Setting slime-enable-evaluate-in-emacs

Question

I am using SBCL with slime, and have the following code:

(swank::eval-in-emacs
  '(with-current-buffer (slime-repl-buffer)
     (insert (propertize "foo" 'font-lock-face '(:foreground "red")))))

(print "here is some text")

In general, if I try to execute anything with swank:: prefixed to it, emacs will give a security error, and this particular one tells me I need to set slime-enable-evaluate-in-emacs to true. Where is this value? I haven't been able to find a slime or swank config. & settings file. Thanks much.

You can simply add this to your .emacs:

(setq slime-enable-evaluate-in-emacs t)

If non-nil, the inferior Lisp can evaluate arbitrary forms in Emacs. The default is nil, as this feature can be a security risk.
