Re: Error:EOF after quote on input

 

Because READ respects certain characters reserved for lisp evaluations. A quote "'" is read as the function QUOTE:

(read "a") returns the symbol A, but

(read "'a") returns (QUOTE A)

It's the same thing that makes READ capable of returning lisp expressions, as in

(read "(cons 2 4)")

where the left parenthesis signals a lisp expression. Whenever READ bumps into a reserved character it expects an expression to follow. You'll have to check the returned character before using READ.

 

don't know if this will help or not - found it on another forum and thought i would pass it on

As indicated by welldriller's post, the following will cause the error:

_$ (read "'")
; error: EOF after quote on input

Since there are no expressions following the quote symbol.
