Methods

ifoldMap :: Monoid m => (i -> a -> m) -> f a -> m #

Fold a container by mapping value to an arbitrary Monoid with access to the index i.

When you don't need access to the index then foldMap is more flexible in what it accepts.

foldMap ≡ ifoldMap . const

ifoldMap' :: Monoid m => (i -> a -> m) -> f a -> m #

A variant of ifoldMap that is strict in the accumulator.

When you don't need access to the index then foldMap' is more flexible in what it accepts.

foldMap' ≡ ifoldMap' . const

ifoldr :: (i -> a -> b -> b) -> b -> f a -> b #

Right-associative fold of an indexed container with access to the index i.

When you don't need access to the index then foldr is more flexible in what it accepts.

foldr ≡ ifoldr . const

ifoldl :: (i -> b -> a -> b) -> b -> f a -> b #

Left-associative fold of an indexed container with access to the index i.

When you don't need access to the index then foldl is more flexible in what it accepts.

foldl ≡ ifoldl . const

ifoldr' :: (i -> a -> b -> b) -> b -> f a -> b #

Strictly fold right over the elements of a structure with access to the index i.

When you don't need access to the index then foldr' is more flexible in what it accepts.

foldr' ≡ ifoldr' . const

ifoldl' :: (i -> b -> a -> b) -> b -> f a -> b #

Fold over the elements of a structure with an index, associating to the left, but strictly.

When you don't need access to the index then foldlOf' is more flexible in what it accepts.

foldl' l ≡ ifoldl' l . const

class (MonadState s m, MonadState t n) => Zoom (m :: Type -> Type) (n :: Type -> Type) s t | m -> s, n -> t, m t -> n, n s -> m where #

This class allows us to zoom in, changing the State supplied by many different monad transformers, potentially quite deep in a monad transformer stack.

Its functions can be used to run a monadic action in a larger State than it was defined in, using a Lens', an AffineTraversal' or a Traversal'.

This is commonly used to lift actions in a simpler State Monad into a State Monad with a larger State type.

When used with a Traversal' over multiple values, the actions for each target are executed sequentially and the results are aggregated.

This can be used to edit pretty much any Monad transformer stack with a State in it!

>>> flip L.evalState ('a','b') $ zoom _1 $ use equality
'a'

>>> flip S.execState ('a','b') $ zoom _1 $ equality .= 'c'
('c','b')

>>> flip L.execState [(1,2),(3,4)] $ zoomMany traversed $ _2 %= (*10)
[(1,20),(3,40)]

>>> flip S.runState [('a',"b"),('c',"d")] $ zoomMany traversed $ _2 <%= (\x -> x <> x)
("bbdd",[('a',"bb"),('c',"dd")])

>>> flip S.evalState ("a","b") $ zoomMany each (use equality)
"ab"

type Prism' s a = Optic' A_Prism NoIx s a #

Type synonym for a type-preserving prism.

type Lens' s a = Optic' A_Lens NoIx s a #

Type synonym for a type-preserving lens.

type Optic' k (is :: IxList) s a = Optic k is s s a a #

Common special case of Optic where source and target types are equal.

Here, we need only one "big" and one "small" type. For lenses, this means that in the restricted form we cannot do type-changing updates.

data Optic k (is :: IxList) s t a b #

Wrapper newtype for the whole family of optics.

The first parameter k identifies the particular optic kind (e.g. A_Lens or A_Traversal).

The parameter is is a list of types available as indices. This will typically be NoIx for unindexed optics, or WithIx for optics with a single index. See the "Indexed optics" section of the overview documentation in the Optics module of the main optics package for more details.

The parameters s and t represent the "big" structure, whereas a and b represent the "small" structure.

class (MonadReader b m, MonadReader a n) => Magnify (m :: Type -> Type) (n :: Type -> Type) b a | m -> b, n -> a, m a -> n, n b -> m where #

This class allows us to magnify part of the environment, changing the environment supplied by many different Monad transformers. Unlike zoom this can change the environment of a deeply nested Monad transformer.

