Copying Saved Variables

[circonian]

I'm trying to create savable profiles for all of my addons settings. I've gotten everything to work, with one small problem. The table changes when I reload the UI. It might be easiest if I just explain what I did.

A user pushes a button which runs some code & I attempted to copy the saved variable table into another table so it could be reloaded later.

I tried to create a copy of the table using (spoiler is code used to copy the table):

Warning: Spoiler

function JunkIt.deepcopy(orig)
    local orig_type = type(orig)
    local copy
    if orig_type == 'table' then
        copy = {}
        for orig_key, orig_value in next, orig, nil do
            copy[JunkIt.deepcopy(orig_key)] = JunkIt.deepcopy(orig_value)
        end
        setmetatable(copy, JunkIt.deepcopy(getmetatable(orig)))
    else -- number, string, boolean, etc
        copy = orig
    end
    return copy
end

and I used the following code to save the profile:

local tSavedVars = JunkIt.deepcopy(JunkIt.SavedVariables)
table.insert(JunkIt.AccountSavedVariables["PROFILES"]["PROFILE"], {_sProfileName, tSavedVars})

That created a copy and it worked just fine, until I reloaded the UI.

Heres what the tables (saved profiles) look like before & after I reload the UI.
Profile 2 on the left shows what it looks like after I create a new profile, before I reload the UI.
Profile 1 on the right shows what it looks like after I reload the UI.


Before reloading the UI I could reload all of the saved variables by doing:

for k,v in pairs(JunkIt.AccountSavedVariables["PROFILES"]["PROFILE"]) do
      if v[1] == _sProfileName then
            JunkIt.SavedVariables = v[2]
      end
end

EDIT:

So I figured out the table is not adding an extra ["default"] level. Duh that is my default saved variables table. The problem is that everything else is disappearing when I reload the UI. Everything that has that (m) in front of it. I'm assuming that has something to do with metamethods & metatables, which I don't really understand very well. Does this have something to do with it?.

I found another post suggesting to use ZO_DeepTableCopy:

local tSavedVars = ZO_DeepTableCopy(JunkIt.SavedVariables)
table.insert(JunkIt.AccountSavedVariables["PROFILES"]["PROFILE"], {_sProfileName, tSavedVars})

But ZO_DeepTableCopy doesn't copy metatables. That only copied the ["default"] table and GetInterfaceForCharacter() function. It did not copy the current settings, see picture below:



Is there an easier way to accomplish what I'm trying to do?

I'm answering my own question in case anyone else is interested, I managed to figure out how to get this to work.

Code to backup/save settings into a table:

local sDisplayName = GetDisplayName()
local sUnitName = GetUnitName("player")
    
local tSavedVars = ZO_DeepTableCopy(_G["AddonSavedVarsName"]["Default"][sDisplayName][sUnitName])

Code to restore/load settings from table back into saved vars:

local sDisplayName = GetDisplayName()
local sUnitName = GetUnitName("player")
 
ZO_DeepTableCopy(tBackupSettingsTable, _G["AddonSavedVarsName"]["Default"][sDisplayName][sUnitName])

Where AddonSavedVarsName is the name you gave your saved variables in your Addon.txt file:

## SavedVariables: JunkItSavedVars

ZO_DeepTableCopy does not copy metatables, but I was apparently copying the wrong table before. The table were copying now (in the above code) does not contain metatables so we can use ZO_DeepTableCopy. It can be used as:

tDestination = ZO_DeepTableCopy(tSource)
-- or 
ZO_DeepTableCopy(tSource, tDestination)
