#2503 closed Feature Request (Rejected)
Reference Definition Keyword
Reported by: | Tasiro | Owned by: | |
---|---|---|---|
Milestone: | Component: | AutoIt | |
Version: | Severity: | None | |
Keywords: | reference, ref, byref | Cc: |
Description
It is possible to create a reference, but only with a complicated syntax:
Local $var = 1 rest ($var) Func rest (ByRef $var_ref) $var = 2 ; $var_ref == 2 $var_ref = 3 ; $var == 3 EndFunc
Please change the syntax to make the definition of references easier.
The production is something like:
variable-declaration → variable-declaration-specifiers variable-name.
Please change that to:
variable-declaration → variable-declaration-specifiers Refopt variable-name.
Then, it would just be:
Local $var = 1 Local Ref $var_ref = $var ; same rules as for ByRef argument $var = 2 ; $var_ref == 2 $var_ref = 3 ; $var == 3

Why do you need the exactly the same content in variable in the same scope but with different variable name ?
To me this seems ridiculous, or at least unnecessary.

Maybe for this:
ref $r = $array [calculateIndex ()]
Or something similar to this:
func getFirstNonArray (ByRef $array, $then) ref $r = $array while IsArray ($r) ref $r = $r [0] wend $then ($r) endfunc func exampleThen (ByRef $part) ; modify $part endfunc
Creating a reference makes iterative variants of otherwise stack overflow generating functions possible.

So I little change you example (now is be more readeble):
Func getFirstNonArray(ByRef $array, $function) ref $aTemp = $array While IsArray($aTemp) ref $aTemp = $aTemp[0] WEnd $function($aTemp) EndFunc ;==>getFirstNonArray Func exampleThen(ByRef $part) ; modify $part EndFunc ;==>exampleThen
Your example does exactly the same as this:
Func getFirstNonArray(ByRef $array, $function) While IsArray($array) $array = $array[0] WEnd $function($array) EndFunc ;==>getFirstNonArray Func exampleThen(ByRef $part) ; modify $part EndFunc ;==>exampleThen
What advantage do you see in your example ?
