more variables in a single line autoit possible?

[butterfly]

is there a way to change more variables on a single line when an if statement is met?

as example:

Global XYOptionWidth = 3
If $XYOptionWidth = 3 Then $SelectedWidth = 1600 and  $troll = 89 , $autoitforum = "I Love you all"

any possible way to make it look as clean as written above?

ps* i know above example does not work

Not in a single line probably not, you'd have to enclose it in a multiline If statement.

If $XYOptionWidth = 3 Then 
    $SelectedWidth = 1600
    $troll = 89 
    $autoitforum = "I Love you all"
EndIf

I wouldn't say no because someone may come along with some totally unwieldy code that allows you to do it. But the way I wrote it is much easier to troubleshoot and debug if something was to be wrong in it.

If your variables are not already declared, maybe you can use.

If $XYOptionWidth = 3 Then Local $SelectedWidth = 1600, $troll = 89, $autoitforum = "I Love you all"

This seems to be clean and understandable ?

jguinch,

Personally I would still go for an If...EndIF structure:

If $XYOptionWidth = 3 Then
    Local $SelectedWidth = 1600, $troll = 89, $autoitforum = "I Love you all"
EndIf

I have never understood why anyone would want to cram everything onto one line at the expense of readability. Given the relative slowness of AutoIt, any tiny increase in time required to run a multi-line If...EndIf compared to a single line version is in my opinion well worth the increase in readability.

The one-liner is possible

Global $SelectedWidth = 0 ,$troll = 0 , $autoitforum = "nul", $XYOptionWidth = 3
Msgbox(0,"", $SelectedWidth &@crlf& $troll &@crlf& $autoitforum)

If $XYOptionWidth = 3 Then Execute( Assign("SelectedWidth" , "1600") and Assign("troll", "89") and Assign("autoitforum", "I Love you all") )

Msgbox(0,"", $SelectedWidth &@crlf& $troll &@crlf& $autoitforum)

Though personally I would never use something like this

I'm one of those it's old habit from the 80's, programming on computers with 16KB, 48KB and 64KB of RAM, everything was crammed into as little as possible. So we are used to it, and having just as hard a time with a gazilion lines, as you have with reading crammed code.

Werty,

I too started coding in that era (on a 1k RAM ZX-81) - but that did not stop me adopting more reasonable habits when the chance presented itself. As a young child I was also brought up in a house with no bathroom and an outside toilet - but I much preferred indoor plumbing when we moved to a new home.

Ahh, yes, problem is I didnt go to the bathroom for 20 years (well, more like 15 years, as in doing something else than programming)

But anyways, you DO understand it anyway now

Not at the expense of readability (smaller regions, overall perspective, navigation and sometimes conformity). The field of view is limited by both the width and height of your screen.

[czardas]

If your variables are not already declared, maybe you can use.

If $XYOptionWidth = 3 Then Local $SelectedWidth = 1600, $troll = 89, $autoitforum = "I Love you all"

Unless this has changed recently, variables can be redeclared in AutoIt. On a side note: it's generally not advisable to declare variables based upon a condition.

I agree with you all, but I just ask to the OP question. 

Obviously, I do not use this type of variable declaration, except for the Guinness's challenges

 

Czardas, has you said, variables can be redeclared in AutoIt : yes but i think it is a bad habit, no ?

It makes little sense to redeclare a variable in most cases I can think of. If the variable already exists, why declare it again when all you have to do is change its value? However redeclaration can be used as a quick method to empty a large array.

@czardas You can just assign the value of the array to 0

$avData = 0

[czardas]

@czardas You can just assign the value of the array to 0

$avData = 0

 

Not if you just want to delete the array's contents (to free memory) while still leaving the array intact - ready to be used again.

Re-dim it to 1 element, set the first one to "", and resize it to the original size after?

I see where you're going, and it would be easier to just redeclare it - but would it be considered a "good coding practice"?

[czardas]

It was documented at one time (variables can be redeclared), I guess it still is. ReDim is best avoided due to its latency. I haven't made a speed comparison, but other than that I agree that redeclaration of an array for this reason may be a dubious thing to do. I mentioned it as being plausible. I imagine the fastest method would be to have an empty array template that you can assign to the old array.

The helpfile says : "Declaring the same variable name again will erase all array values and reset the dimensions to the new definition."

As this is not mentioned as "not recommended" let's assume that such a way is correct
