#678 closed Bug (No Bug)

MAX_LINESIZE confine arrays

Reported by: dutCh Owned by:
Milestone: Component: AutoIt
Version: Severity: Blocking
Keywords: MAX_LINESIZE arrays Cc:


Please remove this unneeded restriction. I want dim arrays with size much bigger than 4KB.

dim $aDlg[100][8] = [[...], _
  [...], _

This hole thing can only be 4KB!!

We have found a workaround with diming several arrays <4KB and an for-loop in the code. But thats not very cool and imho unneeded.

Why not take the problem at the root and enhance the parsing:

Dim $aArr[][] = [[ ],

A define of a 2-dim array, equal sign, 2 open brackets, stuff, one close, an comma... you realize that an dim that array - with no size limit. Thats not an error - stupid user forgot to close the braces - only an multi-dim array!!?

And why not do a heck of a job and kick this "_" too? I'm in an array dim. I have an closed bracked, a comma, KICK ALL WHITESPACE, and await and got the next open bracket. Thats simple, isn't it?

AutoIt should make the things easier. And cooler!

What do you think?

However, thanx for that great tool. Is much of fun for me!!

AutoIt is line based. The line limit is 4096 characters per line. There is no plan to change this.

Replying to Valik:

Okay, AutoIt is line based. Otherwise you would need something like a preprocessor. Understandable.

But why this ridiculous limit of 4KB? A PC today has one million times more RAM, not to count virtual memory!??

You define a constant for the size of a single code line. For some reason you don't like dynamic memory management. Okay. It's a design decision.

Take this into account, here comes an easy solution: Supply a factor!

Let the constant MAX_LINESIZE = 4096 be the default. Factor 1. And give another constant for free extensibility! :-)

#define ENOUGH_RAM_FOR_ALL = 1 ;default

Who needs can adjust this.

No design changes are required. Easy to implement. Kicked the main limit of AutoIt!

Welcome in the world of gigabyte ram!

Wow, thanks. Now fuck off and stop using this language. Clearly you consider us complete idiots incapable of even the most basic thought.

Here's a thought? Don't write your code like that. That's not the only way to create an array, you know? Or is it more convenient to bitch about problems and then insult our intelligence by implying we don't have enough knowledge to know how to not use magic numbers in our code.

Sorry. No offense meant. I'm not a native English speaker. Please be indulgent with me.

Maybe its about you master the complicated part, make a huge, impressive work. And this easy little detail - there is no way.

I want only point out a constraint in AI and thats seems to me that there are no logical reason therefor.

Please show me another cool way to populate my array.

Uncool are:

  • I supply an extra file, open it, read it, parse it

and too:

  • I must give a Dim befor every single array line

Currently i define multiple arrays <4KB and use a for loop to process them one after another.

Thank you.

And let me state again: AutoIt is a cool tool!

Please show me another cool way to populate my array.

#include <Array.au3>

Local $a[1][2]

ArrayData_PushBack($a, 0, "abc", "def")
ArrayData_PushBack($a, 1, "ghi", "jkl")


Func ArrayData_PushBack(ByRef $a, $nIndex, $data1, $data2)
		Local $nSize = UBound($a)
		If $nIndex >= $nSize Then
			ReDim $a[($nSize + 1) * 1.5][UBound($a, 2)]
			$nSize = UBound($a)
	Until $nSize > $nIndex
	$a[$nIndex][0] = $data1
	$a[$nIndex][1] = $data2

There are other more clever things you can do to make the code even better.

Thank you. You're right. There's more than one way to skin a cat!

PS: Is that really an english idiom. In Germany we say "Viele Wege führen nach Rom. - Many ways lead to Rome."

Where the hell did the cat came from? Alf? ;-)
