Question

CLIM = Common Lisp Interface Manager, it’s like the REPL, ported to the GUI.

Is something like this similar possible in C++? If so, pointers?

Thanks!

Here’s a REPL built atop GNU C++:

There’s no reason why it shouldn’t work okay these days – it probably builds up a short program from successive statements, which on a modern machine will compile and run to display output in short order.

From the look of the examples, it could use a simple improvement: a line of input with no semicolon should be treated as an expression to be evaluated, so if you want to know the value of a, just enter a and it would be equivalent to:

std::cout << a << std::endl;
