REPL for Emacs Lisp
What are some REPLs for Emacs Lisp?
Is there only one that is within Emacs?
Are there some that run inside terminal outside Emacs?
Solution 1:
Based on this question: REPL on console emacs, you can use M-x ielm (inferior emacs lisp mode).
Solution 2:
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.
Solution 3:
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).
