<h2>Overview</h2><div class="docstring">
<div class="discussion">
<p>Implements glob-like pattern matching.
Exact specifications for globbing rules:</p>
<p>&quot;/&quot;</p>
<ul>
<li>act as directory separators</li>
<li>multiple slashes (i.e. &quot;///&quot;) are the same as one slash (&quot;/&quot;)</li>
<li>slashes are stripped at start and end of an expression or path</li>
<li>slashes are not matched by anything but the globstar (&quot;**&quot;)</li>
</ul>
<p>&quot;<em>&quot; ( regexp: /([^/]</em>)/ )</p>
<ul>
<li>matches from 0 to any number of characters</li>
<li>does not match nothing if placed between two slashes (i.e &quot;/*/&quot;)</li>
<li>result is captured in an array</li>
<li>stops at slashes</li>
<li>greedy (matches as much as possible)</li>
</ul>
<p>&quot;*<em>&quot; ( regexp: /(.</em>)/ )</p>
<ul>
<li>matches any number of characters</li>
<li>matches slashes (&quot;/&quot;)</li>
<li>result is captured in an array</li>
<li>does not stop at slashes</li>
<li>greedy (matches as much as possible)</li>
</ul>
<p>&quot;[...]+&quot; ( regexp: itself, ! and ^ at the start are interchangeable )</p>
<ul>
<li>acts like a regexp range</li>
<li>matches any characters, including slashes if specified</li>
<li>matches any number of characters</li>
<li>valid ways to specify a range: [A-z], [a-z], <a href="ascii%20order">9-z</a></li>
<li>! or ^ at the start invert meaning (any character not in range)</li>
<li>result is captured in an array</li>
</ul>
<p>&quot;:name&quot; ( regexp: acts like a named group for /[^/]*/ )</p>
<ul>
<li>acts like * as defined above</li>
<li>result is captured in a hash with &quot;name&quot; as key</li>
<li>name allows alphanumeric characters and underscores</li>
<li>ignored unless placed between two slashes</li>
</ul>
<p>&quot;(name|name2|...)&quot; ( regexp: itself )</p>
<ul>
<li>matches any of (full keywords) name, name2, ...</li>
<li>result is captured in an array</li>
<li>each name may include only these groups of characters:
<ul>
<li>alphanumeric</li>
<li>slashes</li>
<li>underscores</li>
<li>dashes</li>
</ul></li>
