Applicative Code

Applicative Code has got a blog! And with it, a first article sketching the concept behind the IDE. https://blog.applicative.co/a/3mmteyfxgoo23-developing-functional-code

This is going to come in handy for the Haskell-support in Applicative Code: www.well-typed.com/blog/2026/09...

New release of the code editor component used in Applicative Code.

Next upcoming beta feature: support for multiple sets of toolchains

When a shiny new version of GHC comes out, it should be easy to upgrade. After all, the new compiler should be more capable than the previous version! “Making GHC upgrades easy” on the #Haskell Blog, by Simon Peyton-Jones blog.haskell.org/making-ghc-u...

This addition is crucial for the external folder feature coming to Applicative Code projects.

#Haskell Language Server 2.14 release announcement: blog.haskell.org/hls-2-14-0-0/ Quality of life improvements, bug fixes, and what is to expect for this year's Google Summer of Code!

Applicative Code uses this package for its project navigator.

‘ProjectNavigator’ is a SwiftUI package for a versatile file tree-based project navigation view for macOS and iOS. It just hit version 1.8.0, getting support for symbolic links: https://github.com/mchakravarty/ProjectNavigator

Applicative Code comes with a companion app: the Toolchain Manager. It helps you configure toolchains for use with Applicative Code. And it enables Applicative Code to use those toolchains — after all, Applicative Code is fully sandboxed.

Applicative Code also supports Agda. (More Agda functionality is forthcoming.)

The project navigator (left hand-side of the window) of Applicative Code is also available as a open-source Swift package: https://github.com/mchakravarty/ProjectNavigator

Did you know that the code editor component of Applicative Code is available as an open-source Swift package? https://github.com/mchakravarty/CodeEditorView/ #swift #haskell

Welcome to Applicative Code!

Are you interested in a new Haskell IDE for macOS? I’m looking for beta testers! Send me a DM with your email for a TestFlight invitation.

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
