programs = {
    nushell = { enable = true;
      # The config.nu can be anywhere you want if you like to edit your Nushell with Nu
      configFile.source = ./.../config.nu;
      # for editing directly to config.nu 
      extraConfig = ''
       let carapace_completer = {|spans|
       carapace $spans.0 nushell $spans | from json
       }
       $env.config = {
        show_banner: false,
        completions: {
        case_sensitive: false # case-sensitive completions
        quick: true    # set to false to prevent auto-selecting completions
        partial: true    # set to false to prevent partial filling of the prompt
        algorithm: "fuzzy"    # prefix or fuzzy
        external: {
        # set to false to prevent nushell looking into $env.PATH to find more suggestions
            enable: true 
        # set to lower can improve completion performance at the cost of omitting some options
            max_results: 100 
            completer: $carapace_completer # check 'carapace_completer' 
          }
        }
       } 
       $env.PATH = ($env.PATH | 
       split row (char esep) |
       prepend /home/myuser/.apps |
       append /usr/bin/env
       )
       '';
