X-BeenThere: notmuch@notmuchmail.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: "Use and development of the notmuch mail system." List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 24 Feb 2010 12:57:04 -0000 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. This patch relies on the emacs directory patch of <1265773528-30794-1-git-send-email-david@tethera.net> --- This version is rebased against the json patches that eventually made it into master. Oddly, no actual changes were required based on Carl's change of "id" to "thread". Some trailing whitespace was also removed. emacs/Makefile.local | 3 +- emacs/notmuch-query.el | 89 ++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 91 insertions(+), 1 deletions(-) create mode 100644 emacs/notmuch-query.el diff --git a/emacs/Makefile.local b/emacs/Makefile.local index c6ca142..6c87a60 100644 --- a/emacs/Makefile.local +++ b/emacs/Makefile.local @@ -1,6 +1,7 @@ dir=emacs emacs_sources= \ - $(dir)/notmuch.el + $(dir)/notmuch.el \ + $(dir)/notmuch-query.el emacs_bytecode=$(subst .el,.elc,$(emacs_sources)) diff --git a/emacs/notmuch-query.el b/emacs/notmuch-query.el new file mode 100644 index 0000000..86230ba --- /dev/null +++ b/emacs/notmuch-query.el @@ -0,0 +1,89 @@ +; notmuch.el --- run notmuch within emacs +; +; Copyright © David Bremner +; +; This file is part of Notmuch. +; +; Notmuch is free software: you can redistribute it and/or modify it +; under the terms of the GNU General Public License as published by +; the Free Software Foundation, either version 3 of the License, or +; (at your option) any later version. +; +; Notmuch is distributed in the hope that it will be useful, but +; WITHOUT ANY WARRANTY; without even the implied warranty of +; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
