[Solved] AUR - search for recently orphaned packages

michis · 2016-02-01 12:53:54

Is there a way to search for recently orphaned packages in the AUR?

In the web search there is no such search option, or at least I can not find it.
There is the option to list all orphaned packages. Would be nice to be able to sort it by orphan-date.

I think this could help users that want to adopt packages finding new candidates.

Ok, there is the option to sort by 'Last modified'.
If orphaning a package counts as a modification then sorting by last modified will do what i am looking for.

So, new question is:
Does orphaning a package count as modification that is recognized by the 'Last modified' search filter?

No. The last modified field is only updated when a new PKGBUILD is uploaded afaik.

Ok, then back to the original question...

Here's a "poor man's" way to do it. Install python3-aur and save this script as e.g. "aur-orphans":

#!/usr/bin/env python3
import AUR.RPC
aur = AUR.RPC.AUR(full_info=False)
for p in aur.get('msearch', None):
  print(p['Name'])

Use the script to create dated orphan lists:

aur-orphans.py | sort > $(date +%F).txt

Run the script again another day to generate a new list and use comm to see the new orphans:

comm -13 old_list.txt new_list.txt

It should be easy to wrap that all up in a nice little script.

Thanks Xyne, I'll try it out..

Is the sort command necessary? Seems the output of the python script is already sorted...

michis · 2016-02-01 23:52:30

ok, it is ... comm: file 1 is not in sorted order

This is what I have so far...

#!/bin/bash

old_list=$HOME/.old-aur-orphaned.txt
new_list=$HOME/.new-aur-orphaned.txt

if [ ! -f ${old_list} ]; then
  echo "First run, creating initial list of orphaned packages."
  /usr/local/bin/aur-orphans | sort > ${old_list}
  exit 0
fi

echo "Creating list of current orphaned packages"
/usr/local/bin/aur-orphans | sort > ${new_list}

echo "Orphaned packages since last run:"
comm -13 ${old_list} ${new_list}
mv ${new_list} ${old_list}

Thanks again.

Replaced your python script with cower

#!/bin/bash

old_list=$HOME/.old-aur-orphaned.txt
new_list=$HOME/.new-aur-orphaned.txt

if [ ! -f ${old_list} ]; then
  echo "First run, creating initial list of orphaned packages."
  cower -qm "" | sort > ${old_list}
  exit 0
fi

echo "Creating list of current orphaned packages"
cower -qm "" | sort > ${new_list}

echo "Orphaned packages since last run:"
comm -13 ${old_list} ${new_list}
mv ${new_list} ${old_list}

This should work i think, but I am wondering if it's worth to file a feature request for an option to sort orphaned packages by orphan-date in the AUR web-interface?

Just in case it was because of the speed, I have added an option to increase it in the backend. It's now consistently just a little faster at retrieving the list than cower on my system

Anyway, use whatever works best for you.

And yeah, post a request to the aur-dev mailing list. There are a few ideas under consideration for the RPC interface so now is the time to throw your own into the mix.

The reason was: only one script, only one extra package (cower) needed.

Maybe i'll do it, yet undecided.

Little improvement of the output.
Now it prints highlighted package names and the package descriptions.

#!/bin/bash
#
# This script lists new orphaned AUR packages since it's last execution.
# Dependencies: coreutils grep cower

old_list=$HOME/.old-aur-orphaned.txt
new_list=$HOME/.new-aur-orphaned.txt

if [ ! -f ${old_list} ]; then
  echo "First run, creating initial list of orphaned packages."
  cower -qm "" | sort > ${old_list}
  exit 0
fi

echo "Creating list of current orphaned packages"
cower -qm "" | sort > ${new_list}
orphans=$(comm -13 ${old_list} ${new_list})

echo "Orphaned packages since last run:"
cower --color=always -i ${orphans} 2>/dev/null | grep -E "Name|Description"

mv ${new_list} ${old_list}

EDIT: Since the script works for me now, I'll mark the thread as solved.
