<h1 class="lined-header"><span>Overview</span></h1>

<div class="paragraph"><p>Now that you know how to get started, let&#8217;s take a look at
what Erlang.mk can do for you.</p></div>
<div class="sect1">
<h2 id="_building_your_project">Building your project</h2>
<div class="sectionbody">
<div class="paragraph"><p>Erlang.mk is first and foremost a build tool. It is especially
tailored for Erlang developers and follows widely accepted
practices in the Erlang community.</p></div>
<div class="paragraph"><p>Erlang.mk will happily build all <a href="../building">Erlang-specific files</a>
you throw at it. Other kinds of files too, like C or C++ code
when you are working on <a href="../ports">a NIF or a port driver</a>.</p></div>
<div class="paragraph"><p>Erlang.mk embraces the concept of <a href="../deps">source dependencies</a>.
It can fetch dependency source code using a variety of mechanisms,
including fetching from Git, Mercurial or SVN.</p></div>
<div class="paragraph"><p>Erlang.mk will automatically <a href="../relx">generate releases</a>
when applicable. It can also <a href="../escript">generate escripts</a>.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_exploring_the_package_index">Exploring the package index</h2>
<div class="sectionbody">
<div class="paragraph"><p>Erlang.mk comes with a <a href="../deps">built-in package index</a>.
It is built as an extension of the dependency system and is
meant to be used for discovery purposes.</p></div>
<div class="paragraph"><p>No package is ever installed, they are only used as dependencies
and are always project-specific. They can be thought of as a
shortcut over plain dependencies.</p></div>
<div class="paragraph"><p>You can get a list of all packages known to Erlang.mk by using
the <code>search</code> target:</p></div>

<pre><tt>$ make search</tt></pre></div></div>
<div class="paragraph"><p>You can also use this target to search across all packages, for
example to find all packages related to Cowboy:</p></div>

</div>
<div class="sect1">
<h2 id="_generating_documentation">Generating documentation</h2>
<div class="sectionbody">
<div class="paragraph"><p>Erlang.mk supports <em>EDoc</em> and <em>Asciidoc</em>.</p></div>
<div class="paragraph"><p><a href="../edoc">EDoc</a> generates HTML documentation directly from
your source code.</p></div>
<div class="paragraph"><p>While it is convenient, ask yourself: if all the documentation is
inside the source code, why not just open the source code directly?
That&#8217;s where <em>Asciidoc</em> comes in.</p></div>
<div class="paragraph"><p>The <a href="../asciidoc">Asciidoc</a> plugin expects all documentation
to be separate from source. It will generate HTML, PDF, man pages and
more from the documentation you write in the <em>doc/src/</em> folder in
your repository.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_running_tests">Running tests</h2>
<div class="sectionbody">
<div class="paragraph"><p>Erlang.mk supports a lot of different testing and static
analysis tools.</p></div>
<div class="paragraph"><p>The <a href="../shell">make shell</a> command allows you
to test your project manually. You can automate these
unit tests with <a href="../eunit">EUnit</a> and test
your entire system with <a href="../ct">Common Test</a>.
<a href="../coverage">Code coverage</a> can of course
be enabled during tests.</p></div>
<div class="paragraph"><p>Erlang.mk comes with features to make your life easier when
setting up and using <a href="../ci">Continuous integration</a>.</p></div>
<div class="paragraph"><p>On the static analysis side of things, Erlang.mk comes with
support for <a href="../dialyzer">Dialyzer</a> and <a href="#xref">Xref</a>,
to perform success typing analysis and cross referencing
of the code.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_need_more">Need more?</h2>
<div class="sectionbody">
<div class="paragraph"><p>Not convinced yet? You can read about <a href="../why">why you should use Erlang.mk</a>
and its <a href="../history">history</a>. And if you&#8217;re still not
convinced after that, it&#8217;s OK! The world would be boring if
everyone agreed on everything all the time.</p></div>
