Patches in support of linking from org-mode

Patches in support of linking from org-mode

[david]

These two patches are pretty much independent. The first is needed by my 
work in progress patch for org-mode to provide links into notmuch 
(http://pivot.cs.unb.ca/git/?p=org-mode.git;a=shortlog;h=refs/heads/notmuch-link).

The second changes the interface of git-show to take the query-string
recently added explicitly as a parameter. This is more an aesthetic
thing, but it means that I don't have to call notmuch-show like
(let notmuch-query-search-string thread-id
     (notmuch-show thread-id))

Hope you like em. I also hope this whole git-send-email thing works out.

[PATCH 1/2] notmuch-search-process-filter: add text properties for authors and subject to each line

[david]

From: David Bremner <bremner@unb.ca>

Add functions notmuch-search-find-authors and notmuch-find-subject to
match notmuch-find-thread-id.  These functions are just a wrapper
around get-text-property, but in principle that could change.

[PATCH 2/2] notmuch-show: add optional argument for query context instead of using global binding notmuch-search-query-string

[david]

From: David Bremner <bremner@unb.ca>

Also modify the one call to notmuch-show in notmuch.el.  This makes
the call (notmuch-show thread-id) will work when there is no binding
for notmuch-search-query-string; e.g. when called from user code
outside notmuch.

[PATCH] notmuch-show-get-header: new function; return alist of parsed header fields.

[David Bremner]

This function parses the displayed message to recover header
fields. It uses mailheader.el to do the actual header parsing, after
preprocessing to remove indentation.  It relies on the variables
notmuch-show-message-begin-regexp, notmuch-show-header-begin-regexp,
and notmuch-show-message-end-regexp.
---

This is another patch needed for org-mode links. Really I just need
some way to get the author and subject of the current message in
notmuch-show-mode.  It seems like a generally useful function,
although of course it would be more efficient to cache these headers
somewhere if the function is being invoked many times.

[PATCH] notmuch.el: patch notmuch-show to call notmuch show without query-context (i.e. without tag:inbox) if the first query returns nothing.

[david]

From: David Bremner <bremner@unb.ca>

This fixes the annoying bug of archiving a thread, and then going back
to open it and getting an error.  It needs the notmuch-show API
changing patch of 1259979997-31544-3-git-send-email-david@tethera.net.
---

I'm not really expecting Carl to push this patch, because I think he
has a better solution in mind, but in the mean time maybe someone
finds it useful. It is saving my sanity already, since in wanderlust
 'a' = reply :).

On the contrary, David. I pushed this immediately, so thanks!

I'll still do the other solution, (other interfaces will want it), but
in the meantime, it's *really* nice to have this bug fixed.

I also fixed '+' and '-' to work in this same situation, (so you can
actually put an inbox tag *back* if you accidentally remove it). I
haven't yet fixed '*' for this case, so an accidental '* -inbox' won't
be recoverable with '* +inbox' if the current search is tag:inbox.

I've added a TODO item to fix this, (and the proposed fix there will
incidentally fix '*' to actually provide feedback on the added/removed
tags too, which will also help).

Hi David,

Somehow I had this mail from you on my backlog of patches to review, but
it looks like everything here has already been applied. So thanks!

And please let me know if you need any further changes to notmuch to
make it work better with org-mode. (A recent message on this list does
make me very interested to try out org-mode and to make sure it
integrates well with notmuch.)

The last patches needed for initial org-mode support are 
    id:1267015920-8999-1-git-send-email-david@tethera.net
    (notmuch-query.el)

    and

    1265773528-30794-1-git-send-email-david@tethera.net 
    (emacs subdirectory)

The first is needed by the code which creates links to notmuch
threads. Since threads are mutable, what it does turn a thread-id into a
list of message-ids.  

All the best,

David
