(<$) :: Functor f => a -> f b -> f a infixl 4 #

Replace all locations in the input with the same value. The default definition is fmap . const, but this may be overridden with a more efficient version.

class Functor f => Applicative (f :: Type -> Type) where #

A functor with application, providing operations to

embed pure expressions (pure), and
sequence computations and combine their results (<*> and liftA2).

A minimal complete definition must include implementations of pure and of either <*> or liftA2. If it defines both, then they must behave the same as their default definitions:

(<*>) = liftA2 id

liftA2 f x y = f <$> x <*> y

Further, any definition must satisfy the following:

identity

pure id <*> v = v

composition

pure (.) <*> u <*> v <*> w = u <*> (v <*> w)

homomorphism

pure f <*> pure x = pure (f x)

interchange

u <*> pure y = pure ($ y) <*> u

The other methods have the following default definitions, which may be overridden with equivalent specialized implementations:

```
u *> v = (id <$ u) <*> v
```
```
u <* v = liftA2 const u v
```

As a consequence of these laws, the Functor instance for f will satisfy

```
fmap f x = pure f <*> x
```

It may be useful to note that supposing

forall x y. p (q x y) = f x . g y

it follows from the above that

liftA2 p (liftA2 q u v) = liftA2 f u . liftA2 g v

If f is also a Monad, it should satisfy

```
pure = return
```
```
(<*>) = ap
```
```
(*>) = (>>)
```

(which implies that pure and <*> satisfy the applicative functor laws).

Minimal complete definition

pure, ((<*>) | liftA2)

Methods

pure :: a -> f a #

Lift a value.

(<*>) :: f (a -> b) -> f a -> f b infixl 4 #

Sequential application.

A few functors support an implementation of <*> that is more efficient than the default one.

liftA2 :: (a -> b -> c) -> f a -> f b -> f c #

Lift a binary function to actions.

Some functors support an implementation of liftA2 that is more efficient than the default one. In particular, if fmap is an expensive operation, it is likely better to use liftA2 than to fmap over the structure and then use <*>.

(*>) :: f a -> f b -> f b infixl 4 #

Sequence actions, discarding the value of the first argument.

(<*) :: f a -> f b -> f a infixl 4 #

Sequence actions, discarding the value of the second argument.

class (Functor t, Foldable t) => Traversable (t :: Type -> Type) where #

Functors representing data structures that can be traversed from left to right.

A definition of traverse must satisfy the following laws:

naturality: t . traverse f = traverse (t . f) for every applicative transformation t
identity: traverse Identity = Identity
composition: traverse (Compose . fmap g . f) = Compose . fmap (traverse g) . traverse f

A definition of sequenceA must satisfy the following laws:

naturality: t . sequenceA = sequenceA . fmap t for every applicative transformation t
identity: sequenceA . fmap Identity = Identity
composition: sequenceA . fmap Compose = Compose . fmap sequenceA . sequenceA

where an applicative transformation is a function

t :: (Applicative f, Applicative g) => f a -> g a

preserving the Applicative operations, i.e.

```
t (pure x) = pure x
```
```
t (x <*> y) = t x <*> t y
```

and the identity functor Identity and composition of functors Compose are defined as

  newtype Identity a = Identity a

  instance Functor Identity where
    fmap f (Identity x) = Identity (f x)

  instance Applicative Identity where
    pure x = Identity x
    Identity f <*> Identity x = Identity (f x)

  newtype Compose f g a = Compose (f (g a))

  instance (Functor f, Functor g) => Functor (Compose f g) where
    fmap f (Compose x) = Compose (fmap (fmap f) x)

  instance (Applicative f, Applicative g) => Applicative (Compose f g) where
    pure x = Compose (pure (pure x))
    Compose f <*> Compose x = Compose ((<*>) <$> f <*> x)

(The naturality law is implied by parametricity.)

Instances are similar to Functor, e.g. given a data type

data Tree a = Empty | Leaf a | Node (Tree a) a (Tree a)

a suitable instance would be

instance Traversable Tree where
   traverse f Empty = pure Empty
   traverse f (Leaf x) = Leaf <$> f x
   traverse f (Node l k r) = Node <$> traverse f l <*> f k <*> traverse f r

This is suitable even for abstract types, as the laws for <*> imply a form of associativity.

The superclass instances should satisfy the following:

In the Functor instance, fmap should be equivalent to traversal with the identity applicative functor (fmapDefault).
In the Foldable instance, foldMap should be equivalent to traversal with a constant applicative functor (foldMapDefault).

Minimal complete definition

traverse | sequenceA

Methods

sconcat :: NonEmpty a -> a #

Reduce a non-empty list with <>

The default definition should be sufficient, but this can be overridden for efficiency.

stimes :: Integral b => b -> a -> a #

Repeat a value n times.

Given that this works on a Semigroup it is allowed to fail if you request 0 or fewer repetitions, and the default definition will do so.

By making this a member of the class, idempotent semigroups and monoids can upgrade this to execute in O(1) by picking stimes = stimesIdempotent or stimes = stimesIdempotentMonoid respectively.

liftA :: Applicative f => (a -> b) -> f a -> f b #

Lift a function to actions. This function may be used as a value for fmap in a Functor instance.

liftA3 :: Applicative f => (a -> b -> c -> d) -> f a -> f b -> f c -> f d #

Lift a ternary function to actions.

(<$>) :: Functor f => (a -> b) -> f a -> f b infixl 4 #

An infix synonym for fmap.

The name of this operator is an allusion to $. Note the similarities between their types:

 ($)  ::              (a -> b) ->   a ->   b
(<$>) :: Functor f => (a -> b) -> f a -> f b

Whereas $ is function application, <$> is function application lifted over a Functor.

Examples

simulate :: Rational -> Active a -> [a] #

simulate r act simulates the Active value act, returning a list of "snapshots" taken at regular intervals from the start time to the end time. The interval used is determined by the rate r, which denotes the "frame rate", that is, the number of snapshots per unit time.

If the Active value is constant (and thus has no start or end times), a list of length 1 is returned, containing the constant value.

discrete :: [a] -> Active a #

Create an Active which takes on each value in the given list in turn during the time [0,1], with each value getting an equal amount of time. In other words, discrete creates a "slide show" that starts at time 0 and ends at time 1. The first element is used prior to time 0, and the last element is used after time 1.

It is an error to call discrete on the empty list.

movie :: [Active a] -> Active a #

Splice together a list of active values using |>>. The list must be nonempty.

(|>>) :: Active a -> Active a -> Active a #

"Splice" two Active values together: shift the second to start immediately after the first (using after), and produce the value which acts like the first up to the common end/start point, then like the second after that. If both are constant, return the first.

(->>) :: Semigroup a => Active a -> Active a -> Active a infixr 5 #

Sequence/overlay two Active values: shift the second to start immediately after the first (using after), then compose them (using <>).

after :: Active a -> Active a -> Active a #

a1 `after` a2 produces an active that behaves like a1 but is shifted to start at the end time of a2. If either a1 or a2 are constant, a1 is returned unchanged.

atTime :: Time Rational -> Active a -> Active a #

atTime t a is an active value with the same behavior as a, shifted so that it starts at time t. If a is constant it is returned unchanged.

setEra :: Era Rational -> Active a -> Active a #

Set the era of an Active value. Note that this will change a constant Active into a dynamic one which happens to have the same value at all times.

trimAfter :: Monoid a => Active a -> Active a #

"Trim" an active value so that it is empty after the end of its era. For example, trimAfter ui can be visualized as

See the documentation of trim for more details.

trimBefore :: Monoid a => Active a -> Active a #

"Trim" an active value so that it is empty before the start of its era. For example, trimBefore ui can be visualized as

See the documentation of trim for more details.

trim :: Monoid a => Active a -> Active a #

"Trim" an active value so that it is empty outside its era. trim has no effect on constant values.

For example, trim ui can be visualized as

Actually, trim ui is not well-typed, since it is not guaranteed that ui's values will be monoidal (and usually they won't be)! But the above image still provides a good intuitive idea of what trim is doing. To make this precise we could consider something like trim (First . Just $ ui).

See also trimBefore and trimActive, which trim only before or after the era, respectively.

clampAfter :: Active a -> Active a #

"Clamp" an active value so that it is constant after the end of its era. For example, clampBefore ui can be visualized as

See the documentation of clamp for more information.

clampBefore :: Active a -> Active a #

"Clamp" an active value so that it is constant before the start of its era. For example, clampBefore ui can be visualized as

See the documentation of clamp for more information.

clamp :: Active a -> Active a #

"Clamp" an active value so that it is constant before and after its era. Before the era, clamp a takes on the value of a at the start of the era. Likewise, after the era, clamp a takes on the value of a at the end of the era. clamp has no effect on constant values.

For example, clamp ui can be visualized as

See also clampBefore and clampAfter, which clamp only before or after the era, respectively.

snapshot :: Time Rational -> Active a -> Active a #

Take a "snapshot" of an active value at a particular time, resulting in a constant value.

backwards :: Active a -> Active a #

Reverse an active value so the start of its era gets mapped to the end and vice versa. For example, backwards ui can be visualized as

shift :: Duration Rational -> Active a -> Active a #

shift d act shifts the start time of act by duration d. Has no effect on constant values.

during :: Active a -> Active a -> Active a #

a1 `during` a2 stretches and shifts a1 so that it has the same era as a2. Has no effect if either of a1 or a2 are constant.

stretchTo :: Duration Rational -> Active a -> Active a #

stretchTo d stretches an Active so it has duration d. Has no effect if (1) d is non-positive, or (2) the Active value is constant, or (3) the Active value has zero duration. [AJG: conditions (1) and (3) no longer true: to consider changing]

stretch :: Rational -> Active a -> Active a #

stretch s act "stretches" the active act so that it takes s times as long (retaining the same start time).

interval :: Fractional a => Time Rational -> Time Rational -> Active a #

interval a b is an active value starting at time a, ending at time b, and taking the value t at time t.

ui :: Fractional a => Active a #

ui represents the unit interval, which takes on the value t at time t, and has as its era [0,1]. It is equivalent to interval 0 1, and can be visualized as follows:

On the x-axis is time, and the value that ui takes on is on the y-axis. The shaded portion represents the era. Note that the value of ui (as with any active) is still defined outside its era, and this can make a difference when it is combined with other active values with different eras. Applying a function with fmap affects all values, both inside and outside the era. To manipulate values outside the era specifically, see clamp and trim.

To alter the values that ui takes on without altering its era, use its Functor and Applicative instances. For example, (*2) <$> ui varies from 0 to 2 over the era [0,1]. To alter the era, you can use stretch or shift.

data Era n #

An Era is a concrete span of time, that is, a pair of times representing the start and end of the era. Eras form a semigroup: the combination of two Eras is the smallest Era which contains both. They do not form a Monoid, since there is no Era which acts as the identity with respect to this combining operation.

Era is abstract. To construct Era values, use mkEra; to deconstruct, use start and end.

A Dynamic a can be thought of as an a value that changes over the course of a particular Era. It's envisioned that Dynamic will be mostly an internal implementation detail and that Active will be most commonly used. But you never know what uses people might find for things.

Instances

Functor Dynamic
Instance details Defined in Data.Active Methods fmap :: (a -> b) -> Dynamic a -> Dynamic b # (<$) :: a -> Dynamic b -> Dynamic a #
Apply Dynamic	`Dynamic` is an instance of `Apply` (i.e. `Applicative` without `pure`): a time-varying function is applied to a time-varying value pointwise; the era of the result is the combination of the function and value eras. Note, however, that `Dynamic` is not an instance of `Applicative` since there is no way to implement `pure`: the era would have to be empty, but there is no such thing as an empty era (that is, `Era` is not an instance of `Monoid`).

Semigroup a => Semigroup (Dynamic a)	`Dynamic a` is a `Semigroup` whenever `a` is: the eras are combined according to their semigroup structure, and the values of type `a` are combined pointwise. Note that `Dynamic a` cannot be an instance of `Monoid` since `Era` is not.

data Active a #

There are two types of Active values:

An Active can simply be a Dynamic, that is, a time-varying value with start and end times.
An Active value can also be a constant: a single value, constant across time, with no start and end times.

The addition of constant values enable Monoid and Applicative instances for Active.

class Contravariant (f :: Type -> Type) where #

The class of contravariant functors.

Whereas in Haskell, one can think of a Functor as containing or producing values, a contravariant functor is a functor that can be thought of as consuming values.

As an example, consider the type of predicate functions a -> Bool. One such predicate might be negative x = x < 0, which classifies integers as to whether they are negative. However, given this predicate, we can re-use it in other situations, providing we have a way to map values to integers. For instance, we can use the negative predicate on a person's bank balance to work out if they are currently overdrawn:

newtype Predicate a = Predicate { getPredicate :: a -> Bool }

instance Contravariant Predicate where
  contramap f (Predicate p) = Predicate (p . f)
                                         |   `- First, map the input...
                                         `----- then apply the predicate.

overdrawn :: Predicate Person
overdrawn = contramap personBankBalance negative

Any instance should be subject to the following laws:

contramap id = id
contramap f . contramap g = contramap (g . f)

Note, that the second law follows from the free theorem of the type of contramap and the first law, so you need only check that the former condition holds.

newtype Option a #

Option is effectively Maybe with a better instance of Monoid, built off of an underlying Semigroup instead of an underlying Monoid.

Ideally, this type would not exist at all and we would just fix the Monoid instance of Maybe.

In GHC 8.4 and higher, the Monoid instance for Maybe has been corrected to lift a Semigroup instance instead of a Monoid instance. Consequently, this type is no longer useful. It will be marked deprecated in GHC 8.8 and removed in GHC 8.10.

class Bifunctor (p :: Type -> Type -> Type) where #

A bifunctor is a type constructor that takes two type arguments and is a functor in both arguments. That is, unlike with Functor, a type constructor such as Either does not need to be partially applied for a Bifunctor instance, and the methods in this class permit mapping functions over the Left value or the Right value, or both at the same time.

Formally, the class Bifunctor represents a bifunctor from Hask -> Hask.

Intuitively it is a bifunctor where both the first and second arguments are covariant.

You can define a Bifunctor by either defining bimap or by defining both first and second.

If you supply bimap, you should ensure that:

bimap id id ≡ id

If you supply first and second, ensure:

first id ≡ id
second id ≡ id

If you supply both, you should also ensure:

bimap f g ≡ first f . second g

These ensure by parametricity:

bimap  (f . g) (h . i) ≡ bimap f h . bimap g i
first  (f . g) ≡ first  f . first  g
second (f . g) ≡ second f . second g

Since: base-4.8.0.0

Minimal complete definition

bimap | first, second

Methods

bimap :: (a -> b) -> (c -> d) -> p a c -> p b d #

Map over both arguments at the same time.

bimap f g ≡ first f . second g

Examples

Expand

>>> bimap toUpper (+1) ('j', 3)
('J',4)

>>> bimap toUpper (+1) (Left 'j')
Left 'J'

>>> bimap toUpper (+1) (Right 3)
Right 4

This is a valid definition of stimes for a Monoid.

Unlike the default definition of stimes, it is defined for 0 and so it should be preferred where possible.

This is a valid definition of stimes for an idempotent Semigroup.

When x <> x = x, this definition should be preferred, because it works in O(1) rather than O(log n).

alphaChannel :: AlphaColour a -> a #

Returns the opacity of an AlphaColour.

blend :: (Num a, AffineSpace f) => a -> f a -> f a -> f a #

Compute the weighted average of two points. e.g.

blend 0.4 a b = 0.4*a + 0.6*b

The weight can be negative, or greater than 1.0; however, be aware that non-convex combinations may lead to out of gamut colours.

withOpacity :: Num a => Colour a -> a -> AlphaColour a #

Creates an AlphaColour from a Colour with a given opacity.

c `withOpacity` o == dissolve o (opaque c)

dissolve :: Num a => a -> AlphaColour a -> AlphaColour a #

Returns an AlphaColour more transparent by a factor of o.

opaque :: Num a => Colour a -> AlphaColour a #

Creates an opaque AlphaColour from a Colour.

alphaColourConvert :: (Fractional b, Real a) => AlphaColour a -> AlphaColour b #

Change the type used to represent the colour coordinates.

transparent :: Num a => AlphaColour a #

This AlphaColour is entirely transparent and has no associated colour channel.

black :: Num a => Colour a #

colourConvert :: (Fractional b, Real a) => Colour a -> Colour b #

Change the type used to represent the colour coordinates.

data Colour a #

This type represents the human preception of colour. The a parameter is a numeric type used internally for the representation.

The Monoid instance allows one to add colours, but beware that adding colours can take you out of gamut. Consider using blend whenever possible.

renderDia :: (Backend b v n, HasLinearMap v, Metric v, Typeable n, OrderedField n, Monoid' m) => b -> Options b v n -> QDiagram b v n m -> Result b v n #

Render a diagram.

renderDiaT :: (Backend b v n, HasLinearMap v, Metric v, Typeable n, OrderedField n, Monoid' m) => b -> Options b v n -> QDiagram b v n m -> (Transformation v n, Result b v n) #

Render a diagram, returning also the transformation which was used to convert the diagram from its ("global") coordinate system into the output coordinate system. The inverse of this transformation can be used, for example, to convert output/screen coordinates back into diagram coordinates. See also adjustDia.

lookupSub :: IsName nm => nm -> SubMap b v n m -> Maybe [Subdiagram b v n m] #

Look for the given name in a name map, returning a list of subdiagrams associated with that name. If no names match the given name exactly, return all the subdiagrams associated with names of which the given name is a suffix.

rememberAs :: IsName a => a -> QDiagram b v n m -> SubMap b v n m -> SubMap b v n m #

Add a name/diagram association to a submap.

Construct a SubMap from a list of associations between names and subdiagrams.

rawSub :: Subdiagram b v n m -> QDiagram b v n m #

Extract the "raw" content of a subdiagram, by throwing away the context.

getSub :: (Metric v, OrderedField n, Semigroup m) => Subdiagram b v n m -> QDiagram b v n m #

Turn a subdiagram into a normal diagram, including the enclosing context. Concretely, a subdiagram is a pair of (1) a diagram and (2) a "context" consisting of an extra transformation and attributes. getSub simply applies the transformation and attributes to the diagram to get the corresponding "top-level" diagram.

location :: (Additive v, Num n) => Subdiagram b v n m -> Point v n #

Get the location of a subdiagram; that is, the location of its local origin with respect to the vector space of its parent diagram. In other words, the point where its local origin "ended up".

subPoint :: (Metric v, OrderedField n) => Point v n -> Subdiagram b v n m #

Create a "point subdiagram", that is, a pointDiagram (with no content and a point envelope) treated as a subdiagram with local origin at the given point. Note this is not the same as mkSubdiagram . pointDiagram, which would result in a subdiagram with local origin at the parent origin, rather than at the given point.

mkSubdiagram :: QDiagram b v n m -> Subdiagram b v n m #

Turn a diagram into a subdiagram with no accumulated context.

atop :: (OrderedField n, Metric v, Semigroup m) => QDiagram b v n m -> QDiagram b v n m -> QDiagram b v n m infixl 6 #

A convenient synonym for mappend on diagrams, designed to be used infix (to help remember which diagram goes on top of which when combining them, namely, the first on top of the second).

mkQD :: Prim b v n -> Envelope v n -> Trace v n -> SubMap b v n m -> Query v n m -> QDiagram b v n m #

Create a diagram from a single primitive, along with an envelope, trace, subdiagram map, and query function.

query :: Monoid m => QDiagram b v n m -> Query v n m #

Get the query function associated with a diagram.

localize :: (Metric v, OrderedField n, Semigroup m) => QDiagram b v n m -> QDiagram b v n m #

"Localize" a diagram by hiding all the names, so they are no longer visible to the outside.

withNames :: (IsName nm, Metric v, Semigroup m, OrderedField n) => [nm] -> ([Subdiagram b v n m] -> QDiagram b v n m -> QDiagram b v n m) -> QDiagram b v n m -> QDiagram b v n m #

Given a list of names and a diagram transformation indexed by a list of subdiagrams, perform the transformation using the list of most recent subdiagrams associated with (some qualification of) each name. Do nothing (the identity transformation) if any of the names do not exist.

withNameAll :: (IsName nm, Metric v, Semigroup m, OrderedField n) => nm -> ([Subdiagram b v n m] -> QDiagram b v n m -> QDiagram b v n m) -> QDiagram b v n m -> QDiagram b v n m #

Given a name and a diagram transformation indexed by a list of subdiagrams, perform the transformation using the collection of all such subdiagrams associated with (some qualification of) the given name.

withName :: (IsName nm, Metric v, Semigroup m, OrderedField n) => nm -> (Subdiagram b v n m -> QDiagram b v n m -> QDiagram b v n m) -> QDiagram b v n m -> QDiagram b v n m #

Given a name and a diagram transformation indexed by a subdiagram, perform the transformation using the most recent subdiagram associated with (some qualification of) the name, or perform the identity transformation if the name does not exist.

lookupName :: (IsName nm, Metric v, Semigroup m, OrderedField n) => nm -> QDiagram b v n m -> Maybe (Subdiagram b v n m) #

Lookup the most recent diagram associated with (some qualification of) the given name.

nameSub :: (IsName nm, Metric v, OrderedField n, Semigroup m) => (QDiagram b v n m -> Subdiagram b v n m) -> nm -> QDiagram b v n m -> QDiagram b v n m #

Attach an atomic name to a certain subdiagram, computed from the given diagram /with the mapping from name to subdiagram included/. The upshot of this knot-tying is that if d' = d # named x, then lookupName x d' == Just d' (instead of Just d).

names :: (Metric v, Semigroup m, OrderedField n) => QDiagram b v n m -> [(Name, [Point v n])] #

Get a list of names of subdiagrams and their locations.

subMap :: (Metric v, Semigroup m, OrderedField n) => Lens' (QDiagram b v n m) (SubMap b v n m) #

Lens onto the SubMap of a QDiagram (i.e. an association from names to subdiagrams).

setTrace :: (OrderedField n, Metric v, Semigroup m) => Trace v n -> QDiagram b v n m -> QDiagram b v n m #

Replace the trace of a diagram.

setEnvelope :: (OrderedField n, Metric v, Monoid' m) => Envelope v n -> QDiagram b v n m -> QDiagram b v n m #

Replace the envelope of a diagram.

envelope :: (OrderedField n, Metric v, Monoid' m) => Lens' (QDiagram b v n m) (Envelope v n) #

Lens onto the Envelope of a QDiagram.

pointDiagram :: (Metric v, Fractional n) => Point v n -> QDiagram b v n m #

groupOpacity :: (Metric v, OrderedField n, Semigroup m) => Double -> QDiagram b v n m -> QDiagram b v n m #

Change the transparency of a Diagram as a group.

opacityGroup :: (Metric v, OrderedField n, Semigroup m) => Double -> QDiagram b v n m -> QDiagram b v n m #

Change the transparency of a Diagram as a group.

href :: (Metric v, OrderedField n, Semigroup m) => String -> QDiagram b v n m -> QDiagram b v n m #

Make a diagram into a hyperlink. Note that only some backends will honor hyperlink annotations.

type TypeableFloat n = (Typeable n, RealFloat n) #

Constraint for numeric types that are RealFloat and Typeable, which often occur together. This is used to shorten shorten type constraint contexts.

data QDiagram b (v :: Type -> Type) n m #

The fundamental diagram type. The type variables are as follows:

b represents the backend, such as SVG or Cairo. Note that each backend also exports a type synonym B for itself, so the type variable b may also typically be instantiated by B, meaning "use whatever backend is in scope".
v represents the vector space of the diagram. Typical instantiations include V2 (for a two-dimensional diagram) or V3 (for a three-dimensional diagram).
n represents the numerical field the diagram uses. Typically this will be a concrete numeric type like Double.
m is the monoidal type of "query annotations": each point in the diagram has a value of type m associated to it, and these values are combined according to the Monoid instance for m. Most often, m is simply instantiated to Any, associating a simple Bool value to each point indicating whether the point is inside the diagram; Diagram is a synonym for QDiagram with m thus instantiated to Any.

