that the notifications will not appear in the position specified under Settings Manager > Notifications. No matter what I do, the notification appears in the upper right corner.
Any hint to what I'm doing wrong or what I can do to change the position another way somehow?
(I cannot use the -h int:x/y:value hint, because xfce-notifyd does not understand these.)

Any help would be appreciated! Thanks!

Is there any way to add color to the text ?

notify-send.sh -t 4000 "<i>Time Now</i>" "<span color='#57dafd' font='26px'><i><b>color text</b></i></span>" >/dev/null 2>&1

Doesn't seem to work

I am using Manjaro with i3-gaps wm. I tried all combos but didn't work.
I am using fish if it matters.
I tried it in bash also, but same thing.
I have glib2 installed too.
Also it takes about 50 seconds to run the command then nothing happens.
Is there logging functionality? I can't find it.

Hi, I have a bash script which does some actions and then display a notification which contains the --action= flag, which does other actions, is set as follow:

notify-send.sh -u critical -t 0 -o Execute:'command1; command2' --icon=/path/to/icon/icon.png " " "<span color='#F6FF45' font='16px'><b>$processname\nThe commands has been executed</b></span>"

After 'command1; command2' I would like to add another notification, so I tried:

notify-send.sh -u critical -t 0 -o Execute:'command1; command2; notify-send.sh -u critical -t 0 --icon=/path/to/icon/icon.png "$processname\nrestored"' --icon=/path/to/icon/icon.png " " "<span color='#F6FF45' font='16px'><b>$processname\nThe commands has been executed</b></span>"

Which half-works: the fact is that in the second notification, the new line parameter "\n" is not applyed and furthermore $processname\nrestored is not displayed at all, when in the first notification, is properly displayed. And if I execute notify-send.sh -u critical -t 0 --icon=/path/to/icon/icon.png "$processname\nrestored" alone, works as expected.
What I am missing?

What I have been able to achieve for now is:

notify-send.sh -u critical -t 0 \
 --icon=/path/to/icon/icon.png \
"$processname\nhas been paused and minimized" \
-o \
Resume:'notify-send.sh -u critical -t 0  --icon=/path/to/icon/icon.png \
"$processname \
Restored"'

In this way the second notification display the message, but the newline is not inserted (only in the first notification, the new line is inserted).

EDIT:

Well, I needed to escape the new line as follow:

"$processname \
\\n\
has been restored"'

Feel free to close this ticket, or to say anything about, if there is another way to achieve the aim :-)

This seems to depend on GDBUS explicitly, is it possible to add an option to support D-Bus directly?

I don't have anything gnome installed except the terminal, and the doesn't seem to be anything on the GDBUS.

But

dbus-monitor --session "type='signal',path=/org/freedesktop/Notifications,interface=org.freedesktop.Notifications"

correctly prints the action click messages

I can try to give you a PR if you're open to that

It would be great to add a python generated QR Code just big enough to be readable in the main body of the message.

$ sudo pip3 install pyqrcode
$ sudo pip3 install pypng

import pyqrcode
import png
from pyqrcode import QRCode

url = "http://www.example.com"
qrl = pyqrcode.create(url)
irl = "/tmp/qr_" + url.replace("://", "-") + ".png"

qrl.png(irl, scale =8, module_color=[0, 0, 0, 255], background=[0xff, 0xff, 0xff])

I had a few problems with this script, and ended up resolving them, and in the process did a complete re-write, or refactor more exactly.

I don't think you want my stylistic chnages (but I do) so I don't have a pull-request, however, I re-created a fresh git commit history in a fork where I tried to do most of the stylistic stuff in the first couple commits and then the rest of the commits show the functional changes more clearly.

You may or may not be interested, but here is the fork with a commit history that should be more or less readable so you can see how I got rid of all the seds and other unneeded external tools like bc and dc etc, and resolved my main problem which was background processes that just accumulated forever because of not really handling the conditions that can happen with notifications.

I tried to make each commit add one conceptual change. Not always perfectly but pretty close mostly.
You could also just look at the final/current version and probably get it.
https://github.com/bkw777/notify-send.sh

This version is now working well and bulletproof for me.

Two things I did which I want in my copy that you may not want are,
1 - I execute the action command directly, not with "bash -c". If I really need to execute a command that needs bash interpretation, like redirection, I'll just run bash as the command, and bonus, it doesn't have to be bash. Otherwise, the 99% common case is running a binary or script with args, and I'd rather optimize for that, no unnecessary extra shell process.
2 - I removed the use of printf %q on the action command in send.sh. I haven't missed it, and I think it was the cause of a cosmetic ugliness where the -d command or any -o command with empty button label, produced a button that looked like [ ' ' ] (I undertstand that could be dependat on the particular notification daemon, still, I no longer have that problem. Now if I specify and emty label, I get a clean blank button.) However, I haven't tried every crazy possible command string, just some basics that do include spaces and embedded escaped quotes etc, and they all worked. It's possible that without the %q there are command strings that used to work that now don't.

