Easily create a new project for a new Cabal package in my new IDE for Haskell (and Agda & Swift). Interested in taking it for a spin? DM me your email for a beta test invite! #Haskell

Just released version 1.6.0 of ‘ProjectNavigator’ — a cross-platform file navigator for SwiftUI based on ‘NavigationSplitView’: https://github.com/mchakravarty/ProjectNavigator

Chatkontrolle: Wir haben eine vier-seitige Zusammenfassung des 200-seitigen Gesetzentwurfs von Dänemark erhalten. "Da uns die realisierbaren Optionen ausgehen", legen sie einfach den alten Vorschlag nochmal vor. Sie fordern explizit "Client-Side-Scanning". data.consilium.europa.eu/doc/document...

The Call for the 2026 International Symposium on Functional and Logic Programming (FLOPS) is open - the symposium will be May 26-28 in Akita, Japan. Deadline for the CfP is Dec 8 (abstracts) / Dec 16 (submissions).
Send us your best on the best of both worlds!

I already hinted at it a few times. I’m building a new development environment for macOS. The current focus is on Haskell support, but it can also do Agda & Swift. I only just started beta testing with external testers, so there are still rough edges. Interested in giving the beta a spin? Send a DM!

The abstract deadline for FProPer is coming up in a bit more than two weeks (31/5 - paper deadline 14/6). If you're working in the space, please consider submitting! And of course, if you know anyone doing interesting work in this area, please also encourage them to submit!

Summer School on Advanced Functional Programming in Utrecht (NL) in July: http://afp.school/

I'm honored to chair - with @gckeller.bsky.social and Sven-Bodo Scholz - FProPer’25, the Workshop on Functional Programming for Productivity and Performance.
CfP asks for full papers (abstract deadline May 31) or standalone abstracts (Aug 2) - hope you'll submit!

If you're working on (high)performance for declarative languages - consider submitting your paper or abstract to FProPer (formerly FHPNC) this year!

📢Programming Languages folks in Lisbon: We're hosting PL@LX this Thursday (Jan 23rd) afternoon in Campo Grande. Details at lasige.pt/talk/program....

Speaking of pearls, we also have Backhouse, Guttmann and Winter's pearl, showing a neat example of a goal-directed, calculational proof: constructing an equivalence relation from a given relation by way of a starth root construction.

Have a read of Shin-Cheng Mu's beautiful functional pearl on deriving an algorithm for bottom-up computation using trees of sublists.

My keynote from FProPer'24 is also online now
