Copying the name of a variable?

[haybail]

How do you name a variable the name of another variable so to copy it down? On the script.

Say I have one of these:

crazies = { ["one"] = 500, ["two"] = 5000, ["three"] = 50000 } 

or this:

crazies = [10] = 5, [4] = 2, [1] = .5 } 

or even this:

local x,y,z, = getElementPosition ( theElement) 
crazies = { [x], [y], [z] } 

Not sure if you can do that but anyway.

And I want to call the variable and write it down as its name in the crazies. How do I do that?

for k,v in pairs(crazies) do 
        ( the name of the variable in crazies ) = theValue 
end 
outputChatBox ( one ) 

outputChatBox ( 10 ) 

outputChatBox ( x ) 

I tried tostring().

Also tried to do the same thing, but I failed too. I think it's not possible.

I don't think I know what you're trying to do. If you name a "cell" of table it's not located at index, that is if your table looks like:

table[ "one" ], table[ "two" ]... table[ 1 ] does not exist in the table unless you made it. So, for example:

local tab = { a = 1, b = 10 } 
for k, v in pairs( tab ) do 
    print( k, type( k ) ) 
end 
-- this will print: 
-- a    string 
-- b    string 

As you can see a and b are strings.

In the 3rd example you can do this:

crazies = { getElementPosition( theElement ) }

I think he means the first thing. That was what I wanted to find out too. Thanks!

So it will print the string out to chatbox? Pretend its:

# local tab = { apple = 1, banana = 10 } 

It will print apple, banana?

I'm trying to extract the variable from the table and take it in its simplest form so for example:

table = { for = true, fabalaba = 10 } 

Would be table[for] and table[fabalaba]. I'm trying to get it to be for and fabalaba with the same values by extracting it and making the new variables from the table. Can I do that with print? Maybe:

print( k, type( k ) ) = v or tostring(v)

You can simply:

local tab = { apple = 1, banana = 10 } 
print( tab.apple ) -- this will print 1 to server console 
print( tab.banana ) -- and this will print 10 
  
tab.banana = 11 -- let's change value of banana in table 
print( tab.banana ) -- now it will print 11

But I want to extract the variable so I can do this:

print( apple ) 

Another example would be like this, but this is sloppy:

# local tab = { apple = 1, banana = 10 } 
  
function takeFruit ( ) 
        for a,e in pairs ( tab ) 
                if a = apple then 
                        apple = e 
                elseif a = banana then 
                        banana = e 
                end 
        end 
end 

Maybe not sloppy but not how I would like to do it. If I could get the name of the variable I could do this:

for a,e in pairs ( tab ) 
        a = e -- ( apple = 1 ) 
end

I think I finally know what you're trying to do now. LOL

You could do something like this:

tab = { apple = 1, banana = 10 } 
for k, v in pairs( tab ) do 
    loadstring( tostring( k ) .." = " .. tostring( v ) )( ) 
end 
--[[ after this loop, you will have variables with names of "cells" from the tab 
     so you can use the names as variables, like: ]] 
print( apple ) 
print( banana ) 

If you have some MTA elements or tables in the tab, you can use similar method:

tab = { apple = 1, banana = 10 } 
for k, v in pairs( tab ) do 
    loadstring( tostring( k ) .." = tab.".. tostring( k ) )( ) 
end 
print( apple ) 
print( banana )

Might be more efficient to do:

  
tab = { apple = 1, banana = 10 } 
  
for k, v in pairs( tab ) do 
    _G[k] = v 
end 
  
print(apple) 
print(banana)

Yes I think that's it! Thank you both.
