Primary select method switch

Primary select method switch

[Didier Verna]

  Hello,

for several decades, I had an nntp select method as the primary one. Now
the server is dead and I wanted to make my gmail account the main one.
So I (naively) set gnus-select-method to the nnimap server, removed it
from gnus-secondary-select-methods, and restarted Gnus.

Now I have all my gmail groups duplicated. The old ones (named
nnimap+gmail:***) with all their marks are still here, but for each one,
I now also have a *** (no prefix) one, without any marks.

Is there a way to recover from this mess ?

Thank you !

I'm not sure, what I would try is setting:

  (setq gnus-select-method '(nnnil))

and then keeping it that way, so every method is secondary and
prefixed, and no method is special (primary).

That's what I have been doing for decades :-)


  Best regards,

Depends a bit on what you want.  One big difference between primary and
secondary is the prefixing (as you  discovered). Mostly there isn't much
reason to have a primary select method. A common configuration is to
eliminate the primary, and then put everything in secondary. To
eliminate the primary just set it to 'nnil:

     (setq gnus-select-method '(nnnil ""))


You should be able to do this (and put your gmail groups back in
secondary) and remove the unwanted unprefixed (i.e. primary) groups.

Yeah, "total fails" like this are commonplace.  It's what happens when
your mail reader is the culmination of thirty years of cruft.  The
"wut?" of adding a secondary "select methods" variable instead of
vectorizing the first is what you did as a 22-yo in the 1990s.  To this
day I've only a vague idea of what a "select method" is, and I probably
spent more time rewriting gnus than anyone here.

Gnus's persistence model is and was 1990s flat files.  We didn't think
too hard at that time.  If something went wrong, we just went into our
.newsrc.eld, intuited its layout, deleted the offending entries, and
restarted.  I'd advise the same in 2023.

  I've restored everything back to a previous state and did that. Much
  simpler, thanks.

Sorry if I'm missing the obvious, but is it possible to adjust the
prefix shown in the Group buffer with this setup?  Say, I want to have
my local nntp server in secondary, but don't want to see the
'nntp+localhost' prefix all over the place?

Best, Arash

Yes, the server name is used as the prefix - for example I have these:

,----[ C-h v gnus-secondary-select-methods RET ]
|
| Value:
| ((nnml "" (gnus-search-engine gnus-search-notmuch))
|  (nntp "gm" (nntp-address "news.gmane.io"))
|  (nntp "fb" (nntp-open-connection-function nntp-open-tls-stream)
|        (nntp-port-number 563) (nntp-address "feedbase.org"))
|    ...
`----

which gives me names in the *Group* buffer like this:

  nnml:normal
  nntp+gm:gmane.emacs.gnus.general
  nntp+fb:feedbase.news.songkick.copenhagen

(The nntp-address defaults to the server name, so when shortening it I
had to explicitly set nntp-address.)

And this archive method:

,----[ C-h v gnus-message-archive-method RET ]

| (nnml "archive" (nnml-directory "~/Mail/archive")
|       (nnml-active-file "~/Mail/archive/active")
|       (nnml-get-new-mail nil) (gnus-search-engine gnus-search-notmuch)
|       (nnml-inhibit-expiry t))
|
`----

so I have archive groups like:

  nnml+archive:mail-2023
  nnml+archive:news-2023

Adam has given you one answer.

An alternative is to change/customise how each individual group is
displayed in the Group buffer by setting the "comment" attribute.  Check
out "G c" and look for the comment entry.  I've renamed almost all of my
groups.

Ah, cool, I didn't know you could do that!

Even after 20+ years there are still things to learn.

Did you also change gnus-group-line-format or similar for this to work?

Ah, good point.  I have so many settings for gnus, and so many that were
actually incorporated possibly decades ago, that I forget.  Yes, I have

(setq gnus-group-line-format "%m%B%S%p%5y %(%-20C%) %3{%42G [%1L]%}\n")

I guess the important entry is %C which is the "Group comment (string)"
according to the description of gnus-group-line-format.  And, note, I
have the full group name also displayed to the far right.

Thank you,
eric

Yeah, me too, both in gnus and Emacs more generally.  Keeps the level of
interest high!

Could you share an example of what that looks like?



My Group buffer has tens of  "nnimap+servername:INBOX.folder"  and
"nntp+news.gmane.io", "nntp+news.gmane.io"

Just an FYI you might try simply replacing the %g spec in
'gnus-group-line-format with %G. This should display the group name
without the unwanted prefix.
