<div id="content"><div id="content-area"><div id="article-title">spath</div><div id="article"><a href="https://github.com/svetlyak40wt/cl-spath">SPath</a> is a library for running search queries against s-expressions, intended to match parts of them that the user needs. It is inspired by <a href="http://web.archive.org/web/20160304045626/http://www.defmacro.org/ramblings/s-query.html">s-query</a>, the syntax of LOOP, and loosely by XPath; not that it has the full expressive power of XPath, but some of the stylistic choices and ideas were taken from there. In particular, SPath finds all instances of a match in the same sort of way as <a href="XPath.html" class="internal">XPath</a>.<p>In other words, it's a DSL for pulling bits out of lists.<p>The goal of SPath, like s-query, was to provide a means to easily dig around in <a href="XML.html" class="internal">XML</a> structures when represented as s-expressions, but unlike s-query I tried to do it in a fashion agnostic to the XML generation system in question. I also consider it of general utility, because I get sick of writing nests of list operations.<p>It was created by <a href="http://web.archive.org/web/20210212085735/http://digitalkingdom.org/~rlpowell/">Robin Lee Powell</a>, and is in the <a href="public domain.html" class="category">public domain</a>.<p>SPath requires <a href="Heresy.html" class="internal">Heresy</a>.<p>Documentation, such as it is, can be found at <a href="https://github.com/svetlyak40wt/cl-spath/blob/master/README">the SPath readme</a>. The <a href="https://github.com/svetlyak40wt/cl-spath/blob/master/tests.lisp">SPath test suite</a> should also effectively document everything SPath can do, albeit not in a very readable fashion.<p><hr>
