parenthesis matching in lisp mode

parenthesis matching in lisp mode

[Zimmen Gnauh]

   By parenthesis matching, I mean that the paired parenthesis are
highlighted when the cursor is on one of the parenthesis. How can I
make this work in lisp mode?

When in a lisp mode buffer do 

M-x show-paren-mode

or add this in your .emacs file to have this done automatically:

(add-hook 'lisp-mode-hook (lambda () (show-paren-mode)))

Nonsense.  You could enter the above just as
(add-hook 'lisp-mode-hook 'show-paren-mode)
but it would be equally wrong: it _toggles_ show-paren-mode every
time the lisp mode hook gets executed.

So please rather write
(add-hook 'lisp-mode-hook (lambda() (show-paren-mode 1)))

David mentioned already that this should be `(show-paren-mode 1)'.
Besides that `show-paren-mode' is a _global_ minor mode. So a simple

(show-paren-mode 1)

in your .emacs would do. You have it in all major mode then, but that
won't hurt IMO. If you really want it *only* in lisp-mode, you have to
make it buffer local first:

(add-hook 'lisp-mode-hook
	  (lambda ()
	    (make-local-variable 'show-paren-mode)
	    (show-paren-mode 1)))

Since `show-paren-mode' is a global minor-mode, I don't see whats good
in it turned on (and staying on) only after the 1st visit of elisp file.
I suggest to turn it on permanently in your initialization file.
Add    (show-paren-mode 1)    to your .emacs file. 

BTW. You can do it through `customize' (The way is: Editing -->
     Matching --> Paren Matching --> Paren Showing, or use
     M-x customize-apropos show-paren).
