cli-erAdvanced type-safe CLI builder

Build modular, well-structured CLI applications using a definition object. Includes help generation, routing, hooks, plugins, and more.

Help generation

Automatically generates scoped help for all commands and namespaces, with support for parent-scope options and custom templates.

Resolves command handlers via a predictable folder-structure strategy, keeping large CLIs clean and maintainable.

Execute code on beforeParse, afterParse, beforeExecute and afterExecute events. Bundle hooks into reusable plugins.

Read options from config files (JSON, INI, …) and from environment variables matching a prefix — no manual wiring required.

Override any library message via CliOptions.messages to build fully internationalized CLIs.

Typed command and namespace options via Cli.defineCommand / Cli.defineNamespace helper utilities.
