NAME

       Dpkg::Arch - handle architectures

DESCRIPTION

       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.

FUNCTIONS

       $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.
