Top-level function

aggregateResults :: Aggregator -> [Result] -> ([AggregatedResult], [LogEntry])

Aggregate Results with the given Aggregator. It first groups Results based on its resultFor field, and then each group is aggregated into an AggregatedResult.

If it fails, it returns an empty list of AggregatedResult. It also returns a list of LogEntrys to report warnings and errors.

Aggregators

type Aggregator = NonEmpty Version -> VersionRange

Aggregate some Versions into a VersionRange.

showVersionRange :: VersionRange -> String

Let Cabal convert VersionRange to String

aggOr :: Aggregator

Aggregator of ORed versions.

aggPvpMajor :: Aggregator

Aggregate versions to the range that the versions cover in a PVP sense. This aggregator sets the upper bound to a major version, which means it assumes major-version bump is not backward-compatible.

aggPvpMinor :: Aggregator

Aggregate versions to the range that versions cover in a PVP sense. This aggregator sets the upper bound to a minor version, which means it assumes minor-version bump is not backward-compatible.

Utility

groupAllPreservingOrderBy

Arguments

:: (a -> a -> Bool)

The comparator that determines if the two elements are in the same group. This comparator must be transitive, like '(==)'.

-> [a]

-> [NonEmpty a]

Low-level functions

aggregatePackageVersions

Arguments

:: Aggregator

-> NonEmpty (String, [(PackageName, Maybe Version)])

(label, version map). label is used for error logs.

-> (Maybe [(PackageName, Maybe VersionRange)], [LogEntry])

Aggregate one or more maps between PackageName and Version.

The input Maybe Versions should all be Just. Nothing version is warned and ignored. If the input versions are all Nothing, the result version range is Nothing.

The PackageName lists in the input must be consistent (i.e. they all must be the same list.) If not, it returns Nothing map and an error is logged.
