patches add variable `gnus-confirm-mail-reply-to-news'

[Benjamin Rutt]

[-- Attachment #1: Type: text/plain, Size: 1194 bytes --]

Attached are two patches against today's CVS.  They implement a
feature that lets a user enable an option which will require
confirmation before allowing a mail reply to a usenet article.  This
will help users catch their mistake when they accidently press 'R' to
respond to a usenet article when they really meant to press 'F'.
(FWIW, these patches are inspired by this month's gnu.emacs.gnus
thread rooted by message id <7w4rhgb773.fsf@i19.ruc.dk>).

The first patch is to gnus-msg.el.  For readers of this patch:  I only
added the lines

  ;; Allow user to require confirmation before replying by mail to the
  ;; author of a news article.
  (when (or (not (gnus-news-group-p gnus-newsgroup-name))
	    (not gnus-confirm-mail-reply-to-news)
	    (y-or-n-p "Really reply by mail to article author? "))

to the method `gnus-summary-reply', however adding the 'when' at the
top required that the rest of the function be reindented, so the patch
is a little harder to read than normal because of the reindents.

The second patch is to gnus.texi and is pretty straightforward.

Comments welcome.  If someone would like to commit this, please go
ahead as I've signed papers.  Thanks,

This is likely to be annoying.  Can we perhaps use this case to test 
implementing a "Do not ask me again" option?  Bound to ! perhaps?  
Answering ! to the query would customize-save the variable to nil so the 
user won't see the query again.  What do people think?

Note that the "ask me" option is off by default.  So there is little
potential for annoying.

Oops, I didn't read it carefully.  What about making the default to on
then, and allow the user to never be queried about it in the future
("Don't ask me again")?  People who usually never R to usenet posts
might find the question useful, and leave it enabled, and other people
are only annoyed once.

This sounds reasonable.  I'm not exactly sure how to implement this
though.  It reminds me of back when I first used `narrow-to-region'
and it asked me whether I wanted to enable the command permanently.
It doesn't look like I could directly apply novice.el's enable-command
etc. to do this, since there's no command in this case.  (I don't
think we'd want to require confirmation to simply run
gnus-summary-reply).

Maybe the variable `gnus-confirm-mail-reply-to-news' should default to
'ask.  Then, whenever the variable is used, if it has the value 'ask,
then you pose the question "Don't ask me again?" as you suggested.  If
it has the value nil or t, then just use it.

Does anyone know how to use customize to programmatically set a value
and then make it permanent (i.e. save it to the user's `custom-file')?
I think that would be the best approach to take.

Never mind, I just found `customize-save-variable'.

I think setting default behavior that discourages people from taking
things to e-mail from Usenet discussions is a bad idea.  There are
different cultures in different groups, but more often than not this is
something that people are *encouraged* to do unless they're pretty sure
the whole group would be interested.

I agree. Ok, I added the original patch that defaults to not asking.  Thanks.

I agree also, now I can stop working on that y/n/! confirm feature.
:-)  Thanks for adding the patch.

I used to have this in my .gnus for ages:

(setq rs-mailing-lists "list\\.")

;; Patric Mueller in <7iq1t9.m63.ln@bhaak.xodox.com>
;; von mir erweitert um die Abfrage auf Mailinglisten 
(defadvice gnus-summary-reply (around reply-in-news activate)

		     gnus-newsgroup-name
		     ))
		  (string-match rs-mailing-lists gnus-newsgroup-name)))
	 (y-or-n-p "Really, really reply? "))
    ad-do-it))

It adds "support" for virtual groups that contain newsgroups and for
user defined lists (all of my mailing lists) where I usually don't
want to say `R'.

Would it be useful to be added to Gnus or is it too specifically
tailored for my personal needs?

Cheers, Ray

I didn't test this, but it should add support for setting the variable
to a string or function to get the behaviour you want.  Does it work?

This kind of works for news groups but it doesn't for mail because
(gnus-news-group-p gnus-newsgroup-name) is always nil then.  As I
treat mailing lists like news groups regarding personal replies, the
only way to solve this is to disable this condition.  What about
another variable like `gnus-confirm-treat-mail-like-news'?
