a couple of novice questions

a couple of novice questions

[Mitch Edelman]

apologies for newbie question - using Xemacs (for windows)how does one 
display the line number of the file currently being edited?

Secondly, how does one find a matching opening brace, paren, etc?

Finally, in editing a document where it's reasonable for "<" to
be unpaired (as in javascript code inside an html document), how
does one find the opening prace, paren, etc.

Thanks in advance,

Mitch Edelman

It's  automatic. When  you  close a  paren,  the cursor  moves to  the
matching  opening paren.   Or, if  you double-click  on one  paren, it
selects all  its contents and  the matching paren  too. Or if  you use
backward-sexp or forward-sexp (C-c , or C-c .), it moves over matching
paren.

I don't  think modes can be  defined locally.  In these  cases, I just
change the major mode.  It may help to use narrow-region and widen.

I use C-M-p (backward-list) and C-M-n (forward-list).

,----[ C-h f backward-list RET ]
| backward-list is an interactive compiled Lisp function in `emacs-lisp/lisp'.
| It is bound to C-M-p.
| (backward-list &optional ARG)
| 
| Move backward across one balanced group of parentheses.
| With ARG, do it that many times.
| Negative arg -N means move forward across N groups of parentheses.
|

Also you can look at:

,----[ C-h v blink-matching-paren RET ]
| blink-matching-paren's value is t
| 
| *Non-nil means show matching open-paren when close-paren is inserted.
| 
| You can customize this variable.
| 
| Defined in `simple'.

Try this in your .emacs

;; Blink the parent character
(defun start-flashparen()
  (progn
    (require `flash-paren)
    (flash-paren-mode 1)))

I use M-x show-paren-mode.  This highlights the paren at point and
its opening/closing counterpart, if any.

Or you can use the more sophisticated mic-paren.el which you can download from
http://www.emacswiki.org/elisp/index.html ....
