# 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
