error with Group parameter display

error with Group parameter display

[Martin Monsorno]

Hi,

I have the following wonderful setting in the 'Group parameters' for
one group
    (display . [not expire])

which works quite well, but only if I do not have any ticked articles
in that group. In that case only these are shown if I enter the group,
but no unticked read articles.

If the group has no ticked articles, only the ticked articles will be
shown?

I think there is a misunderstanding here.  What did you mean?

Sorry, that was a little bit confusing. What I really meant was:

If the group contains no ticked articles, then all not-expired
articles are shown. Means: old-and-not-expired articles and new
ones. (I suppose there are no new-and-expired articles ;-)

If the group contains ticked articles, only these and the new ones are
shown.

This is bad, I guess.  Or is this intentional?  Anyone?

Supplement: if the group contains no ticked articles, then

- if the group contains new articles, only the new ones are shown.

- if the group contains no new articles, all of them are shown.

Expired articles are not shown in any of the 2 cases.

This is an imap group, if it matters.

This seems to be just like the default behavior, except that the
default behavior also shows expired messages in the second case.

And what do you want?

Maybe you need to list all of the article types you want, rather than
using negation.

Well, the rule says: "Show me all un-expired articles." Full stop. I
would understand that as "Show me _all_ un-expired articles, in _any_
case, do not distinguish between groups containing new or unticked
articles." Or am I wrong?

Well, I suppose the "error" is, that Gnus shows a different set of
articles if a group contains marked or ticked articles or if it does
not.

Sorry, I hope I have made it clear now. Thanks for your patience.

You're right, you're right.  I was trying to explain what happens,
not what should happen.

According to the documentation, what happens is not what should
happen.

I guess the code should be changed to match the documentation.

The `display' thing mostly says which subset of the articles that
you've already decided to select should be displayed.

`not expired' just says that the expirable articles should be left out
of the initial display limit.

So the documentation is perhaps a bit unclear here...
