CompositionsBase.jl: exports ∘, ⨟, compose, and opcompose

API

f ∘ g
g ⨟ f
compose(f, g)
opcompose(g, f)

Composition of morphisms. ∘ is the operator defined in Base. CompositionsBase.jl defines the opposite composition operator ⨟ as

⨟(fs...) = ∘(reverse(fs)...)

and also the ASCII aliases compose and opcompose.

As ⨟, compose, and opcompose are all defined in terms of ∘, single-argument call is the identity function.

Examples

julia> using CompositionsBase

julia> tuple ∘ inv === compose(tuple, inv) === inv ⨟ tuple === opcompose(inv, tuple)
true

julia> ∘(tuple) === compose(tuple) === ⨟(tuple) === opcompose(tuple) === tuple
true

g ⨟ f
opcompose(g, f)

The opposite composition operator defined as

g ⨟ f = f ∘ g
⨟(f) = f
⨟(fs...) = ∘(reverse(fs)...)

g ⨟ f
opcompose(g, f)

The opposite composition operator defined as

g ⨟ f = f ∘ g
⨟(f) = f
⨟(fs...) = ∘(reverse(fs)...)
