Feature Request: Automatic finding of .pacnew files

[cornytrace]

This already very useful program can be made even better by adding a mode in the vein of etc-update where it automatically finds all .pacnew files for quick and easy resolving after a large update, and to find .pacnew files you didn't even knew existed on your system.

[mberlinger3]

Does this work?

#!/usr/bin/bash

for FILE in $(pacdiff -o | grep "/*.pacnew"); 
do
    p3wm ${FILE}
done 

[cornytrace]

That absolutely works, however it would be nice to have it integrated into the program so remembering/typing the script or making an alias isn't necessary. Losing pacdiff as a dependency would also be nice.

[mberlinger3]

I think I see a way to integrate it but it would require using my script as main() and checking for a specific flag/arg else passing to the original function. Maybe $p3wm find would work. I'm not sure how to find .pacnew files efficiently without $pacdiff -o but I'm fairly certain that most people looking at this would have it installed.

pacdiff does nothing more nothing less than find/mlocate on the /etc dir, you can check the code and see for yourself you can replicate the behaviour of pacdiff -o trivially with:

find /etc -name '*.pacnew'

and integrate it with p3wm with:

find /etc -name '*.pacnew' -exec p3wm {} \;

I checked the code and saw for myself ;) Looking at the contents of /usr/bin/pacdiff, it seems that the default behaviour of pacdiff is to scan /var/lib/pacman/local/*/files (it also has --locate and --find options that make it use those instead). As @cornytrace mentioned, the default behaviour also finds files outside of /etc.

[jheidbrink]

By the way I'm currently using pacdiff --output | grep "/*.pacnew" | xargs --max-args=1 --no-run-if-empty --open-tty sudo p3wm (I took the solution from @mberlinger3 but used xargs instead of a for-loop). Personally I'm fine with having a dependency on pacdiff.

Any update on this?

Now I'm questioning myself why I wrote this script in the first place instead of just using pacdiff.

[KAGEYAM4]

I am new to this .pacsave & .pacnew concept.

Found this on archwiki, currently i have pacdiff p3wm and pacdiff-pacman-hook-git. What benefit does p3wm provides over default pacdiff ? Also pacdiff-pacman-hook-git launches pacdiff, is there a way to have same behaviour for p3wm.

Note - i just installed these 3 and haven't seen them in action yet.

[5long]

(back from another hiatus)

@KAGEYAM4 right now, p3wm doesn't provide any benefits over pacdiff. p3wm was developed as an accident since I didn't know pacdiff exists. But hey, now I can start piling new features onto this project without anyone else's permission.

Regarding a pacman hook for p3wm: this will be a different issue: #23

[5long]

Back to the original topic of this issue: if p3wm would support automatic finding of .pacnew files, it'll probably just copy the logic of pacdiff -o -p: reads potential .pacnew files from pacman DB. If a user wants to find the files in a different way they'll probably have to write their own glue script.

p3wm doesn't provide any benefits over pacdiff

p3wm provides a way to perform a three-way diff (using tools that support such a merge operation, such as meld), which is the primary reason why I looked into p3wm in the first place, though I admit it was only today because I've been neglecting pacnew updates in the past.

To me, it's rather that if p3wm has a way to automatically find remaining pacnew files, I wouldn't need to use pacdiff anymore to find these. However, piping the result of pacdiff --output into p3wm is fine for me and also allows for some flexibility like filtering out files you don't care about merging like the mirrorlist.
