This plugin provides the following functionality:

• Using Elixir itself as a dependency
• Compiling Elixir source files
• Building mix dependencies
• Additional commands for rebar3

Add the plugin to your rebar.config and configure it:

% The plugin itself
{plugins, [exerl]}.

% Inject step to consolidate protocols after compilation
{provider_hooks, [
    {post, [{compile, consolidate_protocols}]}
]}.

% Reference Elixir as a dependency
{deps, [
    {elixir_full, {ex, "1.17"}},
    % Use arbitrary hex dependencies...
]}.

Elixir files can be placed in the src directory.

The only additional command provided by this plugin right now is rebar3 iex which starts an interactive Elixir shell with the project's dependencies loaded:

$ rebar3 iex
