What are Cantrips?

2. chiefly British: hocus-pocus.
   
   

Cantrips are small (magical) utility functions to achieve common tasks in Go. The name was inspired by Svelte 5's Runes and Baldur's Gate 3.

For example the Pop() function will remove the last element from a slice and return that element.

package main

import (
	"fmt"
	"github.com/banaaron/cantrips"
)

func main() {
	names := []string{"aaron", "chris", "drew"}
	n := cantrips.Pop(&names)
	fmt.Println(n)     // "drew"
	fmt.Println(names) // ["aaron", "chris"]

	// you can provide an index to remove an element at a specific index
	p := cantrips.Pop(&names, 1)
	fmt.Println(p)     // "chris"
	fmt.Println(names) // ["aaron"]
}
