    (pkgs.vim_configurable.customize {
      name = "vim";
      vimrcConfig.vam.pluginDictionaries = [
        # vim-nix handles indentation better but does not perform sanity
        { names = [ "vim-addon-nix" ]; ft_regex = "^nix\$"; }
      ];
    })
  ];
}</syntaxHighlight>
=== vim-nix ===
vim-nix *only* supports syntax-highighting.

      name = "vim";
      vimrcConfig.packages.myplugins = with pkgs.vimPlugins; {
        start = [ vim-nix ]; # load plugin on startup
      };
    })
  ];
}</syntaxHighlight>
