Sorting a 2D array by version

[TheDcoder]

Hi, I have a 2D array with 2 columns, the 1st column contains a "version string" and the 2nd column contains a generic string. I want to sort it in the descending order so the latest version comes first.

#include <Array.au3>

Local $aVersionsAndReleases[4][2] = [["0.2.8.9", "Release #1"], ["0.2.9.10", "Release #3"], ["0.2.9.11", "Release #4"], ["0.2.8.10", "Release #2"]]

_ArraySort($aVersionsAndReleases, 1)
ConsoleWrite(_ArrayToString($aVersionsAndReleases, ' - '))
_ArrayDisplay($aVersionsAndReleases)

Unfortunately, _ArraySort isn't working here . This is the output generated by the script:

0.2.9.11 - Release #4
0.2.9.10 - Release #3
0.2.8.9 - Release #1
0.2.8.10 - Release #2

The expected result should be:

0.2.9.11 - Release #4
0.2.9.10 - Release #3
0.2.8.10 - Release #2
0.2.8.9 - Release #1

I am looking to develop an function which does this... but I don't know where to start . Can someone help me get started? Thanks in Advance!

I've written a sorting function for user defined sorting (see the UDF in attachment) .
With this the solution should be something like this:

#include "DynArray.au3"

Local $aVersionsAndReleases[4][2] = [["0.2.8.9", "Release #1"], ["0.2.9.10", "Release #3"], ["0.2.9.11", "Release #4"], ["0.2.8.10", "Release #2"]]

_ArraySortFlexible($aVersionsAndReleases, _MyCompare)
_ArrayDisplay($aVersionsAndReleases)


; user defined comparison function for user-defined sorting
Func _MyCompare(ByRef $A, ByRef $B)
    Local Static $h_DLL_Shlwapi = DllOpen("Shlwapi.dll")

    Return -DllCall($h_DLL_Shlwapi, "int", "StrCmpLogicalW", "wstr", $A[0], "wstr", $B[0])[0]
EndFunc   ;==>_MyCompare

Edit: removed attached Dynarray.au3 because functions are now part of ArrayPlus-UDF.

shorter comparison function

[czardas]

Search for 'natural sort' algorithms. You'll find something.

[Jos]

Here is an option with some good old fashioned programming logic:

#include <Array.au3>

Local $aVersionsAndReleases[4][2] = [["0.2.8.9", "Release #1"], ["0.2.9.10", "Release #3"], ["0.2.9.11", "Release #4"], ["0.2.8.10", "Release #2"]]

ReDim $aVersionsAndReleases[4][3]
For $x = 0 To UBound($aVersionsAndReleases) - 1
    $Version = StringSplit($aVersionsAndReleases[$x][0], ".")
    For $y = 1 To $Version[0]
        $aVersionsAndReleases[$x][2] &= StringRight("000000" & $Version[$y], 6)
    Next
Next
_ArraySort($aVersionsAndReleases, 1, 0, 0, 2)
ConsoleWrite(_ArrayToString($aVersionsAndReleases, ' - '))
_ArrayDisplay($aVersionsAndReleases)

@czardas I have looked into natural sort but most of them only talk about a single number... not multiple digits in a single column! I will look into them anyway. Now I know what natural sort is .

@Jos That's quick hack you have got there! . Never thought that it would be that simple

@AspirinJunkie Your UDF looks very promising, I will give it a go .

I will post back with the results which I finish playing around with the solutions. Thanks for post y'all! Much Appreciated!

In the end, I decided to go with @wraithdu's _ArrayNaturalSort. Just what I needed!

[czardas]

Natural sort is more flexible however, for a bespoke situation such as this, it could be considered overkill. I tend to strip away things I don't need once everything is working, so I quite often use a standard function with all the bells and whistles attached before making final adjustments. This approach can sometimes be useful when you are unsure of all the features you intend to implement: eventually you might want to keep the whistles and get rid of the bells. I don't think there is a right or wrong approach to this and the methods above are all valid.

Well said @czardas .

[Malkey]

This method converts a[.b[.c[.d]]]] to 00a[00b[00c[00d]]]] (Where abcd are digits.) by executing a string from a StringRegExpReplace function.

It works on a 1D or 2D array.

