Re: [racket-users] Proper handling for a custom current-read-interaction?

I don't know how change the terminal IO to send eofs, but I believe that ocaml has a special ;; character in the language specially for handling situations like that. In other words, the user has to explicitly delimit REPL interactions (but they don't have to do that in other contexts). Robby

Re: [racket-users] Proper handling for a custom current-read-interaction?

Ah, ok, that (mostly) makes sense to me. I think this might be a little bit complicated, though: in this language, definitions can span multiple lines without necessarily any direct indication that they continue. Think Haskell-style pattern matching: fib 0 = 0 fib 1 = 1 fib n = fib (n - 1)

[racket-users] Problem when redefining #%app

I'm writing a #lang using a custom #%app that transforms all multi-argument applications into nested unary applications. I've run into trouble where a macro (written in standard Racket but to be used in the #lang) is malfunctioning because when the expander processes the macro's output, it uses
