Name
libsrg -- count calls to python logging at each logging severity level
Description
libsrg provides the following classes:
- libsrg.LoggingCounter
- extends logging.Handler with count of logs at each severity level
- counts on output, so logs suppressed by current logging level do not get counted
- atexit hook used to print statistics on program exit
- libsrg.LoggingAppBase
- application base class with LoggingCounter installed
- argparse.ArgumentParser
- --verbose sets logging level to DEBUG
- --logfile directs logging to a file
- Derived classes can add application specific options to ArgumentParser
- libsrg.Runner
- run command line in a subprocess
- capture stdout, stderr
- try catch block for exceptions
- exceptions can optionally be raised back to calling program
I write a lot of smallish command line utilities for internal use, and factored out some common repetitive boilerplate code into this package. Published for my own installation convenience, but might be useful to others as well.
Example output
Library uses atexit hook to summarize logging activity counts and total execution time. Counts are also available to the program at runtime.

Testing
Pytest performs its own logging setup before calling any user supplied tests, so it doesn't work well testing these classes logging setup. Ad-hoc test code is supplied at the end of the classes and executes if the class is loaded as main.
Roadmap
My intention is to keep this library small. It is not expected to evolve into an all-purpose framework. Output is geared towards developers, not end users.
