I'm playing around with SICP's Metacircular Scheme Evaluator, and thought it would be convenient to try and do that in a #lang setup in Racket, so I can use the Racket Definition Window and REPL. No Reader modification is needed, since Scheme code is already S-expressions. The expander just calls m-eval on each S-expression. This is my setup:
ME-test.rkt: #lang s-exp "ME-expander.rkt" (Scheme code ...) --- ME-expander.rkt: #lang racket/base (require (for-syntax racket/base)) (define-syntax (ME-module-begin stx) (syntax-case stx () [(_ s-expressions ...) #'(#%module-begin (for-each (lambda (expr) (displayln (m-eval expr))) (list 's-expressions ...)))])) (provide (rename-out (ME-module-begin #%module-begin)) #%top-interaction) (define (m-eval ... ; from here on the SICP Evaluator --- This works fine in the ME-test.rkt Definition window, but not in the REPL which doesn't have bindings for anything. I would like anything typed into the ME-test.rkt REPL to be used as argument to the ME-module-begin macro in ME-expander.rkt. When searching for this I found descriptions of REPL setups in a more complete #lang setup which I don't understand yet. Is it possible to make the REPL work in the setup above? Any other comments are also welcome. Many thanks in advance, Jan -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
