PHP-Parser/CHANGELOG.md

Version 1.1.1-dev
-----------------

Nothing yet.

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](https://github.com/nikic/PHP-Parser/blob/master/doc/component/Lexer.markdown) 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.
