| | =head1 NAME
lei-p2q - use a patch to generate a lei-q query
=head1 SYNOPSIS
lei p2q [OPTIONS] (FILE|COMMIT)
lei p2q [OPTIONS] (--stdin|-)
=head1 DESCRIPTION
Given a patch, create a query that can be fed on stdin to L<lei-q(1)>.
This is useful for mapping the patch to associated messages of an
inbox.
The patch can be provided on stdin or as a file. Alternatively, when
an argument is given that does not point to an existing file, it is
taken as a reference to a commit in the current repository, and
L<git-format-patch(1)> is used to generate the patch.
=head1 OPTIONS
=over
=item -w PREFIX[,PREFIX], --want=PREFIX[,PREFIX]
Search prefixes to use. C<dfpost> (post-image git blob ID) and C<dfn>
(file names from the diff) are the most useful. Other available
values are C<dfa>, C<dfb>, C<dfctx>, C<dfhh>, and C<dfpre>.
=for comment
TODO: Put a table of prefixes somewhere and reference that (at least
here and in lei-q)?
Appending an integer to C<dfpost> or C<dfpre> indicates a minimum ID
length, and the generated query will be for that value up through the
default abbreviation length. For example, if the repository's
C<core.abbrev> is set to C<auto> and git calculates the default
abbreviation length as 7, C<dfpost6> will expand a post-image blob ID
of e7b4b32 (seven characters) into C<dfpost:e7b4b32 OR dfpost:e7b4b3>.
This option may be given multiple times.
Default: C<dfpost7>
=item --stdin
Read patch from stdin.
=item --debug
Dump output that shows the information collected for every prefix.
This information can be useful for seeing how a patch is processed,
but the format should not be considered stable.
=item -q, --quiet
Suppress feedback messages.
