Dpkg::BuildFlags - query build flags
The Dpkg::BuildFlags object is used by dpkg-buildflags and can be used to query the same information.
Create a new Dpkg::BuildFlags object. It will be initialized based on the value of several configuration files and environment variables.
Reset the flags stored to the default set provided by the vendor.
Update flags from the system configuration.
Update flags from the user configuration.
Update flags based on user directives stored in the environment. See dpkg-buildflags(1) for details.
Update flags based on maintainer directives stored in the environment. See dpkg-buildflags(1) for details.
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.
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.
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".
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.
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.
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.
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.
Return the value associated to the flag. It might be undef if the flag doesn't exist.
Return the feature areas (i.e. the area values has_features will return true for).
Return, for the given area, a hash with keys as feature names, and values as booleans indicating whether the feature is enabled or not.
Return the origin associated to the flag. It might be undef if the flag doesn't exist.
Return true if the flag is modified by the maintainer.
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".
Returns a boolean indicating whether the flags exists in the object.
Returns the list of flags stored in the object.
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().
New methods: $bf->get_features(), $bf->has_features(), $bf->set_feature().
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.
Mark the module as public.
