When I'm running a program in the IDE, version 5.3.5--2013-06-18(-/f), for #lang racket, eg. 

#lang racket

(+ 4 5)
(/ 10 2)

When pressing Run >, the interaction window gets "9\n5\n" printed to the interactions window. The same version as R6RS

#!r6rs
(import (rnrs base))

(+ 4 5)
(/ 10 2)

It seems I get no output when pressing Run > when language is R6RS. Is there anywhere I can change this behavior, in Preferences perhaps?

  • Personally, I think it's broken to rely on top-level expressions being printed. (Sure, it's understandable if you're in a REPL, but this isn't a REPL, and also, I don't think R6RS modules support being used like a REPL.) Are you sure you can't just `display` them directly? – C.

  • @ChrisJester-Young I agree that it should not print anything when running as an application, but in a IDE one could break some rules to ease development. I'm currently using a macro (like `begin`) that uses display, but it's not optimal. – Sylwester Oct 27 '13 at 23:12
