Finally someone asked about that!

That's an alias I made (with some help from the Arch Wiki) that lets me search the AUR for a package using fzf and then install it.

alias get="paru -Slq | fzf --preview 'paru -Si {}' --layout=reverse --bind 'enter:execute(paru -S {})+accept'"

(replace paru with your AUR helper of choice if different, requires fzf)

Also, my neovim config is available in the link!
