Chuda

Chuda is a very simple Python3 framework to create CLI (Command-Line-Interface) tools.

It will handle for you some basic stuff: parse configuration file, logging, argument parsing, signal handling etc...

Features

• Represent commands and argparse arguments by Python classes
• Handle parsing of a configuration file for you (INI, JSON, or YAML with pyyaml)
• Provide you a configurable logger, and some basic options to quiet/verbose mode
• Signals handling by decorator

Example

import sys
import signal
from chuda import App, autorun, Command signal_handler, Option


class FooSubcommand(Command):
    command_name = "foo"
    description = "a foo subcommand"

    def main(self):
        self.logger.info("foo")
        self.app.subcommands["bar"].run()


class BarSubcommand(Command):
    command_name = "bar"
    description = "the ultimate bar subcommand"

    arguments = [
        Option(name=["--path"], default="~")
    ]

    def main(self):
        process = self.shell.run(
            "ls", cwd=self.arguments.path
        )
        self.logger.info(process.output)


@autorun()
class FooBarApp(App):
    app_name = "foobar"
    description = "Foobar application"

    config_path = ["./config.ini", "../config.ini"]

    subcommands = [FooSubcommand, BarSubcommand]

    @signal_handler(signal.SIGINT)
    def handle_ctrl_c(self, signum, frame):
        self.logger.info("Stopping...")
        sys.exit(2)
