group parameter and group-local variables

group parameter and group-local variables

[Seb]

Hi,

I wanted to set `bbdb-always-add-addresses' to have a local value of nil
in some groups, which according to the manual (Section 2.10) can be done
by:

(add-to-list 'gnus-newsgroup-variables 'bbdb-always-add-addresses)

and then 'G c' in the group where I want it turned off and adding this
in the Variables section:

Variables:
            Set variables local to the group you are entering. More
INS DEL Variable: bbdb-always-add-addresses
            Value: nil
INS

However, now `bbdb-always-add-addresses' remains nil globally.  What
could be going on?


Cheers,

Looking at the code, it's copying over all the summary-local values of
the variables in `gnus-newsgroup-variables' to the global variables.  So
it's kinda more a strange hook to set global values for these things.
So you should probably have a top-level topic parameter or the like that
sets this value to what you prefer to have it globally in addition to
the different value you have in that specific group.

The problem is that BBDB gets `bbdb-always-add-addresses' from the
*Article* buffer.  Setting this variable in a topic parameter as you
suggest didn't set its value in the *Article* buffer of the child group.

Sounds like you need to handle this in gnus-article-mode-hook, then.
You should be able to switch on the newsgroup via the
gnus-newsgroup-name variable.
