BUG - case sensitivity in AA.Delete() - solved, ParseJson()

Archived
1

I have a function that sets a new associative array (AA) value:
m.cAA.puz[ 1].teleTrap = 1 ’ Store puz info

Later I wanted to delete it, so I ran:
? m.cAA.puz[ 1].Delete(“teleTrap”) ’ Reset to default where key/value doesn’t exist, potentially cuts down on save game size

But it wasn’t working - which is why I added the ?, and it always prints “false” - why???

Then I tried:
? m.cAA.puz[ 1].Delete(“teletrap”) ’ Reset to default where key/value doesn’t exist, potentially cuts down on save game size

WORKS!

Turns out when I assigned the value, it was assigned as “teletrap” all lower case, and when I go to use .Delete(), it’s case sensitive! This seems like a bug to me. I don’t care if it saves the key string all lower case even though I entered some caps, but I wanna have my cake and eat it too - allow the delete command to not care if I enter caps there too!

What happens when you call setmodecasesensitive

Are you calling SetModeCaseSensitive on the AA? If you don’t call that, it should work the way you want:


BrightScript Debugger> a={}       
BrightScript Debugger> a.teleTrap = 1
BrightScript Debugger> ?a.Delete("teleTrap")
true

No, I’ve never called SetModeCaseSensitive in my life! :sunglasses:

When I try your test in debugger it works just like you show it working for you.

So something must be different…testing…

AHA! I found the answer! :grinning_face_with_smiling_eyes:

I was also testing my saving and loading using registry info. I do that via FormatJson() and ParseJson(), so I just reviewed them and see “Any roAssociativeArray objects in the returned objects will be case sensitive”. So that explains it! :wink:

I suppose it’s not a bug then, just something to be aware of.

Yep, it’s a feature necessitated by JSON being case-sensitive itself. If regular case-insensitive AAs were returned, that will risk “folding” multiple elements into one, like say for “{a: 97, A: 65}”. So the parser creates all its AAs case-sensitive

Got it. I have no experience with Json (not a programmer), but that makes sense.

BTW, I was ECSTATIC to discover FormatJson() and ParseJson(), makes my life 100 times easier than saving and loading a zillion bits of data into individual registry entries! :sunglasses:
