Curry

Curry provides facilities for currying Go functions. The process converts a single function like f(x, y, z) into N many functions each taking a single argument like h(x)(y)(z).

Currying can be useful as a way to provide partial function application. For example, this takes a function that adds two integers and creates a new function plus1 that increments the given value by 1.

package main

import (
  "fmt"

  "github.com/calebcase/curry"
)

func Add(x, y int) int {
  return x + y
}

func main() {
  // Create a reusable function with the first argument bound to 1.
  plus1 := curry.A2R1(Add)(1)

  fmt.Println(plus1(2)) // 3
  fmt.Println(plus1(3)) // 4
  fmt.Println(plus1(4)) // 5
}

For more examples and usage see the go docs.
