Deprecation Notices

As of Twig 1.21, Twig generates deprecation notices when a template uses deprecated features. See Recipes for more information.

Macros

As of Twig 2.0, macros imported in a file are not available in child templates anymore (via an include call for instance). You need to import macros explicitly in each file where you are using them.

Token Parsers

• As of Twig 1.x, the token parser broker sub-system is deprecated. The following class and interface will be removed in 2.0:

  • Twig_TokenParserBrokerInterface
  • Twig_TokenParserBroker
• As of Twig 1.27, \Twig\Parser::getFilename() is deprecated. From a token parser, use $this->parser->getStream()->getSourceContext()->getPath() instead.
• As of Twig 1.27, \Twig\Parser::getEnvironment() is deprecated.

Extensions

• As of Twig 1.x, the ability to remove an extension is deprecated and the \Twig\Environment::removeExtension() method will be removed in 2.0.
• As of Twig 1.23, the \Twig\Extension\ExtensionInterface::initRuntime() method is deprecated. You have two options to avoid the deprecation notice: if you implement this method to store the environment for your custom filters, functions, or tests, use the needs_environment option instead; if you have more complex needs, explicitly implement \Twig\Extension\InitRuntimeInterface (not recommended).
• As of Twig 1.23, the \Twig\Extension\ExtensionInterface::getGlobals() method is deprecated. Implement \Twig\Extension\GlobalsInterface to avoid deprecation notices.
• As of Twig 1.26, the \Twig\Extension\ExtensionInterface::getName() method is deprecated and it is not used internally anymore.

PEAR

PEAR support has been discontinued in Twig 1.15.1, and no PEAR packages are provided anymore. Use Composer instead.

Filters

• As of Twig 1.x, use \Twig\TwigFilter to add a filter. The following classes and interfaces will be removed in 2.0:

  • Twig_FilterInterface
  • Twig_FilterCallableInterface
  • Twig_Filter
  • Twig_Filter_Function
  • Twig_Filter_Method
  • Twig_Filter_Node
• As of Twig 2.x, the Twig_SimpleFilter class is deprecated and will be removed in Twig 3.x (use \Twig\TwigFilter instead). In Twig 2.x, Twig_SimpleFilter is just an alias for \Twig\TwigFilter.

Functions

• As of Twig 1.x, use \Twig\TwigFunction to add a function. The following classes and interfaces will be removed in 2.0:

  • Twig_FunctionInterface
  • Twig_FunctionCallableInterface
  • Twig_Function
  • Twig_Function_Function
  • Twig_Function_Method
  • Twig_Function_Node
• As of Twig 2.x, the Twig_SimpleFunction class is deprecated and will be removed in Twig 3.x (use \Twig\TwigFunction instead). In Twig 2.x, Twig_SimpleFunction is just an alias for \Twig\TwigFunction.

Tests

• As of Twig 1.x, use \Twig\TwigTest to add a test. The following classes and interfaces will be removed in 2.0:

  • Twig_TestInterface
  • Twig_TestCallableInterface
  • Twig_Test
  • Twig_Test_Function
  • Twig_Test_Method
  • Twig_Test_Node
• As of Twig 2.x, the Twig_SimpleTest class is deprecated and will be removed in Twig 3.x (use \Twig\TwigTest instead). In Twig 2.x, Twig_SimpleTest is just an alias for \Twig\TwigTest.
• The sameas and divisibleby tests are deprecated in favor of same as and divisible by respectively.

Tags

• As of Twig 1.x, the raw tag is deprecated. You should use verbatim instead.

Nodes

• As of Twig 1.x, Node::toXml() is deprecated and will be removed in Twig 2.0.
• As of Twig 1.26, Node::$nodes should only contains \Twig\Node\Node instances, storing a null value is deprecated and won't be possible in Twig 2.x.
• As of Twig 1.27, the filename attribute on \Twig\Node\ModuleNode is deprecated. Use getName() instead.
• As of Twig 1.27, the \Twig\Node\Node::getFilename()/\Twig\Node\Node::getLine() methods are deprecated, use \Twig\Node\Node::getTemplateName()/\Twig\Node\Node::getTemplateLine() instead.

