# `Expresso.Slide`

A slide

# `t`

```elixir
@type t() :: %Expresso.Slide{
  __spark_metadata__: term(),
  auto_reveal: boolean() | nil,
  class: String.t() | nil,
  easing: atom() | nil,
  effect: atom() | nil,
  elements: list(),
  handout: Expresso.Handout.t() | nil,
  heading: String.t() | nil,
  labels: [String.t() | nil] | nil,
  meta: keyword() | nil,
  metadata: map() | nil,
  morph: :auto | :named | :off | nil,
  name: String.t() | nil,
  notes: String.t() | nil,
  section: String.t() | nil,
  speed: atom() | pos_integer() | nil,
  sr_heading: boolean() | nil,
  steps: pos_integer() | nil,
  template: module() | {:builtins, atom()} | nil,
  transition: atom() | nil
}
```

# `get_assigns`

```elixir
@spec get_assigns(t()) :: %{
  name: String.t() | nil,
  metadata: map() | nil,
  elements: list()
}
```

Make the assigns of a slide template from a slide

# `put_options_in_metadata`

```elixir
@spec put_options_in_metadata(t()) :: t()
```

Write the options of the DSL into the metadata of the slide

The `slide` entity puts the `heading` option into the `heading` field, and
the `notes` option into the `notes` field. The templates and the renderer
read each from the metadata. The `meta` option holds the values of the
user, and they stay under the key `:meta`, so a value cannot replace a key
of Expresso. This function puts each option that is not `nil` into the
metadata, and it gives the metadata an empty map when the field is `nil`.
