Twig (template engine)

• Complex control flow
• Automatic escaping
• Template inheritance
• Variable filters{{Cite web|url=https://twig.symfony.com/doc/3.x/filters/index.html|title=Filters - Documentation - Twig - The flexible, fast, and secure PHP template engine|website=Twig}}
• i18n support (gettext)
• Macros
• Fully extendable{{Cite web|url=https://twig.symfony.com/doc/3.x/advanced.html|title=Extending Twig - Documentation - Twig - The flexible, fast, and secure PHP template engine|website=Twig}}

Twig is supported by the following integrated development environments:

• Eclipse via the Twig plugin
• Komodo and Komodo Edit via the Twig highlight/syntax check mode
• NetBeans via the Twig syntax plugin (until 7.1, native as of 7.2)
• PhpStorm (native as of 2.1)
• IntelliJ IDEs, including WebStorm, via a plugin

And the text editors:

• Atom via the PHP-twig for atom
• Emacs via web-mode.el
• Notepad++ via the Notepad++ Twig Highlighter
• Sublime Text via the Twig bundle
• TextMate via the Twig bundle
• Vim via the Jinja syntax plugin or the vim-twig plugin
• Brackets via Brackets Twig
• Visual Studio Code via the Twig extension
• GTKSourceView via the Twig language definition
• Coda via the Twig syntax mode
• Coda 2 via the other Twig syntax mode
• SubEthaEdit via the Twig syntax mode

Twig defines three kinds of delimiters:

• {{ ... }}, to print the content of variables or the result of evaluating an expression (e.g.: an inherited Twig template with {{ parent() }}).
• {# ... #}, to add comments in the templates. These comments aren't included in the rendered page.
• {% ... %}, to execute statements, such as for-loops.
• {% set foo = 'bar' %}, to assign.{{Cite web|url=https://twig.symfony.com/doc/2.x/tags/set.html|title=set - Documentation - Twig - The flexible, fast, and secure PHP template engine|website=Twig}}
• {% if i is defined and i == 1%} ... {% endif %}: condition.
• {% for i in 0..10 %} ... {% endfor %}: counter in a loop.

The apostrophe (') is the escape character.

To create an iterative array:

{% set myArray = [1, 2] %}

An associative array:

{% set myArray = {'key': 'value'} %}

The operators precedence is, from the less to more priority:

The filters provide some treatments on an expression, when placed after it, separated by pipes. For example:

• capitalize: changes a string's first letter to capital.
• upper: changes a whole string to capital.
• first: displays the first line of an array.
• length: returns a variable size.

• loop contains the current loop information. For example loop.index corresponds to the number of iterations which have already occurred.
• The global variables begin with underscores. For example:
• _route (URL part located after the domain)
• _self (current file name)
• :So, to the a page route: {{ path(app.request.attributes.get('_route'), app.request.attributes.get('_route_params')) }}
• The CGI environment variables, such as {{ app.request.server.get('SERVER_NAME') }}.

The example below demonstrates some basic features of Twig.

{% extends "base.html" %}

{% block navigation %}

{% for item in navigation %}

• {% if item.level == 2 %}  {% endif %}

  {{ item.caption|upper }}

{% endfor %}

{% endblock navigation %}
