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.
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!
Helsinki Haskell Users Group's first book club had its conclusion meeting today with Sockets and Pipes coming to its very end. It has been a ride, one with plenty of scheduling difficulties, but I think we only fell like a month and a half from the original planned schedule and actually had a member retention rate of 100% (of members who were there in the beginning, sadly we could not quite make it 133%)!
To talk a bit about the book as a whole, I do feel like I understand Monad Transformers a lot better now though I'll still need to reread the sections introducing them I am sure. ReaderT especially was something I could see was colossally handy, but given it was in the second to last chapter we were already quite deep with trying to understand everything else so the true utility of it remains somewhat hazy despite the quality of the chapter itself which felt higher than those surrounding it. The habit of reading RFCs and attempting to match the spec in the types one writes is also one I should include in my general workflow, though that is probably a no-brainer for most. It just wasn't a thing in my previous work, so bear with me while I call it a novel concept!
I'm still working on my personal project, but getting nix-build working seems difficult. I'll just have to bring it up in the next main group Office Hours meetup I suppose, lest I never get this show on the road!
You can always try out #haskell snippets on https://play.haskell.org! Many libraries, like aeson, containers, vector, effectful, text and text-builder-linear, are readily available!
