# `OpenUI.Program`
[🔗](https://github.com/ideia4it/openui/blob/v0.1.1/lib/openui/program.ex#L1)

A parsed program: its statements, the materialized entry, state defaults,
queries, mutations and the parse metadata of language.md, section 2.

`root` is the entry component with expressions still unevaluated in its
props. When the entry is an expression that picks a component at runtime
(`root = $dark ? a : b`), `root` is `nil` and `root_expression` holds it.

# `t`

```elixir
@type t() :: %OpenUI.Program{
  errors: [OpenUI.Error.t()],
  incomplete: boolean(),
  mutations: [OpenUI.Program.Mutation.t()],
  orphans: [String.t()],
  queries: [OpenUI.Program.Query.t()],
  root: OpenUI.Element.t() | nil,
  root_expression: OpenUI.Parser.Expression.ast() | nil,
  state: [{String.t(), term()}],
  statements: [OpenUI.Statement.t()],
  unresolved: [String.t()]
}
```
