Version 4.2.5-dev

Nothing yet.

Version 4.2.4 (2019-09-01)

Added

  • Added getProperties(), getConstants() and getTraitUses() to ClassLike. (#629, #630)

Fixed

  • Fixed flexible heredoc emulation to check for digits after the end label. This synchronizes behavior with the upcoming PHP 7.3.10 release.

Version 4.2.3 (2019-08-12)

Added

  • [PHP 7.4] Add support for numeric literal separators. (#615)

Fixed

  • Fixed resolution of return types for arrow functions. (#613)
  • Fixed compatibility with PHP 7.4.

Version 4.2.2 (2019-05-25)

Added

  • [PHP 7.4] Add support for arrow functions using a new Expr\ArrowFunction node. (#602)
  • [PHP 7.4] Add support for array spreads, using a new unpack subnode on ArrayItem. (#609)
  • Added support for inserting into empty list nodes in the formatting preserving pretty printer.

Changed

  • php-parse will now print messages to stderr, so that stdout only contains the actual result of the operation (such as a JSON dump). (#605)

Fixed

  • Fixed attribute assignment for zero-length nop statements, and a related assertion failure in the formatting-preserving pretty printer. (#589)

Version 4.2.1 (2019-02-16)

Added

  • [PHP 7.4] Add support for ??= operator through a new AssignOp\Coalesce node. (#575)

Version 4.2.0 (2019-01-12)

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).

Version 4.1.1 (2018-12-26)

Fixed

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

Added

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

Version 4.1.0 (2018-10-10)

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.

Version 4.0.4 (2018-09-18)

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().

Version 4.0.3 (2018-07-15)

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)

Version 4.0.2 (2018-06-03)

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)).

Version 4.0.1 (2018-03-25)

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()

Version 4.0.0 (2018-02-28)

  • No significant code changes since the beta 1 release.

Version 4.0.0-beta1 (2018-01-27)

Fixed

  • In formatting-preserving pretty printer: Fixed indentation when inserting into lists. (#466)

Added

  • In formatting-preserving pretty printer: Improved formatting of elements inserted into multi-line arrays.

Removed

  • The Autoloader class has been removed. It is now required to use the Composer autoloader.

Version 4.0.0-alpha3 (2017-12-26)

Fixed

  • In the formatting-preserving pretty printer: * Fixed comment indentation. * Fixed handling of inline HTML in the fallback case. * Fixed insertion into list nodes that require creation of a code block.

Added

  • Added support for inserting at the start of list nodes in formatting-preserving pretty printer.

Version 4.0.0-alpha2 (2017-11-10)

Added

  • In the formatting-preserving pretty printer: * Added support for changing modifiers. * Added support for anonymous classes. * Added support for removing from list nodes. * Improved support for changing comments.
  • Added start token offsets to comments.

Version 4.0.0-alpha1 (2017-10-18)

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.

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.

Version 3.1.5 (2018-02-28)

Fixed

  • Fixed duplicate comment assignment in switch statements. (#469)
  • Improve compatibility with PHP-Scoper. (#477)

Version 3.1.4 (2018-01-25)

Fixed

  • Fixed pretty printing of -(-$x) and +(+$x). (#459)

Version 3.1.3 (2017-12-26)

Fixed

  • Improve compatibility with php-scoper, by supporting prefixed namespaces in NodeAbstract::getType().

Version 3.1.2 (2017-11-04)

Fixed

  • Comments on empty blocks are now preserved on a Stmt\Nop node. (#382)

Added

  • Added kind attribute for Stmt\Namespace_ node, which is one of KIND_SEMICOLON or KIND_BRACED. (#417)
  • Added setDocComment() method to namespace builder. (#437)

Version 3.1.1 (2017-09-02)

Fixed

  • Fixed syntax error on comment after brace-style namespace declaration. (#412)
  • Added support for TraitUse statements in trait builder. (#413)

Version 3.1.0 (2017-07-28)

Added

  • [PHP 7.2] Added support for trailing comma in group use statements.
  • [PHP 7.2] Added support for object type. This means object types will now be represented as a builtin type (a simple "object" string), rather than a class Name.

Fixed

  • Floating-point numbers are now printed correctly if the LC_NUMERIC locale uses a comma as decimal separator.

Changed

  • Name::$parts is no longer deprecated.

