CLI Parser

CLI Parser is a free and open source project that provides a framework for quickly developing Cisco-like CLI commands. It facilitates creating CLI through a simple syntax and a run-time library, along with a compiler that automatically converts these commands into a C parse tree.

To use CLI Parser, you will need to provide specific files and functions. Firstly, you will need to provide .cli files, which define CLI commands, and then use mk_parser.py to compile them into a parse tree used by libparser.

Additionally, you will need to supply action functions that act as callback functions when a CLI command is accepted by CLI parser. And finally, you will need to provide I/O functions as prototypes, which are listed in parser_io.h. These functions connect CLI parser to the system I/O, with Linux/UNIX providing these functions while for other systems, you will need to provide your own.

Overall, CLI Parser is an efficient tool that simplifies the development of CLI command frameworks while maintaining open-source availability for everyone.
