eqWAlizer

A type-checker for Erlang.

Using it with rebar3 projects

1. Use OTP 25
2. Download the elp binary for your system from https://github.com/WhatsApp/eqwalizer/releases
3. Add eqwalizer_support dependency and eqwalizer_rebar3 plugin to your rebar3 project definition (see below)
4. From the project directory run:

• elp eqwalize <module> to type-check a single module
• elp eqwalize-all to type-check all src modules in the project

Adding eqwalizer_support and eqwalizer_rebar3:

{deps, [
  {eqwalizer_support,
    {git_subdir,
        "git@github.com:whatsapp/eqwalizer.git",
        {branch, "main"},
        "eqwalizer_support"}}
]}.

{project_plugins, [
  {eqwalizer_rebar3,
    {git_subdir,
        "git@github.com:whatsapp/eqwalizer.git",
        {branch, "main"},
        "eqwalizer_rebar3"}}
]}.
