_ArraySearch and _ArrayFindAll

Recommended Posts

wisem2540

_Arraysearch only seems to find the first instance of what I am searching for. Whereas _ArrayFindAll only returns the element numbers (but does find all of them)

is there a way to make _ArraySearch find more than 1 instance? Or make _ArrayFindAll return the actual values rather than the elements?

options for both below:

Local $array[5]=[1,1,1,3,4]
$iStart = 0
While True
 $value = _ArraySearch($array, 1, $iStart)
 If $value>=0 Then
  ConsoleWrite("array subscript=[" & $value & "] Value=" & $array[$value] & @CRLF)
 Else
  ExitLoop
 EndIf
 $iStart = $value + 1
WEnd
Local $array[5]=[1,1,1,3,4]
$aSub = _ArrayFindAll($array, 1)
For $i = 0 To UBound($aSub)-1
 ConsoleWrite("array subscript=[" & $aSub[$i] & "] Value=" & $array[$aSub[$i]] & @CRLF)
Next

The _ArrayFindAll option looks easier

#include <Array.au3>

Local $avArray[5] = [10, 11, 12, 11, 10]
Local $aiResult = _ArrayFindAll($avArray, "10")
_ArrayDisplay($avArray, "$avArray")

Dim $aiResult2[UBound($aiResult)][2]
For $i = 0 to UBound($aiResult)-1
  $aiResult2[$i][0] = $aiResult[$i]
  $aiResult2[$i][1] = $avArray[$aiResult[$i]]
Next
_ArrayDisplay($aiResult2, "Results of searching for 10 in $avArray")

mikell,

_arrayfindall runs _arraysearch in a loop. Since you going to have to process the results anyway why not cut out the middle man, like this...

#include <array.au3>

local $my_array[10] = ['a',0,'what','0',1,2,'2','1','what',1]

; example # 1 find all ocurrences of 2 and return as string
ConsoleWrite(__arrayfindall($my_array,'2') & @LF)

; example # 2 find all ocurrences of 'what' and return as array
local $aTmp = __arrayfindall($my_array,'what',0)
_arraydisplay($aTmp)


func __arrayfindall(byref $array,$srch,$ret_type = 1)

    ;  usage
    ;    $array    - array to search
    ;    $srch     - string to search for
    ;    $ret_type - 0 = return array, 1 = return a '|' delimited string

    local $tmp

    for $1 = 0 to ubound($array) - 1
        if $array[$1] == $srch Then $tmp &= $array[$1] & '|'
    next

    $tmp = stringtrimright($tmp,1)

    if $ret_type = 0 then
        return stringsplit($tmp,'|')
    Else
        return $tmp
    EndIf

endfunc

mikell,

What you are asking for does not seem terribly usefull so I expanded it a bit. The function will return one of the following:

1 - 2D array [0] = element #

[1] = value at element #

2 - string formated as element#-value|element#-value...

The function also supports "fuzzy" searching (parameter). If the search argument is contained anywhere in the element it will match.

Give it a whirl and see what you think...

#include <array.au3>

local $gennum = 50000, $aTestArray[$gennum], $StrLen = 5, $TestString

for $1 = 0 to $gennum - 1
    for $2 = 1 to $StrLen
        $aTestArray[$1] &= chr(random(65,90,1))
    Next
Next

local $st = timerinit()
local $aTmp = __arrayfindall($aTestArray,'Z',0,0)
ConsoleWrite(stringformat('!  Time to run %05i entries = %3.4f seconds for %4i matches',$gennum,timerdiff($st)/1000,ubound($aTmp)-1) & @LF)
_arraydisplay($aTmp)

func __arrayfindall(byref $array,$srch,$ret_type = 1,$fuzzy = 1)

    ;  usage
    ;    $array    - array to search
    ;    $srch     - string to search for
    ;    $ret_type - 0 = return 2D array of ele # and value
    ;                 1 = return a '|' delimited string of element#-value
    ;     $fuzzy    - 0 = find any ocurrence of string within the element
    ;               - 1 = element must strictly equal the string (default)

    local $tmp, $aTmp[ubound($array)][2],$ele = 0

    for $1 = 0 to ubound($array) - 1

        switch $fuzzy
            case 1
                if $array[$1] == $srch Then
                    $aTmp[$ele][0] = $1
                    $aTmp[$ele][1] = $array[$1]
                    $ele += 1
                endif
            case 0
                if stringregexp($array[$1],$srch) = 1 Then
                    $aTmp[$ele][0] = $1
                    $aTmp[$ele][1] = $array[$1]
                    $ele += 1
                endif
        endswitch

    next

    ; find # of hits

    local $row_cnt
    for $1 = 0 to ubound($aTmp) - 1
        if stringlen($aTmp[$1][0]) > 0  then ContinueLoop
        $row_cnt = $1
        ExitLoop
    next

