Go Extended Library (extlib)

extlib is a collection of idiomatic Go utilities, containers, and helpers to extend the standard library. It is designed for Go 1.20+ and makes common tasks like math operations, slice manipulation, and stack/queue management easier and type-safe using generics.

Features

• Containers (containers)
  • Stack (LIFO)
  • Queue (FIFO)
  • Set
• Math Utilities (mathx)
  • Max, Min, Clamp, Abs
  • Sum, Product
  • Factorial
  • Check if a number is a power of any base (IsPowerOf)
• Slice Utilities (slicex)
  • Reverse slices
  • Map and Filter functions
  • Contains check
• String Utilities (stringx)
  • Rune-safe reverse
  • PadLeft/PadRight
  • Case-insensitive equals
• General Utilities (util)
  • Ternop (ternary operator)
  • Prt (shortcut for printing)

Installation

go get github.com/yourusername/extlib

Usage

package main

import (
    "fmt"

    "github.com/yourusername/extlib/mathx"
    "github.com/yourusername/extlib/slicex"
)

func main() {
    fmt.Println(mathx.Max(10, 20))                  // 20
    fmt.Println(mathx.IsPowerOf(16, 4))             // true
    nums := []int{1, 2, 3, 4}
    slicex.Reverse(nums)
    fmt.Println(nums)                               // [4 3 2 1]
}
