<h1>Generating dot graphs<a class="headerlink" href="#generating-dot-graphs" title="Permalink to this headline">ΒΆ</a></h1>
<p>In larger workspaces it’s often hard to understand the dependency structure. With bake you can generate a dot file (see <a class="reference external" href="http://www.graphviz.org">http://www.graphviz.org</a>):</p>
<div class="highlight-console"><div class="highlight"><pre><span class="go">bake ... --dot <dot filename></span>
</pre></div>
</div>
<p>The dot file is a text file with all dependencies included. It is easy to render an image, e.g. with</p>
<div class="highlight-console"><div class="highlight"><pre><span class="go">tred <dot filename> | dot -Tpng -o <png image filename></span>
</pre></div>
</div>
<img alt="../_images/dot.png" src="../_images/dot.png" />
<ul class="simple">
<li>Projects are rectangles</li>
<li>Configs are ellipses</li>
<li>CustomConfigs are red</li>
<li>ExecutableConfigs are green</li>
<li>LibraryConfigs are cyan</li>
</ul>
<p>It’s possible to generate only a part of the whole graph with -p (same as for building only a part of the code). e.g.:</p>
<div class="highlight-console"><div class="highlight"><pre><span class="go">bake ... --dot <dot filename> -p lib2</span>
<span class="go">bake ... --dot <dot filename> -p lib2,testa</span>
</pre></div>
</div>
<p>Which results in:</p>
<img alt="../_images/dotP.png" src="../_images/dotP.png" />
<img alt="../_images/dotPC.png" src="../_images/dotPC.png" />
