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.
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.4 projects | reddit.com/r/ProgrammingLanguages | 17 Nov 2021
While her eff is still under construction, there are relative more mature pieces like Koka etc. I'd very much like to understand how her concerns map to those other effect systems, but can't find more write-ups about the design space of effect systems.
Languages that don't support Error-Catching as a Control Structure?
1 project | reddit.com/r/ProgrammingLanguages | 22 Oct 2021
There are a few languages that have algebraic effect systems, most notably Haskell, but these systems are implemented as libraries, not baked into the language (which can have advantages and disadvantages).
The Problem of Effects (2020)
5 projects | news.ycombinator.com | 27 Aug 2021
Let me tell you what I'm worried about with effects systems: One of the smartest people I know of has a library called Eff https://github.com/hasura/eff that efficiently implements effects through some modifications to GHC. The thing is, she's pretty much stopped working on because she found some really nasty semantic edge-cases that she couldn't resolve to her satisfaction. (I don't understand the problems well enough to describe them, and I think they're specific to lazy languages, but it has left me cautious about the effect model in general.)
Thoughts on polysemy?
1 project | reddit.com/r/haskell | 26 Jul 2021
eff was supposed to solve (some of) the above problems, but it's stalled now.
A solid GUI Framework for Haskell?

Why do you need a GUI library, if you can write your application using extensible effects frameworks, just choose any and enjoy!

It means that you can see a type signature like this and you know immediately how it will provide what you want in the context of an arbitrary monad "stack." It means that when you are looking to understand how to use e.g. MegaParsec it doesn't surprise you that the discussion of the relevant monads is the first thing in the tutorial. It means you know why this exists https://hackage.haskell.org/package/scotty-0.12/docs/Web-Scotty-Trans.html and maybe you can even fumble through https://docs.servant.dev/en/stable/cookbook/hoist-server-with-context/HoistServerWithContext.html and use it in your app even if you don't otherwise understand all the type-level magic happening in Servant. You'll also understand what to do if you're faced with a type signature in IO or Maybe or whatever concrete monad and you have to integrate it with a more generalized monad. You may also start to understand why everyone is so interested in effect systems.
Eff - a functional programming language based on algebraic effect handlers
1 project | reddit.com/r/ProgrammingLanguages | 20 Feb 2021
Great to see it's actively developed. And curious to see how it races with https://github.com/hasura/eff
Haskell compiled onto LLVM increase performance?
4 projects | reddit.com/r/haskell | 2 Nov 2021
The other source of haskell documentation is hackage, which features both libraries and higher-level GHC modules. Using hoogle (!hoogle or !hgl in DDG), you can search these docs by module name, function name, or even type signature.
Question about Maybe Types
1 project | reddit.com/r/haskell | 30 Oct 2021
BTW: there's actually a site https://hoogle.haskell.org/ which helps you search functions based on your type signature. If you try it out you might see some of the ones mentioned here
Hoogle – Haskell API search engine

Is there a way to use filter function with an IO Bolean?
1 project | reddit.com/r/haskellquestions | 17 Sep 2021
Hoogle is an excellent resource for this kind of queries, as it makes it possible to search for a function matching a type signature.
Why type systems matter
1 project | dev.to | 26 Aug 2021
Yeah, if the language's ecosystem is tightly integrated with the underlying type system, amazing things are possible, from simple type signature lookups at your fingertips to full-blown type signature search engines like Hoogle and Serokell's hackage-search. Conversely, if the language ecosystem evolved independently from type system, such as TypeScript and Dialyzer extending their respective languages with success typings, likely, self-documenting benefits and improved discoverability will be way less pronounced, if at all.
Stack Overflow Developer Survey 2021 with little Haskell presence
1 project | reddit.com/r/haskell | 4 Aug 2021
If Haskell community is really using Stackoverflow less than general programming populace, then my hypothesis is: for some people using Haskell, most answers can be gotten by asking the right questions to Hoogle.
Hoogle for Rust?

Is there a Rust equivalent to https://hoogle.haskell.org/ ?
What is your opinion on haskell remaining as unpopular?
5 projects | reddit.com/r/haskell | 25 Jul 2021
Hackage has quick jump for searching within packages, and there is hoogle for searching API's globally (all stackage packages) and hackage search for searching code snippets. I think most use cases are covered by those.

at last shell.nix describes that nix-shell can start from inside the same environment that th compilation one. It is from here you could put hoogle and haskell-language-server if needed.
Is there any dictionary of FP algorithms and common higher order funcions?
1 project | reddit.com/r/functionalprogramming | 26 Jun 2021
Doesn't answer your question but, if you can dream up the type signature for a HOF and you want to see if it exists as a predefined function in some common Haskell library or the stdlib, you can use Hoogle. It's useful more often than you think!
