very nice. one thing i&#x27;m missing tho is a callback functionality.<p>for example i did a quick scraper for tesco.com<p><pre><code>  {
    page(url:&quot;http:&#x2F;&#x2F;www.tesco.com&#x2F;groceries&#x2F;product&#x2F;browse&#x2F;default.aspx?N=4294793330&amp;Ne=4294793660&quot;) {
      items: query(selector:&quot;li.product&quot;) {
        title: text(selector:&quot;span[data-title=true]&quot;)
        price: text(selector:&quot;span.linePrice&quot;)
        url: attr(selector:&quot;a:eq(0)&quot;, name:&quot;href&quot;)
      }
    }
  }
</code></pre>
now the url field on the page is relative. it would be nice to have a callback param where i could execute a function on the result and prefix the url with &quot;<a href="http:&#x2F;&#x2F;www.tesco.com&quot;" rel="nofollow">http:&#x2F;&#x2F;www.tesco.com&quot;</a><p>trying to make a pull request now
