Version 0.9.5-dev

  • 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.

Version 0.9.4 (25.08.2013)

  • [PHP 5.5] Add support for ClassName::class. This is parsed as an Expr_ClassConstFetch with 'class' being the constant name.

  • Syntax errors now include information on expected tokens and mimic the format of PHP's own (pre 5.4) error messages. Example:

      Old: Unexpected token T_STATIC on line 1
  New: Syntax error, unexpected T_STATIC, expecting T_STRING or T_NS_SEPARATOR or '{'

  • PHPParser_PrettyPrinter_Zend was renamed to PHPParser_PrettyPrinter_Default as the default pretty printer only very loosely applies the Zend Coding Standard. The class PHPParser_PrettyPrinter_Zend extends PHPParser_PrettyPrinter_Default to maintain backwards compatibility.

  • The pretty printer now prints namespaces in semicolon-style if possible (i.e. if the file does not contain a global namespace declaration).

  • Added prettyPrintFile(array $stmts) method which will pretty print a file of statements including the opening <?php tag if it is required. Use of this method will also eliminate the unnecessary <?php ?> at the start and end of files using inline HTML.

  • There now is a builder for interfaces (PHPParser_Builder_Interface).

  • An interface for the node traversation has been added: PHPParser_NodeTraverserInterface

  • Fix pretty printing of include expressions (precedence information was missing).

  • Fix "undefined index" notices when generating the expected tokens for a syntax error.

  • Improve performance of PrettyPrinter construction by no longer using the uniqid() function.

Version 0.9.3 (22.11.2012)

  • [BC] As list() in foreach is now supported the structure of list assignments changed:

    1. There is no longer a dedicated AssignList node; instead a normal Assign node is used with a List as var.
    2. Nested lists are now List nodes too, instead of just arrays.

  • [BC] As arbitrary expressions are allowed in empty() now its subnode was renamed from var to expr.

  • [BC] The protected pSafe() method in PrettyPrinterAbstract was renamed to pNoIndent().

  • [PHP 5.5] Add support for arbitrary expressions in empty().

  • [PHP 5.5] Add support for constant array / string dereferencing. Examples: "foo"[2], [1, 2, 3][2]

  • [PHP 5.5] Add support for yield expressions. This adds a new Yield expression type, with subnodes key and value.

  • [PHP 5.5] Add support for finally. This adds a new finallyStmts subnode to the TryCatch node. If there is no finally clause it will be null.

  • [PHP 5.5] Add support for list() destructuring of foreach values. Example: foreach ($coords as list($x, $y)) { ... }

  • Improve pretty printing of expressions by printing less unnecessary parentheses. In particular concatenations are now printed as $a . $b . $c . $d . $e rather than $a . ($b . ($c . ($d . $e))). This is implemented by taking operator associativity into account. New protected methods added to the pretty printer are pPrec(), pInfixOp(), pPrefixOp() and pPostfixOp(). This also fixes an issue with extraneous parentheses in closure bodies.

  • Fix formatting of fall-through case statements in the Zend pretty printer.

  • Fix parsing of $foo =& new Bar. It is now properly parsed as AssignRef (instead of Assign).

  • Fix assignment of $endAttributes. Sometimes the attributes of the token right after the node were assigned, rather than the attributes of the last token in the node.

  • rebuildParser.php is now designed to be run from the command line rather than from the browser.

Version 0.9.2 (07.07.2012)

  • Add Class->getMethods() function, which returns all methods contained in the stmts array of the class node. This does not take inherited methods into account.

  • Add isPublic(), isProtected(), isPrivate(). isAbstract(), isFinal() and isStatic() accessors to the ClassMethod, Property and Class nodes. (Property and Class obviously only have the accessors relevant to them.)

  • Fix parsing of new expressions in parentheses, e.g. return(new Foo);.

  • [BC] Due to the below changes nodes now optionally accept an $attributes array as the last parameter, instead of the previously used $line and $docComment parameters.

  • Add mechanism for adding attributes to nodes in the lexer.

    The following attributes are now added by default:

    • startLine: The line the node started in.
    • endLine: The line the node ended in.
    • comments: An array of comments. The comments are instances of PHPParser_Comment (or PHPParser_Comment_Doc for doc comments).

    The methods getLine() and setLine() still exist and function as before, but internally operator on the startLine attribute.

    getDocComment() also continues to exist. It returns the last comment in the comments attribute if it is a doc comment, otherwise null. As getDocComment() now returns a comment object (which can be modified using ->setText()) the setDocComment() method was removed. Comment objects implement a __toString() method, so getDocComment() should continue to work properly with old code.

  • [BC] Use inject-once approach for lexer:

    Now the lexer is injected only once when creating the parser. Instead of

      $parser = new PHPParser_Parser;
  $parser->parse(new PHPParser_Lexer($code));
  $parser->parse(new PHPParser_Lexer($code2));

    you write:

      $parser = new PHPParser_Parser(new PHPParser_Lexer);
  $parser->parse($code);
  $parser->parse($code2);

  • Fix NameResolver visitor to also resolve class names in catch blocks.

Version 0.9.1 (24.04.2012)

  • Add ability to add attributes to nodes:

    It is now possible to add attributes to a node using $node->setAttribute('name', 'value') and to retrieve them using $node->getAttribute('name' [, 'default']). Additionally the existance of an attribute can be checked with $node->hasAttribute('name') and all attributes can be returned using $node->getAttributes().

  • Add code generation features: Builders and templates.

    For more infos, see the code generation documentation.

  • [BC] Don't traverse nodes merged by another visitor:

    If a NodeVisitor returns an array of nodes to merge, these will no longer be traversed by all other visitors. This behavior only caused problems.

  • Fix line numbers for some list structures.

  • Fix XML unserialization of empty nodes.

  • Fix parsing of integers that overflow into floats.

  • Fix emulation of NOWDOC and binary floats.

Version 0.9.0 (05.01.2012)

First version.
