Subject: How to break out of an emacs lisp loop ?
Date: Tue, 23 Oct 2007 18:29:00 -0000	[thread overview]
Message-ID: <1193164140.500795.322030@t8g2000prg.googlegroups.com> (raw)


(while (not (forward-char))
    (if (looking-at "a") break )

When I run this sexp, I get error at break. So break is wrong syntax.
But this is the way many C loops are written.

while ((c=(getchar()) != EOF){ if (c=='a') break; }

as in compilable running file:

#include <stdio.h>
main(){
int c;
  while ((c=getchar()) != EOF){ if (c=='a') break; }
}

So how do I break out of a loop in lisp ?
