Dpkg::BuildFlags − query build flags
The Dpkg::BuildFlags object is used by dpkg-buildflags and can be used to query the same information.
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
1.01
New method: $bf−>prepend() very
similar to append(). Implement support of the prepend
operation everywhere.
New method: $bf−>load_maintainer_config() that update the build flags based on the package maintainer directives.
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().
