fire-commands

Easy to use helper library for creating google fire based CLIs
https://github.com/google/python-fire

See example application firehelper_example for usage.

CLI entry point

In the CLI entry point, import relevant CLI commands, and use start_fire_cli initialise the fire app.

import firehelper
from .commands import *  #noqa

def main():
    firehelper.start_fire_cli('firehelper_example')

if __name__ == '__main__':
    main()

Commands

Import each command in the main app to ensure code to register the command is run.

To register commands:

print_commands = {
    'print': lambda mytext: print(mytext) 
}

firehelper.CommandRegistry.register(print_commands)

To register commands with subcommands:

maths_commands = {
    'maths': {
        'double': double,
        'square': square
    }
}

firehelper.CommandRegistry.register(maths_commands)

You can import all commands within a module as follows:

# commands.__init__.py
"""Ensure all commands to be registered are referenced here."""

__all__ = ['maths', 'print']

# __main__.py
from commands import *  # noqa
