Branch: CURRENT, Version: 0.19.1nb1, Package name: hs-semigroups-0.19.1nb1, Maintainer: pho

In mathematics, a semigroup is an algebraic structure consisting of a set
together with an associative binary operation. A semigroup generalizes a
monoid in that there might not exist an identity element. It also
(originally) generalized a group (a monoid with all inverses) to a type
where every element did not have to have an inverse, thus the name
semigroup.

Log message:
hs-*: add PLIST files

These PLIST files have been autogenerated by mk/haskell.mk using
HS_UPDATE_PLIST=yes during a bulk build.  They will help to track changes
to the packages.  The Haskell packages didn't have PLIST files because
their paths contained package hashes.  These hashes are now determined by
mk/haskell.mk, which makes it easy to generate easy to read PLIST files.

Log message:
Update to semigroups-0.19.1

0.19.1 [2019.08.27]
* Add GenericSemigroupMonoid, an adapter newtype suitable for
  DerivingVia, to Data.Semigroup.Generic.
* Work around a bug related to the backported Generic(1) instances in
  this package (that could only be triggered on GHC 7.2 or 7.4) in
  which the hand-written Datatype, Constructor, and Selector instances
  for internal data types could overlap with GHC-generated instances.

0.19 [2019.05.10]
* The (<>) method of the backported Semigroup class no longer has a
  default implementation in terms of mappend. This mirrors the
  Data.Semigroup API that was introduced in base-4.9. This is a
  breaking change for any Semigroup instances that are defined in
  tandem with versions of base older than 4.9.
* Make the backported Hashable Arg instance reflect its respective
  variants in the hashable package. In hashable-1.3, the Hashable Arg
  instance only hashes the first argument, lest equal values have
  different hashes.
* Backport the Lift (NonEmpty a) instance introduced in
  template-haskell-2.15.0.0.
* Data.List.NonEmpty is now unconditionally Trustworthy.

0.18.5 [2018.07.02]
* Use a more efficient sconcat for the Semigroup instances for strict
  and lazy ByteString.

0.18.4 [2018.01.29]
* Backport Semigroup instances for Data.Ord.Down and strict ST, which
  were added in base-4.11.

0.18.3
* Add Semigroup instance for IO, as well as for Event and Lifetime
  from GHC.Event
* Add Eq1, Ord1, Read1, and Show1 instances for NonEmpty
* Define Generic and Generic1 instances back to GHC 7.2, and expose
  the Data.Semigroup.Generic module on GHC 7.2

0.18.2
* Depend on the bytestring-builder package to ensure Semigroup
  instances for bytestring Builder and ShortByteString are always
  defined
* Allow building with binary-0.8.3 and later

0.18.1
* Add the missing instance for Data.Binary.Builder.Builder.

0.18.0.1
* Added support for base-4.9

0.18
* Removed the partial functions words, unwords, lines, unlines

0.17.0.1
* Fixed the @since annotations

0.17
* Added groupWith, groupAllWith, groupWith1, groupAllWith1
* Renamed sortOn to sortWith to match the "Comprehensive
  comprehensions" paper and TransformListComp extension.
* Add Semigroup instances for Alt, Void, Proxy and Tagged
* Add Num instances for Min and Max
* Removed times1p in favor of stimes.

0.16.2.2
* Cleaned up imports to remove warnings on GHC 7.10.

0.16.2.1
* Restored the ability to build on GHC < 7.6. (Generic1 deriving was only \ 
added in GHC 7.6)

0.16.2
* Added genericMappend and supporting GSemigroup class for generically
  deriving Semigroup instances.
* Added Arg a b which only compares for equality/order on its first
  argument, which can be used to compute argmin and argmax.
* Add Bifunctor Arg instance to avoid orphans for GHC 7.10+.
* Added missing Data.Monoid.Generic module to source control.

0.16.1
* Added Semigroup instances for various Builder constructions in text
  and bytestring where available.
* Added MonadFix and MonadPlus instances for NonEmpty.

0.16.0.1
* Bumped deepseq version bound for GHC 7.10 compatibility.

0.16
* times1p and timesN are now reduced to accepting only a Natural
  argument. Whole doesn't exist in GHC 7.10's Numeric.Natural, and
  nats version 1 has removed support for the class.

0.15.4
* Use Data.Coerce.coerce on GHC 7.8+ to reduce the number of
  eta-expansions in the resulting core.
* Avoid conflict with pending Foldable.length in base.
