logcontrol 0.0.2

A logger manager for Python programs

logcontrol: A logger manager for Python programs

It provides:

• Centralized control of log level (per-group)

• Logging for exceptions and excessive runtime

Original use case:

• Python GUI program containing many packages and modules

• Each source file that logs creates a proper logger for use within that file * e.g. logger = logging.getLogger(__name__)

  • This allows a good logging hierarchy for control at a central point

• I wanted to simplify enabling debug level for specific packages or groups

Installation:

• pip install logcontrol

  (Tested for Python >=3.6.5 on Linux (Ubuntu) and Windows 7/10)

Usage:

• example (where otherpackage and anotherpackage are example names):

  # imports of fictitious packages
  import otherpackage
  import anotherpackage
  
  # import logging for easy access to log levels
  import logging
  import logcontrol
  
  # Register loggers you wish to control.
  # You can have user-friendly names for the groups if you wish:
  logcontrol.register_logger(otherpackage.logger, group='Other Package')
  
  # Set output file for the root logger:
  logcontrol.set_log_file('main_log.txt')
  
  # Enable specific log levels per-group:
  logcontrol.set_level(logging.DEBUG, group='Other Package')
  
  # Make specific groups log to console while debugging:
  logcontrol.log_to_console(group='Other Package')
  
  # You can even disable or enable propagation per-group:
  logcontrol.disable_propagation(group='Other Package')
  logcontrol.enable_propagation(group='Other Package')
  
  # Loggers added to the same group will get the same configuration.
  # This would automatically set DEBUG level and attach the console logging handler:
  logcontrol.register_logger(anotherpackage.module.logger, group='Other Package')
  
  # You can get a dict of group names with level names (good for populating a debug/log control popup):
  logcontrol.group_level_names()
