[gnus] Fetch only new news from last visit

[gnus] Fetch only new news from last visit

[Diep Pham]

I'm trying to use gnus to read news from gmane.org. But it is quite
confusing to use.

I subscribed to a group, when I try to access the group, gnus ask me:
"How many articles do you want to ...". I don't think fetch all news is
good idea so I choose 100. I read all news and close gnus. When I open
gnus and try to access the newsgroup again, gnus still ask me "How many
articles do you want to ...". I enter 100 again and endup fetching older
news than the last time I visit the group. So my question:

* is there a way that can prevent fetching older than last visit?
* is there a way to disable the prompt "How many ariticles ..." and just
  fetch all new news like a normal news reader?

C runs the command gnus-group-catchup-current-all (found in
gnus-group-mode-map), which is an interactive compiled Lisp function
in 'gnus-group.el'.

It is bound to C, <menu-bar> <Group> <Catch up all articles>.

(gnus-group-catchup-current-all &optional N)

Mark all articles in current newsgroup as read.
Cross references (Xref: header) of articles are ignored.

You can catch up in that group, that is, mark all articles as 
read. Hit C on the group in the group buffer.

(setq gnus-large-newsgroup nil)

You should be careful with that variable, if you just subscribed 
to a group with a lot of articles, it will take a while to get 
them all. If you encounter that hit C-g, and then C-u followed by 
number of articles that you want and then <enter>. Then you can 
catch up in that group.

There is a "dribble" file which will record everything
you do in a session. When you exit Gnus, Gnus will
write those changes to a newsrc file, so next time you
start Gnus you won't get the articles you already read
(the file is used to record other things as well).

You can follow this process by seeing how articles are
marked as read ("r") in the summary buffer when you
select them for reading.

When you add a new newsgroup, you can hit `c' for
`gnus-group-catchup-current' if you feel like 
starting with new posts only. What happens is the
exact same thing: "Mark all unread articles in the
current newsgroup as read.", as the help puts it.

Note that Gnus might not quit properly, i.e.
the newsrc file might not be updated, if you just shut
down Emacs, so be sure to exit Gnus the proper way
before you do. If you think this should be
automatized, there are many ways to do that; just ask
if need be.

As for disabling the question how many articles to
fetch, you can increase the value of, or set to nil,
the variable `gnus-large-newsgroup'. However, if you
get on with proper usage with read articles not
reappearing, typically this won't be a factor since
most (all?) newsgroups won't have 200 or more new
articles anyway (200 is the default value for
gnus-large-newsgroup). If you still want it, see the
help for that variable.

Good luck!
