simple elisp question

[Jeffery B. Rancier]

Hi All.

When I call find-tag, I prefer the method/function to appear at the
very top of the buffer.  So, I added the following:

,----
| (add-hook 'find-tag-hook 
| 	  (function 
| 	   (lambda()
| 	     (interactive)
| 	       (recenter 0)
| 	       (beginning-of-line))))
`----

That worked fine, but now when I call pop-tag-mark the place from
where I called find-tag, is not preserved.  I don't a call to
save-excursion will help here.  Any ideas?
-- 
Thanks,
Jeff

Simple elisp question

[Chris McMahan]

Here's a basic elisp question:

I want to use the value of a variable within a list, rather than the
name of the variable. How do I do this? Here's the code in question.

(setq gnus-select-method
      '(nntp "news_server"))

I want to replace the hard-coded "news_server" with the value of a
variable I've defined called my_news_server defined with
  (setq my_news_server "news_server")

I apologize for the basic nature of the quesiton, but I've not been
able to find an answer in the elisp manual.

- Chris

(list 'nntp my_news_server)

or the fancy way (read in th elisp manual about backquote
and unquote):

`(nntp ,my_news_server)

Two ways, which differ only in how they look (i.e., either way will
work; choose the one that seems least weird :-))

        (setq gnus-select-method `(nntp ,my_news_server))

or

        (setq gnus-select-method (list 'nntp my_news_server))

Thanks to all who replied.

I'm going with the following format:

        (setq gnus-select-method (list 'nntp my_news_server))

So here's the final entry in my .gnus file:

(setq gnus-select-method
      (list 'nntp my_news_server
            'nntp-port-number 9119))

Oops! Helps to test things out before posting.

Here's the final entry in my gnus file. I've used the other syntax
here as an example as well for my own reference.

;;; my_news_server and my_news_ports are set in the ~/.emacs file
(setq gnus-select-method
      (list 'nntp my_news_server
            (list 'nntp-port-number my_news_port)))

; alternate syntax for setting the list
;(setq gnus-select-method
;      `(nntp ,my_news_server
;               `(nntp-port-number ,my_news_port)))


thanks to all who helped!!
