Rebuild Haskell dependencies in Gentoo.

haskell-updater rebuilds Haskell packages on Gentoo after a GHC upgrade or a dependency upgrade. haskell-updater is written so as to use only GHC's boot libraries so as to have no external dependencies.

haskell-updater

Rebuilds Haskell packages on Gentoo after a GHC upgrade or a dependency upgrade.

Updating Haskell packages

Sometimes:

emerge -auvDN --keep-going @world

has trouble figuring out how to update Haskell packages. Providing emerge with the full list of dev-haskell packages that have upgrades available can sometimes help:

emerge -avu --oneshot --keep-going --with-bdeps=y @world
haskell-updater -- --verbose-conflicts

Sometimes we have sub-slot blockers (when updating ghc or some specific package there are a list of blockers). Subslot blockers are a portage limitation (bug).

To find solution use larger --backtrack= with emerge and haskell-updater.

Experimental portage invocation

If you run into errors where haskell-updater tries to reinstall a masked or unavailable package, try haskell-updater --mode=reinstall-atoms or haskell-updater --world. If you find any bugs, report them to the bug tracker.