Version 3.0.6 (2017-06-28)

Fixed

  • Fixed the spelling of Class_::VISIBILITY_MODIFIER_MASK. The previous spelling of Class_::VISIBILITY_MODIFER_MASK is preserved for backwards compatibility.
  • The pretty printing will now preserve comments inside array literals and function calls by printing the array items / function arguments on separate lines. Array literals and functions that do not contain comments are not affected.

Added

  • Added Builder\Param::makeVariadic().

Deprecated

  • The Node::setLine() method has been deprecated.

Version 3.0.5 (2017-03-05)

Fixed

  • Name resolution of NullableTypes is now performed earlier, so that a fully resolved signature is available when a function is entered. (#360)
  • Error nodes are now considered empty, while previously they extended until the token where the error occurred. This made some nodes larger than expected. (#359)
  • Fixed notices being thrown during error recovery in some situations. (#362)

Version 3.0.4 (2017-02-10)

Fixed

  • Fixed some extensibility issues in pretty printer (pUseType() is now public and pPrec() calls into p(), instead of directly dispatching to the type-specific printing method).
  • Fixed notice in bin/php-parse script.

Added

  • Error recovery from missing semicolons is now supported in more cases.
  • Error recovery from trailing commas in positions where PHP does not support them is now supported.

Version 3.0.3 (2017-02-03)

Fixed

  • In "$foo[0]" the 0 is now parsed as an LNumber rather than String. (#325)
  • Ensure integers and floats are always pretty printed preserving semantics, even if the particular value can only be manually constructed.
  • Throw a LogicException when trying to pretty-print an Error node. Previously this resulted in an undefined method exception or fatal error.

Added

  • [PHP 7.1] Added support for negative interpolated offsets: "$foo[-1]"
  • Added preserveOriginalNames option to NameResolver. If this option is enabled, an originalName attribute, containing the unresolved name, will be added to each resolved name.
  • Added php-parse --with-positions option, which dumps nodes with position information.

Deprecated

  • The XML serializer has been deprecated. In particular, the classes Serializer\XML, Unserializer\XML, as well as the interfaces Serializer and Unserializer are deprecated.

Version 3.0.2 (2016-12-06)

Fixed

  • Fixed name resolution of nullable types. (#324)
  • Fixed pretty-printing of nullable types.

Version 3.0.1 (2016-12-01)

Fixed

  • Fixed handling of nested list()s: If the nested list was unkeyed, it was directly included in the list items. If it was keyed, it was wrapped in ArrayItem. Now nested List_ nodes are always wrapped in ArrayItems. (#321)

Version 3.0.0 (2016-11-30)

Added

  • Added support for dumping node positions in the NodeDumper through the dumpPositions option.
  • Added error recovery support for $, new, Foo::.

Version 3.0.0-beta2 (2016-10-29)

This release primarily improves our support for error recovery.

Added

  • Added Node::setDocComment() method.
  • Added Error::getMessageWithColumnInfo() method.
  • Added support for recovery from lexer errors.
  • Added support for recovering from "special" errors (i.e. non-syntax parse errors).
  • Added precise location information for lexer errors.
  • Added ErrorHandler interface, and ErrorHandler\Throwing and ErrorHandler\Collecting as specific implementations. These provide a general mechanism for handling error recovery.
  • Added optional ErrorHandler argument to Parser::parse(), Lexer::startLexing() and NameResolver::__construct().
  • The NameResolver now adds a namespacedName attribute on name nodes that cannot be statically resolved (unqualified unaliased function or constant names in namespaces).

Fixed

  • Fixed attribute assignment for GroupUse prefix and variables in interpolated strings.

Changed

  • The constants on NameTraverserInterface have been moved into the NameTraverser class.
  • Due to the error handling changes, the Parser interface and Lexer API have changed.
  • The emulative lexer now directly postprocesses tokens, instead of using ~__EMU__~ sequences. This changes the protected API of the lexer.
  • The Name::slice() method now returns null for empty slices, previously new Name([]) was used. Name::concat() now also supports concatenation with null.

Removed

  • Removed Name::append() and Name::prepend(). These mutable methods have been superseded by the immutable Name::concat().
  • Removed Error::getRawLine() and Error::setRawLine(). These methods have been superseded by Error::getStartLine() and Error::setStartLine().
  • Removed support for node cloning in the NodeTraverser.
  • Removed $separator argument from Name::toString().
  • Removed throw_on_error parser option and Parser::getErrors() method. Use the ErrorHandler mechanism instead.

