FAQPage Schema

How do I build a Java CLI tool using annotations?▼

To build a Java CLI tool using annotations, use the Crest framework to define commands with @Command and parse options with @Options, reducing boilerplate. Loaders and interceptors manage execution and validation for a consistent developer experience.

What is an annotation-driven command-line interface and when do I need it?▼

An annotation-driven command-line interface uses metadata to declare commands and options, reducing manual parsing code. You need it when building Java CLI tools that require consistent help output, multi-level command groups, and extensible validation without boilerplate.

Can I group multiple commands and add custom validation in Java CLI applications?▼

Yes, you can group multiple commands using Crest's multi-level group support and add custom validation via @CrestInterceptor. This allows you to intercept command execution, integrate custom editors, and enforce validation rules within your Java CLI application.

Does the Crest Java CLI framework require external dependencies to run?▼

No, the Crest Java CLI framework operates with no external dependencies. You can build and run command-line tools using its built-in Loader APIs, @Command annotations, and help output generation directly within your Java environment.

How do I generate help output for a Java command-line application?▼

You generate help output for a Java command-line application by creating a command class annotated with @Command and running it using Crest's builder. The framework provides built-in help generation that automatically formats commands and options for the user.
