PGG and 'pgg-sign' command.

PGG and 'pgg-sign' command.

[Jorge Godoy]

Hi!


I'm trying to use 'pgg-sign', but although it makes the screen blink
and repositions the cursor at the beginning of the screen, nothing
happens and the message isn't signed. When I use pgg-sign-region with
a marked region, everything works just fine.

Is there something I can do to try fixing this? I'm not a LISP coder,
so I can only help from the user side of the problem.


Thanks in advance,

Why are you trying to use this function?

Well, what do you want to use it for?  If you just want to sign a
message, use something like mml-secure-sign-pgpmime (C-c C-m s p)

When the message gets processed before sending the secure tag at the
top of the body will get turned into the proper signed parts, etc.

The patch below should fix it, but it is ugly and the same solution
doesn't work for pgg-encrypt.  Elisp Q: How do I interactively call a
function specifying the parameters directly?

Which one? pgg-sign or pgg-sign-region?

I'm trying pgg-sign because the message contains no attachment, only
text, and I want it all signed. It's the fastest way --- theoretically
--- because I don't have to mark any region before applying the
command. 

I'm using pgg-sign-region because it works.

With PGG?

I'm trying it on this message.

I hope so.

I guess that the solution pointed out by Josh Hubber
(<87znsil4pb.fsf@mail.paradoxical.net>) solves the problem and even
make this command useless... I know that you added them because of
some prior message of mine, but what do you think about mapping
'pgg-sign' and 'pgg-encrypt' to those mml- equivalent options?

pgg-encrypt/pgg-decrypt/pgg-sign/pgg-verify should now display output
when called interactively.  I'm not sure they are useless, users that
aren't familiar with Emacs often dislike *-region functions.  And it
saves power users a key press to set the mark too.

I don't think that is a good idea.  PGG should IMHO only be a
low-level interface to OpenPGP implementations such as GnuPG.  If you
need more high-level operations, you can use a more high-level
interface like MML.
