After patch is applied then it can be tested with application and run with command `LUA_PATH="/usr/ports/Mk/LuaScripts/?.lua;;" /usr/libexec/flua /usr/ports/Mk/LuaScripts/example.lua`:
```
local Logging = require("logging")
local logger = Logging.new(nil, "INFO", true)
logger:log(logger.INFO, "This is INFO level and should be printed")
logger:setLevel(logger.WARN)
logger:info("This is INFO level and should not be printed")
logger:warn("This is WARN level and should be printed")
logger:error("This is ERROR level and should be printed")
local table = { a = 1, b = 2 }
logger:debug(table)
logger:info("val1='%s', val2=%d", "string value", 1234)
```
