Hello Guix Devs,

I've been using Guix for the last few months. As a Haskell programmer, I realized the latest stable that's available in the guix package repository is 9.2.8 which is _really_ old, considering that the current stable releases are at least older than 9.6.x.

I'd like to contribute to this if I can, since I myself would like to have the latest GHC for my uses.  So, how can I get the latest versions available? Do I need to add every release, or can I just add the most latest?

Also, is the process of adding a GHC release, or any Haskell package any different from the typical procedure to add a package? I'd like some introductory guidance/resources to learn that.

The same is true for rustc, the latest stable release is not updated. I'd like to help with that, if possible.

Let me know with how to proceed, and if there's anything I need to be aware of. Regarding copyright assignment, I've already started the paperwork by emailing the form to assign@gnu.org. I did it through Emacs, but I believe I don't need to do it again? Some guidance for that would also be helpful.

Regards,

Divya Ranjan,

Hello Divya,

I would like to only reply to your last point:

No need to assign copyright for work on Guix, we keep the individual
contributors.

But I may as well comment on the other ones and have myself corrected by more
knowlegeable people from the corresponding teams.

There should not be a difference with packages for other languages.
As far as I know, however, ghc is annoying to bootstrap, and we need at
least the latest x.y.z version to continue to x.(y+2).

For rust, there is a special branch rust-team, where the work is coordinated.

I think you need to add every other major release to the chain. We
already have 9.2 and 9.4, so 9.6 should not be a problem in that regard.

Not really, but this specific update (GHC 9.4 to 9.6) is quite tricky
because GHC changed their build system from a make to Hadrian. Hadrian
written in Haskell and depends on quite many packages, so we need to
build all those with an earlier GHC version to be able to build the
current GHC. See https://issues.guix.gnu.org/67921 for the current
situation with this. I am still quite busy with other things in life, so
feel free to pick those patches up.

The Guix manual[1] and cookbook[2] have generic documentation and examples
for creating Guix packages.

Understood, will keep in mind.

Okay, should I contact them separately or do I need to CC someone specific?

in addition, note that we’re importing packages matching our GHC version
from Stackage where possible and not the latest and greatest from Hackage.

Okay, so GHC needs to be incrementally upgraded, understood.

Indeed, since I’ve done a bit of tinkering with GHC’s source, and have tried building with Hadrian, I’ll see what can be done. Thank you for referring me to the issue, I’ll check.

From the checkout, you can do this:
   ./etc/teams.scm show rust

...
members:
+ Efraim Flashner <efraim@flashner.co.il>

Well, so a team can be one person ;-)
I think Efraim reads this list, but feel free to cc him.

Is there a specific reason why we’re following the Stackage releases? Stackage is one step slower in getting the updates. The current Stackage Nightly is 9.8.2, while Hackage has 9.10.1. Is this due to some stability issues with Hackage?

I've been on a bit of a hiatus with the holidays but they're almost done
so I hope to be more "productive" soon.

I'm currently testing a small bump to librsvg and then I'm going to add
the rust-team branch to the merge queue, which will upgrade the rust
package to 1.81.

Stackage’s package collection is coherent and so we don’t have to
manually deal with and resolve dependency conflicts. (Currently the
Hackage/Stackage importer cannot pick the correct package version for
dependencies when importing or updating a package.)

Another thing to keep in mind is that packaging for development is different than packaging for a distribution. Packaging for a distribution you only want to pull in packages from stackage that are required to build eg. xmonad or shellcheck.

However having robust importing for when those needs / maintenence on those packages arrives, and for using guix to help develop a haskell project would be a good gain. imo focusing attention on the importer(s) and the ability to import from different sources (correctly) would be the problem to tackle.
