Quark v2.1.0 Quark.Partial

Provide curried functions, that can also be partially bound without dot notation. Partially applying a function will always return a fully-curried function.

Please note that these will use all of the arities up to the defined function.

For instance:

defpartial foo(a, b, c), do: a + b + c
#=> foo/0, foo/1, foo/2, and foo/3

If you need to use an arity in the range below the original function, fall back to defcurry and partially apply manually.

Summary

Macros

A convenience on defcurry. Generates a series of partially-bound applications of a fully-curried function, for all arities at and below the user-specified arity

defpartial, but generates private functions

Macros

defpartial(arg, list)

A convenience on defcurry. Generates a series of partially-bound applications of a fully-curried function, for all arities at and below the user-specified arity.

For instance:

defpartial add(a,b), do: a + b
#=> add/0, add/1, add/2.

Examples

defpartialp minus(a, b, c), do: a - b - c
minus(3, 2, 1)
0

minus.(3).(2).(1)
0

below_ten = minus(5)
below_ten.(2, 1)
7

below_five = minus(20, 15)
below_five.(2)
3
