Changelog History

• v4.2.0 Changes

  January 12, 2019

  ➕ Added

  • 🏗 [PHP 7.4] Add support for typed properties through a new type subnode of Stmt\Property. Additionally Builder\Property now has a setType() method. (#567)
  • ➕ Add kind attribute to Cast\Double_, which allows to distinguish between (float), (double) and (real). The form of the cast will be preserved by the pretty printer. (#565)

  🛠 Fixed

  • ✂ Remove assertion when pretty printing anonymous class with a name (#554).

• v4.1.1 Changes

  December 26, 2018

  🛠 Fixed

  • 🛠 Fix "undefined offset" notice when parsing specific malformed code (#551).

  ➕ Added

  • 👌 Support error recovery for missing return type (function foo() : {}) (#544).

• v4.1.0 Changes

  October 10, 2018

  ➕ Added

  • ➕ Added support for PHP 7.3 flexible heredoc/nowdoc strings, completing support for PHP 7.3. There are two caveats for this feature:
    • In some rare, pathological cases flexible heredoc/nowdoc strings change the interpretation of existing doc strings. PHP-Parser will now use the new interpretation.
    • Flexible heredoc/nowdoc strings require special support from the lexer. Because this is not available on PHP versions before 7.3, support has to be emulated. This emulation is not perfect and some cases which we do not expect to occur in practice (such as flexible doc strings being nested within each other through abuse of variable-variable interpolation syntax) may not be recognized correctly.
  • Added DONT_TRAVERSE_CURRENT_AND_CHILDREN to NodeTraverser to skip both traversal of child nodes, and prevent subsequent visitors from visiting the current node.

• v4.0.4 Changes

  September 18, 2018

  ➕ Added

  • 🏗 The following methods have been added to BuilderFactory:
    • useTrait() (fluent builder)
    • traitUseAdaptation() (fluent builder)
    • useFunction() (fluent builder)
    • useConst() (fluent builder)
    • var()
    • propertyFetch()

  🗄 Deprecated

  • 🏗 Builder\Param::setTypeHint() has been deprecated in favor of the newly introduced Builder\Param::setType().

• v4.0.3 Changes

  July 15, 2018

  🛠 Fixed

  • 🛠 Fixed possible undefined offset notice in formatting-preserving printer. (#513)

  ➕ Added

  • 👌 Improved error recovery inside arrays.
  • Preserve trailing comment inside classes. Note: This change is possibly BC breaking if your code validates that classes can only contain certain statement types. After this change, classes can also contain Nop statements, while this was not previously possible. (#509)

• v4.0.2 Changes

  June 03, 2018

  ➕ Added

  • 👌 Improved error recovery inside classes.
  • 👌 Support error recovery for foreach without as.
  • 👌 Support error recovery for parameters without variable (function (Type ) {}).
  • 👌 Support error recovery for functions without body (function ($foo)).

• v4.0.1 Changes

  March 25, 2018

  ➕ Added

  • 👍 [PHP 7.3] Added support for trailing commas in function calls.
  • 👍 [PHP 7.3] Added support for by-reference array destructuring.
  • ➕ Added checks to node traverser to prevent replacing a statement with an expression or vice versa. This should prevent common mistakes in the implementation of node visitors.
  • ➕ Added the following methods to BuilderFactory, to simplify creation of expressions:
    • funcCall()
    • methodCall()
    • staticCall()
    • new()
    • constFetch()
    • classConstFetch()

• v4.0.0 Changes

  February 28, 2018

  📚 This is a new major version of the PHP-Parser library. The biggest new feature in this release is an experimental pretty-printing mode, which preserves formatting for parts of the code which have not been modified. As such, it should now be much easier to use PHP-Parser for automated code refactorings. See the pretty printer documentation for information on how to use this functionality

  ⬆️ The following changelog lists all significant changes relative to PHP-Parser 3.1. For more information on backwards incompatible changes, please see the upgrading guide.

  ➕ Added

  • ➕ Added experimental support for format-preserving pretty-printing. In this mode formatting will be preserved for parts of the code which have not been modified.
  • ➕ Added replaceNodes option to NameResolver, defaulting to true. If this option is disabled, resolved names will be added as resolvedName attributes, instead of replacing the original names.
  • ➕ Added NodeFinder class, which can be used to find nodes based on a callback or class name. This is a utility to avoid custom node visitor implementations for simple search operations.
  • ➕ Added ClassMethod::isMagic() method.
  • ➕ Added BuilderFactory methods: val() method for creating an AST for a simple value, concat() for creating concatenation trees, args() for preparing function arguments.
  • ➕ Added NameContext class, which encapsulates the NameResolver logic independently of the actual AST traversal. This facilitates use in other context, such as class names in doc comments. Additionally it provides an API for getting the shortest representation of a name.
  • ➕ Added Node::setAttributes() method.
  • ➕ Added JsonDecoder. This allows conversion JSON back into an AST.
  • ➕ Added Name methods toLowerString() and isSpecialClassName().
  • ➕ Added Identifier and VarLikeIdentifier nodes, which are used in place of simple strings in many places.
  • ➕ Added getComments(), getStartLine(), getEndLine(), getStartTokenPos(), getEndTokenPos(), getStartFilePos() and getEndFilePos() methods to Node. These provide a more obvious access point for the already existing attributes of the same name.
  • ➕ Added ConstExprEvaluator to evaluate constant expressions to PHP values.
  • ➕ Added Expr\BinaryOp::getOperatorSigil(), returning + for Expr\BinaryOp\Plus, etc.
  • ➕ Added start token offsets to comments.

  🔄 Changed

  • ⬆️ Many subnodes that previously held simple strings now use Identifier (or VarLikeIdentifier) nodes. Please see the UPGRADE-4.0 file for an exhaustive list of affected nodes and some notes on possible impact.
  • Expression statements (expr;) are now represented using a Stmt\Expression node. Previously these statements were directly represented as their constituent expression.
  • The name subnode of Param has been renamed to var and now contains a Variable rather than a plain string.
  • The name subnode of StaticVar has been renamed to var and now contains a Variable rather than a plain string.
  • The var subnode of ClosureUse now contains a Variable rather than a plain string.
  • The var subnode of Catch now contains a Variable rather than a plain string.
  • The alias subnode of UseUse is now null if no explicit alias is given. As such, use Foo\Bar and use Foo\Bar as Bar are now represented differently. The getAlias() method can be used to get the effective alias, even if it is not explicitly given.

  ✂ Removed

  • 👌 Support for running on PHP 5 and HHVM has been removed. You can however still parse code of old PHP versions (such as PHP 5.2), while running on PHP 7.
  • ✂ Removed type subnode on Class, ClassMethod and Property nodes. Use flags instead.
  • 🚚 The ClassConst::isStatic() method has been removed. Constants cannot have a static modifier.
  • 🚚 The NodeTraverser no longer accepts false as a return value from a leaveNode() method. NodeTraverser::REMOVE_NODE should be returned instead.
  • 🚚 The Node::setLine() method has been removed. If you really need to, you can use setAttribute() instead.
  • The misspelled Class_::VISIBILITY_MODIFER_MASK constant has been dropped in favor of Class_::VISIBILITY_MODIFIER_MASK.
  • 🚚 The XML serializer has been removed. As such, the classes Serializer\XML, and Unserializer\XML, as well as the interfaces Serializer and Unserializer no longer exist.
  • 🏗 The BuilderAbstract class has been removed. It's functionality is moved into BuilderHelpers. However, this is an internal class and should not be used directly.
  • 🚚 The Autoloader class has been removed. It is now required to use the Composer autoloader.
