Getting started with the agent

Getting started with the agent

[Niklas Morberg]

I'm using gnus 5.10.6 and am trying to get the agent up and
running for IMAP. Here's what I do:

(setq gnus-agent t)

and restart gnus. I want to download all articles for my
groups. From the documentation I read that I need to create
a new category and then add all groups to this category
(this seems a bit to complicated, but I play along). This is
what I do:

- `J c' in the group buffer
- `a' to add a new category called "everything"
- `e' to edit the category
- Change the "Selection Predicate" from `false' to `true'
- Press "Done"

The result is this:

gnus-category-prepare: Wrong type argument: sequencep, ignore

and nothing seems to work properly after this. Am I going
about this the wrong way? Is there a better way to tell the
agent to download all my messages?

Shouldn't be required, I think.

Isn't there already a `default' category?  I recall one being created
automatically.

I get the same error, and I reported it some time ago I believe.  I
edited the category file manually, and restarted Gnus, then it works.
It would be nice if this was fixed...

Ok, I'll skip that. (Not that it should matter, but it makes
my gnus.el one line shorter :)

Yes there is. No groups seem to belong to it, though. I'll
change that instead of creating a new category.

Good. Then there's nothing wrong with my setup.

The complete contents of my ~/News/agent/lib/categories is:

((default true ignore))

Is this correct?

I think the "default" category applies to all groups not part of any
other category.

I dunno, my category file reads:

((default true nil nil))
((default (agent-predicate . true)))

And I think it downloads everything for me.

FWIW, my .emacs also include the following agent related settings:

 '(gnus-agent-consider-all-articles t)
 '(gnus-agent-enable-expiration (quote DISABLE))
 '(gnus-select-article-hook (quote (gnus-agent-fetch-selected-article ...

Change the ignore to nil.  This bug has been fixed in No Gnus.
I still need to back port it to the 5.10 branch.

Don't forget to "agentize" your server(s).  All of the categories,
etc. only apply to groups whose servers are "agentized".  Open the
server buffer (^ in the group buffer), select the appropriate server,
then enter "Ja".  You should see "(agent)" appear next to the server's
name.

You might also consider
 '(gnus-agent-mark-unread-after-downloaded t)

I didn't do this, but the agent seemed to download my
messages anyway with a `J s' in the group buffer. FWIW,
I'm using nnimap to read my mails.

Nnimap and nntp servers are agentized by default, if you start the
Agent for the very first time.  Look in the server buffer to verify
this, though.

The default category is a catch-all for all groups that have no other
category.  That is why there is no list of groups associated with it:
its usage is special-cased.

`e' for categories is broken in Gnus (at least in my version).

Opening the "Select member groups" thingy before pressing "Done"
might help. Or use `p' for editing the raw predicate.
