emacs-21 and gnus

emacs-21 and gnus

[reader]

Noticing the windows copy cat stuff on recent emacs-21, I'd like to
turn of some off the more blatant ones.  One inparticular seems to
effect gnus usage in a bad way but only on a Solaris 8 (intel)
install. 

Probably because of no XFree86 stuff.

I'm sort of bending the stick here by using the gnus related thing
to get some advice on emacs-21 customizations.

Using M-x customize-apropos with several search strings like 
`button' or `menu.*bar'.  Hasn't turned up the needed adjustments.

Who know what they might be called?

1) Remove the little tool icons across the top and the chunk of
   real estate that contains them. It uses needed space.
2) stop the little redundant dialog boxes that pop up over all the
   menu items, obscuring sections of the screen. 

Number 1 has a very bad effect when in gnus group buffer.  For some
reason those icons are broken and look like h___.  Where as, the other
gnus buffers and emacs buffers look sort of ok but still worse than a
linux install where XFree86 is installed..

Above only applys to the Solaris install.
The icons look ok on linux but I still want them off, preferring to
use that space for viewing files.

Cool .. I gained two full spaces of realestate.

Now about those 2 black sripes that run veritically just inside the
border.  One on either side,  and a few pixels wide..... hmmm

M-x set-variable RET truncate-lines RET t RET

Then open a file with long lines.  Then set the variable to nil.  See?

(M-x gdb RET also uses the left hand strip for its `this is the
current line' arrow.)

WIBNI Gnus used this for showing the current article in the summary
buffer? Might be a more generic way than the recent discussions about
highline.el etc.

How about the following?  I couldn't find a way to do this in XEmacs;
maybe an XEmacs guru will have a way to make it work there too.

Well, I didn't realize that Emacs 20 and XEmacs both appear to have
`overlay-arrow-string' and `overlay-arrow-position', too.

But at least in Emacs 20, the arrow will obscure the first two
characters of the current summary line.  Maybe this isn't a problem?
Or maybe the thing to do would be to make it a user variable, and
default it to true.  The people who dislike it could then set it to
nil.  Thoughts?

Some users still might want that, true. If not, it adds some incentive
to switch to Emacs 21 ;-) 

What do they get on the console?

Sounds reasonable to me. Or maybe set it to nil per default, and after
people start using and liking it, make t the default.

Unfortunately, I cannot really try your first patch since I still
didn't switch the either XEmacs 21.4 or Emacs 21 (which is more
likely to happen).

  Colin

It does look nice in Emacs 21.  Screen shot at:

An arrow overlay, just like in Emacs20 and XEmacs.

Another option is to make it turned on by default only if:

(and (string-match "GNU" (emacs-version))
     (>= emacs-major-version 21)
     (display-graphic-p))

Well, it does work in Emacs 20, too.  It *should* work in XEmacs, but
I haven't tried it, because my init files and everything are too
tightly bound to GNU Emacs.

Indeed.

I applied your patch, and it works. The arrow overlay is easy to miss
though, so it doesn't add much. Maybe if it was a distinct color...

Ok, yes.  I see what they do.  I guess I'm having a little trouble
seeing how those little arrows are better than the standard \.  Which
is known the world over as a wrapped line symbol and it took almost no
space.   Is there some clear advantage to redundant arrows?

Well, the arrows look nicer.  Also, note that Emacs couldn't use the
last column for text anyway, since the last column was occupied either
by "\" or by "$" (or by " " for short lines).  So it's not that you
are losing screen real estate (for the right hand strip).

I don't mind the superfluous left hand strip.  After all, it comes in
handy for gdb...

Yeah, I guess it isn't such a big deal.  One thing is clear though:
Emacs developers should be sent on a nice sea cruise to the Carribean
or something for the nifty work on syntax colors in console/character mode.
Anyone taking up a collection?  : )

Syntax highlighting via telnet, ssh or other remote usage... Ultra
cool.  Now my favorite editor is really much more usefull.  I can set
in a recent Java class and ssh home to use my own emacs running on a
solaris (intel) (The home port of java.. sort of) for editing while
the others are struggling with wordpad or something.  And, I'm seeing
the code in nifty colors that help me keep the mistakes down.

For any other solaris (intel) users:  I've found I can ssh in from
just about any TERM setting supporting ansi colors.  Then set the
Remote shell to TERM=sun-color and the syntax highlighting comes thru
like a champ.

It seems to conflict with other customizations.  Until now I didn't find

emacs-21 and gnus

[luis fernandes]

Under Solaris (I had the same problem), you have to make sure you
have a certain xpm library version (or better) or emacs21 will be
configured to use pbm (mono icons).

The 21.0.103 pbm icons suffered somewhat during the conversion from
the xpms (or whatever); I recently sent Gerd touched-up versions of
the tool-bar icons which should appear in the next release.
