Ternary

Don't write 4 lines of code when 1 will do.

-- Not a Go proverb

This completely useless package uses Go's new generics to add a ternary operator style syntax to Go! You know there have been at least a handful of times where you've quit your working day early because you just could not write one more if statement. Well now you don't have to, feel free to replace all of your if statements with this the beautiful and not-confusing-at-all syntax provided by ternary.

Because this requires Generics, you must be using go 1.18.

Installation

go get github.com/troylelandshields/ternary

Usage

Simple Example

var x = -9
absoluteValue := Give(x).If(x > 0).Else(-x)
fmt.Println(absoluteValue)

Interface Example

type Nameable interface {
    Name() string
}

type Cat struct {
    name string
}

func (c Cat) Name() string {
    return c.name
}

type Dog struct {
    name string
}

func (d Dog) Name() string {
    return d.name
}

func main() {
	var d *Dog
	c := &Cat{
		name: "Roger",
	}

	fmt.Println(Give[Nameable](d).If(d != nil).Else(c).Name())
}
