title: Interactive command line mode emacs
body: <p>Can anyone suggest any pointers / tutorials or information on how to get an interactive command-line mode in emacs. I have looked at comint and shell modes but these talk to a sub-process. I just want an interactive command line that talks to an elisp function, not a sub-process like <code>/bin/bash</code>. The idea is to use it to interact with simple interpreters written in elisp (just for fun).</p>
