Agent: visual feedback about downloaded articles

Agent: visual feedback about downloaded articles

[Kai Großjohann]

I would like to have some visual feedback about articles that are
downloaded, even when plugged.  Is it possible to have a character in
the summary line for each article?

So no one wanna take this on?  Or it has been done?

I've done it.  Please try it to see whether it prints meaningful
things.

(defun kai-gnus-article-downloaded-p (header)
  "Say whether ARTICLE has been downloaded or not."
  (cdr (assq (aref header 0) gnus-agent-article-alist)))

(add-to-list 'gnus-summary-line-format-alist
	     '(?+ (if (kai-gnus-article-downloaded-p gnus-tmp-header)
		      "+" "-")
		  ?s))

After these lines, you can add %+ in gnus-summary-line-format.

it works...sort of.

After setting that up, all my articles were indicated as "-" (not
downloaded) when indeed they have been (I manually looked at the agent
caches dir and found the download articles.)

However, after I select an article, quit the summary buffer and reenter, the
previously selected article is now indicated as downloaded.  I use
gnus-agent-fetch-selected-article in gnus-select-article-hook.

Hm.  Are these mentioned in the .agentview file in the directory?
Are they mentioned in the .overview file there?

I found out that my some of my .overview files in the agent dir have
duplicated entries (multiple lines with exact content) as a result of (setq
gnus-agent-consider-all-articles t) always fetches read articles.

Do you think the duplicate lines come from
gnus-agent-consider-all-articles?

I'm hoping that this was because of old implementations and that the
current implementation does not add additional dupes.

How to deal with the existing dupes, though?

I only observed my .overview file size explosions since last week.  It may
or may not be related to gnus-agent-consider-all-articles.

Unfortunately, I have to remove .overview and do 'J u' on the group again.

Okay.  And does the .overview explode again after you do this?
