Custom Query (3910 matches)

When a row in an arry contains a '|' dislaying of the line stops.

#include <Array.au3> dim $aaa [2]

$aaa [0] = "Ape|Nut|Mary|Wim" $aaa [1] = "Ape;Nut;Mary;Wim"

_ArrayDisplay($aaa)

If arrays are used with objects as e.g. properties some sort of memory leak occurs. This seems to be specific only to Array type. Example (monitor memory usage during execution):

$a = StringSplit("a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z", ",")

MsgBox(0, "", "start")
For $count = 0 To 10000
	$obj = ObjCreate("Scripting.Dictionary")
	$obj.add("test", $a)
	$obj = 0
Next
MsgBox(0, "", "stop")

For possible comparisons, VBS version would be:

a = Split("a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z", ",")
 
MsgBox("start")
For count = 0 to 10000
    Set obj=CreateObject("Scripting.Dictionary")
    obj.add "test", a
    Set obj = Nothing
Next
MsgBox("stop")

No leak there (or with some other languages).

Many many times I wished AutoIt had arrays with ranged size... there are numerous situations when I really don't use element0 from an array simply because I, as a human being, like to count starting from 1. Another thing is that there are some algorithms which can be optimized like in the example below:

Dim $counter[65..90]
For $i = 1 to StringLen($s)
  $counter[Asc(StringMid($s,$i,1))] += 1
Next

should be faster than

Dim $counter[26]
For $i = 1 to StringLen($s)
  $counter[Asc(StringMid($s,$i,1))-65] += 1
Next

because of the missing -65

The best part is that backward compatibility won't be ruined because arrays declared as "Dim $array[10]" will by default mean "Dim $array[0..9]" for the "compiler". This method of declaring arrays is found in user-friendly programming languages such as Pascal and Basic, whereas the old style is used in the middle level C programming language. Also, from what I can tell it shouldn't be to hard to implement, but... you know what's best!