    ; shrink array

    redim $aTmp[$row_cnt+1][2]

    if $ret_type = 0 then
        return $aTmp
    Else
        for $1 = 0 to ubound($aTmp) - 1
            $tmp &= $aTmp[$1][0] & '-' & $aTmp[$1][1] & '|'
        Next
        return stringtrimright($tmp,3)
    EndIf

endfunc

And just for the sake of completeness...

This function will return either a 2D array as

[0] - matching element number

[1] - matching element value (seems redundant)

or a string formatted as element#-element value|element#-element value....

and you can specify the kind of match as

0 - match if element contains the search argument

1 - match if element is equal to the search argument

2 - match if element starts with the search argument

3 - match if element ends with the argument

The example code searches an array of 5000 random length elements (1-200 chars) of capital letters for any elements containing the string "ZOO". The general search time is appx. .03 seconds.

#include <array.au3>

local $gennum = 5000
local $aTestArray[$gennum], $StrLen = 10, $TestString

for $1 = 0 to $gennum - 1
    for $2 = 1 to random(1,100,1)
        $aTestArray[$1] &= chr(random(65,90,1))
    Next
Next

local $st = timerinit()
local $aTmp = __arrayfindall($aTestArray,'ZOO',0,0)
ConsoleWrite(stringformat('!  Time to run %05i entries = %3.4f seconds for %4i matches',$gennum,timerdiff($st)/1000,ubound($aTmp)-1) & @LF)
_arraydisplay($aTmp)

ConsoleWrite(__arrayfindall($aTestArray,'ZOO',1,0) & @LF)


func __arrayfindall(byref $array,$srch,$ret_type = 1,$srch_type = 1)

    ;  usage
    ;    $array    - array to search
    ;    $srch     - string to search for
    ;    $ret_type - 0 = return 2D array of ele # and value
    ;               - 1 = return a '|' delimited string of element#-value (default)
    ;     $srch_type- 0 = find any ocurrence of string within the element
    ;               - 1 = element equals the string (default)
    ;               - 2 = element starts with search string
    ;               - 3 = element ends with search string

    local $tmp, $aTmp[ubound($array)][2],$ele = 0

    for $1 = 0 to ubound($array) - 1

        switch $srch_type
            case 1
                if $array[$1] == $srch Then
                    $aTmp[$ele][0] = $1
                    $aTmp[$ele][1] = $array[$1]
                    $ele += 1
                endif
            case 0
                if stringregexp($array[$1],$srch) = 1 Then
                    $aTmp[$ele][0] = $1
                    $aTmp[$ele][1] = $array[$1]
                    $ele += 1
                endif
            case 2
                if stringregexp($array[$1],'^' & $srch) = 1 Then
                    $aTmp[$ele][0] = $1
                    $aTmp[$ele][1] = $array[$1]
                    $ele += 1
                endif
            case 3
                if stringregexp($array[$1],$srch & '$') = 1 Then
                    $aTmp[$ele][0] = $1
                    $aTmp[$ele][1] = $array[$1]
                    $ele += 1
                endif
        endswitch

    next

    ; find # of hits

    local $row_cnt
    for $1 = 0 to ubound($aTmp) - 1
        if stringlen($aTmp[$1][0]) > 0  then ContinueLoop
        $row_cnt = $1
        ExitLoop
    next

    ; shrink array

    redim $aTmp[$row_cnt+1][2]

    if $ret_type = 0 then
        return $aTmp
    Else

            $tmp &= $aTmp[$1][0] & '-' & $aTmp[$1][1] & '|'
        Next
        return stringtrimright($tmp,3)
    EndIf

endfunc

What wisem2540 was asking for did not seem very useful indeed, that's why I didn't go further than playing a bit with the example from the helpfile

Of course your func is quite more efficient and helpful, so even if I didn't ask for it I will still store this in my own array-dedicated library

Nice work, thanks :)

mikell,

My mistake, apologies! I got this mental myopia thing going on...I hope you find it usefull.

edit: A note of caution...I don't flush the parms nor do I verify that the string delimiter does not participate in the result string.

No problemo :D

And please don't care about the error handling, I can do this ;)
