Setup

Add the .devcontainer directory to your Elixir project. The directory should contain the following files:

• devcontainer.json
• Dockerfile
• docker-compose.yml

See IEX Configuration section for details on the iex.exs file.

When prompted by Visual Studio Code, reopen the project in the container.

IEx Configuration

The iex.exs file is configured to make the Observer tool available in development mode. The configuration is as follows:

# Make observer available in development
if Mix.env() == :dev do
  Mix.ensure_application!(:observer)
end

Observer

To use Observer, follow these steps:

in IEx run :observer.start()

Connect your browser to the VNC server at http://localhost:6080/ and click on "Connect".

Observer Warnings

When using Observer, you might encounter the following warning:

[notice] wx: GTK: State 0 for context 0xfffeb06c5160 doesn't match state 128 set via gtk_style_context_set_state ()

Despite this warning, Observer should still work as expected.
