setup(

Usage

Import this module, set logging output, optionally set logging level, set a script level variable pointing to this modules log variable, then issue log.debug() etc.

You only need to set the output destination and logging level once, so if you have multiple files in your project, set the output destination and the logging level in the first one. In all the others just point a script level variable to ccalogging.log.

When using a log file, if the file already exists, new log messages are appended to it.

The default logging level is WARNING.

# first (or only) project file

import ccalogging          # import the module

ccalogging.setConsoleOut() # set global logging destination
ccalogging.setDebug()      # set global log level
log = ccalogging.log       # point a script-level variable to the logger

log.info("Logging has been started")

# subsequent project files

import ccalogging    # import the module

log = ccalogging.log # point a script-level variable to the logger

log.warning("continuing to log to the same location as setup in the first file")
