define abbrev for emacs-lisp-mode but not other lisp-mode

define abbrev for emacs-lisp-mode but not other lisp-mode

[Xah Lee]

this is a odd thing.

when in emacs-lisp-mode, and when you define a abbrev (e.g. call
define-mode-abbrev then “ah” then “add-hook”), then call write-abbrev-
file

then you get this in your abbrev file (e.g. at 〔~/.emacs.d/
abbrev_defs〕)

(define-abbrev-table 'lisp-mode-abbrev-table '(
    ("ah" "add-hook" nil 0)
))

note that it's lisp-mode-abbrev-table not emacs-lisp-mode-abbrev-
table.

Why's that?

(if you change it to the latter, it won't work.)

i'm wondering because i want the abbrev to be for emacs-lisp-mode
only, not general lisp mode.
It appears that emacs-lisp-mode is defined on top of lisp-mode. Ok, so
my question is, what's the purpose of lisp-mode? Is that supposed to
be the base for other lisp lang modes to be defined on top of? A look
at scheme-mode seems to confirm this, but still, i want my abbrev for
emacs lisp mode only. Is that possible?

thanks.

I would try the following in .emacs

(define-abbrev-table 'emacs-lisp-mode-abbrev-table '(
  ("ah" "add-hook" nil 0)))

(add-hook 'emacs-lisp-mode-hook (lambda()
         (setq abbrev-mode t)
         (setq local-abbrev-table emacs-lisp-mode-abbrev-table)))

I think that the nil argument after add-hook is deprecated in emacs ≥ 23.

Sorry, that's the 0 notation that is obsolete. It is now an optional property,
and is written as :count 0. See the docstring of define-abbrev.
