gmail label support in offlineimap - update

Hi

there is a patched version of offlineimap available which is synching gmail labels to x-keywords.
More information can be found here:

http://thread.gmane.org/gmane.mail.imap.offlineimap.general/5943/focus=5970

and

http://article.gmane.org/gmane.mail.imap.offlineimap.general/5970

It is written by Abdó ig-Maranges (I cc him this email).

I would ask if it is possible (and desired) to include indexing of the X-keywords headers as well,
so that gmail labels can be represented as tags in notmuch.

To have sync from notmuch tags to gmail labels, the tags would have to be written to a x-header as
well.

This could possibly be activated by a config setting, so that emails are left unchanged by
default, but if write.Tags.In.X-Header is set to TRUE, the tags are synced to the x-headers as well.

Unfortunately, I am not a programmer, it is only that I really like notmuch and would like to
continue using it with gmail label sync.

I think this would be a very useful feature.

Cheers,

Rainer

As far as syncing flags to notmuch, it sounds like this would be easy to
achieve with an independent 3rd tool, or even a small script:
1) Find files in the maildir modified since the last check
2) Read their keywords headers
3) Update the notmuch tags accordingnly.

The other direction sounds like it would be trickier though, since there's
no obvious way to say "what notmuch tags have changed since time X?". Is
this something that notmuch could provide?

Alternatively, would it be a good idea to give notmuch a tags-changed hook,
so that an external tool could be called on a tag change? That sounds like
would solve this problem, keep the gmail/imap logic safely away from
notmuch, and probably provide some really interesting other opportunities
for automation of things by tags.

Not currently, but there have been patches proposed; see e.g.

    id:1323796305-28789-1-git-send-email-schnouki@schnouki.net

I think a "tag changed hook" could solve both problems - when there would be an additional "messge
changed" hook: the "message changed" hook could be used to add the x-headers to the notmuch
database, and the "tag changed" hook could do the inverse, i.e. update the x-headers in the message.

This would be a clean approach, which could be used for many things.

Cheers,

Rainer

How would you make the “message changed” hook work? What if I do
“$EDITOR <some-mail>”? What is supposed to trigger the hook?

The hook would be triggered when doing "notmuch new". Cling the hook from a different program is
not feasible, I guess, unless opne can configure the external program accordingly.

One could parse the X-Labels header and compare it with actual tags
given message has.  If there are some tags that X-Labels lists but the
message does not have, the notmuch->gmail syncing tool could assume that
those were removed by notmuch.  Similarly with tags that are not in
X-Labels but the message has.  (Of course the list of tags would have to
be limited to those that have corresponding gmail labels.)  Just
a thought.

Assumptions are dangerous - what about labels added on gmail side?