#include <Array.au3>

Local $aVersionsAndReleases[6][2] = [["0.2.8.9", "Release #2"], ["0.2.9.10", "Release #1"], ["0.2.8", "Release #1"], _
                                     ["0.2.7.10", "Release #1"], ["0.2.9.11", "Release #2"], ["0.3", "Release #1"]]
; Or try
;Local $aVersionsAndReleases[6] = ["0.2.8.9", "0.2.9.10", "0.2.8", "0.2.7.10", "0.2.9.11", "0.3"] ; 1D array

_ArrayColInsert($aVersionsAndReleases, 0) ; Add a new column, Col 0.
For $x = 0 To UBound($aVersionsAndReleases) - 1
    $aVersionsAndReleases[$x][0] = Execute(StringTrimRight(StringRegExpReplace($aVersionsAndReleases[$x][1], "(\d+)\.?", _
              'StringRight("000${1}", 3) & '), 3)) ; Converts a[.b[.c[.d]]]] to 00a[00b[00c[00d]]]] Where abcd are digits.
    ;ConsoleWrite(StringRegExpReplace($aVersionsAndReleases[$x][1], "(\d+)\.?", 'StringRight("000${1}", 3) & ') & @CRLF)
Next
_ArraySort($aVersionsAndReleases, 1, 0, 0, 0)
ConsoleWrite(_ArrayToString($aVersionsAndReleases, ' - '))
_ArrayColDelete($aVersionsAndReleases, 0, True) ; Now delete the added column.
_ArrayDisplay($aVersionsAndReleases)

More RegEx magic. Thanks for the code @Malkey

[iamtheky]

edit: super late as per usual

I ended up with the Jos/Malkey answer as well, but with no want to fix the formatting after altered.

#include <Array.au3>

Local $aVersionsAndReleases[4][2] = [["0.2.8.9", "Release #1"], ["0.2.9.10", "Release #3"], ["0.2.9.11", "Release #4"], ["0.2.8.10", "Release #2"]]

for $i = 0 to ubound($aVersionsAndReleases) - 1
    $aSplit = stringsplit($aVersionsAndReleases[$i][0] , "." , 2)
    $aSplit[ubound($aSplit) - 1] = StringFormat("%02i" , $aSplit[ubound($aSplit) - 1])
    $aVersionsAndReleases[$i][0] = _ArrayToString($aSplit , ".")

I needed a solution which fixes the version string after the sorting because those version numbers are displayed to the user and I do not want the user get confused! Albeit, it is a nice way if you want to sort the array internally

[iamtheky]

nah, its probably slower than the regexp if you are going to send it through formatting a second time.  

I havent seen a good race thread in a while, version sort could stand to go through the wringer.

I had a similar case here :

using the regexp provided on post # 7 of that topic, here's another shot:

#include <array.au3>
Local $aVersionsAndReleases[][] = [["0.2.8.9", "Release #1"],["0.2.9.10", "Release #3"],["0.2.9.11", "Release #4"],["0.2.8.10", "Release #2"],["0.3", "Release #5"]]
;
For $i = 0 To UBound($aVersionsAndReleases) - 1
    $aVersionsAndReleases[$i][0] = StringRegExpReplace($aVersionsAndReleases[$i][0], '(?<!\d)(\d)(?!\d)', '0\1')
Next
;
_ArraySort($aVersionsAndReleases, 1, 0, 0, 0)
_ArrayDisplay($aVersionsAndReleases)

RegEx for the rescue again, thanks for sharing the code

try with this values:

Local $aVersionsAndReleases[4][2] = [["0.2.8.9", "Release #1"], ["0.2.9.1", "Release #3"], ["0.2.9.11", "Release #4"], ["0.2.8.10", "Release #2"]]

 

[iamtheky]

my bad, somehow removed the type 2s (to remove the ubound count) from my stringsplits

#include <Array.au3>

Local $aVersionsAndReleases[4][2] = [["0.2.8.9", "Release #1"], ["0.2.9.1", "Release #3"], ["0.2.9.11", "Release #4"], ["0.2.8.10", "Release #2"]]

_ArraySort($aVersionsAndReleases, 1)

for $i = 1 to ubound($aVersionsAndReleases) - 1


If StringSplit($aVersionsAndReleases[$i][0] , "." , 2)[0] = StringSplit($aVersionsAndReleases[$i - 1][0] , "." , 2)[0] AND StringSplit($aVersionsAndReleases[$i][0] , "." , 2)[1] = StringSplit($aVersionsAndReleases[$i - 1][0] , "." , 2)[1] AND StringSplit($aVersionsAndReleases[$i][0] , "." , 2)[2] = StringSplit($aVersionsAndReleases[$i - 1][0] , "." , 2)[2] AND execute(StringReplace($aVersionsAndReleases[$i][0] , "." , "+")) > execute(StringReplace($aVersionsAndReleases[$i - 1][0] , "." , "+")) Then _ArraySwap($aVersionsAndReleases , $i , $i - 1)


next

_ArrayDisplay($aVersionsAndReleases)

Try with this array in your example of post #19.

Local $aVersionsAndReleases[4][2] = [["0.2.9.4", "Release #1"], ["0.2.9.21", "Release #4"], ["0.2.9.11", "Release #3"], ["0.2.9.5", "Release #2"]]
