I think Gnus just has people hit RET after each item.  Entering an
empty item terminates the sequence.  (Gnus has the same problem for
the Newsgroups header.)

Does this help?

Sort of, thanks.

I really would prefer comma separation within a single prompt.  It's a
lighter to use interface.

Emacs has the `crm' library that provides completing-read-multiple.
Should be exactly what you're looking for.

Hmm, i do not know if i understand your problem in the right way...Do you want
this completion in the minibuffer or is it more like dabbrev-completion in a
"normal" buffer?
Even more: What should be the domain of the completion, i.e. the set of
allowed completions??

If you are searching for something in the minibuffer, here is a function:

minibuffer completion, with a comma to separate items to completion.

Exactly like completing-read, an alist of allowed completions.

The documentation for completing-read mentions that TABLE can also be
a function `that does the completion itself'.  Alas, I couldn't find
any more info.

But maybe you could write a dummy function that invokes debug, then
you can see which arguments are passed to the function.

There's more info in the docstring of all-completions, try-completion,
and test-completion (you might not have this last one yet).
And there might also be more info in the elisp manual, of course.

A package might be loaded implicitly by something like `customize'
just to get the list of groups/variables it offers.  You wouldn't
want to turn a feature ON just because you're browsing some of the
related variables (you might even be browsing something that you didn't
know was related).

It should be only

   (bar-cursor-mode 1)

because bar-cursor-mode should be autoloaded.

It's true that it's rarely done, but I think it should be fixed.
My install.el package embryo tries to do that by providing a standard way
for people to install a "package" and that procedure adds the
necessary autoloads.

Why should there be a difference ?  After all, any unbundled package is
just a potential bundled package.

PS: Another circumstance where a package might get loaded implicitly
    is during byte-compilation.  There's probably others.

I'm not familiar with bar-cursor.el, but in general a library can
implement more than one feature.  In such a case, it is usually not
obvious which feature to turn on.  It is best to turn nothing on
automatically and let the user choose which of the features to use by
explicitly turning them on.  Even if a library contains only one
feature now, features might be added in future versions.  Such changes
won't surprise the user if nothing is turned on upon loading the
library.

Furthermore, some other library could (require 'bar-cursor) to use
some function that is defined in bar-cursor.el.  In such a case, you
usually do not want bar-cursor-mode to be turned on.

Hi all,
I often see people posting to newsgroups messages that include some

Try surrounding words with * characters to get *bold*, _ to get
_underlined_ and / to get /italic/ text.

Fine, this works for Knode but that does /not/ work for kmail which is the
mail client I use. Does this work only for newsreaders? Do you know of any
easy-to-use mail client which supports these nice features? Thanks again.

I thought you were talking about newsreaders. My mistake.

I don't believe (I could be wrong) that there's a way to do this with KMail. 
Why? Because it would take HTML. For security reasons a lot of people don't 
want HTML in their mail. Unless the newer version that comes with KDE 3.1 
(I use 3.0) has changed, KMail has a toggle allowing you to READ HTML mail 
if you want, but there's no way to SEND it. Unless you do it as an attached 
file. Attaching a file, though would give you other options, such as 
sending it as a PDF.

The reason for not wanting HTML in your mail is that someone could send you 
an e-mail with code in it that could set off an attached virus without you 
even executing the file. I don't know how prevalent these are, though. Plus 
the overwhelming majority of viruses are written for Windows, not Linux.

And there are people that lament the additional usage of bandwidth just to 
make the message colorful. I don't find this argument compelling but I do 
have security concerns.

I also don't know if there are other Linux e-mail programs that allow you to 
send HTML mail. Some of the others I looked at didn't appear to. But things 
change and my distribution is a year old.

It becomes compelling as soon as your only access to the internet is a
connection that is supposed to be 56k but most of the time crawls with
about 30k, and you receive about 50 to 70 mails per day, and the
majority of that mail contains html or html+text, with full quotes,
that are between 3 to 10 times larger than necessary.

