# Helpers

Regardless of the way NixVim is used (as a home-manager module, a nixos module, or as a standalone module),
helpers can be included in the same way.

You can simply use:

```nix
{
    helpers,
    ...
}: {
    # Your config
}
```

A certain number of helpers are defined that can be useful:

- `helpers.emptyTable`: An empty lua table `{}` that will be included in the final lua configuration.
  This is equivalent to `{__empty = {};}`. This form can allow to do `option.__empty = {}`.

- `helpers.mkRaw str`: Write the string `str` as raw lua in the final lua configuration.
  This is equivalent to `{__raw = "lua code";}`. This form can allow to do `option.__raw = "lua code"`.

- `helpers.toLuaObject obj`: Create a string representation of the Nix object. Useful to define your own plugins.

- `helpers.listToUnkeyedAttrs list`: Transforms a list to an "unkeyed" attribute set.

  This allows to define mixed table/list in lua:

  ```nix
    (listToUnkeyedAttrs ["a", "b"]) // {foo = "bar";}
  ```

  Resulting in the following lua:

  ```lua
    {"a", "b", [foo] = "bar"}
  ```