Its functions can be used to run a monadic action in a larger environment than it was defined in, using a Getter or an AffineFold.

They act like local, but can in many cases change the type of the environment as well.

They're commonly used to lift actions in a simpler Reader Monad into a Monad with a larger environment type.

They can be used to edit pretty much any Monad transformer stack with an environment in it:

>>> (1,2) & magnify _2 (+1)
3

>>> flip runReader (1,2) $ magnify _1 ask
1

>>> flip runReader (1,2,[10..20]) $ magnifyMaybe (_3 % _tail) ask

class (Ixed m, IxKind m ~ An_AffineTraversal) => At m where #

At provides a Lens that can be used to read, write or delete the value associated with a key in a Map-like container on an ad hoc basis.

An instance of At should satisfy:

ix k ≡ at k % _Just

Methods

at :: Index m -> Lens' m (Maybe (IxValue m)) #

>>> Map.fromList [(1,"world")] ^. at 1
Just "world"

>>> at 1 ?~ "hello" $ Map.empty
fromList [(1,"hello")]

Note: Usage of this function might introduce space leaks if you're not careful to make sure that values put inside the Just constructor are evaluated. To force the values and avoid such leaks, use at' instead.

Note: Map-like containers form a reasonable instance, but not Array-like ones, where you cannot satisfy the Lens laws.

Associated Types

type IxKind m #

Type family that takes a key-value container type and returns the kind of optic to index into it. For most containers, it's An_AffineTraversal, Representable (Naperian) containers it is A_Lens, and multi-maps would have A_Traversal.

type IxKind m = An_AffineTraversal

Methods

ix :: Index m -> Optic' (IxKind m) NoIx m (IxValue m) #

NB: Setting the value of this AffineTraversal will only set the value in at if it is already present.

If you want to be able to insert missing values, you want at.

class Is k l #

Subtyping relationship between kinds of optics.

An instance of Is k l means that any Optic k can be used as an Optic l. For example, we have an Is A_Lens A_Traversal instance, but not Is A_Traversal A_Lens.

This class needs instances for all possible combinations of tags.

Type synonym for a type-preserving van Laarhoven affine traversal.

type AffineTraversalVL s t a b = forall (f :: Type -> Type). Functor f => (forall r. r -> f r) -> (a -> f b) -> s -> f t #

Type synonym for a type-modifying van Laarhoven affine traversal.

Note: this isn't exactly van Laarhoven representation as there is no Pointed class (which would be a superclass of Applicative that contains pure but not <*>). You can interpret the first argument as a dictionary of Pointed that supplies the point function (i.e. the implementation of pure).

A TraversalVL has Applicative available and hence can combine the effects arising from multiple elements using <*>. In contrast, an AffineTraversalVL has no way to combine effects from multiple elements, so it must act on at most one element. (It can act on none at all thanks to the availability of point.)

Class for read-write optics that have their read-only counterparts.

Associated Types

type ReadOnlyOptic k #

Methods

getting :: forall (is :: IxList). Optic k is s t a b -> Optic' (ReadOnlyOptic k) is s a #

Turn read-write optic into its read-only counterpart (or leave read-only optics as-is).

This is useful when you have an optic :: Optic k is s t a b of read-write kind k such that s, t, a, b are rigid, there is no evidence that s ~ t and a ~ b and you want to pass optic to one of the functions that accept read-only optic kinds.

Example:

>>> let fstIntToChar = _1 :: Lens (Int, r) (Char, r) Int Char

>>> :t view fstIntToChar
...
...Couldn't match type ‘Char’ with ‘Int’

class ViewableOptic k r where #

Generalized view (even more powerful than view from the lens library).

View the value(s) pointed to by an optic.

The type of the result depends on the optic. You get:

Exactly one result a with Iso, Lens, ReversedPrism and Getter.
At most one result Maybe a with Prism, AffineTraversal and AffineFold.
Monoidal summary of all results Monoid a => a with Traversal and Fold.

