Neovim Switcher

.zshrc

alias nvim-lazy="NVIM_APPNAME=LazyVim nvim"
alias nvim-kick="NVIM_APPNAME=kickstart nvim"
alias nvim-chad="NVIM_APPNAME=NvChad nvim"
alias nvim-astro="NVIM_APPNAME=AstroNvim nvim"

function nvims() {
  items=("default" "kickstart" "LazyVim" "NvChad" "AstroNvim")
  config=$(printf "%s\n" "${items[@]}" | fzf --prompt=" Neovim Config  " --height=~50% --layout=reverse --border --exit-0)
  if [[ -z $config ]]; then
    echo "Nothing selected"
    return 0
  elif [[ $config == "default" ]]; then
    config=""
  fi
  NVIM_APPNAME=$config nvim $@
}

bindkey -s ^a "nvims\n"

For zsh, I refactored the function so you don't need to hardcode the options;

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:
