8.2 REPL: the “top level”

SLIME uses a custom Read-Eval-Print Loop (REPL, also known as a “top level”, or listener). The REPL user-interface is written in Emacs Lisp, which gives more Emacs-integration than the traditional comint-based Lisp interaction:

To load the REPL use (add-to-list 'slime-contribs 'slime-repl) in your .emacs.

C-c C-z
M-x slime-switch-to-output-buffer
Select the output buffer, preferably in a different window.
C-c C-y
M-x slime-call-defun
Insert a call to the function defined around point into the REPL.
C-c C-j
M-x slime-eval-last-expression-in-repl
Inserts the last expression to the REPL and evaluates it there. Switches to the current packae of the source buffer for the duration. If used with a prefix argument, doesn't switch back afterwards.