When in doubt, use specific, flavour restricted versions. This function is mostly useful for things such as passthrough.

class Generic a => GenericLabelOptics a #

If the explicit-generic-labels Cabal flag is enabled, only types with this instance (which can be trivially derived with DeriveAnyClass extension) will be able to use labels as generic optics with a specific type.

It's an option for application developers to disable implicit fallback to generic optics for more control.

Libraries using generic labels with their data types should derive this instance for compatibility with the explicit-generic-labels flag.

Note: the flag explicit-generic-labels is disabled by default. Enabling it is generally unsupported as it might lead to compilation errors of dependencies relying on implicit fallback to generic optics.

Since: optics-core-0.4

Associated Types

type HasGenericLabelOptics a :: Bool #

type HasGenericLabelOptics a = 'True

type family HasGenericLabelOptics a :: Bool #

type LabelOptic' (name :: Symbol) k s a = LabelOptic name k s s a a #

Type synonym for a type-preserving optic as overloaded label.

class LabelOptic (name :: Symbol) k s t a b | name s -> k a, name t -> k b, name s b -> t, name t a -> s where #

Support for overloaded labels as optics.

An overloaded label #foo can be used as an optic if there is an instance LabelOptic "foo" k s t a b.

Alternatively, if both s and t have a Generic (GenericLabelOptics if explicit-generic-labels flag is enabled) instance, a total field of s is accessible by a label #field of kind A_Lens, whereas its constructor by a label #_Constructor of kind A_Prism.

Methods

labelOptic :: Optic k NoIx s t a b #

Used to interpret overloaded label syntax. An overloaded label #foo corresponds to labelOptic @"foo".

Instances

Instances details

(k ~ An_Iso, a ~ Void0, b ~ Void0) => LabelOptic name k Void0 Void0 a b	If for an overloaded label `#label` there is no instance starting with `LabelOptic "label"` in scope, using it in the context of optics makes GHC immediately pick the overlappable instance defined below (since no other instance could match). If at this point GHC has no information about `s` or `t`, it ends up picking incoherent instance of `GenericLabelOptic` defined below. Prevent that (if only to be able to inspect most polymorphic types of `#foo % #bar` or `view #foo` in GHCi) by defining a dummy instance that matches all names, thus postponing instance resolution until `s` or `t` is known.

simple :: Iso' a a #

Proof of reflexivity.

equality :: (s ~ a, t ~ b) => Iso s t a b #

Capture type constraints as an isomorphism.

Note: This is the identity optic:

>>> :t view equality
view equality :: a -> a

equality' :: Lens a b a b #

Strict version of equality.

Useful for strictifying optics with lazy (irrefutable) pattern matching by precomposition, e.g.

_1' = equality' % _1

iso :: (s -> a) -> (b -> t) -> Iso s t a b #

Build an iso from a pair of inverse functions.

If you want to build an Iso from the van Laarhoven representation, use isoVL from the optics-vl package.

withIso :: Iso s t a b -> ((s -> a) -> (b -> t) -> r) -> r #

Extract the two components of an isomorphism.

au :: Functor f => Iso s t a b -> ((b -> t) -> f s) -> f a #

Based on ala from Conor McBride's work on Epigram.

This version is generalized to accept any Iso, not just a newtype.

>>> au (coerced1 @Sum) foldMap [1,2,3,4]
10

You may want to think of this combinator as having the following, simpler type:

au :: Iso s t a b -> ((b -> t) -> e -> s) -> e -> a

under :: Iso s t a b -> (t -> s) -> b -> a #

The opposite of working over a Setter is working under an isomorphism.

under ≡ over . re

non :: Eq a => a -> Iso' (Maybe a) a #

If v is an element of a type a, and a' is a sans the element v, then non v is an isomorphism from Maybe a' to a.

non ≡ non' . only

Keep in mind this is only a real isomorphism if you treat the domain as being Maybe (a sans v).

This is practically quite useful when you want to have a Map where all the entries should have non-zero values.

