Notify-send question [SOLVED]

firecat53 · 2010-11-01 21:46:51

Is there a way to have more recent notifications override older notifications of the same urgency? For example, I use a little script bound to my volume keys to adjust volume, and have a notification sent for each press. So if I press 5 or 6 times, I get notified for each. Is there a way to just see the most recent one?

Thanks!
Scott

I think it is best use a programming language for this.

There is examples of doing this with notify-osd:
https://wiki.ubuntu.com/NotificationDev … Guidelines
They are also in source of notify-osd.

What I did for showing bars with oss:

Bash script I call, if not showing bars, shows it.

oss_control

#!/bin/sh
SERVICE='oss_vol'
 
if ps -A | grep -v grep | grep $SERVICE > /dev/null
then
    echo "$SERVICE service running, do nothing"
else
    echo "$SERVICE is not running!" | oss_vol
fi

Python Script for manipulating bars:

oss_vol

#!/usr/bin/python2
# -*- coding: utf-8 -*-

import os
import time
import datetime
import pynotify
import procname

procname.setprocname('oss_vol')

class Bars(object):
    def __init__(self):
        self.num_bars = self.get_num_bars()
        self.last_update = datetime.datetime.now()

    def __str__(self):
        return self.get_bars()

    def get_num_bars(self):
        vol = os.popen('ossmix vmix0-outvol').read()
        vol = vol.split(' ')
        vol = vol[-2]

        vol = int(float(vol))

        return (vol*17)/25

    def get_bars(self):
        if self.num_bars != self.get_num_bars():
            self.num_bars = self.get_num_bars()
            self.last_update = datetime.datetime.now()

        return  '❚'* self.get_num_bars() + '➤' 


pynotify.init("oss_vol")
bars = Bars()
n = pynotify.Notification(str(bars))
n.show()
while True:
    if (datetime.datetime.now() - bars.last_update) > datetime.timedelta(0,1):
        break
    n.update(str(bars))
    n.show()

Call thought xmonad:
"ossvol -i && oss_control" to increase sound.
"ossvol -d && oss_control" to decrease sound.

Not best solution, the script could be a lot better, and faster.

Hmm, I'll have to give that a try when I get a chance. I was trying to just use libnotify and statnot to minimize the number of different notification scripts that I needed to run. I do recognize that some functionality may not be available this way, which was the purpose of my original question -- trying to squeeze the max function out of minimalist programs

Thanks for the input!

Edit: Solved, sort of. The statnot author released an update that allows notifications to __not__ be queued like normal. This basically gets the result I want.
