NAME¶

Lintian::Data::Architectures -- Lintian API for handling architectures and wildcards

SYNOPSIS¶

 use Lintian::Data::Architectures;

DESCRIPTION¶

Lintian API for checking and expanding architectures and architecture wildcards. The functions are backed by a data file, so it may be out of date (use private/refresh-archs to update it).

Generally all architecture names are in the format "$os-$architecture" and wildcards are "$os-any" or "any-$cpu", though there are exceptions:

Note that the architecture and cpu name are not always identical (example architecture "armhf" has cpu name "arm").

INSTANCE METHODS¶

"wildcards"

"names"

is_wildcard ($wildcard)

Returns a truth value if $wildcard is a known architecture wildcard.

Note: 'any' is considered a wildcard and not an architecture.

is_release_architecture ($architecture)

Returns a truth value if $architecture is (an alias of) a Debian machine architecture. It returns a false value for architecture wildcards (including "any") and unknown architectures.

expand_wildcard ($wildcard)

Returns a list of architectures that this wildcard expands to. No order is guaranteed (even between calls). Returned values must not be modified.

Note: This list is based on the architectures in Lintian's data file. However, many of these are not supported or used in Debian or any of its derivatives.

The returned values matches the list generated by dpkg-architecture -L, so the returned list may use (e.g.) "amd64" for "linux-amd64".

wildcard_includes ($wildcard, $architecture)

Returns a truth value if $architecture is included in the list of architectures that $wildcard expands to.

This is generally faster than

  grep { $_ eq $architecture } expand_arch_wildcard ($wildcard)
    

It also properly handles cases like "linux-amd64" and "amd64" being aliases.
