Vityou, I will give you an example though I myself sometimes doubt that I did it in the right way.
Anyway, here is what I did when I had exactly the same problem: - redefine and reexport #% top-interaction - provide #:language-info to the DrRacket's REPL (I am not sure if racket's REPL needs it too, but doing it will not hurt). The provided call should respond to 'configure-runtime key - the 'configure-runtime should trigger a setting of (current-read-interaction) parameter. - at the end of the implementation of (current-read-interaction), it should set another (current-read-interaction) that just returns EOF -- and then sets the original (current-read-interaction) back, so it is kind of a loop. The example (made long ago) is available at: https://github.com/kugelblitz/calc Relevant parts: /language.rkt (see top-interaction) /lang/reader.rkt (reference to lang-info) /lang/lang-info.rkt (calling of "configure runtime" handler) /lang/configure-runtime.rkt (the handler itself) Hope this helps.

I did reprovide all of the #%... forms from racket, and the repl works with base.rkt, it's when I have a reader that the repl doesn't work.
