problem with gnus-summary-line-format.

problem with gnus-summary-line-format.

[Maciej Matysiak]

hi,

i started to play with summary line format (since we can have nice tree :)).
so far, so good, i've changed the one i've been using for years to something
completely different. now it looks like:

 ( 6: 13) strangely-placed cursor in sum > Bill White
 ( 1: 20) +->                                > Bill White
 ( 2: 19) +->                                > Karl Kleinpaste
 ( 1: 11) | `->                                > Kai Großjohann
 ( 2: 13) `->                                > ShengHuo ZHU
 ( 1: 22)   `->                                > Bill White

but it doesn't look as nice as it could:

 ( 6: 13) strangely-placed cursor in sum > Bill White
 ( 1: 20) +->                            > Bill White
 ( 2: 19) +->                            > Karl Kleinpaste
 ( 1: 11) | `->                          > Kai Großjohann
 ( 2: 13) `->                            > ShengHuo ZHU
 ( 1: 22)   `->                          > Bill White

the format i use now is:

(setq gnus-summary-line-format "%U%R %z \(%2t:%3L\) %B%30s > %f\n")

could please someone advice how to shorten the subject field by thread
level? (at least i think that would what i want).

greetings,
 m.m.

To get this kind of effect, you could put the names on the left.  That
could be a workaround until someone tells you how to do what you are
asking for.

Btw, another idea might be for %B to show the subject rather than `>'
for the root of a thread.  What do you think?  Then it might be
possible to just say %40B in gnus-summary-line-format.

Thoughts?

that doesn't look nice for me.

how? after checking apropos for subject, i've tried:
 (setq gnus-sum-thread-tree-root (gnus-summary-subject-string))
and
 (setq gnus-sum-thread-tree-root (gnus-summary-article-subject))
but both don't do what i want. (btw., what's the difference between
therse functions?)

very good idea, much simpler than the solution i was thinking about.
i just need to assign the post's subject to gnus-sum-thread-tree-root :)

btw., there's small bug somewhere: i change the gnus-summary-line-format
in *scratch* buffer, using ctrl-x ctrl-e for evaluating the changed line.
then, go to *group* buffer, and enter a group. but gnus somehow remembers
old gnus-summary-line-format. the new is used when i enter a group second
time.

Atleast for me, threads do change subjects even when not at root. I
gather threads by references.

I have no idea what the current tree building code will do when that
happens.  Hm.  Lessee...

Aha.  It just draws a tree.

What do you suggest should happen in such a case?

It works perfectly for me atleast. I see the new subject whenever it
changes, but the thread trees are intact. And %B summary format
ofcourse works fine.

What I meant that the thread root just having the summary listed is
not sufficient - and that some people might want summary listed for
every entry and so on.

No, no.  That's not what I'm talking about.  You can set
gnus-sum-thread-tree-root to nil, then it will insert the subject.
This way, you can put %B _without_ %s into the summary line format,
and you will see a tree with subject.

But when the subject changes, that feature won't do the right thing.
To get the right effect there, one needs to look if the subject has
changed, and optionally append the subject to every node if this has
happened.

yupp, that's what i do.

oh. for me, it's a feature :) at least, now i see just the thread, without
the-bat-borked subjects (re[7]: blah) and subjects with polish characters
malformed by readers who can't quote properly.

if you/someone fix it, please make it an option :)

I see.  Hm.  Okay, I'm happy then.  But I think the feature should
still be changed so that there is a user option to insert the subject
even inside a thread when the subject has changed.

Ah yes, you already talking about the %B tree building code. I thought
you meant the normal tree building, which was silly of me.

In my opinion, the decision between showing the subject or not showing
the subject is not limited to just changing subjects and root. I, for
example, am a bit annoyed by the fact that when I'm reading news
articles, if the thread is long, I don't see the current subject from
it - I have to look at modeline or article headers, and both are far
away. So I might want "%S" and not "%s", so to speak. Or maybe
something even more complex, like showing the subject every 5 headers.

It seems that "%B%s" or "%B%s" is almost what's needed, except that
the width limitation can only apply to one specifier at a time, and
it's difficult to specify a max width for the combination of the two.

Or is it possible?  Then I would remove my klugy feature.

I have now done this.  It's a kluge, however.  But you can just set
gnus-sum-thread-tree-root to nil, and then the subject will be used.

I've also added a little bit of documentation.  Please check if it was
right.  (The variables gnus-sum-thread-tree-*.)

I feel that it should also be mentioned in the documentation that
certain strings should have the same width.  For example, the tree
will look strange if the indentation and the vertical line string
don't have the same width, I imagine.  Could someone list all the
constraints?

yay! thanx a lot! :)
i use now:
 (setq gnus-summary-line-format "%U%R %z \(%2t:%3L\) %-40,40B > %f\n")

one thing i can't find how to customize... now i have:

i'd like to make it:

  :           : Re: bah, i've had it with html

where should i look? where/how is that line configurable (if at all)?
i can't find it in documentation.

yes.

> (The variables gnus-sum-thread-tree-*.)

i've customized them already, especially i like:
 (setq gnus-sum-thread-tree-single-leaf "`-> ")
more than "\\-> ".

Maybe the look of the first line comes from gnus-summary-dummy-line-format?

of course, you're right :) (and apropos for gnus.*line-format showed me
a lot of other things i'll play with now :))

anyways, there's small bug. i described it already yesterday: after changing
gnus-summary-.*line-format, the modifications are visible after i enter
the group second time. for the first time, gnus somehow keeps old settings.

Sounds like a caching problem.  I've now tweaked the caching mechanism
a bit...

It turns out that I forgot about gnus-sum-thread-tree-single-indent.
I've now changed it and now you can set that to nil, too.
