Avoid declaring Global Variables Inside functions by declaring Static Variables instead

[V for Vendetta]

This is an example showing how to make the "Main Script" to get "Static Variables" values from functions, avoiding so declaring "Global" variables inside functions!

Test Function Example:

Code: Select all

loop, 10
Test( )

msgbox, % Test("Addition") "`n`n" Test("Test") "`n`n" Test("Auto") "`n`n" Test("Code") "`n`n" Test("Lol")

msgbox, % Addition "`n`n" Test "`n`n" Auto "`n`n" Code "`n`n" Lol	;these variables from the main script are all blank


Test("", "Avoid using Global Variables Inside functions.txt")	;read ".ini" files directly from the function
					;"Error" output if no file found


msgbox, % Test("Addition") "`n`n" Test("Test") "`n`n" Test("Auto") "`n`n" Test("Code") "`n`n" Test("Lol")

msgbox, % Addition "`n`n" Test "`n`n" Auto "`n`n" Code "`n`n" Lol	;these variables from the main script are all blank



Test(GetStaticVarValue := "", Load := "")	;___________ Test (Function) ____________
{
static Addition, Test, Auto, Code, Lol

	if Load !=		;if "Load" is not blank
	{
	Iniread, Addition, %Load%, section, Addition
	Iniread, Test, %Load%, section, Test
	Iniread, Auto, %Load%, section, Auto
	Iniread, Code, %Load%, section, Code
	Iniread, Lol, %Load%, section, Lol
	return
	}

	if GetStaticVarValue !=		;if "GetStaticVarValue" is not blank
	{
	GetStaticVarValue := %GetStaticVarValue%
	return, GetStaticVarValue
	}

Addition++
Test = Alot of test
Auto = no manual
Code = Script
Lol = not funny
}

Test "Load" File:

Code: Select all

[section]
Addition = 200
Test = 201
Auto = 202
Code = 203
Lol = 204

To use global variable inside a function, you have to declare it as global in the function (or declare it as a super-global outside of it). Otherwise you are just using local variables that happen to have the same names as your global variables. See the documentation on global variables inside functions.

Btw, this thread should be in the Ask For Help forum, not in Scripts and Functions.

This isn't a "Question"!

This is an example showing how to make the "Main Script" to get "Static Variables" values from functions, avoiding so declaring "Global" variables inside functions!

Before you edited it, it was not a "how to" example. You had a script in which you incorrectly expected the variables to act as global simply because they had the same name both inside and outside the function, and you didn't understand why.

Your function basically boils down to this:

Code: Select all

Test(GetStaticVarValue := "")
{
	static Addition, Test, Auto, Code, Lol
	Addition++
	Test = Alot of test
	Auto = no manual
	Code = Script
	Lol = not funny
	return, %GetStaticVarValue%
}

Which is a trivial example demonstrating what "static" does. It is not a function that is likely to be used by others which is generally what is posted in Scripts and Functions.

It could possibly go in Tutorials but its rudimentary nature gives the impression that you need help understanding how super-global, global, local, and static variables work.

yes, it is and always was a "how to" example!

The Script is the same, I didn't modify anything, so, you are the one who didn't understand it at all!

I have the impression that you are the one here who needs help understanding how super-global, global, local, and static variables work.

Your function basically boils down to this:

Code: Select all

Test(GetStaticVarValue := "")
{
	static Addition, Test, Auto, Code, Lol
	Addition++
	Test = Alot of test
	Auto = no manual
	Code = Script
	Lol = not funny
	return, %GetStaticVarValue%
}

What is this? what is this non-sense? It is not even possible to get functions "Static Variables" values from "Main Script" as you are demonstrating in that function of yours!

As of today, you edited your original post three times, the latest being earlier today (a month after you originally posted it). It was originally showing that the value of a variable wasn't what you said it should have been, and the reason was that there was nothing tying the values of variables inside a function to those outside of it, other than the names were the same (which doesn't do that, and it seems you may have learned that since and are revising history). A moderator should have access to your original unedited post, although I'm not interested in pursuing it any further. It is pretty clear you have become (or have always been) a forum troll, and I will be ignoring your threads and posts from now on.

[V for Vendetta]

I am a troll ...!

off course you are a troll, and a liar too!

The "original unedited post" will confirm that you are a little liar!

I just edited the title and add this This is an example showing how to make the "Main Script" to get "Static Variables" values from functions, avoiding so declaring "Global" variables inside functions! to the main thread! Nothing more!

Thanks to whoever moved this thread here, though I think it's not a Tutorial, just an "Useful" Script!

[just me]

As you've been told before, your originally post did not contain something which could be considered as an 'useful script'. Just LOL and join a LOL-Community. You'll be the "Pro" you want to be, there.

Also:

off course you are a troll, and a liar too!

You just got your first warning.

My first warning of what?

he said I edited the script, but I didn't, so it's a lie, he's lying, so he's a liar!

[just me]

Think!

It's obvious an "Useful" Script!

You are the one who should join a "LOL-Community"! You are a "Pro" making people Laughing Out Loud!

LolLolLolLolLolLolLolLolLolLolLolLolLolLolLolLolLolLol...!

[nnnik]

If you would be so kind as to add more text then everyone would be happy.
As it is now nobody understands that much anyways.

[tank]

he said I edited the script, but I didn't, so it's a lie, he's lying, so he's a liar!

Please review the terms of this board

You agree that “AutoHotkey Community” have the right to remove, edit, move or close any topic at any time should we see fit.

the folks you are calling liars at least a few are moderators of this board nearly its entire lifetime. I have found them rarely on the wrong side of a point tho it does happen. had it not been for the log of your edits i might have been inclined to go with you here. but then you called them liars and forget that all activity on this board is in fact logged.

I am happy to back someone if they are right against other moderators, but your clearly just trying to
You had your laugh now be done with it.

the folks? please ... the one person, to be objective ...!

Please don't make me Laugh!

Yesterday I was searching for different ways to make the "Main Script" get "Static Variables" values from functions, and I just happen to find this "Thread" of mine in the "Help" section! The 3 thread (not script) editions was made yesterday!

I edited the "thread" not the "Script"! The "original unedited post" can prove this! But anyway, if you believe me or not, it's not my problem, it's your problem!

but your clearly just trying to

Haha, you really make me , my friend! LolLolLolLolLolLolLolLolLol...!
