Variable Length & Generate Variables On-The-Fly

[Enternal]

Does it state anywhere the maximum length a variable can be? Approximately 32,000? I want an exact number if possible.

The reason is that I realized that my Selection Store script will have issue if someone decides to add thousands of files to it and if the names are really long, the script would probably break since it won't be able to deal with the length of the variable. So that comes to my next question and is it possible to generate variables on the fly? Like automatically generating a new variable with base $Variable_# and the # will automatically increment?

[Enternal]

Hmm... okay. So maybe my fear is unfounded. I was pretty sure XYplorer had an issue before when the variable was too long but right now... it's at 180,419 double bytes character and is still working as expected. Going to stress it some more and see if it ever crash haha.

135.561.197 seems to be the magic number, unfortunately.
But this is not a generic number: readfile() stucks around 60-70 MB files, afaicr, for instance, leaving you with the impression that it's a variable storage limit. Not good for log management.

$a = strrepeat("0", "135561198"); writefile ("test.txt", "$a"); beep; echo done; // error on v13.80.0128

$a = strrepeat("0", "135561197"); writefile ("test.txt", "$a"); beep; echo done; // last valid value

Hm, confirmed, interesting number, does not ring a bell. I'll check this later.

Hmm... interesting! On the other hand, I just decided for the lolz used StrRepeat("0", "100000000000"); and that worked!

If I count it right you're over 32 bit

(OK: XY should have noticed? ?)

Code: Select all

StrRepeat("0", "100000000000");

throws error 6 (overflow) here.

Lol. It was working before... I don't know but now it's throwing an overflow error just like Don said. On the other hand, strrepeat("0", "135561197") now gave me "out of string place" and stopped working like before. It's weird!

EDIT: It's now working again.

On the other hand, I think 13 million characters should be enough room. At that range, I highly doubt anyone is going to run into it without causing XYplorer to slow down like crazy. Besides, even after trying to add many many files to the variable, I only went up to around 280,000. I guess in general, we're fine then. But this is still an interesting experiment. I'm sure Don even had some fun here right?

It's 135 million characters

Fine!

Oh. Reading it wrong. Ok 135 is MOOOORE than enough.

Two replies are also more than enough.

The problem overflowed on him so he's overflowing himself, now.
