Ruby或等于的golang版本|| =

问题描述：

Out of curiosity, what would be the idiomatic way to assign a variable if it's nil in go?

I'm looking for something similar to ruby's foo ||= bar

Is there a shorter version of this?

if foo == nil{  
  foo = bar
}

出于好奇，如果变量go变为nil，惯用的方式是什么？ p>

我正在寻找与ruby的foo || = bar code> p> p>

类似的东西吗？ p>


 如果foo == nil {
 foo = bar 
} 
  code>  pre> 
  div>

答

Your version is already the simplest, shortest and idiomatic way to do it.
