Should this comment prefix be ';;'? A single ';' is indented way over to
the right by default.

There are a bunch of spurious blank lines in various places.

Notmuch release 0.1 now available

[Carl Worth]

In trying to get notmuch to grow up a little bit, I've just added a
version number (0.1 initially) and have started doing releases. My idea
for now is to have 2-part versions for releases, and 3-part versions to
indicate intermediate states within git.

For example, I just released notmuch 0.1, current git clone will
create notmuch 0.1.1, and the next anticipated release will be 0.2.

The first release announcement is below, with very thin release notes. I
hope to have better release announcements in the future. For this, I'll
need the help of all contributors. Here's my request:

When you submit a patch adding a new feature to notmuch, please
include with it an edit to the NEWS file adding a sentence or
paragraph to the top of that file.

Thanks, and have fun out there.

-Carl

Where to obtain notmuch 0.1
===
  http://notmuchmail.org/releases/notmuch-0.1.tar.gz

Which can be verified with:

  http://notmuchmail.org/releases/notmuch-0.1.tar.gz.sha1
  fa390b7e652bebbdd5c178a60d8056e662df03ba  notmuch-0.1.tar.gz

  http://notmuchmail.org/releases/notmuch-0.1.tar.gz.sha1.asc
  (signed by Carl Worth)

What's new in notmuch 0.1
=
This is the first release of the notmuch mail system.

It includes the libnotmuch library, the notmuch command-line
interface, and an emacs-based interface to notmuch.

Note: Notmuch will work best with Xapian 1.0.18 (or later) or Xapian
1.1.4 (or later). Previous versions of Xapian (whether 1.0 or 1.1) had
a performance bug that made notmuch very slow when modifying
tags. This would cause distracting pauses when reading mail while
notmuch would wait for Xapian when removing the "inbox" and "unread"
tags from messages in a thread.

What is notmuch
===
Notmuch is a system for indexing, searching, reading, and tagging
large collections of email messages in maildir or mh format. It uses
the Xapian library to provide fast, full-text search with a convenient
search syntax.

We actually realized with spaetz that we duplicated work on this one... I
also have a vapi file, which is working pretty well so far (I've used
almost all the functions in it). I guess we should merge them, and include
the result in notmuch's tree.

Now I use "lbdb", which gets very slow as time goes. You idea creates a

As it happens, some of us already are interested.

As soon as automatic gobject introspection based language bindings
become workable for at least python and perl, my plan is to rewrite
buffy[1] in Vala.

A second plan would be to have buffy show stats for saved notmuch
queries as well as (or instead of) mail folders.

It's very nice to know I wouldn't be the only person playing with Vala
around here.

[notmuch] vala, this is notmuch. notmuch, this is vala

[Sebastian Spaeth]

I really want to replace my address book with dynamic notmuch searches
and while python gives me those in 0.3 seconds or so, I wanted better.

So I bound notmuch.so to vala (at least what I needed) and played with
the code a bit. The resulting 100 lines of vala code are here:

http://github.com/spaetz/vala-notmuch/tree/master/src

For those without vala, this is the generated C file which can be
compiled with './make' in the same directory:

http://github.com/spaetz/vala-notmuch/blob/static-sources/src/notmuch.c

Usage: "./vnotmuch Seb" will output all 'to:' addresses according to
frequency for all messages where to, cc, or bcc matches "Seb*". It also
filters with AND "from:yourprimarymailaddress". Just
"./vnotmuch" outputs all addresses that you ever sent mails to. It never
writes/modifies your db.

The only output you get are the lowercased email addresses and the
frequency, no names are preserved/output.

It is fast. This is my "./vnotmuch Seb" search over 14.5k mails with
857 mails from my primary account:
real0m0.026s
user0m0.000s
sys 0m0.020s

Just a teaser to make you interested in vala :).

[notmuch] [PATCH v3] notmuch-query.el: new file to support access to the notmuch database.

[da...@tethera.net]

From: David Bremner 

Initially this file provides one main function
notmuch-query-get-threads, which takes a set of search terms, and
returns a parsed set of matching threads as a lisp data structure.

