<p>A new minor release of <a rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcppredis.html" target="_blank">RcppRedis</a> arrived on <a rel="nofollow" href="http://cran.r-project.org/" target="_blank">CRAN</a> earlier today. <a rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcppredis.html" target="_blank">RcppRedis</a> is one of several packages to connect R to the fabulous <a rel="nofollow" href="https://redis.io/" target="_blank">Redis</a> in-memory datastructure store (and much more). <a rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcppredis.html" target="_blank">RcppRedis</a> does not pretend to be feature complete, but it may do some things faster than the other interfaces, and also offers an optional coupling with <a rel="nofollow" href="https://msgpack.org/index.html" target="_blank">MessagePack</a> binary (de)serialization via <a rel="nofollow" href="https://github.com/eddelbuettel/rcppmsgpack" target="_blank">RcppMsgPack</a>. The package has carried production loads for several years now.</p>
<p>This release adds a few functions for the <em>hash</em> data structure thanks to <a rel="nofollow" href="https://github.com/armstrtw" target="_blank">Whit</a>. I also relented and now embed the small <a rel="nofollow" href="https://github.com/redis/hiredis" target="_blank">hiredis</a> C library as I got tired of seeing builds fail on macOS where the CRAN maintainer was either unwilling or unable to install an external hiredis library. Some packaging details were also brushed up. Fuller details below.</p>
<blockquote>
<h4>Changes in version 0.1.9 (2018-10-27)</h4>
<ul>
<li>
<p>The <code>configure</code> setup is more robust with respect to the C++ setup [CRAN request].</p>
</li>
<li>
<p>The Travis builds was updated to R 3.5 along with all others (<a rel="nofollow" href="https://github.com/eddelbuettel/rcppredis/pull/34" target="_blank">#34</a>).</p>
</li>
<li>
<p>A new Redis function <code>hexists</code> was added (Whit Armstrong in <a rel="nofollow" href="https://github.com/eddelbuettel/rcppredis/pull/35" target="_blank">#35</a>).</p>
</li>
<li>
<p>The <span>hiredis</span> library source is now included, and built on all systems unwilling or unable to provide it (<a rel="nofollow" href="https://github.com/eddelbuettel/rcppredis/pull/36" target="_blank">#36</a>).</p>
</li>
<li>
<p>Added hash functions HDEL, HLEN, HKEYS, and HGETALL (Whit Armstrong in <a rel="nofollow" href="https://github.com/eddelbuettel/rcppredis/pull/38" target="_blank">#38</a>).</p>
</li>
</ul>
