Haskell IDE IHP on immutable KDE Linux

Whoa!

Got my favourite Haskell IDE up and running in an Arch Linux container under the new #kapsule container manager of KDE LINUX

λ IHP: Integrated Haskell Platform

Productive, Type-Safe and Fun!
IHP is a modern batteries-included Web Framework, built on top of Haskell and Nix.

IHP builds upon Determinate Nix, which I could not install in immutable KDE Linux. Having tried other container managers to no avail – while I must admit, that I am not experienced in that domain – … with new #kapsule it can be installed following IHP Guide with just two additional dependencies:

profile add nixpkgs#direnv
profile add nixpkgs#gnumake
