I need convert integer to string and vice versa...

[Trigger.edge]

Hello guys I need to convert an integer to a string, but not the I2S method.... eg: IntegerToString (4356464646) = "My integer string" / StringToInteger ("My integer string") = 4356464646

I'm not sure how to achieve it, can someone help me?

If i understand you correctly, you could do that using the return bug.
But it seems it has never gone, right ?

Oh yeah, strings are constant in Warcraft, that could work.

strings aren't constant and may heavily vary between 2 users unless specific conditions applied
theres no 100% safe way, so dont bother

Are strings not kept in a singelton string table, and always kept there? That's what I remember anyway.

This might help.

Base 256 is pretty useless as a generic approach, you can't pass 4 characters.

Also, didn't Blizzard.j already have those functions?

You might just use a hashtable, then store the string in the hashtable with the hash key of the string as key.
Then you can revert the hashing by looking in the hashtable for its entry.
However, the string to int has to be called first in every single case.

4 characters might be enough for this case.
You might even increase it by using a lower base... yea, only to 5 or 6 characters.

Perhaps, but as usual with people asking questions on forums, OP didn't bother giving any kind of requirements or goals, so who knows.

Well no matter what base you use, you're always bound to a collision (Pigeonhole principle) because from what I understand from OP's post, any string length should work. Better start reading how to make a proper hashing algorithm then.

StringHash are case-insensitive though. But if that's ok to the OP, this is probably the best way.

Accessing memory from the script - it's time of the revolution

So, using the function SH2I and I2SH of the library TypeCast should do the job.

Btw, there is not only the not case sensitive behavior with StringHash.

StringHash("a//b) == StringHash("a\b") or StringHash("a/b") == StringHash("a\\b"), can't remember.

 

[DracoL1ch]

you can't rely all clients have the same strings base, its a gamble

 

[Troll-Brain]

Sure, they won't have exactly the same internal string table if they don't have the same language of wc3 and/or there are strings defined in a local block.
Any clue about other cases ?
But i still don't really know what Trigger.edge want to do.

Talking about StringHash, wasn't it there that someone showed how the function does work, in C or whatever else ?

Nope!

I think this could work, but I do not have the concentration needed to write it, however I will try...

if you don't mind the overhead.. i use this snippet for hashes that MUST be unique. (was constructed as a byproduct of a discussion on using objects as hashtable keys and that same collision issue..)

i mostly use it for stuff like player names(cant control them thus eventually some will collide.... i got a function that does name to pid lookup) also i have a command system in the map and i use a hashtable to look up the command handlers so those names better not collide..

library StringHashEx requires Table

globals
private constant integer REHASH = 1222483
private key tbKey
private Table t = tbKey //allowed due to the way Table works
endglobals

function StringHashEx takes string key returns integer
local integer sh = StringHash(key)
loop
if not t.string.has(sh) then
set t.string[sh] = key
exitwhen true
endif
exitwhen t.string[sh] == key
set sh = sh + REHASH
endloop
return sh
endfunction

endlibrary
