            Display spelling language when spell detection is enabled (if enough space is
            available).

            Set to 'flag' to get a unicode icon of the relevant country flag instead of the
            'spelllang' itself.

        Enable iminsert detection.

        Determine whether inactive windows should have the left section collapsed to only the
        filename of that buffer.
      '';

      inactive_alt_sep = helpers.defaultNullOpts.mkBool true ''
        Use alternative separators for the statusline of inactive windows.
      '';

      theme = helpers.defaultNullOpts.mkStr "dark" ''
        Themes are automatically selected based on the matching colorscheme.
        This can be overridden by defining a value.

        Note: Only the dark theme is distributed with vim-airline.
        For more themes, checkout the vim-airline-themes repository
        (https://github.com/vim-airline/vim-airline-themes)
      '';

      theme_patch_func = helpers.mkNullOrStr ''
        If you want to patch the airline theme before it gets applied, you can supply the name of
        a function where you can modify the palette.

        Example: "AirlineThemePatch"

        Then, define this function using `extraConfigVim`:
        ```nix
          extraConfigVim = \'\'
            function! AirlineThemePatch(palette)
              if g:airline_theme == 'badwolf'
                for colors in values(a:palette.inactive)
                  let colors[3] = 245
                endfor
              endif
            endfunction
          \'\';
        ```
      '';

      powerline_fonts = helpers.defaultNullOpts.mkBool false ''
        By default, airline will use unicode symbols if your encoding matches utf-8.
        If you want the powerline symbols set this variable to `true`.
      '';

      symbols_ascii = helpers.defaultNullOpts.mkBool false ''
        By default, airline will use unicode symbols if your encoding matches utf-8.
        If you want to use plain ascii symbols, set this variable: >
      '';

      mode_map = helpers.mkNullOrOption (with helpers.nixvimTypes; maybeRaw (attrsOf str)) ''
        Define the set of text to display for each mode.

        Default: see source
      '';

      exclude_filenames = helpers.mkNullOrOption (with helpers.nixvimTypes; maybeRaw (listOf str)) ''
        Define the set of filename match queries which excludes a window from having its
        statusline modified.

        Default: see source for current list
      '';

      exclude_filetypes = helpers.mkNullOrOption (with helpers.nixvimTypes; maybeRaw (listOf str)) ''
        Define the set of filetypes which are excluded from having its window statusline modified.

        Default: see source for current list
      '';

      filetype_overrides =
        helpers.mkNullOrOption (with helpers.nixvimTypes; maybeRaw (attrsOf (listOf str)))
          ''
            Define the set of names to be displayed instead of a specific filetypes.

            Example:
            ```nix
              {
                coc-explorer =  ["CoC Explorer" ""];
                defx = ["defx" "%{b:defx.paths[0]}"];
                fugitive = ["fugitive" "%{airline#util#wrap(airline#extensions#branch#get_head(),80)}"];
                gundo = ["Gundo" "" ];
                help = ["Help" "%f"];
                minibufexpl = ["MiniBufExplorer" ""];
                startify = ["startify" ""];
                vim-plug = ["Plugins" ""];
                vimfiler = ["vimfiler" "%{vimfiler#get_status_string()}"];
                vimshell = ["vimshell" "%{vimshell#get_status_string()}"];
                vaffle = ["Vaffle" "%{b:vaffle.dir}"];
              }
            ```
          '';

      exclude_preview = helpers.defaultNullOpts.mkBool false ''
        Defines whether the preview window should be excluded from having its window statusline
        modified (may help with plugins which use the preview window heavily).
      '';

      disable_statusline = helpers.defaultNullOpts.mkBool false ''
        Disable the Airline statusline customization globally.

        This setting disables setting the 'statusline' option.
        This allows to use e.g. the tabline extension (`|airline-tabline|`) but keep the
        'statusline' option totally configurable by a custom configuration.
      '';

      skip_empty_sections = helpers.defaultNullOpts.mkBool true ''
        Do not draw separators for empty sections (only for the active window).
      '';

      highlighting_cache = helpers.defaultNullOpts.mkBool false ''
        Caches the changes to the highlighting groups, should therefore be faster.
        Set this to one, if you experience a sluggish Vim.
      '';

      focuslost_inactive = helpers.defaultNullOpts.mkBool false ''
        Disable airline on FocusLost autocommand (e.g. when Vim loses focus).
      '';

      statusline_ontop = helpers.defaultNullOpts.mkBool false ''
        Display the statusline in the tabline (first top line).

        Setting this option, allows to use the statusline option to be used by a custom function
        or another plugin, since airline won't change it.

        Note: This setting is experimental and works on a best effort approach.
        Updating the statusline might not always happen as fast as needed, but that is a
        limitation, that comes from Vim.
        airline tries to force an update if needed, but it might not always work as expected.
        To force updating the tabline on mode changes, call `airline#check_mode()` in your custom
        statusline setting: `:set stl=%!airline#check_mode(winnr())` will correctly update the
        tabline on mode changes.
      '';

      stl_path_style = helpers.defaultNullOpts.mkStr "short" ''
        Display a short path in statusline.
      '';

      section_c_only_filename = helpers.defaultNullOpts.mkBool true ''
        Display a only file name in statusline.
      '';

      symbols = helpers.mkNullOrOption (with types; attrsOf str) ''
        Customize airline symbols.

        Example:
        ```nix
          {
            branch = "";
            colnr = " ℅:";
            readonly = "";
            linenr = " :";
            maxlinenr = "☰ ";
            dirty= "⚡";
          }
        ```
      '';
    };

  settingsExample = {
    powerline_fonts = true;
    theme = "base16";
    skip_empty_sections = true;
  };
}
