Dpkg::BuildFlags.3perl - Man Page

This class is used by dpkg-buildflags and can be used to query the same information.

$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.

$bf->unset($flag)

Unset the build flag $flag, so that it will not be known anymore.

$bf->set($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 areas are “future”, “qa”, “sanitize”, “optimize”, “hardening” and “reproducible”.

$bf->strip($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 feature areas are “future”, “qa”, “sanitize”, “hardening” and “reproducible”.

$bf->has($option)

Returns a boolean indicating whether the flags exists in the object.

@flags = $bf->list()

Returns the list of flags stored in the object.
