Version 1.4.2-dev
-----------------
Nothing yet.
Version 1.4.1 (2015-09-19)
--------------------------
### Fixed
* Fixed issue with too many newlines being stripped at the end of heredoc/nowdoc strings in some
cases. (#227)
Version 1.4.0 (2015-07-14)
--------------------------
### Added
* Added interface `PhpParser\Node\FunctionLike`, which is implemented by `Stmt\ClassMethod`,
`Stmt\Function_` and `Expr\Closure` nodes. This interface provides getters for their common
subnodes.
* Added `Node\Stmt\ClassLike::getMethod()` to look up a specific method on a class/interface/trait.
### Fixed
* Fixed `isPublic()` return value for implicitly public properties and methods that define and
additional modifier like `static` or `abstract`.
* Properties are now accepted by the trait builder.
* Fixed `__HALT_COMPILER_OFFSET__` support on HHVM.
Version 1.3.0 (2015-05-02)
--------------------------
### Added
* Errors can now store the attributes of the node/token where the error occurred. Previously only the start line was
stored.
* If file positions are enabled in the lexer, errors can now provide column information if it is available. See
[documentation](https://github.com/nikic/PHP-Parser/blob/master/doc/component/Error.markdown#column-information).
* The parser now provides an experimental error recovery mode, which can be enabled by disabling the `throwOnError`
parser option. In this mode the parser will try to construct a partial AST even if the code is not valid PHP. See
[documentation](https://github.com/nikic/PHP-Parser/blob/master/doc/component/Error.markdown#error-recovery).
* Added support for PHP 7 `yield from` expression. It is represented by `Expr\YieldFrom`.
* Added support for PHP 7 anonymous classes. These are represented by ordinary `Stmt\Class_` nodes with the name set to
`null`. Furthermore this implies that `Expr\New_` can now contain a `Stmt\Class_` in its `class` subnode.
### Fixed
* Fixed registration of PHP 7 aliases, for the case where the old name was used before the new name.
* Fixed handling of precedence when pretty-printing `print` expressions.
* Floating point numbers are now pretty-printed with a higher precision.
* Checks for special class names like `self` are now case-insensitive.
Version 1.2.2 (2015-04-03)
--------------------------
* The `NameResolver` now resolves parameter type hints when entering the function/method/closure node. As such other
visitors running after it will be able to make use of the resolved names at that point already.
* The autoloader no longer sets the `unserialize_callback_func` ini option on registration - this is not necessary and
may cause issues when running PhpUnit tests with process isolation.
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](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.
