Click: A Pleasure To Write, A Pleasure To Use
summary
Demonstrates building a working "ad notifier" CLI that scrapes Craigslist with BeautifulSoup, detects new listings via a simple cache (file or Redis), and sends notification emails, using click for decorator-based commands, options/flags, subcommands and environment-variable defaults. Shows how to share global settings through a context object, get automatic help and parameter validation, write unit tests with click’s test runner, and enable bash autocompletion for a pleasant, composable CLI that runs as a one-off or periodic job.
