Changelog of @hackage/gambler 0.4.1.0

0.4.1.0 (2023-03-09)

Will (..) and Vitality (..) are now re-exported from Fold.Shortcut and Fold.ShortcutNonempty; previously these were only available from Fold.Shortcut.Type and Fold.ShortcutNonempty.Type.

A new utility repeatedly has been added to Fold.Pure, Fold.Nonempty, Fold.Shortcut, and Fold.ShortcutNonempty.

New utilities motivate, premap, and withVitality and a new type alias Vitality' have been added to Fold.Shortcut and Fold.ShortcutNonempty.

0.4.0.0 (2023-03-08)

Changed ShortcutFold from

data ShortcutFold a b = forall x y. ShortcutFold
    { initial     :: Vitality x y
    , step        :: y -> a -> Vitality x y
    , extractDead :: x -> b
    , extractLive :: y -> b }

to

data ShortcutFold a b = forall x y. ShortcutFold
    { initial :: Vitality x y
    , step    :: y -> a -> Vitality x y
    , extract :: Vitality x y -> b }

Changed ShortcutNonemptyFold from

data ShortcutNonemptyFold a b = forall x y. ShortcutNonemptyFold
    { initial     :: a -> Vitality x y
    , step        :: y -> a -> Vitality x y
    , extractDead :: x -> b
    , extractLive :: y -> b }

to

data ShortcutNonemptyFold a b = forall x y. ShortcutNonemptyFold
    { initial :: a -> Vitality x y
    , step    :: y -> a -> Vitality x y
    , extract :: Vitality x y -> b }

Added Fold.Shortcut.duplicate and Fold.ShortcutNonempty.duplicate.

(The type changes make the duplicate functions possible.)

0.3.0.0 (2023-03-07)

In the Fold.ShortcutNonempty module, the type of list and reverseList has changed from ShortcutNonemptyFold a [a] to ShortcutNonemptyFold a (NonEmpty a).

0.2.0.0 (2023-02-22)

The "Examples" modules are no longer divided into "Interesting" and "Boring" modules in the public API, because this leads to too many breaking releases.

NonemptyFold and ShortcutNonemptyFold now have their own sum and product definitions instead of being lifted variants of the Fold and ShortcutFold definitions. This makes it possible to use them with numeric types that do not include additive or multiplicative identity values. For example, we now have a test case which takes the sum over a non-empty list of positive integers. Since a "positive integer" type does not include zero, previously this would result in arithmetic underflow.

0.1.0.0 (2023-02-20)

Adds ShortcutFold and ShortcutNonemptyFold.

The following have changed from Fold to ShortcutFold: and, or, all, any, element, notElement, find, lookup, index, findIndex, elementIndex, null.

first has changed from NonemptyFold to ShortcutNonemptyFold.

0.0.1.0 (2023-02-20)