Version 3.0.0-beta1 (2016-09-16)

Added

  • [7.1] Function/method and parameter builders now support PHP 7.1 type hints (void, iterable and nullable types).
  • Nodes and Comments now implement JsonSerializable. The node kind is stored in a nodeType property.
  • The InlineHTML node now has an hasLeadingNewline attribute, that specifies whether the preceding closing tag contained a newline. The pretty printer honors this attribute.
  • Partial parsing of $obj-> (with missing property name) is now supported in error recovery mode.
  • The error recovery mode is now exposed in the php-parse script through the --with-recovery or -r flags.

The following changes are also part of PHP-Parser 2.1.1:

  • The PHP 7 parser will now generate a parse error for $var =& new Obj assignments.
  • Comments on free-standing code blocks will now be retained as comments on the first statement in the code block.

Version 3.0.0-alpha1 (2016-07-25)

Added

  • [7.1] Added support for void and iterable types. These will now be represented as strings (instead of Name instances) similar to other builtin types.
  • [7.1] Added support for class constant visibility. The ClassConst node now has a flags subnode holding the visibility modifier, as well as isPublic(), isProtected() and isPrivate() methods. The constructor changed to accept the additional subnode.
  • [7.1] Added support for nullable types. These are represented using a new NullableType node with a single type subnode.
  • [7.1] Added support for short array destructuring syntax. This means that Array nodes may now appear as the left-hand-side of assignments and foreach value targets. Additionally the array items may now contain null values if elements are skipped.
  • [7.1] Added support for keys in list() destructuring. The List subnode vars has been renamed to items and now contains ArrayItems instead of plain variables.
  • [7.1] Added support for multi-catch. The Catch subnode type has been renamed to types and is now an array of Names.
  • Name::slice() now supports lengths and negative offsets. This brings it in line with array_slice() functionality.

Changed

Due to PHP 7.1 support additions described above, the node structure changed as follows:

  • void and iterable types are now stored as strings if the PHP 7 parser is used.
  • The ClassConst constructor changed to accept an additional flags subnode.
  • The Array subnode items may now contain null elements (destructuring).
  • The List subnode vars has been renamed to items and now contains ArrayItems instead of plain variables.
  • The Catch subnode type has been renamed to types and is now an array of Names.

Additionally the following changes were made:

  • The type subnode on Class, ClassMethod and Property has been renamed to flags. The type subnode has retained for backwards compatibility and is populated to the same value as flags. However, writes to type will not update flags.
  • The TryCatch subnode finallyStmts has been replaced with a finally subnode that holds an explicit Finally node. This allows for more accurate attribute assignment.
  • The Trait constructor now has the same form as the Class and Interface constructors: It takes an array of subnodes. Unlike classes/interfaces, traits can only have a stmts subnode.
  • The NodeDumper now prints class/method/property/constant modifiers, as well as the include and use type in a textual representation, instead of only showing the number.
  • All methods on PrettyPrinter\Standard are now protected. Previously most of them were public.

Removed

  • Removed support for running on PHP 5.4. It is however still possible to parse PHP 5.2-5.4 code while running on a newer version.
  • The deprecated Comment::setLine() and Comment::setText() methods have been removed.
  • The deprecated Name::set(), Name::setFirst() and Name::setLast() methods have been removed.

Version 2.1.1 (2016-09-16)

Changed

  • The pretty printer will now escape all control characters in the range \x00-\x1F inside double quoted strings. If no special escape sequence is available, an octal escape will be used.
  • The quality of the error recovery has been improved. In particular unterminated expressions should be handled more gracefully.
  • The PHP 7 parser will now generate a parse error for $var =& new Obj assignments.
  • Comments on free-standing code blocks will no be retained as comments on the first statement in the code block.

Version 2.1.0 (2016-04-19)

Fixed

  • Properly support B"" strings (with uppercase B) in a number of places.
  • Fixed reformatting of indented parts in a certain non-standard comment style.