Diagrams can be combined via their Monoid instance, transformed via their Transformable instance, and assigned attributes via their HasStyle instance.

Note that the Q in QDiagram stands for "Queriable", as distinguished from Diagram, where m is fixed to Any. This is not really a very good name, but it's probably not worth changing it at this point.

Diagrams compose by aligning their respective local origins. The new diagram has all the primitives and all the names from the two diagrams combined, and query functions are combined pointwise. The first diagram goes on top of the second. "On top of" probably only makes sense in vector spaces of dimension lower than 3, but in theory it could make sense for, say, 3-dimensional diagrams when viewed by 4-dimensional beings.

class Backend b (v :: Type -> Type) n where #

Abstract diagrams are rendered to particular formats by backends. Each backend/vector space combination must be an instance of the Backend class.

A minimal complete definition consists of Render, Result, Options, and renderRTree. However, most backends will want to implement adjustDia as well; the default definition does nothing. Some useful standard definitions are provided in the Diagrams.TwoD.Adjust module from the diagrams-lib package.

Minimal complete definition

renderRTree

Associated Types

data Render b (v :: Type -> Type) n :: Type #

An intermediate representation used for rendering primitives. (Typically, this will be some sort of monad, but it need not be.) The Renderable class guarantees that a backend will be able to convert primitives into this type; how these rendered primitives are combined into an ultimate Result is completely up to the backend.

type Result b (v :: Type -> Type) n :: Type #

The result of running/interpreting a rendering operation.

data Options b (v :: Type -> Type) n :: Type #

Backend-specific rendering options.

Methods

adjustDia :: (Additive v, Monoid' m, Num n) => b -> Options b v n -> QDiagram b v n m -> (Options b v n, Transformation v n, QDiagram b v n m) #

adjustDia allows the backend to make adjustments to the final diagram (e.g. to adjust the size based on the options) before rendering it. It returns a modified options record, the transformation applied to the diagram (which can be used to convert attributes whose value is Measure, or transform e.g. screen coordinates back into local diagram coordinates), and the adjusted diagram itself.

See the diagrams-lib package (particularly the Diagrams.TwoD.Adjust module) for some useful implementations.

renderRTree :: b -> Options b v n -> RTree b v n Annotation -> Result b v n #

Given some options, take a representation of a diagram as a tree and render it. The RTree has already been simplified and has all measurements converted to Output units.

type D (v :: Type -> Type) n = QDiagram NullBackend v n Any #

The D type is provided for convenience in situations where you must give a diagram a concrete, monomorphic type, but don't care which one. Such situations arise when you pass a diagram to a function which is polymorphic in its input but monomorphic in its output, such as width, height, phantom, or names. Such functions compute some property of the diagram, or use it to accomplish some other purpose, but do not result in the diagram being rendered. If the diagram does not have a monomorphic type, GHC complains that it cannot determine the diagram's type.

For example, here is the error we get if we try to compute the width of an image (this example requires diagrams-lib):

  ghci> width (image (uncheckedImageRef "foo.png" 200 200))
  <interactive>:11:8:
      No instance for (Renderable (DImage n0 External) b0)
        arising from a use of image
      The type variables n0, b0 are ambiguous
      Possible fix: add a type signature that fixes these type variable(s)
      Note: there is a potential instance available:
        instance Fractional n => Renderable (DImage n a) NullBackend
          -- Defined in Image
      Possible fix:
        add an instance declaration for
        (Renderable (DImage n0 External) b0)
      In the first argument of width, namely
        `(image (uncheckedImageRef "foo.png" 200 200))'
      In the expression:
        width (image (uncheckedImageRef "foo.png" 200 200))
      In an equation for it:
          it = width (image (uncheckedImageRef "foo.png" 200 200))

GHC complains that there is no instance for Renderable (DImage n0 External) b0; what is really going on is that it does not have enough information to decide what backend to use (hence the uninstantiated n0 and b0). This is annoying because we know that the choice of backend cannot possibly affect the width of the image (it's 200! it's right there in the code!); but there is no way for GHC to know that.

The solution is to annotate the call to image with the type D V2 Double, like so:

  ghci> width (image (uncheckedImageRef "foo.png" 200 200) :: D V2 Double)
  200.00000000000006

(It turns out the width wasn't 200 after all...)

As another example, here is the error we get if we try to compute the width of a radius-1 circle:

  ghci> width (circle 1)
  <interactive>:12:1:
      Couldn't match expected type V2 with actual type `V a0'
      The type variable a0 is ambiguous
      Possible fix: add a type signature that fixes these type variable(s)
      In the expression: width (circle 1)
      In an equation for it: it = width (circle 1)

There's even more ambiguity here. Whereas image always returns a Diagram, the circle function can produce any TrailLike type, and the width function can consume any Enveloped type, so GHC has no idea what type to pick to go in the middle. However, the solution is the same:

  ghci> width (circle 1 :: D V2 Double)
  1.9999999999999998

data NullBackend #

A null backend which does no actual rendering. It is provided mainly for convenience in situations where you must give a diagram a concrete, monomorphic type, but don't actually care which one. See D for more explanation and examples.

It is courteous, when defining a new primitive P, to make an instance

instance Renderable P NullBackend where
  render _ _ = mempty

This ensures that the trick with D annotations can be used for diagrams containing your primitive.

juxtaposeDefault :: (Enveloped a, HasOrigin a) => Vn a -> a -> a -> a #

Default implementation of juxtapose for things which are instances of Enveloped and HasOrigin. If either envelope is empty, the second object is returned unchanged.

class Juxtaposable a where #

Class of things which can be placed "next to" other things, for some appropriate notion of "next to".

Methods

juxtapose :: Vn a -> a -> a -> a #

juxtapose v a1 a2 positions a2 next to a1 in the direction of v. In particular, place a2 so that v points from the local origin of a1 towards the old local origin of a2; a1's local origin becomes a2's new local origin. The result is just a translated version of a2. (In particular, this operation does not combine a1 and a2 in any way.)

size :: (V a ~ v, N a ~ n, Enveloped a, HasBasis v) => a -> v n #

The smallest positive axis-parallel vector that bounds the envelope of an object.

radius :: (V a ~ v, N a ~ n, Enveloped a) => v n -> a -> n #

Compute the "radius" (1/2 the diameter) of an enveloped object along a particular vector.

Compute the point on a separating hyperplane in the given direction, or Nothing for the empty envelope.

envelopeV :: Enveloped a => Vn a -> a -> Vn a #

Compute the vector from the local origin to a separating hyperplane in the given direction. Returns the zero vector for the empty envelope.

envelopeVMay :: Enveloped a => Vn a -> a -> Maybe (Vn a) #

Compute the vector from the local origin to a separating hyperplane in the given direction, or Nothing for the empty envelope.

mkEnvelope :: (v n -> n) -> Envelope v n #

Create an envelope from a v n -> n function.

onEnvelope :: ((v n -> n) -> v n -> n) -> Envelope v n -> Envelope v n #

A convenient way to transform an envelope, by specifying a transformation on the underlying v n -> n function. The empty envelope is unaffected.

appEnvelope :: Envelope v n -> Maybe (v n -> n) #

"Apply" an envelope by turning it into a function. Nothing is returned iff the envelope is empty.

newtype Envelope (v :: Type -> Type) n #

Every diagram comes equipped with an envelope. What is an envelope?

Consider first the idea of a bounding box. A bounding box expresses the distance to a bounding plane in every direction parallel to an axis. That is, a bounding box can be thought of as the intersection of a collection of half-planes, two perpendicular to each axis.

More generally, the intersection of half-planes in every direction would give a tight "bounding region", or convex hull. However, representing such a thing intensionally would be impossible; hence bounding boxes are often used as an approximation.

An envelope is an extensional representation of such a "bounding region". Instead of storing some sort of direct representation, we store a function which takes a direction as input and gives a distance to a bounding half-plane as output. The important point is that envelopes can be composed, and transformed by any affine transformation.

Formally, given a vector v, the envelope computes a scalar s such that

for every point u inside the diagram, if the projection of (u - origin) onto v is s' *^ v, then s' <= s.
s is the smallest such scalar.

There is also a special "empty envelope".

The idea for envelopes came from Sebastian Setzer; see http://byorgey.wordpress.com/2009/10/28/collecting-attributes/#comment-2030.

Compute the envelope of an object. For types with an intrinsic notion of "local origin", the envelope will be based there. Other types (e.g. Trail) may have some other default reference point at which the envelope will be based; their instances should document what it is.

newtype Query (v :: Type -> Type) n m #

A query is a function that maps points in a vector space to values in some monoid. Queries naturally form a monoid, with two queries being combined pointwise.

The idea for annotating diagrams with monoidal queries came from the graphics-drawingcombinators package, http://hackage.haskell.org/package/graphics-drawingcombinators.

maxRayTraceP :: (n ~ N a, Traced a, Num n) => Point (V a) n -> V a n -> a -> Maybe (Point (V a) n) #

Like rayTraceP, but computes the "largest" boundary point instead of the smallest. Considers only positive boundary points.

maxRayTraceV :: (n ~ N a, Traced a, Num n) => Point (V a) n -> V a n -> a -> Maybe (V a n) #

rayTraceP :: (n ~ N a, Traced a, Num n) => Point (V a) n -> V a n -> a -> Maybe (Point (V a) n) #

Compute the boundary point on an object which is closest to the given base point in the given direction, or Nothing if there is no such boundary point. Note that unlike traceP, only positive boundary points are considered, i.e. boundary points corresponding to a positive scalar multiple of the direction vector. This is intuitively the "usual" behavior of a raytracer, which only considers intersection points "in front of" the camera.

rayTraceV :: (n ~ N a, Traced a, Num n) => Point (V a) n -> V a n -> a -> Maybe (V a n) #

Compute the vector from the given point to the closest boundary point of the given object in the given direction, or Nothing if there is no such boundary point (as in the third example below). Note that unlike traceV, only positive boundary points are considered, i.e. boundary points corresponding to a positive scalar multiple of the direction vector. This is intuitively the "usual" behavior of a raytracer, which only considers intersections "in front of" the camera. Compare the second example diagram below with the second example shown for traceV.

maxTraceP :: (n ~ N a, Num n, Traced a) => Point (V a) n -> V a n -> a -> Maybe (Point (V a) n) #

maxTraceV :: (n ~ N a, Num n, Traced a) => Point (V a) n -> V a n -> a -> Maybe (V a n) #

Like traceV, but computes a vector to the "largest" boundary point instead of the smallest. (Note, however, the "largest" boundary point may still be in the opposite direction from the given vector, if all the boundary points are, as in the third example shown below.)

traceP :: (n ~ N a, Traced a, Num n) => Point (V a) n -> V a n -> a -> Maybe (Point (V a) n) #

Compute the "smallest" boundary point along the line determined by the given point p and vector v. The "smallest" boundary point is defined as the one given by p .+^ (s *^ v) for the smallest (most negative) value of s. Return Nothing if there is no such boundary point. See also traceV.

See also rayTraceP which uses the smallest positive intersection, which is often more intuitive behavior.

traceV :: (n ~ N a, Num n, Traced a) => Point (V a) n -> V a n -> a -> Maybe (V a n) #

Compute the vector from the given point p to the "smallest" boundary intersection along the given vector v. The "smallest" boundary intersection is defined as the one given by p .+^ (s *^ v) for the smallest (most negative) value of s. Return Nothing if there is no intersection. See also traceP.

newtype Trace (v :: Type -> Type) n #

Every diagram comes equipped with a trace. Intuitively, the trace for a diagram is like a raytracer: given a line (represented as a base point and a direction vector), the trace computes a sorted list of signed distances from the base point to all intersections of the line with the boundary of the diagram.

Note that the outputs are not absolute distances, but multipliers relative to the input vector. That is, if the base point is p and direction vector is v, and one of the output scalars is s, then there is an intersection at the point p .+^ (s *^ v).

class (Typeable a, Ord a, Show a) => IsName a where #

Class for those types which can be used as names. They must support Typeable (to facilitate extracting them from existential wrappers), Ord (for comparison and efficient storage) and Show.

To make an instance of IsName, you need not define any methods, just declare it.

WARNING: it is not recommended to use GeneralizedNewtypeDeriving in conjunction with IsName, since in that case the underlying type and the newtype will be considered equivalent when comparing names. For example:

    newtype WordN = WordN Int deriving (Show, Ord, Eq, Typeable, IsName)

is unlikely to work as intended, since (1 :: Int) and (WordN 1) will be considered equal as names. Instead, use

    newtype WordN = WordN Int deriving (Show, Ord, Eq, Typeable, IsName)
    instance IsName WordN

getAttr :: AttributeClass a => Style v n -> Maybe a #

Extract an attribute from a style of a particular type. If the style contains an attribute of the requested type, it will be returned wrapped in Just; otherwise, Nothing is returned.

Trying to extract a measured attibute will fail. It either has to be unmeasured with unmeasureAttrs or use the atMAttr lens.

By the transpose of a linear map we mean simply the linear map corresponding to the transpose of the map's matrix representation. For example, any scale is its own transpose, since scales are represented by matrices with zeros everywhere except the diagonal. The transpose of a rotation is the same as its inverse.

The reason we need to keep track of transposes is because it turns out that when transforming a shape according to some linear map L, the shape's normal vectors transform according to L's inverse transpose. (For a more detailed explanation and proof, see https://wiki.haskell.org/Diagrams/Dev/Transformations.) This is exactly what we need when transforming bounding functions, which are defined in terms of perpendicular (i.e. normal) hyperplanes.

For more general, non-invertible transformations, see Diagrams.Deform (in diagrams-lib).

place :: (InSpace v n t, HasOrigin t) => t -> Point v n -> t #

A flipped variant of moveTo, provided for convenience. Useful when writing a function which takes a point as an argument, such as when using withName and friends.

moveTo :: (InSpace v n t, HasOrigin t) => Point v n -> t -> t #

Translate the object by the translation that sends the origin to the given point. Note that this is dual to moveOriginTo, i.e. we should have

  moveTo (origin .^+ v) === moveOriginTo (origin .^- v)

For types which are also Transformable, this is essentially the same as translate, i.e.

  moveTo (origin .^+ v) === translate v

moveOriginBy :: (V t ~ v, N t ~ n, HasOrigin t) => v n -> t -> t #

Move the local origin by a relative vector.

class HasOrigin t where #

Class of types which have an intrinsic notion of a "local origin", i.e. things which are not invariant under translation, and which allow the origin to be moved.

One might wonder why not just use Transformable instead of having a separate class for HasOrigin; indeed, for types which are instances of both we should have the identity

  moveOriginTo (origin .^+ v) === translate (negated v)

The reason is that some things (e.g. vectors, Trails) are transformable but are translationally invariant, i.e. have no origin.

Methods

moveOriginTo :: Point (V t) (N t) -> t -> t #

Move the local origin to another point.

Note that this function is in some sense dual to translate (for types which are also Transformable); moving the origin itself while leaving the object "fixed" is dual to fixing the origin and translating the diagram.

type Vn a = V a (N a) #

Conveient type alias to retrieve the vector type associated with an object's vector space. This is usually used as Vn a ~ v n where v is the vector space and n is the numerical field.

type InSpace (v :: Type -> Type) n a = (V a ~ v, N a ~ n, Additive v, Num n) #

InSpace v n a means the type a belongs to the vector space v n, where v is Additive and n is a Num.

type SameSpace a b = (V a ~ V b, N a ~ N b) #

SameSpace a b means the types a and b belong to the same vector space v n.

type Monoid' = Monoid #

For base < 4.11, the Monoid' constraint is a synonym for things which are instances of both Semigroup and Monoid. For base version 4.11 and onwards, Monoid has Semigroup as a superclass already, so for backwards compatibility Monoid' is provided as a synonym for Monoid.

basis :: (Additive t, Traversable t, Num a) => [t a] #

Produce a default basis for a vector space. If the dimensionality of the vector space is not statically known, see basisFor.

newtype Point (f :: Type -> Type) a #

A handy wrapper to help distinguish points from vectors at the type level

(Additive v, Ord n) => Traced (Point v n)	The trace of a single point is the empty trace, i.e. the one which returns no intersection points for every query. Arguably it should return a single finite distance for vectors aimed directly at the given point, but due to floating-point inaccuracy this is problematic. Note that the envelope for a single point is not the empty envelope (see Diagrams.Core.Envelope).

animRect' :: (InSpace V2 n t, Monoid' m, TrailLike t, Enveloped t, Transformable t, Monoid t) => Rational -> QAnimation b V2 n m -> t #

Like animRect, but with an adjustible sample rate. The first parameter is the number of samples per time unit to use. Lower rates will be faster but less accurate; higher rates are more accurate but slower.

animRect :: (InSpace V2 n t, Monoid' m, TrailLike t, Enveloped t, Transformable t, Monoid t) => QAnimation b V2 n m -> t #

animRect works similarly to animEnvelope for 2D diagrams, but instead of adjusting the envelope, simply returns the smallest bounding rectangle which encloses the entire animation. Useful for e.g. creating a background to go behind an animation.

Uses 30 samples per time unit by default; to adjust this number see animRect'.

animEnvelope' :: (OrderedField n, Metric v, Monoid' m) => Rational -> QAnimation b v n m -> QAnimation b v n m #

Like animEnvelope, but with an adjustible sample rate. The first parameter is the number of samples per time unit to use. Lower rates will be faster but less accurate; higher rates are more accurate but slower.

animEnvelope :: (OrderedField n, Metric v, Monoid' m) => QAnimation b v n m -> QAnimation b v n m #

Automatically assign fixed a envelope to the entirety of an animation by sampling the envelope at a number of points in time and taking the union of all the sampled envelopes to form the "hull". This hull is then used uniformly throughout the animation.

This is useful when you have an animation that grows and shrinks in size or shape over time, but you want it to take up a fixed amount of space, e.g. so that the final rendered movie does not zoom in and out, or so that it occupies a fixed location with respect to another animation, when combining animations with something like |||.

By default, 30 samples per time unit are used; to adjust this number see animEnvelope'.

See also animRect for help constructing a background to go behind an animation.

type QAnimation b (v :: Type -> Type) n m = Active (QDiagram b v n m) #

A value of type QAnimation b v m is an animation (a time-varying diagram with start and end times) that can be rendered by backend b, with vector space v and monoidal annotations of type m.

type Animation b (v :: Type -> Type) n = QAnimation b v n Any #

A value of type Animation b v is an animation (a time-varying diagram with start and end times) in vector space v that can be rendered by backspace b.

Note that Animation is actually a synonym for QAnimation where the type of the monoidal annotations has been fixed to Any (the default).

mkHeight :: Num n => n -> SizeSpec V2 n #

Make a SizeSpec with only height defined.

mkWidth :: Num n => n -> SizeSpec V2 n #

Make a SizeSpec with only width defined.

dims2D :: n -> n -> SizeSpec V2 n #

Make a SizeSpec from a width and height.

mkSizeSpec2D :: Num n => Maybe n -> Maybe n -> SizeSpec V2 n #

Make a SizeSpec from possibly-specified width and height.

extentY :: (InSpace v n a, R2 v, Enveloped a) => a -> Maybe (n, n) #

Compute the absolute y-coordinate range of an enveloped object in the form (lo,hi). Return Nothing for objects with an empty envelope.

extentX :: (InSpace v n a, R1 v, Enveloped a) => a -> Maybe (n, n) #

Compute the absolute x-coordinate range of an enveloped object in the form (lo,hi). Return Nothing for objects with an empty envelope.

Note this is just extent unitX.

height :: (InSpace V2 n a, Enveloped a) => a -> n #

Compute the height of an enveloped object.

width :: (InSpace V2 n a, Enveloped a) => a -> n #

Compute the width of an enveloped object.

