Please recommend packages for editing elisp

Hello, I just started reading "An Introduction to Programming in Emacs Lisp." https://www.gnu.org/software/emacs/manual/html_node/eintr/index.html For now I have the rainbow parentheses package installed but I was wondering if there are other useful packages for learning elisp.

[Vlog: Emacs is my "favourite Emacs package"](https://www.youtube.com/watch?v=RiXK7NALgRs) Seriously though. It's already got everything you need. Rainbow-parentheses is cool, but `show-paren-mode` is already built-in. One external package I might recommend (though I haven't actually used it in a while myself) is `aggressive-indent`. It indents everything as it should be indented, as soon as you edit a line. This makes it plainly obvious when you've got one or more parentheses in the wrong places. Also, the built-in `electric-pair-mode` is great. You might need to tweak the settings a little to get it to work the way you want, but it's very helpful.

(use-package lisp :hook (after-save . check-parens)) (use-package elisp-mode :bind (:map emacs-lisp-mode-map ("C-c C-d C-d" . describe-function) ("C-c C-d d" . describe-function) ("C-c C-k" . eval-buffer))) (use-package highlight-defined :ensure t :custom (highlight-defined-face-use-itself t) :hook (help-mode . highlight-defined-mode) (emacs-lisp-mode . highlight-defined-mode)) (use-package highlight-quoted :ensure t :hook (emacs-lisp-mode . highlight-quoted-mode)) (use-package highlight-sexp :quelpa (highlight-sexp :repo "daimrod/highlight-sexp" :fetcher github :version original) :hook (clojure-mode . highlight-sexp-mode) (emacs-lisp-mode . highlight-sexp-mode) (lisp-mode . highlight-sexp-mode)) (use-package eros :ensure t :hook (emacs-lisp-mode . eros-mode)) (use-package suggest :ensure t :defer t) (use-package ipretty :defer t :ensure t :config (ipretty-mode 1)) (use-package nameless :ensure t :hook (emacs-lisp-mode . nameless-mode) :custom (nameless-global-aliases '()) (nameless-private-prefix t)) (use-package erefactor :ensure t :defer t) (use-package flycheck-package :ensure t :hook (emacs-lisp-mode . flycheck-package-setup)) (use-package elsa :defer t :ensure t) (use-package flycheck-elsa :ensure t :hook (emacs-lisp-mode . flycheck-elsa-setup))

Learn how to use built-in stuff: edebug, built-in elisp manucal (C-h i) and C-h f/v are your best friends. Built-in electric-pair-mode, eldoc-mode and fill-mode are very useful. Outside packages I use: paredit, speed-of-thought-lisp, lisp-extra-font-lock, macrostep, company, helm + many helm addons ), expand-region and yasnippet are probably ones I use most. A few snippets I find useful on an everyday basis: ;; From: https://emacs.wordpress.com/2007/01/17/eval-and-replace-anywhere/ (defun fc-eval-and-replace () "Replace the preceding sexp with its value." (interactive) (backward-kill-sexp) (condition-case nil (prin1 (eval (read (current-kill 0))) (current-buffer)) (error (message "Invalid expression") (insert (current-kill 0))))) ;; https://stackoverflow.com/questions/2171890/emacs-how-to-evaluate-the-smallest-s-expression-the-cursor-is-in-or-the-follow (defun eval-next-sexp () (interactive) (save-excursion (forward-sexp) (eval-last-sexp nil))) ;; this works sometimes (defun eval-surrounding-sexp (levels) (interactive "p") (save-excursion (up-list (abs levels)) (eval-last-sexp nil))) Make your self also some shortcuts you find easy to remember and use. These are what I find useful: (defkeys emacs-lisp-mode-map "\C-c a" emacs-lisp-byte-compile-and-load "\C-c b" emacs-lisp-byte-compile "\C-c c" emacs-lisp-native-compile-and-load "\C-c d" eval-defun "\C-c e" eval-buffer "\C-c r" eval-region "\C-c l" eval-last-sexp "\C-c n" eval-next-sexp "\C-c i" reindent-buffer "\C-c p" fc-eval-and-replace "\C-c s" eval-surrounding-sexp) But don't put too much time on chasing packages. There is a lot of built-in stuff you can use. If you are learning Emacs Lisp, I can also recommend this year's [Advent of Code](https://adventofcode.com/).

Not a list of packages, but for learning Elisp this might help: https://www.emacswiki.org/emacs/LearnEmacsLisp

I can recommend `prism`, `topsy`, `highlight-function-calls`, `lispy`, and `aggressive-indent`. My Elisping would be much less enjoyable without them. For more, look at my config here: https://github.com/alphapapa/ap.el
