-- Basic tables

-- Main API table

-- Table for modpol data

-- Record of every state change should appear here

-- Locate framework top-level directory.

-- This function is intended for use under Linux and/or UNIX only.  

-- It
-- returns  a relative or  absolute path  for the framework  top-level
-- directory without a trailing slash.

-- if your application has a different method of getting the script directory, 
-- then feel free to overwrite this in an init.lua or other such file by first
-- defining the modpol table and then defining the get_script_dir() function

local get_script_dir = modpol.get_script_dir or function() 
    local  str = debug.getinfo (2, "S").source:sub (2)
           str = str:match ("(.*/)") or "."
           str = str:gsub ("/$", "", 1)
    return str
end

-- Absolute or relative path to script directory.
local  topdir = get_script_dir()
modpol.topdir = topdir
print (topdir)

-- Persistent storage
-- must implement modpol.load_storage() and modpol.store_data()


-- Select a storage method
-- -- preferably, declare this in the init.lua that calls modpol.lua  This is the default.
-- Works with CLI:
modpol.storage_file_path = modpol.storage_file_path or topdir .. "/storage/storage-local.lua"
-- Works with Minetest 5:
--modpol.storage_file_path = modpol.storage_file_path or topdir .. "/storage/storage-mod_storage.lua")

--execute the storage file
dofile (modpol.storage_file_path)


-- If available, load persistent storage into active tables
modpol.load_storage()

-- Final checks

-- create instance if not present