Note this is just diameter unitX.

sizeAdjustment :: (Additive v, Foldable v, OrderedField n) => SizeSpec v n -> BoundingBox v n -> (v n, Transformation v n) #

Get the adjustment to fit a BoundingBox in the given SizeSpec. The vector is the new size and the transformation to position the lower corner at the origin and scale to the size spec.

sizedAs :: (InSpace v n a, SameSpace a b, HasLinearMap v, Transformable a, Enveloped a, Enveloped b) => b -> a -> a #

Uniformly scale an enveloped object so that it "has the same size as" (fits within the width and height of) some other object.

sized :: (InSpace v n a, HasLinearMap v, Transformable a, Enveloped a) => SizeSpec v n -> a -> a #

Uniformly scale any enveloped object so that it fits within the given size. For non-uniform scaling see boxFit.

requiredScaling :: (Additive v, Foldable v, Fractional n, Ord n) => SizeSpec v n -> v n -> Transformation v n #

Return the Transformation calcuated from requiredScale.

requiredScale :: (Additive v, Foldable v, Fractional n, Ord n) => SizeSpec v n -> v n -> n #

requiredScale spec sz returns the largest scaling factor to make something of size sz fit the requested size spec without changing the aspect ratio. sz should be non-zero (otherwise a scale of 1 is returned). For non-uniform scaling see boxFit.

specToSize :: (Foldable v, Functor v, Num n, Ord n) => n -> SizeSpec v n -> v n #

specToSize n spec extracts a size from a SizeSpec sz. Any values not specified in the spec are replaced by the smallest of the values that are specified. If there are no specified values (i.e. absolute) then n is used.

absolute :: (Additive v, Num n) => SizeSpec v n #

A size spec with no hints to the size.

dims :: v n -> SizeSpec v n #

Make a SizeSpec from a vector. Any negative values will be ignored.

mkSizeSpec :: (Functor v, Num n) => v (Maybe n) -> SizeSpec v n #

Make a SizeSpec from a vector of maybe values. Any negative values will be ignored. For 2D SizeSpecs see mkWidth and mkHeight from Diagrams.TwoD.Size.

getSpec :: (Functor v, Num n, Ord n) => SizeSpec v n -> v (Maybe n) #

Retrieve a size spec as a vector of maybe values. Only positive sizes are returned.

data SizeSpec (v :: Type -> Type) n #

A SizeSpec is a way of specifying a size without needed lengths for all the dimensions.

bg :: (TypeableFloat n, Renderable (Path V2 n) b) => Colour Double -> QDiagram b V2 n Any -> QDiagram b V2 n Any #

"Set the background color" of a diagram. That is, place a diagram atop a bounding rectangle of the given color.

rectEnvelope :: (OrderedField n, Monoid' m) => Point V2 n -> V2 n -> QDiagram b V2 n m -> QDiagram b V2 n m #

rectEnvelope p v sets the envelope of a diagram to a rectangle whose lower-left corner is at p and whose upper-right corner is at p .+^ v. Useful for selecting the rectangular portion of a diagram which should actually be "viewed" in the final render, if you don't want to see the entire diagram.

extrudeTop :: (OrderedField n, Monoid' m) => n -> QDiagram b V2 n m -> QDiagram b V2 n m #

extrudeTop s "extrudes" a diagram in the positive y-direction, offsetting its envelope by the provided distance. When s < 0 , the envelope is inset instead.

See the documentation for extrudeEnvelope for more information.

extrudeBottom :: (OrderedField n, Monoid' m) => n -> QDiagram b V2 n m -> QDiagram b V2 n m #

extrudeBottom s "extrudes" a diagram in the negative y-direction, offsetting its envelope by the provided distance. When s < 0 , the envelope is inset instead.

padY s "pads" a diagram in the y-direction, expanding its envelope vertically by a factor of s (factors between 0 and 1 can be used to shrink the envelope). Note that the envelope will expand with respect to the local origin, so if the origin is not centered vertically the padding may appear "uneven". If this is not desired, the origin can be centered (using centerY) before applying padY.

padX :: (Metric v, R2 v, OrderedField n, Monoid' m) => n -> QDiagram b v n m -> QDiagram b v n m #

padX s "pads" a diagram in the x-direction, expanding its envelope horizontally by a factor of s (factors between 0 and 1 can be used to shrink the envelope). Note that the envelope will expand with respect to the local origin, so if the origin is not centered horizontally the padding may appear "uneven". If this is not desired, the origin can be centered (using centerX) before applying padX.

roundedRect' :: (InSpace V2 n t, TrailLike t, RealFloat n) => n -> n -> RoundedRectOpts n -> t #

roundedRect' works like roundedRect but allows you to set the radius of each corner indivually, using RoundedRectOpts. The default corner radius is 0. Each radius can also be negative, which results in the curves being reversed to be inward instead of outward.

roundedRect :: (InSpace V2 n t, TrailLike t, RealFloat n) => n -> n -> n -> t #

roundedRect w h r generates a closed trail, or closed path centered at the origin, of an axis-aligned rectangle with width w, height h, and circular rounded corners of radius r. If r is negative the corner will be cut out in a reverse arc. If the size of r is larger than half the smaller dimension of w and h, then it will be reduced to fit in that range, to prevent the corners from overlapping. The trail or path begins with the right edge and proceeds counterclockwise. If you need to specify a different radius for each corner individually, use roundedRect' instead.

Create a regular polygon. The first argument is the number of sides, and the second is the length of the sides. (Compare to the polygon function with a PolyRegular option, which produces polygons of a given radius).

The polygon will be oriented with one edge parallel to the x-axis.

rect :: (InSpace V2 n t, TrailLike t) => n -> n -> t #

rect w h is an axis-aligned rectangle of width w and height h, centered at the origin.

square :: (InSpace V2 n t, TrailLike t) => n -> t #

A square with its center at the origin and sides of the given length, oriented parallel to the axes.

unitSquare :: (InSpace V2 n t, TrailLike t) => t #

A square with its center at the origin and sides of length 1, oriented parallel to the axes.

vrule :: (InSpace V2 n t, TrailLike t) => n -> t #

Create a centered vertical (T-B) line of the given length.

vruleEx = hcat' (with & sep .~ 0.2) (map vrule [1, 1.2 .. 2])
        # centerXY # pad 1.1

hrule :: (InSpace V2 n t, TrailLike t) => n -> t #

Create a centered horizontal (L-R) line of the given length.

hruleEx = vcat' (with & sep .~ 0.2) (map hrule [1..5])
        # centerXY # pad 1.1

star :: OrderedField n => StarOpts -> [Point V2 n] -> Path V2 n #

Create a generalized star polygon. The StarOpts are used to determine in which order the given vertices should be connected. The intention is that the second argument of type [Point v] could be generated by a call to polygon, regPoly, or the like, since a list of vertices is TrailLike. But of course the list can be generated any way you like. A Path v is returned (instead of any TrailLike) because the resulting path may have more than one component, for example if the vertices are to be connected in several disjoint cycles.

polygon :: (InSpace V2 n t, TrailLike t) => PolygonOpts n -> t #

Generate the polygon described by the given options.

polyTrail :: OrderedField n => PolygonOpts n -> Located (Trail V2 n) #

Generate a polygon. See PolygonOpts for more information.

polyType :: Lens' (PolygonOpts n) (PolyType n) #

Specification for the polygon's vertices.

polyOrient :: Lens' (PolygonOpts n) (PolyOrientation n) #

Should a rotation be applied to the polygon in order to orient it in a particular way?

polyCenter :: Lens' (PolygonOpts n) (Point V2 n) #

Should a translation be applied to the polygon in order to place the center at a particular location?

data StarOpts #

Options for creating "star" polygons, where the edges connect possibly non-adjacent vertices.

Constructors

StarFun (Int -> Int)	Specify the order in which the vertices should be connected by a function that maps each vertex index to the index of the vertex that should come next. Indexing of vertices begins at 0.
StarSkip Int	Specify a star polygon by a "skip". A skip of 1 indicates a normal polygon, where edges go between successive vertices. A skip of 2 means that edges will connect every second vertex, skipping one in between. Generally, a skip of n means that edges will connect every nth vertex.

data PolyType n #

Method used to determine the vertices of a polygon.

Constructors

PolyPolar [Angle n] [n]

A "polar" polygon.

The first argument is a list of central angles from each vertex to the next.
The second argument is a list of radii from the origin to each successive vertex.

To construct an n-gon, use a list of n-1 angles and n radii. Extra angles or radii are ignored.

Cyclic polygons (with all vertices lying on a circle) can be constructed using a second argument of (repeat r).

PolySides [Angle n] [n]

A polygon determined by the distance between successive vertices and the external angles formed by each three successive vertices. In other words, a polygon specified by "turtle graphics": go straight ahead x1 units; turn by external angle a1; go straight ahead x2 units; turn by external angle a2; etc. The polygon will be centered at the centroid of its vertices.

The first argument is a list of vertex angles, giving the external angle at each vertex from the previous vertex to the next. The first angle in the list is the external angle at the second vertex; the first edge always starts out heading in the positive y direction from the first vertex.
The second argument is a list of distances between successive vertices.

To construct an n-gon, use a list of n-2 angles and n-1 edge lengths. Extra angles or lengths are ignored.

PolyRegular Int n

A regular polygon with the given number of sides (first argument) and the given radius (second argument).

data PolyOrientation n #

Determine how a polygon should be oriented.

Constructors

NoOrient	No special orientation; the first vertex will be at (1,0).
OrientH	Orient horizontally, so the bottommost edge is parallel to the x-axis. This is the default.
OrientV	Orient vertically, so the leftmost edge is parallel to the y-axis.
OrientTo (V2 n)	Orient so some edge is facing in the direction of, that is, perpendicular to, the given vector.

reversePath :: (Metric v, OrderedField n) => Path v n -> Path v n #

Reverse all the component trails of a path.

scalePath :: (HasLinearMap v, Metric v, OrderedField n) => n -> Path v n -> Path v n #

Scale a path using its centroid (see pathCentroid) as the base point for the scale.

partitionPath :: (Located (Trail v n) -> Bool) -> Path v n -> (Path v n, Path v n) #

Partition a path into two paths based on a predicate on trails: the first containing all the trails for which the predicate returns True, and the second containing the remaining trails.

explodePath :: (V t ~ v, N t ~ n, TrailLike t) => Path v n -> [[t]] #

"Explode" a path by exploding every component trail (see explodeTrail).

fixPath :: (Metric v, OrderedField n) => Path v n -> [[FixedSegment v n]] #

Convert a path into a list of lists of FixedSegments.

pathLocSegments :: (Metric v, OrderedField n) => Path v n -> [[Located (Segment Closed v n)]] #

Convert a path into a list of lists of located segments.

pathCentroid :: (Metric v, OrderedField n) => Path v n -> Point v n #

Compute the centroid of a path (i.e. the average location of its vertices; see pathVertices).

pathOffsets :: (Metric v, OrderedField n) => Path v n -> [v n] #

Compute the total offset of each trail comprising a path (see trailOffset).

pathVertices :: (Metric v, OrderedField n) => Path v n -> [[Point v n]] #

Like pathVertices', with a default tolerance.

pathVertices' :: (Metric v, OrderedField n) => n -> Path v n -> [[Point v n]] #

Extract the vertices of a path, resulting in a separate list of vertices for each component trail. Here a vertex is defined as a non-differentiable point on the trail, i.e. a sharp corner. (Vertices are thus a subset of the places where segments join; if you want all joins between segments, see pathPoints.) The tolerance determines how close the tangents of two segments must be at their endpoints to consider the transition point to be differentiable. See trailVertices for more information.

pathFromLocTrail :: (Metric v, OrderedField n) => Located (Trail v n) -> Path v n #

Convert a located trail to a singleton path. This is equivalent to trailLike, but provided with a more specific name and type for convenience.

pathFromTrailAt :: (Metric v, OrderedField n) => Trail v n -> Point v n -> Path v n #

Convert a trail to a path with a particular starting point.

pathFromTrail :: (Metric v, OrderedField n) => Trail v n -> Path v n #

Convert a trail to a path beginning at the origin.

pathTrails :: Path v n -> [Located (Trail v n)] #

Extract the located trails making up a Path.

newtype Path (v :: Type -> Type) n #

A path is a (possibly empty) list of Located Trails. Hence, unlike trails, paths are not translationally invariant, and they form a monoid under superposition (placing one path on top of another) rather than concatenation.

boundaryFrom :: (OrderedField n, Metric v, Semigroup m) => Subdiagram b v n m -> v n -> Point v n #

composeAligned #

Arguments

:: (Monoid' m, Floating n, Ord n, Metric v)
=> (QDiagram b v n m -> QDiagram b v n m)	Alignment function
-> ([QDiagram b v n m] -> QDiagram b v n m)	Composition function
-> [QDiagram b v n m]
-> QDiagram b v n m

Compose a list of diagrams using the given composition function, first aligning them all according to the given alignment, but retain the local origin of the first diagram, as it would be if the composition function were applied directly. That is, composeAligned algn comp is equivalent to translate v . comp . map algn for some appropriate translation vector v.

Unfortunately, this only works for diagrams (and not, say, paths) because there is no most general type for alignment functions, and no generic way to find out what an alignment function does to the origin of things. (However, it should be possible to make a version of this function that works specifically on paths, if such a thing were deemed useful.)

alignedEx1 = (hsep 2 # composeAligned alignT) (map circle [1,3,5,2])
           # showOrigin
           # frame 0.5

alignedEx2 = (mconcat # composeAligned alignTL) [circle 1, square 1, triangle 1, pentagon 1]
           # showOrigin
           # frame 0.1

cat' :: (InSpace v n a, Metric v, Floating n, Juxtaposable a, Monoid' a, HasOrigin a) => v n -> CatOpts n -> [a] -> a #

Like cat, but taking an extra CatOpts arguments allowing the user to specify

The spacing method: catenation (uniform spacing between envelopes) or distribution (uniform spacing between local origins). The default is catenation.
The amount of separation between successive diagram envelopes/origins (depending on the spacing method). The default is 0.

CatOpts is an instance of Default, so with may be used for the second argument, as in cat' (1,2) (with & sep .~ 2).

Note that cat' v (with & catMethod .~ Distrib) === mconcat (distributing with a separation of 0 is the same as superimposing).

cat :: (InSpace v n a, Metric v, Floating n, Juxtaposable a, Monoid' a, HasOrigin a) => v n -> [a] -> a #

cat v positions a list of objects so that their local origins lie along a line in the direction of v. Successive objects will have their envelopes just touching. The local origin of the result will be the same as the local origin of the first object.

See also cat', which takes an extra options record allowing certain aspects of the operation to be tweaked.

sep :: Lens' (CatOpts n) n #

How much separation should be used between successive diagrams (default: 0)? When catMethod = Cat, this is the distance between envelopes; when catMethod = Distrib, this is the distance between origins.

catMethod :: Lens' (CatOpts n) CatMethod #

Which CatMethod should be used: normal catenation (default), or distribution?

atPoints :: (InSpace v n a, HasOrigin a, Monoid' a) => [Point v n] -> [a] -> a #

Curried version of position, takes a list of points and a list of objects.

position :: (InSpace v n a, HasOrigin a, Monoid' a) => [(Point v n, a)] -> a #

Position things absolutely: combine a list of objects (e.g. diagrams or paths) by assigning them absolute positions in the vector space of the combined object.

positionEx = position (zip (map mkPoint [-3, -2.8 .. 3]) (repeat spot))
  where spot      = circle 0.2 # fc black
        mkPoint :: Double -> P2 Double
        mkPoint x = p2 (x,x*x)

appends :: (Juxtaposable a, Monoid' a) => a -> [(Vn a, a)] -> a #

appends x ys appends each of the objects in ys to the object x in the corresponding direction. Note that each object in ys is positioned beside x without reference to the other objects in ys, so this is not the same as iterating beside.

appendsEx = appends c (zip (iterateN 6 (rotateBy (1/6)) unitX) (repeat c))
            # centerXY # pad 1.1
  where c = circle 1

atDirection :: (InSpace v n a, Metric v, Floating n, Juxtaposable a, Semigroup a) => Direction v n -> a -> a -> a #

Place two diagrams (or other juxtaposable objects) adjacent to one another, with the second diagram placed in the direction d from the first. The local origin of the resulting combined diagram is the same as the local origin of the first. See the documentation of beside for more information.

beside :: (Juxtaposable a, Semigroup a) => Vn a -> a -> a -> a #

Place two monoidal objects (i.e. diagrams, paths, animations...) next to each other along the given vector. In particular, place the second object so that the vector points from the local origin of the first object to the local origin of the second object, at a distance so that their envelopes are just tangent. The local origin of the new, combined object is the local origin of the first object (unless the first object is the identity element, in which case the second object is returned unchanged).

besideEx = beside (r2 (20,30))
                  (circle 1 # fc orange)
                  (circle 1.5 # fc purple)
           # showOrigin
           # centerXY # pad 1.1

Note that beside v is associative, so objects under beside v form a semigroup for any given vector v. In fact, they also form a monoid: mempty is clearly a right identity (beside v d1 mempty === d1), and there should also be a special case to make it a left identity, as described above.

In older versions of diagrams, beside put the local origin of the result at the point of tangency between the two inputs. That semantics can easily be recovered by performing an alignment on the first input before combining. That is, if beside' denotes the old semantics,

beside' v x1 x2 = beside v (x1 # align v) x2

To get something like beside v x1 x2 whose local origin is identified with that of x2 instead of x1, use beside (negateV v) x2 x1.

beneath :: (Metric v, OrderedField n, Monoid' m) => QDiagram b v n m -> QDiagram b v n m -> QDiagram b v n m infixl 6 #

beneath is just a convenient synonym for flip atop; that is, d1 `beneath` d2 is the diagram with d2 superimposed on top of d1.

intrudeEnvelope :: (Metric v, OrderedField n, Monoid' m) => v n -> QDiagram b v n m -> QDiagram b v n m #

intrudeEnvelope v d asymmetrically "intrudes" the envelope of a diagram away from the given direction. All parts of the envelope within 90 degrees of this direction are modified, offset inwards by the magnitude of the vector.

Note that this could create strange inverted envelopes, where diameter v d < 0 .

extrudeEnvelope :: (Metric v, OrderedField n, Monoid' m) => v n -> QDiagram b v n m -> QDiagram b v n m #

extrudeEnvelope v d asymmetrically "extrudes" the envelope of a diagram in the given direction. All parts of the envelope within 90 degrees of this direction are modified, offset outwards by the magnitude of the vector.

This works by offsetting the envelope distance proportionally to the cosine of the difference in angle, and leaving it unchanged when this factor is negative.

strut :: (Metric v, OrderedField n) => v n -> QDiagram b v n m #

strut v is a diagram which produces no output, but with respect to alignment and envelope acts like a 1-dimensional segment oriented along the vector v, with local origin at its center. (Note, however, that it has an empty trace; for 2D struts with a nonempty trace see strutR2 from Diagrams.TwoD.Combinators.) Useful for manually creating separation between two diagrams.

strutEx = (circle 1 ||| strut unitX ||| circle 1) # centerXY # pad 1.1

frame :: (Metric v, OrderedField n, Monoid' m) => n -> QDiagram b v n m -> QDiagram b v n m #

frame s increases the envelope of a diagram by and absolute amount s, s is in the local units of the diagram. This function is similar to pad, only it takes an absolute quantity and pre-centering should not be necessary.

pad :: (Metric v, OrderedField n, Monoid' m) => n -> QDiagram b v n m -> QDiagram b v n m #

pad s "pads" a diagram, expanding its envelope by a factor of s (factors between 0 and 1 can be used to shrink the envelope). Note that the envelope will expand with respect to the local origin, so if the origin is not centered the padding may appear "uneven". If this is not desired, the origin can be centered (using, e.g., centerXY for 2D diagrams) before applying pad.

phantom :: (InSpace v n a, Monoid' m, Enveloped a, Traced a) => a -> QDiagram b v n m #

phantom x produces a "phantom" diagram, which has the same envelope and trace as x but produces no output.

withTrace :: (InSpace v n a, Metric v, OrderedField n, Monoid' m, Traced a) => a -> QDiagram b v n m -> QDiagram b v n m #

Use the trace from some object as the trace for a diagram, in place of the diagram's default trace.

withEnvelope :: (InSpace v n a, Monoid' m, Enveloped a) => a -> QDiagram b v n m -> QDiagram b v n m #

Use the envelope from some object as the envelope for a diagram, in place of the diagram's default envelope.

sqNewEnv =
    circle 1 # fc green
    |||
    (    c # dashingG [0.1,0.1] 0 # lc white

    )
c = circle 0.8
withEnvelopeEx = sqNewEnv # centerXY # pad 1.5

data CatMethod #

Methods for concatenating diagrams.

Constructors

Cat	Normal catenation: simply put diagrams next to one another (possibly with a certain distance in between each). The distance between successive diagram envelopes will be consistent; the distance between origins may vary if the diagrams are of different sizes.
Distrib	Distribution: place the local origins of diagrams at regular intervals. With this method, the distance between successive origins will be consistent but the distance between envelopes may not be. Indeed, depending on the amount of separation, diagrams may overlap.

arcBetween p q height creates an arc beginning at p and ending at q, with its midpoint at a distance of abs height away from the straight line from p to q. A positive value of height results in an arc to the left of the line from p to q; a negative value yields one to the right.

class (Metric (V t), OrderedField (N t)) => TrailLike t where #

A type class for trail-like things, i.e. things which can be constructed from a concretely located Trail. Instances include lines, loops, trails, paths, lists of vertices, two-dimensional Diagrams, and Located variants of all the above.

Usually, type variables with TrailLike constraints are used as the output types of functions, like

  foo :: (TrailLike t) => ... -> t

Functions with such a type can be used to construct trails, paths, diagrams, lists of points, and so on, depending on the context.

To write a function with a signature like the above, you can of course call trailLike directly; more typically, one would use one of the provided functions like fromOffsets, fromVertices, fromSegments, or ~~.

Instance details Defined in Diagrams.TrailLike Methods trailLike :: Located (Trail (V (Trail v n)) (N (Trail v n))) -> Trail v n #
(Metric v, OrderedField n) => TrailLike (Trail' Line v n)	Lines are trail-like. If given a `Trail` which contains a loop, the loop will be cut with `cutLoop`. The location is ignored.
Instance details Defined in Diagrams.TrailLike Methods trailLike :: Located (Trail (V (Trail' Line v n)) (N (Trail' Line v n))) -> Trail' Line v n #
(Metric v, OrderedField n) => TrailLike (Trail' Loop v n)	Loops are trail-like. If given a `Trail` containing a line, the line will be turned into a loop using `glueLine`. The location is ignored.
Instance details Defined in Diagrams.TrailLike Methods trailLike :: Located (Trail (V (Trail' Loop v n)) (N (Trail' Loop v n))) -> Trail' Loop v n #

reverseLocLoop :: (Metric v, OrderedField n) => Located (Trail' Loop v n) -> Located (Trail' Loop v n) #

Reverse a concretely located loop. See reverseLocTrail. Note that this is guaranteed to preserve the location.

reverseLoop :: (Metric v, OrderedField n) => Trail' Loop v n -> Trail' Loop v n #

Reverse a loop. See reverseTrail.

reverseLocLine :: (Metric v, OrderedField n) => Located (Trail' Line v n) -> Located (Trail' Line v n) #

Reverse a concretely located line. See reverseLocTrail.

reverseLine :: (Metric v, OrderedField n) => Trail' Line v n -> Trail' Line v n #

Reverse a line. See reverseTrail.

reverseLocTrail :: (Metric v, OrderedField n) => Located (Trail v n) -> Located (Trail v n) #

Reverse a concretely located trail. The endpoint of the original trail becomes the starting point of the reversed trail, so the original and reversed trails comprise exactly the same set of points. reverseLocTrail is an involution, i.e.

  reverseLocTrail . reverseLocTrail === id

reverseTrail :: (Metric v, OrderedField n) => Trail v n -> Trail v n #

Reverse a trail. Semantically, if a trail given by a function t from [0,1] to vectors, then the reverse of t is given by t'(s) = t(1-s). reverseTrail is an involution, that is,

  reverseTrail . reverseTrail === id

trailLocSegments :: (Metric v, OrderedField n) => Located (Trail v n) -> [Located (Segment Closed v n)] #

Convert a concretely located trail into a list of located segments.

unfixTrail :: (Metric v, Ord n, Floating n) => [FixedSegment v n] -> Located (Trail v n) #

Convert a list of fixed segments into a located trail. Note that this may lose information: it throws away the locations of all but the first FixedSegment. This does not matter precisely when each FixedSegment begins where the previous one ends.

