Hi everyone, I am proud to release the first version of text-display¹, a typeclass for user-facing output. `Display` is a typeclass that doesn't abide by the rules of `Show` & `Read`, and brings with it a nice and ergonomic way to derive instances through `DerivingVia` when they already have a `Show` instance: ```haskell {-# LANGUAGE DerivingVia #-} data AutomaticallyDerived = AD -- We derive 'Show' deriving Show -- We take advantage of the 'Show' instance to derive 'Display' from it deriving Display via (ShowInstance AutomaticallyDerived) ``` But let's say you want to redact an instance of `Display`? You can do it locally, through the `OpaqueInstance` helper. It is most useful to hide tokens or passwords: ```haskell data UserToken = UserToken UUID deriving Display via (OpaqueInstance "[REDACTED]" UserToken) display $ UserToken "7a01d2ce-31ff-11ec-8c10-5405db82c3cd" -- => "[REDACTED]" ``` I hope you will have fun with this library! Cheers! ¹ https://hackage.haskell.org/package/text-display-0.0.1.0 -- Hécate ✨ 🐦: @TechnoEmpress IRC: Hecate WWW: https://glitchbra.in RUN: BSD
