So, firstly it seems like an excellent library - as you’d expect from DMC 
I’m having a few troubles trying to retrieve data however, and hope somebody who’s using it might be able to help.
I initiate the structure in main.lua like so:
[lua]
local function initializeAutoStore()
– check here to see if we’ve already initialized the data structure
–
if not AutoStore.is_new_file then return end
--== new data file, initialize the data structure ==–
– get a reference to the root of the data structure
– right now ‘data’ is an empty, “magic” table, eg {}
local data = AutoStore.data
– add empty container to the tree in which to store our UFO objects
data[‘powerups’] = {}
– add some data to our new tree
data.powerups[‘1’] = { name=“A”, id=1, quantity=0 }
data.powerups[‘2’] = { name=“B”, id=2, quantity=0 }
data.powerups[‘3’] = { name=“C”, id=3, quantity=0 }
data.powerups[‘4’] = { name=“D”, id=4, quantity=0 }
data.powerups[‘5’] = { name=“E”, id=5, quantity=0 }
data.powerups[‘6’] = { name=“F”, id=6, quantity=0 }
– save some app specific info
– perhaps our data version, eg, in case the structure needs to change in the future
– or a secret key, etc
--data[‘app_info’] = { data_version=‘1.0’, secret={ id=“124”, key=“F5@E$sj1” } }
– Yes, all of those changes will be automatically saved
– and there’s no “.save()” in sight !
end
function main()
initializeAutoStore()
end
[/lua]
In a later file I’m trying to retrieve it:
[lua]
local AutoStore = require( “dmc_autostore” )
local classPowerUp = {}
local classPowerUp_metatable = {__index=classPowerUp}
function classPowerUp.new()
local powerUps = AutoStore.data.powerups
local data = powerUps[‘1’]
print(“STOP”)
end
return classPowerUp
[/lua]
However there is never the data in either powerUps or data. I’ve stepped through the library and noticed a few things:
a) the JSON file is being created properly and storing the data accurately.
b- it seems to be passing nil in the addPixieDust() function. Even though I can find my data nestled deep within the structure, proxy is always being returned as nil and so this
[lua]
self.data = addPixieDust( json.decode( content ) )
[/lua]
Always comes back empty. I’ve noticed the library makes extensive use of metatables, so perhaps this is being stored in different tables - but I just can’t seem to access it. I guess I’m doing something stupid in my initialisation or attempts to retrieve the data - hoping somebody can point this out.
Many thanks,
