auto-fill in message mode filling with prefix "> "

[-- Attachment #1: Type: text/plain, Size: 770 bytes --]

Hello,

I use emacs snapshot on Debian.  Recently, but cannot say when exactly,
my email composition has started behaving strangely with respect to
auto-fill mode.  Specifically, if I'm responding to an email, as I type,
long lines get auto-filled with "> " as the prefix.  The first line of
the paragraph does *not* start with "> " and I usually have at least one
blank line between the paragraph I am typing and any included text from
the original email.

I have searched my configuration for anything that would affect this but
I have nothing.  When it comes to auto-fill, I've left everything as
default as far as I can tell.

Any suggestions on how to track this down would be welcome.  

Thank you.

There was a thread not too long ago about this, but now I can't for the
life of me find it. I only glanced over the thread (I saw this problem,
too, but only once or twice), but my impression was that someone had
figured it out. I think if you just wait a bit, the fix will come down
to you.

Sorry to be unhelpful...

  http://lists.gnu.org/archive/html/bug-gnu-emacs/2017-12/msg00665.html

(and bug#29767 in general).

And no, I don't think we have a solution for that yet.

I was doubly unhelpful! Thanks for the link.

Thanks; this helps as it does mean I am not going crazy! ;-)

I'll look for it but hopefully somebody will respond here in case I
cannot find it!

Thanks.  This bug is exactly what I am experiencing, including the

Are you able to reproduce this in Emacs started with `emacs -Q`?

That would be challenging.  

In any case, others have pointed me to the bug list for emacs.  It seems
that this is a known bug for which there is not yet a fix:

  https://lists.gnu.org/archive/html/bug-gnu-emacs/2017-12/msg00665.html

Thank you.

Maybe use the old filladapt (worked great on XEmacs) while those bugs
get fixed.

Thanks.  I might do just that.  For the moment, I have turned off
auto-fill and simply fill the paragraphs when I'm done.  Paragraph
filling seems to work just fine.

Emacs filling is different from filladapt in one annoying way, even
running with -Q thus probably not my setup.

If you type something like

line1 word1 word2
  indentedLine2 word1 word2
line3 word1 word2

and then, with the cursor anywhere on line3, invoke fill-paragrah, you
end up with:

line1 word1 word2 indentedLine2 word1 word2 line3 word1 word2

whereas, filladapt leaves it as displayed.  And yes, emacs auto-fill
also doesn't handle line tags properly.

I'm using Emacs25 and Emacs-Snapshot on Debian. My emacs init loads
'Trivial Cite' (TC), and I do *not* experience this issue.

TC is in Debian's emacs-goodies-el. Perhaps a comparison of TC and the
Emacs efault will turn up a clue.

Thanks for this.

But interestingly enough, emacs-goodies-el started failing on
installation (via apt) with more recent emacs snapshots.  Trying just
now gives me lots of warnings but more importantly some errors:

filladapt.el:79:1:Error: Loading ‘nil’: old-style backquotes detected!
framepop.el:774:1:Error: Loading ‘nil’: old-style backquotes detected!
highlight-current-line.el:188:1:Error: Loading ‘nil’: old-style backquotes detected!
xrdb-mode.el:179:1:Error: Loading ‘nil’: old-style backquotes detected!

This is with emacs snapshot version 2:20171231 on buster.

The same package compiles fine with emacs25 however.

On my emacs 25.3.1, filladapt.el complains of the backquotes problem,
but compiles (after I fix another small problem, elsewhere) and seems to
run.

Don't know enough elisp to fully replace the `, construct here
  (defmacro defcustom (var value doc &rest args) 
     (` (defvar (, var) (, value) (, doc))))))
with non-deprecated code.

This is actually simple - you don't need to know lisp.

Replace (` x) with `x.
Replace (, y) with ,y.

So that entire last line should become:

    `(defvar ,var ,value ,doc))))

If you want indented paragraphs then you can use
paragraph-indent-text-mode or paragraph-indent-minor-mode.  That will
make fill-paragraph behave itself in this case.

However, AFAIK, out-of-the-box Emacs provides no way to deal with both
types of paragraphs in one buffer.  You have to pick either space
separated paragraphs or indented paragraphs.

Ha! It's the parenthesis that are being deprecated:-)
Filladapt.el now compiles with no warnings.

Thanks for the pointers, though I guess I'll keep using filladapt.

Here [1] is how I do it.

Some of the stuff (lines 1-2) in the hook
in unrelated.

(defun gnus-article-fill-cited-article-keep-point ()
  "Fill the article and restore point."
  (interactive)
  (save-excursion (gnus-article-fill-cited-article)) )

(defun gnus-article-show-filled-citation ()
  "Fill the citation opened on a hidden-citation-button-press."

  (let*((pos    (point))
        (button (get-char-property pos 'button)) )
    (when button
      (widget-button-press pos)
      (gnus-article-fill-cited-article-keep-point) )))

For this particular case, the right fix is to remove the whole (defmacro
...) since it's only there for compatibility with versions of Emacs that
don't have `defcustom`.  This macro was introduced in Emacs-19 or
Emacs-20, can't remember which but it's highly unlikely that you still
have such an Emacs on your machine.

Most likely. Looking closer at it the defmacro is part of an
eval-and-compile preceded by the comment:

  ;; BLOB to make custom stuff work even without customize

I'll comment out the whole eval-and-compile.

BTW, maybe we could put filladapt into GNU ELPA.
I think we pretty much have the legal paperwork already.
It'd be good to get Kyle's agreement by email, tho.
