Yes, those are `gnus-emphasis-bold', `gnus-emphasis-italic'
and `gnus-emphasis-underline'.

If one feels the need to use them it can be a sign that the

But as long as there is a summary buffer one could use point
to determine what article to act upon, so, if someone would
solve that practically, then a similar, improved version of
that function would be callable from wherever in Emacs and
still find and article and, from there, a header field value.

We would like an arbitrary header access function where the
header is provided as an argument, as in

(defun gnus-article-header-value (hdr)
  "Get the value of HDR for the current article."
  (with-current-buffer gnus-original-article-buffer
(gnus-fetch-field hdr) ))

 only one that works from anywhere, where the article is
fetched from what article is selected (or, lacking that, where
the point is) in the summary buffer.

Probably, but how that works I don't know, this

(gnus-summary-article-number)

is 20086 in the summary buffer but opening that up and doing
the same thing in that buffer (the article buffer) I get
20085, but not point nor highlight has moved in the
summary buffer ... ?

Yes, I tried the function `mail-header' ...

The function `mail-header-subject' works but then you don't

Get data like this:

It will  then be the summary buffer article at point, not the
selected one. If one is selected, it would make more sense to
operate on that.

If there isn't an article open, you can do that - with code -
from the summary buffer before you fetch the field. If there
is no article buffer and no summary buffer it is hard to think
of a use case and moreover it will be hard to determine, in
a way that makes sense, what mail or post the user refers to
when hitting the command.

You mean like this?

You can use `message-fetch-field' to get headers, as in:

(defun message-yank-subject ()
  (interactive)
  (save-excursion
(let ((subj (message-fetch-field "Subject")))
  (when subj
(message-goto-body)
(insert (format "%s\n" subj))

It can be auto-added or cached somewhere else. (Unintended
pun: 'cache' is from the French word not to store but
to HIDE something.)

Well, that whole situation of adding/removing servers several
ways, and how the methods don't auto-sync, that was discussed
a while back.

Get around the situation by not adding them interactively,
always use .gnus, which is better anyway so no harm to it.

But to try to help you, what I'd do is delete everything
everyway you can and everywhere; kill Emacs; re-bytecompile
everything; start Emacs and see if anything is left; if not,
add it again, but only the stuff you want, and only one time,
in .gnus.

[Side note: Gnus, and Emacs in general, don't care where you
put configuration/extension as long as you tell Emacs where it
is and that it should be evaluated. Because: .gnus is, as
everything else, just a file with data. I, for one, don't even
have a .gnus, instead, I have all Gnus here:

  https://dataswamp.org/~incal/emacs-init/gnus/

and I load every file there explicitely from .emacs]

Indeed, it shouldn't work with lexical/static scope since,
despite `setq', b is not a global variable. So it'll be
undefined in 'c'.

Yes, with dynamic/special scope it does work but it's not
encouraged to use that unless one has a good reason. Actually,
to use that _in general_ I think is never encouraged. One can
still have individual variables that are global tho if and
when that's called for ...

That's normal and in particular in this case ...

I'm saying

1) Always use lexical/static scope, i.e. put 

;;; -*- lexical-binding: t -*-

first in all and every new Elisp file you create.

2) In this case, since there is a formal parameter with the
same name, `setq' does not create a global variable.

  (defun strip-signature (re  rep)
(or rep (setq rep ""))
;; ...

This is OK. Only if you misspell "rep" to something that isn't
rep (or re) a global variable will be created :)

'rep' is a formal parameter of the function, under
lexical/static scope - which you should always use BTW, put

;;; -*- lexical-binding: t -*-

topmost in your file (every Elisp file) if you didn't - that
means you get a local variable that again is lexical/static
and, equivalently, not dynamic/special.

Just try - and you will fly ...

;;; -*- lexical-binding: t -*-

(defun c ()
  (message b) )

(defun a (b)
  (message b)
  (setq b "ah")
  (c) )

;; (a "oh")
;; ^ eval me

Also, byte-compiling this will echo a warning saying b is
a free variable, and this even under dynamic/special scope
where the code actually works tho (i.e. this particular use of
'a' and 'c' where 'a' is used first).

This can be made look better (reduce programmer's reading and
typing code) by making the second formal parameter to
strip-signature , it'd then default to nil which your
function could treat as "don't replace, just drop". That way
you don't have to give those ugly "" as arguments all the
time. But it's absolutely not wrong the way you have it.

In general, if the last argument can be nil for no, empty, nothing,
or does not apply, this argument can safely be made optional
from the above perspective.

Be sure to try it for type (or set it to, e.g. 0, if nil
implies that) before using it as an integer or string tho, as

  (integerp nil) ; nil
  (stringp nil)  ; nil

See this file:

  https://dataswamp.org/~incal/emacs-init/dwim.el

In your case, you could do

(defun strip-signature (re  rep)
  (or rep (setq rep ""))
  ;; ...

and not have to change anything else.