This is almost left inverse to fixTrail, that is, unfixTrail . fixTrail == id, except for the fact that unfixTrail will never yield a Loop. In the case of a loop, we instead have glueTrail . unfixTrail . fixTrail == id. On the other hand, it is not the case that fixTrail . unfixTrail == id since unfixTrail may lose information.

fixTrail :: (Metric v, OrderedField n) => Located (Trail v n) -> [FixedSegment v n] #

Convert a concretely located trail into a list of fixed segments. unfixTrail is almost its left inverse.

loopVertices :: (Metric v, OrderedField n) => Located (Trail' Loop v n) -> [Point v n] #

Same as loopVertices', with a default tolerance.

loopVertices' :: (Metric v, OrderedField n) => n -> Located (Trail' Loop v n) -> [Point v n] #

Extract the vertices of a concretely located loop. Note that the initial vertex is not repeated at the end. See trailVertices for more information.

lineVertices :: (Metric v, OrderedField n) => Located (Trail' Line v n) -> [Point v n] #

Like lineVertices', with a default tolerance.

lineVertices' :: (Metric v, OrderedField n) => n -> Located (Trail' Line v n) -> [Point v n] #

Extract the vertices of a concretely located line. See trailVertices for more information.

trailVertices :: (Metric v, OrderedField n) => Located (Trail v n) -> [Point v n] #

Like trailVertices', with a default tolerance.

trailVertices' :: (Metric v, OrderedField n) => n -> Located (Trail v n) -> [Point v n] #

Extract the vertices of a concretely located trail. Here a vertex is defined as a non-differentiable point on the trail, i.e. a sharp corner. (Vertices are thus a subset of the places where segments join; if you want all joins between segments, see trailPoints.) The tolerance determines how close the tangents of two segments must be at their endpoints to consider the transition point to be differentiable.

Note that for loops, the starting vertex will not be repeated at the end. If you want this behavior, you can use cutTrail to make the loop into a line first, which happens to repeat the same vertex at the start and end, e.g. with trailVertices . mapLoc cutTrail.

It does not make sense to ask for the vertices of a Trail by itself; if you want the vertices of a trail with the first vertex at, say, the origin, you can use trailVertices . (`at` origin).

lineOffset :: (Metric v, OrderedField n) => Trail' Line v n -> v n #

Compute the offset from the start of a line to the end. (Note, there is no corresponding loopOffset function because by definition it would be constantly zero.)

loopOffsets :: (Metric v, OrderedField n) => Trail' Loop v n -> [v n] #

Extract the offsets of the segments of a loop.

lineOffsets :: Trail' Line v n -> [v n] #

Extract the offsets of the segments of a line.

trailOffset :: (Metric v, OrderedField n) => Trail v n -> v n #

Compute the offset from the start of a trail to the end. Satisfies

  trailOffset === sumV . trailOffsets

but is more efficient.

trailOffsetEx = (strokeLine almostClosed <> showOffset) # centerXY # pad 1.1
  where showOffset = fromOffsets [trailOffset (wrapLine almostClosed)]
                   # strokeP # lc red

trailOffsets :: (Metric v, OrderedField n) => Trail v n -> [v n] #

Extract the offsets of the segments of a trail.

trailSegments :: (Metric v, OrderedField n) => Trail v n -> [Segment Closed v n] #

Extract the segments of a trail. If the trail is a loop it will first have cutLoop applied.

loopSegments :: Trail' Loop v n -> ([Segment Closed v n], Segment Open v n) #

Extract the segments comprising a loop: a list of closed segments, and one final open segment.

onLineSegments :: (Metric v, OrderedField n) => ([Segment Closed v n] -> [Segment Closed v n]) -> Trail' Line v n -> Trail' Line v n #

Modify a line by applying a function to its list of segments.

lineSegments :: Trail' Line v n -> [Segment Closed v n] #

Extract the segments comprising a line.

isLoop :: Trail v n -> Bool #

Determine whether a trail is a loop.

isLine :: Trail v n -> Bool #

Determine whether a trail is a line.

isTrailEmpty :: (Metric v, OrderedField n) => Trail v n -> Bool #

Test whether a trail is empty. Note that loops are never empty.

isLineEmpty :: (Metric v, OrderedField n) => Trail' Line v n -> Bool #

Test whether a line is empty.

cutTrail :: (Metric v, OrderedField n) => Trail v n -> Trail v n #

cutTrail is a variant of cutLoop for Trail; it is the is the identity on lines and performs cutLoop on loops.

cutLoop :: (Metric v, OrderedField n) => Trail' Loop v n -> Trail' Line v n #

Turn a loop into a line by "cutting" it at the common start/end point, resulting in a line which just happens to start and end at the same place.

cutLoop is right inverse to glueLine, that is,

  glueLine . cutLoop === id

closeTrail :: Trail v n -> Trail v n #

closeTrail is a variant of closeLine for Trail, which performs closeLine on lines and is the identity on loops.

closeLine :: Trail' Line v n -> Trail' Loop v n #

Make a line into a loop by adding a new linear segment from the line's end to its start.

closeLine does not have any particularly nice theoretical properties, but can be useful e.g. when you want to make a closed polygon out of a list of points where the initial point is not repeated at the end. To use glueLine, one would first have to duplicate the initial vertex, like

glueLine . lineFromVertices $ ps ++ [head ps]

Using closeLine, however, one can simply

closeLine . lineFromVertices $ ps

closeLineEx = pad 1.1 . centerXY . hcat' (with & sep .~ 1)
  $ [almostClosed # strokeLine, almostClosed # closeLine # strokeLoop]

glueTrail :: (Metric v, OrderedField n) => Trail v n -> Trail v n #

glueTrail is a variant of glueLine which works on Trails. It performs glueLine on lines and is the identity on loops.

glueLine :: (Metric v, OrderedField n) => Trail' Line v n -> Trail' Loop v n #

Make a line into a loop by "gluing" the endpoint to the starting point. In particular, the offset of the final segment is modified so that it ends at the starting point of the entire trail. Typically, you would first construct a line which you know happens to end where it starts, and then call glueLine to turn it into a loop.

glueLineEx = pad 1.1 . hsep 1
  $ [almostClosed # strokeLine, almostClosed # glueLine # strokeLoop]

almostClosed :: Trail' Line V2 Double
almostClosed = fromOffsets $ map r2 [(2, -1), (-3, -0.5), (-2, 1), (1, 0.5)]

glueLine is left inverse to cutLoop, that is,

  glueLine . cutLoop === id

trailFromVertices :: (Metric v, OrderedField n) => [Point v n] -> Trail v n #

trailFromVertices === wrapTrail . lineFromVertices, for conveniently constructing a Trail instead of a Trail' Line.

lineFromVertices :: (Metric v, OrderedField n) => [Point v n] -> Trail' Line v n #

Construct a line containing only linear segments from a list of vertices. Note that only the relative offsets between the vertices matters; the information about their absolute position will be discarded. That is, for all vectors v,

lineFromVertices === lineFromVertices . translate v

If you want to retain the position information, you should instead use the more general fromVertices function to construct, say, a Located (Trail' Line v) or a Located (Trail v).

import Diagrams.Coordinates
lineFromVerticesEx = pad 1.1 . centerXY . strokeLine
  $ lineFromVertices [origin, 0 ^& 1, 1 ^& 2, 5 ^& 1]

trailFromOffsets :: (Metric v, OrderedField n) => [v n] -> Trail v n #

trailFromOffsets === wrapTrail . lineFromOffsets, for conveniently constructing a Trail instead of a Trail' Line.

lineFromOffsets :: (Metric v, OrderedField n) => [v n] -> Trail' Line v n #

Construct a line containing only linear segments from a list of vectors, where each vector represents the offset from one vertex to the next. See also fromOffsets.

import Diagrams.Coordinates
lineFromOffsetsEx = strokeLine $ lineFromOffsets [ 2 ^& 1, 2 ^& (-1), 2 ^& 0.5 ]

trailFromSegments :: (Metric v, OrderedField n) => [Segment Closed v n] -> Trail v n #

trailFromSegments === wrapTrail . lineFromSegments, for conveniently constructing a Trail instead of a Trail'.

loopFromSegments :: (Metric v, OrderedField n) => [Segment Closed v n] -> Segment Open v n -> Trail' Loop v n #

Construct a loop from a list of closed segments and an open segment that completes the loop.

lineFromSegments :: (Metric v, OrderedField n) => [Segment Closed v n] -> Trail' Line v n #

Construct a line from a list of closed segments.

emptyTrail :: (Metric v, OrderedField n) => Trail v n #

A wrapped variant of emptyLine.

emptyLine :: (Metric v, OrderedField n) => Trail' Line v n #

The empty line, which is the identity for concatenation of lines.

wrapLoop :: Trail' Loop v n -> Trail v n #

Convert a loop into a Trail. This is the same as wrapTrail, but with a more specific type, which can occasionally be convenient for fixing the type of a polymorphic expression.

wrapLine :: Trail' Line v n -> Trail v n #

Convert a line into a Trail. This is the same as wrapTrail, but with a more specific type, which can occasionally be convenient for fixing the type of a polymorphic expression.

wrapTrail :: Trail' l v n -> Trail v n #

Convert a Trail' into a Trail, hiding the type-level distinction between lines and loops.

onLine :: (Metric v, OrderedField n) => (Trail' Line v n -> Trail' Line v n) -> Trail v n -> Trail v n #

Modify a Trail by specifying a transformation on lines. If the trail is a line, the transformation will be applied directly. If it is a loop, it will first be cut using cutLoop, the transformation applied, and then glued back into a loop with glueLine. That is,

  onLine f === onTrail f (glueLine . f . cutLoop)

Note that there is no corresponding onLoop function, because there is no nice way in general to convert a line into a loop, operate on it, and then convert back.

withLine :: (Metric v, OrderedField n) => (Trail' Line v n -> r) -> Trail v n -> r #

An eliminator for Trail based on eliminating lines: if the trail is a line, the given function is applied; if it is a loop, it is first converted to a line with cutLoop. That is,

withLine f === withTrail f (f . cutLoop)

onTrail :: (Trail' Line v n -> Trail' l1 v n) -> (Trail' Loop v n -> Trail' l2 v n) -> Trail v n -> Trail v n #

Modify a Trail, specifying two separate transformations for the cases of a line or a loop.

withTrail :: (Trail' Line v n -> r) -> (Trail' Loop v n -> r) -> Trail v n -> r #

A generic eliminator for Trail, taking functions specifying what to do in the case of a line or a loop.

_LocLoop :: Prism' (Located (Trail v n)) (Located (Trail' Loop v n)) #

Prism onto a Located Loop.

_LocLine :: Prism' (Located (Trail v n)) (Located (Trail' Line v n)) #

Prism onto a Located Line.

_Loop :: Prism' (Trail v n) (Trail' Loop v n) #

Prism onto a Loop.

_Line :: Prism' (Trail v n) (Trail' Line v n) #

Prism onto a Line.

getSegment :: t -> GetSegment t #

Create a GetSegment wrapper around a trail, after which you can call atParam, atStart, or atEnd to extract a segment.

withTrail' :: (Trail' Line v n -> r) -> (Trail' Loop v n -> r) -> Trail' l v n -> r #

A generic eliminator for Trail', taking functions specifying what to do in the case of a line or a loop.

offset :: (OrderedField n, Metric v, Measured (SegMeasure v n) t) => t -> v n #

Compute the total offset of anything measured by SegMeasure.

numSegs :: (Num c, Measured (SegMeasure v n) a) => a -> c #

Compute the number of segments of anything measured by SegMeasure (e.g. SegMeasure itself, Segment, SegTree, Trails...)

trailMeasure :: (SegMeasure v n :>: m, Measured (SegMeasure v n) t) => a -> (m -> a) -> t -> a #

Given a default result (to be used in the case of an empty trail), and a function to map a single measure to a result, extract the given measure for a trail and use it to compute a result. Put another way, lift a function on a single measure (along with a default value) to a function on an entire trail.

newtype SegTree (v :: Type -> Type) n #

A SegTree represents a sequence of closed segments, stored in a fingertree so we can easily recover various monoidal measures of the segments (number of segments, arc length, envelope...) and also easily slice and dice them according to the measures (e.g., split off the smallest number of segments from the beginning which have a combined arc length of at least 5).

Intuitively, a trail is a single, continuous path through space. However, a trail has no fixed starting point; it merely specifies how to move through space, not where. For example, "take three steps forward, then turn right twenty degrees and take two more steps" is an intuitive analog of a trail; these instructions specify a path through space from any given starting location. To be precise, trails are translation-invariant; applying a translation to a trail has no effect.

A Located Trail, on the other hand, is a trail paired with some concrete starting location ("start at the big tree on the corner, then take three steps forward, ..."). See the Diagrams.Located module for help working with Located values.

Formally, the semantics of a trail is a continuous (though not necessarily differentiable) function from the real interval [0,1] to vectors in some vector space. (In contrast, a Located trail is a continuous function from [0,1] to points in some affine space.)

There are two types of trails:

A "line" (think of the "train", "subway", or "bus" variety, rather than the "straight" variety...) is a trail with two distinct endpoints. Actually, a line can have the same start and end points, but it is still drawn as if it had distinct endpoints: the two endpoints will have the appropriate end caps, and the trail will not be filled. Lines have a Monoid instance where mappend corresponds to concatenation, i.e. chaining one line after the other.
A "loop" is required to end in the same place it starts (that is, t(0) = t(1)). Loops are filled and are drawn as one continuous loop, with the appropriate join at the start/endpoint rather than end caps. Loops do not have a Monoid instance.

To convert between lines and loops, see glueLine, closeLine, and cutLoop.

To construct trails, see emptyTrail, trailFromSegments, trailFromVertices, trailFromOffsets, and friends. You can also get any type of trail from any function which returns a TrailLike (e.g. functions in Diagrams.TwoD.Shapes, and many others; see Diagrams.TrailLike).

To extract information from trails, see withLine, isLoop, trailSegments, trailOffsets, trailVertices, and friends.

newtype GetSegment t #

A newtype wrapper around trails which exists solely for its Parametric, DomainBounds and EndValues instances. The idea is that if tr is a trail, you can write, e.g.

  getSegment tr atParam 0.6

or

  atStart (getSegment tr)

to get the segment at parameter 0.6 or the first segment in the trail, respectively.

The codomain for GetSegment, i.e. the result you get from calling atParam, atStart, or atEnd, is GetSegmentCodomain, which is a newtype wrapper around Maybe (v, Segment Closed v, AnIso' n n). Nothing results if the trail is empty; otherwise, you get:

the offset from the start of the trail to the beginning of the segment,
the segment itself, and
a reparameterization isomorphism: in the forward direction, it translates from parameters on the whole trail to a parameters on the segment. Note that for technical reasons you have to call cloneIso on the AnIso' value to get a real isomorphism you can use.

The atomic constituents of the concrete representation currently used for trails are segments, currently limited to single straight lines or cubic Bézier curves. Segments are translationally invariant, that is, they have no particular "location" and are unaffected by translations. They are, however, affected by other transformations such as rotations and scales.

Linear !(Offset c v n)	A linear segment with given offset.
Cubic !(v n) !(v n) !(Offset c v n)	A cubic Bézier segment specified by three offsets from the starting point to the first control point, second control point, and ending point, respectively.

_loc :: Lens' (Located a) (Point (V a) (N a)) #

Lens onto the location of something Located.

located :: SameSpace a b => Lens (Located a) (Located b) a b #

A lens giving access to the object within a Located wrapper.

mapLoc :: SameSpace a b => (a -> b) -> Located a -> Located b #

Located is not a Functor, since changing the type could change the type of the associated vector space, in which case the associated location would no longer have the right type. mapLoc has an extra constraint specifying that the vector space must stay the same.

(Technically, one can say that for every vector space v, Located is a little-f (endo)functor on the category of types with associated vector space v; but that is not covered by the standard Functor class.)

viewLoc :: Located a -> (Point (V a) (N a), a) #

Deconstruct a Located a into a location and a value of type a. viewLoc can be especially useful in conjunction with the ViewPatterns extension.

at :: a -> Point (V a) (N a) -> Located a infix 5 #

Construct a Located a from a value of type a and a location. at is intended to be used infix, like x `at` origin.

data Located a #

"Located" things, i.e. things with a concrete location: intuitively, Located a ~ (Point, a). Wrapping a translationally invariant thing (e.g. a Segment or Trail) in Located pins it down to a particular location and makes it no longer translationally invariant.

Located is intentionally abstract. To construct Located values, use at. To destruct, use viewLoc, unLoc, or loc. To map, use mapLoc.

Much of the utility of having a concrete type for the Located concept lies in the type class instances we can give it. The HasOrigin, Transformable, Enveloped, Traced, and TrailLike instances are particularly useful; see the documented instances below for more information.

Constructors

Loc
Fields loc :: Point (V a) (N a) Project out the location of a `Located` value. unLoc :: a Project the value of type `a` out of a `Located a`, discarding the location.

Methods

alignBy' :: (InSpace v n a, Fractional n, HasOrigin a) => (v n -> a -> Point v n) -> v n -> n -> a -> a #

alignBy v d a moves the origin of a along the vector v. If d = 1, the origin is moved to the edge of the boundary in the direction of v; if d = -1, it moves to the edge of the boundary in the direction of the negation of v. Other values of d interpolate linearly (so for example, d = 0 centers the origin along the direction of v).

globalPackage :: IO FilePath #

Find ghc's global package database. Throws an error if it isn't found.

findSandbox :: [FilePath] -> IO (Maybe FilePath) #

Search for a sandbox in the following order:

Test given FilePaths if they point directly to a database or contain a cabal config file (or any parent directory containing a config file).
Same test for DIAGRAMS_SANDBOX environment value
Environment values of GHC_PACKAGE_PATH, HSENV and PACKAGE_DB_FOR_GHC that point to a database.
Test for config file (cabal.sandbox.config) in the current directory and its parents.

findHsFile :: FilePath -> IO (Maybe FilePath) #

Given some file (no extension or otherwise) try to find a haskell source file.

foldB :: (a -> a -> a) -> a -> [a] -> a #

Given an associative binary operation and a default value to use in the case of an empty list, perform a balanced fold over a list. For example,

  foldB (+) z [a,b,c,d,e,f] == ((a+b) + (c+d)) + (e+f)

tau :: Floating a => a #

The circle constant, the ratio of a circle's circumference to its radius. Note that pi = tau/2.

For more information and a well-reasoned argument why we should all be using tau instead of pi, see The Tau Manifesto, http://tauday.com/.

iterateN :: Int -> (a -> a) -> a -> [a] #

iterateN n f x returns the list of the first n iterates of f starting at x, that is, the list [x, f x, f (f x), ...] of length n. (Note that the last element of the list will be f applied to x (n-1) times.)

(##) :: AReview t b -> b -> t infixr 8 #

A replacement for lenses' # operator.

(#) :: a -> (a -> b) -> b infixl 8 #

Postfix function application, for conveniently applying attributes. Unlike ($), (#) has a high precedence (8), so d # foo # bar can be combined with other things using operators like (|||) or (<>) without needing parentheses.

applyAll :: [a -> a] -> a -> a #

applyAll takes a list of functions and applies them all to a value, in sequence from the last function in the list to the first. For example, applyAll [f1, f2, f3] a == f1 . f2 . f3 $ a.

with :: Default d => d #

Several functions exported by the diagrams library take a number of arguments giving the user control to "tweak" various aspects of their behavior. Rather than give such functions a long list of arguments, and to make it possible for the user to selectively override only certain arguments and use default values for others, such sets of arguments are collected into a record with named fields (see PolygonOpts in Diagrams.TwoD.Shapes for an example). Such record types are made instances of the Default class, which provides a single record structure (def) collecting the "default" arguments to the function. with is a synonym for def, which provides nice-looking syntax for simulating optional, named arguments in Haskell. For example,

  polygon with {sides = 7, edgeSkip = 2}

calls the polygon function with a single argument (note that record update binds more tightly than function application!), namely, with (the record of default arguments) where the sides and edgeSkip fields have been updated.

translated :: (InSpace v n a, SameSpace a b, Transformable a, Transformable b) => v n -> Iso a b a b #

Use a vector to make an Iso between an object translated and untranslated.

under (translated v) f == translate (-v) . f . translate v
translated v ## a      == translate v a
a ^. translated v      == translate (-v) a
over (translated v) f  == translate v . f . translate (-v)

movedFrom :: (InSpace v n a, SameSpace a b, HasOrigin a, HasOrigin b) => Point v n -> Iso a b a b #

Use a Transformation to make an Iso between an object transformed and untransformed. We have

under (movedFrom p) f == moveTo p . f . moveTo (-p)
movedFrom p           == from (movedTo p)
movedFrom p ## a      == moveOriginTo p a
a ^. movedFrom p      == moveTo p a
over (movedFrom p) f  == moveTo (-p) . f . moveTo p

movedTo :: (InSpace v n a, SameSpace a b, HasOrigin a, HasOrigin b) => Point v n -> Iso a b a b #

transformed :: (InSpace v n a, SameSpace a b, Transformable a, Transformable b) => Transformation v n -> Iso a b a b #

Use a Transformation to make an Iso between an object transformed and untransformed. This is useful for carrying out functions under another transform:

under (transformed t) f               == transform (inv t) . f . transform t
under (transformed t1) (transform t2) == transform (conjugate t1 t2)
transformed t ## a                    == transform t a
a ^. transformed t                    == transform (inv t) a

underT :: (InSpace v n a, SameSpace a b, Transformable a, Transformable b) => (a -> b) -> Transformation v n -> a -> b #

Carry out some transformation "under" another one: f `underT` t first applies t, then f, then the inverse of t. For example, scaleX 2 `underT` rotation (-1/8 @@ Turn) is the transformation which scales by a factor of 2 along the diagonal line y = x.

