gnus-topic and popmail access

gnus-topic and popmail access

[d. hall]

I've read the gnus-info for sgnus, and noticed the entry for popmail (it
seems rather... lacking in info).  like even though it said put po: or pop
in the nnmail-spool-file, i don't see where it can find the popserver
address or... or what to use for a password.

also is gnus-topic broken? or do i have to setup variables before i attempt
to use it?

Gnus just calls (in most or all? cases) movemail to get the mail out of the
spool.  Movemail comes with emacs, but doesn't seem to be documented
anywhere.  From a comment in movemail.c (under as lib-scr/movemail.c in the
emacs source distribution):

/*
 * Modified January, 1986 by Michael R. Gretzinger (Project Athena)
 *
 * Added POP (Post Office Protocol) service.  When compiled -DPOP
 * movemail will accept input filename arguments of the form
 * "po:username".  This will cause movemail to open a connection to
 * a pop server running on $MAILHOST (environment variable).  Movemail
 * must be setuid to root in order to work with POP.

That's about it.  This really should be documented somewhere, if not in the
Gnus docs then at least in the emacs manual.

Ugh!  Well, one reason why I've always liked emacs was there was always
another way around it.  Just in case I haven't compiled movemail with
-DPOP, and I don't have it setuid root... but I do have access to
popclient, and know how to write a hook function.

At first I wrote a perl script called mailgrab to append the popspool to my
current spool, unfortunately it required that I keep the password located
in a perlscript (for ease and convience).  I looked at ange-ftp's elisp,
and I worked out a hook-function which is part of gnus-get-new-news-hook.
Now it works all fine and dandy... no in regards to my other question about
gnus-topic... public feature, or private bug? (on the next Geraldo...)

Works just fine in Sgnus v0.26.  If you had been using it before, you might
want to remove topic variables in your .gnus (gnus-init-file).

Topics are now a minor mode of *Group* mode, and can be toggled by hitting
't' in the *Group* buffer.  If you want it on permanently do

(add-hook 'gnus-group-mode-hook 'gnus-topic-mode)

Once you've got topics running, you can create and move them with the T
keymap.  Do 'T C-h' to find out what all those keys do.  I believe all the
newsgroup movement commands will work on collections of newsgroups.

This is documented in the Info pages under Gnus/The Group Buffer/Group Topics.

I used to think so, too, but you just follow the directions in the
info and everything works fine.  Follow them by the letter.

I've now added something like this to the Gnus manual.

As someone mentioned about the FSF Emacs bug for 19.30, frankly I never
thought it was located there, colour me embarassed.  Anyways I never
started using gnus-topic until I had version 19.30, my bad.

After using gnus-topic, and trying after 3 abortive attempts to get the
groups just right, I would seem to find some uncanny way of totally erasing
my newsgroups.  And then having some phantom newsgroup pop up time and time
again after I killed them.  On the 4th attempt, I go it jsut right, and
figured out that you can't just cut and paste, you need to T m newsgroup to
the proper topic node (the topical map will not acknowledge a cut and paste
movement as far as the list is concerned).  Okay it works, but is anyone
working on making it a little more user friendly? =)

POP3 function, and user format functions

[d. hall]

-----BEGIN PGP SIGNED MESSAGE-----

the following function i wrote to bypass having to recompile movemail.

(require 'ange-ftp)

(defvar mail-pop-user nil)
(defvar mail-pop-pass nil)
(defvar mail-pop-host "pop")
(defvar mail-pop-spool-file nil)

(defun mail-pop-mail-retrieve ()
  (interactive)
  (let ((user-name (or mail-pop-user
			(user-login-name)))
	 (my-passwd (or mail-pop-pass
			(ange-ftp-read-passwd "Enter your password: ")))
	 (pop-server mail-pop-host)
	 (spool-file (or mail-pop-spool-file
			 (getenv "MAIL")
			 (concat rmail-spool-directory
				 (user-login-name)))))
    (save-excursion
      (generate-new-buffer "*popclient*")
      (call-process "popclient" nil "*popclient*" nil
		    "-3"
		    "-v"
		    "-u" user-name
		    "-p" my-passwd
		    "-o" spool-file
		    pop-server
		    ))))

Now, my other problem.  I emailed the backtrace via gnus-bug (which game a
further error that I had malformed sources in nnmail).

I have a personalized format function for gnus-summary-line-format, which
makes it look more like vm or rmail in display.

(setq gnus-summary-line-format		"%U%R%z%[%-16,16n%]: %uX %I`%s`\n")

(defun gnus-user-format-function-X (header) "\
Return a string like MMM DD LLLL from the header."
  
  (let* ((header-lines (mail-header-lines header))
	 (header-date (mail-header-date header))
	 (date-vector (timezone-parse-date header-date))
	 (date-mon (aref date-vector 1))
	 (date-day (aref date-vector 2))
	 (string-lines (if (> header-lines 9999)
			   "????"
			 (number-to-string header-lines)))
	 (string-mon (or (capitalize 
			  (car (nth 
				(1- (string-to-number date-mon))
				timezone-months-assoc)))
			 "???"))
	 (string-day (or date-day "??")))
    (format "%s %2s %4s" string-mon string-day string-lines)))

If I byte-compile this function w/o first loading Gnus, I get an error the
next time I attempt to run Gnus.  So I have the change the %uX to %d so
Gnus will load and run, and then re-byte-compile the function, and then
change the %d back to %uX and it runs just fine.  Unfortunately I didn't
save the backtrace, but Lars should be seeing a copy of it soon.  It has be
completely baffled.  Am I not loading a file before byte-compiling?  Or is
it another Emacs 19.30.1 bug?