Interfaces

• As of Twig 2.x, the following interfaces are deprecated and empty (they will be removed in Twig 3.0):
• Twig_CompilerInterface (use \Twig\Compiler instead)
• Twig_LexerInterface (use \Twig\Lexer instead)
• Twig_NodeInterface (use \Twig\Node\Node instead)
• Twig_ParserInterface (use \Twig\Parser instead)
• \Twig\Loader\ExistsLoaderInterface (merged with \Twig\Loader\LoaderInterface)
• \Twig\Loader\SourceContextLoaderInterface (merged with \Twig\Loader\LoaderInterface)
• Twig_TemplateInterface (use \Twig\Template instead, and use those constants TwigTemplate::ANY_CALL, TwigTemplate::ARRAY_CALL, TwigTemplate::METHOD_CALL)

Compiler

• As of Twig 1.26, the \Twig\Compiler::getFilename() has been deprecated. You should not use it anyway as its values is not reliable.
• As of Twig 1.27, the \Twig\Compiler::addIndentation() has been deprecated. Use \Twig\Compiler::write('') instead.

Loaders

• As of Twig 1.x, Twig_Loader_String is deprecated and will be removed in 2.0. You can render a string via \Twig\Environment::createTemplate().
• As of Twig 1.27, \Twig\Loader\LoaderInterface::getSource() is deprecated. Implement \Twig\Loader\SourceContextLoaderInterface instead and use getSourceContext().

Node Visitors

• Because of the removal of Twig_NodeInterface in 2.0, you need to extend \Twig\NodeVisitor\AbstractNodeVisitor instead of implementing \Twig\NodeVisitor\NodeVisitorInterface directly to make your node visitors compatible with both Twig 1.x and 2.x.

Globals

• As of Twig 2.x, the ability to register a global variable after the runtime or the extensions have been initialized is not possible anymore (but changing the value of an already registered global is possible).
• As of Twig 1.x, using the _self global variable to get access to the current \Twig\Template instance is deprecated; most usages only need the current template name, which will continue to work in Twig 2.0. In Twig 2.0, _self returns the current template name instead of the current \Twig\Template instance. If you are using {{ _self.templateName }}, just replace it with {{ _self }}.

Miscellaneous

• As of Twig 1.x, \Twig\Environment::clearTemplateCache(), \Twig\Environment::writeCacheFile(), \Twig\Environment::clearCacheFiles(), \Twig\Environment::getCacheFilename(), \Twig\Environment::getTemplateClassPrefix(), \Twig\Environment::getLexer(), \Twig\Environment::getParser(), and \Twig\Environment::getCompiler() are deprecated and will be removed in 2.0.
• As of Twig 1.x, \Twig\Template::getEnvironment() and Twig_TemplateInterface::getEnvironment() are deprecated and will be removed in 2.0.
• As of Twig 1.21, setting the environment option autoescape to true is deprecated and will be removed in 2.0. Use "html" instead.
• As of Twig 1.27, \Twig\Error\Error::getTemplateFile() and \Twig\Error\Error::setTemplateFile() are deprecated. Use \Twig\Error\Error::getTemplateName() and \Twig\Error\Error::setTemplateName() instead.
• As of Twig 1.27, \Twig\Template::getSource() is deprecated. Use \Twig\Template::getSourceContext() instead.
• As of Twig 1.27, \Twig\Parser::addHandler() and \Twig\Parser::addNodeVisitor() are deprecated and will be removed in 2.0.
• As of Twig 1.29, some classes are marked as being final via the `@final` annotation. Those classes will be marked as final in 2.0.
