Re: The Gleam Programming Language

I am in love with Gleam! As a young computer science student, I found that Gleam brought back the joy of programming just when I felt like I was seriously burning out. I was never a fan of functional programming languages. I had tried other BEAM languages like Elixir and Erlang before, but Gleam is the one I’ve enjoyed the most :)

Earlier quoted context omitted.

With all due respect, you can use all of those languages and their type systems without recognizing their value. For ensuring bits don't get lost, you use protocols like TCP. For ensuring they don't silently flip on you, you use ECC. Complaining that static types don't guard you against lost packets and bit flips is missing the point.

With all due respect, you really do not understand these protocols if you think “just use TCP and ECC” addresses my complaints. Again, it’s not that I have an issue with static types “not protecting you”, I am saying that you have to encode for this uncertainty regardless of the language you use. The way you typically encode for that uncertainty is to use an algebraic data type like Maybe or Optional. Checking agains…

Fair enough, though I feel so entirely differently that your position baffles me.

Gleam is still new to me, but my experience writing parsers in Haskell and handling error cases succinctly through functors was such a pleasant departure from my experiences in languages that lack typeclasses, higher-kinded types, and the abstractions they allow.

The program flowed happily through my Eithers until it encountered an error, at which point that was raised with a nice summary.

Part of that was GHC extensions though they could easily be translated into boilerplate, and that only had to be done once per class.

Gleam will likely never live to that level of programmer joy; what excites me is that it’s trying to bring some of it to BEAM.

It’s more than likely your knowledge of type systems far exceeds mine—I’m frankly not the theory type. My love for them comes from having written code both ways, in C, Python, Lisp, and Haskell. Haskell’s types were such a boon, and it’s not the HM inference at all.

I still suspect the effectiveness of plugging in a type system patch to a complete system, like typescript to javascript. We still observe so many `as any` or `as unknown as` at every corner. Despite of the suspicion, Gleam provides a better and elegant syntax for those who are not familiar with Erlang or functional programming languages, which I loved most.

That doesn’t really apply to Gleam, it’s not a type syntax for another language that can be stripped, it’s its own language that compiles to Erlang and JS

Coming from Elixir, I gave Gleam a try for a couple of days over the holidays. Reasons I decided not to pursue: - No ad-hoc polymorphism (apart from function overloading IIRC) means no standard way of defining how things work. There are not many conventions yet in place so you won’t know if your library supports eg JSON deserialization for its types - Coupled with a lack of macros, this means you have to implement ev…

I’ve been doing Elixir for 9 years, 5 professionally. Nobody cares about ad-hoc polymorphism. The community doesn’t use protocols except “for data”. Whatever that means. Global singleton processes everywhere. I’m really discouraged by the practices I observe but it’s the most enjoyable language for me still.

thought I’d try the showcase example in Raku (https://raku.org), so this Gleam

  import gleam/io

  pub fn main() {
    io.println("hello, friend!")
  }
becomes this Raku

  say “hello, friend!”
well maybe you really want to have a main() so you can pass in name from the command line

  #!/usr/bin/env raku

  sub MAIN($name) {
    say "hello, $name!”
  }

I'd rather them stick with ONE: JS or BEAM. Everytime a project claims it can do multiple things at once, it can't do either very well. It's confusing too. Is Gleam suitable for distributed computing like Elixir/Erlang on BEAM? Would that answer change if I compile it to JS?

Gleam is technically as suitable for distributed computing as Erlang: since it compiles to Erlang, it can do anything that Erlang can. You can use Erlang and Elixir libraries and write FFI code to do things that would be unergonomic to do in Gleam. Sure the experience is different and if you want to embrace the guarantees of static typing, then the APIs will look different, like gleam_otp.

If you compile it to JS, then the guarantees change to JS's guarantees.

Personally I've felt that the JS target is a big plus and hasn't detracted from Gleam. Writing a full stack app with both sides being in Gleam and sharing common code is something I've enjoyed a lot. The most visible impact is that there's no target specific functions in the stdlib or the language itself, so Erlang related things are in gleam_erlang and gleam_otp, and e.g. filesystem access is a package instead of being in the stdlib. If you're just into Erlang, you don't need to interact with the JS target at all.

IMHO this is an education problem.
