Array Sorting

5 posts in this topic

I have a list of groups with contexts appended like so:

c_group.spo.cairns.qd

a_group.spo.cairns.qd

n_group.spo.cairns.qd

v1_group.inc.spo.cairns.qd

aa_group.inc.spo.cairns.qd

za_group.nda.mackay.qd

gb_group.nda.mackay.qd

aa_group.nda.mackay.qd

ab_group.inc.nda.mackay.qd

The group name is the first part before the first full stop eg. first one is c_group

The context is everything after the first full stop eg. first one is spo.cairns.qd

I need to sort the list so everything is grouped first alphabetically by context and then, within each of these groupings, alphabetically by the group name.

If I reverse everything then do a sort it sorts by context nicely, then reverse again to get list sorted by context. But then how to sort by group name inside that?

Any help greatly appreciated.

You need a function that sorts on multiple columns. Search the Example Scripts forum and you will find something like

Thanks for the tip water. I ended up getting my act together and writing it myself.

#include 
#include 

$string = ClipGet()

$array = StringSplit($string,@CRLF,1)

;reverse contents of each element in array
for $x = 1 to $array[0]
  $array[$x] = _StringReverse($array[$x])
Next

;sort array with reversed contents to sort by context
_ArraySort($array)

;reverse elements back to original condition
for $x = 1 to $array[0]
  $array[$x] = _StringReverse($array[$x])
Next


$a = 1 ;starting element for sort of a context
$b = 0 ;ending point for a sort of a context

while $a < $array[0] ;step through all elements of array from 1
  $match = StringRegExp($array[$a],".*?\.(?i)(.*?QD)",1) ;context to match
  for $x = $a to $array[0]
    $thismatch = StringRegExp($array[$x],".*?\.(?i)(.*?QD)",1) ;context of this element
    if $thismatch[0] = $match[0] Then ;if contexts match
      $b = $x ;set end point of sort to this element
    endif
  Next
  _ArraySort($array,0,$a,$b) ;sort elements with the same context
  $a = $b + 1 ;set start element for next search
WEnd

_ArrayDisplay($array,"Two level sorted")

The regular exp<b></b>ressi&#111;n was a bit of a pain. The only way I could get it to work was to specify the last part of the context.

Any advice on the regex appreciated :)

There are a number of examples of 2D arrays sort over multiple columns as a simple forum search shows.

It's a shame that we can use neither Assign nor Execute to build up a 2D array directly, else we could do that (doesn't work of course):

#include <Array.au3>

$string =    "c_group.spo.cairns.qd" & @CRLF & _
            "a_group.spo.cairns.qd" & @CRLF & _
            "n_group.spo.cairns.qd" & @CRLF & _
            "v1_group.inc.spo.cairns.qd" & @CRLF & _
            "aa_group.inc.spo.cairns.qd" & @CRLF & _
            "za_group.nda.mackay.qd" & @CRLF & _
            "gb_group.nda.mackay.qd" & @CRLF & _
            "aa_group.nda.mackay.qd" & @CRLF & _
            "ab_group.inc.nda.mackay.qd"
StringReplace($string, ".qd", "")
Local $count = @extended
Assign('array[' & $count & '][2]', StringTrimRight("[" & StringRegExpReplace($string & @CRLF, "(?is)(.*?)_group\.(.*?)(\R)", "[""$2"", ""$1""],"), 1) & "]", 1)
ConsoleWrite(@error & @TAB & VarGetType($array) & @LF)   ; no error reported but wrong type assigned
_ArrayDisplay($array)      ; nope!

Hence we need to do the work by ourselves:

#include <Array.au3>

;~ $string = ClipGet()
Local $string =    "c_group.spo.cairns.qd" & @CRLF & _
                "a_group.spo.cairns.qd" & @CRLF & _
                "n_group.spo.cairns.qd" & @CRLF & _
                "v1_group.inc.spo.cairns.qd" & @CRLF & _
                "aa_group.inc.spo.cairns.qd" & @CRLF & _
                "za_group.nda.mackay.qd" & @CRLF & _
                "gb_group.nda.mackay.qd" & @CRLF & _
                "aa_group.nda.mackay.qd" & @CRLF & _
                "ab_group.inc.nda.mackay.qd"
StringReplace($string, ".qd", "")
Local $count = @extended
Local $aValues = StringRegExp($string & @CRLF, "(?im)([^\.]+)\.(.*)\R", 3)
_ArrayDisplay($aValues)        ; for demo purpose

Local $array[$count][2]
For $i = 0 To $count - 1
    $array[$i][0] = $aValues[2 * $i + 1]    ; context
    $array[$i][1] = $aValues[2 * $i]        ; group name
Next
_ArrayDisplay($array)        ; for demo purpose

; now proceed to sort $array on column 1 then column 2 with some multi-column sort UDF
