Conky v1.9 Thread

dk75 · 2013-01-12 17:12:59

When you think of cache, you think about web browser cache which checks if content changed (not every time, but it work, more or less ok).
But imlib2 has been strip of this functionality by design.
There is however separate function to check if source image had changed, but not implemented in Conky.
It could be a good thing to have "flush if changes" options to "${image}" function instead simple "flush"... it would be.

I want to make conky semi-transparent (like 50% opacity), but I can't figure out how to do it. I've read everywhere and have tried all combinations of "own_window" elements. I have xcompmgr on and would appreciate some help. Thanks.

EDIT: I got it, don't worry.

Hey!

I love the ${if_match ..} tag ever since i found it.
now i want it to run a little script for me (especially for my wife) whenever batterylvel runs low:

${if_match ${battery_percent} < 10}${color FF0000}${blink ${battery}}${exec ~/scripts/.batlow.sh}${color}${else}${battery}${endif}

but i am curious on how to tell conky to only run it once...
or to set the comand to run only ${if_match ${battery_percent} == 10} and to set the script to run only once in lets say 12 minutes ( to make sure ${battery_percent} changes during this intervall)?
or is there a way to force this in the script itself?

#!/bin/bash
#small and easy power notifierscript for #! waldorf

notify-send -i gtk-dialog-info -t 400000 -- "Achtung!" "Akku bald leer!" && cvlc --volume 512 ~/music/batlowsound.mp3

exit

i am really new to bash and don`t know if ther can be used a counter or something.

Thanks in advance!

Hey, after a long time of not contributing... here!
Here's what it looks like

I even included an installer.sh and uninstaller.sh that will keep your precious settings safe.
(although, I'm still new to this, so it'd be nice if someone could check it for me)

And it should be noted, that the most I did was add a few tweaks to the .conkyrc and add an installer and uninstaller.

edit: cleand up conky line

there is something you can try

check this

:~$ df -h |grep '/run/lock'
tmpfs           5,0M     0  5,0M   0% /run/lock
:~$

if it's "tmpfs" for you too, then we are home.
TMPFS is special filesystem residing in RAM (I've moved my /tmp into it ) so it means any operation on it are fast.
If so, making file in it and checking from BASH if it exist shoulden't be a burden to the system (system is doing it all the time).
So, your BASH code should look like that:

#!/bin/bash
#small and easy power notifierscript for #! waldorf

if [ ! -e /run/lock/battalarm ]   #IF NOT EXIST /run/lock/battalarm THEN
then
   touch /run/lock/battalarm   #CREATE /run/lock/battalarm
   notify-send -i gtk-dialog-info -t 400000 -- "Achtung!" "Akku bald leer!" && cvlc --volume 512 ~/music/batlowsound.mp3
fi

exit

and you should add something to clear that file in Conky $else function:

${if_match ${battery_percent} < 10}${color FF0000}${blink ${battery}}${exec ~/scripts/.batlow.sh}${color}${else}${exec bash -c 'if [ -e /run/lock/battalarm ]; then rm -f /run/lock/battalarm; fi'}${battery}${endif}

Hey, I grabbed chunks of conkys from the first few pages of this thread, that summed up the information I wanted to see and it works great. Only thing is the time is a 24 hour clock based instead of 12 a.m. and 12 p.m. Lemme post the conky here and could someone tell me what to replace with what in the area I underline?
Edit: underline and whatnot is not working, just look just under text and date and time is addressed under that header bit, first two lines under that, I think I need to change the code on the second line, but don't know the proper syntax for a 12 hour clock that might also have A.M and P.M as well as a plus. If it could use a sun and/or moon icons as night and day that would be epic but not necessary by any means.

change:

${time %H:%M}

to

${time %l:%M %p}

for a 12-hour clock indicating AM/PM -- use a capital "P" if you want lower case am/pm.

For all options:

man date

in a terminal.

You would have to use another script and/or clock if you want an icon changing with the time.

I'd like to share my basic weather script. I just wanted something basic and text-based, so I made one myself using yahoo's API. It just does current weather and two day forecast (limit of the API, I'm afraid, but all I need...). You'll need your location WOEID which you can lookup here: http://woeid.rosselliot.co.nz/lookup/

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import os, urllib
from xml.dom import minidom

location = '12345678' #WOEID

url = 'http://weather.yahooapis.com/forecastrss?w='+location+'&u=f'
xml = minidom.parse(urllib.urlopen(url))
#forecast = day : (dayname, high, low, description)
current = {'temp':-999, 'desc':'Default description'}
forecast = {} # day : (dayname, high, low, description)

a = xml.getElementsByTagName('channel')[0]
b = a.getElementsByTagName('item')[0]
c = b.getElementsByTagName('yweather:condition')[0]
current['desc'] = c.attributes['text'].value
current['temp'] = c.attributes['temp'].value

d = b.getElementsByTagName('yweather:forecast')
forecast['today'] = d[0].attributes['day'].value, d[0].attributes['high'].value, d[0].attributes['low'].value, d[0].attributes['text'].value
forecast['tomorrow'] = d[1].attributes['day'].value, d[1].attributes['high'].value, d[1].attributes['low'].value, d[1].attributes['text'].value

#Conky formatting (format1 is in front of the line, format2 is after the colon)
format1 = '${color 729FCF}${font Source Sans Pro Regular:bold:size=10}'
format2 = '$font$color ${goto 55}'
conky = '{0}Now:{1} {2}°, {3}\n'.format(format1, format2, current['temp'], current['desc'])
conky += '{0}{1}:{2} {3}° Hi, {4}° Low, {5}\n'.format(format1,forecast['today'][0],format2, forecast['today'][1], forecast['today'][2], forecast['today'][3])
conky += '{0}{1}:{2} {3}° Hi, {4}° Low, {5}\n'.format(format1,forecast['tomorrow'][0],format2, forecast['tomorrow'][1], forecast['tomorrow'][2], forecast['tomorrow'][3])

print conky

I use it like this:

${execpi 900 $HOME/weather.py}

Conky Weather

OK then, try

maybe it is not /run/lock but just /run, let's see

ok, this gives me:

Thank you man! I will try this and be right bacxk with the full setting if it works...
Thanks again!

will run your command every 60 seconds.
The if statement checks if it is time to run the command.
The os.execute() line runs the command without it being connected to conky so it will not lock up you conky if it runs slow.

I don't know for sure since you did not say how it failed.
Do you get any errors in the terminal?

One thing I see that could cause the wget command to fail is that you did not put any spaces between the variables join on this line.

os.execute("wget  -q -O"..file..web)

so your wget command may not be working unless you are passing the spaces to your function.
You are also leaving out the "" around the web address unless you are passing that to your function

I would recommend you change that line to be.

os.execute("wget  -q -O "..file..' "'..web..'"')

so it will work if you call the function like this.

webcam("http://www.eso.org/public/webcams/vlt.jpg", "/tmp/vlt.jpg")

Hint: /run have no access for normal user, but /run/lock have - use my code instead yours

i want to cut a string out of another string. therefore i need the position of the last appearance of a sign.

here is an example

the main-string:

http://www.eso.org/public/webcams/vlt.jpg

the part i'm looking for:

vlt.jpg

in this case i need the position of the sign /

i know that it is possible to find the last appearance of a sign (if u use other programming languages). but i do not know how do realize this in lua? does string.find has a parameter to find the necessary position? i can not find something

dk75 · 2013-01-15 04:36:02
