| Summary: Semigroupoids: Category sans id | |
Provides a wide array of (semi)groupoids and operations for working with them. A 'Semigroupoid' is a 'Category' without the requirement of identity arrows for every object in the category. A 'Category' is any 'Semigroupoid' for which the Yoneda lemma holds. When working with comonads you often have the '<*>' portion of an 'Applicative', but not the 'pure'. This was captured in Uustalu and Vene's "Essence of Dataflow Programming" in the form of the 'ComonadZip' class in the days before 'Applicative'. Apply provides a weaker invariant, but for the comonads used for data flow programming (found in the streams package), this invariant is preserved. Applicative function composition forms a semigroupoid. Similarly many structures are nearly a comonad, but not quite, for instance lists provide a reasonable 'extend' operation in the form of 'tails', but do not always contain a value. Ideally the following relationships would hold: > Foldable ----> Traversable <--- Functor ------> Alt ---------> Plus Semigroupoid > | | | | | > v v v v v > Foldable1 ---> Traversable1 Apply --------> Applicative -> Alternative Category > | | | | > v v v v > Bind ---------> Monad -------> MonadPlus Arrow > Apply, Bind, and Extend (not shown) give rise the Static, Kleisli and Cokleisli semigroupoids respectively. This lets us remove many of the restrictions from various monad transformers as in many cases the binding operation or '<*>' operation does not require them. Finally, to work with these weaker structures it is beneficial to have containers that can provide stronger guarantees about their contents, so versions of 'Traversable' and 'Foldable' that can be folded with just a 'Semigroup' are added.

* Mon Jan 04 2021 psimons@suse.com
- Update semigroupoids to version 5.3.5.
5.3.5 [2020.12.31]
- -----------------
* The build-type has been changed from `Custom` to `Simple`.
To achieve this, the `doctests` test suite has been removed in favor of using
[`cabal-docspec`](https://github.com/phadej/cabal-extras/tree/master/cabal-docspec)
to run the doctests.
* Explicitly mark modules as `Safe`.

5.3.2 [2019.01.04]
- -----------------
* Bump the lower bound on `semigroups` to 0.16.2, and avoid incurring
the dependency entirely on recent GHCs.
* Fix the build on GHC 7.0 and 7.2.

and update copyright headers with spec-cleaner.
* Fri Jul 13 2018 psimons@suse.com
- Update semigroupoids to version 5.3.1.
* Fix a regression introduced in `semigroupoids-5.3` in which some modules
regressed from `Trustworthy` to `Unsafe`.
* Allow building with `containers-0.6`.
* Add `Alt` instances for `First` and `Last` from `Data.Semigroup`, and
`Alt` and `Plus` instances for `First` and `Last` from `Data.Monoid`.
* Add missing `Apply`, `Bind`, `Extend`, `Foldable1` and `Traversable1`
instances for `Data.Semigroups`, `Data.Monoid` and `GHC.Generics`.
* Mon May 14 2018 psimons@suse.com
- Update semigroupoids to version 5.2.2 revision 3.
* Add `optional` to `Data.Functor.Alt` (analogous to the `optional` function
in `Control.Applicative`)
* `liftF2` is now a class method of `Apply` (mirroring the fact that `liftA2`
is now a class method of `Applicative`). `liftF2` and `(<.>)` have default
definitions in terms of the other.
* Allow building with GHC 8.4
* `Apply` and `Bind` instances for `Q`, from the `template-haskell` package.
* Add instances for `(:~:)` and `(:~~:)` from `Data.Type.Equality`, and
`Coercion` from `Data.Type.Coercion`
* Add the `toNonEmpty` method to `Foldable1`. Add `foldrM1` and `foldlM1`
functions to `Data.Semigroup.Foldable` that are defined in terms of `toNonEmpty`.
* Add `Apply`, `Bind`, `Foldable1`, and `Traversable1` instances for `Complex`
* Add `Apply` and `Bind` instances for `HashMap` from the `unordered-containers` package
(on which `semigroupoids` now depends)
* Add `Semigroupoid` instances for `Tagged` and `Const`
