;;; Commentary:
|
|
|
|
;; This is a back end for using the mairix search engine with
|
|
;; Gnus. Mairix is a tool for searching words in locally stored
|
|
;; mail. Mairix is very fast which allows using it efficiently for
|
|
;; "smart folders", e.g. folders which are associated with search
|
|
;; queries. Of course, you can also use this back end just for
|
|
;; calling mairix with some search query.
|
|
;;
|
|
;; Mairix is written by Richard Curnow. More information can be found at
|
|
;; http://www.rpcurnow.force9.co.uk/mairix/
|
|
|
|
;; Commentary on the code: nnmairix sits between Gnus and the "real"
|
|
;; back end which handles the mail (currently nnml, nnimap and
|
|
;; nnmaildir were tested). I know this is all a bit hacky, but so far
|
|
;; it works for me. This is the first back end I've written for Gnus,
|
|
;; so I'd appreciate any comments, suggestions, bug reports (and, of
|
|
;; course, patches) for improving nnmairix.
|
|
|
|
;; nnmairix does not use an active file, since I wanted to contain the
|
|
;; back end "inside Gnus" as much as possible without the need of an
|
|
;; external file. It stores the query/folder information in the group
|
|
;; parameters instead. This also implies that once you kill a mairix
|
|
;; group, it's gone for good. I don't think that this is really
|
|
;; problematic, since I don't see the need in unsubscribing and
|
|
;; re-subscribing search groups
|
|
|
|
;; Every mairix server is "responsible" for one mairix installation,
|
|
;; i.e. you can have several mairix servers for different mairix
|
|
;; configurations. Not that I think anyone will actually do this, but
|
|
;; I thought it would be a "nice to have feature"...
|
|
|
|
;; KNOWN BUGS:
|
|
;; * Mairix does only support us-ascii characters.
|
|
|
|
;; TODO/MISSING FEATURES:
|
|
;; * Support of more back ends (nnmh, nnfolder, nnmbox...)?
|
|
;; * Maybe use an active file instead of group parameters?
|
|
;; * Maybe use "-a" when updating groups which are not newly created?
|
|
|
|
;;; Changelog:
|
|
;; 05/30/2008 - version 0.6
|
|
;;
|
|
;; * It is now possible to propagate marks from the nnmairix groups
|
|
;; to the original messages (and for maildir also vice versa). See
|
|
;; the docs for details on this feature - it's pretty delicate
|
|
;; and currently needs a patched mairix binary to work smoothly.
|
|
;;
|
|
;; * Keep messages in nnmairix groups always read/unread
|
|
;; (bound to 'G b r').
|
|
;;
|
|
;; * Recreate back end folder for nnmairix groups in case you
|
|
;; somehow get wrong article counts (bound to 'G b d').
|
|
;;
|
|
;; * New group parameter 'allow-fast'. Toggling of parameter bound
|
|
;; to 'G b a'. The default is nil, meaning that the group will
|
|
;; always be updated with a mairix search, even when only entered.
|
|
;;
|
|
;; * More/Better use of the registry (if available). Can now also
|
|
;; deal with duplicate messages in different groups.
|
|
;;
|
|
;; 02/06/2008 - version 0.5
|
|
;;
|
|
;; * New function: nnmairix-goto-original-article. Uses the
|
|
;; registry or the mail file path for determining original group.
|
|
;;
|
|
;; * Deal with empty Xref header
|
|
;;
|
|
;; * Changed summary mode keybindings since the old ones were
|
|
;; already taken
|
|
;;
|
|
;; (Thanks to Tassilo Horn and Ted Zlatanov for their help)
|
|
;;
|
|
;; 01/07/2008 - version 0.4
|
|
;;
|
|
;; * New/fixed doc strings and code cleanup.
|
|
;;
|
|
;; 11/18/2007 - version 0.3
|
|
;;
|
|
;; * Fixed bugs when dealing with nnml and native servers
|
|
;;
|
|
;; * Make variables customizable
|
|
;;
|
|
;; 10/10/2007 - version 0.2
|
|
;;
|
|
;; * Use nnml-directory/directory server variables for nnml and
|
|
;; nnmaildir back ends as path for search folders. This way it
|
|
;; becomes independent of 'base' setting in .mairixirc (but not for
|
|
;; nnimap).
|
|
;;
|
|
;; * As a result: Changed nnmairix-backend-to-server so that user
|
|
;; is asked when more than one nnmairix server exists and we do not
|
|
;; know which one is responsible for current back end.
|
|
;;
|
|
;; * Rename files when using nnml back ends so that there are no
|
|
;; holes in article numbers. This should fix all problems regarding
|
|
;; wrong article counts with nnml.
|
|
;;
|
|
;; * More commands for creating queries (using widgets or the
|
|
;; minibuffer).
|
|
;;
|
|
;; * Fixed bug in nnmairix-create-search-group-from-message
|
|
;;
|
|
;; * Changed copyright to FSF
|
|
;;
|
|
;; (Thanks to Georg C. F. Greve and Bastien for suggestions and
|
|
;; ideas!)
