=head1 NAME
dh_quilt_patch - apply patches listed in debian/patches/series
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_quilt_patch> [S<I<debhelper options>>]
=head1 DESCRIPTION
dh_quilt_patch simply calls B<quilt push -a> after having set
the environment variable B<QUILT_PATCHES> to B<debian/patches>.
All patches listed in B<debian/patches/series> are then applied in the
current directory. The command does not fail if the patches have
already been applied.
If the file B<debian/patches/series> does not exist or is empty,
dh_quilt_patch returns without doing anything.
You can use another directory instead of B<debian/patches> by setting
(and exporting) the environment variable B<QUILT_PATCH_DIR>.
=head1 EXAMPLES
dh_quilt_patch is usually called indirectly in a rules file via the
dh command.
%:
dh $@ --with quilt
It can also be direcly called at the start of the build (or configure)
rule.
build:
dh_quilt_patch
./configure
$(MAKE)
=cut
init();
$ENV{"QUILT_PATCHES"} = $ENV{"QUILT_PATCH_DIR"} ?
$ENV{"QUILT_PATCH_DIR"} : "debian/patches";
# Since v0.67, quilt returns the error code 1 instead of 2,
# if the series file does not exist or is empty.
# So check if the series file contains data before
# running quilt to avoid returning an error.
# See Debian bug reports #1030781, #1053444, #1053500 for details.
if ( -s $ENV{"QUILT_PATCHES"} . "/series" ) {
complex_doit('quilt --quiltrc /dev/null push -a || test $? = 2');
}
=head1 NOTES
This tool is useless if you use the source package format B<3.0 (quilt)>.
Consider switching to this source format if you haven't done it yet.
=head1 SEE ALSO
L<debhelper(7)>, L<dh(1)>.
This program is meant to be used together with debhelper.
