Hello, Perhaps my previous message was too verbose, or there is someone still trying it out. After working on it some more, my question boils down to this: How the heck do I use read-line in a program? Take the following REPL session as an example: Gambit v4.2.6
(read) "This is an s-expression" ;<=typed "This is an s-expression" ;<=echoed (read-line) "" (read-line)This is an s-expression "This is an s-expression"
So, I know that I can call read-line from call-with-input-file, or call-with-input-string, but if I have an input file or a string, then I already have what I want. What I want is for the user to input a line of text, and for the program to do something with that line of text (as a string). However I use (read-line), it always accepts the text that was already there (usually "" or "\t"). How do I get it (or some other procedure) to accept user input? What would I put into (call-with-input-string ... read-line)? I've tried a few things, and I always just end up redefining read-line:
(define (read-this) (let ((input (read-char)) (output "")) (if (char=? input #\newline) output (string-append (string input) (read-this))))) (read-this) "" (read-this)this is text, baby "this is text, baby"
I'm really not getting this; can someone please explain it to me? Thanks, Joel -- Joel J.
