Feature Request: Array as an parameter for Call Function instead of n parameters

[TheDcoder]

Hello Everyone , I want to propose a new feature for the Call function:

I think it would be better if Call function can accept an array for the parameters of the function to call instead of n number of parameters because it will allow UDFs to call a function with a dynamic number of parameters like this:

Call ( "function" , $aParameters)

$aParameter[0] = Number of parameters (0 if none.)

$aParameter[1] = 1st parameter

...

$aParameter[n] = nth Parameter

Here is the Trac Link

TheDcoder,

You mean like this example?

#include <Array.au3>
#include <MsgBoxConstants.au3>

Local $aArray[] = ["I", "am", "an", "array"]
$sString = "I am a string"

Call (_Test, $aArray)

Call (_Test, $sString)

Func _Test($vParam)

    If IsArray($vParam) Then
        _ArrayDisplay($vParam, "", Default, 8)
    Else
        MsgBox($MB_SYSTEMMODAL, "", $vParam)
    EndIf

EndFunc

M23

Edit: No count because you added that later

TheDcoder,

You mean like this example?

I think they mean something like this...

Local $aParams = ["String", 100]
Call(SomeFunc, $aParams)

Func SomeFunc($sString, $iNumber)
    ;  Code
EndFunc

 

[TheDcoder]

@Melba23 Nope, Like this:

Local $aParameters[4] = [0, "String", 1, 1.2, True]

Call("SomeFunc", $aParameters)

Func SomeFunc($sString, $iInteger, $fFloat, $bBoolen)
    ; Some code
    Return
EndFunc

Reread help for Call, especially Remarks.

[TheDcoder]

@guinness Its would be useful when an UDF wants to call another UDF (Register a function to call on an event)

@Melba23 Nope, Like this:

Local $aParameters[4] = [0, "String", 1, 1.2, True]

Call("SomeFunc", $aParameters)

Func SomeFunc($sString, $iInteger, $fFloat, $bBoolen)
    ; Some code
    Return
EndFunc

 

Code is wrong! It should be 5 not 4 and why do you have the count in the first element? Anyway @jchd is right, plus your suggestion would break call for those wanting to pass an array and not an array of params. I am rejecting your request.

[TheDcoder]

A special array can be passed in lieu of individual parameters. This array must have its first element set to "CallArgArray" and elements 1 - n will be passed as separate arguments to the function.

Ummm... Sorry

For arguments sake (pardon the pun) could you show me what you meant by this comment?

[TheDcoder]

_SomeUDF_SetCallbackOnSomeEvent("FunctionToBeCalled", $aParametersOfTheFunction)

instead of

_SomeUDF_SetCallbackOnSomeEvent("FunctionToBeCalled", "Parameter 1", "Parameter 2") ; Fixed number of parameters

@TheDcoder It's good to see enthusiasm, but it would make a lot more sense to learn what AutoIt features already do before making requests in Trac.  I think your suggestions are generally quite good though.

[TheDcoder]

Thanks

[guinness]

_SomeUDF_SetCallbackOnSomeEvent("FunctionToBeCalled", $aParametersOfTheFunction)

instead of

_SomeUDF_SetCallbackOnSomeEvent("FunctionToBeCalled", "Parameter 1", "Parameter 2") ; Fixed number of parameters

I understood that, but generally speaking it would be a bad idea to have dynamic params in UDFs.

[TheDcoder]

Dynamic no. of parameters because if the user of the "User Defined Functions" wants different pieces of information for his "defined function"

[guinness]

It has been a long day. So I am not really following you. Sorry. But glad this was solved.

[TheDcoder]

No problem

TheDcoder is this you are refering to:

local $ary[2] = ["1stparam","2ndparam"]

_CallAry("wordf",$ary)

Func _CallAry($func,$ary)
If IsArray($ary) Then
$param = ""
For $i = 0 To UBound($ary)-1
$ary[$i] = '"' &$ary[$i] &'"'
Next
For $i = 0 To UBound($ary)-1
   $param &=  $ary[$i] &","
Next
$param = StringTrimRight($param,1)
$str = 'Call ("' &$func &'",' &$param &')'
Execute ($str)
If @error Then Return (3,2,"Error in calling function")
Else
   Return SetError(2,5,"Not an array")
EndIf
EndFunc

func wordf($param1,$param2)
msgbox("","Showing parameters",$param1 &"-" &$param2)
endfunc

 

[TheDcoder]

@Surya It took me a while to understand the code, Its what I wanted

[Surya]

Glad i could help you TheDcoder. the whole array is split into parameters and given to the function requested,as the parameter function is converted to string i had to use the Execute() function .

[TheDcoder]

i had to use the Execute() function .
