Env setup

From https://code.visualstudio.com/docs/remote/create-dev-container#_automate-dev-container-creation:

1. In a new VSCode project, enter F1 and enter the command 'Remote-Containers: Add Development Container Configuration Files' and select the 'Elixir' docker.

2. Enter F1 again and enter the command, 'Remote-Containers:Open workspace in container'. Wait. Once complete, create a new VSCode terminal window. It should start in a container (and not on your host machine).

3. Note you may edit the contents of .devcontainer/ to get whatever env you'd like. Your .gitconfig is added by default. Your ~/.bash* files are not.

4. Rejoice and live better.

Playing around

Scripts

Elixir scripts use the .exs file-extension. They can be run like elixir script.exs.

REPL

From: https://elixirschool.com/en/lessons/basics/basics#trying-interactive-mode-2 In the container, type iex to start an interactive Elixir REPL.

Use iex filename.exs to load an Elixir file into the REPL.

Projects

Use mix project_name to start a new compiled (.ex) project.
