Go ternary

The missing ternary operator for Go.

It's a blazing fast, 7 lines of code package that will save you a lot of lines of code over readability.

Honestly, don't take this package too seriously. It's just a joke to keep me busy one evening.

Installation

go get github.com/julien040/go-ternary

Usage/Examples

import (
    "github.com/julien040/go-ternary"
)

ternary.If(true, "foo", "bar") // "foo"
ternary.If(false, "foo", "bar") // "bar"

// Use it for pluralization
ternary.If(len(slice) > 2, "objects", "object") // "objects"

ternary.If(true, 5.4, 3.2) // 5.4

FAQ

Which type can I use?

Thanks to generics, you can use any type you want.

What is the minimum Go version?

Because of generics, you need at least Go 1.18.

Contributing

Contributions are always welcome!

I accept any contribution, from code to documentation, bug reports, and feature requests.

However, I wonder if there is much to contribute to this project since it's pretty simple.

Functions

func If

func If[T any](condition bool, a, b T) T

If is the replacement ternary operator in Go

Usage:

ternary.If(condition bool, elementReturnedIfTrue, elementReturnedIfFalse)

Example:

ternary.If(true, "foo", "bar") // returns "foo"
ternary.If(false, "foo", "bar") // returns "bar"

func IfFunc

func IfFunc[T any, R any](condition bool, a, b T, f func(T) R) R

IfFunc implements a given function using the chosen element as parameter

Usage:

ternary.If(condition bool, elementPassedIfTrue, elementPassedIfFalse, function func(element))

Example:

ternary.If(true, "foo", "bar", func(e any) {
	return fmt.Sprintf("%v", e)
}) // returns "foo"
