# [NAME](#NAME)

Dpkg::Arch - handle architectures

# [DESCRIPTION](#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](#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.

$bool = debarch\_is\_invalid($arch, %opts)

Validate an architecture name.

Options:

[**positive**](#positive)

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

$bool = debarch\_is\_illegal($arch, %opts)

This is a deprecated alias for debarch\_is\_invalid.

$bool = debarch\_is\_concerned($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**](#positive~2)

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