Jan Mas Rovira 13f64afbc1 upgrade to Ghc 9.8.1 (#2624) ... This PR updates the stackage LTS resolver to `nightly-2024-02-06` which uses GHC 9.8.1 ## Upgrade notes You will need to update your HLS to [2.6.0.0](https://github.com/haskell/haskell-language-server/releases/tag/2.6.0.0), this release contains support for GHC 9.8.1 ## Fixes ### `haskeline` / `repline` We have removed the custom haskeline / repline forks used in the build. This is because we had trouble overriding haskeline as it is bundled with GHC and the stackage resolver uses this bundled version. We were using a custom fork of haskeline to implement [mapInputT_](15c0685c91/app/Commands/Repl.hs (L409)) in the Juvix REPL, required to implement error handling. This requires private API from the Haskeline library. Instead of using a custom fork we use TemplateHaskell to obtain access to the private API we need. See [DarkArts.hs](15c0685c91/src/Juvix/Prelude/DarkArts.hs) and [HaskelineJB.hs](15c0685c91/app/HaskelineJH.hs). To obtain access to the private API, we adapted a method from [a Tweag blogpost](https://www.tweag.io/blog/2021-01-07-haskell-dark-arts-part-i/) and [repo](https://github.com/tweag/th-jailbreak) - updating it for GHC 9.8.1. ### `aeson-better-errors` The `aeson-better-errors` library has not been updated to work with `mtl-2.3.0` so it cannot work with the new stackage resolver. We are using a [fork](https://github.com/Vekhir/aeson-better-errors.git) which has been updated. We should consider replacing this library in future, see https://github.com/anoma/juvix/issues/2621 ### `path` The `path` library now includes API `splitDrive` and `dropDrive` so we can remove our versions of those functions from the prelude. ### `with-utf8` We no longer need to depend on `with-utf8`. We were using this package for UTF-8 versions of `readFile` and `writeFile` APIs. These APIs are now available in the `text` package. ### Compiler warnings GHC 9.8.1 introduces several new compiler warnings. * We have suppressed `missing-role-annotations` and `missing-poly-kind-signatures` * We added our own versions of `head` and `tail` to work around the new `partial-tx` warning introduced for those functions in `Data.List`. * We fixed up the code to avoid the [term-variable-capture](https://ghc.gitlab.haskell.org/ghc/doc/users_guide/using-warnings.html#ghc-flag--Wterm-variable-capture) warning.		2024-02-07 09:47:48 +00:00
