When I'm checking source forum Phalcon then I see that {%- code -%}

I'm search it on the forum and I found some information a useful ,so I wanted to share with you. For example an unordered list:

<ul id="nav" class="menu">
    {% for menu in menus %}
        <li>{{ link_to(menu.url, menu.title|e) }}</li>
    {% endfor %}
</ul>

It will render like that:

<ul id="nav" class="menu">
    <li><a href="/home">Home</a></li>
    <li><a href="/about">About</a></li>
    <li><a href="/news">News</a></li>
    <li><a href="/vita">Vita</a></li>
</ul>

But this:

<ul id="nav" class="menu">
    {%- for menu in menus -%}
        <li>{{- link_to(menu.url, menu.title|e) }}</li>
    {%- endfor -%}
</ul>

It will output like that:

 <ul id="nav" class="menu"><li><a href="/home">Home</a></li><li><a href="/about">About</a></li><li><a href="/news">News</a></li><li><a href="/vita">Vita</a></li></ul>
