@hyperrealgopher Next level would be to combine patterns with guards.But most importantly you should try ViewPatterns extension, this may blow your mind off.P.S. You can remove all the parenthesis you added to the code from your post.

@alice Actually I see this technique of using an empty type class for the first time whereas I’ve seen regular type synonyms with Constraint kind many many times. I think the latest is better since it doesn’t and couldn’t bring anything new while a type class can technically have a lot of different stuff inside, types, functions, values, type families, data families, whatever. You have to look at the class to tell if it’s just a combination of other constraints or something more.

@lnxw37a2 @alex@gleasonator.com @JoYo I think “false bottom” as well as local encryption are even more important.

@hyperrealgopher Within 10 mins:foldl (\acc x -> maybe acc ((acc <>) . pure . fmap (succ . length)) $ uncons x) [] (group "aaaabbbcca")

@hyperrealgopher Within 10 mins:foldl (\acc x -> maybe acc ((acc <>) . pure . fmap (succ . length)) $ uncons x) [] (group "aaaabbbcca")And I wouldn’t use `head` since it’s a partial function.

@commagray nah, “gentah” is not good enough to compete with NixOS, lol.

@hyperrealgopher pay attention for providing stack traces. See for HasCallStack constraint (from GHC.Stack module in “base” package).

@commagray by the way, here is systemd-free #NixOS: https://gitea.redalder.org/Magic_RB/NixNG

@hyperrealgopher pay attention to <nixpkgs>, it’s taken from your local system setup. If you want to have true reproducibility then you would pin it one way or another to a particular commit. You can always ask more questions in #nix:nixos.org (in #Matrix).

@ashwinvis Nix is a really simple language, which suits functional paradigm and laziness perfectly well. I don’t know about Guile and how it works, it’s another language I would have to learn. For me, as a Haskell developer, Nix was pretty intuitive to just read and write, I only had to look for a couple of nuances in the docs. For me personally it’s Guile which would be a barrier to start.

@drq Well, #Nix and #NixOS make it even better. It was never so easy to contribute a package to the repository (which is literally a Git repository). The package gets built automatically and binary cache populated. And the maintenance cost is very low.

@drq Could you describe steps for each you have to go through in order to add a new package to the repository?

@drq > I see somebody using Nix, it's always something isn't workingI only hear this from someone who doesn’t use Nix. For me it’s like a horror you tell kids to make them behave good.For me it was working from the beginning. And it was doing what I wanted (actually I wanted something like Nix for years before I even get to know it exists). And it was working for me for around 2 years already. Since now you saw me, you can remove “always” from your notes.

@drq Oof, that list is big. For Nix and NixOS it is just this:1. Clone the https://github.com/NixOS/nixpkgs2. Write mostly JSON-like config for your app (a random example https://github.com/NixOS/nixpkgs/blob/808a8f52dce6e33270ab00472810687dbcca2eca/pkgs/applications/networking/instant-messengers/psi-plus/default.nix )3. Make a merge request
