Opinionated but handy app startup wrapper.
pyglib provides a clean, consistent setup for writing commandline scripts and applications in Python. It makes use of python-gflags and python-glog, and adds an app startup helper that deals with initialization boilerplate so you don’t have to think about it.
#!/usr/bin/env python from pyglib import app, gflags, log gflags.DEFINE_integer('bananas', 7, 'Number of bananas.') FLAGS = gflags.FLAGS def main(args): log.info('There are %s bananas.', FLAGS.bananas) log.debug('This will only show up if you run with --verbosity=10') if __name__ == __main__: app.run()
The above module is usable as a commandline app, complete with argument parsing and validation. It automatically has a few flags like --help and --verbosity that come from gflags and glog. Any positional arguments left over after parsing flags are passed along to the main() function.
This example module can also be imported as a library for use in another app. When used that way, any script that imports this one will inherit the --bananas flag defined here.