I'm sure you can develop it along the same and other lines but
you have understood the message, good. REs are very useful and
you got a lot of practice on those. But also a piece of code
that did what you wanted.

Make the whole thing a function that you add to the the hook.

Use blank lines to separate different parts.

This also makes it easier to test, you can simply call
the function.

And try out and optimize the different parts one by one.

But only do modules when it makes sense semantically, i.e.
when one can clearly say "this function does this, this other
function does something different", don't split it up just
because "this function is too long".

One way to check if it does make sense is to write names that
makes sense, when that is difficult, "hm ... what DO we call
THIS function?" then that is an indication that function isn't
a good idea.

So while in general it's good with modules but in particular
good modules are even better ;)

Here it may be a better idea to have those REs in a list and
then iterate that (a loop) instead of calling the same
function so many times.

For modular, idiomatic Elisp the TODO list would be:

1. Split into functions with names that explain what they do.

2. Instead of `replace-regexp', use

   (while (re-search-forward RE nil t)
 (replace-match STR) )

See the docstrings for those three functions.

If you quote a lambda it is just a list with data:

'(lambda not an anonymous function)

Eval and you will see, there's no difference in

It is a bit confusing to call them that. It is a local

That's probably not the way to do it, I think that, i.e.
`gnus-signature-separator', should be used only for the
separator(s) per se and not in order to do other stuff like
that, since processing is likely to be based on that and what
you don't want to see last maybe appears in the middle of the
mail and other such unpredicted (?) situations ...

That kind of stuff you want can be done tho for sure, did you
check out this chapter:

  (info "(gnus) Article Washing")

Have a look at `article-translate-strings',
`gnus-article-strip-multiple-blank-lines', and
`gnus-article-prepare-hook' ...

You can hide the quoted part (instead show a button which will

In the Group buffer, hit the key for

Fake news is when you post news in a style and layout and
everything so it looks and reads like news, but the actual
news article is fabricated with a political agenda and facts
may not be true, it can be to make a specific person look bad
but it can also be with the purpose to make media look bad, to
have people confused so they loose faith in media and
politicians and the whole society, in general.

That's something else, to see how the colors
look when actually displayed.

It sounds like you have it misconfigured
somehow.

You don't need anything on these URLs, they are
just examples how it can look and what you
can do.

Just require everything, then set the faces,
byte compile, correct warnings and
errors, do it again, done. Easy.

You can use this to find out what face
something is:

(defun what-face (pos)
  (interactive "d")
  (let((face (or (get-char-property pos 'face)
 (get-char-property pos 'read-cf-name) )))
(message " Face: %s" (or face "(no face!)")) ))
(defalias 'wf #'what-face)

Then do, for example:

(modify-face 'gnus-group-mail-1 "cyan" nil nil t)

Now I've found it! But this paleo-computer

a smartphone here that can! So I'll just type
my own code... but first:

$ # from

what that just six years ago? it feels like 15
or 20!!? :O

more modern and macho (goto-char (point-min))


(defun gnus-summary-respool-all ()

  (let ((lines (count-lines (point-min) (point-max
(goto-char (point-min))

That's right, manually create the NOT

Just check it out and it doesn't add up, it

So it was called something unusual, is all

What you look for is called respooling.

I've done it several times, one was from Rmail
to nnml, _I think_! ... then a couple of other
times in more creative/exotic ways, but it was
so long ago, and in all my Elisp there is not
a single trace of it... :(

You want respooling from nnmaildir to nnml,
i.e. from one mail spool to another!

I'm pretty sure it exists, but if it doesn't,
congrats, you have found a great spool I mean
spot to start writing a wonderful new algorithm
to Gnus, maybe the longest program ever
written :)

OK, final word: respool

The first thing I always ask when it comes to
mail splitting is what is the reason? Is it to
organize mails from different mailing lists?
Then, the answer is it is much better to
use Gmane which does all that for you, and more.

> here is my config, but it doesnt work.

Not me, be start small is a good ... start.
Try just splitting one type of mail to
one group.

You can change the rules, then go to a mail in
a Summary buffer and press `B q'. Gnus will
then tell its destination, would it arrive
today or if you respooled it. If it tells you
a destination that isn't to your liking, that
means the rules are incorrect or not applied.

This is all I have, and it works great. Yes,
I said Gmane is better, and I have all that
(save for the rsmh-ooa) as Gmane groups.
But sometimes (rarely) stuff find their way to
my mail.misc anyway, that's why I have
a "mailing list out-of-action" group
(mail.mm-ooa) to get them away so I don't see
them twice.


