[ANN] tasty-cache 0.1.0.0
Haskell Community [Unofficial]
April 28, 2026
Hello everyone,
I had AI build me a Nix-inspired, HIE-based, test caching tool:
* GitHub - GitHub - silky/tasty-cache: Cache tests based on their source dependency tree; only re-run when source meaningfully changed. · GitHub
* Hackage - tasty-cache: Tasty ingredient that skips unchanged tests using GHC HIE files
It works by using the HIE files to compute a hash of all the depenencies of a test function, and then decides whether to re-run on that basis.
I tried to explore all the potential failure cases; and of course there’s some ways to disable it entirely.
Very curious to know if you find it useful; and please do report any issues!
