Hi All,

Kinda new to Lua and trying to sort aceDB tables with no success.

I have the following table definition:

    default_options = {
	global = {
		data = {
			-- Faction
			['*'] = {
				-- Realm
				['*'] = {
					-- Name
					['*'] = {
						class                      = "",   
					}
				}
			}
		},
	},
}
 

and am trying to do this:

function resortDB()
    print ("Starting Sort Action")
    local sfaction
    for faction, faction_table in pairs (self.db.global.data) do
	sfaction = faction
        for realm, realm_table in pairs (faction_table) do
		for pc in pairs (realm_table) do
	             table.sort(self.db.global.data[sfaction][realm], function(a,b)         
                          if self.db.profile.options.sort_type == "alpha" then
		              return a > b
	                  elseif self.db.profile.options.sort_type == "rev-alpha" then
                              return a < b 
	                  elseif ....

	                  end 
	             end )
		end
        end
    end
end

What I want to be able to do is sort the Characters. If i can get the alpha and reverse alpha to work i can then do a few other options.

Are you trying to sort a dictionary or a sequentially indexed table?

You cannot sort a Dictionary in Lua. Only indexed tables.

My data looks like:

["global"] = {
		["data"] = {
			["Horde"] = {
				["Silvermoon"] = {
					["Gurohir"] = {
						["class"] = "DEATHKNIGHT",
					},
					["Kerfinor"] = {
						["class"] = "ROGUE",
					},
					["Redridinhoof"] = {
						["class"] = "DRUID",
					},

This is an dictionnary, so you cannot sort it. At best you can fill another table to iterate over the names in the right order. E.g. :

local function revAlphaSort(a,b)
  return b < a
end

function addon:FetchOrderedNames(names, characters)
  wipe(names)
  for name in pairs(characters) do
    table.insert(names, name)
  end
  if self.db.profile.options.sort_type == "alpha" then
    table.sort(names)
  elseif self.db.profile.options.sort_type == "rev-alpha" then
    table.sort(names, revAlphaSort)
  end
end

-- To iterate through all faction/realm/names
local names = {}
for faction, realms in pairs(addon.db.global.data) do
  for realm, characters in pairs(realms) do
    addon:FetchOrderedNames(names, characters)
    for i, name in ipairs(names) do
      -- do whatever with name
    end
  end
end

PS: don't put anonymous function declaration in a loop: in Lua this will create as many function instances as times the loop gets executed.
