Description

Compatibility layer for Data.Semigroup

Synopsis

Documentation

class Semigroup a where Source #

The class of semigroups (types with an associative binary operation).

Instances should satisfy the following:

Associativity
x <> (y <> z) = (x <> y) <> z

Since: base-4.9.0.0

Methods

(<>) :: a -> a -> a infixr 6 Source #

An associative operation.

>>> [1,2,3] <> [4,5,6]
[1,2,3,4,5,6]

class Semigroup a => Monoid a where Source #

The class of monoids (types with an associative binary operation that has an identity). Instances should satisfy the following:

Right identity
x <> mempty = x
Left identity
mempty <> x = x
Associativity
x <> (y <> z) = (x <> y) <> z (Semigroup law)
Concatenation
mconcat = foldr (<>) mempty

The method names refer to the monoid of lists under concatenation, but there are many other instances.

Some types can be viewed as a monoid in more than one way, e.g. both addition and multiplication on numbers. In such cases we often define newtypes and make those instances of Monoid, e.g. Sum and Product.

NOTE: Semigroup is a superclass of Monoid since base-4.11.0.0.

Minimal complete definition

mempty

Methods

mempty :: a Source #

Identity of mappend

>>> "Hello world" <> mempty
"Hello world"

mappend :: a -> a -> a Source #

An associative operation

NOTE: This method is redundant and has the default implementation mappend = (<>) since base-4.11.0.0. Should it be implemented manually, since mappend is a synonym for (<>), it is expected that the two functions are defined the same way. In a future GHC release mappend will be removed from Monoid.

mconcat :: [a] -> a Source #

Fold a list using the monoid.

For most types, the default definition for mconcat will be used, but the function is included in the class definition so that an optimized version can be provided for specific types.

>>> mconcat ["Hello", " ", "Haskell", "!"]
"Hello Haskell!"

Monoid Library Source #

This instance is not good.

We need it for addBuildableCondition. More correct method would be some kind of "create empty clone".

More concretely, addBuildableCondition will make `libVisibility = False` libraries when `buildable: false`. This may cause problems.

Ord a => Monoid (NubList a) Source #

Monoid operations on NubLists. For a valid Monoid instance we need to satistfy the required monoid laws; identity, associativity and closure.

Identity : by inspection: mempty mappend NubList xs == NubList xs mappend mempty

Associativity : by inspection: (NubList xs mappend NubList ys) mappend NubList zs == NubList xs mappend (NubList ys mappend NubList zs)

Closure : appending two lists of type a and removing duplicates obviously does not change the type.

gmappend :: (Generic a, GSemigroup (Rep a)) => a -> a -> a Source #

Generically generate a Semigroup (<>) operation for any type implementing Generic. This operation will append two values by point-wise appending their component fields. It is only defined for product types.

gmappend a (gmappend b c) = gmappend (gmappend a b) c

Generically generate a Monoid mempty for any product-like type implementing Generic.

It is only defined for product types.
