Twig. Overriding already set variable

I've looked for resolving issue, that was asked in this question. https://github.com/fabpot/Twig/issues/1244

But for me, somehow that does not work...

#layout.html.twig
{{ show }}

#base1.html.twig
{% extends 'layout.html.twig' %}
{% set show = 0 %}

#base2.html.twig
{% extends 'base1.html.twig' %}
{% set show = 1 %}

But when i render base2, i see only 0 ... Why it is not 1 ?

Works perfectly for me. I guess it’s a block problem. Maybe your base1's block appears after the base2's one and overrides the value.

The problem would appear with this code for example:

#base2.html.twig
{% extends 'base1.html.twig' %}
{% block content %}
    {% set show = 1 %}
    {{ parent() }}
    {{ show }}
{% endblock %}

You should try this:

#layout.html.twig
{% block content %}
    {% set show = 0 %}
    {{ show }}
{% endblock %}

#base1.html.twig
{% extends 'layout.html.twig' %}
{% block content %}
    {{ parent() }}
    {% set show = 1 %}
    {{ show }}
{% endblock %}

#base2.html.twig
{% extends 'base1.html.twig' %}
{% block content %}
    {{ parent() }}
    {% set show = 2 %}
    {{ show }}
{% endblock %}

Displaying show variable at each step of the inheritance process, should help you to see what’s going wrong. The final response should display 0 1 2.
