Cheer.Router (Cheer v0.1.5)

Copy Markdown View Source

Routes argv through the command tree and dispatches to the matched command.

Handles the full dispatch pipeline: subcommand matching, option parsing (via OptionParser), default/env-var application, validation (required fields, choices, custom validators, cross-param validators, groups), and lifecycle hook execution.

This module is called internally by Cheer.run/3 and is not typically invoked directly.
