    Gradualizer is a typechecker for Erlang. It's a bidirectional typechecker, which means it uses non-local type inference, i.e. a blend of typechecking with type inference. It aims to follow the principles of gradual typing, so that it's possible to add type annotations only to parts of your code, instead of the entire code base, and it's going to work with that. One of the eqwalizer authors, Ilya Klyuchnikov, contributed to Gradualizer in the past.
  • [New] How do you verify program correctness in Elixir?

    [Gradient](https://github.com/esl/gradient) and [Gradualizer](https://github.com/josefs/Gradualizer) offer exhaustiveness checking for Elixir and Erlang, respectively. The projects are in development, there are known issues so YMMV, but we're working on them.

    If you're looking for compile-time (or actually check-time) feedback you might be interested in Gradient, a gradual type checker for Elixir and a frontend to Gradualizer. These tools, while experimental, allow for applying "making illegal states unrepresentable" principle thanks to exhaustiveness checking. In general, they are more akin to the ML-style type checking than Dialyzer is.
  • OCaml Programming: Correct and Efficient and Beautiful

    I'm hoping that https://github.com/josefs/Gradualizer and its Elixir counterpart get us closer to what "I" want. I find dialyzer often inscrutable compared to something like OCaml's or Haskell's type errors.

    I do still use it and typespecs, because it's better than no checking.

    There's Gradualyzer with support for Gradual Typing on the way.
  • V0.14 of Gleam, a type safe language for the Erlang VM, has been released

    There's an effort currently being led by Facebook to create gradual type system for Erlang call Gradualizer, which should also make its way over to Elixir.
