Hi Aneesh,

I'm sorry this patch has lingered so long without comment. There's
really only one problem I see with it:

> +(defcustom notmuch-search-result-format nil
> +  "Search result formating. Supported fields are
> + date, count, authors, subject, tags
> +ex: (setq notmuch-search-result-format \(\(\"authors\" . \"%-40s\"\)

> +:group 'notmuch)

...

I don't like that the new format variable is nil by default and then
there's an open-coded implementation of the default formatting. This has
a couple of problems:

1. The new code is not being exercised by default, so it would be easy
   to break it without realizing.

2. The system is not very self-documenting.

   If a new user wants to tweak the default format, that will be a lot
   easier if they find a customizable variable that describes the
   current format. *That* will be a lot easier to modify rather than
   trying to learn what should be used instead of "nil".

[notmuch] [PATCH -V2] notmuch.el: Support for customizing search result display

2010-01-23 Thread Aneesh Kumar K.V
From: Aneesh Kumar K.V 

This patch helps in customizing search result display
similar to mutt's index_format. The customization is done
by defining an alist as below

(setq notmuch-search-result-format '(("date" . "%s ")
 ("authors" . "%-40s ")
 ("subject" . "%s ")
 ("tags" . "(%s)")))

The supported keywords are date, count, authors, subject and tags.

Changes from V1:
tags can be specified any where in the result format.
Dropped notmuch-tag-face-alist which implies we cannot
fontify select list of tag names.
