95.87.231.111: The simplified code (albeit working) does not represent a proper Emacs hook, so I've restored the original version

{{package
| name=IELM
| description=Emacs Lisp REPL
| author=David Smith

}}

'''IELM (Interactive Emacs Lisp Mode)''' is a nice mode that gives you an interactive [[Emacs Lisp]] shell (or a {{Acronym|REPL|Read-Eval-Print Loop}} if you prefer) that you can use for exploratory programming. You can start it by pressing {{Command|ielm}}. You'll be taken to a buffer named {{Buffer|*ielm*}}, where Emacs Lisp expressions you've entered will be evaluated on pressing the Return key. IELM offers some nice features like tab autocompletion of symbol names and the ability to span an expression over several lines.








= Basic setup =

IELM is bundled with Emacs by default. No additional setup is required.

= Common Customization =


== Show {{ModeLink|eldoc}} in IELM ==
<source lang="lisp">
(defun my-ielm-mode-defaults ()
(turn-on-eldoc-mode))

(setq my-ielm-mode-hook 'my-ielm-mode-defaults)

(add-hook 'ielm-mode-hook (lambda () (run-hooks 'my-ielm-mode-hook)))
</source>

= Recommended Reading =

* [[Emacs Lisp]]
* [[REPL]]