>>> Map.fromList [("hello",1)] & at "hello" % non 0 %~ (+2)
fromList [("hello",3)]

>>> Map.fromList [("hello",1)] & at "hello" % non 0 %~ (subtract 1)
fromList []

>>> Map.fromList [("hello",1)] ^. at "hello" % non 0
1

>>> Map.fromList [] ^. at "hello" % non 0
0

This combinator is also particularly useful when working with nested maps.

e.g. When you want to create the nested Map when it is missing:

>>> Map.empty & at "hello" % non Map.empty % at "world" ?~ "!!!"
fromList [("hello",fromList [("world","!!!")])]

and when have deleting the last entry from the nested Map mean that we should delete its entry from the surrounding one:

>>> Map.fromList [("hello", Map.fromList [("world","!!!")])] & at "hello" % non Map.empty % at "world" .~ Nothing
fromList []

It can also be used in reverse to exclude a given value:

>>> non 0 # rem 10 4
Just 2

>>> non 0 # rem 10 5
Nothing

non' :: Prism' a () -> Iso' (Maybe a) a #

anon :: a -> (a -> Bool) -> Iso' (Maybe a) a #

rewriteOf :: forall k (is :: IxList) a b. Is k A_Setter => Optic k is a b a b -> (b -> Maybe a) -> a -> b #

Rewrite by applying a rule everywhere you can. Ensures that the rule cannot be applied anywhere in the result:

propRewriteOf l r x = all (isNothing . r) (universeOf l (rewriteOf l r x))

A definition of ix for types with an At instance. This is the default if you don't specify a definition for ix.

sans :: At m => Index m -> m -> m #

Delete the value associated with a key in a Map-like container

sans k = at k .~ Nothing

makePrisms #

Arguments

:: Name	Type constructor name
-> DecsQ

Generate a Prism for each constructor of a data type. Isos generated when possible. Reviews are created for constructors with existentially quantified constructors and GADTs.

e.g.

data FooBarBaz a
  = Foo Int
  | Bar a
  | Baz Int Char
makePrisms ''FooBarBaz

will create

_Foo :: Prism' (FooBarBaz a) Int
_Bar :: Prism (FooBarBaz a) (FooBarBaz b) a b
_Baz :: Prism' (FooBarBaz a) (Int, Char)

makeClassyPrisms #

Arguments

:: Name	Type constructor name
-> DecsQ

Generate a Prism for each constructor of a data type and combine them into a single class. No Isos are created. Reviews are created for constructors with existentially quantified constructors and GADTs.

e.g.

data FooBarBaz a
  = Foo Int
  | Bar a
  | Baz Int Char
makeClassyPrisms ''FooBarBaz

will create

class AsFooBarBaz s a | s -> a where
  _FooBarBaz :: Prism' s (FooBarBaz a)
  _Foo :: Prism' s Int
  _Bar :: Prism' s a
  _Baz :: Prism' s (Int,Char)

  _Foo = _FooBarBaz % _Foo
  _Bar = _FooBarBaz % _Bar
  _Baz = _FooBarBaz % _Baz

instance AsFooBarBaz (FooBarBaz a) a

Generate an As class of prisms. Names are selected by prefixing the constructor name with an underscore. Constructors with multiple fields will construct Prisms to tuples of those fields.

simpleLenses :: Lens' LensRules Bool #

Generate "simple" optics even when type-changing optics are possible. (e.g. Lens' instead of Lens)

generateSignatures :: Lens' LensRules Bool #

Indicate whether or not to supply the signatures for the generated lenses.

Disabling this can be useful if you want to provide a more restricted type signature or if you want to supply hand-written haddocks.

generateUpdateableOptics :: Lens' LensRules Bool #

Generate "updateable" optics when True. When False, (affine) folds will be generated instead of (affine) traversals and getters will be generated instead of lenses. This mode is intended to be used for types with invariants which must be maintained by "smart" constructors.

generateLazyPatterns :: Lens' LensRules Bool #

Generate optics using lazy pattern matches. This can allow fields of an undefined value to be initialized with lenses:

data Foo = Foo {_x :: Int, _y :: Bool}
  deriving Show

makeLensesWith (lensRules & generateLazyPatterns .~ True) ''Foo

> undefined & x .~ 8 & y .~ True
Foo {_x = 8, _y = True}

The downside of this flag is that it can lead to space-leaks and code-size/compile-time increases when generated for large records. By default this flag is turned off, and strict optics are generated.

