groovy: how to pass varargs and closure in same time to a method?

Question

Given following groovy function:

def foo(List params, Closure c) {...}

The method call would be:

foo([\'a\', \'b         


        

Answer 1

Seeing that it's impossible to achieve exactly what you want (it's written in Groovy documentation that your specific case is a problem, unfortunately they are migrating the docs so I can't directly link right now), what about something along these lines:

def foo(String... params) {
    println params
    return { Closure c ->
        c.call()
    }
}

foo('a', 'b') ({ println 'woot' })

Now you need to put the closure in parantheses, but you don't need to use an array anymore..
