This came about because I wanted to have dynamic variables created in a function accessible in other areas without making the func global. I wanted to avoid creating many unnecessary global vars that might be used only once. I also didn't want to bother clearing all those vars to free up resources. On the other hand, I could declare all vars except the desired global ones local, but I'm too lazy to declare each var used, and some are dynamic themselves. It also can help to avoid creating many unique var names. For my purposes, this takes care of a fairly common issue.
Also, I thought that this might help with combining several scripts. I'm not sure how it could be implemented yet. It'll take some testing to see how useful it will be, if at all.
Code:
;Convert a dynamic local variable to a global variable
;EXAMPLE: In this case the result is like: g_1_localvar, g_2_localvar, Etc
_var = g
function(_var)
loop,4 ;this happens with vars in a global scope
{ tmp := _var "_" A_Index "_localvar"
tmp1 .= tmp " - " %tmp% " but now it's a global variable!`n"
}
msgbox,%tmp1%
Return
function(_num)
{
loop,4 ;this all happens with vars local to this func
{ %_num%_%A_Index%_localvar = This used to be a local variable,
globalWrapper(_num "_" A_Index "_localvar", %_num%_%A_Index%_localvar)
}
}
globalWrapper(victim, content) ;this turns a dynamic local variable into a global variable
{
global
%victim% := content
}
Of course, this example is more complex than it needs to be, but I think that it displays the concept well.
