fp::curry
-- curry a n-ary
functionfp::curry
(f)
returns the higher-order
function x -> (y -> f(x,y)).
fp::curry(f <, n>)
f |
- | n-ary function |
n |
- | nonnegative integer |
A unary higher-order function.
fp::curry
returns the curried version of the
n
-ary function f
. If no arity n
is given, then the function is assumend to be binary.n
is smaller than 2 then f
is
returned. Otherwise, given a n-ary function f,
fp::curry
returns the function
x[1] -> (x[2] -> ... (x[n] -> f(x[1],...,x[n]))...)
Create curried versions of binary and 3-nary functions:
>> cf := fp::curry(f): cf(x)(y)
f(x, y)
>> cg := fp::curry(g, 3): cg(x)(y)(z)
g(x, y, z)
A curried version of _plus
may be used to
create a function which increments its argument by 1
:
>> inc := fp::curry(_plus)(1): inc(x)
x + 1
