If $var check

Recommended Posts

AutID

Hello,

What does this simple code actually checks.

If $var Then

    ....

$var is set to False in a global scope and it changes depending on some other stuff to True or False.

So does the "If $var Then" checks if the variable is True?

Yes.

 

You can check this by using this example:

GLobal $var = False
_test()

$var = True
_test()

Func _test()
    If $var Then
        ConsoleWrite('is True' & @CRLF)
    Else
        ConsoleWrite('is False' & @CRLF)
    EndIf
EndFunc

Check it is true or if has some string. I mean

GLobal $var = "hola"
_test()

$var = ""
_test()

Func _test()
    If $var Then
        ConsoleWrite('Something' & @CRLF)
    Else
        ConsoleWrite('Nothing' & @CRLF)
    EndIf
EndFunc

Yes.

 

You can check this by using this example:

GLobal $var = False
_test()

$var = True
_test()

Func _test()
    If $var Then
        ConsoleWrite('is True' & @CRLF)
    Else
        ConsoleWrite('is False' & @CRLF)
    EndIf
EndFunc

 

I don't find this correct for a programming language.

So If Not $var will check the opposite of the value.

If $var = true or If $var = false seems better way to check for me. It is AutoIt after all ;)

Thank you.

I think mLipok's way for programming is Perfect. If $var is a bool variable only has two state true or false. if is not one else is another one.

Good for you.

A variable is not always a bool. It can be wathever. The If statment is that looks somehow wierd to me.

Anyway thank you both.

AutID,

Remember that AutoIt does not "type" its variables. Thus the following are considered "True":

True
"Any string"
Any number other then integer 0
while these are considered False:

False
"" ; An empty string
0  ; Integer 0
So the simple comparison "If $var Then" is perfectly valid syntax and will work without problem. :)

If also quicker to check if a variable contains text e.g.

Local $sString = "SomeString"
If $sString <> "" Then ; Kind of confusing and slightly slower...

; ...than

If $sString Then

....

Local $hTimer = 0, $sString = "Some String"

Sleep(1000)

$hTimer = TimerInit()
For $i = 1 To 10000
    If $sString Then $sString = $sString
Next
ConsoleWrite("1. " & TimerDiff($hTimer) & @CRLF)

$hTimer = TimerInit()
For $i = 1 To 10000
    If $sString <> "" Then $sString = $sString
Next
ConsoleWrite("2. " & TimerDiff($hTimer) & @CRLF)

$hTimer = TimerInit()
For $i = 1 To 10000
    If $sString Then $sString = $sString
Next
ConsoleWrite("1. " & TimerDiff($hTimer) & @CRLF)

$hTimer = TimerInit()
For $i = 1 To 10000
    If $sString <> "" Then $sString = $sString
Next
ConsoleWrite("2. " & TimerDiff($hTimer) & @CRLF)

$hTimer = TimerInit()
For $i = 1 To 10000
    If $sString Then $sString = $sString
Next
ConsoleWrite("1. " & TimerDiff($hTimer) & @CRLF)

$hTimer = TimerInit()
For $i = 1 To 10000
    If $sString <> "" Then $sString = $sString
Next
ConsoleWrite("2. " & TimerDiff($hTimer) & @CRLF)

It's slower because there is more things to parse, that's all :)

Obviously the OP doesn't know. It is hard to understand that compering it with one thing is faster than compering it with more than one. I guess i will achieve this level if someday i will become a dev.

Thanks for the clarifications, i will mark your answer as resolved.

 

Anyway thank you for the explanations everyone.

ConsoleWrite(NumberFormat(Ceiling(357846 / 1000)) & @LF)
Func NumberFormat($StringToFormat)
 Local $StringFormatted = ""
 Local $ArrayStringToFormat = StringSplit($StringToFormat, "")
 Local $counterForSeparator = 1
 For $i = $ArrayStringToFormat[0] To 1 Step -1
  If $counterForSeparator = 3 Then
   $StringFormatted = " " & $ArrayStringToFormat[$i] & $StringFormatted
   $counterForSeparator = 0
  Else
   $StringFormatted = $ArrayStringToFormat[$i] & $StringFormatted
  EndIf
  $counterForSeparator += 1
 Next
 Return StringStripWS($StringFormatted, 1)
EndFunc
by misstyping this line "If $counterForSeparator Then" i came accross with this question.

Good to know, however i don't find it correct.
