I wrote TStoreData.lua class for simple save data to standard lua format, which is simple to read back to script (described here: HowTo using LUA script as data file)

 

Example: Save Data

 

require ("class/TStoreData")

test_data =
{
   pos = {0,1,2},
   name = "player1",
   other =
		{
			items = {"item1","item2","item3"},
			subitems = {"A","B"},
			data = {
				x = 0,
				y = 1,
				z= 2},
			tree = {
					 leaf1 = "l1",
					 leaf2 = "2",
					 leaf3 =
					 {
						leaf31 = "31",
						leaf32 = "32"},
					  used = true
					}
		}
}

DataSaver = TStoreData:New()

-- save uncompressed data
DataSaver:Save("result.lua",false,test_data)

-- save compressed data
-- DataSaver:Save("result.lua",true,test_data)

 

Output:

return
{
["other"] = 
{
	["items"] = 
	{
		[1] = "item1";
		[2] = "item2";
		[3] = "item3";
	};
	["subitems"] = 
	{
		[1] = "A";
		[2] = "B";
	};
	["data"] = 
	{
		["y"] = 1;
		["x"] = 0;
		["z"] = 2;
	};
	["tree"] = 
	{
		["used"] = true;
		["leaf3"] = 
		{
			["leaf32"] = "32";
			["leaf31"] = "31";
		};
		["leaf1"] = "l1";
		["leaf2"] = "2";
	};
};
["name"] = "player1";
["pos"] = 
{
	[1] = 0;
	[2] = 1;
	[3] = 2;
};
}

 

Example#1: Load Data

 

GameData = dofile("result.lua")

print(GameData.pos[1],GameData.pos[2],GameData.pos[3])
print(GameData.name)
print(GameData.other.items[1])
print(GameData.other.items[2])
print(GameData.other.items[3])

 

Example#2: Load Data

 

require ("class/TStoreData")

LoadData = TStoreData:New()
GameData = LoadData:Load("result.lua")

print(GameData.pos[1],GameData.pos[2],GameData.pos[3])
print(GameData.name)
print(GameData.other.items[1])
print(GameData.other.items[2])
print(GameData.other.items[3])

 

Note: Saved format looks little bit different, but this saved format is only other lua syntax. Work same like before.
