Log Setter

This is a module to set the logging level.

  • Instead of building a class the whole module is used to access the variables and functions within it.
  • By default this module uses the package name with .log appended to it as the name of the log-file name.


To make it portable this module uses introspection to get the name of the package. This means that it should be at the top-level of the package so that modules in sub-folders can use it.

log_setter : set_logger(args)
log_setter : cleanup()


set_logger(args) Creates a logger and sets the level based on args.
cleanup([log_directory, log_name]) Saves the last log to log-directory


Since the log-filename is set in this module a cleanup function is put here to be accessible outside of the main flow of the system (to allow it to be called even in the event of a crash).

  • A sub-directory is created (default is “last_log”)
  • The log is moved to the sub-directory

This function was implemented so the log does not continue to grow even as the code is re-run, but there is at least one copy of the log backed-up.

Example use:


Setting the Logger

This is the main function to use. It is intended to be used by the ArgumentParser to create sub-commands so it expects a namespace with command-line arguments as attributes. The logging-level is set according to the following:

Setting the Log-Level
debug silent LogLevel
False False Info
False True Error
True False Debug
True True Debug
