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, %options)

Validate an architecture name.

If the "positive" option is 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, %options)

Parse an architecture list.

If the "positive" option is set to a true value, only positive architectures will be accepted, otherwise negated architectures are allowed.
