Here is the simple system I use for managing default settings in my addons:
In MyAddon.toc:
Code:
## SavedVariables: MyAddonDB
In MyAddon.lua:
Code:
-- This function gets run when the PLAYER_LOGIN event fires:
function MyAddonDB:PLAYER_LOGIN()
-- This table defines the addon's default settings:
local defaults = {
x = 0,
y = 200,
p = "BOTTOM",
font = {
face = "Friz Quadrata TT",
size = 14,
outline = "OUTLINE",
},
color = {
r = 0,
g = 1,
b = 1,
}
}
-- This function copies values from one table into another:
local function copyDefaults(src, dst)
-- If no source (defaults) is specified, return an empty table:
if type(src) ~= "table" then return {} end
-- If no target (saved variable) is specified, create a new table:
if type(dst) then dst = {} end
-- Loop through the source (defaults):
for k, v in pairs(src) do
-- If the value is a sub-table:
if type(v) == "table" then
-- Recursively call the function:
dst[k] = copyDefaults(v, dst[k])
-- Or if the default value type doesn't match the existing value type:
elseif type(v) ~= type(dst[k]) then
-- Overwrite the existing value with the default one:
dst[k] = v
end
end
-- Return the destination table:
return dst
end
-- Copy the values from the defaults table into the saved variables table
-- if it exists, and assign the result to the saved variable:
MyAddonDB = copyDefaults(defaults, MyAddonDB)
end
|
How would you use these defaults in your addon would it be
MyAddonDB.x ?
of would this function replace your:
Code:
local cfg = MyAddonDB.defaults
MyFrame = CreateFrame("frame")
MyFrame:SetPoint(cfg.p, UIParent, cfg.x, cfg.y)
The reason I ask is I would like to get away from Ace for some of the addons im working on and if this will alow me to have a defaults like ace does then the only othe part Ill have to figure out is in-game config to change things without doing a /reload.
Thanks Coke
