booleans and Scripting.Dictionary objects

[Gabriel13]

While debugging my JSON library, I've run into a situation where working with a Scripting.Dictionary object results in my boolean values being changed into numbers.

func testDictionary($a)
    local $d=objCreate('Scripting.Dictionary')
    for $i=0 to ubound($a)-1
        $d.add($i,$a[$i])
    next
    return $d
endfunc

local $aTest[2]=[false,true]

msgbox(0,default,$aTest[0]) ; displays false
msgbox(0,default,$aTest[1]) ; displays true

local $ignore=testDictionary($aTest)

msgbox(0,default,$aTest[0]) ; now displays 0 instead of false
msgbox(0,default,$aTest[1]) ; now displays 1 instead of true

Apparently, by just referencing the boolean values in the $d.add() call, they're converted into numbers within my array.

The only way I've found to avoid this problem is to make sure I have an immutable reference to my variables – in this case, by changing the top line to:

func testDictionary(const byRef $a)

I think, it's not a problem because AutoIt treats 0 even like FALSE and 1 like TRUE.

It's a bit surprising that a COM object can mutate my variable types just by "looking" at them like this. This was nowhere on my radar screen when looking for bugs, and introduces another potential set of unexpected side-effects to watch out for.

Also, when dealing with JSON data, the distinction between "0" and "false" can indeed be significant.

That being said, I'm sure your explanation covers why this particular scenario may have gone unnoticed until now.

It's nice seeing Skroob is still alive after crashing on the "Planet of the Apes"

(I wonder how the apes got internet though )
