citation and flow-filling

citation and flow-filling

[Paul Jarc]

When flow-filling an article with quoted material, Gnus treats space
as a non-quote character, even when it is followed by a quote
character (">") and is preceded by only quote characters.  This is
what RFC 2646 says it ought to do, but in practice, it breaks.  Gnus
actually breaks this itself, because when quoting, "> " is prepended
to each line.  If the line already starts with a quoting character,
then only ">" should be prepended.

Can either of these already be configured the way I want them?  I see
message-cite-prefix-regexp, but I don't think it's used for
flow-filling, or citation in replies.  If not, I'd be happy to add the
code, if someone can point me in the right direction.

Also, is there an existing function I can add to message-send-hook or
some such to make my messages format=flowed?

If you want to replace "> > " in multi-level quoting with ">> ", then
may I suggest Trivial Cite (tc.el) which does this?

Thanks.  I'll apply this patch.

Yes, that indeed was my intention.  It seems that in recent CVS
versions of Gnus (as of a couple days ago), the "To Address" and "To
List" "Gnus Customize" variables no longer work.

Any ideas as to why?

I'm manually sending this to the group.

I'm answering my own question: it was due to an error in my
`.gnus.el', which I have now fixed.  "To Address" and "To List" work
just fine.

As Emily Latella would say ... "Never mind".

Yes.  Try attached patch.

I don't think it should be used in flow-filling (it has it's own hard
coded rules to match rfc2646), but the patch below makes use of it
when indenting messages.

Until emacs support visual cues for soft and hard line breaks, I see
little point of adding support for it in Gnus -- I mean, how would you
know if a paragraph contained soft or hard line breaks when you edit
it?

I do find it quite amazing that emacs doesn't support visual cues for
TAB, soft/hard linebreaks etc though.  I mean, I bet even vi supports
this.  (Lete the flame war begin... :-))

Works nicely.  Will this be committed?

Well, I'd like to be able to make Gnus violate 2646 in this way.  I
guess I would have to hack fill-flowed to do this, hm?

I'd be satisfied with something that added a space at the end of each
body line not followed by a blank line, and which added
"Content-Type: text/plain; format=flowed" to the header.

If any part of a message would suffer from this treatment, then I'd
disable the hook entirely for just that message and send it as
format=fixed.

Yes.  If you think it would be useful for others, perhaps you could
submit a patch to make it customizable?

It shouldn't be hard to write a hook and attach it to
`message-send-mail-hook' or something, I think.

Just wanted to say thanks. I've been using the citation patch for a
few days. Nice work!

Other editors also provide editing this kind of file, without any
visual cues.  As an example, see xpostit.
