Simple REPL for C++
This library provides a simple way to expose any C/C++ function in a Read-eval-print loop (REPL) interactive environment.
Examples
Demo
We show how to use simple functions in the demo program. In this program we export three functions.
$ ./demo > help name (return type: parameter types) ; documentation greet (string: string) ; Say hi to someone. inc (int: int) ; Increase an integer value. mul (float: float int) ; Multiply a float with an integer. help (string:) ; This help message. exit (void:) ; Exit.
These are all functions without any side effect.
> greet world Hi world. > inc 2 3 > mul 1.2 3 3.6 > exit
Calculator
In the calculator program we show how to use class methods. In this program we export some simple arithmetic functions.
> help name (return type: parameter types) ; documentation add (void: int) ; Add something. sub (void: int) ; Subtract something. show (int:) ; Show result. help (string:) ; This help message. exit (void:) ; Exit.
These functions operate on an object.
$ ./calculator > show 0 > add 10 > sub 2 > show 8 > exit
