A type-checker for Erlang.

eqWAlizer is integrated and distributed with ELP (Erlang Language Platform).

1. Use OTP 26 or higher.
2. Install ELP.
3. Add eqwalizer_support dependency 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:

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

1. Use OTP 26 or higher.
2. Install ELP.
3. Write a project.json file describing your project.
4. From the project directory, assuming your .json file is called project.json run:

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

Please refer to the FAQ document for answers to some common questions, including:

• What's the difference between eqWAlizer and Dialyzer?
• Why not extend Dialyzer, rather than creating a new tool?
• What about Elixir?
