Is anyone using quickspec?

It looks like that change is on github, but the version wasn't bumped, nor was it pushed to hackage https://github.com/nick8325/quickspec/blob/master/quickspec.cabal Perhaps try using github as the source instead of hackage?
Reverse of quickspec

Quickspec (https://github.com/nick8325/quickspec) is awesome in discovering laws in the code we write. But I am in search for a tool (the reverse) , which given the spec, can it synthesise code ?

Ask HN: Is writing a math proof like programming without ever running your code?
3 projects | news.ycombinator.com | 27 Apr 2023

Quickcheck is a Haskell testing library which allows the programmer to write propositions about how a function should behave, and the library will try to find cases which falsify the proposition.
If my understanding is correct, it can't "prove" any properties, only disprove them.
For concretely proving properties of a program, you would need something like Idris's dependent type system, where you can prove that a function always returns a sorted list, for example.
