    > But .mli files do not help with the "no types in the source code" problém

    It partially helps since it forces you to have types where they matters most: interfaces.

    > And I did not experience any advantage of separate signature files so far,

    100kLoc is already quite big! I'm starting to think I'm an outlier since a lot of people don't see the benefits :)

    For me, it helps because I really don't want to see the implementation when I use an API. If I need to look at the implementation, it means the interface isn't well specified. All I need should be in the interface: types, docs, (abstract) types. And no more.

    Typically, an .ml file will have more than what is exported, types won't be abstract but will have a concrete implementation, and type signatures may be missing. How would it feels like to use list if only https://github.com/ocaml/ocaml/blob/trunk/stdlib/list.ml was available, instead of https://github.com/ocaml/ocaml/blob/trunk/stdlib/list.mli?

    Haskell tells you what is exported from a module, but it only shows you the names. To see the signatures, you need to rely on generated doc.

    Arguably, since OCaml has includes, it suffers from the same problem, your ".mli" may have tons of include and it becomes harder to see what's exported without an external tool

    > It partially helps since it forces you to have types where they matters most: exported functions

    But the problém the OP has is not knowing the types when reading the source (in the .ml file).

    > How would it feels like to use list if only https://github.com/ocaml/ocaml/blob/trunk/stdlib/list.ml was available,

    If the signature where in the source file (which you can do in OCaml too), there would be no problem - which is what all the other (for some definition of "other") languages except C and C++ (even Fortran) do.

    No, really, I can't see a single advantage of separate .mli files at all. The real problém is that the documentation is often worse too, as the .mli is autogenerated and documented afterwards - and now changes made later in the sources need to be documented in the mli too, so anything that doesn't change the type often gets lost. The same happens in C and C++ with header files.

  • Bringing more sweetness to ruby with sorbet types 🍦
    5 projects | dev.to | 18 Sep 2023
    If you have been in the Ruby community for the past couple of years, it's possible that you're not a super fan of types or that this concept never passed through your mind, and that's totally cool. I myself love the dynamic and meta-programming nature of Ruby, and honestly, by the time of this article's writing, we aren't on the level of OCaml for type checking and inference, but still, there are a couple of nice things that types with sorbet bring to the table:

  • What can Category Theory do?

    Haskell and Agda are probably the most obvious examples. Ocaml too, but it is much older, so its type system is not as categorical. There is also Idris, which is not as well-known but is very cool.

    That does sound problematic, but without the code it is hard to tell what is the issue. Typically, compiling a 6kLoc file like https://github.com/ocaml/ocaml/blob/trunk/typing/typecore.ml takes 0.8 s on my machine.

    NEAT is a fascinating algorithm. I've been interested in it ever since SethBling made a video about it playing Mario and this series of experiments about a variant of NEAT that evolves in real-time rather than by-generation. I'm finally getting to be just good enough of a programmer that I am actually considering writing my own (probably in OCaml because there's an unfortunate lack of NEAT implementations in functional programming languages).
