_ArrayToString() - AutoIt 3.3.14.2

[francoiste]

i have just upgraded from autoit 3.3.12.0 to 3.3.14.2 and noticed a difference in behaviour.

• with the previous version of autoit below code was working fine.
• with the new version it returns "-1"

repro code:

#include <Array.au3>

Local $aResult = _MyTest()
MsgBox(0, "Array Result", _ArrayToString($aResult, "; ", 1, 0))

Func _MyTest()
    Local $aTmp[1] = [0]

    _ArrayAdd($aTmp, "A")
    _ArrayAdd($aTmp, "B")
    $aTmp[0] = UBound($aTmp, $UBOUND_ROWS)

    Return $aTmp
EndFunc

it seems that for the "$iEnd_Row" parameter we now need to pass "-1" instead of previous "0".

the following snippet works fine:

MsgBox(0, "Array Result", _ArrayToString($aResult, "; ", 1, -1))

is that change on purpose?

Yes it is on purpose, the old method wouldn't allow you to only use from 0 to 0, which would be pointless but it was a bug. There is a script breaking changes list in the help file for new versions.

interesting.

however, when doing a search for "ArrayToString" in the "script breaking changes" section there are no hits ...?
even for the more general search on "Array" there is not a single hit.

But there is an entry for the Array UDF rewrite that points you to a list of changes that were made to that collection of functions.

[francoiste]

sorry, i still don't get it.

the section that you are referring to (Array UDF rewrite) is listed for "3.3.12.0".
but i have run into this issue only after upgrading from "3.3.12.0" to "3.3.14.2".

maybe the recent change is just missing from the "documenation"?
i can neither find any hint in the "script breaking changes" section nor in the general "history / changelog" listing.

to improve my code example:

this "$iEnd_Row" parameter is "optional" - and has an "internal default", anyways.

so to avoid running into such problems (when the internal defaults change in a future release): simply use the "Default" keyword:

; do NOT pass a default VALUE:
_ArrayToString($aResult, "; ", 1, -1))

; instead, use the "Default" KEYWORD:
_ArrayToString($aResult, "; ", 1, Default))

 

[BrewManNH]

Or don't use it at all if you're not altering it, or anything after it. It is optional after all.

[francoiste]

right.

i was sparing you from the full context.
in my code i have a two-dimensional array. that's why i can't omit that parameter.

_ArrayToString($aTmp, "; ", 1, Default, "; ", 2, 2)
