Abstrys CLI Demos

This repository contains a number of CLI demos that represent Python + argparse patterns for creating various types of CLIs.

I strive toward easy-to-reuse, extensible design, and these demo CLIs are based upon this philosophy.

All the code is in the abstrys directory, here's a guide:

subcommand_cli_demo.py

This is a demo of a 'master' cli with subcommands (similar to git), each with their own set of arguments.

Each subcommand is represented by a "CliCommand" class (in src/abstrys/cli_common.py) derivative that implements two methods:

• set_up_parser(self, parser)
• run(self, args)

This allows encapsulation of each sub-command within its own source file, and makes adding a sub-command to the main CLI a one-line affair:

QuoteCommand(subparsers.add_parser("quote"))
