For anyone who uses the Fish shell.

function nvim-chad
    env NVIM_APPNAME=nvim-chad nvim
end

function nvim-yum
    env NVIM_APPNAME=nvim-yum nvim
end

function nvims
    set items nvim-yum nvim-chad
    set config (printf "%s\n" $items | fzf --prompt=" Neovim Config  " --height=~50% --layout=reverse --border --exit-0)
    if [ -z $config ]
        echo "Nothing selected"
        return 0
    else if [ $config = "default" ]
        set config ""
    end
    env NVIM_APPNAME=$config nvim $argv
end

bind \ca 'nvims\n'```

You should consider changing this to pass $argv to nvim in each of those functions so you can pass arguments. Otherwise you can't even use those aliases to open files from the CLI but have to use a picker from within neovim.

I just set the NVIM_APPNAME env variable to the directory name as per the commit. And so I just use the nvims function to set the desired config as environment variable. After this I can just use the regular nvim command to start the neovim in my desired config:

-- .zshrc

export DEFAULT_NVIM=<Your default conf directory within .config>
export NVIM_APPNAME=${DEFAULT_NVIM}

# Function to dynamically find and select Neovim configurations
function nvims() {
  local config_dirs
  config_dirs=$(find -L "${XDG_CONFIG_HOME:-$HOME/.config}" -mindepth 2 -maxdepth 2 -name init.lua -o -name init.vim | awk -F/ '{print $(NF-1)}')
  
  local config
  config=$(printf "%s\n" "default" $config_dirs | fzf --prompt=" Neovim Config  " --height=~50% --layout=reverse --border --exit-0)
  
  if [[ -z $config ]]; then
    echo "Nothing selected"
    return 0
  elif [[ $config == "default" ]]; then
    config=${DEFAULT_NVIM:-""}
  fi
  
  export NVIM_APPNAME=$config
}

You can set the default to your most frequently used

bind \ca 'nvims\n'
