lang

Package lang provides some helpful or at least amusing language features not included in the standard Go language or libraries.

Motivation

The helpers provided by package lang are inspired by the lack of some basic language features in the Go language or libraries.

If/Else

Say we want to conditionally set the value of a string - one that could be a const in another language, written only on initialization, but conditionally.

e.g.

final String s = (true) ? "foo" : "bar"

In Go we cannot do this, instead we must write something like,

s := "foo"
if true {
    s = "bar"
}

This grinds my gears. Why waste 4 lines of code on something that could be 1 line?

Now, we can!

s := lang.If(true, "foo").Else("bar")

Index

• func If[A any](b bool, v1 A) evaluation[A]
• type Pair

Functions

func If

func If[A any](b bool, v1 A) evaluation[A]

If can be chained together with Else to create type-safe one-line if/else expressions in Go.

e.g.

v := If(expression, value).Else(default)

Types

type Pair

type Pair[T, U any] struct {
	A T
	B U
}

A Pair contains two elements of any type(s).
