I don't think you can reproduce the REPL in DrRacket exactly very easily
because I think it relies on some internal classes (and mixins) that are
defined in DrRacket itself.

But if you want to set up a text editing with similar features, you can
use the classes/mixins provided by the GUI framework library.

DrRacket itself uses a bunch of these mixins to build its text editor:

The classes/mixins are documented here:
