Emacs Lisp does not seem to have a PPRINT function. How do you pretty print an S-EXP in elisp the way you can in Common Lisp?
Thanks!

Assuming that the result of cl-prettyprint
is good enough for you, here's how to get its output in a stream.
(defun pprint (form &optional output-stream)
(princ (with-temp-buffer
(cl-prettyprint form)
(buffer-string))
output-stream))
Use the pp
library which is part of GNU Emacs. For example you can use pp-macroexpand-last-sexp
for prettifying an sexp.
