key=value style command argument parser

[Gribouillis]

i did not see anything about key=value arguments in that module, either.

Here is an example with plumbum.cli, a modified version of an example from the documentation

import logging
from plumbum import cli

logger = logging.getLogger(__name__)

class MyApp(cli.Application):
    @cli.switch("--log-to-file", str)
    def log_to_file(self, filename):
        print('Logging to file', filename)
        logger.addHandler(logging.FileHandler(filename))

    @cli.switch("--verbose", requires = ["--log-to-file"], excludes = ["--terse"])
    def verbose(self):
        logger.setLevel(logging.DEBUG)

    @cli.switch("--terse", requires = ["--log-to-file"], excludes = ["--verbose"])
    def terse(self):
        logger.setLevel(logging.WARNING)

    def main(self):
        logger.info('Execution of' + __file__)

if __name__ == "__main__":
    MyApp.run()

Output:
λ python3 paillasse/truccli.py --log-to-file=spam.txt --verbose
Logging to file spam.txt

As you can see, I used --log-to-file=spam.txt and it worked.
