Gnus: moving to the latest article in a thread

Gnus: moving to the latest article in a thread

[Francis Moreau]

Hello,

I'm looking for a magic thread command which allows me to go to latest
article in the current thread.

It would be really cool if that command understand numeric prefix, so
giving '2' as prefix would move the second most recent article.

Thanks

Something like `9999 T d'?

,----[ (info "(gnus)Thread Commands") ]
| `T d'
|      Descend the thread (`gnus-summary-down-thread').
| 
| `T u'
|      Ascend the thread (`gnus-summary-up-thread').
`----

(defun rs-gnus-summary-down-thread-max (&optional back)
  "Go to the lastest article in the current thread.
With prefix, go up BACK articles from the lastest."
  (interactive "P")
  (while (/= 1 (gnus-summary-down-thread 1))
    t)
  (gnus-message 7 "End of thread reached.")
  (when back
    (gnus-summary-up-thread back)
    (gnus-message 7 "Went back %d articles." back))
  (gnus-summary-show-article))

Bye, Reiner.

Hmm, yes that would work if inside the thread, sub thread are sorted
by date, I didn't think about this before.

But if they're not, the only way to do that is to keep a list of all
articles in the thread and to sort this list by date (most recent
first). So that last article is the first article in the list
etc... the prefix would be just the index in the list.

thanks for your function.

I am interested in the requirement here. Do you really go to the last
article in a thread? If so, a natural "first step" in reading a thread?
Would you really order a thread so latest article is first? It strikes
me as very unusual behaviour :-; Still, the wonderful Gnus can be
moulded to all tastes.

Well consider you have the following thread:

  o
  +->
   |  +->
   |     +->
   |
   +->
      +->
         +->
          |
         +->
            +->
                ....
                   +->  <latest article>

And you want to reply to the latest article. How do you move to it ?
Of course you can move to it with various thread commands but not in
one shot.

> Still, the wonderful Gnus can be moulded to all tastes.

yes that's true, one thing that makes me still using gnus. Although
I don't speak elisp yet ;)

 But it has a high priority in my todo list.

Well, true, but normally one reads all (non filtered) replies in a
thread before replying to a last one - otherwise you might be rehashing
previous replies.

It's strange. I just cant visualise a need to go to last post regardless
of the content of the previous ones in order to reply. If one wanted to
reply then presumably one had already read it in which case you are
already on that article. Still, if we all worked the same way life would
be pretty boring.

It does help. I have a little and it can be very useful of course!

It just mean that I read the whole thing, then digest what I just
read, do some boring work, oh dear it's high time to lunch. Several
hours may past, then I suddenly have time to replies to the thread. So
now I just want to go to the latest one without searching for it (that
can be quite annoying when the thread is big).

And potentially more annoying to others if you then reply to the last
one which is now 20 replies later than the last one you read.

(defun rs-gnus-summary-down-thread-max (&optional back)
  "Go to the lastest article in the current thread and show article.
With prefix, go up BACK articles from the lastest."
  (interactive "P")
  (gnus-summary-show-thread)
  (while (/= 1 (gnus-summary-down-thread 1))
    t)
  (gnus-message 7 "End of thread reached.")
  (when back
    (gnus-summary-up-thread back)
    (gnus-message 7 "Went back %d articles." back))
  (gnus-summary-show-article))

--8<---------------cut here---------------end--------------->8---

If the thread is hidden, an endless loop happens. Therefore i have added
(gnus-summary-show-thread) to show the thread first.
