(many $ char a) >> (many $ char b)
(many $ char a) *> (many $ char b)

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

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.

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.

Monoid Library #

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) #

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.
