The Design of a Versatile CLI that Supports Command Set Dynamically Loading

Abstract

This paper mainly describes the design of a versatile CLI that supports command set dynamically loading. It not only explains the overall architecture and operation flow in detail, but also the implementation methods of every module and the important data structures. This CLI has the open architecture, not only the user can enjoy the advantages of unified management, but also can install new command sets dynamically for different applications. The design principles of this system are scalability, expandability and portability, which providing a reference direction for versatility of CLI on embedded system.
