basecmd 0.1.4

Logging boilerplate for the command line

basecmd

Boilerplate for the command line.

Classes inheriting from BaseCmd have a self.log attribute that is a standard Python logger. A basic logging configuration to sys.stdout is provided.

For command line options controlling the logging verbosity and output to a log file, call the command with -h or --help.

Defaults for logging options can be also provided as environment variables or in a .emv file:

• LOG_LEVEL: the logging verbosity, one of error, warn, info, or debug; default: info. ' LOG_FILE: path to a log file, defaults to the standard output for easy redirection.
• LOG_FORMAT: a standard Python logging format, defaults to %(asctime).19s %(message)s when logging to a file or a terminal and %(message)s otherwise.

When logging to a terminal, the output is colored by log level.

Example usage

from basecmd import BaseCmd

class MyCmd(BaseCmd):

    def add_arguments(self):
        self.parser.add_argument('--foo',
            help='Custom command line option')

    def __call__(self):
        self.log.debug(self.options.foo)

if __name__ == '__main__':
    cmd = MyCmd
    cmd()
