Picocli comes with an annotation processor that automatically Graal-enables your jar during compilation. Which can be distributed as a single executable file. Picocli-based applications can be ahead-of-time compiled to a native image, with extremely fast startup time and lower memory requirements, This lets users run picocli-based applications without requiring picocli as an external dependency. In a single file, so you can include it in source form. It features usage help with ANSI colors and styles, TAB autocompletion and nested subcommands. Picocli is a modern library and framework, written in Java, that contains both an annotations API and a programmatic API. Picocli aims to be the easiest-to-use way to create rich command line applications that can run on and off the JVM.Ĭonsidering picocli? Check what happy users say about picocli.
