|
||
<p>A regex set corresponds to the union of two or more regular expressions.
|
||
That is, a regex set will match text where at least one of its
|
||
constituent regular expressions matches. A regex set as its formulated here
|
||
provides a touch more power: it will also report <em>which</em> regular
|
||
expressions in the set match. Indeed, this is the key difference between
|
||
regex sets and a single <code>Regex</code> with many alternates, since only one
|
||
alternate can match at a time.</p>
|
||
<p>For example, consider regular expressions to match email addresses and
|
||
domains: <code>[a-z]+@[a-z]+\.(com|org|net)</code> and <code>[a-z]+\.(com|org|net)</code>. If a
|
||
regex set is constructed from those regexes, then searching the text
|
||
<code>foo@example.com</code> will report both regexes as matching. Of course, one
|
||
could accomplish this by compiling each regex on its own and doing two
|
||
searches over the text. The key advantage of using a regex set is that it
|
||
will report the matching regexes using a <em>single pass through the text</em>.
|
||
If one has hundreds or thousands of regexes to match repeatedly (like a URL
|
||
router for a complex web application or a user agent matcher), then a regex
|
||
set can realize huge performance gains.</p>
|
||
<h1 id="example" class="section-header"><a href="#example">Example</a></h1>
|
||
<p>This shows how the above two regexes (for matching email addresses and
|
||
domains) might work:</p>

|
||
<p>After a match, one could then inspect the capture groups to figure out
|
||
which alternates matched. The problem is that it is hard to make this
|
||
approach scale when there are many regexes since the overlap between each
|
||
alternate isn't always obvious to reason about.</p>
|
||
<h1 id="limitations" class="section-header"><a href="#limitations">Limitations</a></h1>
|
||
<p>Regex sets are limited to answering the following two questions:</p>
|
||
<ol>
|
||
<li>Does any regex in the set match?</li>
|
||
<li>If so, which regexes in the set match?</li>
|
||
</ol>
|
||
<p>As with the main <code>Regex</code> type, it is cheaper to ask (1) instead of (2)
|
||
since the matching engines can stop after the first match is found.</p>
|
||
<p>Other features like finding the location of successive matches or their
|
||
sub-captures aren't supported. If you need this functionality, the
|
||
recommended approach is to compile each regex in the set independently and
|
||
selectively match them based on which regexes in the set matched.</p>
|
||
<h1 id="performance" class="section-header"><a href="#performance">Performance</a></h1>
|
||
<p>A <code>RegexSet</code> has the same performance characteristics as <code>Regex</code>. Namely,
|
||
search takes <code>O(mn)</code> time, where <code>m</code> is proportional to the size of the
|
||
regex set and <code>n</code> is proportional to the length of the search text.</p>
