summary buffer format for archives

summary buffer format for archives

[Richard G Riley]

How can I change the summary buffer format for only my archive groups?
e.g I want to see the "to" address rather than the "from address" for
all outgoing emails I have archived.

To answer my own question:

(setq
 gnus-parameters
 '(("^\\(nnimap\\|nnfolder\\|nnml\\)"
    (gnus-summary-line-format "%-23,23~(form (gnus-extra-header 'To))@  %S\n"))))

I'm not sure I understand the manual when it says %f is the "from" or
the "to" field.

Another possibility is to set gnus-ignored-from-addresses to something
that matches your own addresses:

,----[ C-h v gnus-ignored-from-addresses RET ]
| `gnus-ignored-from-addresses' is a variable declared in Lisp.
|   -- loaded from "gnus-sum"
| 
| Value: "\\(asjo\\|adam\\)@\\(koldfront.dk\\|asjo.org\\)"
| 
| Documentation:
| *From headers that may be suppressed in favor of To headers.
| This can be a regexp or a list of regexps.
`----

(This functionality perhaps also accounts for the description of %f that
was confusing to you?)

It means that it's normally the from unless it's a message sent by you.
In that case it's something like

    -> to@foobar.invalid

or

    => news.group.you.posted.in

Hmm, that was not my observation. Possibly something not right as a
result of posting-styles? I should look into it.

Adam's points clarified it for me though:

It did indeed! Thanks.

And combining the two It's much better as the default summary line is
good to go then:

,----
| (setq
|   gnus-parameters
|   '(("^\\(nnimap\\|nnfolder\\|nnml\\)"
|     (gnus-ignored-from-addresses ".*riley.*"))))
`----

This I still see my own name in threads in nntp groups but the "to" in
the archived folders - perfect!

Many thanks to you and Tassilo.

This plays together with ignored from addresses.  See the manual:

,----[ (info "(gnus)To From Newsgroups") ]
|   3. The `gnus-ignored-from-addresses' variable says when the `%f'
|      summary line spec returns the `To', `Newsreader' or `From' header.
|      If this regexp matches the contents of the `From' header, the
|      value of the `To' or `Newsreader' headers are used instead.
| 
|      To distinguish regular articles from those where the `From' field
|      has been swapped, a string is prefixed to the `To' or `Newsgroups'
|      header in the summary line.  By default the string is `-> ' for
|      `To' and `=> ' for `Newsgroups', you can customize these strings
|      with `gnus-summary-to-prefix' and `gnus-summary-newsgroup-prefix'.

Carrying on from this I had hoped

,----
| (setq gnus-group-line-format "%M\%S\%p\%P\%5y: %(%-40,40g%) %ud\n")
| 
| (setq
|   gnus-parameters
|   '(
|     ("^\\(nnimap\\|nnfolder\\|nnml\\)"
|      (gnus-ignored-from-addresses ".*riley.*")
|      (gnus-group-line-format "%G %ud\n")
|      )
|     )
| )
`----

Would give me a group specific gnus-group-line-format.

It doesn't. Any ideas on how I would do that?

Well, I managed it!

,----
| (setq gnus-group-line-format "%M\%S\%p\%P\%uy%(%-40,40g%) %ud\n")
| 
| 
| (defun gnus-user-format-function-y (headers)
|   (if (string-match "^nnfolder" gnus-tmp-group) 
|       ""
|       (concat gnus-tmp-number-of-unread "-")
|     )
|   )
`----

Where are the parameters available inside the format functions documented?

                                    ^  ^  ^  ^
For what are those backslashes?  They seem to cause no harm (because
"\%" is no control character, I guess), but they're not needed anyway.

Gnus parameters take effect when entering a group, so you can set
different summary line formats there.  In the *Group* buffer they don't
have an effect, AFAIK.

No, sorry.

I meant inside the format functions (elisp) as in the function I posted
in the article you replied to e.g:

,----
| 
| ,----
| | (setq gnus-group-line-format "%M\%S\%p\%P\%uy%(%-40,40g%) %ud\n")
| | 
| | 
| | (defun gnus-user-format-function-y (headers)
| |   (if (string-match "^nnfolder" gnus-tmp-group) 
| |       ""
| |       (concat gnus-tmp-number-of-unread "-")
| |     )
| |   )
| `----
`----

How does one get to know which functions/variables are available inside
gnus-user-format-function-y? Here in this case I kept googling until I
found sample functions to discover the existence of
gnus-tmp-number-of-unread. Is there some kind of dynymic/info way to
find out all available "locals". (I'm not really an elisp programmer so
anything I do tends to be cobbled together from other examples).

(I was aware of the format specifiers as they were relatively easy to locate in
the info file.)

I guess I'm probably asking for a quick tutorial in how to figure out
what's there for these things from browsing existing elisp on the
running system. And while I'm at it, every example user defined format
function I have seen ignores "headers" or whatever the parameter passed
in to it is named.
