Hix.Managed.Bump.Candidates

Documentation

isBump :: Version -> Maybe Version -> Bool

We only want to report a bump if the new version actually changes the build.

candidatesBump :: BuildHandlers -> QueryDep -> M (Maybe (DepMutation Bump))

Decide whether the latest version of a dependency requires changes to the currently specified bound.

If no latest version can be found, we return Nothing to indicate that the dep should be skipped.

Otherwise, the range field of the DepMutation is determined:

If the specified dependency has no upper bound (e.g. because the user has only entered the package name and ran the app to resolve the bounds), or if the latest version is outside of the existing bounds, then we add a new bound to the managed state, so we extend the version range by setting the upper bound to the major prefix of the next-highest major of the latest version and return NewBounds.

Otherwise, we return OldBounds.