When using lazy optics the strict optic can be recovered by composing with equality':

strictOptic = equality' % lazyOptic

createClass :: Lens' LensRules Bool #

Create the class if the constructor if generated lenses would be type-preserving and the lensClass rule matches.

lensField :: Lens' LensRules FieldNamer #

Lens' to access the convention for naming fields in our LensRules.

lensClass :: Lens' LensRules ClassyNamer #

Lens' to access the option for naming "classy" lenses.

lensRules :: LensRules #

Rules for making read-write field optics as top-level functions. It uses underscoreNoPrefixNamer.

underscoreNoPrefixNamer :: FieldNamer #

lensRulesFor #

Arguments

:: [(String, String)]	(Field name, Optic name)
-> LensRules

Construct a LensRules value for generating top-level functions using the given map from field names to definition names.

lookingupNamer :: [(String, String)] -> FieldNamer #

classyRules :: LensRules #

Rules for making lenses and traversals that precompose another Lens.

classyRules_ :: LensRules #

A LensRules used by makeClassy_.

makeLenses :: Name -> DecsQ #

Build field optics as top level functions with a sensible default configuration.

  = Cat { _age  :: Int
        , _name :: String
        }
  | Dog { _age    :: Int
        , _absurd :: forall a b. a -> b
        }
makeLenses ''Animal

will create

absurd :: forall a b. AffineFold Animal (a -> b)
absurd = afolding $ \s -> case s of
  Cat _ _ -> Nothing
  Dog _ x -> Just x

age :: Lens' Animal Int
age = lensVL $ \f s -> case s of
  Cat x1 x2 -> fmap (\y -> Cat y x2) (f x1)

makeLenses = makeLensesWith lensRules

makeClassy :: Name -> DecsQ #

  fooY = foo % fooY

instance HasFoo Foo where
  foo  = lensVL id
  fooX = lensVL $ \f s -> case s of

  fooY = lensVL $ \f s -> case s of
    Foo x1 x2 -> fmap (\y -> Foo x1 y) (f x2)

makeClassy = makeLensesWith classyRules

makeClassy_ :: Name -> DecsQ #

Make lenses and traversals for a type, and create a class when the type has no arguments. Works the same as makeClassy except that (a) it expects that record field names do not begin with an underscore, (b) all record fields are made into lenses, and (c) the resulting lens is prefixed with an underscore.

makeLensesFor :: [(String, String)] -> Name -> DecsQ #

Derive field optics, specifying explicit pairings of (fieldName, opticName).

If you map multiple fields to the same optic and it is present in the same constructor, Traversal (or Fold for a read only version) will be generated.

e.g.

makeLensesFor [("_foo", "fooLens"), ("baz", "lbaz")] ''Foo
makeLensesFor [("_barX", "bar"), ("_barY", "bar")] ''Bar

makeClassyFor :: String -> String -> [(String, String)] -> Name -> DecsQ #

Derive lenses and traversals, using a named wrapper class, and specifying explicit pairings of (fieldName, traversalName).

Example usage:

makeClassyFor "HasFoo" "foo" [("_foo", "fooLens"), ("bar", "lbar")] ''Foo

makeLensesWith :: LensRules -> Name -> DecsQ #

Build field optics with a custom configuration.

declareLenses :: DecsQ -> DecsQ #

Make field optics for all records in the given declaration quote. All record syntax in the input will be stripped off.

e.g.

declareLenses [d|
  data Foo = Foo { fooX, fooY :: Int }
    deriving Show
  |]

will create

data Foo = Foo Int Int deriving Show
fooX, fooY :: Lens' Foo Int

declareLensesFor :: [(String, String)] -> DecsQ -> DecsQ #

Similar to makeLensesFor, but takes a declaration quote.

