notmuch-mutt: Notmuch (of a) helper for Mutt
============================================
notmuch-mutt provide integration among the [Mutt] [1] mail user agent and the
[Notmuch] [2] mail indexer.
notmuch-mutt offer two main integration features. The first one is the ability
of stating a **search query interactively** and then jump to a fresh Maildir
containing its search results only. The second one is the ability to
**reconstruct threads on the fly** starting from the currently highlighted
mail, which comes handy when a thread has been split across different maildirs,
archived, or the like.
notmuch-mutt enables to trigger mail searches via a Mutt macro (usually F8) and
reconstruct threads via another (usually F9). Check the manpage for the 2-liner
configuration snippet for your Mutt configuration files (~/.muttrc,
/etc/Muttrc, or a /etc/Muttrc.d snippet).
A [blog style introduction] [3] to notmuch-mutt is available and includes some
more rationale for its existence.
Arguably, some of the logics of notmuch-mutt could disappear by adding support
for a --output=symlinks flag to notmuch.

Requirements
------------
To *run* notmuch-mutt you will need Perl with the following libraries:
- Mail::Box <http://search.cpan.org/~markov/Mail-Box/>
(Debian package: libmail-box-perl)
- Mail::Internet <http://search.cpan.org/~markov/MailTools/>
(Debian package: libmailtools-perl)
- String::ShellQuote <http://search.cpan.org/~rosch/String-ShellQuote/ShellQuote.pm>
(Debian package: libstring-shellquote-perl)
- Term::ReadLine <http://search.cpan.org/~hayashi/Term-ReadLine-Gnu/>
(Debian package: libterm-readline-gnu-perl)
To *build* notmuch-mutt documentation you will need:
- pod2man (coming with Perl) to generate the manpage
- markdown to generate README.html out of this file

=head1 NAME
notmuch-mutt - notmuch (of a) helper for Mutt
=head1 SYNOPSIS
=over
=item B<notmuch-mutt> [I<OPTION>]... search [I<SEARCH-TERM>]...
=item B<notmuch-mutt> [I<OPTION>]... thread < I<MAIL>
=item B<notmuch-mutt> [I<OPTION>]... tag [I<TAGS>]... < I<MAIL>
=back
=head1 DESCRIPTION
notmuch-mutt is a frontend to the notmuch mail indexer capable of populating
maildir with search results.
=head1 OPTIONS
=over 4
=item -o DIR
=item --output-dir DIR
Store search results as (symlink) messages under maildir DIR. Beware: DIR will
be overwritten. (Default: F<~/.cache/notmuch/mutt/results/>)
=item -p
=item --prompt
Instead of using command line search terms, prompt the user for them (only for
"search").
=item -h
=item --help
Show usage information and exit.
=back
=head1 INTEGRATION WITH MUTT
notmuch-mutt can be used to integrate notmuch with the Mutt mail user agent
(unsurprisingly, given the name). To that end, you should define macros like
the following in your Mutt configuration (usually one of: F<~/.muttrc>,
F</etc/Muttrc>, or a configuration snippet under F</etc/Muttrc.d/>):
macro index <F8> \
"<enter-command>unset wait_key<enter><shell-escape>notmuch-mutt --prompt search<enter><change-folder-readonly>~/.cache/notmuch/mutt/results<enter>" \
"notmuch: search mail"
macro index <F9> \
"<enter-command>unset wait_key<enter><pipe-message>notmuch-mutt thread<enter><change-folder-readonly>~/.cache/notmuch/mutt/results<enter><enter-command>set wait_key<enter>" \
"notmuch: reconstruct thread"
macro index <F6> \
"<enter-command>unset wait_key<enter><pipe-message>notmuch-mutt tag -inbox<enter>" \
"notmuch: remove message from inbox"
The first macro (activated by <F8>) prompts the user for notmuch search terms
and then jump to a temporary maildir showing search results. The second macro
(activated by <F9>) reconstructs the thread corresponding to the current mail
and show it as search results. The third macro (activated by <F6>) removes the
tag C<inbox> from the current message; by changing C<-inbox> this macro may be
customised to add or remove tags appropriate to the users notmuch work-flow.
To keep notmuch index current you should then periodically run C<notmuch
new>. Depending on your local mail setup, you might want to do that via cron,
as a hook triggered by mail retrieval, etc.
