Flam Description

A minimalist Python application framework Flam provides utility functions and classes used in 99% of applications (written by the author).Currently it provides: * Application bootstrapping. * Flag management. * Command-line commands.Application bootstrappingTypically all an application writer wants to do is run a main() function, register some flags, maybe take some action based on a command-line argument, set up logging defaults.Releasepeace's "run" command takes care of all this: from flam import define_flag, flags, command, run define_flag('-l', '--long_listing', help='long listing', default=False, action='store_true') @command def ls(path): if flags.long_listing: ... else: ... def main(args): # Some initialisation code here... ... if __name__ == '__main__': run(main) run() will parse command line flags, call main with any remaining arguments, then finally dispatch to any commands registered with @command, in this case "ls".Command ManagementFlam provides support for both command-line flags and commands, where commands are actions passed on the command-line.For example, the following will register an "init" command: @command def init(path): """Initialise the system.""" db = sqlite3.open(path) ...Which can then be used like so: python myapp.py init somefile.dbHelp is automatically generated by inspecting the registered command functions: $ python myapp.py help Usage: myapp.py < command > ... Commands: help Display help on available commands. init < path > Initialise the system. Options: -h, --help show this help message and exit --flags=FILE load flags from FILE --logging=LEVEL set log level to debug, info, warning, error or fatal Flag ManagementRegister new flags with flam.define_flag(). This is an alias for optparse.OptionParser.add_option() and thus accepts exactly the same arguments.The underlying optparse.OptionParser object is exposed as flam.flag_parser.Call flam.parse_args() to parse command-line arguments. Defaults to parsing sys.argv.flam.flags is an optparse.Values() object that will contain the parsed flag values.The --flags=FILE flag can be used to load flag values from a file consisting of "key = value" lines. Both empty lines and those beginning with # are ignored. Requirements: · Python
