NAME

Dpkg::BuildFlags - query build flags

CONTENTS

DESCRIPTION

The Dpkg::BuildFlags object is used by dpkg-buildflags and can be used to query the same information.

FUNCTIONS

my $bf = Dpkg::BuildFlags->new() Create a new Dpkg::BuildFlags object. It will be initialized based on the value of several configuration files and environment variables.
$bf->load_vendor_defaults() Reset the flags stored to the default set provided by the vendor.
$bf->load_system_config() Update flags from the system configuration.
$bf->load_user_config() Update flags from the user configuration.
$bf->load_environment_config() Update flags based on user directives stored in the environment. See dpkg-buildflags(1) for details.
$bf->load_maintainer_config() Update flags based on maintainer directives stored in the environment. See dpkg-buildflags(1) for details.
$bf->load_config() Call successively load_system_config(), load_user_config(), load_environment_config() and load_maintainer_config() to update the default build flags defined by the vendor.
$bf->set($flag, $value, $source, $maint) Update the build flag $flag with value $value and record its origin as $source (if defined). Record it as maintainer modified if $maint is defined and true.
$bf->set_feature($area, $feature, $enabled) Update the boolean state of whether a specific feature within a known feature area has been enabled. The only currently known feature area is hardening.
$bf->strip($flag, $value, $source, $maint) Update the build flag $flag by stripping the flags listed in $value and record its origin as $source (if defined). Record it as maintainer modified if $maint is defined and true.
$bf->append($flag, $value, $source, $maint) Append the options listed in $value to the current value of the flag $flag. Record its origin as $source (if defined). Record it as maintainer modified if $maint is defined and true.
$bf->prepend($flag, $value, $source, $maint) Prepend the options listed in $value to the current value of the flag $flag. Record its origin as $source (if defined). Record it as maintainer modified if $maint is defined and true.
$bf->update_from_conffile($file, $source) Update the current build flags based on the configuration directives contained in $file. See dpkg-buildflags(1) for the format of the directives.

$source is the origin recorded for any build flag set or modified.

$bf->get($flag) Return the value associated to the flag. It might be undef if the flag doesn’t exist.
$bf->get_feature_areas() Return the feature areas (i.e. the area values has_features will return true for).
$bf->get_features($area) Return, for the given area, a hash with keys as feature names, and values as booleans indicating whether the feature is enabled or not.
$bf->get_origin($flag) Return the origin associated to the flag. It might be undef if the flag doesn’t exist.
$bf->is_maintainer_modified($flag) Return true if the flag is modified by the maintainer.
$bf->has_features($area) Returns true if the given area of features is known, and false otherwise. The only currently recognized area is hardening.
$bf->has($option) Returns a boolean indicating whether the flags exists in the object.
my @flags = $bf->list() Returns the list of flags stored in the object.

    Version 1.02

New methods: $bf->get_features(), $bf->has_features(), $bf->set_feature().

    Version 1.03

New method: $bf->get_feature_areas() to list possible values for $bf->get_features.

New method $bf->is_maintainer_modified() and new optional parameter to $bf->set(), $bf->append(), $bf->prepend(), $bf->strip().