My use case:

1. Take a screenshot
2. Show a notification using this library saying it's uploading to hosting service, show a button to copy the raw image to clipboard in meantime
3. When done uploading, replace the original notification with one containing 2 buttons: one to copy the url of the image and one to copy raw image

Issue: notify-send with --action parameter won't return until action is triggered or notification expires. This means I can't start uploading the image until one of either happens.

Is there any way to make the action buttons keep working after the notification has timed out and gone to the notification daemon's history?

Example, my desktop default notification timeout is set to only 3 seconds. (lxqt-notificationd in my case). Notifications only appear briefly, then stack up in a history I can pull up when I want.

Now take this command:
notify-send.sh -o eyes:xeyes "" ""

If I press the "eyes" button during that first 3 seconds, it works.

If I allow the notification to expire, and then pop it back up from the history, the "eyes" button is still there and still clickable, but has no effect.

I see that during the initial display time there are two notify-action.sh processes that exist in the background while the notification is visible the first time. Once it times out, both of those disappear. When I pull the notification back up from the history, the bg processes do not reappear with it, so that surely explains why the button no longer functions.

Is there a way to make it so the monitor process doesn't go away until the user actively does something with the notification?

In my case, I'm trying to use this from within https://github.com/bkw777/mainline
In that context, it would be ok to have a single notification that gets refreshed or replaced rather than a stack of individual notifications. So maybe there is some way to rig this up using -p or -r or -R or something?

Otherwise, the best I can think of right now is I can override the timeout by using the -t option to specify a very long timeout, and maybe add the -f option, so that the notification never goes to the history, it's either visible and working, or totally gone.

After getting past the permission errors with (sudo sh), there are some additional problems:

(The script was run from the home folder).

sudo sh ./notify-send.sh --print-id Subject Message
./notify-send.sh: 23: ./notify-send.sh: Syntax error: "(" unexpected

I checked line 23 and this is what is in there:

NOTIFY_ARGS=(--session

It would be very nice of you to investigate this. Thank you. I really need that "re-draw" ish feature, as killing dunst every time I want to update causes uneccesary flickering due to the delay of restarting dunst (and I assume any other notification server).

GNOME made the (pretty weird) "design decision" to always ignore the expire time of notifications and even making all notifications persistent (the latter since the introduction of GNOME's notification center). Most applications bypass this behaviour by manually closing notifications after some individual timeouts (yes, instead of unifying expiration times, GNOME made it worse).

It would be great if notify-send.sh could easily bypass this behaviour, too. I wrote a simple wrapper script, even though implementing this into notify-send.sh's base script would obviously be simpler and a better approach:

#!/bin/bash
EXPIRE_TIME=-1
PRINT_ID=

NOTIFY_ARGS=()
while (( $# > 0 )); do
    case "$1" in
        -t|--expire-time|--expire-time=*)
            [[ "$1" = --expire-time=* ]] \
                && EXPIRE_TIME="${1#*=}" \
                || { shift; EXPIRE_TIME="$1"; }
            NOTIFY_ARGS+=( --expire-time "$EXPIRE_TIME" )
            ;;

        -p|--print-id)
            PRINT_ID=yes
            NOTIFY_ARGS+=( --print-id )
            ;;

        *)
            NOTIFY_ARGS+=( "$1" )
            ;;
    esac
    shift
done

NOTIFY_SEND="$(dirname "${BASH_SOURCE[0]}")/notify-send.sh"
if (( "$EXPIRE_TIME" != -1 )); then
    NOTIFICATION_ID="$("$NOTIFY_SEND" --print-id "${NOTIFY_ARGS[@]}")"
    NOTIFY_RC=$?

    if [[ -n "$PRINT_ID" ]]; then
        echo "$NOTIFICATION_ID"
    fi

    if (( "$EXPIRE_TIME" > 0 )); then
        SLEEP_TIME="$(bc <<< "scale=3; $EXPIRE_TIME / 1000")"
        ( sleep "$SLEEP_TIME" ; "$NOTIFY_SEND" --close "$NOTIFICATION_ID" ) &
    else
        "$NOTIFY_SEND" --close "$NOTIFICATION_ID"
    fi

    exit $NOTIFY_RC
fi

"$NOTIFY_SEND" "${NOTIFY_ARGS[@]}"
exit $?

$ ./notify-send.sh -t 60000 "Hello World!"

The notification is shown for the standard 5 seconds, not for 60 seconds as expected.

For me, when using options -o or -d (and even their long versions) it shows

Unknown option -o