declareClassy :: DecsQ -> DecsQ #

For each record in the declaration quote, make lenses and traversals for it, and create a class when the type has no arguments. All record syntax in the input will be stripped off.

e.g.

declareClassy [d|
  data Foo = Foo { fooX, fooY :: Int }
    deriving Show
  |]

will create

data Foo = Foo Int Int deriving Show
class HasFoo t where
  foo :: Lens' t Foo
instance HasFoo Foo where foo = id
fooX, fooY :: HasFoo t => Lens' t Int

declareClassyFor :: [(String, (String, String))] -> [(String, String)] -> DecsQ -> DecsQ #

Similar to makeClassyFor, but takes a declaration quote.

declarePrisms :: DecsQ -> DecsQ #

Generate a Prism for each constructor of each data type.

e.g.

declarePrisms [d|
  data Exp = Lit Int | Var String | Lambda{ bound::String, body::Exp }
  |]

will create

data Exp = Lit Int | Var String | Lambda { bound::String, body::Exp }
_Lit :: Prism' Exp Int
_Var :: Prism' Exp String
_Lambda :: Prism' Exp (String, Exp)

declareFields :: DecsQ -> DecsQ #

 declareFields = declareLensesWith defaultFieldRules

declareLensesWith :: LensRules -> DecsQ -> DecsQ #

declareLenses with custom LensRules.

underscoreFields :: LensRules #

Field rules for fields in the form _prefix_fieldname

underscoreNamer :: FieldNamer #

A FieldNamer for underscoreFields.

camelCaseFields :: LensRules #

Field rules for fields in the form prefixFieldname or _prefixFieldname

If you want all fields to be lensed, then there is no reason to use an _ before the prefix. If any of the record fields leads with an _ then it is assume a field without an _ should not have a lens created.

Note: The prefix must be the same as the typename (with the first letter lowercased). This is a change from lens versions before lens 4.5. If you want the old behaviour, use makeLensesWith abbreviatedFields

camelCaseNamer :: FieldNamer #

A FieldNamer for camelCaseFields.

classUnderscoreNoPrefixFields :: LensRules #

Field rules for fields in the form _fieldname (the leading underscore is mandatory).

Note: The primary difference to camelCaseFields is that for classUnderscoreNoPrefixFields the field names are not expected to be prefixed with the type name. This might be the desired behaviour when the DuplicateRecordFields extension is enabled.

classUnderscoreNoPrefixNamer :: FieldNamer #

A FieldNamer for classUnderscoreNoPrefixFields.

abbreviatedFields :: LensRules #

Field rules fields in the form prefixFieldname or _prefixFieldname If you want all fields to be lensed, then there is no reason to use an _ before the prefix. If any of the record fields leads with an _ then it is assume a field without an _ should not have a lens created.

Note that prefix may be any string of characters that are not uppercase letters. (In particular, it may be arbitrary string of lowercase letters and numbers) This is the behavior that defaultFieldRules had in lens 4.4 and earlier.

abbreviatedNamer :: FieldNamer #

A FieldNamer for abbreviatedFields.

makeFields :: Name -> DecsQ #

Generate overloaded field accessors.

e.g

data Foo a = Foo { _fooX :: Int, _fooY :: a }
newtype Bar = Bar { _barX :: Char }
makeFields ''Foo
makeFields ''Bar

will create

class HasX s a | s -> a where
  x :: Lens' s a

instance HasX (Foo a) Int where
  x = lensVL $ \f s -> case s of
    Foo x1 x2 -> fmap (\y -> Foo y x2) (f x1)

class HasY s a | s -> a where
  y :: Lens' s a

instance HasY (Foo a) a where
  y = lensVL $ \f s -> case s of
    Foo x1 x2 -> fmap (\y -> Foo x1 y) (f x2)

instance HasX Bar Char where
  x = lensVL $ \f s -> case s of
    Bar x1 -> fmap (\y -> Bar y) (f x1)

For details, see camelCaseFields.

makeFields = makeLensesWith defaultFieldRules

makeFieldsNoPrefix :: Name -> DecsQ #

Generate overloaded field accessors based on field names which are only prefixed with an underscore (e.g. _name), not additionally with the type name (e.g. _fooName).

