Is it possible to use the block tag of Swig in Assemble?

Using assemble-swig, here is my template:

<!doctype html><html lang="it">

<head>
{% include "src/templates/partials/html_header.swig" %}
</head>
<body>
{% include "src/templates/partials/body_header.swig" %}

<header class="articleHeader intro"><div class="inner">
{% block articleheader %}{% endblock %}
</div></header>

<div class="body"><div class="inner">

<article class="main{% if nosidebar %} noSideBarArticle{% endif %}">

{% block content %}{% endblock %}

</article>

{% block sidebar %}{% endblock %}
</div></div>

{% include "src/templates/partials/body_footer.swig" %}
{% block javascript %}{% endblock %}
 </body>
</html>

Here is my page:

---
title: "test"
---

{% block articleheader %}

<h1>Article Header!</h1>

{% endblock %}

{% block content %}

<p>this is the content!</p>

{% endblock %}

The result: No data from the page is show

(content of html_header and body_header goes here...)

<header class="articleHeader intro"><div class="inner">

</div></header>


<div class="body"><div class="inner">

<article class="main">

</article>

(content of html_header and body_footer goes here...)

Only if I use the tag {{body}} in the template all the content of the page is inserted but with no respect for the block tag.

Solution

Yes, it seems to be possible if you don't use the layout of Assemble.

I get it to work setting the layout property to false in the config:

assemble: {
  options: {
    engine: 'swig',
    ...
    layout: false,
    ...

and then in each file adding:

 {% extends 'src/layouts/default.swig' %}

at the top of the content.
