For zsh, I refactored the function so you don't need to hardcode the options; it finds any folder in ~/.config with an init.lua file in it and considers it a nvim config folder. Additionally, it adds a preview using lsd to display the folder contents.

function nvims() {
  items=$(find $HOME/.config -maxdepth 2 -name "init.lua" -type f -execdir sh -c 'pwd | xargs basename' \;)
  selected=$(printf "%s\n" "${items[@]}" | FZF_DEFAULT_OPTS="${FZF_DEFAULT_OPTS-} --preview-window 'right:border-left:50%:<40(right:border-left:50%:hidden)' --preview 'lsd -l -A --tree --depth=1 --color=always --blocks=size,name ~/.config/{} | head -200'" fzf )
  if [[ -z $selected ]]; then
    return 0
  elif [[ $selected == "nvim" ]]; then
    selected=""
  fi
  NVIM_APPNAME=$selected nvim "$@"
}
alias nvs=nvims

Nice, works well with eza too.

@wochap I tried your script on my setup and it doesn't seem to detect symlinks. I store all my configs under ~/.dotfiles and generate respective symlinks using Stow. To work around it, I simply added an extra folder to search.

	items=$(
		find $HOME/.config -maxdepth 2 -name "init.lua" -type f -execdir sh -c 'pwd | xargs basename' \;
		find $HOME/.dotfiles -maxdepth 5 -name "init.lua" -type f -execdir sh -c 'pwd | xargs basename' \;
	)

Rather than adding an extra folder to search, the find command can be altered either with:

find $HOME/.config -maxdepth 2 -name "init.lua" "(" -type f -o -type l ")" -execdir sh -c 'pwd | xargs basename' \;

or

find -L $HOME/.config -maxdepth 2 -name "init.lua" -type f -execdir sh -c 'pwd | xargs basename' \;

Either of those will pickup both plain files and symbolic links.

I also ran into a problem on an Ubuntu 20.04 system with the older version of fzf in their repo. It did not understand the preview options:

invalid preview window layout: right:border-left:50%:<40(right:border-left:50%:hidden)

I simplified the preview options to get it to work on that system:

selected=$(printf "%s\n" "${items[@]}" | FZF_DEFAULT_OPTS="${FZF_DEFAULT_OPTS-} --preview-window=right:50% --preview 'lsd -l -A --tree --depth=1 --color=always --blocks=size,name ~/.config/{} | head -200'" fzf )

My turn.

This uses the directory names of existing configurations. Someone else did the same, but my flavor is slightly shorter. Follows symlinks.

function nvims() {
    find -L "${XDG_CONFIG_HOME:-$HOME/.config}" -mindepth 2 -maxdepth 2 -name init.lua -o -name init.vim | \
        awk -F/ '{print $(NF-1)}' | \
        fzf --prompt 'Neovim config' --layout=reverse --border --exit-0 |\
        xargs -d$'\n' -n1 bash -c 'NVIM_APPNAME="$1" nvim' --
}
