_ArrayUnique

[zalomalo]

By some chance i have seen and checked the functions _ArrayUnique wich use _ArrayInsert inside Array.au3.

I did one function some time ago for my needs to do the same but just in 1D, much more faster; its 6 lines long. Tell me if it could be interesting for someone/something and i could share it.

Did you check the beta version? As it's changed from the current stable.

[UEZ]

Just provide what you did and we can discuss whether it makes sense to update current function.

[zalomalo]

I dont want be ridiculoues or stupid, mine isnt a general purpose function, it just do it in a 1D array.

[guinness]

Well the issue with that is the current version supports 1d and 2d. But post as UEZ and who knows you might learn something?

Ok. I have splited in 3, to do it more versatile for share:

Local $aVectorNames=StringSplit(StringStripWS($sNames,3),$div)

Return($aVectorNames)
EndFunc ;==>__StringToArrayVars

Func __ArrayVarsToString(ByRef $aVectorNames,$div=',')
If Not IsArray($aVectorNames) Then Return($aVectorNames)
Local $sTempLista=''

   $sTempLista=(StringIsSpace($sTempLista))?($aVectorNames[$i]):($sTempLista&$div&$aVectorNames[$i])
Next
Return($sTempLista)
EndFunc ;==>__ArrayVarsToString

So you could:

Local $avKK=__StringToArrayVars(__ListUniqueElements(__ArrayVarsToString($avKK)))

Or:

$ExeToWait=StringSplit(__ListUniqueElements(__ArrayVarsToString($ExeToWait)&',kk.exe,shield.img,reporter64.exe'),',')

By the way, i did a function to get the 8.3 filename, exe's arguments, full path of exe and the exe with arguments, knowing the exe with a relative path and a root path; but i am not very happy with it. I tryed a bit with RegExps but i failed a bit. Could be somewhere related with this subject where i get some happy idea?.

PD: Im obssesed with optimize performance speed and memory size, because that i setup custom dedicated functions.

I'm surprised nobody responded to this. zalomalo - your implementation may be good for strings, but ArrayUnique() needs to also recognize data types. I'm not sure the current function does ATM: I'll have to dig into the code and take a look. Unfortunately your suggestion does not even preserve the data stored in an array.

It is not that what I expected according to the post title "_ArrayUnique" but I like the idea to make string with delimiter unique.

Imho, _StringUnique is more applicable.

Made some tests and it seems to work properly.

This might be useful!

[czardas]

Yes UEZ, I think it's a good idea.

[guinness]

I missed this. I don't really see the unique quality of this proposal (no pun intended). Maybe someone could provide usage of this and how it will benefit the mass market.

[czardas]

A delimited string unique function might be faster and use less resources than StringSplit() followed by _ArrayUnique() followed by _ArrayToString(). It needs testing.

[BrewManNH]

I think what guinness is asking is why would you need and/or want a string unique function? When would this ever be useful?

[czardas]

Half the posts in this topic are missing.

I assume guinness hacked the db to take back his Like vote.

[guinness]

No one has really answered my question from post #10, as most of the attention was turned to me suggesting the user should post in the Forum, which I never said. I meant I am not going to add this to the UDFs if it has not real benefit to the library.

[czardas]

I meant I am not going to add this to the UDFs if it has not real benefit to the library.

 

Of course not. It's more an idea for a string function which may have advantages in specific circumstances, providing it can be done optimally without necessarily accessing array functions. I wouldn't consider it important enough to add to any UDF, unless any visible advantages emerge from trying such an idea.

[guinness]

Thanks. Anyway if something comes out of this post a trac request, as I probably won't be following this topic anymore.
