The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

There is No “Tooling Issue” in Haskell
Significant effort is going into resolving this issue right now and things should be much improved in 9.6. We already have https://errors.haskell.org/ which catalogues many errors with descriptions and examples. The asspciated error codes will be added to all errors once 9.6 is release for easy reference.

[ANN] GHCup-0.1.19.0 released
We're also delighted to announce integration with errors.haskell.org, which already has a couple of GHCup codes documented, e.g. https://errors.haskell.org/messages/GHCup-00010/

[ANN] First release candidate for stack-2.9.3
To support the Haskell Foundation’s Haskell Error Index initiative, all Stack error messages generated by Stack itself begin with an unique code in the form [S-nnnn], where nnnn is a four-digit number.

What prevents Haskell from having good error messages?
I don't think the resolved issues are actually ones about error messages. They largely seem to be meta issues about the project. As far as I know nothing that project has done has made it into a released GHC yet, but GHC 9.6 will have unique error codes for each error pointing to an entry on https://errors.haskell.org/. Both the codes and the website are achievements of that project, specifically under its error-messages-index incarnation. If you'd like to contribute you may like to read https://github.com/haskellfoundation/error-message-index/blob/main/CONTRIBUTING.md or post a message introducing yourself on https://github.com/haskell/error-messages/issues/new.

The Spinnaker Programming Language
String is a linked list of UTF-32 codepoints, which is just as bad as it sounds. Haskell programmers usually use Text from the text package instead.

[ANN] GHCup-0.1.19.0 released
This is the first release that was executed via the new GitHub CI. Everything went smoothly, except for an unexpected packaging bug on windows due to text-2.0 linking against libstdc++ by default.

Limits of possible performance improvements of Haskell/GHC code?
In addition to what's mentioned, the "default" libraries people use are often not the best-performing ones. E.g. Data.Vector.Hashtables is often much faster than Data.HashMap.Strict (which again is typically faster than Data.Map). And we find performance papercuts in common libraries that may simply be due to not enough people optimising for speed.

What is the idiomatic way to test "hidden" module functions in a Cabal project
Used by nearly every Haskell project: https://hackage.haskell.org/package/text 60% of the modules are ".Internal".

Switch internal representation to UTF8 by Bodigrim · Pull Request #365 · haskell/text
Here is a representative patch for text: https://github.com/haskell/text/pull/365/commits/37a2157245457a287d638bbceb472fe93b71f224 Hopefully it clarifies why achieving C performance is problematic even if you have enough primitive operations.

Can I wait forever without getLine?
I want to run an app in a Docker container, but detached. This causes getLine to throw an EOF exception, since the terminal detaches. That is, if I understand this thread correctly https://github.com/haskell/text/issues/258.
What are some alternatives?
When comparing error-message-index and text you can also consider the following projects:
pantry
attempt - Concrete data type for handling extensible exceptions as failures.
haskell-mode - Emacs mode for Haskell
base58string - Bitcoin script compilation, manipulation and decompilation
ghci-dap - ghci having DAP interface.
algebraic-classes - Conversions between algebraic classes and F-algebras.
error-messages
text-ansi
debug-adapter-protocol - Defines a common protocol for debug adapters.
text-trie - An efficient finite map from Text to values, based on bytestring-trie.
ghcup-hs - THIS REPO IS A MIRROR, BUG REPORTS GO HERE:
gps2htmlReport - Generates a HTML page report detailing a GPS journey, with charts, statistics and an OpenStreetMap graphic.
