How do you concatenate 'some text with a' `stringOrVariable`? – Pathros Mar 02 '16 at 16:00

In PHP we use dot `.` to concatenate strings or variables, in Twig we use `~`. Example: `{{ "Hello" ~ a }}` to concatenate a string and a variable. For variables you can do `{{ a ~ b ~ c }}` The `~` replaces the dot `.` – Anthony Dec 08 '16 at 07:00

Use the "~" operator. This will concatenate your two strings. The "+" operator cannot be used to combine strings.

You would get this:

{% set c=a~b %}

More info: The "+" operator: Adds two objects together (the operands are casted to numbers).

A clearer example for the {% block page %}...{% endblock %}:

{% block page %}
    {% set page = page | merge({
    "title"       : branchName,
    "description" : "This description has "~branchName~" as its title"
    }) %}
    {{ parent() }}
{% endblock %}

A clearer example for the {% block content %}...{% endblock %}:

{% block content %}
    This is just a sample string for {{ branchName }} that needs no concatenation
{% endblock %}
