Configure a rebar3 project

Before we can debug a rebar3 project with EDB, we need to configure a few things:

  1. Add edb as a dependency for the project
  2. Ensure we build the code using the beam_debug_info option

Since we want to only use the debugger to debug test and we don't want to affect production, these changes can be limited to the test profile.

Open the rebar.config file for the project and ensure edb is part of the deps key for the test profile. Also ensure the beam_debug_info option is included as part of erl_opts.

{profiles, [
    {test, [
        {deps, [
            {edb, {git, "https://github.com/WhatsApp/edb.git"}}
        ]},
        {erl_opts, [debug_info, beam_debug_info]}
    ]}
]}.
