Converting bool to *bool in go

Question

With the following code:

var example *bool
example = true
log.Print(example)

I have the following error cannot convert true (untyped bool constant) to *bool

I manage to solve it declaring a new variable truevalue:

var example *bool
truevalue := true
example = &truevalue
log.Print(example)

But I imagine there is a better way to do it, without declaring any new variables.

Answer 1

A pointer has to point to something, which means you have to either assign it to the address of another variable (as in your second example), or initialize it with new() and then assign by dereference. Personally I'd recommend the former, as new is not widely used in Go. But, for demonstration:

example := new(bool)
*example = true
