To anyone writing programs in #Scheme right now, this is just a reminder that you can search through a huge cluster of Scheme libraries indexed by procedure name, including all SRFIs, at the https://index.scheme.org/ website. If you need code to do something, try searching by keyword to see if someone has already written it. Most APIs listed there even have Haskell-like types and are tagged as "pure" if they are pure.
I've been trying to make this work for a few days and finally I achieved it, the most basic form of a wayland client using unix sockets, and well in other languages it was not difficult at all, I did it in hare, c, typescript (deno), and in the end I wanted to try with a language that I had never used, Haskell, and I learned many things but I still don't know what a monod is, anyway, here I leave a link to the code for those who are interested: https://gitlab.com/-/snippets/3711372 #haskell#programming#wayland
Shorter feedback cycles for contributors and higher quality of releases, these are a few of our favourite things about the Haddock documentation generation tool coming home to the GHC repository.
how the hell do you add dependencies in Haskell stack, I add yesod to the build-depends in the cabal file like shown in the stack example but on running stack build it fails saying it couldn't find yesod, and then the line is removed from the cabal file. Haskell ecosystem is hell.
usually, it is used to define methods, but in function arguments, it serves as syntactic sugar so you don't have to name generic types... but in a return type, it has a meaning that is slightly different, and actually expresses a semantic not even vanilla haskell can represent!
basically, instead of being able to return any type implementing a trait, it states that it can return at least one type that implements a trait.
in haskell terminology, specifying a generic type parameter is "forall a", while returning an "impl" is "exists a".
The GHC developers are very pleased to announce the release of GHC 9.10.1! 🎉
On the menu:
→ GHC2024 language edition
→ Linear let and where
bindings
→ Annotation of exceptions with backtraces
→ Required type arguments for functions
→ Javascript FFI support in the WebAssembly backend
… and many more!
Between the continued iteration on the GHC20xx meta-extension mechanisms, further improvements in the JS/wasm backends, and (my favorite) the availability of exception backtraces in base, there is lots in this release to be excited about.
See the Haskell Discourse thread for the full announcement:
If like me, you use ghcup tui, and constantly find yourself pressing "u" thinking it means "use" only to find it means "uninstall", you can change the keybindings by editing ~/.ghcup/config.yaml
On Wednesday, 2024-05-15, at 1830 UTC, we'll stream the 25th episode of the #Haskell#Unfolder. This episode should be interesting for Haskellers and non-Haskellers alike. Edsko and I will translate a #gRPC server from #Java to Haskell, contrasting the programming paradigms.
