The Hitchhiker's Guide to CLIs in Python
summary
Shows how terminal ancestry and live modes cause quirks (canonical vs raw input, echo off, carriage return behavior) and uses stty -a shows modes examples to prove it. Implements a small git-like CLI with subcommands using sys.argv, getopt/argparse, docopt and then Click with decorator-based commands, demonstrates progress bars, colored output, editor prompts, config in XDG dirs and uses packaged to PyPI with twine to publish — each tool and step actually runs and the Click-based CLI works as shown.
