Hello,
This is a bit OT, but I'd be interested by learning how to get a better
environment for editing ELisp code.
Currently, the only friends I have are ElDoc and C-h f/v for navigation to
symbol definitions. This is rather primitive, isn't it?
When I see what CEDET and ECB seem to offer -- though I'm not using them, not
coding in C/C++, etc. -- , I'm quite jealous.
Questions that I have:
- Do you use TAGS?
- If yes, why don't we make TAGS from within the Makefile?
- If yes, which ones: Emacs-style TAGS, Exuberant Ctags, GNU GLOBAL tags?
- What do you use to jump from the point where a symbol is used to the point
where a symbol is defined (other than using C-h f/v)?
- How do you return to your previous location?
- Are you able to use CEDET/ECB for Emacs Lisp?
- Are you willing to share extract of your interesting configuration scraps?
Best regards,
Seb

Well, I don't use eldoc (I should.)
My setup is also quite primitive.

I use registers a lot. I register the point, the window configuration,
I register chunks of text, etc.
I also use ElScreen, which implements tabs for Emacs:
http://www.emacswiki.org/emacs/EmacsLispScreen
I could not actually live without ElScreen and I can't wait to use
something native.

Usual commands (C-x C-x) and registers.

No.

Configuration is like hair: with age, you somehow become minimalist :)
Besides using register-list.el¹, I don't have any particular setup.
Sorry I can't help more! Looking forward reading other answers...
Best,

For all practical purposes, I find this be sufficient.
(global-set-key (kbd "C-c f")
(lambda ()
(interactive)
(require 'finder)
(let ((thing (intern (thing-at-point 'symbol))))
(if (functionp thing)
(find-function thing)
(find-variable thing)))))
Put your cursor on a variable or a function, C-c f and you are staring
right at the definition of the variable or function. For this to work,
the library defining the function or variable should already be loaded.

Just discovered this from find-func.el
(require 'find-func)
(find-function-setup-keys)
will install the below keymap for you.
It would have been more practical if these functions, made a decision of
whether some symbol is a function or a variable automatically. There is
also this C-x K.
,----
| (defun find-function-setup-keys ()
| "Define some key bindings for the find-function family of functions."
| (define-key ctl-x-map "F" 'find-function)
| (define-key ctl-x-4-map "F" 'find-function-other-window)
| (define-key ctl-x-5-map "F" 'find-function-other-frame)
| (define-key ctl-x-map "K" 'find-function-on-key)
| (define-key ctl-x-map "V" 'find-variable)
| (define-key ctl-x-4-map "V" 'find-variable-other-window)
| (define-key ctl-x-5-map "V" 'find-variable-other-frame))

Thanks for pointing this out, I have a feeling the find-func
functionality will quickly become core to my elisp file navigation.
To answer the original question, I also tend towards a minimal setup. I
do all of my editing directly in elisp source files, and I don't use
tags or etags or anything like that.
I use the describe-function and describe-variable help functions with
tab completion *very* frequently to find functions and variables
relevant to my current task, and to then jump to their source.
When drilling into either a bug or unfamiliar functionality I find
edebug invaluable. Evaluating functions with a prefix argument "C-u
eval-defun" instruments them for interactive step-by-step evaluation
with edebug.
Also, I highly recommend both paredit and the sexp-edit operations
(kill-sexp, paredit-backward-up, paredit-forward, etc...) to anyone
working on any lisp source code.
