Varargs

Reported by: Mat Owned by: Jpm
Milestone: Component: AutoIt
Version: Severity: None
Keywords: varargs, params Cc:

Description

A syntax like C# would probably be the easiest, example would be:

Foo(42, 24, "Hello", "World", "!!!")

Func Foo($x, $y, Params $bar)
    For $i = 0 To UBound($bar) - 1
        ConsoleWrite($bar[$i] & @LF)
    Next
EndFunc

Maybe like this.

Func Foo($x, $y, ...)
    For $param In @Params
        ConsoleWrite($param & @LF)
    Next
EndFunc

I would suggest this syntax.

Func f (...$argArray)
	; Use the argument array.
EndFunc

It is done the same way in other languages.

// C++
template <typename... types>
void f (types &&... argArray);

template <int... sizes>
void print (const char (&... arrayReferences) [sizes]);


// JS
function apply (f, ...argArray) { /* ... */ }

It would be useful to allow ByRef and Const before the ellipsis (_ArrayConcatenate (ByRef $to, Const ByRef ...$from)).

  • Owner set to Jpm
  • Status changed from reopened to assigned

I introduce a new keyword in Func() definition to allow handling the variable number of parameter

f(1, 2)

Func f (ByVarArgs $argArray)
	For $i = 1 to @NumParams
		
	; use $argArray[$i]
	Next
EndFunc

Fix sent to Jon
