- Update lens to version 5.1 revision 1.
Upstream has revised the Cabal build instructions on Hackage.
-------------------------------------------------------------------
Tue Nov 16 19:51:10 UTC 2021 - psimons@suse.com
- Update lens to version 5.1.
5.1 [2021.11.15]
----------------
* Allow building with GHC 9.2.
* Drop support for GHC 7.10 and older.
* The type of `_ConP` in `Language.Haskell.TH.Lens` is now
`Prism' Pat (Name, [Type], [Pat])` instead of `Prism' Pat (Name, [Pat])`
when building with `template-haskell-2.18` or later.
* Define `_CharTyLit` in `Language.Haskell.TH.Lens` when building with
`template-haskell-2.18` or later.
* Add `Prefixed` and `Suffixed` classes to `Control.Lens.Prism`, which provide
`prefixed` and `suffixed` prisms for prefixes and suffixes of sequence types.
These classes generalize the `prefixed` and `suffixed` functions in
`Data.List.Lens`, which were previously top-level functions. In addition to
providing `Prefixed` and `Suffixed` instances for lists, instances for `Text`
and `ByteString` types are also provided.
At present, `Prefixed` and `Suffixed` are re-exported from `Data.List.Lens`
for backwards compatibility. This may change in a future version of `lens`,
however.
* Add a `traversal` function to `Control.Lens.Traversal`. This function, aside
from acting as a `Traversal` counterpart to the `lens` and `prism` functions,
provides documentation on how to define `Traversal`s.
* Add a `matching'` function to `Control.Lens.Prism`. `matching'` is like
`matching`, but with a slightly more general type signature that allows it to
work with combinations of `Lens`es, `Prism`s, and `Traversal`s.

- Update lens to version 5.0.1 revision 1.
Upstream has revised the Cabal build instructions on Hackage.
-------------------------------------------------------------------
Wed Feb 24 18:57:20 UTC 2021 - psimons@suse.com
- Update lens to version 5.0.1.
5.0.1 [2021.02.24]
------------------
* Fix a bug in which `makeLenses` could produce ill kinded optics for
poly-kinded datatypes in certain situations.
-------------------------------------------------------------------
Fri Feb 19 23:03:14 UTC 2021 - psimons@suse.com
- Update lens to version 5.
5 [2021.02.17]
--------------
* Support building with GHC 9.0.
* Remove the `Swapped` type class in favor of `Swap` from the `assoc` package.
* Remove the `Strict` type class in favor of `Strict` from the `strict` package.
The `swapped`, `strict` and `lazy` isomorphisms are now defined using "new" type classes.
Users which define own instances of old type classes are advised to
define instances of the new ones.
```haskell
import qualified Data.Bifunctor.Swap as Swap
import qualified Control.Lens as Lens
instance Swap.Swap MyType where
swap = ...
#if !MIN_VERSION_lens(4,20,0)
instance Lens.Swapped MyType where
swapped = iso Swap.swap Swap.swap
#endif
```
* The `FunctorWithIndex`, `FoldableWithIndex` and `TraversableWithIndex` type classes
have been migrated to a new package,
[`indexed-traversable`](https://hackage.haskell.org/package/indexed-traversable).
The `imapped`, `ifolded` and `itraversed` methods are now top-level functions.
If you are not defining these methods in your instances,
you don't need to change your definitions.
Beware: the `optics-core` package (versions <0.4) defines similar classes,
and will also migrate to use `indexed-traversable` classes. Therefore, you
might get duplicate instance errors if your package defines both.
If you define your own `FunctorWithIndex` etc. instances,
we recommend that you depend directly on the `indexed-traversable` package.
If you want to continue support `lens-4` users, you may write
```haskell
-- from indexed-traversable
import Data.Functor.WithIndex
-- from lens
import qualified Control.Lens as L
-- your (indexed) container
data MySeq a = ...
-- indexed-traversable instance
instance FunctorWithIndex Int MySeq where imap = ...
instance FoldableWithIndex Int MySeq where ifoldMap = ...
instance TraversableWithIndex Int MySeq where itraverse = ...
-- lens <5 instance, note the !
#if !MIN_VERSION_lens(5,0,0)
instance L.FunctorWithIndex Int MySeq where imap = imap
instance L.FoldableWithIndex Int MySeq where ifoldMap = ifoldMap
instance L.TraversableWithIndex Int MySeq where itraverse = itraverse
#endif
```
In other words, always provide `indexed-traversable` instances.
If your package depends on `lens` and allows `lens-4`,
you should additionally provide instances for `lens-4` type classes
that can reuse the `indexed-traversable` instances.
* Make the functions in `Control.Lens.TH` work more robustly with poly-kinded
data types. This can cause a breaking change under certain situations:
* TH-generated optics for poly-kinded data types are now much more likely to
mention kind variables in their definitions, which will require enabling
the `PolyKinds` extension at use sites in order to typecheck.
* Because TH-generated optics now quantify more kind variables than they did
previously, this can affect the order of visible type applications.
* Generalize the types of `generic` and `generic1` to allow type-changing
updates. If you wish to use the old, more restricted types of these
functions, use `simple . generic` or `simple . generic1` instead.
* Add `Control.Lens.Profunctor` with conversion functions to and from
profunctor optic representation.
* Add `Control.Lens.Review.reviewing`, which is like `review` but with a more
polymorphic type.
* Mark `Control.Lens.Equality` as Trustworthy.
* 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.
* Use `alterF` in `At (HashMap k)` instance implementation.
* Use `alterF` in `At` and `Contains` instances for `Set`, `IntSet`, and
`HashSet`.
* Avoid re-inserting keys already present in `ix` for `Set`, `IntSet`,
and `HashSet`. For `Set` and `HashSet`, this changes the semantics
slightly; if the user-supplied key is `==` to one already present in
the set, then the latter will not be replaced in the result.
* Consume `()` values lazily in `Control.Lens.At`.

Fri Nov 8 16:14:07 UTC 2019 - Peter Simons <psimons@suse.com>
- Drop obsolete group attributes.
-------------------------------------------------------------------
Sat Sep 14 02:03:25 UTC 2019 - psimons@suse.com
- Update lens to version 4.18.1.
4.18.1 [2019.09.13]
-------------------
* Remove the use of `cpp-options: -traditional`. This should be unnecessary
on all versions of GHC that `lens` supports, as modern GHCs already use
`-traditional` internally during preprocessing. More critically, the use
of `cpp-options: -traditional` breaks profiling builds on GHC 8.8
(see https://gitlab.haskell.org/ghc/ghc/issues/17185).
