Hi all,
I'm reading quite a few high-traffic mailing lists, and my mailbox is
shortly before running out of space. So I want to do some expiry.
Basically, I could use total-expire, say, after 365 days, but I'd prefer
if I could expire threads I'm not interested in much earlier than
threads that are interesting to me.
So now I'm trying to write a command that walks over all threads in the
current summary and marks all threads that have a score lower than -30
and whose most recent article is older than 60 days as expirable.
That's what I came up with so far.
--8<---------------cut here---------------start------------->8---
(defun th-gnus-summary-exprire-old-lowscore-articles ()
(interactive)
(goto-char (point-min))
(dolist (thread gnus-newsgroup-threads)
(let ((score (gnus-thread-total-score thread))
(age (/ (- (gnus-float-time (current-time))
(gnus-thread-latest-date thread))
60 ;; minutes
60 ;; hours
24 ;; days
)))
(message "Thread %s has score %s and is %s days old."
(aref (car thread) 1)
score age)
;; (when (and (> age 60)
;; (< score -30))
;; (dolist (article thread)
;; (gnus-summary-mark-article (aref article 0) gnus-expirable-mark)))
)))
--8<---------------cut here---------------end--------------->8---
The problem is that in some summary buffers, I get an error when I run it:
--8<---------------cut here---------------start------------->8---

This seems to happen when there's an incomplete thread. At least the
command doesn't error after I've referred the complete thread using A T.
On the other hand, when I open a summary of another group where also
incomplete threads are shown, I don't get that error.
Hm, it seems that it's caused by the thread having a false root. That
is, the error appears when the thread looks like
--8<---------------cut here---------------start------------->8---
O ┃ +┃Marko Topolnik ┃ ○ Re: nREPL instance started...
O ┃ +┃Marko Topolnik ┃ ╰─❯ <February 15>
--8<---------------cut here---------------end--------------->8---
but when I hit ^ and it becomes
--8<---------------cut here---------------start------------->8---
R ┃ ┃Keith Irwin ┃ ● Re: nREPL instance started...
R ┃ +┃Marko Topolnik ┃ ├─❯ <February 15>
O ┃ +┃Marko Topolnik ┃ ╰─❯ <February 15>
--8<---------------cut here---------------end--------------->8---
my command works without any error.
How can I fix this? I mean, I obviously want to run my command in
complete summary containing all articles I've ever received in that
group. Of course, chances are high that the group contains incomplete
threads with false roots where ^ (gnus-summary-refer-parent-article)
won't cure the symptoms.

It's highly unlikely that I'm actually going to be able to help you with
this, but in trying to write functions that run over *all* the messages
in a group I've usually had to start them like this:
(defun th-gnus-summary-exprire-old-lowscore-articles (group)
(interactive (list (gnus-group-group-name)))
(let ((gnus-large-newsgroup nil))
(gnus-summary-read-group group t t nil)
That at least ensures that all the available messages are present in the
*Summary* buffer.
To be honest I haven't had much luck manipulating Gnus
programmatically...

I'm afraid, that doesn't help, because "all available messages" doesn't
equal "there are no false roots in threads", and those seem to be the
culprit for my code. :-(
But still, I can use your code in order to run my command from *Group*
instead of summary...
Thanks,

Some sort of a "hacking gnus" page on the emacs wiki sometimes seems
like a good idea.

It's nice to have a conversation anyway. :-)

Yes, or even better, (info "(gnus)Gnus Reference Guide") could be
extended.

Oh man, I wish I'd found that section of the manual earlier! That could
have saved me quite a bit of time.
What I'd really like to be able to do is edit a message's headers and
resave it from a lisp program...
