Make gnus-summary-line-format %B prettier?

[Kai Großjohann]

I think on Emacs 21 it should be possible to use line drawing
characters for the %B specifier.  How does one do that?

That's a neat idea.  Here's what I came up with:

(setq gnus-summary-line-format "%U%R%z%(%[%-23,23f%]%) %B\n")
(setq gnus-sum-thread-tree-leaf-with-other "├─▶ ")
(setq gnus-sum-thread-tree-vertical "│")
(setq gnus-sum-thread-tree-single-leaf "╰─▶ ")
(setq gnus-sum-thread-tree-root nil)
(setq gnus-sum-thread-tree-single-indent nil)

Threads look like this:

BTW, how should I save my .gnus to make it work?  When I evaluate it
with `C-x C-e' it works, but loading from .gnus doesn't.

Not bad.  I use it now, except that I removed the arrow-heads.

There is still a problem: some arrow-heads have a vertical line below
it, but some don't.  Is it possible to tweak the variables (or the
code) such that different characters can be used for them?

I enabled it by putting the lines in ~/.gnus, saying C-x RET f utf-8
RET, putting "-*- coding: utf-8; -*-" in the first line of the file,
then saving it.  Does that work for you, too, Jesper?

Yeah, it looks better with no arrowheads.  I think this version is
nicer:

(setq gnus-sum-thread-tree-leaf-with-other "├╮ ")
(setq gnus-sum-thread-tree-vertical "│")
(setq gnus-sum-thread-tree-single-leaf "╰─╮ ")
(setq gnus-sum-thread-tree-root nil)
(setq gnus-sum-thread-tree-single-indent nil)

I think it would look slightly better, if you could use a different
string when an article doesn't have children -- maybe like this:

   [Kai Großjohann         ] ├╮

But then you'd have to change the code.

No it still doesn't work.  When .gnus is loaded automatically I get this
value:

   gnus-sum-thread-tree-vertical's value is "\342\224\202"

But when I open it with `C-x C-f' and do `M-x eval-buffer' I get the
right value:

   gnus-sum-thread-tree-vertical's value is "│"

Hmm, when I loook at `gnus-read-init-file', the file is loaded like
this:

     (let ((coding-system-for-read
	    gnus-startup-file-coding-system))
       (load file nil t))

and `gnus-startup-file-coding-system' is bound to 'binary by default.
Doesn't that override the comment line?  When I bind
`gnus-startup-file-coding-system' to 'utf-8, it works.

What font/terminal program are you using?  I can't seem to make those high
characters come out as anything but gibberish (using fixed fonts in an
xterm, gnome-terminal, using an X emacs window, and using the linux
console).

I'm using an X11 Emacs window with one of these fonts:

-Misc-Fixed-Medium-R-Normal--13-120-75-75-C-70-ISO10646-1
-gnu-unifont-medium-r-normal--16-160-75-75-c-80-iso10646-1

What happens if you do:

     `M-x list-charset-chars RET mule-unicode-2500-33ff'

(that's where I found the line drawing chars).

Thanks for the quick reply.  list-charset-chars shows the arrow chars
correctly, which pointed out to me that I cut/pasted your original post
incorrectly...  Oops.  So, fixing that, I get your tree display nicely on an
X emacs window.  Thanks.

Of course, now that it works, I want it to be different...;)  
I (think I) want it to look like:

mark score [Author]  Subject
             |---> Author 2
                 |-->Author 3
             |---> Author 4

A quick look at the manual doesn't seem to show how to do this, though.  The
%B mark constructs the arrows together with the subject field, so if I
just do "...%B%f I get the followup lines the way I want them, but the first
line will be "Subject Author" instead of "Author Subject".  Is there a way
to control the construction of the %B variable, or to just get the "tree
components" of the variable (without the subject on the first article of a
thread?)

Thanks,

I think this does aproximately what you want:

(setq gnus-summary-line-format "%U%R%z %B%-23,23f %s\n")
(setq gnus-sum-thread-tree-leaf-with-other "├╮ ")
(setq gnus-sum-thread-tree-vertical "│")
(setq gnus-sum-thread-tree-single-leaf "╰─╮ ")
(setq gnus-sum-thread-tree-root "")
(setq gnus-sum-thread-tree-single-indent "")
(setq gnus-summary-same-subject "")

Where did you get the gnu-unifont font?  This is new to me.  Oh - is
it part of intlfonts or whatever that's called?

Empty boxes here.  I use this in my ~/.Xdefaults:

Emacs*font: -b&h-lucidatypewriter-medium-r-normal-sans-12-120-75-75-m-70-iso8859-1

It's Roman Czyborra's unicode font <http://czyborra.com/>.  I got it
from an RPM bundled with my Linux distribution.  The other one is
included in XFree86 (4.0.3).

What happens if you select fontset "default" or "standard: 16-dot
medium" from the font selection menu?

Thanks!  I'll check it out.

In both cases, those characters still show up as empty boxes.  With
the special character in this line
(setq gnus-sum-thread-tree-vertical "│"),
"Options - Mule - Set Font/Fontset - fontset - default" gives me this:

----------------------------------------------------------------------
  character: │ (01110042, 299042, 0x49022)
    charset: mule-unicode-2500-33ff (Unicode characters of the range U+2500..U+33FF.)
 code point: 32 34
     syntax: w 	which means: word
   category:
buffer code: 0x9C 0xF2 0xA0 0xA2
  file code: 0x9C 0xF2 0xA0 0xA2 (encoded by coding system emacs-mule)
       font: -LFP-Uniread-Medium-R-Normal--9-90-75-75--60-ISO10646-1
----------------------------------------------------------------------

"Options - Mule - Set Font/Fontset - fontset - standard 16-dot medium"
gives me this:

----------------------------------------------------------------------
  character: │ (01110042, 299042, 0x49022)
    charset: mule-unicode-2500-33ff (Unicode characters of the range U+2500..U+33FF.)

       font: -gnu-fixed-medium-r-normal-f-16-160-75-75-c-80-iso10646-1
----------------------------------------------------------------------

Turns out I once fooled around with some branch of Czyborra's unicode
font. I'll try the real thing.

FWIW, I see all those pretty chars with Emacs.font: 6x13 in
.Xresources.  This is with XFree 4.1.

Hm.  Normally, Emacs 21.1 running under X11 should show the right
characters, but maybe you need Unicode fonts?

In the console, it is expected not to work.  Unless you are using a
Unicode terminal program, that is.

Probably a side effect of setting coding system of ~/.gnus to utf-8.

Well I don't neither anyway. I use :

emacs21.font: -monotype-courier new-medium-r-normal-*-*-100-*-*-m-*-iso8859-15

Doesn't see anything in the previous message... :(
