Inverted syntax: Difference between revisions

</pre>

=={{header|Go}}==

The closest Go can get to inverted syntax for conditionals is to define a new type ('ibool' say) based on the built-in 'bool' type and then define a method ('iif' say) on the new type which takes the place of the traditional 'if'.

<lang go>package main

import "fmt"

type ibool bool

const itrue ibool = true

func (ib ibool) iif(cond bool) bool {

if cond {

return bool(ib)

}

return bool(!ib)

}

func main() {

var needUmbrella bool

raining := true

// normal syntax

if raining {

needUmbrella = true

}

fmt.Printf("Is it raining? %t. Do I need an umbrella? %t\n", raining, needUmbrella)

// inverted syntax

raining = false

needUmbrella = itrue.iif(raining)

fmt.Printf("Is it raining? %t. Do I need an umbrella? %t\n", raining, needUmbrella)

}</lang>

Is it raining? true. Do I need an umbrella? true

Is it raining? false. Do I need an umbrella? false