Note that

(transform t2) underT t1 == transform (conjugate t1 t2)

for all transformations t1 and t2.

See also the isomorphisms like transformed, movedTo, movedFrom, and translated.

data Specular #

A specular highlight has two terms, the intensity, between 0 and 1, and the size. The highlight size is assumed to be the exponent in a Phong shading model (though Backends are free to use a different shading model). In this model, reasonable values are between 1 and 50 or so, with higher values for shinier objects. Physically, the intensity and the value of Diffuse must add up to less than 1; this is not enforced.

rotate :: (InSpace V2 n t, Transformable t, Floating n) => Angle n -> t -> t #

Rotate about the local origin by the given angle. Positive angles correspond to counterclockwise rotation, negative to clockwise. The angle can be expressed using any of the Isos on Angle. For example, rotate (1/4 @@ turn), rotate (tau/4 @@ rad), and rotate (90 @@ deg) all represent the same transformation, namely, a counterclockwise rotation by a right angle. To rotate about some point other than the local origin, see rotateAbout.

Note that writing rotate (1/4), with no Angle constructor, will yield an error since GHC cannot figure out which sort of angle you want to use. In this common situation you can use rotateBy, which interprets its argument as a number of turns.

rotation :: Floating n => Angle n -> Transformation V2 n #

Create a transformation which performs a rotation about the local origin by the given angle. See also rotate.

normalizeAngle :: (Floating n, Real n) => Angle n -> Angle n #

Normalize an angle so that it lies in the [0,tau) range.

angleBetween :: (Metric v, Floating n, Ord n) => v n -> v n -> Angle n #

Compute the positive angle between the two vectors in their common plane in the [0,pi] range. For a signed angle see signedAngleBetween.

Returns NaN if either of the vectors are zero.

class DomainBounds p => Sectionable p where #

Type class for parametric objects which can be split into subobjects.

Minimal definition: Either splitAtParam or section, plus reverseDomain.

Minimal complete definition

reverseDomain

Methods

splitAtParam :: p -> N p -> (p, p) #

splitAtParam splits an object p into two new objects (l,r) at the parameter t, where l corresponds to the portion of p for parameter values from 0 to t and r for to that from t to 1. The following property should hold:

  prop_splitAtParam f t u =
    | u < t     = atParam f u == atParam l (u / t)
    | otherwise = atParam f u == atParam f t ??? atParam l ((u - t) / (domainUpper f - t))
    where (l,r) = splitAtParam f t

where (???) = (^+^) if the codomain is a vector type, or const flip if the codomain is a point type. Stated more intuitively, all this is to say that the parameterization scales linearly with splitting.

splitAtParam can also be used with parameters outside the range of the domain. For example, using the parameter 2 with a path (where the domain is the default [0,1]) gives two result paths where the first is the original path extended to the parameter 2, and the second result path travels backwards from the end of the first to the end of the original path.

section :: p -> N p -> N p -> p #

Extract a particular section of the domain, linearly reparameterized to the same domain as the original. Should satisfy the property:

prop_section x l u t =
  let s = section x l u
  in     domainBounds x == domainBounds x
      && (x `atParam` lerp l u t) == (s `atParam` t)

That is, the section should have the same domain as the original, and the reparameterization should be linear.

reverseDomain :: p -> p #

Flip the parameterization on the domain.

(Metric v, OrderedField n, Real n) => Sectionable (Trail v n)	Note that there is no `Sectionable` instance for `Trail' Loop`, because it does not make sense (splitting a loop at a parameter results in a single line, not two loops). However, it's convenient to have a `Sectionable` instance for `Trail`; if the `Trail` contains a loop the loop will first be cut and then `splitAtParam` called on the resulting line. This is semantically a bit silly, so please don't rely on it. (E.g. if this is really the behavior you want, consider first calling `cutLoop` yourself.)

Type class for parametric things with a notion of arc length.

Minimal complete definition

arcLengthBounded, arcLengthToParam

Methods

arcLengthBounded :: N p -> p -> Interval (N p) #

arcLengthBounded eps x approximates the arc length of x. The true arc length is guaranteed to lie within the interval returned, which will have a size of at most eps.

arcLength :: N p -> p -> N p #

arcLength eps s approximates the arc length of x up to the accuracy eps (plus or minus).

stdArcLength :: p -> N p #

Approximate the arc length up to a standard accuracy of stdTolerance (1e-6).

arcLengthToParam :: N p -> p -> N p -> N p #

arcLengthToParam eps s l converts the absolute arc length l, measured from the start of the domain, to a parameter on the object s. The true arc length at the parameter returned is guaranteed to be within eps of the requested arc length.

This should work for any arc length, and may return any parameter value (not just parameters in the domain).

stdArcLengthToParam :: p -> N p -> N p #

A simple interface to convert arc length to a parameter, guaranteed to be accurate within stdTolerance, or 1e-6.

class Color c where #

The Color type class encompasses color representations which can be used by the Diagrams library. Instances are provided for both the Colour and AlphaColour types from the Data.Colour library.

Methods

toAlphaColour :: c -> AlphaColour Double #

Convert a color to its standard representation, AlphaColour.

data Opacity #

Although the individual colors in a diagram can have transparency, the opacity/transparency of a diagram as a whole can be specified with the Opacity attribute. The opacity is a value between 1 (completely opaque, the default) and 0 (completely transparent). Opacity is multiplicative, that is, opacity o1 . opacity o2 === opacity (o1 * o2). In other words, for example, opacity 0.8 means "decrease this diagram's opacity to 80% of its previous opacity".

Methods

distrib :: Functor f => p a b -> p (f a) (f b) #

Conjoined is strong enough to let us distribute every Conjoined Profunctor over every Haskell Functor. This is effectively a generalization of fmap.

conjoined :: ((p ~ ((->) :: Type -> Type -> Type)) -> q (a -> b) r) -> q (p a b) r -> q (p a b) r #

This permits us to make a decision at an outermost point about whether or not we use an index.

Ideally any use of this function should be done in such a way so that you compute the same answer, but this cannot be enforced at the type level.

Fold a container with indices returning both the indices and the values.

The result is only valid to compose in a Traversal, if you don't edit the index as edits to the index have no effect.

>>> [10, 20, 30] ^.. ifolded . withIndex
[(0,10),(1,20),(2,30)]

[(0,"10"),(-1,"20"),(-2,"30")]

asIndex :: (Indexable i p, Contravariant f, Functor f) => p i (f i) -> Indexed i s (f s) #

When composed with an IndexedFold or IndexedTraversal this yields an (Indexed) Fold of the indices.

type Context' a = Context a a #

type Context' a s = Context a a s

data Context a b t #

The indexed store can be used to characterize a Lens and is used by cloneLens.

Context a b t is isomorphic to newtype Context a b t = Context { runContext :: forall f. Functor f => (a -> f b) -> f t }, and to exists s. (s, Lens s t a b).

A Context is like a Lens that has already been applied to a some structure.

data Level i a #

This data type represents a path-compressed copy of one level of a source data structure. We can safely use path-compression because we know the depth of the tree.

Path compression is performed by viewing a Level as a PATRICIA trie of the paths into the structure to leaves at a given depth, similar in many ways to a IntMap, but unlike a regular PATRICIA trie we do not need to store the mask bits merely the depth of the fork.

One invariant of this structure is that underneath a Two node you will not find any Zero nodes, so Zero can only occur at the root.

type Over' (p :: Type -> Type -> Type) (f :: Type -> Type) s a = Over p f s s a a #

This is a convenient alias for use when you need to consume either indexed or non-indexed lens-likes based on context.

type Over' p f = Simple (Over p f)

type Over (p :: k -> Type -> Type) (f :: k1 -> Type) s (t :: k1) (a :: k) (b :: k1) = p a (f b) -> s -> f t #

This is a convenient alias for use when you need to consume either indexed or non-indexed lens-likes based on context.

type IndexedLensLike' i (f :: Type -> Type) s a = IndexedLensLike i f s s a a #

Convenient alias for constructing simple indexed lenses and their ilk.

type IndexedLensLike i (f :: k -> Type) s (t :: k) a (b :: k) = forall (p :: Type -> Type -> Type). Indexable i p => p a (f b) -> s -> f t #

Convenient alias for constructing indexed lenses and their ilk.

type LensLike' (f :: Type -> Type) s a = LensLike f s s a a #

type LensLike' f = Simple (LensLike f)

type LensLike (f :: k -> Type) s (t :: k) a (b :: k) = (a -> f b) -> s -> f t #

Many combinators that accept a Lens can also accept a Traversal in limited situations.

They do so by specializing the type of Functor that they require of the caller.

If a function accepts a LensLike f s t a b for some Functor f, then they may be passed a Lens.

Further, if f is an Applicative, they may also be passed a Traversal.

type Optical' (p :: k1 -> k -> Type) (q :: k1 -> k -> Type) (f :: k1 -> k) (s :: k1) (a :: k1) = Optical p q f s s a a #

type Optical' p q f s a = Simple (Optical p q f) s a

type Optical (p :: k2 -> k -> Type) (q :: k1 -> k -> Type) (f :: k3 -> k) (s :: k1) (t :: k3) (a :: k2) (b :: k3) = p a (f b) -> q s (f t) #

type LensLike f s t a b = Optical (->) (->) f s t a b

type Over p f s t a b = Optical p (->) f s t a b

type Optic p f s t a b = Optical p p f s t a b

type Optic' (p :: k1 -> k -> Type) (f :: k1 -> k) (s :: k1) (a :: k1) = Optic p f s s a a #

type Optic' p f s a = Simple (Optic p f) s a

type Optic (p :: k1 -> k -> Type) (f :: k2 -> k) (s :: k1) (t :: k2) (a :: k1) (b :: k2) = p a (f b) -> p s (f t) #

A valid Optic l should satisfy the laws:

l pure ≡ pure
l (Procompose f g) = Procompose (l f) (l g)

This gives rise to the laws for Equality, Iso, Prism, Lens, Traversal, Traversal1, Setter, Fold, Fold1, and Getter as well along with their index-preserving variants.

type LensLike f s t a b = Optic (->) f s t a b

type Simple (f :: k -> k -> k1 -> k1 -> k2) (s :: k) (a :: k1) = f s s a a #

A Simple Lens, Simple Traversal, ... can be used instead of a Lens,Traversal, ... whenever the type variables don't change upon setting a value.

_imagPart :: Simple Lens (Complex a) a
traversed :: Simple (IndexedTraversal Int) [a] a

Note: To use this alias in your own code with LensLike f or Setter, you may have to turn on LiberalTypeSynonyms.

This is commonly abbreviated as a "prime" marker, e.g. Lens' = Simple Lens.

type IndexPreservingFold1 s a = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Conjoined p, Contravariant f, Apply f) => p a (f a) -> p s (f s) #

type IndexedFold1 i s a = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Indexable i p, Contravariant f, Apply f) => p a (f a) -> s -> f s #

type Fold1 s a = forall (f :: Type -> Type). (Contravariant f, Apply f) => (a -> f a) -> s -> f s #

A relevant Fold (aka Fold1) has one or more targets.

type IndexPreservingFold s a = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Conjoined p, Contravariant f, Applicative f) => p a (f a) -> p s (f s) #

An IndexPreservingFold can be used as a Fold, but when composed with an IndexedTraversal, IndexedFold, or IndexedLens yields an IndexedFold respectively.

type IndexedFold i s a = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Indexable i p, Contravariant f, Applicative f) => p a (f a) -> s -> f s #

Every IndexedFold is a valid Fold and can be used for Getting.

type Fold s a = forall (f :: Type -> Type). (Contravariant f, Applicative f) => (a -> f a) -> s -> f s #

A Fold describes how to retrieve multiple values in a way that can be composed with other LensLike constructions.

A Fold s a provides a structure with operations very similar to those of the Foldable typeclass, see foldMapOf and the other Fold combinators.

By convention, if there exists a foo method that expects a Foldable (f a), then there should be a fooOf method that takes a Fold s a and a value of type s.

A Getter is a legal Fold that just ignores the supplied Monoid.

Unlike a Traversal a Fold is read-only. Since a Fold cannot be used to write back there are no Lens laws that apply.

type IndexPreservingGetter s a = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Conjoined p, Contravariant f, Functor f) => p a (f a) -> p s (f s) #

An IndexPreservingGetter can be used as a Getter, but when composed with an IndexedTraversal, IndexedFold, or IndexedLens yields an IndexedFold, IndexedFold or IndexedGetter respectively.

type IndexedGetter i s a = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Indexable i p, Contravariant f, Functor f) => p a (f a) -> s -> f s #

Every IndexedGetter is a valid IndexedFold and can be used for Getting like a Getter.

type Getter s a = forall (f :: Type -> Type). (Contravariant f, Functor f) => (a -> f a) -> s -> f s #

A Getter describes how to retrieve a single value in a way that can be composed with other LensLike constructions.

Unlike a Lens a Getter is read-only. Since a Getter cannot be used to write back there are no Lens laws that can be applied to it. In fact, it is isomorphic to an arbitrary function from (s -> a).

Moreover, a Getter can be used directly as a Fold, since it just ignores the Applicative.

type As (a :: k2) = Equality' a a #

Composable asTypeOf. Useful for constraining excess polymorphism, foo . (id :: As Int) . bar.

type Equality' (s :: k2) (a :: k2) = Equality s s a a #

A Simple Equality.

type Equality (s :: k1) (t :: k2) (a :: k1) (b :: k2) = forall k3 (p :: k1 -> k3 -> Type) (f :: k2 -> k3). p a (f b) -> p s (f t) #

A witness that (a ~ s, b ~ t).

Note: Composition with an Equality is index-preserving.

type Prism' s a = Prism s s a a #

A Simple Prism.

type Prism s t a b = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Choice p, Applicative f) => p a (f b) -> p s (f t) #

A Prism l is a Traversal that can also be turned around with re to obtain a Getter in the opposite direction.

There are three laws that a Prism should satisfy:

First, if I re or review a value with a Prism and then preview or use (^?), I will get it back:

preview l (review l b) ≡ Just b

Second, if you can extract a value a using a Prism l from a value s, then the value s is completely described by l and a:

preview l s ≡ Just a ⟹ review l a ≡ s

Third, if you get non-match t, you can convert it result back to s:

matching l s ≡ Left t ⟹ matching l t ≡ Left s

The first two laws imply that the Traversal laws hold for every Prism and that we traverse at most 1 element:

lengthOf l x <= 1

It may help to think of this as a Iso that can be partial in one direction.

Every Prism is a valid Traversal.

Every Iso is a valid Prism.

For example, you might have a Prism' Integer Natural allows you to always go from a Natural to an Integer, and provide you with tools to check if an Integer is a Natural and/or to edit one if it is.

nat :: Prism' Integer Natural
nat = prism toInteger $ \ i ->
   if i < 0
   then Left i
   else Right (fromInteger i)

Now we can ask if an Integer is a Natural.

>>> 5^?nat
Just 5

>>> (-5)^?nat
Nothing

We can update the ones that are:

>>> (-3,4) & both.nat *~ 2
(-3,8)

And we can then convert from a Natural to an Integer.

>>> 5 ^. re nat -- :: Natural
5

Similarly we can use a Prism to traverse the Left half of an Either:

>>> Left "hello" & _Left %~ length
Left 5

or to construct an Either:

>>> 5^.re _Left
Left 5

such that if you query it with the Prism, you will get your original input back.

>>> 5^.re _Left ^? _Left
Just 5

Another interesting way to think of a Prism is as the categorical dual of a Lens -- a co-Lens, so to speak. This is what permits the construction of outside.

Note: Composition with a Prism is index-preserving.

type AReview t b = Optic' (Tagged :: Type -> Type -> Type) Identity t b #

If you see this in a signature for a function, the function is expecting a Review (in practice, this usually means a Prism).

type Review t b = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Choice p, Bifunctor p, Settable f) => Optic' p f t b #

This is a limited form of a Prism that can only be used for re operations.

Like with a Getter, there are no laws to state for a Review.

You can generate a Review by using unto. You can also use any Prism or Iso directly as a Review.

type Iso' s a = Iso s s a a #

type Iso' = Simple Iso

type Iso s t a b = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Profunctor p, Functor f) => p a (f b) -> p s (f t) #

Isomorphism families can be composed with another Lens using (.) and id.

Since every Iso is both a valid Lens and a valid Prism, the laws for those types imply the following laws for an Iso f:

f . from f ≡ id
from f . f ≡ id

Note: Composition with an Iso is index- and measure- preserving.

type IndexPreservingSetter' s a = IndexPreservingSetter s s a a #

type IndexedPreservingSetter' i = Simple IndexedPreservingSetter

type IndexPreservingSetter s t a b = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Conjoined p, Settable f) => p a (f b) -> p s (f t) #

An IndexPreservingSetter can be composed with a IndexedSetter, IndexedTraversal or IndexedLens and leaves the index intact, yielding an IndexedSetter.

type IndexedSetter' i s a = IndexedSetter i s s a a #

type IndexedSetter' i = Simple (IndexedSetter i)

type IndexedSetter i s t a b = forall (f :: Type -> Type) (p :: Type -> Type -> Type). (Indexable i p, Settable f) => p a (f b) -> s -> f t #

Every IndexedSetter is a valid Setter.

The Setter laws are still required to hold.

type Setter' s a = Setter s s a a #

A Setter' is just a Setter that doesn't change the types.

These are particularly common when talking about monomorphic containers. e.g.

sets Data.Text.map :: Setter' Text Char

type Setter' = Simple Setter

type Setter s t a b = forall (f :: Type -> Type). Settable f => (a -> f b) -> s -> f t #

The only LensLike law that can apply to a Setter l is that

set l y (set l x a) ≡ set l y a

You can't view a Setter in general, so the other two laws are irrelevant.

However, two Functor laws apply to a Setter:

over l id ≡ id
over l f . over l g ≡ over l (f . g)

These can be stated more directly:

l pure ≡ pure
l f . untainted . l g ≡ l (f . untainted . g)

You can compose a Setter with a Lens or a Traversal using (.) from the Prelude and the result is always only a Setter and nothing more.

>>> over traverse f [a,b,c,d]
[f a,f b,f c,f d]

>>> over _1 f (a,b)
(f a,b)

>>> over (traverse._1) f [(a,b),(c,d)]
[(f a,b),(f c,d)]

>>> over both f (a,b)
(f a,f b)

>>> over (traverse.both) f [(a,b),(c,d)]
[(f a,f b),(f c,f d)]

type IndexPreservingTraversal1' s a = IndexPreservingTraversal1 s s a a #

type IndexPreservingTraversal1 s t a b = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Conjoined p, Apply f) => p a (f b) -> p s (f t) #

type IndexPreservingTraversal' s a = IndexPreservingTraversal s s a a #

type IndexPreservingTraversal' = Simple IndexPreservingTraversal

type IndexPreservingTraversal s t a b = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Conjoined p, Applicative f) => p a (f b) -> p s (f t) #

An IndexPreservingLens leaves any index it is composed with alone.

type IndexedTraversal1' i s a = IndexedTraversal1 i s s a a #

type IndexedTraversal1 i s t a b = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Indexable i p, Apply f) => p a (f b) -> s -> f t #

type IndexedTraversal' i s a = IndexedTraversal i s s a a #

type IndexedTraversal' i = Simple (IndexedTraversal i)

type IndexedTraversal i s t a b = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Indexable i p, Applicative f) => p a (f b) -> s -> f t #

Every IndexedTraversal is a valid Traversal or IndexedFold.

The Indexed constraint is used to allow an IndexedTraversal to be used directly as a Traversal.

The Traversal laws are still required to hold.

In addition, the index i should satisfy the requirement that it stays unchanged even when modifying the value a, otherwise traversals like indices break the Traversal laws.

type Traversal1' s a = Traversal1 s s a a #

type Traversal1 s t a b = forall (f :: Type -> Type). Apply f => (a -> f b) -> s -> f t #

type Traversal' s a = Traversal s s a a #

type Traversal' = Simple Traversal

type Traversal s t a b = forall (f :: Type -> Type). Applicative f => (a -> f b) -> s -> f t #

A Traversal can be used directly as a Setter or a Fold (but not as a Lens) and provides the ability to both read and update multiple fields, subject to some relatively weak Traversal laws.

These have also been known as multilenses, but they have the signature and spirit of

traverse :: Traversable f => Traversal (f a) (f b) a b

and the more evocative name suggests their application.

Most of the time the Traversal you will want to use is just traverse, but you can also pass any Lens or Iso as a Traversal, and composition of a Traversal (or Lens or Iso) with a Traversal (or Lens or Iso) using (.) forms a valid Traversal.

The laws for a Traversal t follow from the laws for Traversable as stated in "The Essence of the Iterator Pattern".

t pure ≡ pure
fmap (t f) . t g ≡ getCompose . t (Compose . fmap f . g)

One consequence of this requirement is that a Traversal needs to leave the same number of elements as a candidate for subsequent Traversal that it started with. Another testament to the strength of these laws is that the caveat expressed in section 5.5 of the "Essence of the Iterator Pattern" about exotic Traversable instances that traverse the same entry multiple times was actually already ruled out by the second law in that same paper!

type IndexPreservingLens' s a = IndexPreservingLens s s a a #

type IndexPreservingLens' = Simple IndexPreservingLens

type IndexPreservingLens s t a b = forall (p :: Type -> Type -> Type) (f :: Type -> Type). (Conjoined p, Functor f) => p a (f b) -> p s (f t) #

An IndexPreservingLens leaves any index it is composed with alone.

type IndexedLens' i s a = IndexedLens i s s a a #

type IndexedLens' i = Simple (IndexedLens i)

type IndexedLens i s t a b = forall (f :: Type -> Type) (p :: Type -> Type -> Type). (Indexable i p, Functor f) => p a (f b) -> s -> f t #

Every IndexedLens is a valid Lens and a valid IndexedTraversal.

type Lens' s a = Lens s s a a #

type Lens' = Simple Lens

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

A Lens is actually a lens family as described in http://comonad.com/reader/2012/mirrored-lenses/.

