This library is an extension for Sly that enables the overlay of Common Lisp evaluation results directly into the buffer in the spirit of CIDER (Clojure) and Eros (Emacs Lisp).

The primary function to call is sly-overlay-eval-defun, which can be bound to whatever is usually bound to sly-eval-defun.

There is otherwise no other special setup necessary for using the library.

sly-overlay is available on MELPA.

sly-overlay is already incorporated into Doom and is the default binding for SPC m e d.
