bindkey -s ^a "nvims\n"

thanks a lot!

my configuration of zshrc for nvims here. made in macOS.

function nvims() {
  local nv_items=("Vanilla" "LazyVim" "NvChad")
  local nv_app=$(printf "%s\n" "${nv_items[@]}" | fzf --prompt=" Neovim Config 󰶻  " --height=~50% --layout=reverse --border --exit-0)

  if [[ -z $nv_app ]]; then
    echo "Nothing selected"
    return 0
  elif [[ $nv_app == "Vanilla" ]]; then
    nv_app=""
  else
    echo "Set $nvims_config to $nv_app"
  fi

  echo "$nv_app" > "$nvims_config"
  alias vi="NVIM_APPNAME=${nv_app} nvim"

  NVIM_APPNAME=$nv_app nvim $@
}

# nvims
if [[ -x /usr/local/bin/nvim || -x /opt/homebrew/bin/nvim ]]; then
  nvims_config="${XDG_CACHE_HOME:-$HOME/.cache}/nvims"
  nvims_app=$(cat "$nvims_config")
  #echo "Bind Neovim to $nvims_app"
  alias vi="NVIM_APPNAME=${nvims_app} nvim"
  export EDITOR="vi"
  bindkey -s "^v" "nvims\n"
fi

in terminal input nvims and enter not a valid number: ~50 nothing selected what's wrong?

any news on this? I do have the same error while just using nvims without any argument. Using WSL2 - bash

I had the same error.
Fix was to make height=50% NOT height=~50%

Due to some changes on Nerd Font you may want to update the glyphs to: " Neovim Config 󰄾 "

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' --
}

Slightly more readable update:

function nvims() {
    NVIM_APPNAME="$(
        find -L "${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)" \
    nvim
}

can anyone give the snippet for nushell please

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'
Pressing ctrl+A shows:

❯ nvims
: command not found

I personally prefer to put the default config inside ~/.config/nvim and the other configs inside ~/.config/nvims/<config_or_distro_name> so here's my version of nvims (renamed to nvim_switch_configuration) which combines andyantrim's and mikeslattery's approaches which might be useful for some:

alias nv='nvim'
alias nvs='nvim_switch_configuration'

nvim_switch_configuration () {
  config="$(
    find -L "${XDG_CONFIG_HOME:-$HOME/.config}" -maxdepth 3 -mindepth 2 -name "init.lua" -o -name "init.vim" \
    | awk -F"${XDG_CONFIG_HOME:-$HOME/.config}/" '{sub(/nvims\//, ""); sub(/nvim/, "default"); sub(/\/init.*/, ""); print $NF}' \
    | fzf --border --exit-0 --height=~50% --layout=reverse --prompt ' Neovim configuration switcher  ')"
  if [[ -z $config ]]; then
    printf "%s\n" "No configuration selected."
    return 0
  elif [[ $config == "default" ]]; then
    config=""
  else
    config="nvims/$config"
    alias nv="NVIM_APPNAME=$config nvim"
  fi
  NVIM_APPNAME=$config nvim "$@"
}

Here's also a version using fd instead of find:

alias nv='nvim'
alias nvs='nvim_switch_configuration'

nvim_switch_configuration () {
  config="$(
    fd -d 3 -L --min-depth 2 --regex "init\.(lua|vim)" -p "${XDG_CONFIG_HOME:-$HOME/.config}" \
    | awk -F"${XDG_CONFIG_HOME:-$HOME/.config}/" '{sub(/nvims\//, ""); sub(/nvim/, "default"); sub(/\/init.*/, ""); print $NF}' \
    | fzf --border --exit-0 --height=~50% --layout=reverse --prompt ' Neovim configuration switcher  ')"
  if [[ -z $config ]]; then
    printf "%s\n" "No configuration selected."
    return 0
  elif [[ $config == "default" ]]; then
    config=""
  else
    config="nvims/$config"
    alias nv="NVIM_APPNAME=$config nvim"
  fi
  NVIM_APPNAME=$config nvim "$@"
}
