Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
Introduction to Doctests in Haskell
6 projects | reddit.com/r/haskell | 19 Apr 2022
Looking for a few projects that make use of it, I found accelerate, hawk, polysemy and pretty-simple, so I'll be interested to poke around in their code and see how they have things set up.
ReaderT pattern is just extensible effects
2 projects | reddit.com/r/haskell | 3 Feb 2022
Right, I think I'll just give it a shot to see. Polysemy is nice but I'm still having trouble getting what I want out of it (which may very well be entirely a fault of my own understanding)
Where's more discussion of the designs of effect systems?
4 projects | reddit.com/r/ProgrammingLanguages | 17 Nov 2021
Languages such as Koka only support algebraic effects, not scoping operations such as catch and listen. The Effect Handlers in Scope paper introduces scoping operations, which lead to the Haskell libraries fused-effects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.

Trouble Reinterpreting Higher Order Effects in PolySemy
1 project | reddit.com/r/haskell | 23 Apr 2021
Looking at the interpreter for Reader might give some clues if this doesn't work. https://github.com/polysemy-research/polysemy/blob/master/src/Polysemy/Reader.hs#L38-L45
Structuring Code with ZIO & ZLayers
3 projects | reddit.com/r/scala | 3 Mar 2021
*But I'm not terribly well versed in Scala's other DI offerings. I came from Haskell and didn't find anything in Scala that clicked with me until I found ZIO. It reminded me a lot of my favorite way of writing Haskell programs (https://github.com/polysemy-research/polysemy)—albeit with a completely different implementation.
LiquidHaskell plugin build failed
I think text-format is abandon, when I checked the LiquidHaskell repo in GitHub it looks like they removed it from the latest un-released version PR#1789.
master should already be GHC 9 ready, it just so it happens that we didn't released it on Hackage due to the fact that, practically speaking, GHC 9.0.2 is not very widely used as I think we had some minor issues, but in principle it should work, at least with cabal: https://github.com/ucsd-progsys/liquidhaskell/blob/develop/cabal.ghc9.project
There is a Could not resolve dependencies problem. (Details are in the github issue👈)
