REPL for Emacs Lisp

Based on this question: REPL on console emacs, you can use M-x ielm (inferior emacs lisp mode).

There is a (work in progress) REPL for Emacs for use from the command line. It currently supports basic command line editing and history.

The code is hosted on Github.

There is this project on Gitlab. The REPL can run on a termninal or on Emacs' minibuffer. Even if you run it in "no-window-system" mode (with -nw).