This might be the desired behaviour in case the DuplicateRecordFields language extension is used in order to get rid of the necessity to prefix each field name with the type name.

As an example:

data Foo a  = Foo { _x :: Int, _y :: a }
newtype Bar = Bar { _x :: Char }
makeFieldsNoPrefix ''Foo
makeFieldsNoPrefix ''Bar

will create classes

class HasX s a | s -> a where
  x :: Lens' s a
class HasY s a | s -> a where
  y :: Lens' s a

together with instances

instance HasX (Foo a) Int
instance HasY (Foo a) a where
instance HasX Bar Char where

For details, see classUnderscoreNoPrefixFields.

adjoin :: forall k l (is :: IxList) s a (js :: IxList). (Is k A_Traversal, Is l A_Traversal) => Optic' k is s a -> Optic' l js s a -> Traversal' s a infixr 6 #

Combine two disjoint traversals into one.

>>> over (_1 % _Just `adjoin` _2 % _Right) not (Just True, Right False)
(Just False,Right True)

Note: if the argument traversals are not disjoint, the result will not respect the Traversal laws, because it will visit the same element multiple times. See section 7 of Understanding Idiomatic Traversals Backwards and Forwards by Bird et al. for why this is illegal.

castOptic :: forall destKind srcKind (is :: IxList) s t a b. Is srcKind destKind => Optic srcKind is s t a b -> Optic destKind is s t a b #

Explicit cast from one optic flavour to another.

The resulting optic kind is given in the first type argument, so you can use TypeApplications to set it. For example

 castOptic @A_Lens o

turns o into a Lens.

This is the identity function, modulo some constraint jiggery-pokery.

Compose two optics of the same flavour.

Normally you can simply use (%) instead, but this may be useful to help type inference if the type of one of the optics is otherwise under-constrained.

(%&) :: forall k (is :: IxList) s t a b l (js :: IxList) s' t' a' b'. Optic k is s t a b -> (Optic k is s t a b -> Optic l js s' t' a' b') -> Optic l js s' t' a' b' infixl 9 #

Since: optics-core-0.3

unsafeFiltered :: (a -> Bool) -> AffineTraversal' a a #

Filter result(s) of a traversal that don't satisfy a predicate.

Note: This is not a legal Traversal, unless you are very careful not to invalidate the predicate on the target.

As a counter example, consider that given evens = unsafeFiltered even the second Traversal law is violated:

over evens succ . over evens succ /= over evens (succ . succ)

So, in order for this to qualify as a legal Traversal you can only use it for actions that preserve the result of the predicate!

For a safe variant see indices (or filtered for read-only optics).

isingular :: forall k (is :: IxList) i s a. (Is k A_Traversal, HasSingleIndex is i) => Optic' k is s a -> IxAffineTraversal' i s a #

Combine two disjoint indexed traversals into one.

>>> iover (_1 % itraversed `iadjoin` _2 % itraversed) (+) ([0, 0, 0], (3, 5))

over' :: forall k (is :: IxList) s t a b. Is k A_Setter => Optic k is s t a b -> (a -> b) -> s -> t #

Apply a setter as a modifier, strictly.

TODO DOC: what exactly is the strictness property?

Example:

 f :: Int -> (Int, a) -> (Int, a)
 f k acc
   | k > 0     = f (k - 1) $ over' _1 (+1) acc
   | otherwise = acc

runs in constant space, but would result in a space leak if used with over.