With great power comes great responsibility and a Lens is subject to the three common sense Lens laws:

1) You get back what you put in:

view l (set l v s)  ≡ v

2) Putting back what you got doesn't change anything:

set l (view l s) s  ≡ s

3) Setting twice is the same as setting once:

set l v' (set l v s) ≡ set l v' s

These laws are strong enough that the 4 type parameters of a Lens cannot vary fully independently. For more on how they interact, read the "Why is it a Lens Family?" section of http://comonad.com/reader/2012/mirrored-lenses/.

There are some emergent properties of these laws:

1) set l s must be injective for every s This is a consequence of law #1

2) set l must be surjective, because of law #2, which indicates that it is possible to obtain any v from some s such that set s v = s

3) Given just the first two laws you can prove a weaker form of law #3 where the values v that you are setting match:

set l v (set l v s) ≡ set l v s

Every Lens can be used directly as a Setter or Traversal.

You can also use a Lens for Getting as if it were a Fold or Getter.

Since every Lens is a valid Traversal, the Traversal laws are required of any Lens you create:

l pure ≡ pure
fmap (l f) . l g ≡ getCompose . l (Compose . fmap f . g)

type Lens s t a b = forall f. Functor f => LensLike f s t a b

type Setting' (p :: Type -> Type -> Type) s a = Setting p s s a a #

This is a convenient alias when defining highly polymorphic code that takes both ASetter' and AnIndexedSetter' as appropriate. If a function takes this it is expecting one of those two things based on context.

type Setting (p :: Type -> Type -> Type) s t a b = p a (Identity b) -> s -> Identity t #

This is a convenient alias when defining highly polymorphic code that takes both ASetter and AnIndexedSetter as appropriate. If a function takes this it is expecting one of those two things based on context.

type AnIndexedSetter' i s a = AnIndexedSetter i s s a a #

type AnIndexedSetter' i = Simple (AnIndexedSetter i)

type AnIndexedSetter i s t a b = Indexed i a (Identity b) -> s -> Identity t #

Running an IndexedSetter instantiates it to a concrete type.

When consuming a setter directly to perform a mapping, you can use this type, but most user code will not need to use this type.

type ASetter' s a = ASetter s s a a #

This is a useful alias for use when consuming a Setter'.

Most user code will never have to use this type.

type ASetter' = Simple ASetter

type ASetter s t a b = (a -> Identity b) -> s -> Identity t #

Running a Setter instantiates it to a concrete type.

When consuming a setter directly to perform a mapping, you can use this type, but most user code will not need to use this type.

mapped :: Functor f => Setter (f a) (f b) a b #

This Setter can be used to map over all of the values in a Functor.

fmap ≡ over mapped
fmapDefault ≡ over traverse
(<$) ≡ set mapped

>>> over mapped f [a,b,c]
[f a,f b,f c]

>>> over mapped (+1) [1,2,3]
[2,3,4]

>>> set mapped x [a,b,c]
[x,x,x]

>>> [[a,b],[c]] & mapped.mapped +~ x
[[a + x,b + x],[c + x]]

>>> over (mapped._2) length [("hello","world"),("leaders","!!!")]
[("hello",5),("leaders",3)]

mapped :: Functor f => Setter (f a) (f b) a b

If you want an IndexPreservingSetter use setting fmap.

lifted :: Monad m => Setter (m a) (m b) a b #

This setter can be used to modify all of the values in a Monad.

You sometimes have to use this rather than mapped -- due to temporary insanity Functor was not a superclass of Monad until GHC 7.10.

liftM ≡ over lifted

>>> over lifted f [a,b,c]
[f a,f b,f c]

>>> set lifted b (Just a)
Just b

If you want an IndexPreservingSetter use setting liftM.

contramapped :: Contravariant f => Setter (f b) (f a) a b #

This Setter can be used to map over all of the inputs to a Contravariant.

contramap ≡ over contramapped

>>> getPredicate (over contramapped (*2) (Predicate even)) 5
True

>>> getOp (over contramapped (*5) (Op show)) 100
"500"

>>> Prelude.map ($ 1) $ over (mapped . _Unwrapping' Op . contramapped) (*12) [(*2),(+1),(^3)]
[24,13,1728]

setting :: ((a -> b) -> s -> t) -> IndexPreservingSetter s t a b #

Build an index-preserving Setter from a map-like function.

Your supplied function f is required to satisfy:

f id ≡ id
f g . f h ≡ f (g . h)

Equational reasoning:

setting . over ≡ id
over . setting ≡ id

Another way to view sets is that it takes a "semantic editor combinator" and transforms it into a Setter.

setting :: ((a -> b) -> s -> t) -> Setter s t a b

sets :: (Profunctor p, Profunctor q, Settable f) => (p a b -> q s t) -> Optical p q f s t a b #

Build a Setter, IndexedSetter or IndexPreservingSetter depending on your choice of Profunctor.

sets :: ((a -> b) -> s -> t) -> Setter s t a b

cloneSetter :: ASetter s t a b -> Setter s t a b #

Restore ASetter to a full Setter.

cloneIndexPreservingSetter :: ASetter s t a b -> IndexPreservingSetter s t a b #

Build an IndexPreservingSetter from any Setter.

cloneIndexedSetter :: AnIndexedSetter i s t a b -> IndexedSetter i s t a b #

Clone an IndexedSetter.

over :: ASetter s t a b -> (a -> b) -> s -> t #

Modify the target of a Lens or all the targets of a Setter or Traversal with a function.

fmap ≡ over mapped
fmapDefault ≡ over traverse
sets . over ≡ id
over . sets ≡ id

Given any valid Setter l, you can also rely on the law:

over l f . over l g = over l (f . g)

e.g.

>>> over mapped f (over mapped g [a,b,c]) == over mapped (f . g) [a,b,c]
True

Another way to view over is to say that it transforms a Setter into a "semantic editor combinator".

>>> over mapped f (Just a)
Just (f a)

>>> over mapped (*10) [1,2,3]
[10,20,30]

>>> over _1 f (a,b)
(f a,b)

>>> over _1 show (10,20)
("10",20)

over :: Setter s t a b -> (a -> b) -> s -> t
over :: ASetter s t a b -> (a -> b) -> s -> t

set :: ASetter s t a b -> b -> s -> t #

Replace the target of a Lens or all of the targets of a Setter or Traversal with a constant value.

(<$) ≡ set mapped

>>> set _2 "hello" (1,())
(1,"hello")

>>> set mapped () [1,2,3,4]
[(),(),(),()]

Note: Attempting to set a Fold or Getter will fail at compile time with an relatively nice error message.

set :: Setter s t a b    -> b -> s -> t
set :: Iso s t a b       -> b -> s -> t
set :: Lens s t a b      -> b -> s -> t
set :: Traversal s t a b -> b -> s -> t

set' :: ASetter' s a -> a -> s -> s #

Replace the target of a Lens or all of the targets of a Setter' or Traversal with a constant value, without changing its type.

This is a type restricted version of set, which retains the type of the original.

>>> set' mapped x [a,b,c,d]
[x,x,x,x]

>>> set' _2 "hello" (1,"world")
(1,"hello")

>>> set' mapped 0 [1,2,3,4]
[0,0,0,0]

Note: Attempting to adjust set' a Fold or Getter will fail at compile time with an relatively nice error message.

This is an infix version of over.

fmap f ≡ mapped %~ f

Replace the target of a Lens or all of the targets of a Setter or Traversal with a constant value.

This is an infix version of set, provided for consistency with (.=).

f <$ a ≡ mapped .~ f $ a

When you do not need access to the index then (%=) is more liberal in what it can accept.

l %= f ≡ l %@= const f

(%@=) :: MonadState s m => IndexedSetter i s s a b    -> (i -> a -> b) -> m ()
(%@=) :: MonadState s m => IndexedLens i s s a b      -> (i -> a -> b) -> m ()
(%@=) :: MonadState s m => IndexedTraversal i s t a b -> (i -> a -> b) -> m ()

imodifying :: MonadState s m => AnIndexedSetter i s s a b -> (i -> a -> b) -> m () #

This is an alias for (%@=).

(.@=) :: MonadState s m => AnIndexedSetter i s s a b -> (i -> b) -> m () infix 4 #

Replace every target in the current state of an IndexedSetter, IndexedLens or IndexedTraversal with access to the index.

When you do not need access to the index then (.=) is more liberal in what it can accept.

(.@=) :: MonadState s m => IndexedTraversal i s t a b -> (i -> b) -> m ()

assignA :: Arrow p => ASetter s t a b -> p s b -> p s t #

Run an arrow command and use the output to set all the targets of a Lens, Setter or Traversal to the result.

assignA can be used very similarly to (<~), except that the type of the object being modified can change; for example:

runKleisli action ((), (), ()) where
  action =      assignA _1 (Kleisli (const getVal1))
           >>> assignA _2 (Kleisli (const getVal2))
           >>> assignA _3 (Kleisli (const getVal3))
  getVal1 :: Either String Int
  getVal1 = ...
  getVal2 :: Either String Bool
  getVal2 = ...
  getVal3 :: Either String Char
  getVal3 = ...

has the type Either String (Int, Bool, Char)

assignA :: Arrow p => Iso s t a b       -> p s b -> p s t
assignA :: Arrow p => Lens s t a b      -> p s b -> p s t
assignA :: Arrow p => Traversal s t a b -> p s b -> p s t
assignA :: Arrow p => Setter s t a b    -> p s b -> p s t

mapOf :: ASetter s t a b -> (a -> b) -> s -> t #

mapOf is a deprecated alias for over.

imapOf :: AnIndexedSetter i s t a b -> (i -> a -> b) -> s -> t #

Map with index. (Deprecated alias for iover).

When you do not need access to the index, then mapOf is more liberal in what it can accept.

mapOf l ≡ imapOf l . const

imapOf :: IndexedSetter i s t a b    -> (i -> a -> b) -> s -> t
imapOf :: IndexedLens i s t a b      -> (i -> a -> b) -> s -> t
imapOf :: IndexedTraversal i s t a b -> (i -> a -> b) -> s -> t

type AnIndexedLens' i s a = AnIndexedLens i s s a a #

type AnIndexedLens' = Simple (AnIndexedLens i)

type AnIndexedLens i s t a b = Optical (Indexed i) ((->) :: Type -> Type -> Type) (Pretext (Indexed i) a b) s t a b #

When you see this as an argument to a function, it expects an IndexedLens

type ALens' s a = ALens s s a a #

type ALens' = Simple ALens

type ALens s t a b = LensLike (Pretext ((->) :: Type -> Type -> Type) a b) s t a b #

When you see this as an argument to a function, it expects a Lens.

This type can also be used when you need to store a Lens in a container, since it is rank-1. You can turn them back into a Lens with cloneLens, or use it directly with combinators like storing and (^#).

lens :: (s -> a) -> (s -> b -> t) -> Lens s t a b #

Build a Lens from a getter and a setter.

lens :: Functor f => (s -> a) -> (s -> b -> t) -> (a -> f b) -> s -> f t

>>> s ^. lens getter setter
getter s

>>> s & lens getter setter .~ b
setter s b

>>> s & lens getter setter %~ f
setter s (f (getter s))

lens :: (s -> a) -> (s -> a -> s) -> Lens' s a

iplens :: (s -> a) -> (s -> b -> t) -> IndexPreservingLens s t a b #

Build an index-preserving Lens from a Getter and a Setter.

ilens :: (s -> (i, a)) -> (s -> b -> t) -> IndexedLens i s t a b #

Build an IndexedLens from a Getter and a Setter.

(&~) :: s -> State s a -> s infixl 1 #

This can be used to chain lens operations using op= syntax rather than op~ syntax for simple non-type-changing cases.

>>> (10,20) & _1 .~ 30 & _2 .~ 40
(30,40)

>>> (10,20) &~ do _1 .= 30; _2 .= 40
(30,40)

This does not support type-changing assignment, e.g.

>>> (10,20) & _1 .~ "hello"
("hello",20)

(%%~) :: LensLike f s t a b -> (a -> f b) -> s -> f t infixr 4 #

(%%~) can be used in one of two scenarios:

When applied to a Lens, it can edit the target of the Lens in a structure, extracting a functorial result.

When applied to a Traversal, it can edit the targets of the traversals, extracting an applicative summary of its actions.

>>> [66,97,116,109,97,110] & each %%~ \a -> ("na", chr a)
("nananananana","Batman")

For all that the definition of this combinator is just:

(%%~) ≡ id

It may be beneficial to think about it as if it had these even more restricted types, however:

(%%~) :: Functor f =>     Iso s t a b       -> (a -> f b) -> s -> f t
(%%~) :: Functor f =>     Lens s t a b      -> (a -> f b) -> s -> f t
(%%~) :: Applicative f => Traversal s t a b -> (a -> f b) -> s -> f t

When applied to a Traversal, it can edit the targets of the traversals, extracting a supplemental monoidal summary of its actions, by choosing f = ((,) m)

(%%~) ::             Iso s t a b       -> (a -> (r, b)) -> s -> (r, t)
(%%~) ::             Lens s t a b      -> (a -> (r, b)) -> s -> (r, t)
(%%~) :: Monoid m => Traversal s t a b -> (a -> (m, b)) -> s -> (m, t)

(%%=) :: MonadState s m => Over p ((,) r) s s a b -> p a (r, b) -> m r infix 4 #

Modify the target of a Lens in the current state returning some extra information of type r or modify all targets of a Traversal in the current state, extracting extra information of type r and return a monoidal summary of the changes.

>>> runState (_1 %%= \x -> (f x, g x)) (a,b)
(f a,(g a,b))

(%%=) ≡ (state .)

It may be useful to think of (%%=), instead, as having either of the following more restricted type signatures:

(%%=) :: MonadState s m             => Iso s s a b       -> (a -> (r, b)) -> m r
(%%=) :: MonadState s m             => Lens s s a b      -> (a -> (r, b)) -> m r
(%%=) :: (MonadState s m, Monoid r) => Traversal s s a b -> (a -> (r, b)) -> m r

(??) :: Functor f => f (a -> b) -> a -> f b infixl 1 #

This is convenient to flip argument order of composite functions defined as:

fab ?? a = fmap ($ a) fab

For the Functor instance f = ((->) r) you can reason about this function as if the definition was (??) ≡ flip:

>>> (h ?? x) a
h a x

>>> execState ?? [] $ modify (1:)
[1]

>>> over _2 ?? ("hello","world") $ length
("hello",5)

>>> over ?? length ?? ("hello","world") $ _2
("hello",5)

choosing :: Functor f => LensLike f s t a b -> LensLike f s' t' a b -> LensLike f (Either s s') (Either t t') a b #

Merge two lenses, getters, setters, folds or traversals.

chosen ≡ choosing id id

choosing :: Getter s a     -> Getter s' a     -> Getter (Either s s') a
choosing :: Fold s a       -> Fold s' a       -> Fold (Either s s') a
choosing :: Lens' s a      -> Lens' s' a      -> Lens' (Either s s') a
choosing :: Traversal' s a -> Traversal' s' a -> Traversal' (Either s s') a
choosing :: Setter' s a    -> Setter' s' a    -> Setter' (Either s s') a

chosen :: IndexPreservingLens (Either a a) (Either b b) a b #

This is a Lens that updates either side of an Either, where both sides have the same type.

chosen ≡ choosing id id

>>> Left a^.chosen
a

>>> Right a^.chosen
a

>>> Right "hello"^.chosen
"hello"

>>> Right a & chosen *~ b
Right (a * b)

chosen :: Lens (Either a a) (Either b b) a b
chosen f (Left a)  = Left <$> f a
chosen f (Right a) = Right <$> f a

alongside :: LensLike (AlongsideLeft f b') s t a b -> LensLike (AlongsideRight f t) s' t' a' b' -> LensLike f (s, s') (t, t') (a, a') (b, b') #

alongside makes a Lens from two other lenses or a Getter from two other getters by executing them on their respective halves of a product.

>>> (Left a, Right b)^.alongside chosen chosen
(a,b)

>>> (Left a, Right b) & alongside chosen chosen .~ (c,d)
(Left c,Right d)

alongside :: Lens   s t a b -> Lens   s' t' a' b' -> Lens   (s,s') (t,t') (a,a') (b,b')
alongside :: Getter s   a   -> Getter s'    a'    -> Getter (s,s')        (a,a')

locus :: IndexedComonadStore p => Lens (p a c s) (p b c s) a b #

This Lens lets you view the current pos of any indexed store comonad and seek to a new position. This reduces the API for working these instances to a single Lens.

ipos w ≡ w ^. locus
iseek s w ≡ w & locus .~ s
iseeks f w ≡ w & locus %~ f

locus :: Lens' (Context' a s) a
locus :: Conjoined p => Lens' (Pretext' p a s) a
locus :: Conjoined p => Lens' (PretextT' p g a s) a

cloneLens :: ALens s t a b -> Lens s t a b #

Cloning a Lens is one way to make sure you aren't given something weaker, such as a Traversal and can be used as a way to pass around lenses that have to be monomorphic in f.

Note: This only accepts a proper Lens.

>>> let example l x = set (cloneLens l) (x^.cloneLens l + 1) x in example _2 ("hello",1,"you")
("hello",2,"you")

cloneIndexPreservingLens :: ALens s t a b -> IndexPreservingLens s t a b #

Clone a Lens as an IndexedPreservingLens that just passes through whatever index is on any IndexedLens, IndexedFold, IndexedGetter or IndexedTraversal it is composed with.

cloneIndexedLens :: AnIndexedLens i s t a b -> IndexedLens i s t a b #

fusing :: Functor f => LensLike (Yoneda f) s t a b -> LensLike f s t a b #

Fuse a composition of lenses using Yoneda to provide fmap fusion.

In general, given a pair of lenses foo and bar

fusing (foo.bar) = foo.bar

however, foo and bar are either going to fmap internally or they are trivial.

fusing exploits the Yoneda lemma to merge these separate uses into a single fmap.

This is particularly effective when the choice of functor f is unknown at compile time or when the Lens foo.bar in the above description is recursive or complex enough to prevent inlining.

type Accessing (p :: Type -> Type -> Type) m s a = p a (Const m a) -> s -> Const m s #

This is a convenient alias used when consuming (indexed) getters and (indexed) folds in a highly general fashion.

type IndexedGetting i m s a = Indexed i a (Const m a) -> s -> Const m s #

Used to consume an IndexedFold.

type Getting r s a = (a -> Const r a) -> s -> Const r s #

When you see this in a type signature it indicates that you can pass the function a Lens, Getter, Traversal, Fold, Prism, Iso, or one of the indexed variants, and it will just "do the right thing".

Most Getter combinators are able to be used with both a Getter or a Fold in limited situations, to do so, they need to be monomorphic in what we are going to extract with Const. To be compatible with Lens, Traversal and Iso we also restricted choices of the irrelevant t and b parameters.

If a function accepts a Getting r s a, then when r is a Monoid, then you can pass a Fold (or Traversal), otherwise you can only pass this a Getter or Lens.

to :: (Profunctor p, Contravariant f) => (s -> a) -> Optic' p f s a #

Build an (index-preserving) Getter from an arbitrary Haskell function.

to f . to g ≡ to (g . f)

a ^. to f ≡ f a

>>> a ^.to f
f a

>>> ("hello","world")^.to snd
"world"

>>> 5^.to succ
6

>>> (0, -5)^._2.to abs
5

to :: (s -> a) -> IndexPreservingGetter s a

ito :: (Indexable i p, Contravariant f) => (s -> (i, a)) -> Over' p f s a #

ito :: (s -> (i, a)) -> IndexedGetter i s a

like :: (Profunctor p, Contravariant f, Functor f) => a -> Optic' p f s a #

Build an constant-valued (index-preserving) Getter from an arbitrary Haskell value.

like a . like b ≡ like b
a ^. like b ≡ b
a ^. like b ≡ a ^. to (const b)

This can be useful as a second case failing a Fold e.g. foo failing like 0

like :: a -> IndexPreservingGetter s a

ilike :: (Indexable i p, Contravariant f, Functor f) => i -> a -> Over' p f s a #

ilike :: i -> a -> IndexedGetter i s a

view :: MonadReader s m => Getting a s a -> m a #

View the value pointed to by a Getter, Iso or Lens or the result of folding over all the results of a Fold or Traversal that points at a monoidal value.

view . to ≡ id

>>> view (to f) a
f a

>>> view _2 (1,"hello")
"hello"

>>> view (to succ) 5
6

>>> view (_2._1) ("hello",("world","!!!"))
"world"

As view is commonly used to access the target of a Getter or obtain a monoidal summary of the targets of a Fold, It may be useful to think of it as having one of these more restricted signatures:

view ::             Getter s a     -> s -> a
view :: Monoid m => Fold s m       -> s -> m
view ::             Iso' s a       -> s -> a
view ::             Lens' s a      -> s -> a
view :: Monoid m => Traversal' s m -> s -> m

In a more general setting, such as when working with a Monad transformer stack you can use:

view :: MonadReader s m             => Getter s a     -> m a
view :: (MonadReader s m, Monoid a) => Fold s a       -> m a
view :: MonadReader s m             => Iso' s a       -> m a
view :: MonadReader s m             => Lens' s a      -> m a
view :: (MonadReader s m, Monoid a) => Traversal' s a -> m a

views :: MonadReader s m => LensLike' (Const r :: Type -> Type) s a -> (a -> r) -> m r #

View a function of the value pointed to by a Getter or Lens or the result of folding over the result of mapping the targets of a Fold or Traversal.

views l f ≡ view (l . to f)

>>> views (to f) g a
g (f a)

>>> views _2 length (1,"hello")
5

As views is commonly used to access the target of a Getter or obtain a monoidal summary of the targets of a Fold, It may be useful to think of it as having one of these more restricted signatures:

views ::             Getter s a     -> (a -> r) -> s -> r
views :: Monoid m => Fold s a       -> (a -> m) -> s -> m
views ::             Iso' s a       -> (a -> r) -> s -> r
views ::             Lens' s a      -> (a -> r) -> s -> r
views :: Monoid m => Traversal' s a -> (a -> m) -> s -> m

In a more general setting, such as when working with a Monad transformer stack you can use:

views :: MonadReader s m             => Getter s a     -> (a -> r) -> m r
views :: (MonadReader s m, Monoid r) => Fold s a       -> (a -> r) -> m r
views :: MonadReader s m             => Iso' s a       -> (a -> r) -> m r
views :: MonadReader s m             => Lens' s a      -> (a -> r) -> m r
views :: (MonadReader s m, Monoid r) => Traversal' s a -> (a -> r) -> m r

views :: MonadReader s m => Getting r s a -> (a -> r) -> m r

(^.) :: s -> Getting a s a -> a infixl 8 #

View the value pointed to by a Getter or Lens or the result of folding over all the results of a Fold or Traversal that points at a monoidal values.

