Go Type Tools
A library containing useful functions for working with Go types.
Table of Contents
Reasoning
One of the main reasons I wanted to create this library was becuause of the lack of functionality in the standard library. Common things like filters, union, intersection, etc. are not available in the standard library. This library is meant to be a collection of useful functions for working with Go types, improve readability and reduce boilerplate.

Examples
Here are some examples of how/when to use this library.
Array
Filter
package main
func main() {
// Create a new array of strings
arr := []string{"a", "b", "c"}
// Filter the array
filtered := arraytools.Filter(arr, func(item string) bool {
return item == "b"
})
// Print the filtered array
fmt.Println(filtered)
}
Union
package main
func main() {
// Create a new array of strings
arr1 := []string{"a", "b", "c"}
arr2 := []string{"c", "d", "e"}
// Union the arrays
union := arraytools.Union(arr1, arr2)
// Print the union
fmt.Println(union)
}
Map
Filter
package main
func main() {
// Create a new map of strings
m := map[string]string{
"a": "1",
"b": "2",
"c": "3",
}
// Filter the map
filtered := maptools.Filter(m, func(key string, value string) bool {
return value == "2"
})
// Print the filtered map
fmt.Println(filtered)
}
String
ToIntArray
package main
func main() {
// Create a new string
s := "2313,543,1"
// To int array
ints := stringtools.ToIntArray(s, ",")
// Print the int array
fmt.Println(ints)
}
Int
SecondsToDays
package main
func main() {
// Create a new int
i := inttools.SecondsToDays(86400)
// Print the int
fmt.Println(i)
}
