<p>Lintian::Architecture -- Lintian API for handling architectures and wildcards</p>
<h1><a class='u' href='#___top' title='click to go to top of document'

>SYNOPSIS</a></h1>
<pre> use Lintian::Architecture qw(:all);
print "arch\n" if is_arch ('i386');
print "wildcard\n" if is_arch_wildcard ('any');

<h1><a class='u' href='#___top' title='click to go to top of document'
name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p>Lintian API for checking and expanding architectures and architecture wildcards. The functions are backed by a <a href="../Lintian/Data.html" class="podlinkpod"
>data</a> file, so it may be out of date (use private/refresh-archs to update it).</p>
<p>Generally all architecture names are in the format "$os-$arch" and wildcards are "$os-any" or "any-$cpu", though there are exceptions:</p>
<ul>
<li>"all" is the "architecture independent" architecture.
<p>Source: Policy §5.6.8 (v3.9.3)</p>
</li>
<li>"any" is a wildcard matching any architecture except "all".
<p>Source: Policy §5.6.8 (v3.9.3)</p>
</li>
<li>All other cases of "$arch" are short for "linux-$arch"
<p>Source: Policy §11.1 (v3.9.3)</p>
</li>
</ul>
<p>Note that the architecture and cpu name are not always identical (example architecture "armhf" has cpu name "arm").</p>
<h1><a class='u' href='#___top' title='click to go to top of document'
name="FUNCTIONS"
>FUNCTIONS</a></h1>
<p>The following methods are exportable:</p>
<dl>
<dt><a name="is_arch_wildcard_($wc)"
>is_arch_wildcard ($wc)</a></dt>
<dd>
<p>Returns a truth value if $wc is a known architecture wildcard.</p>
<p>Note: 'any' is considered a wildcard and not an architecture.</p>
<dt><a name="is_arch_($arch)"
>is_arch ($arch)</a></dt>
<dd>
<p>Returns a truth value if $arch is (an alias of) a Debian machine architecture OR the special value "all". It returns a false value for architecture wildcards (including "any") and unknown architectures.</p>
<dt><a name="is_arch_or_wildcard_($arch)"
>is_arch_or_wildcard ($arch)</a></dt>
<dd>
<p>Returns a truth value if $arch is either an architecture or an architecture wildcard.</p>
<p>Shorthand for:</p>
<pre> is_arch ($arch) || is_arch_wildcard ($arch)</pre>
<dt><a name="expand_arch_wildcard_($wc)"
>expand_arch_wildcard ($wc)</a></dt>
<dd>
<p>Returns a list of architectures that this wildcard expands to. No order is guaranteed (even between calls). Returned values must not be modified.</p>
<p>Note: This list is based on the architectures in Lintian's data file. However, many of these are not supported or used in Debian or any of its derivatives.</p>
<p>The returned values matches the list generated by dpkg-architecture -L, so the returned list may use (e.g.) "amd64" for "linux-amd64".</p>
<dt><a name="wildcard_includes_arch_($wc,_$arch)"
>wildcard_includes_arch ($wc, $arch)</a></dt>
<dd>
<p>Returns a truth value if $arch is included in the list of architectures that $wc expands to.</p>
<p>This is generally faster than</p>
<pre> grep { $_ eq $arch } expand_arch_wildcard ($wc)</pre>
<p>It also properly handles cases like "linux-amd64" and "amd64" being aliases.</p>
