Overview</h1></div></div></div><p>Now that you know how to get started, let’s take a look at
what Erlang.mk can do for you.</p><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_building_your_project"></a>3.1. Building your project</h2></div></div></div><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><p>Erlang.mk will happily build all <a class="link" href="building.html" title="Chapter 6. Building">Erlang-specific files</a>
<a class="xref" href="building.html" title="Chapter 6. Building">Chapter 6, <em>Building</em></a>
you throw at it. Other kinds of files too, like C or C++ code
when you are working on <a class="link" href="ports.html" title="Chapter 8. NIFs and port drivers">a NIF or a port driver</a>
<a class="xref" href="ports.html" title="Chapter 8. NIFs and port drivers">Chapter 8, <em>NIFs and port drivers</em></a>.</p><p>Erlang.mk embraces the concept of <a class="link" href="deps.html" title="Chapter 7. Packages and dependencies">source dependencies</a>
<a class="xref" href="deps.html" title="Chapter 7. Packages and dependencies">Chapter 7, <em>Packages and dependencies</em></a>.
It can fetch dependency source code using a variety of mechanisms,
including fetching from Git, Mercurial or SVN.</p><p>Erlang.mk will automatically <a class="link" href="relx.html" title="Chapter 9. Releases">generate releases</a>
<a class="xref" href="relx.html" title="Chapter 9. Releases">Chapter 9, <em>Releases</em></a>
when applicable. It can also <a class="link" href="escript.html" title="Chapter 11. Escripts">generate escripts</a>
<a class="xref" href="escript.html" title="Chapter 11. Escripts">Chapter 11, <em>Escripts</em></a>.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_exploring_the_package_index"></a>3.2. Exploring the package index</h2></div></div></div><p>Erlang.mk comes with a <a class="link" href="deps.html" title="Chapter 7. Packages and dependencies">built-in package index</a>
<a class="xref" href="deps.html" title="Chapter 7. Packages and dependencies">Chapter 7, <em>Packages and dependencies</em></a>.
It is built as an extension of the dependency system and is
meant to be used for discovery purposes.</p><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><p>You can get a list of all packages known to Erlang.mk by using
the <code class="literal">search</code> target:</p><pre class="programlisting">$ make search</pre><p>You can also use this target to search across all packages, for
example to find all packages related to Cowboy:</p><pre class="programlisting">$ make search q=cowboy</pre></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_generating_documentation"></a>3.3.

EDoc comments">EDoc</a>
<a class="xref" href="edoc.html" title="Chapter 15. EDoc comments">Chapter 15, <em>EDoc comments</em></a> generates HTML documentation directly from
your source code.</p><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’s where <span class="emphasis"><em>Asciidoc</em></span> comes in.</p><p>The <a class="link" href="asciidoc.html" title="Chapter 14. AsciiDoc documentation">Asciidoc</a>
<a class="xref" href="asciidoc.html" title="Chapter 14. AsciiDoc documentation">Chapter 14, <em>AsciiDoc documentation</em></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 <span class="emphasis"><em>doc/src/</em></span> folder in
your repository.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_running_tests"></a>3.4. Running tests</h2></div></div></div><p>Erlang.mk supports a lot of different testing and static
analysis tools.</p><p>The <a class="link" href="shell.html" title="Chapter 17. Erlang shell">make shell</a>
<a class="xref" href="shell.html" title="Chapter 17. Erlang shell">Chapter 17, <em>Erlang shell</em></a> command allows you
to test your project manually. You can automate these
unit tests with <a class="link" href="eunit.html" title="Chapter 18. EUnit">EUnit</a>

setting up and using <a class="link" href="ci.html" title="Chapter 21. Continuous integration">Continuous integration</a>
<a class="xref" href="ci.html" title="Chapter 21. Continuous integration">Chapter 21, <em>Continuous integration</em></a>.</p><p>On the static analysis side of things, Erlang.mk comes with
support for <a class="link" href="dialyzer.html" title="Chapter 22. Dialyzer">Dialyzer</a>
