CAF: C++ Actor Framework

I was bored so I added CAF to pkgsrc, which you can use to install CAF on NetBSD&#x2F;Linux&#x2F;macOS and a variety of other Unix-ey platforms that pkgsrc supports:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;NetBSD&#x2F;pkgsrc-wip&#x2F;tree&#x2F;master&#x2F;actor-framework" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;NetBSD&#x2F;pkgsrc-wip&#x2F;tree&#x2F;master&#x2F;actor-frame...</a><p><pre><code> git clone https:&#x2F;&#x2F;github.com&#x2F;NetBSD&#x2F;pkgsrc --depth 1 ~&#x2F;pkgsrc git clone https:&#x2F;&#x2F;github.com&#x2F;NetBSD&#x2F;pkgsrc-wip --depth 1 ~&#x2F;pkgsrc&#x2F;wip cd ~&#x2F;pkgsrc&#x2F;bootstrap .&#x2F;bootstrap --unprivileged cd ~&#x2F;pkgsrc&#x2F;wip&#x2F;actor-model ~&#x2F;pkg&#x2F;bin&#x2F;bmake install ~&#x2F;pkg&#x2F;sbin&#x2F;pkg_info -L actor-model </code></pre> That is all.

&gt; Decoupling concurrently running software components via message passing avoids race conditions by design.<p>How am I supposed to read this? It&#x27;s obviously not &quot;message passing eliminates race conditions&quot;, so perhaps it&#x27;s intended to say something like &quot;you need to design the components to avoid race conditions.&quot;

Honestly, the source code of the examples looks rather complicated, like something that should better be generated from a nicer high-level language that has a native actor concept. (Obviously, the power of C++ templates does not come for free - you pay with noisy code and increased cognitive load.)

In the Docs:Overview [0], the compile and build instructions are not showing up for some reason.<p>[0] <a href="https:&#x2F;&#x2F;actor-framework.readthedocs.io&#x2F;en&#x2F;latest&#x2F;Overview.html" rel="nofollow">https:&#x2F;&#x2F;actor-framework.readthedocs.io&#x2F;en&#x2F;latest&#x2F;Overview.ht...</a>

&quot;Actor&quot; architecture is supposed to enable high developer productivity but it&#x27;s been a decade since the article so I wonder how it&#x27;s working out? The most prominent project of which I am aware is FoundationDB.

If someone&#x27;s got a nice actor library written in and for C, I&#x27;m all hears.

The activity around C++20 has gotten to the point where I’m skeptical of great libraries like this because I don’t want to learn something third-party when I might be able to use STL equivalents in just a few hundred days.
