Signing message reply problem

Signing message reply problem

[-- Attachment #1: Type: text/plain, Size: 1650 bytes --]

Hello,

I just started experimenting with signing and encrypting mail with
Gnus. For most part is working just fine, but I found a situation that
is giving me trouble. When I get an e-mail from someone who didn't sign
or encrypt their message and then I reply to their mail, I get the
following:

,----
| To: "And <and@XXX.XX>
| Subject: Re: TEST
| From: Angel de Vicente <XXXXXXXXXXXXX>
| Gcc: nnml:Correo.MAIN
| --text follows this line--
| 
| 
| "And <XXXXXXXXX> writes:
| > this message is strictly prohibited. More information:
| >
| <#secure method=pgpmime mode=sign>

`----

In my .emacs file I add the following hook, so that all messages will be
signed automatically:

(add-hook 'message-setup-hook 'mml-secure-message-sign-pgpmime)

and that works fine for regular messages that I start or when replying
to previously signed, but if the message I reply to is not signed, then
the tag <#secure method=pgpmime mode=sign> is placed in the middle of
the message, and the outgoing message is not signed.

I can certainly sign it no problems if I issue the command C-c C-m C-s,
which then positions the tag again at the beginning of the message, but
obviously I would prefer not to do it by hand, because I will most
likely forget.

Any advice/ideas?

Thanks

That sounds like either a bug or a documenation issue, maybe report it
with M-x report-emacs-bug (you didnʼt mention which version of Emacs
youʼre using)

Untested, but something like:

    (defun angel-message-setup ()
        (save-excursion
           (message-goto-body)
           (mml-secure-message-sign-pgpmime)))

    (add-hook 'message-setup-hook 'angel-message-setup)

Emacs version is 28.2. Will report the bug then (I have never used
'report-emacs-bug', I hope it is straightforward).

Thanks, but unfortunately it behaves in the same way.

For someone who already sends mail using Emacs itʼs very easy :-)

Strange, it works for me. If you want to work out whatʼs going on you
can use `edebug-defun' and then single step through
`angel-message-setup' to see whatʼs going on.

It will also make you a better programmer, in unexpected
ways ...

(defun gnus-article-wash-more ()
  (interactive)
  (article-translate-strings
   '(
     ;; ...
     ("ʼ" "'")
     ))
  (gnus-article-strip-multiple-blank-lines) )

(defun gnus-article-prepare-hook-f ()
  (gnus-with-article-buffer
    (gnus-article-wash-more) ))
(add-hook 'gnus-article-prepare-hook #'gnus-article-prepare-hook-f)

Does your terminal not like 'ʼ'?

The apostrophe?

  $ ascii \'
  ASCII 2/7 is decimal 039, hex 27, octal 047, bits 00100111: prints as `''
  Official name: Apostrophe
  Other names: Single Quote, Close Quote, Prime, Tick, Pop, Spark, Glitch, '

On the contrary, it's the prefered one ...

ascii(1), written by Eric Raymond in 1990 BTW ...

You see, your washing has created confusion, because I wrote U+02BC
MODIFIER LETTER APOSTROPHE, not U+0027 APOSTROPHE. But you knew that

Supportet browsers in browse-url.elc

[Alexandros Prekates]

In emacs 27.1 taking a look at the code of  browse-url-default-browser
it seems that it runs through a list of hardcoded options.

So there is a supported list of browsers. 

Is there a certain interface that a browser must have in order
to being supported by browse-url.elc ?

I'm not sure I understand: are you asking what would it take for Emacs to
add yet another browser to the list?  If so, I guess being Free Software is
the only important requirement.

Maybe you were trying 'r' instead of 'R'?

I edebug'ed it and basically it goes through the function, inserts the
tag for signing the message, but afterwards it yanks the text right
after the headers, so pushing down the tag.

Which I think is what you expect from message-setup-hook: "Hook run as
the last thing when the message buffer has been initialized, but before
yanked text is inserted.". Ideally I would like to add the hook after
the yanked text is inserted, but not sure how to proceed..

Cheers,

Right. You might have more luck with `mail-citation-hook' instead.

What does this do in terms of security and what technology is
it we speak of?

Solved by changing it to:
(add-hook 'gnus-message-setup-hook 'mml-secure-message-sign-pgpmime)
