Free Plugin : Memory Plugin

[Sakuya]

Hi AMSWaves
By accident i discovered that it is possible to use the memory plugin in an easy way.
Sample code:

Memory.TblTest={"Bananas","Apples"}
Dialog.Message(type(Memory.TblTest),Table.Concat(M emory.TblTest, ";", 1, TABLE_ALL))
-- returns a normal concated string "Bananas;Apples"

Memory.TblTest=nil
Dialog.Message("",type(Memory.TblTest))
-- returns "nil"

I find this way to use the Memory plugin very useful (and easy), but before I go on with testing the question is:
is the allocated memory actually freed by setting the used variabel to 'nil'.?

I hope you will find the time for an answer, thanks in advance.

You can do that with anything..

Application.ExampleTable = {"stuff", "more stuff", "even more stuff"};
Dialog.Message("Example", "Entries in table: "..#Application.ExampleTable);

Application.ExampleTable = nil;
collectgarbage(); -- forcefully invoke garbage collection to free memory.
Dialog.Message("Example", "Type: "..type(Application.ExampleTable));

Thank you.

NO, the memory address will no longer be available to the application but it will still exists in the systems memory (this is called a *Memory Leak*)

you need to free the allocated memory buffer before setting the variable to nil to avoid leaks

EDIT:

huh?, in your code, you are not allocating memory, you are simply using a lua table ??

I am just declaring a lua-table, e.g. Memory.MyTable={} or a Memory.StringVar="Something" and it works.
Maybe the plugin itself has a lua-table structure whitch handles the different functions, and makes this possible?

But the question is still if there will be a memory leak, if not its an easy way to handle variabels for use in dialogex and so on

Thanks for your reply.

I've looked through these threads on the AutoIt plug, but seem to be the only one having this issue.

When i run AutoIt_Example.am7 and compile it, i get On Preload, Line 40:attempt to call field 'OpenLibrary' (a nil value)

I haven't changed the default layout of the accompaning files, anybody have an idea? (i'm running AMS7.5, Windows 7 Ult x64)