I don't find the securety argument compelling. Whatever bad script
there may be contained in the HTML, it has to be interpreted to do any
harm and my mailreader is well educated and doesn't do bad things[1].

Another thing for which I detest 99% of all the HTML mails is the idea
that it is a good thing to force a specific font at a specific size in
a specific color with a specific background on me. *I* know best what
is good for my eyes. Noone else does.

That is not to say that I wouldn't welcome some syntactic markup
language that would provide something like <h1>, <h2>, <b>, <ul> ...
etc. But not much more. Something like an extended text/enriched, but
text/enriched itself is a bit too poor ...

You asked how you could write the bold, underlined and italic text in
Emacs.  The writing part can, of course, be done by any editor.
Displaying words marked as such must be supported by the mail or news
reader.  I was under the impression that most did support this system,
but I don't know that many mail/news readers.  I use Gnus, which is a
combined mail and news reader written in Emacs Lisp.  It gives me one
reason less to leave Emacs.  Gnus supports this underlining and such.
It's also quite easy to use.  Once you have set it up right, that is.

Surrounding words with * is new to me, it sounds useful. I personally
mark the words and then use M\bM-\b-g\bg b\bb for bold, _\bM_\b-_\bg
_\bi for italics, _\bM_\b-_\bg _\bu for underlined.

Any standard function to prompt for multiple comma-separated items?

[Peter S Galbraith]

Hello,

For MH-E, I'm looking for code already available in Emacs to do
completing-read for multiple comma-separated items.  e.g.

To: p.gal[TAB]
->
To: p.galbraith
->
To: p.galbraith, psg[TAB]
->
To: p.galbraith, psg@home

Does anyone now of such code already existing?

There's multi-prompt.el bundled with AUC-TeX that comes close (doesn't
allow whitespace after the field separator), but I need something I can
use in MH-E without external packages.

Thanks,

the real file-attributes function

[Kin Cho]

Hi,

I want to use the real file-attributes, not the ange-ftp
overloaded one.  In other words, how do I stop this:

(file-attributes "/ftp.geocities.com:/")

from opening a ftp connection?

I see this line in
(put 'file-attributes 'ange-ftp 'ange-ftp-file-attributes)
in ange-ftp.el

so I tried:
(put 'file-attributes 'ange-ftp 'file-attributes)

but this causes infinite recursion when I eval 

(file-attributes "/ftp.geocities.com:/")

Thanks.

(remprop 'file-attributes 'ange-ftp)

Fiddling with those attributes will just break ange-ftp.
You're better off disabling it rather than breaking it.
Take a look at file-name-handlers-alist and remove the ange-ftp
entries there.

I'm curious, tho: why exactly do you want to do that ?

So that's how you disable ange-ftp!  It ought to have a defcustom for
that...

I _never_ use it, and I'm always annoyed the first time I try to open
a file, press tab after / in the prompt, and emacs loads ange-ftp.

Or alternatively,

It is _exactly_ what I wanted.  Thanks!

But this is only true if its defcustoms are copied to another file,
right?  How else could it get loaded?  Or do you mean if the user loads
it in order to see its customizations?

But this is only true if autoloads are generated.  Is it standard
practice to do that for files added to someones site directory or for a
user under $HOME?  I know I've never done that (I might start now that I
think of it).

I'm not talking about a file are is part of Emacs, but one distributed
separately.  How strongly should we adhere to that coding convention?

Thanks!

Activating Mousewheel

[Florian Lindner]

Hello,
how can I enable the mouse wheel for scrolling (MS Intellimouse Explorer on 
USB)?
From my X config:

Section "InputDevice"
    Identifier "Mouse1"
    Driver "mouse"
    Option "Protocol" "ExplorerPS/2"
    Option "Device" "/dev/usbmouse"
    Option "ZAxisMapping" "4 5"
EndSection

It works with KDE.

I've tried
(require 'mwheel) but not effect. Emacs is 21.2, most recent release.
Thx,
Florian

With a

?
