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
