define-key upon common-lisp-mode and inferior-lisp-mode

[wilnerthomas--- via Users list for the GNU Emacs text editor]

Have encountered "common-lisp-mode" but there does not exist "common-lisp-mode-map".

Thusly  (define-key common-lisp-mode-map KEY DEF) fails
Also seen "inferior-lisp-mode-map". which has no associated "inferior-lisp-mode".  What is "inferior-lisp" and can one use it like lisp-mode?  Does it make sense to call "define-key" upon "inferior-lisp-mode-map"?

Its doc string says:

  In addition to any hooks its parent mode ‘lisp-data-mode’ might have
  run, this mode runs the hook ‘lisp-mode-hook’, as the final or
  penultimate step during initialization.

So this mode inherits the keymap from its parent, lisp-data-mode.

As for binding keys, it is better to use local-define-key, I think.
It will figure out the keymap for you.

Like below?

(local-define-key common-lisp-mode-map (kbd "H-e") #'eval-last-sexp)

A bit non-standard compared to other modes.

Yes.

AFAIU, you are a user, not a programmer who defines a new mode.  the
above is the standard way for users to define key bindings for the
current mode.

Most of my time is spent doing programming work for others.

Have got "Lisp error: (void-function local-define-key)" for "Emacs 27.2".

On the other modes I have been using 

(define-key emacs-lisp-mode-map (kbd "H-e") #'eval-last-sexp)

The last seems more standard for many modes.

On my machine, `C-h o common-lisp-mode RET` tells me:

    common-lisp-mode is an alias for ‘lisp-mode’ in ‘lisp-mode.el’.

Really?  They're both defined in the same `inf-lisp.el` file.
AFAIK it's a mode that used to be used for a buffer containing
common-lisp REPL running in a subprocess.  I suspect nowadays people use
Slime or SLY which I expect don't use `inf-lisp.el` any more.
Then again, I thought `lisp-mode` wasn't used by those modes either but
I was proved wrong, so maybe they do still use `inferior-lisp-mode`
as well?

Use local-set-key instead.

I can only show you the better solutions, I cannot force you use them.

What can be the origin of the Lisp Error?

What does the error message say, again?

That function doesn't exist.  I missed the fact that you used a wrong
name in the original question, sorry.

"Lisp error: (void-function local-define-key)" for "Emacs 27.2".
That function does not exist.  Neither does "common-lisp-mode-map", although
the mode "common-lisp-mode" is available for use.

And I am not able to use its parent, lisp-data-mode, lisp-data-mode-map, or similar.

Well, that's clear enough, isn't it? Do you think a function
by that name should exist? If yes, why do you think that? If
no, what is your problem?

Eli mentioned it, but is was a mistake.  The problem is that I discovered 
"common-lisp-mode" but there is no "common-lisp-mode-map".

The documentation says local-set-key is legacy, and should be replaced
by keymap-local-set.

But aside from that, I only use define-key, and it works pretty good.
What are the advantages of using keymap-local-set? When using define-key
with the mode specific map, I'm not polluting other keymaps. So why the
need for a local function?

I don't know if this can help, but usually when I encounter these errors
I do a `M-x grep-find`. For instance, looking in
/usr/share/emacs/29.0.50/lisp/, with

find . -type f -exec grep --color=auto --include=*.el -nH --null -e \
common-lisp-mode-map \{\} +

I found

;; Used in old LispM code.
(defalias 'common-lisp-mode 'lisp-mode)

So, maybe it is correct that common-lisp-mode-map doesn't exist, as you
should use lisp-mode-map?

In the version which says that, use keymap-local-set, if you prefer
that.  But local-set-key is not going anywhere any time soon, so I
wouldn't worry about that, if you need to write code for multiple
versions of Emacs, or help people who might use released versions
(which is what happens here).

The advantage is that you don't need to care about the mode and its
map.  Which was a problem in this case, so I thought I was helping.

You're right, and as a matter of fact, from the doctring I cannot see when
that advice was introduced.

Thanks, that's something I can use too. Usually I use define-key because
I'm setting my init file, and I know (almost everytime) which mode I'm
customizing. Anyway, your suggestion is super useful. Thanks!
