local patch = {

local err = jpatch.apply(obj,patch)
if err then

end

-- possible to compress size of patches
local c_patch , err = jpatch.compress(patch)
if not err then
    print(json.encode(c_patch))
end

local d_patch , err = jpatch.decompress(c_patch)
if not err then
    print(json.encode(d_patch))
end
