C library to easily create interactive shell

I want to create a program like gdb or gnuplot that has it's own command prompt. I'm looking for a library that will handle the parsing/input validation as well as provide a command history. So far googling for this topic is difficult because any search with the terms 'c' and 'shell' will only produce results for 'csh'.

History is usually managed by readline or libedit. Parsing is usually done with flex/bison.

I can recommend CLI parser. It is quite suited for your described use case.

CLI Parser provides a framework for quickly development of Cisco-like CLI commands. It provides a simple syntax to define CLI commands, a compiler to automatically convert these commands into a C parse tree and a run-time library to create CLI.
