What you find here behaves similarly to what you also find in Python. This includes hierarchic loggers, multiple handlers at each logger, the possibility to specify a formatter for each handler (one default formatter is given), same levels (names and numeric values) as Python's logging package, a simple logging.BasicConfig function to quickly put yourself in a usable situation...
This package owes a lot to Brian Lee Yung Rowe's
futile package and the
documentation of the Python logging package.
Index: basicConfig bootstrapping the logging package
addHandler add a handler to a logger getLogger set defaults and get current values for a logger removeHandler remove a handler from a logger setLevel set logging.level for a logger
to use this package, include logging instructions in your code, possibly like this: logging::basicConfig() logging::addHandler(logging::writeToFile, name="company", file="sample.log") logging::info("hello world", logger="") logging::warn("hello company", logger="company.module")
the basicConfig function adds a console handler to the root
logger, while the explicitly called addHandler adds a file
handler to the 'company' logger. the effect of the above example is two
lines on the console and just one line in the sample.log file.
