                <h1><a href="">LessCSS Support</a></h1>

<p>If you use <a href="http://lesscss.org/">LessCSS</a> to stay sane while writing CSS, you probably know it
can be a pain to run <code>lessc --watch static/style.less</code> every time you want to
work on your styles. It gets even worse when you have more than one <code>.less</code>
file.</p>
<p>Garter provides a function that will automatically re-render <code>.less</code> files
into CSS before each request if they've changed.</p>
<p><strong>NOTE:</strong> You need to have the LessCSS gem installed for this to work.</p>
<p>You can activate it by calling the <code>lesscss</code> function with your Flask app as a
parameter:</p>
<div class="codehilite"><pre><span class="kn">from</span> <span class="nn">garter.lesscss</span> <span class="kn">import</span> <span class="n">lesscss</span>
<span class="n">lesscss</span><span class="p">(</span><span class="n">app</span><span class="p">)</span>
</pre></div>


<p>This will watch your app's static media directory and automatically render
<code>.less</code> files into <code>.css</code> files in the same (sub)directory.</p>
<p>When you deploy your app you might not want to accept the overhead of checking
the modification time of your <code>.less</code> and <code>.css</code> files on each request. A
simple way to avoid this is wrapping the <code>lesscss</code> call in an <code>if</code> statement:</p>
<div class="codehilite"><pre><span class="k">if</span> <span class="n">app</span><span class="o">.</span><span class="n">debug</span><span class="p">:</span>
    <span class="kn">from</span> <span class="nn">garter.lesscss</span> <span class="kn">import</span> <span class="n">lesscss</span>
    <span class="n">lesscss</span><span class="p">(</span><span class="n">app</span><span class="p">)</span>
</pre></div>


<p>If you do this <em>you'll</em> be responsible for rendering the <code>.less</code> files into
CSS when you deploy in non-debug mode to your production server.</p>
