Click

Click ('Command Line Interface Creation Kit') is a Python package for creating composable, beautiful command-line interfaces with minimal boilerplate. It uses a decorator-based API to turn functions into CLI commands with automatic help page generation, argument/option parsing, type coercion, and shell completion. Current version is 8.3.1 (latest stable); the project follows a feature-release / fix-release cadence under the Pallets organization, with feature releases (e.g. 8.2.0, 8.3.0) potentially introducing deprecations or breaking changes and patch releases (e.g. 8.3.1) being safe upgrades.
