Help to declare and assign many variables

13 posts in this topic

#1 ·  Posted (edited)

I need to declare a lot of variables as global and assign them later inside a function.

I can do this with a variable already declared as global:

$variable01 = "a123"

But not this:

$variable01 = "a123", $variable02 = "r123", $variable03 = "z456", $variable04 = "a789"

It's very uncomfortable -to manage and aesthetically- to declare them one by one, each in one line. Is there any posibility to do ten in a line or something like that?

I can't do the assignment of variables at the same time as declaration (yes, appending Global before the previous example works as expected), has to be in other place inside a function.

Sorry if this is a silly question but I haven't found anything in the FAQ, the best coding practices or help file.

I personally prefer to declare and assign variables one line at a time, in autoit, but to each their own

Global $vVar1 = "1234", $vVar2 = "2345", $vVar3 = "3456", $vVar4 = "4567", $vVar5 = "5678", $vVar6 = "6789", _
        $vVar7 = "7890", $vVar8 = "890", $vVar9 = "90"

I assume you mean something like this:

Global $variable01, $variable02, $variable03, $variable04
Func _Variables()
    Dim $variable01 = "a123", $variable02 = "r123", $variable03 = "z456", $variable04 = "a789"
EndFunc

I wish I could do that but has to be separated.

Yes, it will reuse the global definition but isn't the Dim keyword a not recommended one or something?

Its not recommended when declaring new variables, the variable should already be declared as either Local or Global before using Dim similar to how ReDim is used.

You could use an array. Perhaps something like this.

Global $aVar[4] ; use a global array as a container
Global Enum $00 = 0, $01, $02, $03 ; can be omitted because ...
; special variable names are not necessarily needed

AssignElements() ; fill the array

; test the result
ConsoleWrite($aVar[$00] & @CRLF & $aVar[$01] & @CRLF & $aVar[$02] & @CRLF & $aVar[$03] & @CRLF)

Func AssignElements()
    $aVar = StringSplit( _
    'a123|r123|z456|a789' _ ; this data could also be replaced by a variable
    , '|', 2)
EndFunc

Bresacon,

You asked:

 Is there any posibility to do ten in a line or something like that?

And then when shown that this was indeed possible:

Global $vVar1 = "1234", $vVar2 = "2345", $vVar3 = "3456", $vVar4 = "4567", $vVar5 = "5678", $vVar6 = "6789", _
        $vVar7 = "7890", $vVar8 = "890", $vVar9 = "90"

say that:

So what exactly do you want?

czardas,

Light dawns - thanks. Although I still fail to see why only assigning one variable per line is difficult "to manage and aesthetically" - just put those lines inside a region and shrink it when not required:

Global $variable01, $variable02, $variable03, $variable04

Func _Assign_Values()
    ; Other code
    #Region
    $variable01 = "a123"
    $variable02 = "r123"
    $variable03 = "z456"
    $variable04 = "a789"
    #EndRegion
    ; Other code
EndFunc

Yep, I agree that it's best to keep things straight forward and simple. I personally prefer to avoid using numerous global variables in my code.

Testing Subz's Dim example of post #3, to my surprise, it works.    And the help file explains why it works.

Global $variable01, $variable02, $variable03, $variable04

_Variables()
ConsoleWrite($variable01 & "   " & $variable02 & "   " & $variable03 & "  " & $variable04 & @CRLF)


Func _Variables()
    ; Dim = If the variable name already exist globally, it reuses the global variable - from AutoIt help.
    Dim $variable01 = "a123", $variable02 = "r123", $variable03 = "z456", $variable04 = "a789"
EndFunc   ;==>_Variables

#cs Returns :-
a123   r123   z456  a789
#ce

That's the confirmation I needed.

Thanks everybody. This forum is superb. ;)

I'll try that. Looks very tidy.

I didn't know that trick, but I don't use SciTe. Laugh all you want, I always used the Notepad2 mod variant, am very comfortable in there. And lately I've been trying RJ TextEd -I like this one very much- and SublimeText.
