=head1 NAME
mutt-notmuch - notmuch (of a) helper for Mutt
=head1 SYNOPSIS
=over
=item B<mutt-notmuch> [I<OPTION>]... search [I<SEARCH-TERM>]...
=item B<mutt-notmuch> [I<OPTION>]... thread < I<MAIL>
=back
=head1 DESCRIPTION
mutt-notmuch 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/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
mutt-notmuch can be used to integrate notmuch with the Mutt mail user agent
(unsurprisingly, given the name). To that end, you should define the following
macros in your F<~/.muttrc> (replacing F<~/bin/mutt-notmuch> for the actual
location of mutt-notmuch on your system):
macro index <F8> \
"<enter-command>unset wait_key<enter><shell-escape>~/bin/mutt-notmuch --prompt search<enter><change-folder-readonly>~/.cache/mutt_results<enter>" \
"search mail (using notmuch)"
macro index <F9> \
"<enter-command>unset wait_key<enter><pipe-message>~/bin/mutt-notmuch thread<enter><change-folder-readonly>~/.cache/mutt_results<enter><enter-command>set wait_key<enter>" \
"search and reconstruct owning thread (using notmuch)"
The first macro (activated by <F8>) will prompt the user for notmuch search
terms and then jump to a temporary maildir showing search results. The second
macro (activated by <F9>) will reconstruct the thread corresponding to the
current mail and show it as search results.
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.