This is the same operation as view with the arguments flipped.

The fixity and semantics are such that subsequent field accesses can be performed with (.).

type APrism' s a = APrism s s a a #

type APrism' = Simple APrism

type APrism s t a b = Market a b a (Identity b) -> Market a b s (Identity t) #

If you see this in a signature for a function, the function is expecting a Prism.

withPrism :: APrism s t a b -> ((b -> t) -> (s -> Either t a) -> r) -> r #

Convert APrism to the pair of functions that characterize it.

clonePrism :: APrism s t a b -> Prism s t a b #

Clone a Prism so that you can reuse the same monomorphically typed Prism for different purposes.

See cloneLens and cloneTraversal for examples of why you might want to do this.

prism :: (b -> t) -> (s -> Either t a) -> Prism s t a b #

Build a Prism.

Either t a is used instead of Maybe a to permit the types of s and t to differ.

prism' :: (b -> s) -> (s -> Maybe a) -> Prism s s a b #

This is usually used to build a Prism', when you have to use an operation like cast which already returns a Maybe.

without :: APrism s t a b -> APrism u v c d -> Prism (Either s u) (Either t v) (Either a c) (Either b d) #

Given a pair of prisms, project sums.

Viewing a Prism as a co-Lens, this combinator can be seen to be dual to alongside.

aside :: APrism s t a b -> Prism (e, s) (e, t) (e, a) (e, b) #

Use a Prism to work over part of a structure.

below :: Traversable f => APrism' s a -> Prism' (f s) (f a) #

lift a Prism through a Traversable functor, giving a Prism that matches only if all the elements of the container match the Prism.

>>> [Left 1, Right "foo", Left 4, Right "woot"]^..below _Right
[]

>>> [Right "hail hydra!", Right "foo", Right "blah", Right "woot"]^..below _Right
[["hail hydra!","foo","blah","woot"]]

isn't :: APrism s t a b -> s -> Bool #

Check to see if this Prism doesn't match.

>>> isn't _Left (Right 12)
True

>>> isn't _Left (Left 12)
False

>>> isn't _Empty []
False

matching :: APrism s t a b -> s -> Either t a #

Retrieve the value targeted by a Prism or return the original value while allowing the type to change if it does not match.

>>> matching _Just (Just 12)
Right 12

>>> matching _Just (Nothing :: Maybe Int) :: Either (Maybe Bool) Int
Left Nothing

_Left :: Prism (Either a c) (Either b c) a b #

This Prism provides a Traversal for tweaking the Left half of an Either:

>>> over _Left (+1) (Left 2)
Left 3

>>> over _Left (+1) (Right 2)
Right 2

>>> Right 42 ^._Left :: String
""

>>> Left "hello" ^._Left
"hello"

It also can be turned around to obtain the embedding into the Left half of an Either:

>>> _Left # 5
Left 5

>>> 5^.re _Left
Left 5

_Right :: Prism (Either c a) (Either c b) a b #

This Prism provides a Traversal for tweaking the Right half of an Either:

>>> over _Right (+1) (Left 2)
Left 2

>>> over _Right (+1) (Right 2)
Right 3

>>> Right "hello" ^._Right
"hello"

>>> Left "hello" ^._Right :: [Double]
[]

It also can be turned around to obtain the embedding into the Right half of an Either:

>>> _Right # 5
Right 5

>>> 5^.re _Right
Right 5

_Just :: Prism (Maybe a) (Maybe b) a b #

This Prism provides a Traversal for tweaking the target of the value of Just in a Maybe.

>>> over _Just (+1) (Just 2)
Just 3

Unlike traverse this is a Prism, and so you can use it to inject as well:

>>> _Just # 5
Just 5

>>> 5^.re _Just
Just 5

Interestingly,

m ^? _Just ≡ m

>>> Just x ^? _Just
Just x

>>> Nothing ^? _Just
Nothing

_Nothing :: Prism' (Maybe a) () #

This Prism provides the Traversal of a Nothing in a Maybe.

>>> Nothing ^? _Nothing
Just ()

>>> Just () ^? _Nothing
Nothing

But you can turn it around and use it to construct Nothing as well:

>>> _Nothing # ()
Nothing

_Void :: Prism s s a Void #

Void is a logically uninhabited data type.

This is a Prism that will always fail to match.

only :: Eq a => a -> Prism' a () #

This Prism compares for exact equality with a given value.

>>> only 4 # ()
4

>>> 5 ^? only 4
Nothing

nearly :: a -> (a -> Bool) -> Prism' a () #

This Prism compares for approximate equality with a given value and a predicate for testing, an example where the value is the empty list and the predicate checks that a list is empty (same as _Empty with the AsEmpty list instance):

>>> nearly [] null # ()
[]
>>> [1,2,3,4] ^? nearly [] null
Nothing

nearly [] null :: Prism' [a] ()

To comply with the Prism laws the arguments you supply to nearly a p are somewhat constrained.

We assume p x holds iff x ≡ a. Under that assumption then this is a valid Prism.

This is useful when working with a type where you can test equality for only a subset of its values, and the prism selects such a value.

_Show :: (Read a, Show a) => Prism' String a #

This is an improper prism for text formatting based on Read and Show.

This Prism is "improper" in the sense that it normalizes the text formatting, but round tripping is idempotent given sane 'Read'/'Show' instances.

>>> _Show # 2
"2"

>>> "EQ" ^? _Show :: Maybe Ordering
Just EQ

_Show ≡ prism' show readMaybe

folding :: Foldable f => (s -> f a) -> Fold s a #

Obtain a Fold by lifting an operation that returns a Foldable result.

This can be useful to lift operations from Data.List and elsewhere into a Fold.

[2,3,4]

ifolding :: (Foldable f, Indexable i p, Contravariant g, Applicative g) => (s -> f (i, a)) -> Over p g s t a b #

foldring :: (Contravariant f, Applicative f) => ((a -> f a -> f a) -> f a -> s -> f a) -> LensLike f s t a b #

Transform a non-empty Fold into a Fold1 that loops over its elements over and over.

>>> timingOut $ [1,2,3]^..taking 7 (cycled traverse)
[1,2,3,1,2,3,1]

cycled :: Fold1 s a -> Fold1 s a

unfolded :: (b -> Maybe (a, b)) -> Fold b a #

Build a Fold that unfolds its values from a seed.

unfoldr ≡ toListOf . unfolded

[10,9,8,7,6,5,4,3,2,1]

iterated :: Apply f => (a -> a) -> LensLike' f a a #

toListOf (iterated f) a ≡ iterate f a

iterated :: (a -> a) -> Fold1 a a

filtered :: (Choice p, Applicative f) => (a -> Bool) -> Optic' p f a a #

Obtain a Fold that can be composed with to filter another Lens, Iso, Getter, Fold (or Traversal).

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

Note: This is also not a legal Prism, unless you are very careful not to inject a value that matches the predicate.

As a counter example, consider that given evens = filtered 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!

>>> [1..10]^..folded.filtered even
[2,4,6,8,10]

This will preserve an index if it is present.

takingWhile :: (Conjoined p, Applicative f) => (a -> Bool) -> Over p (TakingWhile p f a a) s t a a -> Over p f s t a a #

Obtain a Fold by taking elements from another Fold, Lens, Iso, Getter or Traversal while a predicate holds.

takeWhile p ≡ toListOf (takingWhile p folded)

>>> timingOut $ toListOf (takingWhile (<=3) folded) [1..]
[1,2,3]

takingWhile :: (a -> Bool) -> Fold s a                         -> Fold s a
takingWhile :: (a -> Bool) -> Getter s a                       -> Fold s a

takingWhile :: (a -> Bool) -> IndexedFold i s a                -> IndexedFold i s a
takingWhile :: (a -> Bool) -> IndexedGetter i s a              -> IndexedFold i s a

Note: When applied to a Traversal, takingWhile yields something that can be used as if it were a Traversal, but which is not a Traversal per the laws, unless you are careful to ensure that you do not invalidate the predicate when writing back through it.

droppingWhile :: (Conjoined p, Profunctor q, Applicative f) => (a -> Bool) -> Optical p q (Compose (State Bool) f) s t a a -> Optical p q f s t a a #

Obtain a Fold by dropping elements from another Fold, Lens, Iso, Getter or Traversal while a predicate holds.

droppingWhile :: (a -> Bool) -> IndexPreservingFold s a          -> IndexPreservingFold s a

droppingWhile :: (a -> Bool) -> IndexedTraversal' i s a          -> IndexedFold i s a       -- see notes
droppingWhile :: (a -> Bool) -> IndexedLens' i s a               -> IndexedFold i s a       -- see notes
droppingWhile :: (a -> Bool) -> IndexedGetter i s a              -> IndexedFold i s a
droppingWhile :: (a -> Bool) -> IndexedFold i s a                -> IndexedFold i s a

Note: Many uses of this combinator will yield something that meets the types, but not the laws of a valid Traversal or IndexedTraversal. The Traversal and IndexedTraversal laws are only satisfied if the new values you assign to the first target also does not pass the predicate! Otherwise subsequent traversals will visit fewer elements and Traversal fusion is not sound.

So for any traversal t and predicate p, droppingWhile p t may not be lawful, but (dropping 1 . droppingWhile p) t is. For example:

>>> let l  :: Traversal' [Int] Int; l  = droppingWhile (<= 1) traverse
>>> let l' :: Traversal' [Int] Int; l' = dropping 1 l

l is not a lawful setter because over l f . over l g ≢ over l (f . g):

>>> [1,2,3] & l .~ 0 & l .~ 4
[1,0,0]
>>> [1,2,3] & l .~ 4
[1,4,4]

l' on the other hand behaves lawfully:

>>> [1,2,3] & l' .~ 0 & l' .~ 4
[1,2,4]
>>> [1,2,3] & l' .~ 4
[1,2,4]

worded :: Applicative f => IndexedLensLike' Int f String String #

A Fold over the individual words of a String.

worded :: Fold String String

Note: This function type-checks as a Traversal but it doesn't satisfy the laws. It's only valid to use it when you don't insert any whitespace characters while traversing, and if your original String contains only isolated space characters (and no other characters that count as space, such as non-breaking spaces).

traverseOf_ :: Functor f     => Getter s a     -> (a -> f r) -> s -> f ()
traverseOf_ :: Applicative f => Fold s a       -> (a -> f r) -> s -> f ()
traverseOf_ :: Functor f     => Lens' s a      -> (a -> f r) -> s -> f ()
traverseOf_ :: Functor f     => Iso' s a       -> (a -> f r) -> s -> f ()
traverseOf_ :: Applicative f => Traversal' s a -> (a -> f r) -> s -> f ()
traverseOf_ :: Applicative f => Prism' s a     -> (a -> f r) -> s -> f ()

forOf_ :: Functor f => Getting (Traversed r f) s a -> s -> (a -> f r) -> f () #

Traverse over all of the targets of a Fold (or Getter), computing an Applicative (or Functor)-based answer, but unlike forOf do not construct a new structure. forOf_ generalizes for_ to work over any Fold.

When passed a Getter, forOf_ can work over any Functor, but when passed a Fold, forOf_ requires an Applicative.

itoListOf :: IndexedGetting i (Endo [(i, a)]) s a -> s -> [(i, a)] #

Perform a safe head (with index) of an IndexedFold or IndexedTraversal or retrieve Just the index and result from an IndexedGetter or IndexedLens.

When using a IndexedTraversal as a partial IndexedLens, or an IndexedFold as a partial IndexedGetter this can be a convenient way to extract the optional value.

Filter an IndexedFold or IndexedGetter, obtaining an IndexedFold.

>>> [0,0,0,5,5,5]^..traversed.ifiltered (\i a -> i <= a)
[0,5,5,5]

Compose with ifiltered to filter another IndexedLens, IndexedIso, IndexedGetter, IndexedFold (or IndexedTraversal) with access to both the value and the index.

Note: As with filtered, this is not a legal IndexedTraversal, unless you are very careful not to invalidate the predicate on the target!

itakingWhile :: (Indexable i p, Profunctor q, Contravariant f, Applicative f) => (i -> a -> Bool) -> Optical' (Indexed i) q (Const (Endo (f s)) :: Type -> Type) s a -> Optical' p q f s a #

itakingWhile :: (i -> a -> Bool) -> IndexedGetter i s a        -> IndexedFold i s a

Note: Applying itakingWhile to an IndexedLens or IndexedTraversal will still allow you to use it as a pseudo-IndexedTraversal, but if you change the value of any target to one where the predicate returns False, then you will break the Traversal laws and Traversal fusion will no longer be sound.

idroppingWhile :: (Indexable i p, Profunctor q, Applicative f) => (i -> a -> Bool) -> Optical (Indexed i) q (Compose (State Bool) f) s t a a -> Optical p q f s t a a #

Obtain an IndexedFold by dropping elements from another IndexedFold, IndexedLens, IndexedGetter or IndexedTraversal while a predicate holds.

idroppingWhile :: (i -> a -> Bool) -> IndexedGetter i s a        -> IndexedFold i s a

Note: As with droppingWhile applying idroppingWhile to an IndexedLens or IndexedTraversal will still allow you to use it as a pseudo-IndexedTraversal, but if you change the value of the first target to one where the predicate returns True, then you will break the Traversal laws and Traversal fusion will no longer be sound.

Note: transpose handles ragged inputs more intelligently, but for non-ragged inputs:

>>> transposeOf traverse [[1,2,3],[4,5,6]]
[[1,4],[2,5],[3,6]]

transpose ≡ transposeOf traverse

Since every Lens is a Traversal, we can use this as a form of monadic strength as well:

transposeOf _2 :: (b, [a]) -> [(b, a)]

mapAccumROf :: LensLike (Backwards (State acc)) s t a b -> (acc -> a -> (acc, b)) -> acc -> s -> (acc, t) #

This generalizes mapAccumR to an arbitrary Traversal.

mapAccumROf accumulates State from right to left.

mapAccumROf :: Iso s t a b       -> (acc -> a -> (acc, b)) -> acc -> s -> (acc, t)
mapAccumROf :: Lens s t a b      -> (acc -> a -> (acc, b)) -> acc -> s -> (acc, t)

mapAccumROf :: LensLike (Backwards (State acc)) s t a b -> (acc -> a -> (acc, b)) -> acc -> s -> (acc, t)

mapAccumLOf :: LensLike (State acc) s t a b -> (acc -> a -> (acc, b)) -> acc -> s -> (acc, t) #

This generalizes mapAccumL to an arbitrary Traversal.

mapAccumL ≡ mapAccumLOf traverse

mapAccumLOf accumulates State from left to right.

mapAccumLOf :: Iso s t a b       -> (acc -> a -> (acc, b)) -> acc -> s -> (acc, t)

scanr1Of :: LensLike (Backwards (State (Maybe a))) s t a a -> (a -> a -> a) -> s -> t #

This permits the use of scanr1 over an arbitrary Traversal or Lens.

scanr1 ≡ scanr1Of traverse

scanr1Of :: Iso s t a a       -> (a -> a -> a) -> s -> t
scanr1Of :: Lens s t a a      -> (a -> a -> a) -> s -> t
scanr1Of :: Traversal s t a a -> (a -> a -> a) -> s -> t

scanl1Of :: LensLike (State (Maybe a)) s t a a -> (a -> a -> a) -> s -> t #

loci :: Traversal (Bazaar ((->) :: Type -> Type -> Type) a c s) (Bazaar ((->) :: Type -> Type -> Type) b c s) a b #

This Traversal allows you to traverse the individual stores in a Bazaar.

iloci :: IndexedTraversal i (Bazaar (Indexed i) a c s) (Bazaar (Indexed i) b c s) a b #

This IndexedTraversal allows you to traverse the individual stores in a Bazaar with access to their indices.

partsOf :: Functor f => Traversing ((->) :: Type -> Type -> Type) f s t a a -> LensLike f s t [a] [a] #

partsOf turns a Traversal into a Lens that resembles an early version of the uniplate (or biplate) type.

Note: You should really try to maintain the invariant of the number of children in the list.

>>> (a,b,c) & partsOf each .~ [x,y,z]
(x,y,z)

Any extras will be lost. If you do not supply enough, then the remainder will come from the original structure.

>>> (a,b,c) & partsOf each .~ [w,x,y,z]
(w,x,y)

>>> (a,b,c) & partsOf each .~ [x,y]
(x,y,c)

>>> ('b', 'a', 'd', 'c') & partsOf each %~ sort
('a','b','c','d')

So technically, this is only a Lens if you do not change the number of results it returns.

When applied to a Fold the result is merely a Getter.

partsOf :: Lens' s a      -> Lens' s [a]

partsOf :: Getter s a     -> Getter s [a]

ipartsOf :: (Indexable [i] p, Functor f) => Traversing (Indexed i) f s t a a -> Over p f s t [a] [a] #

An indexed version of partsOf that receives the entire list of indices as its index.

partsOf' :: ATraversal s t a a -> Lens s t [a] [a] #

A type-restricted version of partsOf that can only be used with a Traversal.

ipartsOf' :: (Indexable [i] p, Functor f) => Over (Indexed i) (Bazaar' (Indexed i) a) s t a a -> Over p f s t [a] [a] #

A type-restricted version of ipartsOf that can only be used with an IndexedTraversal.

unsafePartsOf :: Functor f => Traversing ((->) :: Type -> Type -> Type) f s t a b -> LensLike f s t [a] [b] #

unsafePartsOf turns a Traversal into a uniplate (or biplate) family.

If you do not need the types of s and t to be different, it is recommended that you use partsOf.

It is generally safer to traverse with the Bazaar rather than use this combinator. However, it is sometimes convenient.

This is unsafe because if you don't supply at least as many b's as you were given a's, then the reconstruction of t will result in an error!

When applied to a Fold the result is merely a Getter (and becomes safe).

unsafePartsOf :: Iso s t a b       -> Lens s t [a] [b]
unsafePartsOf :: Lens s t a b      -> Lens s t [a] [b]

iunsafePartsOf :: (Indexable [i] p, Functor f) => Traversing (Indexed i) f s t a b -> Over p f s t [a] [b] #

An indexed version of unsafePartsOf that receives the entire list of indices as its index.

iunsafePartsOf' :: Over (Indexed i) (Bazaar (Indexed i) a b) s t a b -> IndexedLens [i] s t [a] [b] #

unsafeSingular :: (HasCallStack, Conjoined p, Functor f) => Traversing p f s t a b -> Over p f s t a b #

This converts a Traversal that you "know" will target only one element to a Lens. It can also be used to transform a Fold into a Getter.

The resulting Lens or Getter will be partial if the Traversal targets nothing or more than one element.

cloneTraversal :: ATraversal s t a b -> Traversal s t a b #

A Traversal is completely characterized by its behavior on a Bazaar.

Cloning a Traversal is one way to make sure you aren't given something weaker, such as a Fold and can be used as a way to pass around traversals that have to be monomorphic in f.

Note: This only accepts a proper Traversal (or Lens). To clone a Lens as such, use cloneLens.

Note: It is usually better to use ReifiedTraversal and runTraversal than to cloneTraversal. The former can execute at full speed, while the latter needs to round trip through the Bazaar.

>>> let foo l a = (view (getting (cloneTraversal l)) a, set (cloneTraversal l) 10 a)
>>> foo both ("hello","world")
("helloworld",(10,10))

Try the first Traversal (or Fold), falling back on the second Traversal (or Fold) if it returns no entries.

This is only a valid Traversal if the second Traversal is disjoint from the result of the first or returns exactly the same results. These conditions are trivially met when given a Lens, Iso, Getter, Prism or "affine" Traversal -- one that has 0 or 1 target.

Mutatis mutandis for Fold.

failing :: Prism s t a b     -> Prism s t a b     -> Traversal s t a b
failing :: Fold s a          -> Fold s a          -> Fold s a

These cases are also supported, trivially, but are boring, because the left hand side always succeeds.

failing :: Lens s t a b      -> Traversal s t a b -> Traversal s t a b
failing :: Iso s t a b       -> Traversal s t a b -> Traversal s t a b
failing :: Equality s t a b  -> Traversal s t a b -> Traversal s t a b
failing :: Getter s a        -> Fold s a          -> Fold s a

If both of the inputs are indexed, the result is also indexed, so you can apply this to a pair of indexed traversals or indexed folds, obtaining an indexed traversal or indexed fold.

failing :: IndexedTraversal i s t a b -> IndexedTraversal i s t a b -> IndexedTraversal i s t a b
failing :: IndexedFold i s a          -> IndexedFold i s a          -> IndexedFold i s a

confusing :: Applicative f => LensLike (Curried (Yoneda f) (Yoneda f)) s t a b -> LensLike f s t a b #

Fuse a Traversal by reassociating all of the (<*>) operations to the left and fusing all of the fmap calls into one. This is particularly useful when constructing a Traversal using operations from GHC.Generics.

Given a pair of Traversals foo and bar,

confusing (foo.bar) = foo.bar

However, foo and bar are each going to use the Applicative they are given.

confusing exploits the Yoneda lemma to merge their separate uses of fmap into a single fmap. and it further exploits an interesting property of the right Kan lift (or Curried) to left associate all of the uses of (<*>) to make it possible to fuse together more fmaps.

This is particularly effective when the choice of functor f is unknown at compile time or when the Traversal foo.bar in the above description is recursive or complex enough to prevent inlining.

fusing is a version of this combinator suitable for fusing lenses.

confusing :: Traversal s t a b -> Traversal s t a b

traverseByOf :: Traversal s t a b -> (forall x. x -> f x) -> (forall x y. f (x -> y) -> f x -> f y) -> (a -> f b) -> s -> f t #

This is like traverseBy where the Traversable instance can be specified by any Traversal

traverseByOf traverse ≡ traverseBy

sequenceByOf :: Traversal s t (f b) b -> (forall x. x -> f x) -> (forall x y. f (x -> y) -> f x -> f y) -> s -> f t #

sequenceByOf traverse ≡ sequenceBy

ilevels :: Applicative f => Traversing (Indexed i) f s t a b -> IndexedLensLike Int f s t (Level i a) (Level j b) #

This provides a breadth-first Traversal or Fold of the individual levels of any other Traversal or Fold via iterative deepening depth-first search. The levels are returned to you in a compressed format.

