Hi! I’m pretty new to Doom Emacs, and Emacs in general, having only been using it for a couple of weeks. There are times where I would like to customize the configuration of a package, but I’ve been having trouble doing it without having to maintain a whole copy of the original config.el for that package. I must be doing something wrong, but I’m not sure what.
For an easy example, I would like to customize the display of ibuffer. I’m just looking to change the order of some columns, and create additional views to switch out others.
What happened?
I put the following into my personal config.el:
(after! ibuffer
(setq ibuffer-formats
;; Buffer name view
((mark modified read-only locked
" " (size 9 -1 :right)
" " (mode 16 16 :left :elide)
" " name)
;; File name and process view
(mark modified read-only locked
" " (size 9 -1 :right)
" " (mode 16 16 :left :elide)
" " filename-and-process)
;; minimal view
(mark modified read-only locked " " name " " filename)))
This kind of works, but the problem is that having this in my private config.el seems to completely override the one in emacs/ibuffer/config.el, and I wound up losing the projectile groups and the human-readable formatting for the size field.
I thought that in order to get it working correctly, I had to copy the whole emacs/ibuffer/config.el code into my private config.el and make the few changes I wanted to the (setq ibuffer-formats...) section. But either I messed something up in the copy process or doing that just doesn’t work, because it started complaining about a variable not being set in the after! block.
What did you expect to happen?
I thought that putting the code to override only the ibuffer-formats section would not wipe out everything else from the ibuffer config.el.

I feel like I’m just doing something wrong, but I’m not sure what it is. I’ve tried looking on the Doom Emacs Documentation site, but it seems to be missing a lot of information.
Any information or help is appreciated.