Note that replacing $ with $! or _1 with _1' (which amount to the same thing) doesn't help when over is used, because the first coordinate of a pair is never forced.

makePrismLabels :: Name -> DecsQ #

makeFieldLabelsWith :: LensRules -> Name -> DecsQ #

Build field optics as labels with a custom configuration.

makeFieldLabels :: Name -> DecsQ #

Build field optics as instances of the LabelOptic class for use with overloaded labels. See Optics.Label for how to use this pattern.

e.g.

data Animal
  = Cat { animalAge  :: Int
        , animalName :: String
        }
  | Dog { animalAge    :: Int
        , animalAbsurd :: forall a b. a -> b
        }
makeFieldLabels ''Animal

will create

instance
  (k ~ A_Lens, a ~ Int, b ~ Int
  ) => LabelOptic "age" k Animal Animal a b where
  labelOptic = lensVL $ \f s -> case s of
    Cat x1 x2 -> fmap (\y -> Cat y x2) (f x1)
    Dog x1 x2 -> fmap (\y -> Dog y x2) (f x1)

instance
  (k ~ An_AffineTraversal, a ~ String, b ~ String
  ) => LabelOptic "name" k Animal Animal a b where
  labelOptic = atraversalVL $ \point f s -> case s of
    Cat x1 x2 -> fmap (\y -> Cat x1 y) (f x2)
    Dog x1 x2 -> point (Dog x1 x2)

instance
  ( Dysfunctional "absurd" k Animal Animal a b
  , k ~ An_AffineFold, a ~ (x -> y), b ~ (x -> y)
  ) => LabelOptic "absurd" k Animal Animal a b where
  labelOptic = afolding $ \s -> case s of
    Cat _ _  -> Nothing
    Dog _ f  -> Just f

which can be used as #age, #name and #absurd with the OverloadedLabels language extension.

Note: if you wonder about the structure of instances, see Optics.Label.

makeFieldOptics = makeFieldLabelsWith fieldLabelsRules

makeFieldLabelsNoPrefix :: Name -> DecsQ #

An alias for makeFieldLabels noPrefixFieldLabels.

makeFieldLabelsFor :: [(String, String)] -> Name -> DecsQ #

Derive field optics as labels, specifying explicit pairings of (fieldName, labelName).

If you map multiple fields to the same label and it is present in the same constructor, Traversal (or Fold for a read only version) will be generated.

e.g.

makeFieldLabelsFor [("_foo", "fooLens"), ("baz", "lbaz")] ''Foo
makeFieldLabelsFor [("_barX", "bar"), ("_barY", "bar")] ''Bar

declareFieldLabels :: DecsQ -> DecsQ #

Make field optics as labels for all records in the given declaration quote. All record syntax in the input will be stripped off.

e.g.

declareLenses [d|
  data Dog = Dog { name :: String, age :: Int }
    deriving Show
  |]

will create

data Dog = Dog String Int
  deriving Show
instance (k ~ A_Lens, ...) => LabelOptic "name" k Dog Dog ...
instance (k ~ A_Lens, ...) => LabelOptic "age" k Dog Dog ...

declareFieldLabelsWith :: LensRules -> DecsQ -> DecsQ #

fieldLabelsRules :: LensRules #

Rules for generation of LabelOptic instances for use with OverloadedLabels. Same as lensRules, but uses camelCaseNamer.

Note: if you don't want to prefix field names with the full name of the data type, you can use abbreviatedNamer instead.

fieldLabelsRulesFor #

Arguments

:: [(String, String)]	(Field name, Label name)

Construct a LensRules value for generating LabelOptic instances using the given map from field names to definition names.

noPrefixFieldLabels :: LensRules #

Field rules for fields without any prefix. Useful for generation of field labels when paired with DuplicateRecordFields language extension so that no prefixes for field names are necessary.

class Monad m => MonadError e (m :: Type -> Type) | m -> e #

The strategy of combining computations that can throw exceptions by bypassing bound functions from the point an exception is thrown to the point that it is handled.

Is parameterized over the type of error information and the monad type constructor. It is common to use Either String as the monad type constructor for an error monad in which error descriptions take the form of strings. In that case and many other common cases the resulting monad is already defined as an instance of the MonadError class. You can also define your own error type and/or use a monad type constructor other than Either String or Either IOError. In these cases you will have to explicitly define instances of the MonadError class. (If you are using the deprecated Control.Monad.Error or Control.Monad.Trans.Error, you may also have to define an Error instance.)
