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.
[ANNOUNCE] GHC 9.6.1 is now available
2 projects | reddit.com/r/haskell | 12 Mar 2023
There are also a few subtle issues that arise with delconts related to semantics of higher order effects (see here and here), but they might be solvable.

Looking for languages that combine algebraic effects with parallel execution
4 projects | reddit.com/r/ProgrammingLanguages | 25 Oct 2022
You'll get fearless parallel with STM in the mixture, and GHC is getting a work in progress effect system for Haskell, as Delimited continuation primops has been merged.
Should I pick up OCaml or Haskell?
3 projects | reddit.com/r/functionalprogramming | 24 Aug 2022
My last example is algebraic effects, some of which have been made possible in a both practical and efficient way thanks to extremely recent research, and that I can use to implement architectures like Ports and Adapters or Clean Architecture and have very maintainable code. (Extensible Effects — An Alternative to Monad Transformers was published in 2013, Effect Handlers in Scope was published in 2014 and they are behind Polysemy, while there is ongoing work on effects with even better performance, like Eff)
[ANN] cleff - fast and consise extensible effects

cleff's Eff monad is esentially implemented as a ReaderT IO. [...] This is first done by eff, [...]
Opinions on Reader + Continuation-based IO?

Here is link number 1 - Previous text "eff"3 projects | reddit.com/r/haskell | 1 Dec 2021
This is essentially how continuation based effect systems work, check out eveff and eff.
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.
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.)

Any open source projects to contribute to for beginners
8 projects | reddit.com/r/haskell | 13 Feb 2023
You could contribute to IHP! We have some great docs to get started here https://github.com/digitallyinduced/ihp/blob/master/CONTRIBUTING.md And we have some low hanging fruits in GitHub issues for you to get started with, e.g. https://github.com/digitallyinduced/ihp/issues/1601 (also there's always lots of activity in the IHP Slack, in case you have any questions/need help)

Show HN: IHP v1.0 (Batteries-included web framework built on Haskell and Nix)
3 projects | news.ycombinator.com | 24 Oct 2022
Really happy we've finally go to the 1.0 status :) If you like to take a look at the code, check our GitHub at https://github.com/digitallyinduced/ihp
Is there an Elm like framework for cross-platform apps?
7 projects | reddit.com/r/functionalprogramming | 21 Oct 2022
kinda early for running roc in production perhaps, but you can try out haskell and its frameworks like ihp or some other web / mobile / multiplatform framework.
Why Haskell Is Interesting?
4 projects | news.ycombinator.com | 4 Sep 2022
In recent years the Haskell ecosystem has drastically improved.
With Haskell Language Server (HLS) there's now great autocompletion and inline error reporting for e.g. VSCode and other editors.
We've recently got dot-notation, so you can type `myRecord.myField` instead of `myField myRecord`, which makes Haskell code feel more familiar when switching from other languages.
With IHP we now even have a Haskell version of Rails/Laravel. Check it out here: https://ihp.digitallyinduced.com/ (I'm founder of IHP)
Functional Reactive Programming
9 projects | news.ycombinator.com | 16 Aug 2022
Yes, it's possible to build a traditional web company with Haskell. We've made IHP exactly for that :) It's like Rails/Django but for Haskell. https://ihp.digitallyinduced.com/ We specifically try to be batteries-includes (like rails), so you don't have to think too much about what libraries to use, the core of IHP can get you very far without needing to manually decide between libraries.
IHP even won a G2 badge, which is kind of funny and ironic for a Haskell project :D https://www.g2.com/products/ihp/reviews
GHC 9.4.1 is now available
6 projects | news.ycombinator.com | 12 Aug 2022
Thanks to reintroduction of deep subsumption we could finally update IHP to the GHC 9 series. So really happy about the recent GHC releases :)
If you're curious about Haskell, IHP is a good starting point (https://ihp.digitallyinduced.com/ https://github.com/digitallyinduced/ihp). IHP is Haskell's version of Laravel/Rails/Django. It's really a superpower to have Haskell's type system combined with the rapid development approach of Rails :) (Disclaimer: I'm founder of the company that makes IHP)
Web development in Haskell
7 projects | reddit.com/r/haskell | 9 Aug 2022
Check out IHP. Compared to Yesod it's a bit more opinionated. This might be a useful, as it allows you to focus on your domain problem instead of picking libraries etc. Also we have a very active Slack community with over 350 Haskellers. If you have any questions, you can always get help on slack.7 projects | reddit.com/r/haskell | 9 Aug 2022
IHP might be worth checking out. It's very batteries-included, a little like Ruby on Rails. It has very good developer tooling too, imo. It does encourage you to write some kind of non-standard Haskell, but it's minor enough that it's not a big deal.
