Paconky: displays repo and AUR pkg info in conky

jrenong · 2011-11-20 14:11:16

hi i'm new in arch so hello everybody and i have a little problem with paconky.py i didn't modify the paconky.py and my conkyrc says " '/etc/pacman.conf',unrecognized option" and i'm a newbie in python so i don't know how to fix it

thanx

ps: i'm french so my english is possibly bad sorry

Hi,

I can't reproduce the error. Run the paconky command in a terminal and post the output. If you see this

${color1}${hr}
${color1}[${color2}core${color1}]                    ${color3}6 new packages
bash                           4.2.020-1

then paconky.py is working correctly.

The error may be in your conky configuration file. Post that too.

hi,
in my terminal i see this

$ .conky/paconky.py /tmp/paconky
('/etc/pacman.conf', 'unrecognized option', 'ILoveCandy')
Traceback (most recent call last):
  File ".conky/paconky.py", line 238, in <module>

Exception ValueError: 'I/O operation on closed file.' in <_io.TextIOWrapper name='/dev/null' mode='w' encoding='UTF-8'> ignored

and when i run just .conky/paconky it says : no temporary path given

do you have an idea ?

Xyne · 2011-11-25 23:05:38

You seem to have a line /etc/pacman.conf that begins with 'ILoveCandy'. That isn't a valid option and pyalpm therefore doesn't recognize it.

Fix pacman.conf and everything else should work.

jrenong · 2011-11-26 07:25:43

heuu Idon't know to say but i can't find it and if you don't put this line in the original script i probably don't have it

my paconky.py :

Yep. The problem was that the database lock was still in the directory. I just saw the ILoveCandy message and assumed that was the cause. If I had read to the end of the error message I would have seen that it was complaining about the lock. I was in a rush, sorry.

Paconky.py was probably killed while updating so it left the lock. If that happens again, you can always remove the lock file (db.lck) or the entire /tmp/paconky directory to fix it.

When I have some time, I'll update the script to either display a message about the lock or remove it directly.

ok thanx a lot xyne
I'll wait your update for the line but now it works

But I have a little problem
1) In the image in page one the version are aligne right but in mine it's not it's like center but not really
2) I want to know if you can put the size of each package an total size by type (extra, aur, etc) it's not really usefull but it could be nice if I can have it

thanx

Anyone know how to fix the hokey displayin paconky.py to something like ${alignr -10}? I've tried a few different ways with no joy. they display by pixel space.

guotsuan · 2011-12-23 20:23:14

I updated my pacman to version 4.0.1. It seems that the paconky is broken due to the new version of pyalpm that came with pacman.
It gave errors:

Traceback (most recent call last):
File "./paconky.py", line 240, in <module>
main(sys.argv[1])
File "./paconky.py", line 201, in main
installed = set(p for p in pyalpm.get_localdb().pkgcache)
AttributeError: 'module' object has no attribute 'get_localdb'

Xyne · 2011-12-30 08:56:56

@jrenong
1) I would have to see the output to know what's going on.
2) The pyalpm backend has full access to everything in the pacman database, so that's possible. It shouldn't be too difficult either if you know a bit of Python. When I get some time I might try to make paconky more customizable via a simplified formatting option, but ultimately it's easier to just let people modify the script directly.

@zero_one
I don't understand the question.

@guotsuan
If it's still broken when the new pyalpm gets out of testing then I will fix it. I would rather keep it working with the current release. I use it myself so I will notice if it breaks.

Hi,

When I run paconky from the command line, it seems to return the appropriate results, however, from conky I get:

I delete the db.lck file and I can run from the command line again...but not call it from conky.

my call from conky is

running from the command line I get:

forkboy · 2012-01-17 09:06:06

Xyne, pacman 4 is now in core, please fix paconky to work with it

zero_one · 2012-01-17 15:17:48

Here is the output of paconky.py with pacman 4

    installed = set(p for p in pyalpm.get_localdb().pkgcache)
AttributeError: 'module' object has no attribute 'get_localdb'

the new version of pyalpm is still in testing, Looks like we are waiting on pyalpm to update before anything can be done.

I am sorry but it is a bit confusing. The link paconky.py refers to to paconky.py udated on 2011-07-01 and not in 2012. Is this the script we need to use.

Yup, that was it thanks. Apparently I muddled the permissions when merging the pacman.conf with the .pacnew file.
