Dpkg::Arch - handle architectures

Version1.03(dpkg1.19.1) New argument: Accept a "positive" option in debarch_is_illegal() and debarch_list_parse(). Version1.02(dpkg1.18.19) New import tags: ":all", ":getters", ":parsers", ":mappers", ":operators". Version1.01(dpkg1.18.5) New functions: debarch_is_illegal(), debarch_list_parse(). Version1.00(dpkg1.18.2) Mark the module as public.

The Dpkg::Arch module provides functions to handle Debian architectures, wildcards, and mapping from and to GNU triplets. No symbols are exported by default. The :all tag can be used to import all symbols. The :getters, :parsers, :mappers and :operators tags can be used to import specific symbol subsets.

$arch = get_raw_build_arch() Get the raw build Debian architecture, without taking into account variables from the environment. $arch = get_build_arch() Get the build Debian architecture, using DEB_BUILD_ARCH from the environment if available. $arch = get_raw_host_arch() Get the raw host Debian architecture, without taking into account variables from the environment. $arch = get_host_arch() Get the host Debian architecture, using DEB_HOST_ARCH from the environment if available. @arch_list = get_valid_arches() Get an array with all currently known Debian architectures. $multiarch = gnutriplet_to_multiarch($gnutriplet) Map a GNU triplet into a Debian multiarch triplet. $multiarch = debarch_to_multiarch($arch) Map a Debian architecture into a Debian multiarch triplet. $gnutriplet = debarch_to_gnutriplet($arch) Map a Debian architecture into a GNU triplet. $arch = gnutriplet_to_debarch($gnutriplet) Map a GNU triplet into a Debian architecture. $bool = debarch_eq($arch_a, $arch_b) Evaluate the equality of a Debian architecture, by comparing with another Debian architecture. No wildcard matching is performed. $bool = debarch_is($arch, $arch_wildcard) Evaluate the identity of a Debian architecture, by matching with an architecture wildcard. $bool = debarch_is_wildcard($arch) Evaluate whether a Debian architecture is an architecture wildcard. $bool = debarch_is_illegal($arch, %opts) Validate an architecture name. Options: positive If set to a true value, only positive architectures will be accepted, otherwise negated architectures are allowed. $bool = debarch_is_concerned($arch, @arches) Evaluate whether a Debian architecture applies to the list of architecture restrictions, as usually found in dependencies inside square brackets. @array = debarch_list_parse($arch_list, %opts) Parse an architecture list. Options: positive If set to a true value, only positive architectures will be accepted, otherwise negated architectures are allowed.
