Examples

local json = require "json"

local t = { ["item1"] = "value1", ["pi"] = 3.1415,
    ["name2"] = { 1, false, true, 23.54, "a \021 string" },
}

print( "t: " .. json.prettify( t ) )
--> t: {
-->   "item1":"value1",
-->   "name2":[1,false,true,23.54,"a \u0015 string"],
-->   "pi":3.1415
--> }

local line = display.newLine( 200, 90, 227, 165 )

print("line._properties: " .. json.prettify( line._properties ) )