This is similar to levels, but retains the index of the original IndexedTraversal, so you can access it when traversing the levels later on.

>>> ["dog","cat"]^@..ilevels (traversed<.>traversed).itraversed
[((0,0),'d'),((0,1),'o'),((1,0),'c'),((0,2),'g'),((1,1),'a'),((1,2),'t')]

The resulting Traversal of the levels which is indexed by the depth of each Level.

>>> ["dog","cat"]^@..ilevels (traversed<.>traversed)<.>itraversed
[((2,(0,0)),'d'),((3,(0,1)),'o'),((3,(1,0)),'c'),((4,(0,2)),'g'),((4,(1,1)),'a'),((5,(1,2)),'t')]

ilevels :: IndexedFold i s a               -> IndexedFold Int s (Level i a)

Note: Internally this is implemented by using an illegal Applicative, as it extracts information in an order that violates the Applicative laws.

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

ifolded :: IndexedFold i (f a) a #

The IndexedFold of a FoldableWithIndex container.

ifolded . asIndex is a fold over the keys of a FoldableWithIndex.

>>> Data.Map.fromList [(2, "hello"), (1, "world")]^..ifolded.asIndex
[1,2]

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 Foldable is more flexible in what it accepts.

Foldable ≡ 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.

foldlOf' l ≡ ifoldlOf' l . const

class Functor f => FunctorWithIndex i (f :: Type -> Type) | f -> i where #

A Functor with an additional index.

Instances must satisfy a modified form of the Functor laws:

imap f . imap g ≡ imap (\i -> f i . g i)
imap (\_ a -> a) ≡ id

Minimal complete definition

Nothing

Methods

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

Map with access to the index.

imapped :: IndexedSetter i (f a) (f b) a b #

The IndexedSetter for a FunctorWithIndex.

If you don't need access to the index, then mapped is more flexible in what it accepts.

selfIndex :: Indexable a p => p a fb -> a -> fb #

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

Build a simple isomorphism from a pair of inverse functions.

view (iso f g) ≡ f
view (from (iso f g)) ≡ g
over (iso f g) h ≡ g . h . f
over (from (iso f g)) h ≡ f . h . g

from :: AnIso s t a b -> Iso b a t s #

Invert an isomorphism.

from (from l) ≡ l

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

Extract the two functions, one from s -> a and one from b -> t that characterize an Iso.

cloneIso :: AnIso s t a b -> Iso s t a b #

Convert from AnIso back to any Iso.

This is useful when you need to store an isomorphism as a data type inside a container and later reconstitute it as an overloaded function.

See cloneLens or cloneTraversal for more information on why you might want to do this.

au :: Functor f => AnIso 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 (_Wrapping Sum) foldMap [1,2,3,4]
10

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

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

auf :: Optic (Costar f) g s t a b -> (f a -> g b) -> f s -> g t #

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

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

For a version you pass the name of the newtype constructor to, see alaf.

>>> auf (_Unwrapping Sum) (foldMapOf both) Prelude.length ("hello","world")
10

Mnemonically, the German auf plays a similar role to à la, and the combinator is au with an extra function argument:

auf :: Iso s t a b -> ((r ->  a) -> e -> b) -> (r -> s) -> e -> t

but the signature is general.

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

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

under ≡ over . from

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

enum :: Enum a => Iso' Int a #

This isomorphism can be used to convert to or from an instance of Enum.

>>> LT^.from enum
0

>>> 97^.enum :: Char
'a'

Note: this is only an isomorphism from the numeric range actually used and it is a bit of a pleasant fiction, since there are questionable Enum instances for Double, and Float that exist solely for [1.0 .. 4.0] sugar and the instances for those and Integer don't cover all values in their range.

mapping :: (Functor f, Functor g) => AnIso s t a b -> Iso (f s) (g t) (f a) (g b) #

This can be used to lift any Iso into an arbitrary Functor.

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 -~ 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:

>>> fromList [("hello",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' :: APrism' a () -> Iso' (Maybe a) a #

non' p generalizes non (p # ()) to take any unit Prism

This function generates an isomorphism between Maybe (a | isn't p a) and a.

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

>>> fromList [("hello",fromList [("world","!!!")])] & at "hello" . non' _Empty . at "world" .~ Nothing
fromList []

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

anon a p generalizes non a to take any value and a predicate.

This function assumes that p a holds True and generates an isomorphism between Maybe (a | not (p a)) and a.

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

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

curried :: Iso ((a, b) -> c) ((d, e) -> f) (a -> b -> c) (d -> e -> f) #

curried = iso curry uncurry

>>> (fst^.curried) 3 4

An Iso between a list, ByteString, Text fragment, etc. and its reversal.

>>> "live" ^. reversed
"evil"

>>> "live" & reversed %~ ('d':)

involuted :: (a -> a) -> Iso' a a #

Given a function that is its own inverse, this gives you an Iso using it in both directions.

involuted ≡ join iso

>>> "live" ^. involuted reverse
"evil"

>>> "live" & involuted reverse %~ ('d':)
"lived"

magma :: LensLike (Mafic a b) s t a b -> Iso s u (Magma Int t b a) (Magma j u c c) #

This isomorphism can be used to inspect a Traversal to see how it associates the structure and it can also be used to bake the Traversal into a Magma so that you can traverse over it multiple times.

imagma :: Over (Indexed i) (Molten i a b) s t a b -> Iso s t' (Magma i t b a) (Magma j t' c c) #

pattern (:<) :: forall b a. Cons b b a a => a -> b -> b infixr 5 #

(<|) :: Cons s s a a => a -> s -> s infixr 5 #

cons an element onto a container.

This is an infix alias for cons.

>>> a <| []
[a]

>>> a <| [b, c]
[a,b,c]

>>> a <| Seq.fromList []
fromList [a]

>>> a <| Seq.fromList [b, c]
fromList [a,b,c]

cons :: Cons s s a a => a -> s -> s infixr 5 #

cons an element onto a container.

>>> cons a []
[a]

>>> cons a [b, c]
[a,b,c]

>>> cons a (Seq.fromList [])
fromList [a]

>>> cons a (Seq.fromList [b, c])
fromList [a,b,c]

uncons :: Cons s s a a => s -> Maybe (a, s) #

Attempt to extract the left-most element from a container, and a version of the container without that element.

>>> uncons []
Nothing

>>> uncons [a, b, c]
Just (a,[b,c])

_head :: Cons s s a a => Traversal' s a #

A Traversal reading and writing to the head of a non-empty container.

>>> [a,b,c]^? _head
Just a

>>> [a,b,c] & _head .~ d
[d,b,c]

>>> [a,b,c] & _head %~ f
[f a,b,c]

>>> [] & _head %~ f
[]

>>> [1,2,3]^?!_head
1

>>> []^?_head
Nothing

>>> [1,2]^?_head
Just 1

>>> [] & _head .~ 1
[]

>>> [0] & _head .~ 2
[2]

>>> [0,1] & _head .~ 2
[2,1]

This isn't limited to lists.

For instance you can also traverse the head of a Seq:

>>> Seq.fromList [a,b,c,d] & _head %~ f
fromList [f a,b,c,d]

>>> Seq.fromList [] ^? _head
Nothing

>>> Seq.fromList [a,b,c,d] ^? _head
Just a

_head :: Traversal' [a] a
_head :: Traversal' (Seq a) a
_head :: Traversal' (Vector a) a

_tail :: Cons s s a a => Traversal' s s #

A Traversal reading and writing to the tail of a non-empty container.

>>> [a,b] & _tail .~ [c,d,e]
[a,c,d,e]

>>> [] & _tail .~ [a,b]
[]

>>> [a,b,c,d,e] & _tail.traverse %~ f
[a,f b,f c,f d,f e]

>>> [1,2] & _tail .~ [3,4,5]
[1,3,4,5]

>>> [] & _tail .~ [1,2]
[]

>>> [a,b,c]^?_tail
Just [b,c]

>>> [1,2]^?!_tail
[2]

>>> "hello"^._tail
"ello"

>>> ""^._tail
""

This isn't limited to lists. For instance you can also traverse the tail of a Seq.

>>> Seq.fromList [a,b] & _tail .~ Seq.fromList [c,d,e]
fromList [a,c,d,e]

>>> Seq.fromList [a,b,c] ^? _tail
Just (fromList [b,c])

>>> Seq.fromList [] ^? _tail
Nothing

_tail :: Traversal' [a] [a]
_tail :: Traversal' (Seq a) (Seq a)
_tail :: Traversal' (Vector a) (Vector a)

_init :: Snoc s s a a => Traversal' s s #

A Traversal reading and replacing all but the a last element of a non-empty container.

>>> [a,b,c,d]^?_init
Just [a,b,c]

>>> []^?_init
Nothing

>>> [a,b] & _init .~ [c,d,e]
[c,d,e,b]

>>> [] & _init .~ [a,b]
[]

>>> [a,b,c,d] & _init.traverse %~ f
[f a,f b,f c,d]

>>> [1,2,3]^?_init
Just [1,2]

>>> [1,2,3,4]^?!_init
[1,2,3]

>>> "hello"^._init
"hell"

>>> ""^._init
""

_init :: Traversal' [a] [a]
_init :: Traversal' (Seq a) (Seq a)
_init :: Traversal' (Vector a) (Vector a)

_last :: Snoc s s a a => Traversal' s a #

A Traversal reading and writing to the last element of a non-empty container.

>>> [a,b,c]^?!_last
c

>>> []^?_last
Nothing

>>> [a,b,c] & _last %~ f
[a,b,f c]

>>> [1,2]^?_last
Just 2

>>> [] & _last .~ 1
[]

>>> [0] & _last .~ 2
[2]

>>> [0,1] & _last .~ 2
[0,2]

This Traversal is not limited to lists, however. We can also work with other containers, such as a Vector.

>>> Vector.fromList "abcde" ^? _last
Just 'e'

>>> Vector.empty ^? _last
Nothing

>>> (Vector.fromList "abcde" & _last .~ 'Q') == Vector.fromList "abcdQ"
True

_last :: Traversal' [a] a
_last :: Traversal' (Seq a) a
_last :: Traversal' (Vector a) a

(|>) :: Snoc s s a a => s -> a -> s infixl 5 #

snoc an element onto the end of a container.

This is an infix alias for snoc.

>>> Seq.fromList [] |> a
fromList [a]

>>> Seq.fromList [b, c] |> a
fromList [b,c,a]

>>> LazyT.pack "hello" |> '!'
"hello!"

snoc :: Snoc s s a a => s -> a -> s infixl 5 #

snoc an element onto the end of a container.

>>> snoc (Seq.fromList []) a
fromList [a]

>>> snoc (Seq.fromList [b, c]) a
fromList [b,c,a]

>>> snoc (LazyT.pack "hello") '!'
"hello!"

unsnoc :: Snoc s s a a => s -> Maybe (s, a) #

Attempt to extract the right-most element from a container, and a version of the container without that element.

>>> unsnoc (LazyT.pack "hello!")
Just ("hello",'!')

>>> unsnoc (LazyT.pack "")
Nothing

>>> unsnoc (Seq.fromList [b,c,a])
Just (fromList [b,c],a)

>>> unsnoc (Seq.fromList [])
Nothing

class Wrapped s where #

Wrapped provides isomorphisms to wrap and unwrap newtypes or data types with one constructor.

Minimal complete definition

Nothing

Associated Types

type Unwrapped s :: Type #

Methods

_Wrapped' :: Iso' s (Unwrapped s) #

An isomorphism between s and a.

If your type has a Generic instance, _Wrapped' will default to _GWrapped', and you can choose to not override it with your own definition.

class (Magnified m ~ Magnified n, 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 use 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.

Also, unlike zoom, this can be used with any valid Getter, but cannot be used with a Traversal or Fold.

Methods

magnify :: LensLike' (Magnified m c) a b -> m c -> n c infixr 2 #

Run a monadic action in a larger environment than it was defined in, using a Getter.

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

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

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

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

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

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

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 use zoom in, changing the State supplied by many different Monad transformers, potentially quite deep in a Monad transformer stack.

Methods

zoom :: LensLike' (Zoomed m c) t s -> m c -> n c infixr 2 #

Run a monadic action in a larger State than it was defined in, using a Lens' or Traversal'.

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

When applied to 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 State.evalState (a,b) $ zoom _1 $ use id
a

>>> flip State.execState (a,b) $ zoom _1 $ id .= c
(c,b)

>>> flip State.execState [(a,b),(c,d)] $ zoom traverse $ _2 %= f
[(a,f b),(c,f d)]

>>> flip State.runState [(a,b),(c,d)] $ zoom traverse $ _2 <%= f
(f b <> f d <> mempty,[(a,f b),(c,f d)])

>>> flip State.evalState (a,b) $ zoom both (use id)
a <> b

class Plated a where #

A Plated type is one where we know how to extract its immediate self-similar children.

Example 1:

import Control.Applicative
import Control.Lens
import Control.Lens.Plated
import Data.Data
import Data.Data.Lens (uniplate)

data Expr
  = Val Int
  | Neg Expr
  | Add Expr Expr
  deriving (Eq,Ord,Show,Read,Data,Typeable)

instance Plated Expr where
  plate f (Neg e) = Neg <$> f e
  plate f (Add a b) = Add <$> f a <*> f b
  plate _ a = pure a

or

instance Plated Expr where
  plate = uniplate

Example 2:

import Control.Applicative
import Control.Lens
import Control.Lens.Plated
import Data.Data
import Data.Data.Lens (uniplate)

data Tree a
  = Bin (Tree a) (Tree a)
  | Tip a
  deriving (Eq,Ord,Show,Read,Data,Typeable)

instance Plated (Tree a) where
  plate f (Bin l r) = Bin <$> f l <*> f r
  plate _ t = pure t

or

instance Data a => Plated (Tree a) where
  plate = uniplate

Note the big distinction between these two implementations.

The former will only treat children directly in this tree as descendents, the latter will treat trees contained in the values under the tips also as descendants!

When in doubt, pick a Traversal and just use the various ...Of combinators rather than pollute Plated with orphan instances!

If you want to find something unplated and non-recursive with biplate use the ...OnOf variant with ignored, though those usecases are much better served in most cases by using the existing Lens combinators! e.g.

toListOf biplate ≡ universeOnOf biplate ignored

This same ability to explicitly pass the Traversal in question is why there is no analogue to uniplate's Biplate.

Moreover, since we can allow custom traversals, we implement reasonable defaults for polymorphic data types, that only traverse into themselves, and not their polymorphic arguments.

deep :: (Conjoined p, Applicative f, Plated s) => Traversing p f s s a b -> Over p f s s a b #

deep :: Plated s => Traversal s s a b        -> Traversal s s a b
deep :: Plated s => IndexedTraversal s s a b -> IndexedTraversal s s a b

rewrite :: Plated a => (a -> Maybe a) -> a -> a #

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

propRewrite r x = all (isNothing . r) (universe (rewrite r x))

Usually transform is more appropriate, but rewrite can give better compositionality. Given two single transformations f and g, you can construct \a -> f a <|> g a which performs both rewrites until a fixed point.

rewriteOf :: ASetter 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))

Usually transformOf is more appropriate, but rewriteOf can give better compositionality. Given two single transformations f and g, you can construct \a -> f a <|> g a which performs both rewrites until a fixed point.

The resulting Lens is safer to use as it ignores 'over-application' and deals gracefully with under-application, but it is only a proper Lens if you don't change the list length!

gplate :: (Generic a, GPlated a (Rep a)) => Traversal' a a #

Implement plate operation for a type using its Generic instance.

gplate1 :: (Generic1 f, GPlated1 f (Rep1 f)) => Traversal' (f a) (f a) #

Implement plate operation for a type using its Generic1 instance.

class Each s t a b | s -> a, t -> b, s b -> t, t a -> s where #

Extract each element of a (potentially monomorphic) container.

Notably, when applied to a tuple, this generalizes both to arbitrary homogeneous tuples.

>>> (1,2,3) & each *~ 10
(10,20,30)

It can also be used on monomorphic containers like Text or ByteString.

>>> over each Char.toUpper ("hello"^.Text.packed)
"HELLO"

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.

type ClassyNamer #

Arguments

= Name	Name of the data type that lenses are being generated for.
-> Maybe (Name, Name)	Names of the class and the main method it generates, respectively.

The optional rule to create a class and method around a monomorphic data type. If this naming convention is provided, it generates a "classy" lens.

data DefName #

Name to give to generated field optics.

Constructors

TopName Name	Simple top-level definiton name
MethodName Name Name	makeFields-style class name and method name

Instances

Eq DefName
Instance details Defined in Control.Lens.Internal.FieldTH Methods (==) :: DefName -> DefName -> Bool # (/=) :: DefName -> DefName -> Bool #
Ord DefName
Instance details Defined in Control.Lens.Internal.FieldTH Methods compare :: DefName -> DefName -> Ordering # (<) :: DefName -> DefName -> Bool # (<=) :: DefName -> DefName -> Bool # (>) :: DefName -> DefName -> Bool # (>=) :: DefName -> DefName -> Bool # max :: DefName -> DefName -> DefName # min :: DefName -> DefName -> DefName #
Show DefName
Instance details Defined in Control.Lens.Internal.FieldTH Methods showsPrec :: Int -> DefName -> ShowS # show :: DefName -> String # showList :: [DefName] -> ShowS #

type FieldNamer #

Arguments

= Name	Name of the data type that lenses are being generated for.
-> [Name]	Names of all fields (including the field being named) in the data type.
-> Name	Name of the field being named.
-> [DefName]	Name(s) of the lens functions. If empty, no lens is created for that field.

The rule to create function names of lenses for data fields.

Although it's sometimes useful, you won't need the first two arguments most of the time.

data LensRules #

Rules to construct lenses for data 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, Folds will be generated instead of 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 $!:

strictOptic = ($!) . lazyOptic

createClass :: Lens' LensRules Bool #

Create the class if the constructor is Simple 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 fairly simple partial lenses, ignoring the special cases for isomorphisms and traversals, and not making any classes. It uses underscoreNoPrefixNamer.

underscoreNoPrefixNamer :: FieldNamer #

A FieldNamer that strips the _ off of the field name, lowercases the name, and skips the field if it doesn't start with an '_'.

lensRulesFor #

Arguments

:: [(String, String)]	(Field Name, Definition Name)
-> LensRules

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

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

Create a FieldNamer from explicit pairings of (fieldName, lensName).

mappingNamer #

Arguments

:: (String -> [String])	A function that maps a `fieldName` to `lensName`s.
-> FieldNamer

Create a FieldNamer from a mapping function. If the function returns [], it creates no lens for the field.

classyRules :: LensRules #

Rules for making lenses and traversals that precompose another Lens.

classyRules_ :: LensRules #

A LensRules used by makeClassy_.

makeLenses :: Name -> DecsQ #

Build lenses (and traversals) with a sensible default configuration.

e.g.

data FooBar
  = Foo { _x, _y :: Int }
  | Bar { _x :: Int }
makeLenses ''FooBar

will create

x :: Lens' FooBar Int
x f (Foo a b) = (\a' -> Foo a' b) <$> f a
x f (Bar a)   = Bar <$> f a
y :: Traversal' FooBar Int
y f (Foo a b) = (\b' -> Foo a  b') <$> f b
y _ c@(Bar _) = pure c

makeLenses = makeLensesWith lensRules

makeClassy :: Name -> DecsQ #

Make lenses and traversals for a type, and create a class when the type has no arguments.

e.g.

data Foo = Foo { _fooX, _fooY :: Int }
makeClassy ''Foo

will create

class HasFoo t where
  foo :: Lens' t Foo
  fooX :: Lens' t Int
  fooX = foo . go where go f (Foo x y) = (\x' -> Foo x' y) <$> f x
  fooY :: Lens' t Int
  fooY = foo . go where go f (Foo x y) = (\y' -> Foo x y') <$> f y
instance HasFoo Foo where
  foo = id

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 lenses and traversals, specifying explicit pairings of (fieldName, lensName).

If you map multiple names to the same label, and it is present in the same constructor then this will generate a Traversal.

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 lenses with a custom configuration.

declareLenses :: DecsQ -> DecsQ #

Make lenses 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)

declareWrapped :: DecsQ -> DecsQ #

Build Wrapped instance for each newtype.

declareFields :: DecsQ -> DecsQ #

 declareFields = declareLensesWith defaultFieldRules

declareLensesWith :: LensRules -> DecsQ -> DecsQ #

Declare lenses for each records in the given declarations, using the specified LensRules. Any record syntax in the input will be stripped off.

makeWrapped :: Name -> DecsQ #

Build Wrapped instance for a given newtype

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

_fooXLens :: Lens' (Foo a) Int
_fooYLens :: Lens (Foo a) (Foo b) a b
class HasX s a | s -> a where
  x :: Lens' s a
instance HasX (Foo a) Int where
  x = _fooXLens
class HasY s a | s -> a where
  y :: Lens' s a
instance HasY (Foo a) a where
  y = _fooYLens
_barXLens :: Iso' Bar Char
instance HasX Bar Char where
  x = _barXLens

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.

makeFieldsNoPrefix = makeLensesWith classUnderscoreNoPrefixFields

defaultFieldRules :: LensRules #

class Profunctor (p :: Type -> Type -> Type) where #

Formally, the class Profunctor represents a profunctor from Hask -> Hask.

Intuitively it is a bifunctor where the first argument is contravariant and the second argument is covariant.

You can define a Profunctor by either defining dimap or by defining both lmap and rmap.

If you supply dimap, you should ensure that:

dimap id id ≡ id

If you supply lmap and rmap, ensure:

lmap id ≡ id
rmap id ≡ id

If you supply both, you should also ensure:

dimap f g ≡ lmap f . rmap g

These ensure by parametricity:

dimap (f . g) (h . i) ≡ dimap g h . dimap f i
lmap (f . g) ≡ lmap g . lmap f
rmap (f . g) ≡ rmap f . rmap g

Minimal complete definition

dimap | lmap, rmap

Methods

dimap :: (a -> b) -> (c -> d) -> p b c -> p a d #

Map over both arguments at the same time.

dimap f g ≡ lmap f . rmap g

lmap :: (a -> b) -> p b c -> p a c #

Map the first argument contravariantly.

lmap f ≡ dimap f id

rmap :: (b -> c) -> p a b -> p a c #

Map the second argument covariantly.

rmap ≡ dimap id
