In most character-buffered REPLs the enter key serves two purposes: quoting a new line character and submitting input to the REPL. Some systems like Mathematica require a special key combination like shift-enter or control-enter to submit input. That is a clean separation of concerns but it is awful to use, though it makes a bit more sense in a multi-line notebook environment like Mathematica as opposed to a more line-oriented REPL.
SBCL's REPL works as suggest but there are other REPLs that work more like Clojure's. I prefer Clojure's current behavior by a small margin. It feels more natural for a line-oriented REPL. -Per On Fri, Apr 2, 2010 at 2:23 PM, Michael Jaaka <[email protected]> wrote: > Hi! > > I think that I've found inconsistency in REPL behavior. > Just press ENTER in REPL and you got new command prompt. > This shouldn't work like this.
