The build types are bit constants that are exported by default. Multiple types can be ORed. B<Note>: This is a private module, its API can change at any time. =cut package Dpkg::BuildTypes 0.02; use strict; use warnings; our @EXPORT = qw( BUILD_DEFAULT BUILD_SOURCE BUILD_ARCH_DEP BUILD_ARCH_INDEP BUILD_BINARY BUILD_FULL build_has_any build_has_all build_has_none build_is set_build_type set_build_type_from_options set_build_type_from_targets get_build_options_from_type ); use Exporter qw(import); use Dpkg::Gettext; use Dpkg::ErrorHandling; =head1 CONSTANTS =over 4 =item BUILD_DEFAULT This build is the default. =item BUILD_SOURCE This build includes source artifacts. =item BUILD_ARCH_DEP This build includes architecture dependent binary artifacts. =item BUILD_ARCH_INDEP This build includes architecture independent binary artifacts. =item BUILD_BINARY This build includes binary artifacts. =item BUILD_FULL This build includes source and binary artifacts. =cut # Simple types. use constant { BUILD_DEFAULT => 1, BUILD_SOURCE => 2, BUILD_ARCH_DEP => 4, BUILD_ARCH_INDEP => 8, }; # Composed types. use constant BUILD_BINARY => BUILD_ARCH_DEP | BUILD_ARCH_INDEP; use constant BUILD_FULL => BUILD_BINARY | BUILD_SOURCE; my $current_type = BUILD_FULL | BUILD_DEFAULT; my $current_option = undef; my @build_types = qw(full source binary any all); my %build_types = ( full => BUILD_FULL, source => BUILD_SOURCE, binary => BUILD_BINARY, any => BUILD_ARCH_DEP, all => BUILD_ARCH_INDEP, ); my %build_targets = ( 'clean' => BUILD_SOURCE, 'build' => BUILD_BINARY, 'build-arch' => BUILD_ARCH_DEP, 'build-indep' => BUILD_ARCH_INDEP, 'binary' => BUILD_BINARY, 'binary-arch' => BUILD_ARCH_DEP, 'binary-indep' => BUILD_ARCH_INDEP, ); =back =head1 FUNCTIONS =over 4 =item build_has_any($bits) Return a boolean indicating whether the current build type has any of the specified $bits. =cut sub build_has_any { my ($bits) = @_; return $current_type & $bits; } =item build_has_all($bits) Return a boolean indicating whether the current build type has all the specified $bits. =cut sub build_has_all { my ($bits) = @_; return ($current_type & $bits) == $bits; } =item build_has_none($bits) Return a boolean indicating whether the current build type has none of the specified $bits. =cut sub build_has_none { my ($bits) = @_; return !($current_type & $bits); } =item build_is($bits) Return a boolean indicating whether the current build type is the specified set of $bits. =cut sub build_is { my ($bits) = @_; return $current_type == $bits; } =item set_build_type($build_type, $build_option, %opts) Set the current build type to $build_type, which was specified via the $build_option command-line option.