A set of notmuch-query-map-* functions are provided to help map
functions over the data structure.

The function notmuch-query-get-message-ids uses this machinery to get
the set of message-ids matching a query.

Commentary on this revision of the patch.
- Rebased to current master.

Very interesting stuff. Yes, please let me know when things are merged
and I'll be glad to carry this in the notmuch repository.

Very nice stuff indeed. I incorporated the two minor style issues that
David E. mentioned in his reply. I do think that
"notmuch-query-get-threads" would be better named something much closer
to "notmuch-search". But we can wait to clear up the naming until we get
everything switched to this and the old calls to "notmuch search"
removed.

Thank you. It worked perfectly though it is not mentionned that
you have to do the search *first* and press the '*' then after. I
would have thought to do a "all-in-one-operation" -i.e press the
* key, enter a search criteria and enter a list of tags -.

[notmuch] Debian package update ?

Hi,

I feel like being far behind master with my current (official)

?

I know I was given instructions to build my own from the Git
repository but I am still stuck and I did not get any success in
doing so :/

Sounds reasonable enough. When I coded this, there was no official
library version yet, so searching for the latest sounded useful
enough. Now that we have an official shared lib, I'm just going to apply
your patch.

[notmuch] vala, this is notmuch. notmuch, this is vala

[Sebastian Spaeth]

I really want to replace my address book with dynamic notmuch searches
and while python gives me those in 0.3 seconds or so, I wanted better.

So I bound notmuch.so to vala (at least what I needed) and played with
the code a bit. The resulting 100 lines of vala code are here:

http://github.com/spaetz/vala-notmuch/tree/master/src

For those without vala, this is the generated C file which can be
compiled with './make' in the same directory:

http://github.com/spaetz/vala-notmuch/blob/static-sources/src/notmuch.c

Usage: ./vnotmuch Seb will output all 'to:' addresses according to
frequency for all messages where to, cc, or bcc matches Seb*. It also
filters with AND from:yourprimarymailaddress. Just
./vnotmuch outputs all addresses that you ever sent mails to. It never
writes/modifies your db.

The only output you get are the lowercased email addresses and the
frequency, no names are preserved/output.

It is fast. This is my ./vnotmuch Seb search over 14.5k mails with
857 mails from my primary account:
real0m0.026s
user0m0.000s
sys 0m0.020s

Just a teaser to make you interested in vala :).

Now I use lbdb, which gets very slow as time goes. You idea creates a

As it happens, some of us already are interested.

As soon as automatic gobject introspection based language bindings
become workable for at least python and perl, my plan is to rewrite
buffy[1] in Vala.

A second plan would be to have buffy show stats for saved notmuch
queries as well as (or instead of) mail folders.

It's very nice to know I wouldn't be the only person playing with Vala
around here.

 There's also a simple update to tell git to ignore notmuch-shared.

Thanks. This is pushed.

[notmuch] [PATCH v3] notmuch-query.el: new file to support access to the notmuch database.

[david]

From: David Bremner brem...@unb.ca

Initially this file provides one main function
notmuch-query-get-threads, which takes a set of search terms, and
returns a parsed set of matching threads as a lisp data structure.

A set of notmuch-query-map-* functions are provided to help map
functions over the data structure.

The function notmuch-query-get-message-ids uses this machinery to get
the set of message-ids matching a query.
---

Commentary on this revision of the patch.
- Rebased to current master.
- Last time I checked, used by dme's json rewrite of the emacs ui
- Warnings eliminated by including the new notmuch-lib.el

Thanks, David.

(And thanks also, to David Bremner for providing a version with
cleaned-up whitespace issues.)

This is pushed now.

PS. David, (Edmonson), putting the actual patch into the email message
is preferred. That lets me reply for any review necessary, and also
apply the patch when reading email when not online.

Very nice stuff indeed. I incorporated the two minor style issues that
David E. mentioned in his reply. I do think that
notmuch-query-get-threads would be better named something much closer
to notmuch-search. But we can wait to clear up the naming until we get
everything switched to this and the old calls to notmuch search
removed.
