How to fetch already read articles into summary buffer in gnus?

Question

While in summary buffer how can I make gnus fetching already read articles in two situations:

1. while in a thread with some articles already read (and thus not visible). I would like to complete the thread with all the articles (not only parents!) read or unread.

2. fetch last N read articles which are not visible.

Thanks a ton!

This is definitely not a programming question, so belongs on Super User. @VitoshKa: don't repost your question, it will be migrated automatically once enough people vote to migrate. – Fredkin

oh, sorry I was not aware of the feature. – Holtz

Answer 1

In the summary buffer, to fetch the parent, use ^ (gnus-summary-refer-parent-article) (also available as <menu-bar> <Article> <Fetch parent of article>).

To fetch the whole thread (at least the part that's still on your server), use A T (gnus-summary-refer-thread) (<menu-bar> <Article> <Fetch current thread>).

To fetch more articles, use / o (gnus-summary-insert-old-articles) (also available as <menu-bar> <Gnus> <See old articles>).

Oh, thanks. It was exactly what I needed. A good lesson to look into menus for the feature. I was completely ignoring them; such a bad habit:) – Holtz

Answer 2

For the first question, try

(setq gnus-fetch-old-headers 'some) 

in your .gnus

for the second, when you select the group, it should ask you how many old articles you want to fetch. Does that not work?

I needed those actions after entering the summary buffer. Gilles pointed out the solution. Thanks for the answer anyway. – Holtz

Answer 3

(defun codefalling/gnus-show-all ()
  "Show all mail"
  (interactive)
  (gnus-summary-insert-old-articles t) ;; show all, or t->50 to show 50 old mail
  (goto-char (point-min)))

(add-hook 'gnus-summary-mode-hook '(lambda () (run-with-idle-timer 0.1 nil 'codefalling/gnus-show-all)))

Then gnus will show all mail read or unread.

You have a more elegant way to do so: (add-hook 'gnus-summary-prepared-hook 'gnus-summary-insert-old-articles). Because "run-with-idle-timer 0.1 nil" is the necessary time for the relevant functions to load, and gnus-summary-prepared-hook is exactly the hook to indicate that this task is done. After that, gnus-summary-insert-old-articles would not show the wrong number-p error. – Robtrobust

Answer 4

While ^ and / o commands already mentioned this one useful for debugging: M-^ (gnus-summary-refer-article) when you work with message pain text (which you can get by C-u g).

gnus-summary-refer-parent-article internally used gnus-summary-refer-article...