(setq nnmail-split-methods
  '(
("mail.ml-ooa"
"\\(To\\|Cc\\):.*\\(help-gnu-em...@gnu.org\\|d...@gnus.org\\|emacs-...@namazu.org\\|emacs-de...@gnu.org\\|gmane-disc...@quimby.gnus.org\\|tex-l...@tug.org\\|gnuplot-i...@lists.sourceforge.net\\)")
("mail.ml-ooa""List-Id: ")
("mail.ml-ooa""List-Id: Users list for the GNU Emacs text editor 
")
("mail.rsmh-ooa"  "From:.*\\(Tikan \\|RSMH\ 
Uppsala\\|i...@verkstanrsmh.com\\)")
("mail.misc"  "")
  ))


If you use another backend, maybe it won't work
without some changes, but it could be a start
for examining how it would work using your
backend as well.

Good luck and HIH

Not with Gmane as far as I know, I consider
that part of Gmane. You can use NNTP thru
a Usenet server, of course, e.g. nntp.aioe.org,
and then post to the equivalent newsgroup if
available, e.g. gnu.emacs.help instead of
gmane.emacs.help. Probably the poor man's

If you for some reason don't want to use the

I don't have that as a function but it means it
expects an argument that is accepted by the
`number-or-marker-p' test, and now what it gets
is nil which doesn't pass.

This most often doesn't happen because some
complete lamer is sending it nil and expect it
to work, but rather some symbol is passed that
most often makes sense, only right now it isn't
set, or set incorrectly/unexpectedly to nil.

Sounds like you have a group but no

/home/incal/Mail/drafts
/home/incal/News/drafts
/home/incal/News/drafts/drafts

do you have it/them as well?

Better to do this in the shell's environment
file, e.g. ~/.zshenv for zsh:

export TZ='Europe/Stockholm'

You can pass this to a tool without setting it

I've had this/a similar issue for several

as well, for sure :) What happens is, when I do
`gnus-group-get-new-news' I get news alright,

message, and no mail update.

Mail source (pop :user moasen :password
XYZ123 :server pop.zoho.com :port 995

However, because the error message just flashes
by, I simply read the news and sooner or later
I get the mails, if any. Not the power user
way, perhaps...

What mail client do you use?

If it archives the post/mail as a single text file,
you can use

$ ls -b -l FILE

or

$ wc -c FILE

to count the bytes/chars, including the headers.

As for the attachment you can do the same (ls -bl) on
the file and then add the number of bytes to that of
the text file.

Remember it is not only an alphabetical sort,
it is implicitly a theme sort because of the
hierarchy style of naming groups.

To sort groups based on score - how would you
then find a particular group? No scoring system
will ever be so good as to put the right group
in front of you every time.

Take a look at these dumps:

http://user.it.uu.se/~embe8573/gnus-abc/

One key to get a subset of groups - here, those
with traffic *and* above level 3, inclusive.
Note that this list is also in ABC.

Another key to get every other group.

So in essence, keep sorted, remove subsets.

I post the Elisp here, perhaps you can use it
to do whatever it is you want to do:

I have not seen this error message but what is your
`user-mail-address' after the Elisp - does it
look right?

The simplest way to do this manually is to use the
.mailrc file - one line would look like this:

alias w3m "w3m-el list "

It'll be manual but very quick. One stroke to bring up
a new empty mail, three strokes to write "w3m".

The .mailrc file is great for person-to-person mails
as well, and as an address book.

To do this automatically it can be done with the
gnus-mailing-list-* functions, perhaps with a bit of
tweaking (i.e., look how it is done, write your own
defun) - however this is all based on getting header
data from a present article (or mail). If there isn't
one, it won't work.

I suppose you could set up an association table
between what you call the lists as groups and their
addresses. Too much work for such a small gain,
I'd say.

Oh, yeah? Some of the questions on gmane.emacs.help

One idea that is good tho is providing essential

A lot of text there. Care to quote where this is

You tell me!

You are saying you are not accepting any new lists at
the moment?

Well, NNTP is the *protocol*, so Gmane is also
NNTP, it is a mail-to-news, or NNTP, gateway.
Still, I like to think of Gmane as Usenet 2.0
or Usenet Reloaded :)

As for mailing lists that are on Gmane,
use Gmane.

If they aren't, make sure they are :)

If you cannot -- hey, what lists are you on
anyway?! -- if you cannot, use mail splitting
to steer the traffic into a group which you
name whatever you want.

Note that this isn't as good as Gmane even if
done rightly because all the traffic gets to
you, not just the posts you care for, but it
should work as a way to organize
incoming mail.

Mail splitting can be useful tho, e.g.
create a mail.spam group and then steer spam
into it.

Well, isn't your Group buffer sorted
alphabetically already?

`gnus-summary-post-news'?

What server do you get them from?

Do `gnus-group-enter-server-mode' in the group
buffer to see if it is offline. If it is closed
open it up with `gnus-server-open-server'.

I have these groups from nntp.aioe.org and it
seems to work fine, tho I don't use
gnu.emacs.help but gmane.emacs.help (and so on)
these days.
