mailcrypt

mailcrypt

[Phil Humpherys]

I use PGP 5.0, and downloaded the latest mailcrypt for PGP 5.0.
I compiled it, placed the .el and .elc files in my ~/emacs
directory where my .emacs loads them.  I have the following in my
.emacs as per the documentation:

(autoload 'mc-setversion "mailcrypt" "Select PGP version" t)
(mc-setversion "5.0") ;; Alternately, "2.6"
(add-hook 'gnus-summary-mode-hook 'mc-install-read-mode)
(add-hook 'news-reply-mode-hook 'mc-install-write-mode)

So, when I text in a buffer that I try to encrypt, I do C-c / s,
and it just beeps and does nothing...  I'm close, but need some
help...  anyone?

Uhm...  I sorta changed gnus-article-hide-pgp to actually delete the
PGP stuff instead of hiding it.  (This made it much, much easier to do
other things with the article buffer, like applying PGP-signed
patches, which was difficult before.)  I was afraid it would break
Mailcrypt, but fixing this in Mailcrypt should be trivial -- it just
has to peek into gnus-original-article-buffer instead of
gnus-article-buffer.

But if this is a major hassle, I can go back to the old behavior...

Actually other washing can cause trouble anyway.

Indeed.  I thought I'd sent this off, but it doesn't look as though I
did.  The patch is against 3.5b4 but was essentially the same for 3.4.
(IIRC it was at Toby Speight's suggestion, to cope with ^Ls before his
sig.)

OK, I missed the point that we were comparing two byte-compiled versions.
I thought that our national Rat was saying that it would not have worked
in source form.  My surprise and question came from there... :-)

I think he was implying that if you're running byte-compiled code it
must be byte-compiled for the correct version of Emacs that you are
using, ie you can't run a PGP compiled for emacs 19.34 with say emacs
20.3, or something to that effect rather than it being a byte-compiled
versus source issue.

I believe the problem with mailcrypt is that it uses some 'internal'
functions to Gnus that are macros, so the do not play well when switching
from version to version (of Gnus).

I don't know why you have to recompile for Emacs->XEmacs other than the
obvious mule stuff.

Seems like it had been byte-compiled with GNU Emacs.  In this case, it 
may not run within XEmacs.

How could it make such a difference?  I thought that running byte-compiled or
not should not make a difference, or else, I would see a bug.  Don't you?

For mailcrypt-3.5b5, I did:

./configure 
make EMACS=xemacs
make install EMACS=xemacs

On that last one, I get this:

/usr/bin/install: mc-pgp5.elc: No such file or directory
/usr/bin/install: expect.elc: No such file or directory

That looks like a problem....  any ideas?

[Phil Humpherys]

I have PGP 5.0, and had mailcrypt working fine under emacs, but
when I went to xemacs (20.4), I get an error message when I fire
up emacs that states that it can't set version 5.0.

When compiling, I did 'make install EMACS=xemacs' as per the
instructions...

Any thoughts?

Have you applied Dave Love's patch to Mailcrypt that was posted here

mailcrypt

[Phil Humpherys]

I'm still having trouble getting mailcrypt to work...  here's
what I have in .emacs:

[phumpherys@swansong humphery]$ grep mc .emacs
(autoload 'mc-setversion "mailcrypt" "Select PGP version" t)
(mc-setversion "5.0") ;; Alternately, "2.6"
(add-hook 'gnus-summary-mode-hook 'mc-install-read-mode)
(add-hook 'news-reply-mode-hook 'mc-install-write-mode)
;(autoload 'mc-encrypt-message "mailcrypt" nil t)
;(autoload 'mc-sign-message "mailcrypt" nil t)
;(autoload 'mc-insert-public-key "mailcrypt" nil t)
;(defun mc-install-write-mode ()
;      (mc-create-write-menu-bar))
;  (local-set-key "\C-ce" 'mc-encrypt-message)
;  (local-set-key "\C-cs" 'mc-sign-message)
;  (local-set-key "\C-ca" 'mc-insert-public-key))

I've tried all kinds of permutations of commenting and
uncommenting these lines.  I start a gnus compose buffer, try C-c
e, and it beeps and nothing happens.  What am I missing??
