exploring levels 5 and 6 of subscribedness

exploring levels 5 and 6 of subscribedness

[jidanni]

There is
S l	gnus-group-set-current-level
but no
        gnus-group-show-current-level
to show the level of the current group. One must dig it out of
.newsrc.eld here in "Gnus v5.11".
Indeed it would be nice to have a command show all the levels of all
the groups. All there is now is "show me all the groups below a given
level".

You see I have this group, "nnml:archive.2008", at level 5. Quite dim
in colour, but I don't want to see it at all there in the *Group*
buffer. OK, I then set it to level 6. But then it becomes
excruciatingly hard to dig it up when I do want to see it. j
(gnus-group-jump-to-group) then refuses to expand its name, etc. The
whole of gnus practically denies its existence. I never had a daughter
named Martha, etc.

At level 5 I could still mark all the articles as read and then it
acts like I want and goes just below the surface of the *Group*
swimming pool, but there are new articles accruing each day so it
becomes unread.

I'm sure http://jidanni.org/comp/.gnus.el isn't to blame.

Wait,
  L runs the command gnus-group-list-all-groups
  List all newsgroups with level ARG or lower.
  Default is `gnus-level-unsubscribed', which lists all subscribed and most
  unsubscribed groups.
OK, I now set the group to level 6, and gnus-level-unsubscribed is 7, but
the group doesn't show up after hitting L. There I am, a victim of a
*Bug* again. There are even unread articles in the group.

By the way, investigating another function,
  (defun gnus-group-list-groups (&optional level unread lowest)
    "List newsgroups with level LEVEL or lower that have unread articles.
  Default is all subscribed groups.
  If argument UNREAD is non-nil, groups with no unread articles are also
  listed.
You forgot to document LOWEST.

P.S. gnus-level-unsubscribed docstring says
  Groups with levels less than or equal to this variable are unsubscribed.
[add "...EXCEPT:"]
  Groups with levels less than `gnus-level-subscribed', which should be
  less than this variable, are subscribed.
But still this is as confusing as the Info page:
     Gnus considers groups from levels 1 to `gnus-level-subscribed'
  (inclusive) (default 5) to be subscribed, `gnus-level-subscribed'
  (exclusive) and `gnus-level-unsubscribed' (inclusive) (default 7) to be
  unsubscribed...
You probably should just make a table.

There is gnus-group-group-level, but that's not an interactive function for some reason.  A long time ago I had put a wrapper for it in my init.el but it apparently fell out of use because I see I no longer have it there.

You can add %L to the group line format and you'll see it all the time.

There's also A l which will only show groups on a given level.

I don't love the use of colors to distinguish the different levels either.  I customized that out of my way.  But then I'm satisfied with using just three levels, not counting whatever makes a group unsubscribed or killed.  I make 3 my default list level and use 4 for groups like your archive (I don't use 1 - I don't know why, it just turned out that way).

Yup, that unsubscribed doesn't work the way you describe you'd like it to is exactly what drove me to my current scheme.

Setting your default list level lower might solve this, but may require you to reset levels on some groups.

I'm not running that version but I believe you will see the current
level when you hit S l.  I do.  And have for years I think. (Not real
sure on that last... but for a long time anyway)

Of course that only tells you one group at a time.

OK, now after L (gnus-group-list-all-groups), and
(gnus-group-jump-to-group "nnml:archive.2008")
my *Group* buffer is now
6  U  *: debian_bugs_1st           20070907T052611
6  U  *: debian_bugs               20070907T052527
6  U  *: archive.2008              20080121T014905
6  U  *: DebCentral                20060201T132119
6  U  *: /home/jidanni/tmp/THF6A-1 20041127T070706
(gnus-group-line-format: "%L%B%1{%M%}%S%p%P%2y: %(%-50,50G%) %d\n")

But when I hit L again, *poof*, "archive.2008" disappears.

We now look into .newsrc.eld,

  ("nnml:archive.2008" 6
   ((1 . 68))
   ((reply 44 49) (seen (1 . 70))) "nnml:"
   ((timestamp 18323 35217)))

As an experiment we now use gnus-group-catchup-current, giving

  ("nnml:archive.2008" 6
   ((1 . 83))
   ((seen (1 . 83)) (reply 44 49)) "nnml:"
   ((timestamp 18323 61324)))

whereupon L (gnus-group-list-all-groups) returns it to the *Group*
buffer.

Now no matter what level or not, how could a group with no unread
articles appear in the *Group* buffer, while the same group with some
unread articles disappears?

That must be a bug. Mr. Steib had better have a good explanation for this.
