gnus-group-customize seems to fail

gnus-group-customize seems to fail

[Uwe Brauer]

Hi

my normal setting for replying mail is as follows:
 '(sc-citation-leader "    ") '(sc-reference-tag-string ">>> ") 
 '(message-yank-cited-prefix "   > ") '(message-yank-prefix "   > 
 ") 

now in a specific group I want to delete the empty space before 
">"

So I run  gnus-group-customize
and set

 
Variables: 
            Set variables local to the group you are entering. 
            More 
INS DEL Variable: sc-citation-leader 
            Value: "" 
INS DEL Variable: message-yank-prefix 
            Value: ">" 
INS DEL Variable: message-yank-cited-prefix 
            Value: ">" 
INS 

But now effect! The original setting was not overwritten.

What do I miss?

Regards

Uwe Brauer

I believe you ran into https://debbugs.gnu.org/26105 ("Group
parameters can't set non-list values").  I don't see an easy
way to work around that for your use case.

I  found out that just the variable sc-citation-leader I have to change.


Now in the summary buffer describe-variable returns



,----
| is a variable defined in ‘supercite.el’.
| Its value is ""
| Original value was "    "
| Local in buffer *Summary nntp+news.gmane.org:gmane.comp.tex.german*; global value is "   "
`----

So far so good, but when I press reply or followup, the global setting
is used, which is not what I want. Is this really the same bug you
describe? It seems that in your case there is a workaround. Is there
also one in mine?

Thanks

Maybe I misunderstand something here but sc-citation-leader is local to
the summary buffer so its value will not propagate to a message buffer?
I.e. not a bug.

Well but how can I then pass that variable to the message buffer, but
only groupwise?

I suppose with posting styles?

I tried

        ("gmane.emacs.gnus.general"
         (header "Newsgroups" "gmane.emacs.gnus.general")
         (setq  sc-citation-leader ""))

But it does not help

Oops, sorry! I thought you could set arbitrary variables as part of
posting styles, but it look like I was hallucinating. Sorry about the
misdirection...

Maybe look at the message package, not gnus, as message is responsible
for composing emails?  For instance, you could put some code in
message-header-setup-hook which sets the variables you want depending on
the contents of the message header?

I found a workaround with bbdb, so for a particular recipient I set that
variable to nil. So far so good.

But then in the sending hook I need a function which resets the variable
to my standard setting. This is for sure a kludge but I don't know how
to do better.

Try (eval (set (make-local-variable 'sc-citation-leader) "")).

Aha, that works! Thanks, I will never understand that difference in the
settings. So I can undo my .bbdb solution, which was cumbersome anyhow.
