rebar3

ELP can auto-discover projects which contain a rebar.config or rebar.config.script. This requires rebar3 3.24.0 or greater.

Eqwalizer Support​

By default, ELP integrates with the eqWAlizer type checker. For this to work, you need to add the following to your project dependencies:

{deps, [
  {eqwalizer_support,
    {git_subdir,
        "https://github.com/whatsapp/erlang-language-platform.git",
        {branch, "main"},
        "eqwalizer/eqwalizer_support"}}
]}.

If you, instead, prefer to disable eqWAlizer support altogether (you will lose features such as types on hover), you can do so via the .elp.toml config file.

Troubleshooting​

My rebar3 project is not found​
