PHP-Parser/CHANGELOG.md

Version 1.0.0-dev

Nothing yet.

Version 1.0.0-beta1 (27.03.2014)

• [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-dev:

• [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.
