Ok, but I was expecting something a bit more automated then opening a list of package in kate and comparing it to my list of installed AUR package... Plus it's 400 package so that's a lot of things to check and plenty of space to miss one package by manually checking.
But I get it I'm lazy and just need to script something myself. This is affecting so many people I thought we would have a script to check quickly if you are "infected".
It took Arch ~19 years just to get
archinstall.Something tells me there won't be a script.
Arch had curses based installator for a long time, it became unmaintained.
The link is a script
A lot of those 19 years were times where only nerds used arch.
CachyOS community seems to have a detection script, I have not vetted this run at your own discretion.

I haven't used kate but does it not have some sort of easy search?
ex. pacman -Qm to list AUR packages; should display the 3/4 pkgs you have installed. Then just search in kate for those 3/4 results?
Alternatively cat & grep in the terminal is pretty straight forward.
That is if it's 3/4 pkgs that are from AUR, but if someone has hundreds installed that is a bigger issue on its own.
Here's a script:

how many aur packages do you have? Most people i know have like AT MOST 20 or so packages from the aur. Which takes less then 2 mins to manually check against the list.
I'm not home for a few days so I can't check yet.
But I think I have something like 3/4 packages at the most.
But I need to compare that to a 400+ list I'm not sure I agree with you it's that easy to do rigorously.
Not sure I understand - if you only have 3-4 packages you can just search for them specifically in the long list?
Even if you have 50 or 100s of packages, bash makes it pretty doable
Should spit out only the packages appearing in both lists (done by memory so may not be 100%)
Damn how long is the list when you
Am I missing something ?
Just because I have 3/4 package on my system doesn't mean the 400+ list of affected package gets shorter on the other side...
I'm actually pretty cautious with AUR and I only install them when there is no other options.
Especially for a small list, 3-4, that you actually need to check, what's the actual issue? Open list of 400, ctrl+f for the few names you care about, move on.
I was just curious because I didnt think it was so tediuous to check against an alphabetical list on a website using ctrl+f. But thats just me. It took me less than a minute to check my 8 aur packages against the list
