Version 1.2.2-dev

Nothing yet.

Version 1.2.1 (2015-03-24)

  • Fixed registration of the aliases introduced in 1.2.0. Previously the old class names could not be used in instanceof checks under some circumstances.

Version 1.2.0 (2015-03-22)

Changed

  • To ensure compatibility with PHP 7, the following node classes have been renamed:

      OLD                             => NEW
  PhpParser\Node\Expr\Cast\Bool   => PhpParser\Node\Expr\Cast\Bool_
  PhpParser\Node\Expr\Cast\Int    => PhpParser\Node\Expr\Cast\Int_
  PhpParser\Node\Expr\Cast\Object => PhpParser\Node\Expr\Cast\Object_
  PhpParser\Node\Expr\Cast\String => PhpParser\Node\Expr\Cast\String_
  PhpParser\Node\Scalar\String    => PhpParser\Node\Scalar\String_

    The previous class names are still supported as aliases. However it is strongly encouraged to use the new names in order to make your code compatible with PHP 7.

  • Subnodes are now stored using real properties instead of an array. This improves performance and memory usage of the initial parse and subsequent node tree operations. The NodeAbstract class still supports the old way of specifying subnodes, however this is deprecated. In any case properties that are assigned to a node after creation will no longer be considered as subnodes.

  • Methods and property declarations will no longer set the Stmt\Class_::MODIFIER_PUBLIC flag if no visibility is explicitly given. However the isPublic() method will continue to return true. This allows you to distinguish whether a method/property is explicitly or implicitly public and control the pretty printer output more precisely.

  • The Stmt\Class_, Stmt\Interface_ and Stmt\Trait_ nodes now inherit from Stmt\ClassLike, which provides a getMethods() method. Previously this method was only available on Stmt\Class_.

  • Support including the bootstrap.php file multiple times.

  • Make documentation and tests part of the release tarball again.

  • Improve support for HHVM and PHP 7.

Added

  • Added support for PHP 7 return type declarations. This adds an additional returnType subnode to Stmt\Function_, Stmt\ClassMethod and Expr\Closure.

  • Added support for the PHP 7 null coalesce operator ??. The operator is represented by Expr\BinaryOp\Coalesce.

  • Added support for the PHP 7 spaceship operator <=>. The operator is represented by Expr\BinaryOp\Spaceship.

  • Added use builder.

  • Added global namespace support to the namespace builder.

  • Added a constructor flag to NodeTraverser, which disables cloning of nodes.

Version 1.1.0 (2015-01-18)

  • Methods that do not specify an explicit visibility (e.g. function method()) will now have the MODIFIER_PUBLIC flag set. This also means that their isPublic() method will return true.

  • Declaring a property as abstract or final is now an error.

  • The Lexer and Lexer\Emulative classes now accept an $options array in their constructors. Currently only the usedAttributes option is supported, which determines which attributes will be added to AST nodes. In particular it is now possible to add information on the token and file positions corresponding to a node. For more details see the Lexer component documentation.

  • Node visitors can now return NodeTraverser::DONT_TRAVERSE_CHILDREN from enterNode() in order to skip all children of the current node, for all visitors.

  • Added builders for traits and namespaces.

  • The class, interface, trait, function, method and property builders now support adding doc comments using the setDocComment() method.

  • Added support for fully-qualified and namespace-relative names in builders. No longer allow use of name component arrays.

  • Do not add documentation and tests to distribution archive files.

Version 1.0.2 (2014-11-04)

  • The NameResolver visitor now also resolves names in trait adaptations (aliases and precedence declarations).

  • Remove stray whitespace when pretty-printing trait adaptations that only change visibility.

Version 1.0.1 (2014-10-14)

  • Disallow new expressions without a class name. Previously new; was accidentally considered to be valid code.

  • Support T_ONUMBER token used by HHVM.

  • Add ability to directly pass code to the php-parse.php script.

  • Prevent truncation of var_dump() output in the php-parse.php script if XDebug is used.

