This requires a more recent version of `haskell-ci` that supports GHC 9.10.1. Another change that this more recent version of `haskell-ci` introduces is that it drops support for pre-20.04 versions of Ubuntu, so we must also upgrade to a more recent version of Ubuntu (I chose Ubuntu 22.04, or Jammy Jellyfish). Unfortunately, `haskell-ci`'s GHCJS support no longer works with recent versions of Ubuntu (see haskell-CI/haskell-ci#723), so I had to remove the GHCJS configuration from the CI. This does not mean that `singletons` is dropping JavaScript support, however, as we still plan to support building the `singletons` library with GHC's JavaScript backend (the modern successor to GHCJS). There is currently no way to set up a GHC JavaScript backend CI job using `haskell-ci`, and the amount of setup required to manually create one is such that I'm putting it off for now. If someone asks for it, we can add one later.

As you notice in the comments that there's GHC's JS backend on the horizon. Eventually I'd like to support it too, so for time being I'd just leave GHCJS stuff as it is and wait to see how GHC's JS backend shapes up. For sure we cannot use the same "compiler identifier" for JS backend, and we'll have figure out what to do when we know better. So I don't want to cleanup GHCJS stuff for now. EDIT: in perfect world GHC JS backend would just work when corresponding GHC works (i.e. it's more of an arch/os i.e. macos vs linux vs windows or x86 vs arm, than anything else), but I don't see that happening from the beginning. EDIT: there is "is" macos support too, which doesn't work either, there are leftovers which don't work. I'm not too eager to cleanup them, they didn't add maintenance burden so far. |

Sounds good to me. I'll retitle this issue to track explicitly supporting GHC's JavaScript backend. |

Currently,
haskell-cirelies on this GHCJS Ubuntu PPA in order to offer installation support for GHCJS. However, this PPA has not been updated since Ubuntu 18.04, and the minimum version of Ubuntu thathaskell-cinow supports is Focal Fossa (20.04). As such, attempting to install GHCJS viahaskell-ciwill always fail (see this CI job for an example).Perhaps
haskell-cishould just remove its GHCJS support to avoid this potential footgun?The text was updated successfully, but these errors were encountered:
