NAME
Dpkg::BuildFlags - query build flags
DESCRIPTION
This class is used by dpkg-buildflags and can be used to query the same
information.
METHODS
$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", "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.
CHANGES
Version 1.04 (dpkg 1.20.0)
New method: $bf->unset().
Version 1.03 (dpkg 1.16.5)
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().
Version 1.02 (dpkg 1.16.2)
New methods: $bf->get_features(), $bf->has_features(),
$bf->set_feature().
Version 1.01 (dpkg 1.16.1)
New method: $bf->prepend() very similar to append(). Implement support
of the prepend operation everywhere.
