Paconky: displays repo and AUR pkg info in conky

@enifeder
Remove the ~/.scripts/repos.paconky directory and install the latest version of paconky.py.

Seems to be doing something now. Although it says 'system is up to date' when it is not?

Paconky downloads its own copies of the sync database files.
It does that at whatever interval you set in the conkyrc file (which should be about 2 hours).

I'm guessing that you ran "pacman -Sy" and noticed upgradable files.
Paconky doesn't report them because it only checks its own database files.
Those will be updated at the end of the interval.

Yes I just noticed it now works. Thank you for helping me out

Paconky was working nicely but then I tried to modify conky ( adding some stuff for Deadbeef!!) and now paconky don't work no more .

[chris@alpha ~]$ conky -c ~/.conky_paconky
Conky: desktop window (15d) is root window

alpm.error: transaction could not be initialized, pm_errno 10 (unable to lock database)

I checked /tmp/paconky and couldn't see any lock file in there.

np

@lemmy999
If pyalpm reports that there's a lock file, then there's a lock file. Maybe it was gone by the time you checked.
Are you running multiple instances of paconky or letting something else use the temporary database?

I've updated paconky to catch that error and print the lock file path. Double-check that it really doesn't exist and try running paconky again.

lemmy999 · 2012-04-08 14:30:52

I'm away from my main PC ( where the problem is) for a couple of days. From memory I seem to recollect that there were two folders in /tmp/paconky. One contained three subfolders ( core/extra/community IIRC) and the other contained lots of folders ( probably one for each package updated since I installed paconky)

I am only running one instance of paconky.

I'll check when I get home on Tuesday and see if I can find that pesky lock file.

Xyne · 2012-04-08 17:20:00

I recommend that you remove /tmp/paconky. It only contains a symlink to the local database and separate copies of the sync database files. The former is recreated automatically if it's missing and the latter are downloaded as necessary.

lemmy999 · 2012-04-10 14:49:57

@Xyne

On reboot today everything was working exactly as it should.

Thanks for your help.

Doorbreath · 2012-04-10 18:26:51

My mirror syncs at half past the hour, I'd like my this script to update at say 35 mins past the hour so it's pretty much up to date all the time. I can't figure out a way to do it. I thought about something like killall -SIGUSR1 conky in cron to force conky to refresh? Seems a bit too kludgy though...

Xyne · 2012-04-11 17:40:39

@Doorbreath
You could run paconky in a cronjob and dump the output to a file every hour, then just read the file in your conkyrc.
Just make sure that the file exists (and is updated) when you start up the system (e.g. by running cronwhip before launching conky, or by execp'ing a script in conky that creates/refreshes the output file if it doesn't exist/is older than an hour).

lemmy999 · 2012-05-03 18:42:31

Decided to re-install Arch with a new /data partition. I am keen to use paconky again because it is so useful. I'm getting the following error when i run it from the terminal

[chris@alpha ~]$ sudo /home/chris/paconky.py /tmp/paconky
Traceback (most recent call last):
  File "/home/chris/paconky.py", line 77, in <module>

Can't find paconky in AUR? o_O

Xyne · 2012-08-24 00:15:53

Sorry for the late reply.

The original paconky, which was packaged, has been deprecated. The replacement script is not available in the AUR because it is just a example script that is mean to be hacked by each user. If it were installed as a package, you would need root privileges to edit it and it would be overwritten every time the package was updated.

You can use xacget to get the latest version of paconky whenever you need it. Just install it somewhere on your user's PATH (and edit it as necessary).

jaredanderson · 2013-04-13 16:47:10

Hey man I think this could be a problem with i3-bar or my conkyrc but I thought i would stop here first. When I run conky from the terminal paconky shows the expected output. but when it is piped through the i3bar everything appears as normal except paconky isn't there at all. here is my conkyrc

** you can ignore this it was with my conkyrc i am crazy

Okay I think I figured out the problem. Your Script comes with formatting which doesn't jell when piped to a bar. so basically i need all of the output in one straight line with no formatting. i figured out how to remove some formatting but i haven't figured out how to remove the indents' that is so that each repo isn't on a different line. so the script outputs something like

 core "x" new package xxxxxx
 extra "x" new package xxxxxx etc.

when i want it to output something like

 core "x" new package xxxxxx extra "x" new package xxxxxx etc.

here is my paconky thus far

Sry for the probably not so difficult question, but how would i tell the "paconky-script" to show me the number of available updates + let's say the first three upgradable packages? If i understand right, paconky will show me all the available updates, which will be a very long list if e.g. kde gets a new update. So it would be great to shorten that list in some way.

Xyne · 2013-10-10 21:56:08

Information about upgradable packages is passed to the display function at the top of the file. That can easily be configured to print out the number of upgrades and a subset of packages instead of the full list.

I don't have time to post an example right now, but I will try to remember to post one this weekend if no one else does before then. It you don't know any Python then you could use this as a reason to learn a little. You really don't need much and you could probably figure it out before I post an example.

tumas · 2013-10-11 13:26:51

I don't know any Python or any other programming language, but i looked around a little bit and tried something; i changed the code to the following:

....
 pkgs = sorted(pkgs, key=lambda x: x[0].name)
      for local, sync in pkgs:
        name, version = local.name, sync.version
        n = len(pkgs)
      if n < 4:
        print(line % (name, version), end='')
      else:
        print('\n${goto 32}Too many Updates')

...

This way it should show me only 4 Updates and if there are more, it should only show the message "Too many Updates". But i am not sure how i would tell it, to always show 4 Updates, even if there are 5 or more available. And the next problem seems to be, that "n < 4" applies to [core] or [extra] individually and not all of them together. My System is almost UpToDate (only 2 Updates available), but if i set this value to n < 2 it still shows me 2 package names (1 from [core] and 1 from [extra])

PS: It was just a try, so please bear with me

This will print out the number of upgradable packages followed by a list of up to 3 package. It should hopefully be clear how to modify it further.

Since the recent update to conky, pacconky stopped working for me. Displays nothing in conky and this is the output I get when running from a terminal:

Conky: desktop window (c00021) is subwindow of root window (9d)
Conky: window type - dock
Conky: drawing to created window (0x1200002)

    sp = p[1]

Does paconky need to be updated or does the solution lie somewhere else?

My local version which is mirrored on the site and linked in the first post still works. You seem to have modified it as my version does not contain "sp = p[1]", and the error appears to lie in the modification.

wankel · 2014-02-12 23:15:16

You're right, I'm using the def display function that you posted in post #222 (the one that allows for the actual package names and versions to be listed). In that you'll find the "sp=p[1]" line. Anyways if the original unmodified script still works I'll just use that, thanks.