Version 1.0.0 (2014-09-12)

  • [BC] Removed deprecated Template and TemplateLoader classes.

  • Fixed XML unserializer to properly work with new namespaced node names.

Version 1.0.0-beta2 (2014-08-31)

  • [PHP 5.6] Updated support for constant scalar expressions to comply with latest changes. This means that arrays and array dimension fetches are now supported as well.

  • [PHP 5.6] Direct array dereferencing of constants is supported now, i.e. both FOO[0] and Foo::BAR[0] are valid now.

  • Fixed handling of special class names (self, parent and static) in the name resolver to be case insensitive. Additionally the name resolver now enforces that special class names are only used as unqualified names, e.g. \self is considered invalid.

  • The case of references to the static class name is now preserved. Previously static was always lowercased, regardless of the case used in the source code.

  • The autoloader now only requires a file if it exists. This allows usages like class_exists('PhpParser\NotExistingClass').

  • Added experimental bin/php-parse.php script, which is intended to help exploring and debugging the node tree.

  • Separated the parser implemention (in lib/PhpParser/ParserAbstract.php) and the generated data (in lib/PhpParser/Parser.php). Furthermore the parser now uses meaningful variable names and contains comments explaining their usage.

Version 1.0.0-beta1 (2014-03-27)

  • [BC] PHP-Parser now requires PHP 5.3 or newer to run. It is however still possible to parse PHP 5.2 source code, while running on a newer version.

  • [BC] The library has been moved to use namespaces with the PhpParser vendor prefix. However, the old names using underscores are still available as aliases, as such most code should continue running on the new version without further changes.

    However, code performing dispatch operations on Node::getType() may be affected by some of the name changes. For example a + node will now return type Expr_BinaryOp_Plus instead of Expr_Plus. In particular this may affect custom pretty printers.

    Due to conflicts with reserved keywords, some class names now end with an underscore, e.g. PHPParser_Node_Stmt_Class is now PhpParser\Node\Stmt\Class_. (But as usual, the old name is still available)

  • [PHP 5.6] Added support for the power operator ** (node Expr\BinaryOp\Pow) and the compound power assignment operator **= (node Expr\AssignOp\Pow).

  • [PHP 5.6] Added support for variadic functions: Param nodes now have variadic as a boolean subnode.

  • [PHP 5.6] Added support for argument unpacking: Arg nodes now have unpack as a boolean subnode.

  • [PHP 5.6] Added support for aliasing of functions and constants. Stmt\Use_ nodes now have an integral type subnode, which is one of Stmt\Use_::TYPE_NORMAL (use), Stmt\Use_::TYPE_FUNCTION (use function) or Stmt\Use_::TYPE_CONSTANT (use const).

    The NameResolver now also supports resolution of such aliases.

  • [PHP 5.6] Added support for constant scalar expressions. This means that certain expressions are now allowed as the initializer for constants, properties, parameters, static variables, etc.

  • [BC] Improved pretty printing of empty statements lists, which are now printed as {\n} instead of {\n \n}. This changes the behavior of the protected PrettyPrinterAbstract::pStmts() method, so custom pretty printing code making use it of may need to be adjusted.

  • Changed the order of some subnodes to be consistent with their order in the sour code. For example Stmt\If->cond will now appear before Stmt\If->stmts etc.

  • Added Scalar\MagicConstant->getName(), which returns the name of the magic constant (e.g. __CLASS__).

The following changes are also included in 0.9.5:

  • [BC] Deprecated PHPParser_Template and PHPParser_TemplateLoader. This functionality does not belong in the main project and - as far as I know - nobody is using it.

  • Add NodeTraverser::removeVisitor() method, which removes a visitor from the node traverser. This also modifies the corresponding NodeTraverserInterface.

  • Fix alias resolution in NameResolver: Class names are now correctly handled as case-insensitive.

  • The undefined variable error, which is used to the lexer to reset the error state, will no longer interfere with custom error handlers.

This changelog only includes changes from the 1.0 series. For older changes see the 0.9 series changelog.
