Unexpected EEx.Engine state

[HarshBalyan]

I am trying to update elixir from 1.7.4 to 1.16.2. I am running into a compilation error.

Compilation error in file lib/myapp/api/actions/support/some_action.ex ==
** (RuntimeError) unexpected EEx.Engine state: {{:., [], [{:__aliases__, [alias: false], [:EExHTML]}, :raw]}, [], [[]]}. This typically means a bug or an outdated EEx.Engine or tool
    (eex 1.16.2) lib/eex/engine.ex:218: EEx.Engine.check_state!/1
    (eex 1.16.2) lib/eex/engine.ex:181: EEx.Engine.handle_text/3
    (eex 1.16.2) lib/eex/compiler.ex:321: EEx.Compiler.generate_buffer/4
    (raxx_view 0.1.7) expanding macro: Raxx.View.__using__/1
    lib/myapp/api/actions/support/some_action:6: SomeAction (module)
    (elixir 1.16.2) expanding macro: Kernel.use/2
    lib/myapp/api/actions/support/some_action.ex:6: SomeAction (module)
    expanding macro: MyApp.API.SupportLayout.__using__/1

I have an action like

def SomeAction
  ...
    use MyApp.API.SupportLayout,
    arguments: [:transaction],
    template: Path.join(__DIR__, "transaction.html.eex")

...
end

Support Layout

defmodule MyApp.API.SupportLayout do
  use Raxx.View.Layout,
    optional: [
      page_title: "Admin",
      with_navbar: true,
      message: nil,
      message_type: "info"
    ]
end

EEx.Engine.check_state!/1 expects %{binary: _, dynamic: _, vars_count: _} which was added in Elixir v1.8. EExHTML.Engine.init/1 doesn't set any of these params.

Not sure if it's the best way but I've made it work for myself after making these changes. Let me know if it's good to go, I'll raise a PR. @CrowdHailer @ejc123

I'm not actively maintaining this. But if you open a PR I'll try and look over it

@CrowdHailer please, take a look at #11
