gnus request scan issue : backtrace

[Richard Riley]

trying to localise spam splitting to only my main imap server I
modified my imap select method to this:-

      (setq nnimap-split-fancy (quote (: spam-split)))

      (add-to-list 'gnus-secondary-select-methods
                   `(nnimap "riley"
                            (nnimap-address "offlineimap")
                            (nnir-search-engine imap)
                            (nnimap-stream network)
                            (nnimap-split-methods (quote nnimap-split-fancy))
                            ))


Starting gnus I then get this backtrace:-

Debugger entered--Lisp error: (wrong-type-argument sequencep quote)

Is there anything obviously incorrect about this? And if this is a
valid "error" how would I go about cleaning up my email to avoid it?

(This is a very common confusion when you're learning ELisp.  It took me
a while too.)

(quote x) and 'x are usually the same thing in ELisp.  You don't want to
quote inside a quoted expression:

(setq nnimap-split-fancy (quote (: spam-split)))

(add-to-list 'gnus-secondary-select-methods
             `(nnimap "riley"
                      (nnimap-address "offlineimap")
                      (nnir-search-engine imap)
                      (nnimap-stream network)
                      (nnimap-split-methods nnimap-split-fancy)
                      ))

What you had before was "set the nnimap-split-method to the list of the
symbol 'quote followed by the symbol 'nnimap-split-fancy".

Doing that results in

nnmail-check-duplication: Wrong type argument: listp, nnimap-split-fancy

Could you give a backtrace please?

That should probably be nnmail-split-fancy, or a fancy split
directly...

Right.  So many nn????-*-* strings...

Richard: if that's set to nnimap-split-fancy, then nnimap-split-fancy
must be a function as in my example.  I'll update my splitting example
and post it here again when I can.

FWIW, I'm using a setup like:

(setq gnus-secondary-select-methods '((nnimap "foo"
                                       (nnimap-address "foo")
                                       ;; etc
                                       (nnimap-split-methods default))))

(setq nnmail-split-methods 'nnmail-split-fancy)
(setq nnmail-split-fancy
   '(|
     ;; to boot, I don't like duplicates:
     ("Gnus-Warning" "This is a duplicate" "mail.spam.duplicates")
     ;; etc
     ("List-ID" "ding\\.gnus\\.org" "mail.app.emacs.gnus")
     ;; etc
     ;; by default we do not trust the rest
     "mail.personal.misc"))

Best regards

And you don't need the backquote if you don't use , and ,@.  A normal
quote will do as well.

I didn't see that, thanks!

Richard: backquotes are special.  Using them indicates you want to
interpolate inside the expression.  For example:

(setq a 4)

'(a) => (a)

`(,a) => (4)

`(,(format "hello #%s" a)) => ("hello #4")

So you want to avoid them unless you're sure you need them.  See 
(info "(elisp) Backquote") for more.

This has changed then? I posted my nnimap-splt-fancy in the op.

   (setq nnimap-split-fancy (quote (: spam-split)))

I wont pretend not to be confused now ;)
