This example demonstrates a command-line hiking trail finder built in Ruby, using the `HikingProject::CLI` class to manage user interaction. It shows a text-based menu system where users enter coordinates and select from a list of trails, with each trail’s details displayed as plain text output. The code relies on Ruby’s built-in `gets` for input and `puts` for output, with no external libraries or APIs. It illustrates a simple loop-based control flow, handling user choices like “list,” “restart,” or “exit” to relist trails or show full descriptions. The data source is hardcoded sample trail summaries, and no rendering or visualization beyond terminal text is performed.
