gnus-summary-copy-article: choose group based on sender?

[Graham Guttocks]

Greetings,

I gather that `gnus-move-split-methods' is what I need to customize in
order to influence the group name chosen when copying articles.

Does anyone have a definition of `gnus-move-split-methods' which picks
the destination group based on the article's sender? (i.e, LHS of the
e-mail address)

Or, put another way, how do I get access to the sender name from within 
a `gnus-move-split-methods' definition?

It seems that entries like ("^From:.*jrl@" "nnml:to-jrl") might do
the trick.

This isn't dynamic enough. I'd have to have an entry for every
possible sender. I'm looking for something like this:

(".*" "nnml:$SENDER")

Where $SENDER is the LHS of the sender e-mail address. e.g, 
nnml:kai.grossjohann

I know the above syntax isn't right, but hopefully it will
illustrate my point.

I have gnus-move-split-methods set to this:

(((lambda (arg)
    (let ((grp (dsg-get-appropriate-group arg)))
      (cond ((stringp grp)
             (list grp))
            ((listp grp)
             grp)
            t "nnimap+linus:INBOX.in-box")))))

Where arg is the name of the group (I think that's in the info since
it's not in the documentation string).  dsg-get-appropriate-group is
an overly complicated function.  It relies on the fact that the
function is run with current-buffer set to the article (or maybe
original article; I forget).  You don't want my definition of it,
which has a lot of my work stuff hard coded.  It's easy enough to
search for a given header and dynamically return a group name based on
it.  If the group doesn't exist, you will be prompted to create it
when you confirm the copy/move.

Well, this is my question. It's not obvious to me how I would
do this. A documentation pointer would be fine too if such a 
thing exists.

See the function mail-fetch-field to get the value of a given field.
Then use concat to construct a group name based on that value and
return it.

Ugh, I'm really struggling here. This is what I have, but something
isn't quite right:

(setq gnus-move-split-methods
      '((".*" (lambda ()
		(concat "saved." (mail-fetch-field "from"))
		"nnml:"))))

Hm.  First, you concat "saved." and the from header, then you throw
that data away.  Then the function returns the string "nnml:".

Maybe you meant this:

    (concat "saved."
            (mail-fetch-field "from")
            "nnml:")

Suppose the From header is "Kai Grossjohann <kai@frob.org>", then the
above will produce a group name like this:

    saved.Kai Grossjohann <kai@frob.org>nnml:

It looks weird.  There is a function mail-header-parse-address, btw,
such that

    (mail-header-parse-address "Kai Grossjohann <kai@frob.org>")

will return 

    ("kai@frob.org" . "Kai Grossjohann")

which appears somewhat more useful :-)

Does this help?  (Give a man a fish... teach... you know...)

It does help, thanks.  Now the problem is that my News directory is
being prepended to the group name.  For example,

/home/graham/News/nnml:save.kai@frob.org

This is what I have in my .gnus:

(defun sender-save-name (group)
  (concat "nnml:save."
	  (car (mail-header-parse-address 
		(mail-fetch-field "from")))))

(setq gnus-move-split-methods
      '((sender-save-name)))

Why is the News directory even in the picture, and how can I get rid
of it?  I just want the literal "nnml:save.kai@frob.org".

There are variables gnus-split-methods and gnus-move-split-methods,
where the former specifies filenames (for the `o' command, I guess)
and the latter specifies group names (for `B m').

The above behavior could be explained if you have set
gnus-split-methods to a similar value and use `o' or one of the `O'
commands instead of `B m'.

If that wasn't it, I have no idea.

I haven't set gnus-split-methods.  gnus-move-split-methods is set
as shown above.  I'm not using `o' or `O', but rather `B c', and 
I'm still seeing the ~/News directory prepended to the group name.

At this point, it's almost beyond imagination that something this
seemingly simple has consumed so much time and effort.

I'm flabbergasted.

Does anyone have an idea?

The next thing to do would be to find where gnus-move-split-methods
is accessed (or what does gnus-summary-move-article do), then do M-x
edebug-defun RET on that function, then watch it compute the wrong
result.

Reality surpasses our wildest dreams sometimes...

M-x apropos RET fetch-field RET

The docs for gnus-move-split-methods point to gnus-split-methods, and
its docstring has the info.
