go-collection

go collection is a tool implemented using generic, it can help you process slice/map data quickly and easily convert between them.

Note: To use this project, you need to upgrade to go1.18 version. Some methods cannot be implemented in the 1.18 version, and will be supported after version 1.19 supports type methods.

🚀 Install

go get -u github.com/wwaayyaa/go-collection

✏️ Usage

import collect "github.com/wwaayyaa/go-collection"

Slice example

// filter  
NewSlice[int]([]int{1, 2, 3, 4, 5, 6}).
Filter(func (x int) bool { return x <= 3 }).
All() // [1,2,3]

//join
NewSlice[int]([]int{1, 2, 3, 4, 5, 6}).
Except(func (x int) bool { return x <= 3 }).
Join(func (v int) string { return strconv.Itoa(v) }, "-")
// 1-2-3

//map
NewSlice[string]([]string{"world", "girl"}).
Map(func (k int, v string) string { return "hello " + v }).
All() // ["hello world", "hello girl"]

Maps example

//["a", "z"]
NewMapCollection(map[string]int{"a": 1, "z": 100}).Keys()

//[1, 100]
NewMapCollection(map[string]int{"a": 1, "z": 100}).Values()
