Question

I want to read input from STDIN, and just read what it is: if input is a list, then what is read is a list. However, the read-line function seems always return a string!
For example: in clisp interactive envrironment:

(read-line)

I input:

("(define M ::int )" "(define X ::int )")

The it will give me back a string:

"(\"(define M ::int )\" \"(define X ::int )\")" ;

What I want is still the original list: ("(define M ::int )" "(define X ::int )")

So How to make the read-line read in what the input it was?

Answer 1

(let ((a read)))
   (eval a))

(+ 2 2 2)

=> 6

there’s a reason they call it a READ EVAL PRINT LOOP.
