ConsoleWrite

4 posts in this topic

Just wondering if this is a bug.

Local $a1[2] = [1,2]
Local $a2[2] = [1,2]

$cw = ConsoleWrite($a1 & @CRLF & $a2 & @CRLF & "some text" & @CRLF)
ConsoleWrite("error and return = " & @error & " " & $cw & @LF)

Output..

>Running:(3.3.12.0)blah...
--> Press Ctrl+Alt+F5 to Restart or Ctrl+Break to Stop
error and return = 0 0
+>20:59:36 AutoIt3.exe ended.rc:0
>Exit code: 0    Time: 0.536

I understand an array might not have a value to display, there are other values in the expression that do.

Compared to this, makes me believe it to be some sort of bug.

Local $a1[2] = [1,2]
Local $a2[3] = [1,2,3]

$cw = ConsoleWrite(null & @CRLF & $a2 & @CRLF & "some text" & @CRLF)
ConsoleWrite("error and return = " & @error & " " & $cw & @LF)

JohnOne,

This very thing was discussed a few months ago amongst the MVPs and there was a sharp difference of opinion between those who believe that as arrays have no String return it is quite reasonable that ConsoleWrite should fail when asked to concatenate one with a string, and those who felt that the array should just be counted as an empty string and the remainder of the parameters displayed.

This was the code I posted to show what happens:

#include <array.au3>

Global $a[1] = ["Test1"], $s = "Test2"

; Attempt to concatenate array and string - you get an array
Local $x = $a & " / " & $s & " end" & @CRLF
; This CW fails completely as the argument is not a string
ConsoleWrite($x & " - " & VarGetType($x) & @CRLF)
; But the array remains untouched - you can see the array type remains
_ArrayDisplay($x, VarGetType($x))

; Reversing the order of concatenation gives a string and just ignores the array
Local $y = $s & " / " & $a & " end" & @CRLF
ConsoleWrite($y & VarGetType($y) & @CRLF)
The discussion ended without a firm decision being taken as to what should be the "correct" result - and as one who supported the first of the options I outlined above I am quite happy to retain the status quo. ;)

In the example above, $a2 does appear to be treated as an empty string, consolewrite only fails when an array is first to be parsed.

That's what made me believe it to be a bug.

Local $a1[2] = [1,2]
Local $a2[3] = [1,2,3]
Local $a3[4] = [1,2,3,4]
Local $anythingelse

$cw = ConsoleWrite($a1 & @CRLF & $a2 & @CRLF & $a3 & @CRLF & "some text" & @CRLF)
ConsoleWrite("error and return = " & @error & " " & $cw & @LF)

$cw = ConsoleWrite($anythingelse & $a1 & @CRLF & $a2 & @CRLF & $a3 & @CRLF & "some text" & @CRLF)
ConsoleWrite("error and return = " & @error & " " & $cw & @LF)
