When using nnir for search results there are nnir-specific bits of
information that are of potential interest: the retrieval score (RSV) of the
article (some search engines, such as gmane, report a match "score";
others, such as imap, just give all results an arbitrary score of
"100"); and the original group the article belongs to.
Historically (which means "up till now") nnir has done this by mangling
the subject header of each article to incorporate this info; then when
the article subject is displayed in the summary buffer the info shows
up. This is bad for a couple of reasons: some things, notably the
registry, care about the original subject so the mangling has to be
accounted for; and it should really be up to the user what information
is displayed in summary-buffer lines (with a sensible default).
A (mostly) straightforward way to handle this is to use the
gnus-summary-line-format. I would like to add a couple of specs to
gnus-summary-line-format-alist to do this (tentatively %Z for the RSV
and %G for the full group name and %g for the short name). I'd then
introduce nnir-summary-line-format which is used locally in nnir summary
buffers rather than gnus-summary-line-format (set through a hook).
Does this sound OK?

Sounds like a very good idea to me. :-)

OK, just pushed this change. Set nnir-summary-line-format to whatever; a
nil value (the default) will use gnus-summary-line-format instead.
In case anyone is interested my overly complex value is
"%15{%U%}%15{│ %}%12{%-10&user-date;%}%15{ │%}%12{ %}%(%-18,18f%)%12{ %}%*%7{%B%}%«%14{%~(ignore 0)Z %}%11{%s%} %14{%g%}%»\n"
Cheers,
Andy

Currently nnir- macros used in `gnus-summary-line-format-alist'
will never be expanded. For instance:
(assq ?Z gnus-summary-line-format-alist)
=> (90 (or (nnir-article-rsv (aref gnus-tmp-header 0)) 0) 100)
But it seems to have to be:
=> (90 (or (elt (if (> (aref gnus-tmp-header 0) 0) (progn (elt nnir-artlist (1- (aref gnus-tmp-header 0))))) 2) 0) 100)
To make it do that, those macros have to be loaded before gnus-sum,
however nnir requires gnus-sum in it.

Does it solve?

Ah, good catch. I think it works without expanding the macro (at least
it seems to be working for me) but it should probably be fixed to that
the macro is properly expanded. I'll think on it.
Best,
Andy

Hi Katsumi:
I'm just learning about this stuff so I wanted to ask if this is the
right way to handle it:
I've added autoloads to gnus-sum:
(autoload 'nnir-article-rsv "nnir" nil nil 'macro)
(autoload 'nnir-article-group "nnir" nil nil 'macro)
and I've rearranged the order of things in nnir.el so the macro
definitions come before the (require 'gnus-sum).
After doing this (and byte compiling and starting fresh) I have
(assq ?Z gnus-summary-line-format-alist)
(90 (or (elt (if ... ...) 2) 0) 100)
which looks good (the macro is fully expanded). And no warnings during
byte-compilation.
Does this all sound right? If so, I'll push the change.
Best,
Andy

I think it's definitely right. Thanks.