Added

  • Added dumpComments option to node dumper, to enable dumping of comments associated with nodes.
  • Added Stmt\Nop node, that is used to collect comments located at the end of a block or at the end of a file (without a following node with which they could otherwise be associated).
  • Added kind attribute to Expr\Exit to distinguish between exit and die.
  • Added kind attribute to Scalar\LNumber to distinguish between decimal, binary, octal and hexadecimal numbers.
  • Added kind attribute to Expr\Array to distinguish between array() and [].
  • Added kind attribute to Scalar\String and Scalar\Encapsed to distinguish between single-quoted, double-quoted, heredoc and nowdoc string.
  • Added docLabel attribute to Scalar\String and Scalar\Encapsed, if it is a heredoc or nowdoc string.
  • Added start file offset information to Comment nodes.
  • Added setReturnType() method to function and method builders.
  • Added -h and --help options to php-parse script.

Changed

  • Invalid octal literals now throw a parse error in PHP 7 mode.
  • The pretty printer takes all the new attributes mentioned in the previous section into account.
  • The protected AbstractPrettyPrinter::pComments() method no longer returns a trailing newline.
  • The bundled autoloader supports library files being stored in a different directory than PhpParser for easier downstream distribution.

Deprecated

  • The Comment::setLine() and Comment::setText() methods have been deprecated. Construct new objects instead.

Removed

  • The internal (but public) method Scalar\LNumber::parse() has been removed. A non-internal LNumber::fromString() method has been added instead.

Version 2.0.1 (2016-02-28)

Fixed

  • declare() {} and declare(); are not semantically equivalent and will now result in different ASTs. The format case will have an empty stmts array, while the latter will set stmts to null.
  • Magic constants are now supported as semi-reserved keywords.
  • A shebang line like #!/usr/bin/env php is now allowed at the start of a namespaced file. Previously this generated an exception.
  • The prettyPrintFile() method will not strip a trailing ?> from the raw data that follows a __halt_compiler() statement.
  • The prettyPrintFile() method will not strip an opening <?php if the file starts with a comment followed by InlineHTML.

Version 2.0.0 (2015-12-04)

Changed

  • String parts of encapsed strings are now represented using Scalar\EncapsStringPart nodes. Previously raw strings were used. This affects the parts child of Scalar\Encaps and Expr\ShellExec. The change has been done to allow assignment of attributes to encapsed string parts.

Version 2.0.0-beta1 (2015-10-21)

Fixed

  • Fixed issue with too many newlines being stripped at the end of heredoc/nowdoc strings in some cases. (#227)

Changed

  • Update group use support to be in line with recent PHP 7.0 builds.
  • Renamed php-parse.php to php-parse and registered it as a composer bin.
  • Use composer PSR-4 autoloader instead of custom autoloader.
  • Specify phpunit as a dev dependency.

Added

  • Added shortArraySyntax option to pretty printer, to print all arrays using short syntax.

Version 2.0.0-alpha1 (2015-07-14)

A more detailed description of backwards incompatible changes can be found in the upgrading guide.

Removed

  • Removed support for running on PHP 5.3. It is however still possible to parse PHP 5.2 and PHP 5.3 code while running on a newer version.
  • Removed legacy class name aliases. This includes the old non-namespaced class names and the old names for classes that were renamed for PHP 7 compatibility.
  • Removed support for legacy node format. All nodes must have a getSubNodeNames() method now.

Added

  • Added support for remaining PHP 7 features that were not present in 1.x: * Group use declarations. These are represented using Stmt\GroupUse nodes. Furthermore a type attribute was added to Stmt\UseUse to handle mixed group use declarations. * Uniform variable syntax. * Generalized yield operator. * Scalar type declarations. These are presented using 'bool', 'int', 'float' and 'string' as the type. The PHP 5 parser also accepts these, however they'll be Name instances there. * Unicode escape sequences.
  • Added PhpParser\ParserFactory class, which should be used to create parser instances.
  • Added Name::concat() which concatenates two names.
  • Added Name->slice() which takes a subslice of a name.

Changed

  • PhpParser\Parser is now an interface, implemented by Parser\Php5, Parser\Php7 and Parser\Multiple. The Multiple parser will try multiple parsers, until one succeeds.
  • Token constants are now defined on PhpParser\Parser\Tokens rather than PhpParser\Parser.
  • The Name->set(), Name->append(), Name->prepend() and Name->setFirst() methods are deprecated in favor of Name::concat() and Name->slice().
  • The NodeTraverser no longer clones nodes by default. The old behavior can be restored by passing true to the constructor.
  • The constructor for Scalar nodes no longer has a default value. E.g. new LNumber() should now be written as new LNumber(0).

This changelog only includes changes from the 2.0 series. For older changes see the 1.x series changelog and the 0.9 series changelog.
